Of Mouses and Mans: A Test of Errorless Versus Error-Based Learning in Children

For both adults and children, learning from one's mistakes (error-based learning) has been shown to be advantageous over avoiding errors altogether (errorless learning) in pedagogical settings. However, it remains unclear whether this advantage carries over to nonpedagogical settings in children, who mostly learn language in such settings. Using irregular plurals (e.g., "mice") as a test case, we conducted a corpus analysis (N = 227) and two preregistered experiments (N = 56, N = 99), to investigate the potency of error-based learning as a mechanism for language acquisition in 3- and 4-year-old children. The results of the corpus analysis showed that incidental feedback after errors, in the form of caregivers' reformulations of children's errors, was relatively infrequent, had modest informational value, and was rarely used by children to correct their errors immediately. The following two experiments contrasted error-based learning with errorless learning, where the correct utterance was modeled for the child before a potential error was committed. The results showed that error-based learning was not always effective, and when it was, it was certainly not superior to errorless learning. Collectively, these findings question the extension of the benefits of error-based learning from pedagogical to nonpedagogical settings and define constraints under which one mechanism may be more beneficial to learning than the other.

Toddlers' prior social experience with speakers influences their word learning

Toddlers prefer to learn from familiar adults, particularly their caregivers, and perform better on word learning tasks when taught by caregivers than by strangers. However, it remains unclear why toddlers learn better from caregivers than from strangers. One possibility is that toddlers are more receptive to learning from individuals whom they have found to be engaging in previous interactions. The current study tested whether toddlers learn more from an unfamiliar adult who was previously engaging than from an unfamiliar adult who was previously unengaging. Toddlers (27-29 months, N = 40) were taught labels for novel objects by two different experimenters. Prior to word learning, toddlers watched pre-recorded videos of one experimenter utilizing engaging behaviors (i.e., using infant-directed speech, gestures, eye contact, and positive affect) and one experimenter utilizing unengaging behaviors (i.e., using adult-directed speech, no gestures, no eye contact, and neutral affect). Both experimenters were equally engaging during labeling. Word learning was then tested using a looking-while-listening paradigm. The results of linear mixed-effects model, cluster-based permutation, and growth curve analyses suggest heightened performance for words that were taught by the experimenter who was previously engaging. These results begin to reveal the kinds of social experiences that promote success in early word learning.

How does social contingency facilitate vocabulary development?

Previous research shows that infants of parents who are more likely to engage in socially contingent interactions with them tend to have larger vocabularies. An open question is how social contingency facilitates vocabulary growth. One possibility is that parents who speak in response to their infants more often produce larger amount of language input, which accelerates vocabulary growth. Another possibility is that the simplicity of contingent language input is especially suitable to support early word learning. A third possibility is that more evidence of the communicative nature of language, achieved through frequent contingent responses, helps infants build a link between their own words or vocalizations and others' behaviors. This link may lead to a better understanding of the communicative nature of language and further language advances, including vocabulary growth. To distinguish between these hypotheses, we analyzed the relations between parent-infant interactions when infants were 9 months and their vocabulary size at 12 months, using a naturalistic corpus. Our findings show that the frequency of parents' verbal contingent responses predicts receptive vocabulary size at 12 months and this predictive relation is unlikely to be due to the amount of language input or the simplicity of language within socially contingent interactions. RESEARCH HIGHLIGHTS: Infants of parents who respond to their vocalizations more often during the first year of life tend to have larger vocabularies in the second year. It is an open question what drives the predictive relation between parents' responsiveness and infants' vocabulary; we tested three hypotheses that offer competing explanations. More responsive parents might provide (1) more language input, (2) simpler language input, (3) more evidence of the communicative nature of language (via frequent responses). We find support for the third hypothesis; the frequency of parents' responses predicts infants' vocabularies above and beyond the amount and simplicity of language input.

Employing user-centered design to develop a remote technology kit for studying young children's social communication skills

OBJECTIVE

The COVID-19 pandemic required behavioral researchers to rapidly pivot to the implementation of remote study protocols to facilitate data collection. Remote implementation required robust and flexible research protocols including reliable audio/visual technology that met all the quality, security, and privacy hallmarks of lab-based equipment, while also being portable and usable by nontechnical staff and participants. The project's primary purpose was to develop a technology kit that could be deployed for data collection in homes with young children. The secondary objective was to determine the feasibility of the kit for use longitudinally across four disparate sites.

METHOD

User-centered design principles were employed in the development and implementation of a technology kit deployed across urban, suburban, and rural participant locations in four states. Preliminary feasibility and usability data were gathered to determine the reliability of the kit across three timepoints.

RESULTS

In study 1, a technology kit was constructed addressing all project needs including the provision of the internet to connect remotely with participants. Staff training protocols and participant-facing materials were developed to accompany deployment procedures. In study 2, data gathered in technology logs demonstrated successful capturing of video footage in 96% of opportunities with most technology challenges mitigated. Subsequent behavioral coding indicated 100% of captured assessment footage has been successfully coded to date. Moreover, participants needed less support for technology setup at their later timepoints, and staff rated the kit as highly usable.

CONCLUSION

This study offers a model for future development of technology use in remote community- and home-based pediatric research.

Contingency enables the formation of social expectations about an artificial agent

What environmental regularities support infant communicative learning from social interactions? We propose that infants allocate their attention toward and learn from external events that are contingent on their own behaviors. We tested the robustness of the influence of contingency on communicative learning by using a non-biological stimulus, a remote-controlled car, as the social partner. The car approached infants and produced a speech sound either contingently to infants' vocalizations or on a yoked schedule. Two additional groups had an unfamiliar human experimenter as their social partner in contingent and yoked control conditions. We assessed whether infants formed expectations about their partner's responsiveness to their vocalizations. Expectations made based on contingent responsiveness would support the role of contingency in promoting plasticity in early communicative learning. Infants across all conditions increased their vocalization rates when their partner paused in responding, suggesting that they expected their vocalizations to influence their partners' behavior. Infants vocalized significantly more to the social partner than their caregiver if they received contingent rather than yoked responses from the social partner, regardless of if the partner was a human or non-biological agent. Contingent responses to prelinguistic vocalizations facilitated the formation of expectations for interactivity of social partners.

The importance of mother-child interaction on smart device usage and behavior outcomes among toddlers: a longitudinal study

BACKGROUND

In recent years, smart devices have become an integral part of daily life. However, longitudinal studies, particularly those regarding the relationship between toddlers' smart device usage and behavioral outcomes, are limited. Understanding the impact of parent-child interactions on this relationship is crucial for enhancing toddlers' developmental outcomes. Accordingly, this study examined the influence of early screen time and media content exposure on toddlers' behaviors, as well as the positive effects of mother-child interactions on this influence.

METHODS

We used relevant data related to 277 children born between November 2016 and July 2020 and who were part of an ongoing prospective follow-up study conducted across five hospitals in Taipei City, Taiwan. We analyzed (1) data from maternal reports regarding children's behavior by using the Child Behavior Checklist (for ages 11/2-5 years), (2) assessments of mother-child interactions by using the Brigance Parent-Child Interactions Scale, and (3) self-reported parental data covering the first 3 postpartum years. Statistical analyses involved group-based trajectory modeling and multiple linear regression.

RESULTS

A considerable increase in screen time between the ages of 1 and 3 years was associated with less favorable behavioral outcomes at age 3. These outcomes included somatic complaints [adjusted beta coefficient (aβ) = 2.17, 95% confidence interval (CI) = 0.39-3.95, p-value = 0.01], withdrawal (aβ = 2.42, 95% CI = 0.15-4.69, p-value = 0.04), and aggressive behavior (aβ = 6.53, 95% CI = 0.25-12.81, p-value = 0.04). This association was particularly evident among children with lower levels of mother-child interaction. Nevertheless, positive mother-child interactions mitigated most of the adverse effects. Additionally, increased exposure to games and cartoons was associated with poorer behavioral outcomes in all children except for those experiencing positive mother-child interactions.

CONCLUSION

Early mother-child interactions play a crucial role in mitigating the risk of behavioral problems in toddlers who spend prolonged periods looking at screens and who are frequently exposed to game and cartoon content.

Building language learning: Relations between infant attention and social contingency in the first year of life

In Western societies, social contingency, or prompt and meaningful back-and-forth exchanges between infant and caregiver, is a powerful feature of the early language environment. Research suggests that infants with better attentional skills engage in more social contingency during interactions with adults and, in turn, social contingency supports infant attention. This reciprocity is theorized to build infant language skills as the adult capitalizes on and extends the infant's attention during socially contingent interactions. Using data from 104 infants and caregivers, this paper tests reciprocal relations between infant attention and social contingency at 6- and 12-months and the implications for infant vocabulary at 18-months. Infant attentional skills to social (women speaking) and nonsocial (objects dropping) events were assessed, and social contingency was examined during an 8-minute toy play interaction with a caregiver. Child receptive and expressive vocabulary was measured by caregiver-report. Both social and nonsocial attentional skills related to engagement in social contingency during caregiver-infant interaction, though only models that included social attention and social contingency predicted vocabulary. These findings provide empirical evidence for the proposed reciprocal relations between infant attention and social contingency as well as how they relate to later language.

A brief tablet-based intervention benefits linguistic and communicative abilities in toddlers and preschoolers

Young children's linguistic and communicative abilities are foundational for their academic achievement and overall well-being. We present the positive outcomes of a brief tablet-based intervention aimed at teaching toddlers and preschoolers new word-object and letter-sound associations. We conducted two experiments, one involving toddlers ( ~ 24 months old, n = 101) and the other with preschoolers ( ~ 42 months old, n = 152). Using a pre-post equivalent group design, we measured the children's improvements in language and communication skills resulting from the intervention. Our results showed that the intervention benefited toddlers' verbal communication and preschoolers' speech comprehension. Additionally, it encouraged vocalizations in preschoolers and enhanced long-term memory for the associations taught in the study for all participants. In summary, our study demonstrates that the use of a ludic tablet-based intervention for teaching new vocabulary and pre-reading skills can improve young children's linguistic and communicative abilities, which are essential for future development.

Right or wrong? How feedback content and source influence children's mathematics performance and persistence

The current study examined how different features of corrective feedback influenced children's performance and motivational outcomes on a mathematics task. Elementary school-aged children from the United States (N = 130; Mage = 7.61 years; 35% female; 60% White) participated in a Zoom session with a trained researcher. During the learning activity, children solved a series of mathematical equivalence problems and were assigned to different feedback conditions that varied in feedback content (correct answer alone vs. correct answer with verification) and feedback source (computer alone vs. computer with person). In terms of content, feedback with verification cues led to decreased persistence, decreased strategy variability, and higher reliance on entrenched strategies relative to feedback that contained the correct answer alone. In terms of source, feedback from the computer alone enhanced children's accuracy; however, the most resilient children received feedback from the computer and a person. Findings are discussed in light of existing feedback theories.

Digital Media and Developing Brains: Concerns and Opportunities

Purpose of Review

The incorporation of digital technologies and their use in youth's everyday lives has been increasing rapidly over the past several decades with possible impacts on youth development and mental health. This narrative review aimed to consider how the use of digital technologies may be influencing brain development underlying adaptive and maladaptive screen-related behaviors.

Recent Findings

To explore and provide direction for further scientific inquiry, an international group of experts considered what is known, important gaps in knowledge, and how a research agenda might be pursued regarding relationships between screen media activity and neurodevelopment from infancy through childhood and adolescence. While an understanding of brain-behavior relationships involving screen media activity has been emerging, significant gaps exist that have important implications for the health of developing youth.

Summary

Specific considerations regarding brain-behavior relationships involving screen media activity exist for infancy, toddlerhood, and early childhood; middle childhood; and adolescence. Transdiagnostic frameworks may provide a foundation for guiding future research efforts. Translating knowledge gained into better interventions and policy to promote healthy development is important in a rapidly changing digital technology environment.

Children build their vocabularies in noisy environments: The necessity of a cross-disciplinary approach to understand word learning

Research within the language sciences has informed our understanding of how children build vocabulary knowledge especially during early childhood and the early school years. However, to date, our understanding of word learning in children is based primarily on research in quiet laboratory settings. The everyday environments that children inhabit such as schools, homes, and day cares are typically noisy. To better understand vocabulary development, we need to understand the effects of background noise on word learning. To gain this understanding, a cross-disciplinary approach between researchers in the language and hearing sciences in partnership with parents, educators, and clinicians is ideal. Through this approach we can identify characteristics of effective vocabulary instruction that take into account the background noise present in children's learning environments. Furthermore, we can identify characteristics of children who are likely to struggle with learning words in noisy environments. For example, differences in vocabulary knowledge, verbal working memory abilities, and attention skills will likely influence children's ability to learn words in the presence of background noise. These children require effective interventions to support their vocabulary development which subsequently should support their ability to process and learn language in noisy environments. Overall, this cross-disciplinary approach will inform theories of language development and inform educational and intervention practices designed to support children's vocabulary development.

Exposure to Foreign Languages through Live Interaction Can Facilitate Children's Acceptance of Multiple Labeling Conventions across Languages

The current research examined whether children's expectations about labeling conventions can be influenced by limited exposure to a foreign language. Three- to four-year-old Korean children were presented with two speakers who each assigned a novel label either in Korean or Spanish to a novel object. Children were asked whether both labels were acceptable for the object. Children who had more exposure to a foreign language through live social interaction, but not through media, were more likely to accept both Korean and Spanish labels. These findings indicate the influence of social interaction in foreign language exposure on children's understanding of different labeling conventions.

Preschoolers ask questions about unknown words on video chat and in live interactions at similar rates

The COVID-19 pandemic has led to a major increase in digital interactions in early experience. A crucial question, given expanding virtual platforms, is whether preschoolers' active word learning behaviors extend to their interactions over video chat. When not provided with sufficient information to link new words to meanings, preschoolers drive their word learning by asking questions. In person, 5-year-olds focus their questions on unknown words compared with known words, highlighting their active word learning. Here, we investigated whether preschoolers' question-asking over video chat differs from in-person question-asking. In the study, 5-year-olds were instructed to move toys in response to known and unknown verbs on a video conferencing call (i.e., Zoom). Consistent with in-person results, video chat participants (n = 18) asked more questions about unknown words than about known words. The rate of question-asking about words across video chat and in-person formats did not differ. Differences in the types of questions asked about words indicate, however, that although video chat does not hinder preschoolers' active word learning, the use of video chat may influence how preschoolers request information about words.

Familial context influences media usage in 0- to 4-year old children

Background

The use of digital media (e.g., smartphones, tablets, etc.) and the Internet have become omnipresent for every age group and are part of children's and parents' everyday life. Focusing on young children, the availability of media devices, their use as well as associated problems (e.g., in social, emotional and motor development) have increased in recent years. Of particular interest for prevention of these problems in early childhood is the relationship between the familial context (parental digital media use, Problematic Internet Use, school graduation, presence of siblings) and the digital media use of infants and toddlers. The present study's goal was to describe media usage in 0-4-year-old children and to identify the potential relationship between familial context factors and child media usage.

Methods

The sample included N = 3,035 children aged 0 to 3;11 years (M = 17.37 months, SD = 13.68; 49.13% female). Recruitment took place within the framework of a restandardization study for a German developmental test. The parents of the participants answered a questionnaire on socio-demographics, on child media use, and on parental media use. Questions on parental media use included the full version of the Short Compulsive Internet Use Scale (S-CIUS).

Results

Significant increases in media usage times with child age were identified, but no significant gender differences. A multiple regression analysis revealed that increasing maternal total media usage time, a higher parental S-CIUS score, lower school leaving certificate of both mother and father, and increasing child's age led to higher child media usage time. Having siblings diminished young children's media usage in this study. Having more than one child and having children aged over a year was associated with a higher parental S-CIUS score.

Conclusion

Family factors such as maternal media use time, Problematic Internet Use and lower school graduation are significantly associated with young children's digital media use. Parents should be aware of their personal influence on their children's media use which might be due their role in terms of model learning.

How adults understand what young children say

Children's early speech often bears little resemblance to that of adults, and yet parents and other caregivers are able to interpret that speech and react accordingly. Here we investigate how adult listeners' inferences reflect sophisticated beliefs about what children are trying to communicate, as well as how children are likely to pronounce words. Using a Bayesian framework for modelling spoken word recognition, we find that computational models can replicate adult interpretations of children's speech only when they include strong, context-specific prior expectations about the messages that children will want to communicate. This points to a critical role of adult cognitive processes in supporting early communication and reveals how children can actively prompt adults to take actions on their behalf even when they have only a nascent understanding of the adult language. We discuss the wide-ranging implications of the powerful listening capabilities of adults for theories of first language acquisition.

Infants' and toddlers' language development during the pandemic: Socioeconomic status mattered

The disruption caused by the COVID-19 pandemic has raised concerns about children's development. Here, we examined the impact of the pandemic on Canadian infants' and toddlers' (N = 539) language development. Specifically, we assessed changes in 11- to 34-month-olds' activities that are known to affect vocabulary development (i.e., screen and reading times). We also compared these children's vocabulary sizes with those of 1365 children collected before the pandemic using standardized vocabulary assessments. Our results show that screen and reading times were most negatively affected in lower-income children. For vocabulary growth, no measurable change was detected in middle- and high-income children, but lower-income 19- to 29-month-olds fared worse during the pandemic than during pre-pandemic times. Moving forward, these data indicate that educators and policymakers should pay particular attention to children from families with lower socioeconomic status during times of crisis and stress.

Vulnerabilities Prompting Use of Technology and Screen by Mothers of Autistic Children in India: Lived Experiences and Comparison to Scientific Literature

Technology and screen media has its place in every home, yet the influences of the same are less known. This research aims to explore the vulnerabilities that prompt the mothers to use screen media for their children, prior to a diagnosis of autism for their child. It also aims to explore literature the influence of screen media on speech and language development in children. This study combined semi-structured interviews with 16 mothers of autistic children in Southern India and a scoping literature review that resulted in 24 articles. The literature refers to a positive influence when co-viewing with the child, and it predominantly highlights improvements in speech and not in language. The interviews revealed that screens were used as a means of support, a language and learning development tool, or as a calming technique. Thus, the study shows that the mothers resorted to screen use for their children more out of helplessness, and not as an informed choice. Mothers of autistic children clearly express their vulnerabilities and indicate feelings of being lost without advice, with regard to use of screen-time. This suggests a need for more research into how they can be supported.

Reexamining models of early learning in the digital age: Applications for learning in the wild

Young children are growing up in an increasingly complicated digital world. Laboratory-based research shows it is cognitively demanding to process and transfer information presented on screens during early childhood. Multiple explanations for this cognitive challenge have been proposed. This review provides an updated comprehensive framework that integrates prior theoretical explanations to develop new testable hypotheses. The review also considers the how the research can be generalized to the "wild" where children engage with multiple commercial products daily. It includes real-world applications for improving children's learning and memory from screen-based media by adding supportive cues and reducing distraction and interference. The review concludes with a call for future collaborative research between researchers, content developers, and families to better understand age-related changes in both short-term and long-term learning from digital media. Finally, policy makers need to be involved to ensure equitable access and to create a safe digital space for all families.

Parent coaching from 6 to 18 months improves child language outcomes through 30 months of age

Interventions focused on the home language environment have been shown to improve a number of child language outcomes in the first years of life. However, data on the longer-term effects of the intervention are still somewhat limited. The current study examines child vocabulary and complex speech outcomes (N = 59) during the year following completion of a parent-coaching intervention, which was previously found to increase the quantity of parent-child conversational turns and to improve child language outcomes through 18 months of age. Measures of parental language input, child speech output, and parent-child conversational turn-taking were manually coded from naturalistic home recordings (Language Environment Analysis System, LENA) at regular 4-month intervals when children were 6- to 24-months old. Child language skills were assessed using the MacArthur-Bates Communicative Development Inventory (CDI) at four time-points following the final intervention session (at 18, 24, 27, and 30 months). Vocabulary size and growth from 18 to 30 months was greater in the intervention group, even after accounting for differences in child language ability during the intervention period. The intervention group also scored higher on measures of speech length and grammatical complexity, and these effects were mediated by 18-month vocabulary. Intervention was associated with increased parent-child conversational turn-taking in home recordings at 14 months, and mediation analysis suggested that 14-month conversational turn-taking accounted for intervention-related differences in subsequent vocabulary. Together, the results suggest enduring, positive effects of parental language intervention and underscore the importance of interactive, conversational language experience during the first 2 years of life. RESEARCH HIGHLIGHTS: Parent coaching was provided as part of a home language intervention when children were 6-18 months of age. Naturalistic home language recordings showed increased parent-child conversational turn-taking in the intervention group at 14 months of age. Measures of productive vocabulary and complex speech indicated more advanced expressive language skills in the intervention group through 30 months of age, a full year after the final intervention session. Conversational turn-taking at 14 months predicted subsequent child vocabulary and accounted for differences in vocabulary size across the intervention and control groups.

Screen media exposure and young children's vocabulary learning and development: A meta-analysis

This meta-analysis synthesizes research on media use in early childhood (0-6 years), word-learning, and vocabulary size. Multi-level analyses included 266 effect sizes from 63 studies (Ntotal  = 11,413) published between 1988-2022. Among samples with information about race/ethnicity (51%) and sex/gender (73%), most were majority White/Non-Hispanic and between 40%-60% female. Analyses revealed a small overall positive relation between screen media exposure and vocabulary (r = .23). Experimental studies yielded a small-to-medium effect (r = .30), with stronger effects for e-books than TV/video or games/apps, and non-significant effects for video chat. In correlational studies, there was no overall association between vocabulary size and naturalistic media exposure (r = .07), with the exception of naturalistic exposure to educational media (r = .17).

The association between screen media quantity, content, and context and language development

This study investigates the influence of the quantity, content, and context of screen media use on the language development of 85 Saudi children aged 1 to 3 years. Surveys and weekly event-based diaries were employed to track children's screen use patterns. Language development was assessed using JISH Arabic Communicative Development Inventory (JACDI). Findings indicate that the most significant predictor of expressive and receptive vocabulary in 12- to 16-month-olds was screen media context (as measured by the frequency of interactive joint media engagements). In older children (17- to 36-month-olds), more screen time (as measured by the amount of time spent using screens, the prevalence of background TV at home, and the onset age of screen use) had the highest negative impact on expressive vocabulary and mean length of utterance. These findings support health recommendations on the negative effects of excessive screen time and the positive effects of co-viewing media with children.

Reducing harm and promoting positive media use strategies: new perspectives in understanding the impact of preschooler media use on health and development

Most children grow up in homes with easy access to multiple screens. Screen use by children between the ages of 0 to 5 has become a worldwide preoccupation. In the present narrative review, we examine child and parent screen use and its contribution to physical, cognitive, and social developmental outcomes. As research has mostly focused on the adverse consequences of screen media, we aim to depict both the negative and the positive influences of screen usage. To provide a more nuanced portrait of the potential benefits and harms of screen use, we examine how consequences of media use vary according to the content of media (ex., educational, violent), context (ex., using screens during mealtimes), and the nature (ex., passive vs active use) of child screen use. Our review supports existing screen time guidelines and recommendations and suggests that media content, the context of use, and the nature of child use, as well as the parent's own screen use, be considered clinically. Future research should seek to clarify how these dimensions jointly contribute to child screen use profiles and associated consequences. Finally, child sex, behavioral/temperamental difficulties, and family adversity appear to contribute to child screen use and its consequences and should be considered in future research. Suggestions for harm-reduction approaches are discussed.

The Role of Talking Faces in Infant Language Learning: Mind the Gap between Screen-Based Settings and Real-Life Communicative Interactions

Over the last few decades, developmental (psycho) linguists have demonstrated that perceiving talking faces audio-visually is important for early language acquisition. Using mostly well-controlled and screen-based laboratory approaches, this line of research has shown that paying attention to talking faces is likely to be one of the powerful strategies infants use to learn their native(s) language(s). In this review, we combine evidence from these screen-based studies with another line of research that has studied how infants learn novel words and deploy their visual attention during naturalistic play. In our view, this is an important step toward developing an integrated account of how infants effectively extract audiovisual information from talkers' faces during early language learning. We identify three factors that have been understudied so far, despite the fact that they are likely to have an important impact on how infants deploy their attention (or not) toward talking faces during social interactions: social contingency, speaker characteristics, and task- dependencies. Last, we propose ideas to address these issues in future research, with the aim of reducing the existing knowledge gap between current experimental studies and the many ways infants can and do effectively rely upon the audiovisual information extracted from talking faces in their real-life language environment.

Language in educational apps for pre-schoolers. A comparison of grammatical constructions and psycholinguistic features in apps, books and child directed speech

Language in touchscreen apps could be useful as an additional source of children's language input, alongside child directed speech (CDS) and books. Here we performed the first analysis of language in apps, as compared with books and CDS. We analysed language in 18 of the most popular educational apps targeting pre-schoolers and compared their language content to children's books and CDS with respect to types of constructions and psycholinguistic features of words. We found that apps contained lower frequency words and had lower lexical diversity compared to CDS, and shorter utterances compared to books. Apps may thus provide an enriched supplementary form of input for young children, due to containing less frequent words. However, apps do not expose children to a high proportion of questions and complex sentences, both of which are crucial for supporting child's development of structurally rich constructions.

Curiosity constructs communicative competence through social feedback loops

One of the most important challenges for a developing infant is learning how best to allocate their attention and forage for information in the midst of a great deal of novel stimulation. We propose that infants of altricial species solve this challenge by learning selectively from events that are contingent on their immature behavior, such as babbling. Such a contingency filter would focus attention and learning on the behavior of social partners, because social behavior reliably fits infants' sensitivity to contingency. In this way a contingent response by a caregiver to an immature behavior becomes a source of learnable information - feedback - to the infant. Social interactions with responsive caregivers afford infants opportunities to explore the impacts of their immature behavior on their environment, which facilitates the development of socially guided learning. Furthermore, contingent interactions are opportunities to make and test predictions about the efficacy of their social behaviors and those of others. In this chapter, we will use prelinguistic vocal learning to exemplify how infants use their developing vocal abilities to elicit learnable information about language from their social partners. Specifically, we review how caregivers' contingent responses to babbling create information that facilitates infant vocal learning and drives the development of communication. Infants play an active role in this process, as their developing predictions about the consequences of their actions serve to further refine their allocation of attention and drive increases in the maturity of their vocal behavior.

Screen time and preschool children: Promoting health and development in a digital world

COVID-19 transformed the family media environment and spurred research on the effects of screen media exposure and use on young children. This update of a 2017 CPS statement re-examines the potential benefits and risks of screen media in children younger than 5 years, with focus on developmental, psychosocial, and physical health. Four evidence-based principles-minimizing, mitigating, mindfully using, and modelling healthy use of screens-continue to guide children's early experience with a rapidly changing media landscape. Knowing how young children learn and develop informs best practice for health care providers and early years professionals (e.g., early childhood educators, child care providers). Anticipatory guidance should now include child and family screen use in (and beyond) pandemic conditions.

Revisiting the video deficit in technology-saturated environments: Successful imitation from people, screens, and social robots

The "video deficit" is a well-documented effect whereby children learn less well about information delivered via a screen than the same information delivered in person. Research suggests that increasing social contingency may ameliorate this video deficit. The current study instantiated social contingency to screen-based information by embodying the screen within a socially interactive robot presented to urban Australian children with frequent exposure to screen-based communication. We failed to document differences between 22- to 26-month-old children's (N = 80) imitation of screen-based information embedded in a social robot and in-person humans. Furthermore, we did not replicate the video deficit with children imitating at similar levels regardless of the presentation medium. This failure to replicate supports the findings of a recent meta-analysis of video deficit research whereby there appears to be a steady decrease over time in the magnitude of the video deficit effect. We postulate that, should the video deficit effect be truly dwindling in effect size, the video deficit may soon be a historical artifact as children begin perceiving technology as relevant and meaningful in everyday life more and more. This research finds that observational-based learning material can be successfully delivered in person, via a screen, or via a screen embedded in a social robot.

Language Experience during Infancy Predicts White Matter Myelination at Age 2 Years

Parental input is considered a key predictor of language achievement during the first years of life, yet relatively few studies have assessed the effects of parental language input and parent-infant interactions on early brain development. We examined the relationship between measures of parent and child language, obtained from naturalistic home recordings at child ages 6, 10, 14, 18, and 24 months, and estimates of white matter myelination, derived from quantitative MRI at age 2 years (mean = 26.30 months, SD = 1.62, N = 22). Analysis of the white matter focused on dorsal pathways associated with expressive language development and long-term language ability, namely, the left arcuate fasciculus (AF) and superior longitudinal fasciculus (SLF). Frequency of parent-infant conversational turns (CT) uniquely predicted myelin density estimates in both the AF and SLF. Moreover, the effect of CT remained significant while controlling for total adult speech and child speech-related utterances, suggesting a specific role for interactive language experience, rather than simply speech exposure or production. An exploratory analysis of 18 additional tracts, including the right AF and SLF, indicated a high degree of anatomic specificity. Longitudinal analyses of parent and child language variables indicated an effect of CT as early as 6 months of age, as well as an ongoing effect over infancy. Together, these results link parent-infant conversational turns to white matter myelination at age 2 years, and suggest that early, interactive experiences with language uniquely contribute to the development of white matter associated with long-term language ability.SIGNIFICANCE STATEMENT Children's earliest experiences with language are thought to have profound and lasting developmental effects. Recent studies suggest that intervention can increase the quality of parental language input and improve children's learning outcomes. However, important questions remain about the optimal timing of intervention, and the relationship between specific aspects of language experience and brain development. We report that parent-infant turn-taking during home language interactions correlates with myelination of language related white matter pathways through age 2 years. Effects were independent of total speech exposure and infant vocalizations and evident starting at 6 months of age, suggesting that structured language interactions throughout infancy may uniquely support the ongoing development of brain systems critical to long-term language ability.

Should I follow your virtual gaze? Infants' gaze following over video call

From 10 months of age, human infants start to understand the function of the eyes in the looking behavior of others to the point where they preferentially orient toward an object if the social partner has open eyes rather than closed eyes. Thus far, gaze following has been investigated in controlled laboratory paradigms. The current study investigated this early ability using a remote live testing procedure, testing infants in their everyday environment while manipulating whether the experimenter could or could not see some target objects. A total of 32 11- and 12-month-old infants' looking behavior was assessed, varying the experimenter's eye status condition (open eyes vs closed eyes) in a between-participant design. Results showed that infants followed the gaze of a virtual social partner and that they preferentially followed open eyes rather than closed eyes. These data generalize past laboratory findings to a noisier home environment and demonstrate gaze processing capacities of infants to a virtual partner interacting with the participants in a live setup.

Symbolic and deictic gestures as a tool to promote parent-child communication in the context of hearing loss: A systematic review

BACKGROUND

Language and communication outcomes in children with congenital sensorineural hearing loss (cSNHL) are highly variable, and some of this variance can be attributed to the quantity and quality of language input. In this paper, we build from the evidence that human language is inherently multimodal and positive scaffolding of children's linguistic, cognitive, and social-relational development can be supported by Parent Centered Early Interventions (PCEI), to suggest that the use of gestures in these interventions could be a beneficial approach, yet scarcely explored.

AIMS AND METHODS

This systematic review aimed to examine the literature on PCEI focused on gestures (symbolic and deictic) used to enhance the caregiver-child relationship and infant's language development, in both typically and atypically developing populations. The systematic review was conducted following the PRISMA guidelines for systematic reviews and meta-analyses. From 246 identified studies, 8 met PICO inclusion criteria and were eligible for inclusion. Two reviewers screened papers before completing data extraction and risk of bias assessment using the RoB2 Cochrane scale.

RESULTS

Included studies measured the effect of implementing symbolic or deictic gestures in daily communication on the relational aspects of mother/parent-child interaction or on language skills in infants. The studies indicate that gesture-oriented PCEI may benefit deprived populations such as atypically developing children, children from low-income families, and children who, for individual reasons, lag behind their peers in communication.

CONCLUSIONS

Although gesture-oriented PCEI appear to be beneficial in the early intervention for atypically developing populations, this approach has been so far scarcely explored directly in the context of hearing loss. Yet, symbolic gestures being a natural part of early vocabulary acquisition that emerges spontaneously regardless of hearing status, this approach could represent a promising line of intervention in infants with cSNHL, especially those with a worse head start.

Deaf Children's Engagement with American Sign Language-English Bilingual Storybook Apps

Design features of American Sign Language (ASL)-English bilingual storybook apps on the tablet computers, based on learning research, are intended to facilitate independent and interactive learning of English print literacy and of ASL skill among young learners. In 2013, the Science of Learning Center on Visual Language and Visual Learning introduced the first in a series of storybook apps for the iPad based on literacy and reading research. The current study, employing a sample of signing deaf children examined children's self-motivated engagement with the various design features presented in the earliest of the apps, The Baobab, and analyzed the relationships of engagement with ASL skill and age of first exposure to ASL, ASL narrative ability, and grade-appropriate English reading ability. Results indicated a robust level of engagement with the app, and a relationship between app pages specifically targeting reading and early exposure and skill levels in ASL. No evidence of relationships between narrative and vocabulary skills and app reading engagement was found. Topics for future research, and strategies for app improvement are discussed.

Face-to-face contact during infancy: How the development of gaze to faces feeds into infants' vocabulary outcomes

Infants acquire their first words through interactions with social partners. In the first year of life, infants receive a high frequency of visual and auditory input from faces, making faces a potential strong social cue in facilitating word-to-world mappings. In this position paper, we review how and when infant gaze to faces is likely to support their subsequent vocabulary outcomes. We assess the relevance of infant gaze to faces selectively, in three domains: infant gaze to different features within a face (that is, eyes and mouth); then to faces (compared to objects); and finally to more socially relevant types of faces. We argue that infant gaze to faces could scaffold vocabulary construction, but its relevance may be impacted by the developmental level of the infant and the type of task with which they are presented. Gaze to faces proves relevant to vocabulary, as gazes to eyes could inform about the communicative nature of the situation or about the labeled object, while gazes to the mouth could improve word processing, all of which are key cues to highlighting word-to-world pairings. We also discover gaps in the literature regarding how infants' gazes to faces (versus objects) or to different types of faces relate to vocabulary outcomes. An important direction for future research will be to fill these gaps to better understand the social factors that influence infant vocabulary outcomes.

Screen Time of Preschool-Aged Children and Their Mothers, and Children's Language Development

Although children’s increased screen time has been found to associate with poorer language development, it is open to question which part of language ability screen time specifically associates with. Our aim was to examine the association between children’s screen time (alone and together with a parent), mothers’ screen time, and the different domains of children’s language skills. Mothers reported their children’s (N = 164, aged 2.5 to 4.1 years) screen time and their own on a weekday and a day off. Children’s lexical, phonological, morphological, receptive, and general language abilities were measured using validated tests. The connections between children’s and mothers’ screen time and children’s language skills were analyzed using correlation analyses and linear regression models. The more the children used screen time alone, or the greater the amount of the mothers’ screen time, the weaker the children’s lexical and general language abilities when the children’s age, maternal education level, and birth order were controlled for. We also found cumulative, negative links to the children’s lexical and general language abilities when the amount of their screen time alone and the amount of the mothers’ screen time were simultaneously included in the regression model. The results suggest that it is important to restrict both children’s screen time spent alone and mothers’ screen time.

Implications of video chat use for young children's learning and social-emotional development: Learning words, taking turns, and fostering familial relationships

Parents of young children use video chat differently than other screen media, paralleling expert recommendations (e.g., American Academy of Pediatrics Council on Communications and Media, 2016), which suggest that video chat, unlike other screen media, is acceptable for use by children under 18 months. Video chat is unique among screen media in that it permits contingent (time-sensitive and content-sensitive) social interactions. Contingent social interactions take place between a child and a partner (dyadic), with objects (triadic), and with multiple others (multi-party configurations), which critically underpin development in multiple domains. First, we review how contingent social interaction may underlie video chat's advantages in two domains: for learning (specifically learning new words) and for social-emotional development (specifically taking turns and fostering familial relationships). Second, we describe constraints on video chat use and how using chat with an active adult (co-viewing) may mitigate some of its limitations. Finally, we suggest future research directions that will clarify the potential advantages and impediments to the use of video chat by young children.

The Development of a Parental Questionnaire (QQ-MediaSEED) on Bilingual Children's Quantity and Quality of Digital Media Use at Home

The quantity and quality of children's digital screen media exposure is an emerging area of early childhood studies because of its strong social relevance, and this has been particularly true since the COVID-19 pandemic. The few existing parental questionnaires on children's digital screen media exposure mainly focus on monolingual children's media habits and address either the quantity or quality of children's media exposure. Inspired by the existing instruments, the current study introduces a new parental questionnaire to comprehensively assess the duration, frequency, content, design, and use of bilingual children's digital screen media exposure at home, before and since the COVID-19 pandemic. Focus group discussions and the first wave of our data collection on 141 3-6 years old Singaporean bilingual children indicate good face validity and internal consistency of the parental questionnaire. Our results reveal substantial differences in children's quantity and quality of daily digital screen media exposure, as well as the discrepancies in their digital media habits between English and their mother tongue languages, before and since the COVID-19 pandemic.

Effects of screen exposure on young children's cognitive development: A review

The past decade has witnessed a rapid increase in the use of screen media in families, and infants are exposed to screens at younger ages than ever before. The objective of this review is twofold: (1) to understand the correlates and demographic factors determining exposure to screens, including interactive screens, when available, and (2) to study the effects of watching screens and using touchscreens on cognitive development, during the first 3 years of life. We argue that the effects of screen viewing depend mostly on contextual aspects of the viewing rather than on the quantity of viewing. That context includes the behavior of adult caregivers during viewing, the watched content in relation to the child's age, the interactivity of the screen and whether the screen is in the background or not. Depending on the context, screen viewing can have positive, neutral or negative effects on infants' cognition.

Raising the Child-Do Screen Media Help or Hinder? The Quality over Quantity Hypothesis

Screen media are ubiquitous in human life across all age, cultural and socioeconomic groups. The ceaseless and dynamic growth of technological possibilities has given rise to questions regarding their effect on the well-being of children. Research in this area largely consists of cross-sectional studies; experimental and randomized studies are rare, which makes drawing causative conclusions difficult. However, the prevailing approach towards the use of screen media by children has focused on time limitations. The emerging evidence supports a more nuanced perspective. It appears that the older the child, the more important how the screen media are used becomes. Concentrating on the quality of the screen, time has become increasingly relevant in the recent COVID-19 pandemic, which necessitated a transfer of educational and social functioning from real-life to the digital world. With this review, we aimed at gathering current knowledge on the correlations of different screen media use and development outcomes, as well as providing an overview of potential benefits that new technologies may provide to the pediatric population. To summarize, if one cannot evade screen time in children, how can we use it for children's maximum advantage?

Presence at a distance: Video chat supports intergenerational sensitivity and positive infant affect during COVID-19

COVID-19 disrupted infant contact with people beyond the immediate family. Because grandparents faced higher COVID-19 risks due to age, many used video chat instead of interacting with their infant grandchildren in person. We conducted a semi-naturalistic, longitudinal study with 48 families, each of whom submitted a series of video chats and surveys, and most (n = 40) also submitted a video of an in-person interaction. Families were mostly highly-educated, White/Caucasian, and lived between 1 and 2700 miles apart. We used multilevel models to examine grandparents' and parents' sensitivity during video chat across time (centered at February 1, 2021, the approximate date of vaccine availability). Grandparent video chat sensitivity changed as a function of date and parent sensitivity. Parent sensitivity changed as a function of date, grandparent sensitivity, and geographic distance. We then modeled infants' affective valence during video chat and in-person interactions with their grandparents, which was only predicted by grandparent sensitivity, not modality or other factors. This study demonstrates that caregivers were sensitive toward infants during video chat interactions despite fluctuations in family stress and reduced in-person contact during COVID-19 and that grandparent sensitivity predicted positive infant affect during both video chat and in-person interactions.

From social contingency to verbal reference: A constructivist hypothesis

In the first year of life, infants' word learning is slow, laborious, and requires repeated exposure to word-referent co-occurrences. In contrast, by 14-18 months, infants learn words from just a few labeling events, use joint attention and eye gaze to decipher word meaning, and begin to use speech to communicate about absent things. We propose that this remarkable advancement in word learning results from attaining a referential understanding of words-that words are linked to mental representations and used intentionally to communicate about real-world entities. We suggest that verbal reference is supported by codeveloping conceptual, social, representational, and statistical learning capacities. We also propose that infants' recognition of this tri-directional link between words, referents, and mental representations is enabled by their experience participating in and observing socially contingent interactions. Understanding verbal reference signals a qualitative shift in infants' word learning. This shift enables infants to bootstrap word meanings from syntax and semantics, learn novel words and facts from nonostensive communication, and make inferences about speakers' epistemic competence based on their language production. In this paper, we review empirical findings across multiple facets of infant cognition and propose a novel developmental theory of verbal reference. Finally, we suggest new directions of empirical research that may provide stronger and more direct evidence for our theory and contribute to our understanding of the development of verbal reference and language-mediated learning in infancy and beyond.

The map trap: Why and how word learning research should move beyond mapping

A pervasive goal in the study of how children learn word meanings is to explain how young children solve the mapping problem. The mapping problem asks how language learners connect a label to its referent. Mapping is one part of word learning, however, it does not reflect other critical components of word meaning construction, such as the encoding of lexico-semantic relations and socio-pragmatic context. In this paper, we argue that word learning researchers' overemphasis of mapping has constrained our experimental paradigms and hypotheses, leading to misconceived theories and policy interventions. We first explain how the mapping focus limits our ability to study the richness and complexity of what infants and children learn about, and do with, word meanings. Then, we describe how our focus on mapping has constrained theory development. Specifically, we show how it has led to (a) the misguided emphasis on referent selection and ostensive labeling, and (b) the undervaluing of diverse pathways to word knowledge, both within and across cultures. We also review the consequences of the mapping focus outside of the lab, including myopic language learning interventions. Last, we outline an alternative, more inclusive approach to experimental study and theory construction in word learning research.

Infant behavioural effects of smartphone interrupted parent-infant interaction

Infants are vulnerable to changes in the dyadic synchrony with their caregivers, as demonstrated in numerous experiments employing the still-face paradigm. The sudden lack of attunement causes infant stress reactions and the still-face literature have suggested potential long-term costs of this in terms of development of social, emotional and cognitive skills. Acknowledging the rapid technological development accompanied by altered practices in the parent-infant interaction, the current study investigates infant behavioural reactions in a similar experimental paradigm, manipulating parental responsiveness and sensitivity in a slightly different manner. In the current study, the parent interrupts the ongoing interaction, simulating occupation with a smartphone, rather than making a 'still-face'. In a cross-sectional design, infants of six, nine and twelve months display increased levels of protest behaviour in response to the interrupted interaction with their parent, together with lowered levels of positive engagement and social monitoring, suggesting similar behavioural responses as the still-face effect. Implications for infant social and emotional development, as well as for mindful tech habits are discussed.

Semantic Contingency of Maternal Verbal Input Directed at Very Preterm and Full-Term Children

Several studies have testified to the importance of a responsive linguistic input for children’s language acquisition and development. In particular, maternal use of expansions, imitations, interpretations, and labels has been shown to promote both children’s language comprehension and production. From this perspective, the present study examined the semantically contingent linguistic input addressed to very preterm children’s comparing it to that directed to full-term children observed during a semi-structured play session when the children were 24 months of age. The relationships between maternal contingent utterances and children’s communicative repertoires were also investigated. The main results showed that mothers of full-term children produced a higher proportion of semantically contingent utterances than those of very preterm children; moreover, this variable was associated with children’s more advanced communicative-linguistic outcomes. Overall, this study supports the interdependence between mothers’ use of certain linguistic strategies and children’s communicative-linguistic repertoire, extending this evidence to children born very preterm and suggesting the importance of considering the semantic contingency aspect of child-directed speech to support the communicative and linguistic development of these children.

What Do Preschool Teachers and Parents Think about the Influence of Screen-Time Exposure on Children’s Development? Challenges and Opportunities

Children’s exposure to screens has been increasing in recent years and so has the concern about its impact on children’s development. This study aims to analyze preschool teachers’ and parents’ views on the influence of screen-time exposure on children’s development. Semi-structured interviews with preschool teachers (n = 9), as well as data from a previous quantitative study, based on an online questionnaire applied to parents of children in preschool (n = 266) were used for data collection. For this study, eminently of qualitative nature, the following dimensions were analyzed: children’s habits of exposure to screens at home, changes in children’s play habits at school, strategies/methodologies used by preschool teachers, use of technologies at school and children’s language development. The results from the study with parents show that screen-time exposure of children is between 1 h to 2 h of television per day, mostly to watch cartoons. Parents also report that most of the children use vocabulary in other languages at home. Most preschool teachers agreed that children are changing their play habits and mainly their behaviors and attitudes, influenced by screen-time exposure. They believe that language development is also changing, mentioning more language problems in children. Changes in pedagogic strategies and specialized training on educational technology are needed to get closer to children’s interests.

Correlates of parental knowledge about smartphone exposure among young children

BACKGROUND

Unhealthy smartphone habits use can impair the health of young children. Smartphone use among young children is affected by several factors of which the most important is parental knowledge pertains to smartphone exposure among young children. In Jordan, no studies have focused on this factor.

METHOD

A nation-wide cross-sectional survey was distributed to parents of children aged <6 years to assess parental knowledge of smartphone exposure among young children and examine its correlates in Jordan. An online self-reporting questionnaire was administered via Survey Monkey and posted on social media platforms in June 2020.

RESULTS

A total of 2,781 Jordanian parents completed the survey. During the pandemic the daily hours of Smartphone use among children were significantly higher than prior the coronavirus-2019 (COVID-19) pandemic (2.12 vs. 1.7 h). More than half the children exceeded the recommended daily hours of use. These results were positively associated with increased smartphone use among parents. Overall, the parents proved knowledgeable regarding the effects of excessive smartphone exposure on the health of their children. However, a knowledge deficit was evident in two areas: parental controls on smartphone and safe levels of infant smartphone exposure. The mothers possessed a significantly higher level of knowledge than the fathers.

CONCLUSION

The results suggest that, in the context Jordan, increasing parental knowledge has the potential to reduce smartphone exposure among young children. Awareness campaigns are needed to enhance parental knowledge of smartphone exposure among young children and the use of parental controls on smartphones.
