Co-viewing supports toddlers' word learning from contingent and noncontingent video

School-age children are more skeptical of inaccurate robots than adults

We expect children to learn new words, skills, and ideas from various technologies. When learning from humans, children prefer people who are reliable and trustworthy, yet children also forgive people's occasional mistakes. Are the dynamics of children learning from technologies, which can also be unreliable, similar to learning from humans? We tackle this question by focusing on early childhood, an age at which children are expected to master foundational academic skills. In this project, 168 4-7-year-old children (Study 1) and 168 adults (Study 2) played a word-guessing game with either a human or robot. The partner first gave a sequence of correct answers, but then followed this with a sequence of wrong answers, with a reaction following each one. Reactions varied by condition, either expressing an accident, an accident marked with an apology, or an unhelpful intention. We found that older children were less trusting than both younger children and adults and were even more skeptical after errors. Trust decreased most rapidly when errors were intentional, but only children (and especially older children) outright rejected help from intentionally unhelpful partners. As an exception to this general trend, older children maintained their trust for longer when a robot (but not a human) apologized for its mistake. Our work suggests that educational technology design cannot be one size fits all but rather must account for developmental changes in children's learning goals.

Look at Grandma! Joint visual attention over video chat during the COVID-19 pandemic

Social interactions are crucial for many aspects of development. One developmentally important milestone is joint visual attention (JVA), or shared attention between child and adult on an object, person, or event. Adults support infants' development of JVA by structuring the input they receive, with the goal of infants learning to use JVA to communicate. When family members are separated from the infants in their lives, video chat sessions between children and distant relatives allow for shared back-and-forth turn taking interaction across the screen, but JVA is complicated by screen mediation. During video chat, when a participant is looking or pointing at the screen to something in the other person's environment, there is no line of sight that can be followed to their object of focus. Sensitive caregivers in the remote and local environment with the infant may be able to structure interactions to support infants in using JVA to communicate across screens. We observed naturalistic video chat interactions longitudinally from 50 triads (infant, co-viewing parent, remote grandmother). Longitudinal growth models showed that JVA rate changes with child age (4 to 20 months). Furthermore, grandmother sensitivity predicted JVA rate and infant attention. More complex sessions (sessions involving more people, those with a greater proportion of across-screen JVA, and those where infants initiated more of the JVA) resulted in lower amounts of JVA-per-minute, and evidence of family-level individual differences emerged in all models. We discuss the potential of video chat to enhance communication for separated families in the digital world.

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.

The quality of caregiver-child interaction is predicted by (caregivers' perception of) their child's interests

This current study examines the extent to which children's interests and caregivers' sensitivity to their children's interests are associated with the quality of caregiver-child interaction, and subsequent learning. Eighty-one caregiver-child dyads (24-30-month old children) completed an online shared book-reading task where caregivers and children read two e-books with pictures and descriptions of objects from different categories-one previously determined to be of low and one of high interest to the child (with one novel word-object mapping introduced in each book). We also obtained separate behavioural indices of children's interests and children's later recognition of newly introduced word-object mappings. Our findings highlight that the quality of caregiver-child interaction is predicted by children's interests and caregivers' perception of children's interests, although we find only limited overlap between our behavioural indices of children's interests and caregiver perception of children's interests. Neither of these factors predicted later novel word recognition. Thus, while the dynamics between higher quality of caregiver-child interaction, children's interests and learning remain inconclusive, caregivers and children appear to be more attentive, enthusiastic and engaged in reading about topics that (caregivers believe) interest the child. Furthermore, learning in itself seems to be successful, regardless of factors involved, through the mere task of shared book reading.

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.

The Relationship between Language and Technology: How Screen Time Affects Language Development in Early Life-A Systematic Review

Screen time refers to the amount of time a child is exposed to a screen, that is, television, computer, smartphone, or any other digital medium. Prolonged screen time in the first years of life may affect a child's cognitive abilities, especially language acquisition. A systematic review was conducted, following the PRISMA-P guidelines, with the aim to explore the available literature relating to the impact of screen time on children's language development. This review identified 18 articles. The articles reviewed showed that prolonged screen time and exposure to screens in the first 2 years of life can negatively affect language development and communication skills, in terms of comprehension and vocabulary range. In addition, overexposure to screens in the early years can affect overall cognitive development, especially attention to environmental stimuli, social experiences, problem solving, and communication with others, e.g., the alternance of rhythms and roles in a conversation. In conclusion, our systematic review supports the idea that preschool screen time has negative effects on children's cognitive and language development. Television seems to be the medium most detrimental to children's skills, as it is used in a passive manner and is often characterised by language and content that do not suit the child's processing mode. Future studies should increasingly focus on the digital media that children possess at an early age, such as mobile phones and tablets, and on how children relate to the online world, such as social networks.

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.

The Influence of Shyness on Language Assessment

PURPOSE

The goal of this study is to examine how shyness affects a child's performance on language assessments that vary in sociability. We hypothesized that accuracy on language tasks would be driven by shyness such that shyer children would perform better on nonsociable tasks compared to sociable tasks.

METHOD

The procedures followed a quasi-experimental design. One hundred twenty-two participants, ages 17-42 months and varying in their temperament, each underwent a series of three language tasks. The order of tasks was randomized, and each task varied in the social interaction required: a looking task, a pointing task, and a production task. Data were collected via Zoom, and parents reported their child's shyness level via the Early Child Behavior Questionnaire.

RESULTS

Shyness was compared with participants' accuracy across the three tests while controlling for age and vocabulary percentile. There were significant differences in children's performance across the tasks, with respect to shyness. Shyer children performed worse on the production task compared to less shy children. All children did well on the pointing task regardless of shyness level, but performance was more nuanced on the looking task such that shyer children were at times more accurate but also less likely to respond in general.

CONCLUSIONS

As shown by these results, shyer and less shy children respond differentially to methods of language assessment that vary in sociability. It is important for clinicians to acknowledge shyness when choosing an appropriate assessment of children's language. Future direction includes assessing performance on standardized assessments.

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.

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.

Impact of the COVID-19 pandemic on the well-being of preschoolers: A parental guide

Unexpected changes brought about by the coronavirus disease 2019 (COVID-19) have affected humans worldwide. This review attempts to address major parental concerns about the development of preschool-aged children during the pandemic from the perspectives of neuropsychology, consultation, and motor development for preschoolers aged 2–5 years.

Methods

A total of 273 articles including original data, review articles, national and regional perspectives, government websites, and commentaries were considered in this review, of which 117 manuscripts were excluded because they were unrelated to children, adolescents, or COVID -19 pandemic/upper respiratory infections. A total of 156 manuscripts were included after reading the abstract and entire article.

Results

Telehealth could be an effective tool for addressing cognitive and emotional challenges that arise during the pandemic. Online consultations are highlighted for nutritional guidelines and to overcome problems that parents face when caring for children in difficult times. Outdoor activities using sanitisers, proper cleanliness, and following standard operating procedures are recommended. Parental preoccupation with media should be avoided. Interpretation: Many preschoolers show delays in reaching their developmental milestones, and the pandemic has increased parents' concerns, as access to practitioners is limited. Therefore, parents should be encouraged to undergo neuropsychological consultations whenever necessary. This study emphasises important strategies to ensure that children's development is minimally affected while staying in the confined environment of their homes. This study serves as a new guide for parents, as they raise young children in the new normal. Parents should undergo basic yearly physical, neuropsychological, nutritional, and speech checkups.

Patterns of preschool children's screen time, parent-child interactions, and cognitive development in early childhood: a pilot study

BACKGROUND

The primary objective of this study was to explore the feasibility of a virtual study protocol for a future longitudinal study, including recruitment, study measures, and procedures. The secondary objective was to examine preliminary hypotheses of associations, including 1) the correlations between total duration and patterns of screen time and cognitive development, and 2) the differences in quality of parent-child interactions for two screen-based tasks and a storybook reading task.

METHODS

Participants included 44 children aged 3 years and their parents from Edmonton, Alberta and surrounding areas. Children's screen time patterns (i.e., type, device, content, context) were parental-reported using a 2-week online daily diary design. Children's cognitive development (i.e., working memory, inhibitory control, self-control, and language) was measured virtually through a recorded Zoom session. Parent-child interactions during three separate tasks (i.e., video, electronic game, and storybook reading) were also measured virtually through a separate recorded Zoom session (n = 42). The quality of the interactions was determined by the Parent-Child Interaction System (PARCHISY). Descriptive statistics, Intra-class correlations (ICC), Spearman's Rho correlations, and a one-way repeated measures ANOVA with a post-hoc Bonferroni test were conducted.

RESULTS

All virtual protocol procedures ran smoothly. Most (70%) participants were recruited from four 1-week directly targeted Facebook ads. High completion rates and high inter-rater reliability in a random sample (Diary: 95% for 13/14 days; Cognitive development: 98% 3/4 tests, ICC > 0.93; Parent-child interactions: 100% for 3 tasks, Weighted Kappa ≥ 0.84) were observed for measures. Across cognitive development outcomes, medium effect sizes were observed for five correlations, with positive correlations observed with certain content (i.e., educational screen time) and negative associations observed for total screen time and certain types (show/movie/video viewing) and contexts (i.e., co-use). Medium and large effect sizes were observed for the differences in parent-child interaction quality between the three tasks.

CONCLUSIONS

The virtual study protocol appeared feasible. Preliminary findings suggest it may be important to go beyond total duration and consider type, content, and context when examining the association between screen time and cognitive development. A future longitudinal study using this virtual protocol will be conducted with a larger and more generalizable sample.

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. This article is categorized under: Linguistics > Language Acquisition Psychology > Learning Cognitive Biology > Social Development.

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.

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.

Children's screen use and school readiness at 4-6 years: prospective cohort study

Background

The primary aim of this study was to determine if screen use in early childhood is associated with overall vulnerability in school readiness at ages 4 to 6 years, as measured by the Early Development Instrument (EDI). Secondary aims were to: (1) determine if screen use was associated with individual EDI domains scores, and (2) examine the association between screen use and EDI domains scores among a subgroup of high screen users.

Methods

This prospective cohort study was carried out using data from young children participating in a large primary care practice-based research network in Canada. Logistic regression analyses were run to investigate the association between screen use and overall vulnerability in school readiness. Separate linear regression models examined the relationships between children’s daily screen use and each separate continuous EDI domain.

Results

A total of 876 Canadian participants participated in this study. Adjusted logistic regression revealed an association between increased screen use and increased vulnerability in school readiness (p = 0.05). Results from adjusted linear regression demonstrated an association between higher screen use and reduced language and cognitive development domain scores (p = 0.004). Among high screen users, adjusted linear regression models revealed associations between increased screen use and reduced language and cognitive development (p = 0.004) and communication skills and general knowledge domain scores (p = 0.042).

Conclusions

Screen use in early childhood is associated with increased vulnerability in developmental readiness for school, with increased risk for poorer language and cognitive development in kindergarten, especially among high users.

The influence of screen time on children's language development: A scoping review

Background

An exponential increase in screen time amongst children and adults, has given rise to a plethora of studies exploring the influences that this exposure may have on children’s development.

Objectives

This review is specifically concerned with understanding the influence of screen time on children’s language development.

Method

A scoping review was conducted to explore the available literature relating to the impact of screen time on children’s language development. The scoping review was based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews (PRISMA-ScR) framework and the Joanna Briggs Institute (JBI) framework. The data were analysed using thematic content analysis.

Results

This review identified 12 articles. It made an argument for the multifactorial relationship between screen time and language development, given the associated positive and negative effects. The results revealed core themes such as the influence of screen time being dependent on various factors and the diverse effects of screen time on children’s language development, with the inclusion of parents’ monitoring of and participation in viewing, playing a vital role in language development.

Conclusion

The review indicated that an increase in the amount of screen time and an early age of onset of viewing have negative effects on language development, with older age of onset of viewing showing some benefits. Video characteristics, content and co-viewing also influences language development. This study demonstrates that the negative influences of screen time appear to outweigh the positive influences.

Parent Verbalizations and Toddler Responses With Touchscreen Tablet Nursery Rhyme Apps

OBJECTIVES

In some studies, parents and toddlers verbalize less when engaging with a tablet versus a print book. More needs to be known regarding child contributions to specific parent verbalizations. We examined parent-toddler contingent interactions with tablet applications versus print books, as well as moderators of these associations.

METHODS

We conducted a laboratory-based, within-subjects counterbalanced study of 72 parent-toddler dyads engaging with a nursery rhyme application (with enhanced + autonarration [E+A] and enhanced formats) and print book. We coded parent verbalizations (eg, dialogic, nondialogic) and proportions of child responses to these in 5-second epochs. Poisson regressions were used to analyze within-subjects variance by tablet or print format. We tested effect modification by child emotion regulation and home media practices.

RESULTS

Children responded more to parent overall (print 0.38; E+A 0.31, P = .04; enhanced 0.11, P = .01), dialogic (print 0.21; E+A 0.13, P = .04; enhanced 0.1, P = .02), and nondialogic (print 0.45; E+A 0.27, P < .001; enhanced 0.32, P < .001) verbalizations during print book versus tablet. Stronger child emotion regulation, greater frequency of co-viewing, and instructive practices moderated associations such that differences between conditions were no longer significant for some parent verbalizations and child responses.

CONCLUSIONS

Parent-toddler reciprocal verbal interactions occurred less frequently with tablet versus print book use. Child emotion regulation and parent home media practices moderated some of these associations. Pediatricians may wish to promote co-viewing and instructive media practices but may also consider that child emotion regulation may determine response to interactive tablet design.

Do Young Children of the "Selfie Generation" Understand Digital Photos as Representations?

In research from the 1990s, very young children failed to use pictures as representations of real events. Today, many children in the "selfie generation" are constantly photographed by their families using smartphones. While family photos are created, children are exposed to live video on the phone screen that, with a screen touch, becomes an instant photo. Children also revisit these family photos in the phone's photo library. This study explored whether toddlers growing up around smartphone photography are more successful in applying information from a photo to a real event, compared to children in the earlier research. Sixty 2-year-old children (23.0 to 26.2 months; M = 24.5 months) were asked to use pictures of a toy's hiding place (printed photographs or digital photos on an iPhone) to search for the hidden toy in 5 conditions. Toddlers were not successful with printed or digital images, whether the digital photos were accessed from the phone photo library or the researcher took the photos during the study. However, after children collaborated with the researcher to create digital photos to help an adult confederate, they were significantly more likely to use photos themselves to solve the search task. Children who experienced this scaffolding with printed photos were somewhat more successful than those without training. As with traditional symbolic media, young children's learning from emerging technologies needs the support of an adult who co-views the medium and helps clarify the symbolic relation between screen and world.

Can infants use video to update mental representations of absent objects?

Before their second birthday, infants can update their knowledge based on what someone tells them, but can they do so based on what a video shows them? The current study explored whether infants can update their representation of an absent object's properties after seeing a video of something happening to it, following seminal work showing that they can update their representation after being told about something happening to it (Ganea et al., 2007). It thus adapted an existing paradigm for testing infants' understanding of references to absent objects (using language) to investigate a different symbolic medium (video). Twenty-two-month-olds first played with a toy and later saw on video that the toy underwent a change in state while they were out of the room. Infants in the current study did not subsequently identify the toy based on this new information, whereas those in previous research did. Infants this age thus appear less likely to update their representation of an absent object's properties using video than using language. This result is consistent with the possibility that infants may understand the representational function of symbolic objects later in development than they understand the representational function of language. It also aligns with evidence of the video deficit in which infants learn less effectively from video than from firsthand experience.

Mobile technology usage in early childhood: Pre-COVID-19 and the national lockdown period in North Cyprus

COVID-19 has affected North Cyprus since the beginning of March 2020. On March 10^th 2020, the council of ministers in North Cyprus announced a lockdown and listed some restrictions to prevent the spread of the virus; schools and entertainment centres were closed, and children had to spend most of their day at home. This study aims to examine the use of mobile technology before and during the COVID-19 lockdown period by children aged three to six, based on parents' opinions. This is a descriptive study with a sample of 319 parents. Data and demographic information were collected with a questionnaire and analysed with SPSS (24.0). Comparing the duration of mobile technology device usage before the pandemic and during the lockdown period, an increase is evident, as expected. Of note, when compared to the pre-pandemic period, it is found that there is a decrease in the rate of mobile technology device usage for video viewing during the lockdown period. The findings also suggest that children mostly first experienced mobile technology devices in some way before 36 months of age. This study has determined that most children do not have their own mobile technology device.

Learning to learn from video? 30-month-olds benefit from continued use of supportive scaffolding

Young children struggle to learn new words presented on video, but adult co-viewers can support them by providing scaffolds that explicitly connect the video and real world. In this study, we asked whether scaffolding facilitates children's symbolic understanding of the video, such that they will subsequently transfer labels from video to real referents. Sixty-three 30-month-olds and 61 36-month-olds participated in a series of three word learning trials in one of three conditions. In the supportive condition, an in-person adult explicitly drew connections between each on-screen object and the corresponding real object in the room with the child. In the unsupportive condition, the in-person adult provided similar-length statements about the objects but did not draw connections between them. In the partial scaffold condition, the in-person adult provided the supportive scaffolds for the first two trials and the unsupportive version for the third trial. At 30 months, children selected the correct object on the third trial more often in the supportive than the unsupportive scaffold condition, and performance in the partial scaffold condition fell in between. At 36 months, performance on the third trial did not differ across conditions. The results showed that experiencing the scaffold twice was not enough to reliably support 30-month-olds in learning to think symbolically on the third trial; rather, they appeared to rely on the adult to connect the video image with its specific real-world referent. At 36 months, however, children did not rely on the adult scaffold to apply the video label to the real-world objects.

Communicative Environmental Factors Including Maternal Depression and Media Usage Patterns on Early Language Development

INTRODUCTION

From the ecological perspective of multifactorial causal mechanism, the communicative interaction environment has been less studied in early childhood which is the most sensitive phase for language development. We aimed to research simultaneous communicative environmental factors including maternal depression and media usage patterns in young children aged 1-3^1/2 years.

METHODS

One hundred and one participants were included in the study; fifty-one children with language delay as the case group and fifty children with typical development as the control group. Maternal depressive symptoms were evaluated by Beck Depression Inventory. The general development of each child was evaluated by Denver II Screening Test and Bayley-Third Edition. Language development was evaluated by the Preschool Language Scale-5. The questionnaire for the sociodemographic data and media usage patterns was prepared by the study team.

RESULTS

Maternal depression scores, duration of TV viewing, background TV were higher in the children with language delay and they started earlier using screen devices in comparison with the control group (p < 0.05). The total amount of interaction time and co-viewing were less in children with language delay and more parents intended to keep their children occupied by watching in the case group (p < 0.05). Mother care-giving (p = 0.002, OR = 5.80, CI 1.93-17.4) and absence of co-viewing (p = 0.000, OR = 9.46, CI 2.69-33.3) were the significant factors associated with language delay.

DISCUSSION

Young children with language delay were more exposed to communicative environmental risk factors than children with typical development. The integration of this perspective to child health care practices should be encouraged in early childhood.

Touchscreens for Whom? Working Memory and Age Moderate the Impact of Contingency on Toddlers' Transfer From Video

Toddlers exhibit poor transfer between video and real-world contexts. Contingently responsive video such as that found in touchscreen apps appears to assist transfer for some toddlers but not others. This study investigated the extent to which toddlers' working memory moderates the impact of contingency on toddler's transfer of learning from video. Toddlers (24–36 months; N = 134) watched a hiding event on either (a) contingent video that advanced only after touch input or (b) non-contingent video that proceeded automatically. Toddlers then searched for a corresponding object on a felt board. Additionally, toddlers' working memory (WM) was assessed. Findings indicate WM and age moderated the impact of contingency on transfer: Contingency decreased transfer in younger children while increasing transfer among older children. However, this was only true for children with relatively low WM. Contingency had little impact on transfer among children with relatively high WM, regardless of age. Results from this study suggest that WM is one specific moderator that predicts whether toddlers are likely to learn from contingent vs. non-contingent video, yet WM does not operate in isolation. Together, these findings underscore the importance of considering multiple child characteristics when identifying the optimal conditions for toddlers' learning from symbolic media.

2-Year-Olds Learning From 2D Media With and Without Parental Support: Comparing Two Forms of Joint Media Engagement With Passive Viewing and Learning From 3D

The study investigates to what degree two different joint media engagement (JME) strategies affect children’s learning from two-dimensional (2D)-media. More specifically, we expected an instructed JME strategy to be more effective than a spontaneous, non-instructed, JME strategy. Thirty-five 2-year old children saw a short video on a tablet demonstrating memory tasks together with a parent. The parents were randomized into two groups: One group (N = 17) was instructed to help their child by describing the actions they saw on the video while the other group (N = 18) received no specific instruction besides “do as you usually do.” The parents in the instructed group used significantly more words and verbs when supporting their child but both groups of children did equally well on the memory test. In a second step, we compared the performance of the two JME groups with an opportunistic comparison group (N = 95) tested with half of the memory tasks live and half of the tasks on 2D without any JME support. Results showed that the JME intervention groups received significantly higher recall scores than the no JME 2D comparison group. In contrast, the three-dimensional (3D) comparison group outperformed both JME groups. In sum, our findings suggest that JME as implemented here is more effective in promoting learning than a no JME 2D demonstration but less so than the standard 3D presentation of the tasks.

Preschoolers Benefit Equally From Video Chat, Pseudo-Contingent Video, and Live Book Reading: Implications for Storytime During the Coronavirus Pandemic and Beyond

During the unprecedented coronavirus disease (COVID-19) crisis, virtual education activities have become more prevalent than ever. One activity that many families have incorporated into their routines while at home is virtual storytime, with teachers, grandparents, and other remote adults reading books to children over video chat. The current study asks how dialogic reading over video chat compares to more traditional forms of book reading in promoting story comprehension and vocabulary learning. Fifty-eight 4-year-olds (M age = 52.7, SD = 4.04, 31 girls) were randomly assigned to one of three conditions (Video chat, Live, and Prerecorded). Across conditions, children were read the same narrative storybook by a female experimenter who used the same 10 scripted dialogic reading prompts during book reading. In the Video chat (n = 21) and Live conditions (n = 18), the experimenter gave the scripted prompts and interacted naturally and contingently, responding in a timely, relevant manner to children's behaviors. In the Prerecorded condition (n = 19), children viewed a video of an experimenter reading the book. The Prerecorded condition was pseudo-contingent; the reader posed questions and paused for a set period of time as if to wait for a child's response. After reading, children completed measures of vocabulary and comprehension. Results revealed no differences between conditions across six different outcome measures, suggesting that children comprehended and learned from the story similarly across book formats. Further, children in the three experimental conditions scored significantly higher on measures than children in a fourth condition (control) who had never read the book, confirming that children learned from the three different book formats. However, children were more responsive to the prompts in the Live and Video chat conditions than the Prerecorded condition, suggesting that children recognized that these interactions were contingent with their responses, a feature that was lacking in the Prerecorded condition. Results indicate that children can comprehend books over video chat, suggesting that this technology is a viable option for reading to children, especially during the current pandemic.

Mirror, Peephole and Video - The Role of Contiguity in Children's Perception of Reference in Iconic Signs

The present study looked at the extent to which 2-year-old children benefited from information conveyed by viewing a hiding event through an opening in a cardboard screen, seeing it as live video, as pre-recorded video, or by way of a mirror. Being encouraged to find the hidden object by selecting one out of two cups, the children successfully picked the baited cup significantly more often when they had viewed the hiding through the opening, or in live video, than when they viewed it in pre-recorded video, or by way of a mirror. All conditions rely on the perception of similarity. The study suggests, however, that contiguity – i.e., the perception of temporal and physical closeness between events – rather than similarity is the principal factor accounting for the results.

Influence of Mothers/Grandmothers Coviewing Cartoons With Children on Children's Viewing Experience

Watching cartoons is one important event in children’s early lives. This activity is highly influential on many factors, such as children’s cognitive and behavioral development. Some researchers believe that parents should coview cartoons with children to help them filter and distinguish useful content. However, intergenerational education is already common in China, and the influence of grandparents cannot be ignored. Because they are in different stages of life, the members of these two generations manifest great differences in parenting style, which may lead to differences in child development. Does this generational difference have differential effects on the children’s cartoon-viewing experience? We recruited 89 parents and grandparents and their kindergarten-aged children (approximately 5 years old) to participate in the study. The mothers or grandmothers were asked to coview a cartoon for approximately 7 min with their child, after which the child was asked questions about the cartoon-viewing experience. The results show the following: (1) compared with grandmothers, mothers generally think that cartoons have a very high influence on children’s physical and mental health (χ² = 8.83, p < 0.05), (2) mothers place more restrictions on the content of cartoons that their children view, whereas grandmothers’ attitudes are characterized by greater tolerance (χ² = 11.94, p < 0.01), and (3) in the case of coviewing with mothers, when the children are asked “why” questions about the cartoon-viewing experience questionnaire, they use more experience proofs to explain their answers than when they coview with grandmothers (χ² = 16.69, p < 0.01; χ² = 10.44, p < 0.05).

Toddlers' word learning through overhearing: Others' attention matters

In laboratory settings children are able to learn new words from overheard interactions, yet in naturalistic contexts this is often not the case. We investigated the degree to which joint attention within the overheard interaction facilitates overheard learning. In the study, 20 2-year-olds were tested on novel words they had been exposed to in two different overhearing contexts: one in which both interlocutors were attending to the interaction and one in which one interlocutor was not attending. Participants learned the new words only in the former condition, indicating that they did not learn when joint attention was absent. This finding demonstrates that not all overheard interactions are equally good for word learning; attentive interlocutors are crucial when learning words through overhearing.

Differences in Parent-Toddler Interactions With Electronic Versus Print Books

OBJECTIVES

Previous research has documented less dialogic interaction between parents and preschoolers during electronic-book reading versus print. Parent-toddler interactions around commercially available tablet-based books have not been described. We examined parent-toddler verbal and nonverbal interactions when reading electronic versus print books.

METHODS

We conducted a videotaped, laboratory-based, counterbalanced study of 37 parent-toddler dyads reading on 3 book formats (enhanced electronic [sound effects and/or animation], basic electronic, and print). We coded verbalizations in 10-second intervals for parents (dialogic, nondialogic, text reading, format related, negative format-related directives, and off task) and children (book related, negative, and off task). Shared positive affect and collaborative book reading were coded on a scale of 1 to 5 (5 = high). Proc Genmod and Proc Mixed analyzed within-subjects variance by book format.

RESULTS

Parents showed significantly more dialogic (print 11.9; enhanced 6.2 [P < .001]; basic 8.3 [P < .001]), text-reading (print 14.3; enhanced 10.6 [P = .003]; basic 14.4 [P < .001]), off-task (print 2.3; enhanced 1.3 [P = .007]), and total (29.5; enhanced 28.1 [P = .003]; basic 29.3 [P = .005]) verbalizations with print books and fewer format-related verbalizations (print 1.9; enhanced 10.0 [P < .001]; basic 8.3 [P < .001]). Toddlers showed more book-related verbalizations (print 15.0; enhanced 11.5 [P < .001]; basic 12.5 [P = .005]), total verbalizations (print 18.8; enhanced 13.8 [P < .001]; basic 15.3 [P < .001]), and higher collaboration scores (print 3.1; enhanced 2.7 [P = .004]; basic 2.8 [P = .02]) with print-book reading.

CONCLUSIONS

Parents and toddlers verbalized less with electronic books, and collaboration was lower. Future studies should examine specific aspects of tablet-book design that support parent-child interaction. Pediatricians may wish to continue promoting shared reading of print books, particularly for toddlers and younger children.

When Representation Becomes Reality: Interactive Digital Media and Symbolic Development

One challenge of using an interesting object such as a scale model as a symbol for something else is children's deep interest in the object itself. Attending to the model (the symbol) as a toy, children do not use information about where in the model a tiny dog is hiding to mentally represent where a larger dog is hiding in the full-sized room (the referent). Young children use pictures in this way because they are relatively uninteresting as objects. Today, interactive images on touchscreens function as virtual objects on which to act and which respond to the user's actions. In this chapter, we examine how interactive symbolic media (e.g., touchscreens, video chat, augmented reality) might affect children's symbolic development and the way that psychologists think about representational objects. Young children's learning about and from interactive media may depend upon adults scaffolding children's use of these new cultural tools.

Let's Chat: On-Screen Social Responsiveness Is Not Sufficient to Support Toddlers' Word Learning From Video

Joint engagement with a speaker is one cue children may use to establish that an interaction is relevant to them and worthy of attention. People on pre-recorded video cannot engage contingently with a viewer in shared experiences, possibly leading to deficits in learning from video relative to learning from responsive face-to-face encounters. One hundred and thirty two toddlers (24 and 30 months old) were offered referential social cues disambiguating a novel word's meaning in one of four conditions: responsive live (a speaker was present and engaged with children); unresponsive video (a speaker on video looked at the camera and smiled at scripted times); unresponsive live (although present, the speaker behaved as she did on the unresponsive video), and responsive video (a speaker on closed-circuit video engaged with children, as in video chat). Children of both ages reliably learned the word in the responsive live condition, and older children (30 months) learned in the unresponsive live condition. Neither group learned in the responsive or unresponsive video conditions. The results show that the addition of communicative social cues to the video presentation via video chat was not sufficient to support learning in this case. Rather, toddlers' transfer and generalization of words presented on video chat may depend on other contextual factors, such as co-viewers who scaffold their learning. Live, responsive video as implemented in this and prior studies is compared, with implications for the use of video chat via the Internet with young children.
