Infant Gaze Following During Parent-Infant Coviewing of Baby Videos

Sleep-dependent memory consolidation of televised content in infants

Infants face the constant challenge of selecting information for encoding and storage from a continuous incoming stream of data. Sleep might help in this process by selectively consolidating new memory traces that are likely to be of future relevance. Using a deferred imitation paradigm and an experimental design, we asked whether 15- and 24-month-old infants (N = 105) who slept soon after encoding a televised demonstration of target actions would show higher imitation scores (retention) after a 24-h delay than same-aged infants who stayed awake for ≥4 h after encoding. In light of infants' well-known difficulties in learning and remembering information from screens, we tested if increasing the relevance of the televised content via standardised caregiver verbalisations might yield the highest imitation scores in the sleep condition. Regardless of sleep condition, 24-month-olds exhibited retention of target actions while 15-month-olds consistently failed to do so. For 24-month-olds, temporal recall was facilitated by sleep, but not by parental verbalisations. Correlational analyses revealed that more time asleep within 4 h after encoding was associated with better retention of the target actions and their temporal order in 24-months-olds. These results suggest that sleep facilitates memory consolidation of screen-based content in late infancy and that this effect might not hinge on caregivers' verbal engagement during viewing.

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.

Variability in infant social responsiveness: Age and situational differences in attention-following

Attention following (AF) is a cornerstone of social cognitive development and a longstanding topic of infancy research. However, there is conflicting evidence regarding the development of AF. One reason for discrepant findings could be that infants' AF responses do not generalize across settings, and are influenced by situational factors. Theories of AF development based on data collected in laboratory paradigms might skew our understanding of infants' everyday AF. To reveal more generalizable patterns of infant AF development, we compared healthy, North American infants' (N = 48) AF developmental trajectories between a controlled laboratory paradigm and a naturalistic, home-based, parent-directed paradigm. Longitudinal micro-behavioral coding was analyzed to compare individual infants' AF between the two settings every month from 6 to 9 months of age. We aimed to (1) examine longitudinal development of infant AF in two settings; (2) compare AF development between settings, and (3) explore differences in adult cueing behaviors that influence AF. We found that longitudinal trajectories of AF differed between home and lab, with more AF at home in earlier months. Additionally, AF at home was related to maternal cueing variables including bid duration and frequency. These results have implications for the assessment of infants' developing social attention behaviors.

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.

Infant media use: A harm reduction approach

There are a myriad of potentially harmful developmental outcomes associated with infant digital media use. Studies revealing risk associated with early media use have informed the current American Academy of Pediatrics (AAP) recommendations that discourage most digital media use among children under 18 months of age. Recent research advances, however, suggest potential benefits of technology engagement in this age group. Additionally, surveys of parents reveal that most infants engage with digital media for at least 30 min a day, exceeding the AAP recommendations. In response to these discoveries and cultural trends, some scholars have made compelling cases to adapt the AAP guidelines for infants. A helpful model for developing infant digital media use guidelines for families may be the harm reduction approach. The intent of this review is to suggest adaptations to the AAP guidelines for infant media engagement using a harm reduction framework. This review describes the challenge of restrictive guidelines, briefly summarizes the harm reduction approach, provides a review of risks and benefits associated with infant media use in each developmental domain (physical, cognitive, and socioemotional), summarizes correlates of infant screen media use, and examines intervention strategies for reducing screen time. The paper concludes with examples of possible adaptations to current AAP infant media use recommendations using harm reduction and bioecological frameworks.

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.

Infant screen media usage and social-emotional functioning

There has been little research on whether and how screen media usage affects social-emotional (SE) function prior to two years of age, even though early SE development is understood to be nurtured through interpersonal experience, mainly withthe primary caregiver. This study sought to characterise infant screen media usage and understand how it may link with concurrent SE function by testing associated effects on reducing parent-infant interaction and of parent psychological factors. Questionnaire responses from 327 UK-based parents of infants aged 6-24 months showed diverse usage in the amount of time spent on screen media ('screen time') and amount of parental involvement (co-sharing and co-referencing). Infants with possible SE delay experienced more screen time than those at low risk. The study tested three mediation models and found support for the displacement and not distancing hypothesis based on this community sample. While screen time predicted both SE competence and SE problems, reduced parent-infant play partially mediated the effect on SE competence. Parent depressed mood was positively linked with infant SE problems, but there was little evidence that increased screen time mediated this effect. Also, parent reflective function and attitudes toward parent-infant play were unrelated to screen time. Though longitudinal study is warranted, the findings implicate screen media usage as potentially directly and indirectly relevant when addressing infant mental health.

Children aged 6-24 months like to watch YouTube videos but could not learn anything from them

AIM

Parents sometimes show young children YouTube videos on their smartphones. We studied the interaction of 55 Indian children born between December 2014 and May 2015 who watched YouTube videos when they were 6-24 months old.

METHODS

The children were recruited by the researchers using professional and personal contacts and visited by the same two observers at four ages, for at least 10 minutes. The observers recorded the children's abilities to interact with touch screens and identify people in videos and noted what videos attracted them the most.

RESULTS

The children were attracted to music at six months of age and were interested in watching the videos at 12 months. They could identify their parents in videos at 12 months and themselves by 24 months. They started touching the screen at 18 months and could press the buttons that appeared on the screen, but did not understand their use. The children preferred watching dance performances by multiple artists with melodical music, advertisements for products they used and videos showing toys and balloons.

CONCLUSION

Children up to two years of age could be entertained and kept busy by showing them YouTube clips on smartphones, but did not learn anything from the videos.

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

Social cues are one way young children determine that a situation is pedagogical in nature-containing information to be learned and generalized. However, some social cues (e.g., contingent gaze and responsiveness) are missing from prerecorded video, a potential reason why toddlers' language learning from video can be inefficient compared with their learning directly from a person. This study explored two methods for supporting children's word learning from video by adding social-communicative cues. A sample of 88 30-month-olds began their participation with a video training phase. In one manipulation, an on-screen actress responded contingently to children through a live video feed (similar to Skype or FaceTime "video chat") or appeared in a prerecorded demonstration. In the other manipulation, parents either modeled responsiveness to the actress's on-screen bids for participation or sat out of their children's view. Children then viewed a labeling demonstration on video, and their knowledge of the label was tested with three-dimensional objects. Results indicated that both on-screen contingency and parent modeling increased children's engagement with the actress during training. However, only parent modeling increased children's subsequent word learning, perhaps by revealing the symbolic (representational) intentions underlying this video. This study highlights the importance of adult co-viewing in helping toddlers to interpret communicative cues from video.

The Role of the Human Mirror Neuron System in Supporting Communication in a Digital World

Humans use both verbal and non-verbal communication to interact with others and their environment and increasingly these interactions are occurring in a digital medium. Whether live or digital, learning to communicate requires overcoming the correspondence problem: There is no direct mapping, or correspondence between perceived and self-produced signals. Reconciliation of the differences between perceived and produced actions, including linguistic actions, is difficult and requires integration across multiple modalities and neuro-cognitive networks. Recent work on the neural substrates of social learning suggests that there may be a common mechanism underlying the perception-production cycle for verbal and non-verbal communication. The purpose of this paper is to review evidence supporting the link between verbal and non-verbal communications, and to extend the hMNS literature by proposing that recent advances in communication technology, which at times have had deleterious effects on behavioral and perceptual performance, may disrupt the success of the hMNS in supporting social interactions because these technologies are virtual and spatiotemporal distributed nature.

Putting Education in “Educational” Apps

Children are in the midst of a vast, unplanned experiment, surrounded by digital technologies that were not available but 5 years ago. At the apex of this boom is the introduction of applications (“apps”) for tablets and smartphones. However, there is simply not the time, money, or resources available to evaluate each app as it enters the market. Thus, “educational” apps—the number of which, as of January 2015, stood at 80,000 in Apple’s App Store (Apple, 2015)—are largely unregulated and untested. This article offers a way to define the potential educational impact of current and future apps. We build upon decades of work on the Science of Learning, which has examined how children learn best. From this work, we abstract a set of principles for two ultimate goals. First, we aim to guide researchers, educators, and designers in evidence-based app development. Second, by creating an evidence-based guide, we hope to set a new standard for evaluating and selecting the most effective existing children’s apps. In short, we will show how the design and use of educational apps aligns with known processes of children’s learning and development and offer a framework that can be used by parents and designers alike. Apps designed to promote active, engaged, meaningful, and socially interactive learning—four “pillars” of learning—within the context of a supported learning goal are considered educational.

The role of interest in the transmission of social values

The environment is so rich with information that our cognitive system would be overloaded without a way to evaluate what is relevant for our needs and goals. Appraisal theory has shown how emotions, by "tagging" the environment with differential values, enable the attribution of our attentional resources to what is most relevant in any given circumstances. Most often, however, the different cues triggering the allocation of attention are thought of as purely individualistic, like physiological needs or past encounters with certain stimuli. This approach is perfectly appropriate for objects, organisms or events that, by their intrinsic properties, affect the organism's well being. But for humans, many aspects of the environment are culturally or temporally dependent: a soccer game may be highly relevant to some, but not at all to others. This paper contributes to a better understanding of the processes by which different elements of our social environment acquire value through our socialization process. We recruit different concepts proposed by developmental psychologists to shed some light on this social acquisition of relevance. The notion of "joint attention," for example, is particularly important to understand how we are sensitive to the other's focus of attention. Similarly, the term "social referencing" has been used to describe the process of taking into account the affective reaction to a given stimuli, in order to direct our behavior. At the core of this process, called "social appraisal" by Manstead, we propose that a specific emotion plays a major role: interest. Someone else's expression of interest, which seems to be detectable from a very early age, is extremely useful in gauging what is worthy of attention among stimuli that are not inherently interesting. The paper highlights how external sources of information (the life experiences of community members) indicate what is relevant, thus giving access to the social values of that group.
