RESUMO

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.

RESUMO

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.

RESUMO

American parents describe bonding with their child as a primary reason for engaging in shared picture book reading. One prominent reading intervention (dialogic reading) reliably increases language outcomes, but until recently, has not been evaluated for how well it promotes warm parent-child interactions. In this study, a digital application designed to promote parent-child conversation by modeling dialogic questioning also increased mutuality, positivity, and on-task behaviors. Three- and 4-year-old American children (n = 73) and their parents were randomly assigned to read 10 times at home either: (a) an eBook with a character who modeled dialogic questioning (experimental); (b) a version of the same eBook without modeling (control); or (c) to choose between versions for each reading (choice). An adaption of the PARCHISY coding scheme was used to evaluate parent, child, and dyadic behaviors during in-lab readings at the beginning and end of the 2-week home reading period. At the final visit, experimental group families showed significant growth in mutuality (i.e., responsiveness, reciprocity, and cooperation), on-task behaviors, and parent and child positivity, and displayed more of these behaviors than families not exposed to modeling. Some increases in mutuality and positivity also emerged in families in the choice condition, but fewer than in families who only read the eBook with modeling. Parents and children exhibited no significant changes in negativity in any condition. This study suggests that carefully designed digital technology has the potential to foster positive shared reading interactions between parents and young children.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Young preschoolers rapidly acquire new information from social partners but do not learn efficiently from people on video. We trained parents to use Whitehurst's dialogic reading questioning techniques while watching educational television with their children. Eighty-one parents coviewed storybook videos with their 3-year-old children in 1 of 4 conditions: dialogic questioning (pause, ask questions, and encourage children to tell parts of the story), directed attention (pause and comment but do not ask questions), dialogic actress (show the videos with dialogic questioning by an on-screen actress embedded in them), or no intervention (show the videos as usual). After 4 weeks, children in the dialogic questioning group scored higher than children in the directed attention and no-intervention groups on story comprehension and story vocabulary measures. Scores from the dialogic actress group fell in between. On a standardized measure of expressive vocabulary, children in the 2 parent-interaction groups exhibited significant improvement over their pretest scores. Results indicate that parent-led questioning enhances children's learning from video stories at age 3 and that a video incorporating an on-screen dialogic questioner may also be effective. Mechanisms behind the effect of dialogic reading-style interventions are discussed.

RESUMO

In previous studies, very young children have learned words while "overhearing" a conversation, yet they have had trouble learning words from a person on video. In Study 1, 64 toddlers (mean age=29.8 months) viewed an object-labeling demonstration in 1 of 4 conditions. In 2, the speaker (present or on video) directly addressed the child, and in 2, the speaker addressed another adult who was present or was with her on video. Study 2 involved 2 follow-up conditions with 32 toddlers (mean age=30.4 months). Across the 2 studies, the results indicated that toddlers learned words best when participating in or observing a reciprocal social interaction with a speaker who was present or on video.

RESUMO

In recent years, parents in the United States and worldwide have purchased enormous numbers of videos and DVDs designed and marketed for infants, many assuming that their children would benefit from watching them. We examined how many new words 12- to 18-month-old children learned from viewing a popular DVD several times a week for 4 weeks at home. The most important result was that children who viewed the DVD did not learn any more words from their monthlong exposure to it than did a control group. The highest level of learning occurred in a no-video condition in which parents tried to teach their children the same target words during everyday activities. Another important result was that parents who liked the DVD tended to overestimate how much their children had learned from it. We conclude that infants learn relatively little from infant media and that their parents sometimes overestimate what they do learn.

RESUMO

Imitation of people on educational television is a potential way for very young children to learn new skills. Although toddlers in previous studies exhibited a "video deficit" in learning, 24-month-olds in Study 1 successfully reproduced behaviors modeled by a person who was on video as well as they did those modeled by a person who was present in the room (even after a 24-h delay). Neither displaced filming context nor cuts between actions affected toddlers' imitation from video. Shortening the demonstration in Study 2 affected imitation in the video condition but not in the live condition. In Study 3, 24-month-olds who viewed the original longer videos on their family TV screens (with which they had a viewing history) imitated significantly less than those who viewed the videos on the laboratory monitor. Imitation of a live modeler was the same across settings (home or lab). Implications for toddlers' judgments of reliable information sources and for the design of educational television programs are discussed.

RESUMO

Some individuals with Prader-Willi syndrome exhibit strengths in solving jigsaw puzzles. We compared visuospatial ability and jigsaw puzzle performance and strategies of 26 persons with Prader-Willi syndrome and 26 MA-matched typically developing controls. Individuals with Prader-Willi syndrome relied on piece shape. Those in the control group used a different, picture-focused strategy. Individuals with Prader-Willi syndrome performed better than did the control group on an achromatic interlocking puzzle, whereas scores on puzzles with pictures (interlocking or noninterlocking) did not differ. Visuospatial scores related to performance on all puzzles in the control group and on the noninterlocking puzzle in the Prader-Willi syndrome group. The most proficient jigsaw puzzlers with Prader-Willi syndrome tended to be older and have shape-based strategies.

RESUMO

Using a symbolic object such as a model as a source of information about something else requires some appreciation of the relation between the symbol and what it represents. Representational insight has been proposed as essential to success in a symbolic retrieval task in which children must use information from a hiding event in a scale model to find a toy hidden in a room. The two studies reported here examine and reject a proposed alternative account for success in the model task. The results with 2.5-year-olds and 3-year-olds show that children's successful use of a scale model cannot be attributed to the simple detection of the correspondences between the objects in the two spaces. A higher-level representation of the model-room relation (i.e. representational insight) is required. The results are discussed with respect to the coalescence of multiple factors in determining performance in the model task.

RESUMO

Although prior research clearly shows that toddlers have difficulty learning from video, the basis for their difficulty is unknown. In the 2 current experiments, the effect of social feedback on 2-year-olds' use of information from video was assessed. Children who were told "face to face" where to find a hidden toy typically found it, but children who were given the same information by a person on video did not. Children who engaged in a 5-min contingent interaction with a person (including social cues and personal references) through closed-circuit video before the hiding task used information provided to find the toy. These findings have important implications for educational television and use of video stimuli in laboratory-based research with young children.

RESUMO

Learning to use symbols is a challenge for young children even when the symbol in question (e.g., a live video image) is iconic and seems transparent to adults. This research examined the effect of experience on children's use of video-presented information. Two-year-old children saw themselves "live" on their family television for 2 weeks and then participated in an object-retrieval task. The children reliably used a live video presentation of an adult hiding a toy in an adjoining room to find the toy. Most also transferred what they learned to a task involving another symbol (pictures) that typically is very difficult for this age group. The results reveal flexibility in 2-year-olds' symbol use that follows from successful representation of a symbolic relation.
