Video Deficit in Toddlers’ Object Retrieval: What Eye Movements Reveal About Online Cognition

The purpose of this study was to determine whether toddlers exhibit different eye‐movement patterns when watching real events versus video demonstrations in an object‐retrieval task. Twenty‐four‐month‐olds (N = 36) searched for a sticker on a felt board after watching an experimenter hide it behind a felt object in person or via video. Eye movements during the hiding event were recorded. Compared to those watching in‐person events, children watching video spent more time looking at the target location overall, yet they had relatively poor search performance. Visual attention to the target location predicted search performance in the video condition only; children who watched in‐person hiding events had high success rates even if they paid relatively little visual attention to the correct location. Findings are consistent with the hypothesis that toddlers process information more quickly for in‐person (versus video) events, enabling them to learn as well (or better) despite relatively low selective attention. Thus, relatively poor encoding, as well as memory retrieval, may underlie the video deficit.     

Toddlers Help Anonymously

Young children are extremely motivated to help others, but it is not clear whether they do so in anonymous situations without social recognition. In two studies, we found that 18‐month‐old toddlers provided help equally in situations where an adult recipient was present and in situations where an adult recipient was not present. We included several control conditions to rule out that toddlers were simply unaware of their anonymity or were merely motivated to restore the physical order of things. Together, these findings suggest that early in ontogeny children are motivated to help others in need regardless of whether they can immediately be recognized for their prosocial intentions.     

“Help Yourself!” What Can Toddlers' Helping Failures Tell Us About the Development of Prosocial Behavior?

Prosocial behavior emerges in the second year of life, yet it is typical for children in this period not to share, comfort, or help. We compared toddlers (18, 30 months) who helped with those who did not help on two tasks (instrumental helping; empathic helping). More than half of children failed to help on one or both tasks. Nonhelpers engaged in more hypothesis testing on the instrumental helping task, but more security‐seeking, wariness, and playing on the empathic helping task. Across tasks, children who tended to engage in nonhelping behaviors associated with negative emotional arousal also tended to seek comfort from a parent. In contrast, children who tended to play instead of helping were less likely to exhibit negative emotional arousal or hypothesis testing, suggesting a focus on their own interests. Parents of 18‐month‐old nonhelpers on the instrumental task were less engaged in socializing prosocial behavior in their toddlers than were the parents of helpers. On the empathic helping task, 18‐month‐old nonhelpers had less mature self‐other understanding than did helpers. By examining how the predominant reasons for failing to help vary with age and task, we gain a fuller perspective on the factors involved in the early development of prosocial behavior.     

Attention to Threat as a Predictor of Shyness in the Context of Internalizing and Externalizing Behavior

The duration of children's attention to putative threat has been documented as a consistent predictor of later anxiety in inhibited children across childhood (Fox, New Directions for Child and Adolescent Development, 127, 2010, 33; Pérez‐Edgar & Fox, Child and Adolescent Psychiatric Clinics of North America, 14, 2005, 681). However, attention to threat has not been broadly examined within existing behavioral contexts and has seldom been studied in very early childhood. Whereas toddlers with high levels of internalizing behavior may view fear‐inducing stimuli as a threat, toddlers with high levels of externalizing behavior may demonstrate attention out of interest or sensation seeking. Thus, attention to threat was expected to predict increased toddler shyness in the context of either high internalizing problems or low externalizing behavior. We examined 117 twenty‐four‐month‐old toddlers to determine whether attention to threat interacted with internalizing and externalizing behavior at 24 months of age to predict toddler shyness one year later. Results indicated that attention to threat predicted toddlers' lower shyness at 36 months when toddlers’ externalizing behavior at age 24 months were high, but there was no significant interaction between toddlers’ internalizing behavior and their attention to threat in predicting later shyness. These results expand our understanding of the contexts in which attention to threat in early childhood is a viable predictor of later shyness.     

“It's Just a Lot of Work”: Adolescents’ Self‐Presentation Norms and Practices on Facebook and Instagram

We explored adolescents’ (12‐ to 18‐year‐olds; n = 51) awareness of their audience and subsequent self‐presentation practices on Facebook and Instagram through focus group discussions. Findings suggest that teens, who are developmentally able to perceive a situation from the third‐person perspective and who value peer approval, purposefully share content to appear interesting, well liked, and attractive. Some teens invested great effort into posting by these norms, even asking their friends to help; however, this was more common among girls. Older teens especially discussed taking the perspective of their audience when deciding what to post, which is consistent with the finding that perspective taking continues to develop throughout adolescence. These findings suggest that perspective taking skills and need for peer approval influence self‐presentation online.     

Helping and Cooperation at 14 Months of Age

Two experiments investigated the proclivity of 14‐month‐old infants (a) to altruistically help others toward individual goals, and (b) to cooperate toward a shared goal. The infants helped another person by handing over objects the other person was unsuccessfully reaching for, but did not help reliably in situations involving more complex goals. When a programmed adult partner interrupted a joint cooperative activity at specific moments, infants sometimes tried to reengage the adult, perhaps indicating that they understood the interdependency of actions toward a shared goal. However, as compared to 18‐ and 24‐month‐olds, their skills in behaviorally coordinating their actions with a social partner remained rudimentary. Results are integrated into a model of cooperative activities as they develop over the 2nd year of life.     

Integration of Thought and Action: Arm Weights Facilitate Search Accuracy in 24‐Month‐Old Children

Search errors are common in cognitive tasks with infants and toddlers, and these errors reveal important insights to the development of competence and performance. Rivière and Lécuyer (2008, Journal of Experimental Child Psychology, 100, 1) demonstrated that 29‐month‐olds typically make an error during a search task involving invisible displacement. However, performance improves significantly when children wear weighted wrist bands while doing the task. To investigate this phenomenon further, we tested 24‐month‐old children in an identical search task (N = 35). Half the children wore weighted wrist bands, and the rest were in a no‐weight condition. To test how far this phenomenon generalizes, we also tested the same children in a second search task where they needed to find a ball that had rolled behind one of four doors. The results showed that children in the no‐weight condition replicated previous findings of poor performance on both search tasks. Unlike 29‐month‐olds, the 24‐month‐olds in the weighted condition did not immediately show improvement on the search tasks. However, after an initial search attempt, children wearing weights performed significantly better than chance. The findings shed new light on the interplay between thought and action.     

Sequences of toddler negative emotion and parent–toddler verbal communication during a waking day

Although the second year of life is characterized by dramatic changes in expressive language and by increases in negative emotion expression, verbal communication and emotional communication are often studied separately. With a sample of twenty‐five one‐year‐olds (12–23 months), we used Language Environment Analysis (LENA; Xu, Yapanel, & Gray, 2009, Reliability of the LENA? language environment analysis system in young children’s natural home environment. LENA Foundation) to audio‐record and quantify parent–toddler communication, including toddlers’ vocal negative emotion expressions, across a full waking day. Using a multilevel extension of lag‐sequential analysis, we investigated whether parents are differentially responsive to toddlers’ negative emotion expressions compared to their verbal or preverbal vocalizations, and we examined the effects of parents’ verbal responses on toddlers’ subsequent communicative behavior. Toddlers’ negative emotions were less likely than their vocalizations to be followed by parent speech. However, when negative emotions were followed by parent speech, toddlers were most likely to vocalize next. Post hoc analyses suggest that older toddlers and toddlers with higher language abilities were more likely to shift from negative emotion to verbal or preverbal vocalization following parent response. Implications of the results for understanding the parent–toddler communication processes that support both emotional development and verbal development are discussed.     

Parental Linguistic Input and Its Relation to Toddlers’ Visual Attention in Joint Object Play: A Comparison Between Children with Normal Hearing and Children With Hearing Loss

Parent–child interactions are multimodal, often involving coordinated exchanges of visual and auditory information between the two partners. The current work focuses on the effect of children's hearing loss on parent–child interactions when parents and their toddlers jointly played with a set of toy objects. We compared the linguistic input received by toddlers with hearing loss (HL) and their chronological age‐matched (CA) and hearing age‐matched (HA) normal‐hearing peers. Moreover, we used head‐mounted eye trackers to examine how different parental linguistic input affected children's visual attention on objects when parents either led or followed children's attention during joint object play. Overall, parents of children with HL provided comparable amount of linguistic input as parents of the two normal‐hearing groups. However, the types of linguistic input produced by parents of children with HL were similar to the CA group in some ways and similar to the HA group in other ways. Interestingly, the effects of different types of linguistic input on extending the attention of children with HL qualitatively resembled the patterns seen in the CA group, even though the effects were less pronounced in the HL group. We discuss the implications of these results for our understanding of the reciprocal, dynamic, and multi‐factored nature of parent–child interactions.     

Pregnancy Acceptance,Parenting Stress,and Toddler Attachment in Low‐Income Black Families

Questionnaire items tapping feelings about pregnancy were administered to 173 young, low‐income primiparous Black mothers who either were pregnant or had delivered within the past year. A factor analysis indicated that 11 items together measured mothers’ acceptance of the pregnancies that resulted in the births of their first children. Links to mothers’ later parenting stress, warmth, and their toddlers’ attachment security were explored. Pregnancy acceptance was a negative predictor of one aspect of maternal parenting stress (distress resulting from feelings that parenting is burdensome) and a positive predictor of toddler attachment security. It did not, however, predict another aspect of parenting stress (feelings that interactions with children are not enjoyable) or maternal warmth.     

Resolving the (Apparent) Talker Recognition Paradox in Developmental Speech Perception

The infant literature suggests that humans enter the world with impressive built‐in talker processing abilities. For example, newborns prefer the sound of their mother's voice over the sound of another woman's voice, and well before their first birthday, infants tune in to language‐specific speech cues for distinguishing between unfamiliar talkers. The early childhood literature, however, suggests that preschoolers are unable to learn to identify the voices of two unfamiliar talkers unless these voices are highly distinct from one another, and that adult‐level talker recognition does not emerge until children near adolescence. How can we reconcile these apparently paradoxical messages conveyed by the infant and early childhood literatures? Here, we address this question by testing 16.5‐month‐old infants (N = 80) in three talker recognition experiments. Our results demonstrate that infants at this age have difficulty recognizing unfamiliar talkers, suggesting that talker recognition (associating voices with people) is mastered later in life than talker discrimination (telling voices apart). We conclude that methodological differences across the infant and early childhood literatures—rather than a true developmental discontinuity—account for the performance differences in talker processing between these two age groups. Related findings in other areas of developmental psychology are discussed.     

Early Word Recognition in Sentence Context: French and English 24‐Month‐Olds' Sensitivity to Sentence‐Medial Mispronunciations and Assimilations

Recent work has shown that young children can use fine phonetic detail during the recognition of isolated and sentence‐final words from early in lexical development. The present study investigates 24‐month‐olds' word recognition in sentence‐medial position in two experiments using an Intermodal Preferential Looking paradigm. In Experiment 1, French toddlers detect word‐final voicing mispronunciations (e.g., bu z [by z ] for bu s [by s ] “bus”), and they compensate for native voicing assimilations (e.g., bu z d evant toi [bu zd ?vɑ?twa] “bus in front of you”) in the middle of sentences. Similarly, English toddlers detect word‐final voicing mispronunciations (e.g., shee b for shee p ) in Experiment 2, but they do not compensate for illicit voicing assimilations (e.g., shee b th ere). Thus, French and English 24‐month‐olds can take into account fine phonetic detail even if words are presented in the middle of sentences, and French toddlers show language‐specific compensation abilities for pronunciation variation caused by native voicing assimilation.     

Capturing temporal dynamics of fear behaviors on a moment‐to‐moment basis

Identifying patterns of fearful behaviors early and accurately is essential to identify children who may be at increased risk for psychopathology. Previous work focused on the total amount of fear by using composites across time. However, considering the temporal dynamics of fear expression might offer novel insights into the identification of children at risk. One hundred and twenty‐five toddlers participated in high‐ and low‐fear tasks. Data were modeled using a novel two‐step approach. First, a hidden Markov model estimated latent fear states and transitions across states over time. Results revealed children's behavior was best represented by six behavioral states. Next, these states were analyzed using sequence clustering to identify groups of children with similar dynamic trajectories through the states. A four‐cluster solution found groups of children varied in fear response and regulation process: “external regulators” (using the caregiver as a regulation tool), “low reactive” (low reaction to stimulus), “fearful explorers” (managing their own internal state with minimal assistance from the caregiver), and “high fear” (fearful/at‐caregiver state regardless of task). The combination of analytic tools enabled fine‐grained examination of the processes of fearful temperament. These insights may help prevention programs target behaviors that perpetuate anxious behavior in the moment.     

Reports of Wins and Risk Taking: An Investigation of the Mediating Effect of the Illusion of Control

Two experiments examined the relationships between the knowledge that another person has won in a gamble, the illusion of control and risk taking. Participants played a computer-simulated French roulette game individually. Before playing, some participants learnt that another person won a large amount of money. Results from a first experiment (n = 24) validated a causal model where the knowledge of another person’s win increased the illusion of control, measured with betting times, expectancy and self-reports on scales, which in turn encourages risk taking. In the second experiment (n = 36), some participants were told the previous player acknowledged the win to be fortuitous. The suppression of the belief that the previous winner had himself exerted control over the outcome resulted in lower rates of risk-taking behaviors. This suggests that it was not the knowledge of another person’s win in itself that increased risk taking, but rather, the belief that the other person had some control over the gamble’s outcome. Theoretical implications for the study of social mechanisms involved in gambling behavior are discussed.     

Toddlers’ Responses to Infants’ Negative Emotions

Early developments in toddlers’ responses to adults’ distress have been extensively examined, but less work has been directed to young children's responses to other children in distress. In the current study, we examined 12‐, 18‐, and 24‐month‐old children's (N = 71) behavioral and affective responses to a crying infant (doll) present in the room with the child. A comparison condition included a contented, neutral infant to contrast with the crying infant so as to disambiguate social interest from distress‐specific responding. Results showed that 12‐month‐olds were neither particularly interested in nor concerned about the infant, although they did discriminate between conditions. In contrast, 18‐ and 24‐month‐olds were socially interested and attentive to the infant, but 24‐month‐olds exhibited greater affective concern to the crying infant than did 18‐month‐olds. Children at all three ages were also mildly distressed themselves by the infant's crying, and this did not decline over the second year. Both girls and children without siblings were more interested in the infant; no effects were found for gender, daycare experience, or siblings on affective concern.     

Predicting Permanency Intentions Among Kinship Caregivers

This study examines kinship caregivers’ (n = 830) experiences and their perceptions of the children (n = 1,339) in their care in order to predict permanency intent. Permanency intent is a caregiver’s expressed intent to adopt the child in his or her care or to provide permanent, legal guardianship. The results of this study reveal that most caregivers’ permanency choice is guardianship and not adoption. However, binary logistic regression results uncovered six factors (i.e., thorough explanation of case plans, decreases in caregiver emotional stress, decreases in child depression, child lack of communication with birth parent, caregiver providing care for a sibling group, decreases in run-away behavior) that predict that a caregiver will adopt the child in his or her care. Policy, practice, and research implications are noted.     

Associations Between Toddlers' Naturalistic Media Experience and Observed Learning from Screens

Using secondary analysis, researchers examined associations between two‐year‐olds' (N = 135) naturalistic use of interactive and noninteractive media with performance on a screen‐based learning task. Parents reported the number of minutes that children spent the previous day doing nine media‐related activities (e.g., watching television, playing handheld videogames). The object‐retrieval task required children to watch a hiding event on video and then search for the object on another screen or a real felt board. Results indicated that toddlers' naturalistic experience with interactive (but not noninteractive) media predicted their screen‐based learning in the laboratory. This was true regardless of whether children were tested using interactive or noninteractive video, suggesting that using interactive media (but not watching noninteractive video) is associated with children's learning from screen media generally.     

Infants’ Use of Force to Defend Toys: The Origins of Instrumental Aggression

The two aims of the study were (a) to determine when infants begin to use force intentionally to defend objects to which they might have a claim and (b) to examine the relationship between toddlers’ instrumental use of force and their tendencies to make possession claims. Infants’ and toddlers’ reactions to peers’ attempts to take their toys were assessed in three independent data sets in which the same observational coding system had been used (N = 200). To ensure that infants’ use of force was goal‐directed and not a simple physical reaction, we recorded infants’ reactions when peers picked up toys that the focal infants had just put down, or were nearby or in the focal infants’ mothers’ laps. The use of force in response to peers’ taking over toys was evident before the first birthday, but more common thereafter, although only a minority of children in each sample used force. Analysis of a combined data set revealed that force was deployed more often by 2‐year‐olds than younger infants, and was significantly associated with verbal references to people’s possession of objects. These observations show that toddlers do deploy force intentionally to defend their possessions.     

The Development of Object Construction From Infancy Through Toddlerhood

Early in development, children explore and combine objects in increasingly complex ways. One manual skill, object construction, represents a major shift in how objects are explored relative to other objects. Despite recent connections with cognitive functioning such as spatial skills, the development of object construction ability has rarely been studied and its trajectory has not been adequately described. The purpose of this study was to describe the development of three types of object construction (stacking, nesting, and affixing) across 5 monthly infant visits and 7 monthly toddler visits using a longitudinal design and a large sample size. Infants (10–14 months, n = 131) and toddlers drawn from the infant sample (18–24 months, n = 65) were given sets of age‐appropriate toys each of which elicited at least one type of constructive play. We described success at different construction tasks and identified trends for construction skill for infant and toddler development using multilevel modeling. We found that each of the three construction actions developed in unique ways across the 10‐ to 24‐month period. Infant construction skill predicted the development of toddler skill, but toddler construction skill diverged from infant trajectories. We discuss the role of combination strategies in the development of object construction skill and how object construction could be related to other domains of development.
