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.     

Infant screen exposure links to toddlers' inhibition,but not other EF constructs: A propensity score study

Technology is pervasive in homes of families with young children, despite evidence for negative associations between infant exposure to screen‐based media and cognitive development that has led the American Academy of Pediatrics (AAP) to discourage parents from exposing children under the age of 18 months to any kind of screen time (AAP, 2016). Here, we apply a propensity score matching approach to estimate relations between electronic screen‐based media use in infancy and executive function in early toddlerhood. In an international sample of 416 firstborn infants, parental report of regular exposure to screen‐based media at 4 months predicted poorer performance on a test of inhibition at 14 months, but was unrelated to either cognitive flexibility or working memory at 14 months. Results of this study are therefore consistent with the view that early exposure to screen‐based media adversely affects the development of executive function.     

An Eye Tracking Investigation of Color–Location Binding in Infants' Visual Short‐Term Memory

Two experiments examined 8‐ and 10‐month‐old infants' (N = 71) binding of object identity (color) and location information in visual short‐term memory (VSTM) using a one‐shot change detection task. Building on previous work using the simultaneous streams change detection task, we confirmed that 8‐ and 10‐month‐old infants are sensitive to changes in binding between identity and location in VSTM. Further, we demonstrated that infants recognize specifically what changed in these events. Thus, infants' VSTM for binding is robust and can be observed in different procedures and with different stimuli.     

The Ability to Map Differentially Stressed Labels to Objects Predicts Language Development at 24 months in 12‐month‐olds at High Risk for Autism

Sensitivity to language‐specific stress patterns during infancy facilitates finding, mapping, and recognizing words, and early preferences for the predominate stress pattern of the infant's native language have been argued to facilitate language relevant outcomes (Ference & Curtin, 2013 Journal of Experimental Child Psychology, 116, 891; Weber et al., 2005 Cognitive Brain Research, 25, 180). We examined 12‐month‐old infant siblings of typically developing children (SIBS‐TD) and infant siblings of children diagnosed with autism spectrum disorder (ASD; SIBS‐A) on their ability to map differentially stressed labels to objects. We also examined whether success at this task relates to infants’ vocabulary size at 12 months, and more specifically to SIBS‐A's vocabulary at both 12 and 24 months. SIBS‐TD successfully mapped the word–object pairings, which related to their vocabulary comprehension at 12 months. In contrast, SIBS‐A as a group did not map the word–object pairings, which was unrelated to vocabulary size at 12 months. However, success on this task for SIBS‐A predicted expressive language abilities at 24 months using the Mullen Scales of Early Learning (MSEL; Mullen, 1995 Mullen Scales of Early Learning. Circle Pines, MN: American Guidance) and the MacArthur‐Bates Communicative Development Inventory (MB‐CDI; Fenson et al., 1993 MacArthur Communicative Development Inventory: Users Guide and Technical Manual. San Diego, CA: Singular Publishing Company). Our study is the first to demonstrate that 12‐month‐old SIBS‐A who succeed at word mapping using lexical stress are more likely to have stronger expressive language abilities at 24 months.     

Early Word Segmentation in Naturalistic Environments: Limited Effects of Speech Register

We examined 7.5‐month‐old infants' ability to segment words from infant‐ and adult‐directed speech (IDS and ADS). In particular, we extended the standard design of most segmentation studies by including a phase where infants were repeatedly exposed to target word recordings at their own home (extended exposure) in addition to a laboratory‐based familiarization. This enabled us to examine infants' segmentation of words from speech input in their naturalistic environment, extending current findings to learning outside the laboratory. Results of a modified preferential‐listening task show that infants listened longer to isolated tokens of familiarized words from home relative to novel control words regardless of register. However, infants showed no recognition of words exposed to during purely laboratory‐based familiarization. This indicates that infants succeed in retaining words in long‐term memory following extended exposure and recognizing them later on with considerable flexibility. In addition, infants segmented words from both IDS and ADS, suggesting limited effects of speech register on learning from extended exposure in naturalistic environments. Moreover, there was a significant correlation between segmentation success and infants' attention to ADS, but not to IDS, during the extended exposure phase. This finding speaks to current language acquisition models assuming that infants' individual attention to language stimuli drives successful learning.     

Beneficial effects of the mother's voice on infants’ novel word learning

The maternal voice appears to have a special role in infants’ language processing. The current eye‐tracking study investigated whether 24‐month‐olds (n = 149) learn novel words easier while listening to their mother's voice compared to hearing unfamiliar speakers. Our results show that maternal speech facilitates the formation of new word–object mappings across two different learning settings: a live setting in which infants are taught by their own mother or the experimenter, and a prerecorded setting in which infants hear the voice of either their own or another mother through loudspeakers. Furthermore, this study explored whether infants’ pointing gestures and novel word productions over the course of the word learning task serve as meaningful indexes of word learning behavior. Infants who repeated more target words also showed a larger learning effect in their looking behavior. Thus, maternal speech and infants’ willingness to repeat novel words are positively linked with novel word learning.     

Postural Position Constrains Multimodal Object Exploration in Infants

Recent research has revealed the important role of multimodal object exploration in infants' cognitive and social development. Yet, the real‐time effects of postural position on infants' object exploration have been largely ignored. In the current study, 5‐ to 7‐month‐old infants (N = 29) handled objects while placed in supported sitting, supine, and prone postures, and their spontaneous exploratory behaviors were observed. Infants produced more manual, oral, and visual exploration in sitting compared to lying supine and prone. Moreover, while sitting, infants more often coupled manual exploration with mouthing and visual examination. Infants' opportunities for learning from object exploration are embedded within a real‐time postural context that constrains the quantity and quality of exploratory behavior.     

Toddlers Involve Their Caregiver to Help Another Person in Need

Three experiments with 18‐ to 35‐month‐old children (n = 169) studied toddler–caregiver interactions when being confronted with another person in need. In particular, we explored whether toddlers would request their caregiver to help a needy other when they are not able to help themselves. Children observed another person who needed help to accomplish a task, but were either not able to provide help as the object was out of reach (Experiment 1) or because an obstacle prevented children from interacting with the other person (Experiments 2, 2b). The experiments revealed the same developmental trend with 2.5‐year‐olds selectively involving their caregiver to help the needy other. The results are interpreted in terms of toddlers’ motivation to see others helped and with respect to their developing ability to actively involve others to regulate their emotions.     

The Effect of Social Responsiveness on Infants' Object‐Directed Imitation

Previous research has demonstrated that social interactions underlie the development of object‐directed imitation. For example, infants differentially learn object action sequences from a live social partner compared to a social partner over a video monitor; however, what is not well understood is what aspects of social interactions influence social learning. Previous studies have found variable influences of different types of caregiver responsiveness on attention, language, and cognitive development. Therefore, the purpose of this study was to examine how the responsive style of a social partner influenced the learning of object‐directed action sequences. Infants interacted with either a sensitive or redirective experimenter before the learning trial. Results revealed infants changed their patterns of engagement; infants interacting with a sensitive experimenter had longer periods of attentional engagement than infants interacting with a redirective experimenter. Furthermore, during the learning trial, the amount of sensitivity during interaction with the social partner predicted learning scores. These findings suggest that infants' attention is influenced by social partners' interactive style during ongoing interaction, which subsequently affects how infants learn from these social partners.     

Emotion Regulation in Context: Situational Effects on Infant and Caregiver Behavior

Emotion regulation is an important developmental task of the early years of life. However, situational effects are rarely examined. In this study, we evaluated situational effects on 7‐month‐olds' and their mothers' emotional expression and interactive regulation behavior, individual differences across situations, and intercorrelations within situations. Mother‐infant dyads (N = 225) were observed interacting during episodes from play, teaching, and still‐face situations that varied along 2 developmentally salient dimensions: emotional challenge (low vs. high), and attentional focus (face‐to‐face vs. object). Attentional focus affected mothers' behavior, whereas both challenge and attentional focus affected infants. Associations between mother and infant behaviors varied in each situation. High‐challenge situations provided more consistent individual differences in infants and more negative behavior from mothers. Findings have implications for appropriate assessment of emotion regulation in infancy.     

Is a Bird an Apple? The Effect of Speaker Labeling Accuracy on Infants' Word Learning,Imitation, and Helping Behaviors

This study examined infants' sensitivity to a speaker's verbal accuracy and whether the reliability of the speaker had an effect on their selective trust. Forty‐nine 18‐month‐old infants were exposed to a speaker who either accurately or inaccurately labeled familiar objects. Subsequently, the speaker administered a series of tasks in which infants had an opportunity to: learn a novel word, imitate the speaker's “irrational” actions, and help the speaker obtain an out‐of‐reach object. In contrast to infants in the accurate (reliable) condition, those in the inaccurate (unreliable) condition performed more poorly on a word‐learning task and were less likely to imitate. All infants demonstrated high rates of instrumental helping behavior. These results are the first to demonstrate that infants as young as 18 months of age cannot only detect a speaker's verbal inaccuracy but also use this information to attenuate their word recognition and learning of novel actions.     

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.     

How to Build an Intentional Android: Infants' Imitation of a Robot's Goal‐Directed Actions

This study examined whether young children are able to imitate a robot's goal‐directed actions. Children (24–35 months old) viewed videos showing a robot attempting to manipulate an object (e.g., putting beads inside a cup) but failing to achieve its goal (e.g., beads fell outside the cup). In 1 video, the robot made eye contact with a human before and after it failed the action. In another video, the robot did not make eye contact with the human adult. Only in the former condition did children “imitate” the robot's “intended” but unconsummated actions (e.g., putting beads inside a cup). When the robot did not make eye contact, children performed poorly, at the baseline level. These results suggest that human‐like gaze behaviors, not human‐like morphology, may play an important role in young children's imitation of a nonhuman agent's goal‐directed behaviors.     

Early Adolescents' Development of Academic Self‐Concept and Intrinsic Task Value: The Role of Contextual Feedback

In this study, we investigate the extent to which achievement‐related feedback in two academic domains (mathematics and language) originating from two contexts (school and family) predicts early adolescents' domain‐specific academic self‐concept and intrinsic task values in Germany (N = 1,190, age range 10–13) and the United States (N = 1,953, age range 10–14). We examined the mediating role of both parents' competence perceptions and the early adolescents' academic self‐concepts linking grades and intrinsic value. Within‐ and cross‐domain effects were tested at each stage of the mediation. As predicted, in both countries the associations of grades with the academic self‐concepts are mediated by the parents' competence perceptions. The association of academic feedback with intrinsic task value is mediated through the students' academic self‐concepts.     

Measuring Children's Experience of Their Right to Participate in School and Community: A Rights‐Based Approach

This paper discusses the development of a children's rights‐based measure of participation and the findings from its use in a survey of 10‐ to 11‐year‐old children (n = 3773). The measure, which was developed in collaboration with a group of children, had a high reliability (Cronbach's alpha = 0.89). Findings suggest that children's positive experience of their participation rights is higher in school than in community, and higher for girls compared to boys. It is argued that involving children in the ‘measurement’ of their own lives has the potential to generate more authentic data on children's lived experiences.     

Exploring Parents' Experiences and Reactions to Adolescents' Hyperactivity,Impulsivity, and Attention Problems

Adolescents' hyperactivity, impulsivity, and attention problems (HIA) have been shown to make parents feel powerless. In this study, the authors examined whether these feelings were dependent on parents' experiences with their older children. Two models that offer different predictions of how parents make use of their earlier experiences when raising their later‐born children were explored: the learning‐from‐experience model and the spillover model. The authors used reports from 372 parents with 1 child (M_age = 11.92) and 198 parents with 2 children (M_age = 11.89 and 14.35) from a small town in a European country. The results did not support a learning‐from‐experience process. Instead, consistent with a spillover process, parents felt particularly powerless about their younger children with HIA if they also felt powerless about their older children. This study suggests that parents' experiences of raising their older children are important for their reactions to HIA in their younger children     

Investigating the Relation Between Infants' Manual Activity With Objects and Their Perception of Dynamic Events

We examined the relation between 6‐ and 7‐month‐old infants' (N = 60) manual activity with objects during free play and their perception of the features of dynamic, multimodal events. Infants were habituated to a single event in which a hand reached for and manipulated a colorful, multifeatured object, and a sound was heard (e.g., a hand squeezed a purple round object, causing a whistling sound) and then their response to events that involved a change in the appearance of the object, the action, or the sound was assessed. Infants responded least to changes in the appearance of the objects, and their sensitivity to this feature was related to their manual activity with objects during free play. Infants' responding to changes in the sound or action was unrelated to motor activity, suggesting that at this age motor achievements related to object exploration are associated with infants' perception of some, but not all, object features.     

Children's Interaction With Commercials*

Public policy attention to numerous issues arising from children's television commercials has resulted in considerable research interest in this area. Most studies have been based on 1) cognitive developmental approaches; 2) survey methods based on parental reports of child viewing; 3) a view of the child as an atomized entity in the viewing environment. This study focuses on interactive episodes of child viewing. Behavior specimens of interactive viewing collected by naturalistic methods are presented illustrating children and parents actively shaping the commercial viewing situation.     

Intensive interaction and autism: some theoretical concerns

The authors consider the possible application of intensive interaction to children with autism. Intensive interaction is briefly described, and the question asked whether children with autism (and developmental delay) can gain from this exemplar of naturalistic, interactive approaches to facilitating sociability and communication. A theoretical approach is taken to unravel the difficulties faced by children with autism in developing sociability and communication, and the way in which intensive interaction functions. Five areas of possible mismatch between the particular difficulties/needs of these children and the method are identified and interrogated. The authors conclude that children with autism can be enabled to learn about interaction and communication through this naturalistic and supportive process. The need for empirical evidence to substantiate this position is highlighted. Copyright © 2000 John Wiley & Sons, Ltd.
