Mechanisms of social evaluation in infancy: A preregistered exploration of infants � eye?movement and pupillary responses to prosocial and antisocial events
AbstractPast research shows infants selectively touch and look longer at characters who help versus hinder others (Social evaluation by preverbal infants.Nature, 2007, 450, 557; Three-month-olds show a negativity bias in their social evaluations.Developmental Science, 2010, 13, 923); however, the mechanisms underlying this tendency remain underspecified. The current preregistered experiment approaches this question by examining infants � real-time looking behaviors during prosocial and antisocial events, and exploring how individual infants� looking behaviors correlate with helper preferences. Using eye-tracking, 34 five-m...

Happy, sad, or yucky? Parental emotion talk with infants in a book ‐sharing task
AbstractWhile preschoolers consistently produce and use labels for happy and sad emotional states, labels for other emotional states (e.g., disgust) emerge much later in development. One explanation for these differences may lie in how parents first talk about these emotions with their children in infancy and toddlerhood. The current study examined parent talk about different emotions (i.e., happiness, sadness, anger, fear, and disgust) in a book-sharing task with their 12- to 24-month-old infants. Parental talk on each emotion page was coded for both quantity and quality of emotion talk. We found that, rather than labelin...

Visual statistical learning in infancy: Discrimination of fine ‐grained regularities depends on early test trials
AbstractInfants ’ ability to detect statistical regularities between visual objects has been demonstrated in previous studies (e.g., Kirkham et al.,Cognition, 83, 2002, B35). The extent to which infants extract and learn the actual values of the transitional probabilities (TPs) between these objects nevertheless remains an open question. In three experiments providing identical learning conditions but contrasting different types of sequences at test, we examined 8-month-old infants ’ ability to discriminate between familiar sequences involving high or low values of TPs, and new sequences that involved null TPs. Results...

Still connecting the dots: An investigation into infants' attentional bias to threat using an eye ‐tracking task
This study was the first to use a consistent measure of negative affect across the whole sample. An eye-tracking dot-probe task was used to examine attentional bias toward threat (i.e., angry faces) relative to positive (i.e., happy faces) stimuli. Results showed that an attention bias to threat was not characteristic of infants at this age, and negative affect did not moderate the putative relationship between attention and emotional faces (angry, happy). These findings therefore suggest that attention biases to socio-emotional threat may no t have emerged by 11 months old. (Source: Infancy)

Does social modeling increase infants ’ willingness to accept unfamiliar foods?
AbstractDespite a rich knowledge base about infants ’ social learning and studies observing social referencing in other species in food contexts, we know surprisingly little about social learning about food among human infants. This gap in the literature is particularly surprising considering that feeding unfamiliar foods to infants is a very commo n experience as infants begin to eat solid foods. The present study examines whether parental social modeling influences infants’ willingness to accept unfamiliar foods. In two Zoom sessions, parents will be asked to feed unfamiliar foods to their 6- to 24-month-old infants ...

Engaging with happy ‐sounding music promotes helping behavior in 18‐month‐olds
AbstractEngaging with music fosters prosocial responding in infants and toddlers. In this pilot study, we examined whether music that expresses contrasting emotions (happy vs. sad) was associated with toddlers ’ helpfulness. Seventy-five 18-month-olds from Hong Kong China were randomly assigned to engage with music with an experimenter in one of two conditions:happy- orsad-sounding music. After the musical engagement task, toddlers from both conditions completed the same set of helping tasks. For instrumental (action-based) helping, toddlers were significantly more helpful after engaging with happy-sounding music than wi...

Using video observation in the family context: The association between camera ‐related behaviors and parental sensitivity
AbstractResearch on parental sensitivity often relies on video observation of parent –infant dyads. However, to date, no study has assessed both infants’ and parents’ interactions with the camera, and how this relates to parental sensitivity levels. This exploratory study micro-coded camera-related behaviors (CRB) by 4-month olds and their mothers and fathers on a 1-s time bas e, and examined the associations between those behaviors and parental sensitivity in 75 Dutch families. While parents’ CRB made up only 0.8% of total interaction time, infants’ made up 12%. Multi-level time-series analyses showed that infan...

Associations between acoustic features of maternal speech and infants ’ emotion regulation following a social stressor
This study examined whether maternal prosody predicted changes in infants ’ biobehavioral state after the still face, a stressor in which the mother withdraws and reinstates social engagement. Ninety-four dyads participated in the study (infant age 4–8 months). Infants’ heart rate and respiratory sinus arrhythmia (measuring cardiac vagal tone) were derived from an electrocardiogram (ECG). Infants’ behavioral distress was measured by negative vocalizations, facial expressions, and gaze aversion. Mothers’ vocalizations were measured via a composite of spectral analysis and spectro-temporal modulation using a two-d...

Exploring developmental changes in infant anticipation and perceptual processing: EEG responses to tactile stimulation
AbstractThere is an increasing interest in alpha-range rhythms in the electroencephalogram (EEG) in relation to perceptual and attentional processes. The infant mu rhythm has been extensively studied in the context of linkages between action observation and action production in infancy, but less is known about the mu rhythm in relation to cross-modal processes involving somatosensation. We investigated differences in mu responses to cued vibrotactile stimulation of the hand in two age groups of infants: From 6 to 7 months and 13 to 14 months. We were also interested in anticipatory neural responses in the alpha frequenc...

A self ‐comfort oriented pattern of regulatory behavior and avoidant attachment are more likely among infants born moderate‐to‐late preterm
AbstractInfants born preterm (<37 gestational weeks, GW) are at increased risk for regulatory difficulties and insecure attachment. However, the association between infants' regulatory behavior patterns and their later attachment organization is understudied in the preterm population. We addressed this gap by utilizing a Portugues e sample of 202 mother–infant dyads. Specifically, we compared the regulatory behavior patterns of 74 infants born moderate-to-late preterm (MLPT, 32–36 GW) to those of 128 infants born full-term (FT, 37–42 GW) and evaluated the associations of these regulatory patterns with later atta...

“Did I just do that?”—Six‐month‐olds learn the contingency between their vocalizations and a visual reward in 5 minutes
AbstractIt has been shown that infants can increase or modify a motorically available behavior such as sucking, kicking, arm waving, etc., in response to a positive visual reinforcement (e.g., DeCasper& Fifer, 1980; Millar, 1990; Rochat& Striano, 1999; Rovee-Collier, 1997; Watson& Ramey, 1972). We tested infants to determine if they would also change their vocal behavior in response to contingent feedback, which lacks the social, emotional, and auditory modeling typical of parent-child interaction. Here, we show that in a single five-minute session infants increase the rate of their vocalizations in order to control the ap...
