Talker variability shapes early word representations in English ?learning 8?month?olds
AbstractInfants must form appropriately specific representations of how words sound and what they mean. Previous research suggests that while 8-month-olds are learning words, they struggle with recognizing different-sounding instances of words (e.g., from new talkers) and with rejecting incorrect pronunciations. We asked how adding talker variability during learning may change infants ability to learn and recognize words. Monolingual English-learning 7- to 9-month-olds heard a single novel word paired with an object in either a no variability, within-talker variability, or between-talker variability habituation. We...

Joint engagement in the home environment is frequent, multimodal, timely, and structured
AbstractInfants develop in a social context, surrounded by knowledgeable caregivers who scaffold learning through shared engagement with objects. However, researchers have typically examined joint engagement in structured tasks, where caregivers sit near infants and display frequent, prompt, and multimodal behaviors around the objects of infant action. Which features of joint engagement generalize to the real-world? Despite the importance of joint engagement for infant learning, critical assumptions around joint engagement in everyday interaction remain unexamined. We investigated behavioral and temporal features of joint ...

Spontaneous movements, motor milestones, and temperament of preterm âborn infants: Associations with motherâinfant attunement
AbstractPreterm-born infants and their mothers are at higher risk of showing less attuned interactions. We sought to identify characteristics of preterm-born infants associated with the attunement of mother âinfant interactions at the corrected ages of 3â4 months, looking specifically at motor behaviors. We focused on infantsâ spontaneous movements, achievement of motor milestones, and temperament, which at this young age is often manifested via movement. Sixty preterm-born infants (Mdngestation age in weeks = 33, 57.38% male, corrected ageMdn = 14 weeks, interquartile range = 13â16) and their mothers parti...

The development of visual attention in early infancy: Insights from a free âviewing paradigm
AbstractTheories of visual attention suggest a cascading development of subfunctions such as alertness, spatial orientation, attention to object features, and endogenous control. Here, we aimed to track infants â visual developmental steps from a primarily exogenously to more endogenously controlled processing style during their first months of life. In this repeated measures study, 51 infants participated in seven fortnightly assessments at postterm ages of 4â16Â weeks. Infants were presented with the same set of static and dynamic paired comparison stimuli in each assessment. Visual behavior was evaluated by a newly ...

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 with...

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 infants CRB pr...

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 48 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-dimensional ...

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 motherinfant dyads. Specifically, we compared the regulatory behavior patterns of 74 infants born moderate-to-late preterm (MLPT, 3236 GW) to those of 128 infants born full-term (FT, 3742 GW) and evaluated the associations of these regulatory patterns with later attachment....

A Bayesian meta ?analysis of infants ability to perceive audiovisual congruence for speech
AbstractThis paper quantifies the extent to which infants can perceive audio visual congruence for speech information and assesses whether this ability changes with native language exposure over time. A hierarchical Bayesian robust regression model of 92 separate effect sizes extracted from 24 studies indicates a moderate effect size in a positive direction (0.35, CI [0 .21: 0.50]). This result suggests that infants possess a robust ability to detect audiovisual congruence for speech. Moderator analyses, moreover, suggest that infants audiovisual matching ability for speech emerges at an early point in the process of l...

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 (dif...

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)
