Maternal sensitivity during an observed mother-child clean-up task at 18 months and maternal sensitivity during an observed mother-child free-play task at 18 months were tested as independent predictors of child internalizing symptoms, externalizing symptoms, social competence, and language development at 24 months. Participants (n = 292 mothers)…

The present study assessed both concurrent and early influences of the maternal caregiving environment to examine unique contributions of each to variation in children's emotional responses to COVID-19 pandemic. Preschoolers (3-5 years; M = 4.12, SD = 0.49) previously assessed in infancy, several years prior to pandemic outbreak, were re-assessed…

This study investigated whether infants encode better the features of a briefly occluded object if its movements are specified simultaneously by vision and audition than if they are not (data collected: 2017-2019). Experiment 1 showed that 10-month-old infants (N = 39, 22 females, White-English) notice changes in the visual pattern on the object…

Longitudinal associations between signaled night awakening and executive functioning (EF) at 8 and 24 months in children with ([greater than or equal to] 3 awakenings, n = 77) and without parent-rated fragmented sleep ([less than or equal to] 1 awakening, n = 69) were studied. EF was assessed with the Switch task at 8 and 24 months. At 24 months,…

This prospective study examined the latent growth trajectories of sensory patterns among a North Carolina birth cohort (N = 1517; 49% boys, 87% White) across infancy (6-19 months), preschool (3-4 years), and school years (6-7 years). Change rates of sensory hyper- and hyporesponsiveness better differentiated children with an autism diagnosis or…

Adults recognize emotions conveyed by bodies with comparable accuracy to facial emotions. However, no prior study has explored infants' perception of body emotions. In Experiment 1, 6.5-month-olds (n = 32) preferred happy over neutral actions of actors with covered faces in upright but not inverted silent videos. In Experiment 2, infants…

This study examined the biological processes associated with foster mother-infant bonding. In an examination of foster mother-infant dyads ("N" = 41, mean infant age = 8.5 months), foster mothers' oxytocin production was associated with their expressions of behavioral delight toward their foster infant and their average P3 response to…

Associations among 53 primiparous women's Adult Attachment Interview classifications (secure-autonomous vs. insecure-dismissing) and physiological and self-reported responses to infant crying were explored. Heart rate, skin conductance levels, and respiratory sinus arrhythmia (RSA) were recorded continuously. In response to the cry,…

Different social experiences help children develop distinctions between domains of norms. This study investigated whether mothers respond differently to moral, prudential, and pragmatic norms during the 2nd year, a period that precedes the time when children are able to make explicit distinctions between these norms. Sixty mothers of infants…

Young infants respond to positive and negative speech prosody (A. Fernald, 1993), yet 4-year-olds rely on lexical information when it conflicts with paralinguistic cues to approval or disapproval (M. Friend, 2003). This article explores this surprising phenomenon, testing one hundred eighteen 2- to 5-year-olds' use of isolated pitch cues to…

Researchers have suggested that as children's language skill develops in early childhood, it comes to help children regulate their emotions (Cole, Armstrong, & Pemberton, 2010; Kopp, 1989), but the pathways by which this occurs have not been studied empirically. In a longitudinal study of 120 children from 18 to 48 months of age, associations…

Parents' physiological regulation may support infants' regulation. Mothers (N=152) and 6-month-old male and female infants were observed in normal and disrupted social interaction. Affect was coded at 1-s intervals and vagal tone measured as respiratory sinus arrhythmia (RSA). Maternal sensitivity was assessed in free play. Mothers and infants…

The early noncry vocalizations of infants are salient social signals. Caregivers spontaneously respond to 30%-50% of these sounds, and their responsiveness to infants' prelinguistic noncry vocalizations facilitates the development of phonology and speech. Have infants learned that their vocalizations influence the behavior of social partners? If…

Infant joint attention has been observed to be related to social-emotional outcomes in at-risk children. To address whether this relation is also evident in typically developing children, 52 children were tested at 12, 15, 24, and 30 months to examine associations between infant joint attention and social outcomes. Twelve-month initiating and…

Sex differences in responsiveness to infants were investigated by comparing the physiological responses of boys and girls in middle childhood and early adolescence with their overt behavioral reactions which were presumed to be more affected by societal norms. Results showed no sex differences on the psychophysiological measures but did reveal sex…
