Developmental research during COVID-19 suggests that pandemic-related disruptions in family relationships are associated with children's mental health. Most of this research has focused on 1 child per family, thereby obfuscating patterns that are differentially operative at the family-wide (i.e., between-family) versus child-specific (i.e.,…

Infants can help and share in the second year of life. However, there is limited knowledge as to variability in these behaviors as a function of target (e.g., caregiver vs. unfamiliar adult) and the influence of caregiver support on infant prosocial behavior. Infants (N = 268, 124 female) at 1-2 years of age (M = 1.47, SD = 0.27) and again at 2-3…

The extant literature on the use of autonomy support during caregiver-child conversations has focused primarily on conversations about fun, shared experiences, with limited consideration of unshared experiences or attention toward the role of conversation context. The present study examined how autonomy support, conversation context, and child age…

Despite the well-established protective functions of guilt across childhood, its underlying physiological mechanisms have received little attention. We used latent difference scores (LDS) to model changes in children's (N = 267; 4- and 8-year-olds, 51% girls) skin conductance (SC) and respiratory sinus arrhythmia (RSA) while they imagined…

Attachment studies mostly follow the Western middle-class model in theory and methods. To demonstrate that the assessment of children's caregiving context is an often neglected, but crucial prerequisite for attachment studies, we (a) conducted a literature analysis of attachment research in non-Western contexts and (b) empirically investigated the…

This research examined whether infants tested longitudinally at 10, 14, and 16 months of age (N = 58) showed evidence of perceptual narrowing based on face gender (better discrimination of female than male faces) and whether changes in caregiving experience longitudinally predicted changes in infants' discrimination of male faces. To test face…

This study investigated the role of moral emotions in the development of children's sharing behavior (N = 244 4-, 8-, and 12-year-old children). Children's sympathy was measured with both self- and primary caregiver-reports, and participants anticipated their negatively and positively valenced moral emotions (i.e., feeling guilty, sad, or bad; and…

Many child care centers temporarily move children and teachers in and out of their assigned classrooms throughout the day. Such practices create frequent discontinuity in children's experiences in child care, including discontinuity in their peer and teacher relationships. This study examined the prevalence and patterns of teacher and child…

Zimmerman, Christakis, and Meltzoff (2007) reported that exposure to Baby Einstein videos was negatively associated with language development. The current study uses the Zimmerman et al. (2007) data set to replicate and extend the original analyses. Caregivers of 392 children aged 6 to 16 months and 358 children aged 17 to 27 months reported on…

The authors adapted an experimental design to examine effects of instruction prior to entry into a children's museum exhibit on caregiver-child interactions and children's learning. One hundred twenty-one children (mean age = 6.6 years) and their caregivers were randomly assigned to 1 of 5 conditions that varied according to what, if any,…

This exploratory cross-sectional study examined fluid cognitive skills and standardized verbal IQ scores in relation to cultural engagement amongst Tohono O'odham children (N = 99; ages 7 to 12 years). Guardians with higher socioeconomic status engaged their children in more cultural activities, and participation in more cultural activities…

Described experiences of 84 German toddlers enrolled or not enrolled in child care. Found total amount of care per weekday did not differ by child-care status; child-care toddlers received lower care levels from center providers; their mothers engaged in more social interactions during nonworking hours than did mothers of home-only toddlers; and…

Trajectories of children's externalizing behavior were examined using multilevel growth curve modeling of data from the NICHD Study of Early Child Care and Youth Development. According to ratings by both mothers and caregivers/teachers when children were 2, 3, 4, 7, and 9 years old, externalizing behavior declined with age. However, mothers rated…

The relations among specific aspects of language (comprehension, production, semantics, and utterance length), relations between language and symbolic play, and maternal influences were evaluated in mother-toddler dyads when the children were 13 and 20 months of age. Found toddler language ability did not generally predict toddler play and that…

Used an event-based approach to study the nature of coordination in 3- and 6-month olds during interaction with their caregivers. Found that infants coordinated their vocalizations and facial actions more than expected by chance. When two communicative events were temporally associated across modalities, one event tended to be embedded within the…
