The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

The success of human culture depends on early emerging mechanisms of social learning, which include the ability to acquire opaque cultural knowledge through faithful imitation, as well as the ability to advance culture through flexible discovery of new means to goal attainment. This study explores whether this mixture of faithful imitation and…

This study examined dispositional and situational correlates of donating behavior in a sample of 221 eight-year-old children. Children were shown a promotional clip for a charity, including a donation call. For a random half of the children, the video fragment ended with a probe of a same-sex peer donating money to the charity. Seeing a peer…

This study investigated the differences in peer preference, gender and temperamental characteristics of children aged five to six in relation to their social competence (SC) and behavioural adaptation. The data were collected through the use of "Picture Sociometry Scale", "SC and Behaviour Evaluation Scale" and "Short…

This study was aimed to investigate the rate of co-occurring sensory processing (SP) dysfunction in children with autism who had a difficult temperament characteristics, and the relationship between SP dysfunction and temperament characteristics in preschool children with autism. A total of 111 children aged 48-84 months, 67 children with autism…

We explored the role that exogenous and endogenous competitors for attention play in infants' abilities to encode and retain information over a 6-month period. Sixty-six children visited the laboratory at 15 months, and 32 returned for a second visit at 21 months. Children observed models of conventional- relation and enabling-relation action…

The present study examined the influence of children's experiences during non-maternal childcare on their behavior toward unfamiliar peers. Participants included children classified as negatively reactive at four months of age (N = 52) and children not negatively reactive (N = 61), who were further divided into those who experienced non-maternal…

Using an experimental approach, our study examined the differentiated effects on pre-schoolers' social cognition of two short-term social information processing (SIP) and Theory of Mind (ToM) training sessions dealing with emotions and beliefs. The links between ToM, SIP, and social adjustment or externalizing behavior were examined. 47…

The present study explores the bidirectional associations between parental behavior and child externalizing behavior in the context of two intervening variables: child's personality as a moderator of the effect of parental behavior on later child behavior; and parental self-efficacy as a mediator of the effect of child behavior on later parental…

This study examines the early emergence of sensory reactivity and novelty awareness and their relations to children's behaviours with peers. A total of 260 parents (242 mothers, 18 fathers) and 10 teachers of 260 children (131 male, 129 female; M?=?63?months; SD?=?8.80; range?=?39-81) participated. Structural equation models indicate that sensory…

Parental depressive symptomatology has consistently been linked to child maladjustment, but these effects are not universal. This investigation examined the role of child temperament as a moderator of the effects of parental depression on behavior problems in five-year-old children. Parents reported on their own depressive symptoms, and both…

The present study was designed to examine cross-cultural differences in longitudinal links between infant temperament toddler behavior problems in the U.S. (N= 250) and Russia (N= 129). Profiles of risk/protective temperament factors varied across the two countries, with fewer significant temperament effects observed for the Russian, relative to…

A number of studies, both small scale and of nationally-representative student samples, have reported substantial associations between school entry math ability and later elementary school achievement. However, questions remain regarding the persistence of the association between early growth in math ability and later math achievement due to the…

Parent-reported reactions to children's negative emotions and child negative emotionality were investigated as correlates of internalizing and externalizing behaviors. Children (N = 107) and their parents participated in a short-term longitudinal study of social development. Mothers and fathers independently completed questionnaires assessing…

The present work addresses the associations between self-reported maternal parenting behaviours and aggression, personality and peer regard of children (n = 119) in early childhood (ages three-six years). A k-means cluster analysis derived types of mothers based on their relative use of autonomy support and restrictive control. Outcomes included…
