Process praise (i.e., praise for effort) facilitates childhood persistence. However, less is known about the mechanism by which process praise influences persistence in infancy. Here, we propose that well-timed process praise reinforces the link between effort and success, thus promoting persistence in young children. In Experiment 1, U.S. infants…

A growing body of literature has established longitudinal associations between key social cognitive capacities emerging in infancy and children's subsequent theory of mind. However, existing work is limited by modest sample sizes, narrow infant measures, and theory of mind assessments with restricted variability and generalizability. The current…

This study aimed to investigate how mothers and infants contribute mutually to breastfeeding. The spontaneous interactions of 20 breastfeeding dyads were video-recorded at home, at 2, 4, 6, 9 and 12 months of infants' life. Mothers' and infants' gaze and tactile behaviour, facial expressions of emotion, and dyadic expressions were continuously…

Two experiments investigated the role of distractor characteristics and type of object-directed attention on 7- and 10-month-old infants' distraction latencies during object exploration. Found that infants took longer to turn toward distractors during focused object-directed attention than when engaged in more casual attention. They exhibited…

Examined the relationship between infant attractiveness and maternal behavior by observing mothers feeding and playing with their firstborn infants immediately after giving birth and when the infants were three months of age. Found that mothers of more attractive infants were more affectionate and playful compared with mothers of less attractive…

The results obtained by researchers interested in the speech-time relationship indicate that the sequential organization through time of speech sounds necessary for communication requires a universal "grammar" consisting of vowel and consonant sequences and an awareness of the duration experienced in that process, as well as the memory…

In a study to assess young children's social interaction with peers, six male toddlers who were the only participants in a playgroup were observed in two situations: (1) a GROUP situation in which at least four of the boys were present and (2) a DYAD situation in which only two boys were present. Both types of observations were made at 16, 19, and…
