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…

Prosocial behavior in early childhood is a precursor to later adaptive social functioning. This investigation leveraged mother-reported, physiological, and observational data to examine children's prosocial development from age 2 to age 4 (N = 125). Maternal emotion socialization (ES) strategies and children's parasympathetic regulation have each…

Examined the nonnutritive sucking responses of 5- to 15-week-old infants to the contingent and noncontingent presention of natural speech stimuli, the contingent withdrawal of speech stimuli, and the absence of speech stimuli. (Author/JMB)

Results of an experiment with 6-month-old infants showed that response-independent auditory-visual reinforcement can elicit learned responses and that action-consequence learning in infants may consist of a combination of elicitation and conditioning. (Author/JMB)

Modeling techniques and reinforcements for imitation of 35 mothers were recorded as the mothers interacted with their 19-month-old infants in a seminaturalistic setting. Children's imitations and mothers' reinforcements for imitation were found to be complexly related. (GO)

Findings indicate that infant boys may be more easily conditioned by visual reinforcement than are girls. (Author/MB)

Two experiments examined how different frustration contexts affect the instrumental and emotional responses of 4- to 5-month-olds. Both experiments showed that arm responses increased when the contingent stimulus was lost or reduced but decreased when control of the stimulus was lost under noncontingency. Facial expressions of anger, but not…
