Findings indicated that among children between 15 and 35 months observed in a series of play and clean-up tasks, there was a consistent developmental pattern in the extent to which they focused on producing outcomes, and monitored, corrected, and controlled activities, and in the frequency with which they reacted to their outcomes with positive…

Infants who cried in response to a reward shift evidenced no retention of the contingency 1 week later but did have excellent retention at one day. Reactivation treatment alleviated forgetting at three weeks. Results indicate that crying in response to violation of a reward-expectation habit functions as an amnesic agent to produce accelerated…

Data indicate that for girls, affective dispositional factors (empathy, depressive affectivity, aggression, and self-concept) are intimately linked to cognitive development and academic achievement. (PCB)

Mothers of 48 infants approximately 12 months old displayed either positive or neutral affect while their infants responded to pleasant, ambiguous, or aversive toys. On the first trial maternal affect had no effect; on the second trial, positive maternal affect resulted in more positive infant responses, but only for the ambiguous toy. (Author/RH)

Studied were the responses of infants to new toys presented with either positive, negative, or neutral affective displays by mothers. Responses to stimulus toys were compared with responses to free play toys. Maternal displays influenced responses only to stimulus toys. (PCB)

A two-part study examined children's conceptions of the linkages between sociomoral events and emotional consequences for several event participants. Results of the first study indicated that children's conceptions were highly differentiated. The second study found children able to match affective information to events likely to cause emotional…

Results indicated that the more frequently the children studied expressed emotion, the older the age of language achievements; and the more time spent in neutral affect, the younger the age of language achievements. (PCB)

Documents rate, mean duration, and mode of infants' affective displays. Using cross-sequential design, observes infants in their homes from 6 to 18 months playing with their mothers, with peers, and alone. With increasing age, affect rates and vocal modes increased, and mean durations and facial and motoric modes decreased. (Author/BE)

In this study, in which triads of children were filmed while they played with a toy, the relation between (1) preschoolers' emotional status and (2) their performance and receipt of prosocial behaviors was examined. (PCB)

A group of 20 abusive mothers and a group of 20 matched, nonabusive mothers were shown slides depicting infants in seven different emotional states. Abusive mothers were more likely to incorrectly identify specific signals of emotion and to label negative affect as positive. (Author/RH)

Quantifies behavioral periodicities or cycles during face-to-face interaction between three- and five-month-old term and preterm infants and their mothers. Compares the temporal organization of social interaction between term and preterm infants. Spectral and cross-spectral techniques showed the existence of periodicities. Differences were found…

Evaluates the extent to which 54 infants aged three, six and nine months and their mothers were able to coordinate their behavior. Results indicate that mother-infant pairs increase their degree of coordination with infant age, but the proportion of time they are coordinated is small. (RJC)

The study attemped to link cognitive and social problems seen in girls with Turner syndrome by assessing the girls' ability to process affective cues. Seventeen 9- to 17-year-old girls diagnosed with Turner syndrome were compared to a matched control group on a task which required interpretation of affective intention from facial expression.…

Relations among hormone levels, emotional dispositions, and aggressive attributes were examined in 56 boys and 52 girls, aged 9 to 14 years. (PCB)

Findings indicated that (1) when siblings were 24-months-old, their social-emotional behavior displayed some concordance, and maternal behavior was stable with all siblings; (2) significant concordance in siblings' social-emotional behavior was conditioned by stability of maternal behavior; and (3) quality of infant-mother attachment at 12 months…
