Findings from two studies of 42 children with profound developmental delays (26 males and 15 females) using systematic and intense response-contingent learning opportunities interventions are reported. Response-contingent learning games were used to promote the participants' use of behavior that either produced environmental consequences or…

The influence of peer models on changing the impulsive response styles of fourth and sixth grades was experimentally investigated. (DP)

Examined whether children who vary in their behavioral responses to ambiguous provocation but have similar attributional processes differ in their social goals and self- efficacy perceptions. Subjects were 781 4th and 5th graders. Found that aggressive, withdrawn, and problem-solving responders differed in the social goals and self-efficacy…

This paper reports research studies on the determinants of children's helping of another child in distress. Effects of age and various environmental conditions were investigated. Experiments had a similar design: subjects were given a task and made aware that a child was alone in an adjoining room. The experimenter then left the room and subjects…

FOR 5 WEEKS, 2 OBSERVERS MADE DAILY VISITS TO A LABORATORY PRESCHOOL TO COLLECT INFORMATION ON THE AMOUNT AND KINDS OF POSITIVE SOCIAL REINFORCEMENT CHILDREN GIVE TO EACH OTHER IN NURSERY SCHOOL. SEVENTY CHILDREN (AGED 3 YEARS 4 MONTHS TO 4 YEARS 9 MONTHS) WERE GROUPED INTO 2 OLDER AND 2 YOUNGER CLASSES. EACH CHILD WAS OBSERVED IN RANDOM ORDER FOR…

Fixation time, smiling, vocalization, and fret/cry were recorded to obtain a complete picture of infants' responses to facial stimuli over the first year of life. Four stimuli were presented to 120 infants. Results of fixation data indicate that (1) there is a marked decrease in fixation toward facial stimuli within the first year, (2) at all ages…

This report summarizes four components of a research program. In the major investigation (Study 1), a method was developed for making bimodal presentations of discrepant auditory and visual stimuli under conditions which approximately early academic tasks. The goals were to determine (1) which stimulus modality exerts the greater influence on a…

In this study an attempt was made to measure variables which were expected to be related to individual differences in infants' social responsiveness toward strangers. The subjects were 48 infants (24 boys and 24 girls) between 8 and 13 months of age. Most were children of Cornell University faculty or graduate students, but a broad range of…
