Infants of 12 months were tactually familiarized with either a hard or an elastic substance. Subjects subsequently were shown films of objects moving in patterns characteristic of either hard or elastic objects, and their eye movements were detected. Results suggested that quite young infants detect intermodel invariants specifying some substances…

Infants, preschoolers, and adults were tested to determine the shortest time interval at which they would respond to the precedence effect, an auditory phenomenon produced by presenting the same sound through two loudspeakers with the input to one loudspeaker delayed in relation to the other. Results revealed developmental differences in threshold…

One experiment examined two and one-half, three and one-half and four and one-half year olds' ability to conduct nonredundant comprehensive searches of small lidded trash cans. A second experiment examined three , four, and five year olds' ability to find Easter eggs hidden on a large playground. Results were discussed in relation to developmental…

Three longitudinal studies were conducted to examine the generalization of detour ability across motor responses and barrier types, and to investigate the relationship between the development of object permanence and detour ability. Results were discussed in terms of differences in reaching and locomotor detour performances. (Author/CI)

Two experiments evaluated predictions derived from a cognitive-developmental approach to delay of gratification. In the first, kindergarten children were asked to make a choice between a small immediate and a large delayed reward. In the second, children were presented with either an objective-rational or a subjective-emotional argument…

Causal interpretations of story characters' helpful behavior were examined in first, fourth, and sixth graders, and in college-age students. Subjects heard stories featuring actors' anticipations of eight different consequences for helping. Differences in ratings of actors among age groups were discussed. (Author/CI)

Early developmental changes in children's understanding of causality were examined in two studies of three and five year olds' causal judgments. In both studies, children were asked to judge which of two stimuli caused an observed event across a series of problems providing a variety of alternative cues. (Author)

A recognition measure of Kohlbergian moral reasoning, developed on the basis of a production measure, was psychometrically evaluated. Results showed that the Sociomoral Reflection Objective Measure has acceptable concurrent validity and high levels of test-retest reliability and internal consistency. (Author/CI)

The effectance motivation of 624 sixth graders was assessed on the basis of two measures completed by teachers. Student were also observed for their choice of hard and easy problems after being informed of contingencies based on the correctness of solutions. (Author/CI)

Two studies investigated two groups of young children at the ages of four and eight years, respectively. Subjects were required to solve a simple problem task by performing a response opposite to that demonstrated by an adult. Girls' performance was significantly worse than boys', regardless of the sex of the model. (Author/CI)

In the studies, subjects from different age groups (5-6, 7-8, 9-10, 18-22 years) observed vignettes designed to reveal an actor's abilities or personality traits, and were told about one instance of an actor's behavior, respectively. The subjects were then asked to predict the actor's behavior in related situations. Results focused differences in…

Children between the ages of six and 11 were asked to recall personal experiences of pity, anger, and guilt and to rate the cause of each emotion on degree of controllability. Results were interpreted as evidence that guilt in young children may be a qualitatively different emotion because of its closer link to outcome than to perceived…

Reports the results of structured interviews with mothers of 29 children three and one-half to 12 years of age, documenting the development of four categories of food rejection based on distaste, danger, disgust, and inappropriateness. Suggests that lack of contamination sensitivity in younger children is due to their belief that chemical…

Thirty Black, Caucasian, and Mexican-American undergraduates rated photographs of infants of each race on physical attractiveness and 12 bipolar adjectives. Results indicated that strong expectations that "beauty-is-good" are elicited soon after birth for Caucasians and non-Caucasians. Activity in babies appears to be a negative characteristic.…

Compares the responses of 65 mothers and 42 fathers who completed the Child Rearing Practices Report first when their child was three years old and again at 12 years. Despite many changes in the families, considerable continuity in childrearing orientations was shown. Shifts in emphasis coincided with developmentally appropriate areas for change.…
