The effect of shape of frame on orientation discriminations was investigated for 56 preschool children. (JMB)

Metaphors of similarity and proportionality, together with a pictorial form of similarity metaphors, proverbs, and several Piaget-type cognitive tasks, were given to 50 boys aged 5 through 13 years. Results indicated that metaphor comprehension is a type of classificatory behavior, the development of which is related to maturing cognitive…

Trace conditioning was evaluated in newborn infants by measurements of heart rate responses to a conditioned stimulus in anticipation of or in absence of the unconditioned stimulus. Data suggest females have higher levels of heart rate variability than males, which parallels their greater conditionability. (GO)

Two experiments are reported in which cardiac habituation of the orienting response to pure tone stimuli was studied in well-nourished and malnourished male Guatemalan infants. Results indicated a fundamental attentional deficit in the malnourished group. (GO)

Parents were shown videotapes of boys and girls performing dependent and independent behaviors and were asked how they would respond to the child observed. Interaction process analysis of responses indicated fifferent patterns of responding for fathers and mothers. (GO)

This experiment demonstrated that 12-month-old monkeys reared in social isolation developed appropriate species-typical behavior through the use of adaptation, self pacing of visual input and exposure to younger "therapist" monkeys. A critical period of socialization is not indicated in the rhesus monkey. (GO)

A total of 57 7- and 8-year-old subjects matched on measures of socioeconomic status, locus of control, need for social approval, and self esteem were assigned to two affect conditions and one control condition. Subsequently they were exposed to a resistance-to-temptation task involving play with a forbidden toy. (GO)

The transition from virginity to nonvirginity was studied in high school and college males and females. Virgins were found to differ from nonvirgins on measures of value on achievement, value on independence, available models for deviance, and other factors. (GO)

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)

The ability of preschool and 8-year-old children to recall the spatial location of an event was assessed in three experiments in which familiarity, differentiation, and foreknowledge were controlled. Data were interpreted in terms of Piaget's theory of spatial representation development. (GO)

This study examined the development of three schemes for the attribution of psychological events to multiple causes in children of 5, 9, and 13 years of age. Stories were read to the children and each child was asked to infer possible causes of events. Multiple sufficient and multiple necessary and inhibitory causes were found only in the older…

Relative preference for interacting with people versus objects was observed in 38 children during nursery school free play. Object oriented students were found to perform better on organization and classification of physical objects. Person orientation was not found to be related to performance on tests assessing social knowledge. (GO)

Piaget's and Inhelder's Three Mountain Task and Witkin's Children's Embedded Figures Test were given to a group of 80 Nigerian boys aged 7 through 10 years. (GO)

This study examined the performance of middle aged and elderly adults on the Piagetian tests of class inclusion and multiple classification. (GO)

Simultaneous and successive visual and tactual shape discrimination were examined in this study which replicated with modifications an earlier study. When ceiling effects were precluded, data support the conclusion that children often find it more difficult to discriminate shapes by touch than by vision. (GO)
