Hong Kong Chinese and American adolescents were given three Piagetian tasks of formal operations in order to assess cultural, age, and sex differences. Significant effects were demonstrated with Americans, older subjects, and males performing at more advanced levels. (Author/JMB)

The present findings suggest that never" as a response and very often" as a response are mediated by different underlying processes, at least between the ages of 8 and 17. (Author/WY)

Findings of the present inquiry indicate the relevance of cognitive considerations in studies of time perception. (Authors)

Examined association of individual differences in physical maturation with information-processing speed among 9- and 10-year olds. Found that early maturers were faster than late matureres, although this maturity effect was primarily the result of a significant effect for boys. The early maturers' faster processing times may be specific to boys or…

Exploring issues of content and construct validity, this paper reviews how empathy in young children has been defined and measured. Discussion first focuses on empathy viewed as an affective awareness and response to the feelings of another person. The review reports research using the Affective Situation Test, naturalistic studies of affective…

Traces the developmental history of information processing in elementary school children as measured by a numerals-keys choice response paradigm. Also attempts to correct some of the more obvious methodological problems observed in previous students of this type. (Author/MP)

During individual interviews, each of 64 subjects, aged 8 to 14, generated a peer perception grid in which 17 supplied figures were rated on 10 individually elicited bipolar concepts. Three aspects are examined: attributional characteristics of concepts, level of differentiation between peer figures, and organizational complexity of relations…

This study investigated the developmental patterns for 82 deaf individuals (9-19 years old) in field dependence, as measured by the Embedded Figures Test. A significant sex difference was found for these deaf subjects only at the age of 15, favoring males. The deaf subjects differed significantly from the hearing norm group only at ages 15 and 17.…

Subjects were 72 first, third and fifth graders. Stimuli consisted of an initial set of 20 unrelated pictures, and a second set of 20 pictures which could be classified according to four superordinate categories. (MS)

A study examined the relative contributions of age, sex, and education to verbal and nonverbal fluency in a normal population. Sixty-seven subjects aged 12 to 71 years performed paper-and-pencil tasks proven to be dependent on the right and left hemispheric modalities of the frontal lobes. Multiple t-tests were applied to determine whether…

The purpose of this study was to identify conflict resolution strategies used by siblings when they chose television programs to watch and to examine differences in strategies associated with sex of child, the age interval between siblings, and their ordinal position. Children, 116 pairs of siblings in first through sixth grade, were interviewed…

The purpose of this followup electromyographical study was to gain further insight on previous research findings indicating that subvocal speech is significantly correlated with recall for preschool boys but not for girls. Twenty-two preschool children (11 boys, 11 girls; 50-67 months old) participated in 12 trials using high-labial and low-labial…

Three different analyses have shown that the more information available in a nonverbal decoding task, the less efficiently younger subjects utilize the information relative to older ones. This differential effectiveness in the utilization of available information was discussed in terms of processing capacity, effort, and strategies for sampling a…
