Differential cue utilization by males and females in pattern copying.

Previous research on pattern copying indicates that male performance improves when reference cues are added to the task, but that female performance remains unaffected by the additional information. Results of experiment 1 reveal that it is the presence of cues in the modeled pattern, rather than on the drawing sheet, that is primarily responsible for the improved copying accuracy. The data also replicate the differential cue utilization by male and female 10-year-olds. Experiment 2 found no such differential performance with a 7-year-old sample. The findings are considered relative to other visual-spatial research.

Simulating conditions of child abuse in the laboratory.

A child abuse analog was created by placing an adult in a frustrating teaching situation with a child learner. The child's performance was programmed to deteriorate despite the adult's teaching efforts. The intensity of the adult's responses used to terminate the child's signals of success or failure was examined over the course of the interaction. The magnitude of these responses increased over trials, particularly in response to signals of failure, and these increases occurred without the adult's awareness. The findings were considered within the context of a social interactional model of child abuse, in which the adult's aggressive behaviors were presumed to result from arousal generated by the child's aversive behaviors.

Sex differences in pattern copying: spatial cues or motor skills?

Accuracy of pattern copying was studied in male and female 10-year-olds. It was hypothesized that previous research reporting male superiority on this measure may have actually reflected the gross-motor skills requirements of the task. The use of smaller stimuli was predicted to eliminate or reverse this sex difference. In addition, visual reference cues were included on some trials to examine their potential facilitation effects. Contrary to expectations, males benefited from spatial reference cues whereas females did not, independent of stimulus size.
