Developmental differences in empathy with a television protagonist's fear

An experiment was conducted to determine whether children at different ages (3-5 vs 9-11) differ in their tendency to share the emotion of a television character. Subjects were shown a videotape of either a frightening stimulus alone or a character's fear in response to a threatening stimulus that was suggested rather than shown directly. Contrasting predictions were made based on a cognitive-developmental view of the process of empathy vs an automatic conception. Both self-reported emotional reactions and physiological responses were consistent with the cognitive-developmental approach: The younger children were less emotionally aroused by the character's fear than by the fear-provoking stimulus, while the older children responded emotionally to both versions of the videotape. The younger children's lack of empathy was not due to a failure to recognize the nature of the character's emotion. There was some evidence that the older children exhibited a greater tendency to role take than did the younger children.     

Purdue pegboard performance of disabled and normal readers: Unimanual versus bimanual differences

Differences between dyslexics and controls in the unimanual and bimanual conditions of the peg placement section of the Purdue Pegboard Test were examined. Twenty-three disabled and twenty-three normal readers were studied. The groups were carefully screened on a neuropsychological battery. The disabled readers were comprised of a relatively homogeneous language-disordered subgroup exhibiting deficits in naming. Significant Group X Condition interactions were obtained for both raw and percentile scores and indicated that disabled readers performed worse than controls in the unimanual compared to bimanual conditions. The dyslexics performed particularly poorly compared with controls on the left hand condition. The implications of these data for hypotheses which argue for left hemisphere dysfunction, as well as those which posit interhemispheric transfer deficits in reading disabled children, are discussed.     

Reversible operations in the balance scale task

The development of two types of reversible operations was examined in three tasks involving a two-armed balance scale. The first type of reversible operation, compensation between dimensions, was shown to undergo considerable development between eighth grade and college. Even eighth graders were inconsistent in applying compensation to those versions of the balance scale task that required it. Some subjects, primarily preschoolers, used the given information in a way that was the opposite of that required for correct answers, a result that has been reported for other tasks requiring compensation. A second type of reversible operation, termed “correspondence of patterns”, was also tested and it was tentatively concluded that the responses of the modal college student are not fully reversible in this sense. This finding is also similar to results obtained in judgments of time, speed, and distance and in social judgment studies with college students.     

Image tracing: An analysis of its effectiveness in children's pictorial discrimination learning

Previous research has shown that requiring children to trace from memory the correct member of a pictorial discrimination pair markedly facilitates performance. The experiment reported here offers support for a presumed component of this learning strategy, namely, “memory imagery.” In particular, subjects who traced directly on top of the correct picture did not perform as well as those who traced it from memory. Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding, and frequency.
