Skin conductances and galvanic skin responses (GSRs) of learning disabled (LD) children and controls were compared during an habituation task and a simple reaction time task, each preceded by a rest period. The two tasks were methodologically equivalent except that only the latter required an active response. LDs had more rapid decline of basal conductances during rest, more rapid habituation of GSRs during tasks, and slower reaction times. In addition, the active task was more sensitive to GSR habituation differences than was the passive task. The results were interpreted in terms of a general arousal deficit in LD children, although the greater sensitivity of the active task in detecting habituation differences was seen as supporting the proposal that LDs have selective arousal dysfunctions. / Master of Science

Investigations of children's spatial ability have typically looked at performance on laboratory tasks, and none have examined differences between learning disabled and non-learning disabled children. The present study surveyed sixty-seven parents of third and sixth grade children about the types of spatial activities children engage in everyday. Parents of learning disabled and non-learning disabled children were included. Results provided information about the types of spatial activities children engage in and the relationships between participation and performance. Major findings included differences between learning disabled and non-learning disabled children in navigational ability and in the strategies employed in difficult or ambiguous spatial situations. Findings were discussed in terms of the influence learning disabled children's negative self evaluations have on their performance.

The purpose of the study was to establish diagnostic validity for a modified version of the Classroom Adjustment Rating Scale (CARS). To do this, two a priori multivariate contrasts were specified in order to detect differences on the three CARS scales between three groups of pupils. Subjects were 170 normal (NORM), 125 Learning Disabled (LD), and 48 Emotionally Handicapped (EH) elementary age boys who were rated by their classroom teachers. The original CARS was modified by maintaining and adding items that had high correlations with the original three scales of Acting-Out, Shy-Anxious, and Learning Problems. Results with both the CARS and modified CARS (MCARS) indicated a significant multivariate contrast between the NORM group and a weighted combination of the LD and EH groups. Also, a significant multivariate contrast between the LD and EH group resulted for the CARS and MCARS. Follow-up with discriminant analysis found 71.4% of all boys correctly classified by the original CARS scales. However, the MCARS scales resulted in only a slight improvement in overall correct classification, with 72.3% of boys correctly classified. Teacher-judged intelligence, social class, and prosocial classroom behavior were included as possible biasing variables. It was found that the set of prosocial items had considerable impact on the ratings of EH boys, thus demonstrating the importance of including positive behaviors on a rating scale.
