This study concerned the prediction of group membership of 40 learning disabled and 40 normal children on the basis of preference for laterality of the children and of their parents. A stepwise discriminant analysis showed maternal and paternal lateral preferences could correctly identify approximately 85% of the cases. Orthogonal contrasts showed that, although children themselves did not differ in the degree of laterality, parents of learning disabled children were significantly more bilateral in their preference patterns than normals.

Reliability and predictive validity of the Dean Laterality Preference Schedule with preadolescents.

The reliability and predictive validity of scores of the Dean Laterality Preference Schedule were estimated with 50 preadolescent children. The schedule is a self-report measure of a respondent's lateral preference for a number of common tasks involving the eyes, ears, hands, feet. One week following the administration of the scale, data were collected on each child's lateral preference when performing the actual tasks. Analysis showed the schedule to be a good predictor of manual patterns of lateral preference. The temporal stability of scores was .91 when all subjects were retested 4 wk. after its initial administration. It was concluded that the scale meets minimum requirements of reliability and predictive validity with preadolescent children.

Patterns of emotional disturbance on the WISC-R.

Fourteen WISC subtest patterns that purport to differentiate behavioral disorders were applied to the WISC-R. Forty-one adolescent males referred as a result of conduct disorders were administered the WISC-R. In general, a group analysis showed a depression of verbal functions and satisfactory reliability. The majority of signs investigated were shown to be as effective with nonschizophrenic emotionally disturbed children as with the specific clinical picture they were designed to predict. Evidence pointed to a number of patterns of subtest scatter useful in the diagnosis of a generalized state of emotional disturbance. Implications for clinical practice were discussed.

Mode of input in long-term recognition.

Recent research by Garabedian, Yekovich, Sherman, and Dean has demonstrated that recognition from long-term memory was superior for words presented visually over those presented auditorily. Because their results could have been influenced by the salience of the projected visual items, the present investigation attempted to eliminate the possible visual bias. 16 undergraduates were presented a list of nouns of mixed input modality and were tested 6 min. later for incidental recognition of input mode. The present data corroborated findings by Garabedian, et al. who postulated that subjects use some form of stored visual information when identifying the input mode of words.
