Comparability of the WISC and the WISC-R in normal children of divergent socioeconomic backgrounds

WISC and WISC-R IQs of two groups of normal ten-year-old children from divergent socioeconomic backgrounds (N = 36) were compared in a counterbalanced research design. Generally, all WISC mean IQs were higher than the WISC-R mean IQs for both groups of children. Significantly higher WISC IQs were obtained on the Verbal and Full Scales of the low socioeconomic group and on the Performance and Full Scales of the high socioeconomic group. Correlations between tests for Verbal, Performance, and Full Scale IQs were.95,.79, and.91 for the low socioeconomic group, and.84,.57, and.87 for the high socioeconomic group. Although practice effects did not appear to significantly affect IQs of the low socioeconomic group, various practice effects were observed in the high socioeconomic group. Negative effects were observed for both WISC and WISC-R on the Verbal Scale, whereas positive effects were observed on both Performance and Full Scales in this group. Analysis of simple effects reveals that WISC and WISC-R IQs did not differ significantly upon first administration, but were significantly different upon second administration. Conclusions were drawn that while WISC-R yields a lower IQ estimate than WISC for children of lower ability, results were not so clear for the children of higher ability, due to practice effects which disproportionately favor increases on WISC IQs upon second administration. The greater practice effects found on the WISC have implications for comparisons of the two tests in counterbalanced research designs. Simple randomized or treatment-by-levels design may be more useful in comparisons of the WISC and the WISC-R because of the bias introduced by counterbalanced designs.     

Behavior ratings of emotionally disturbed children by teachers,parents, and school psychologists

Emotional disturbance was rated by teachers, parents, and the school psychologist for a group of 104 children diagnosed as severely emotionally disturbed. Teachers were found significantly more severe in their judgments than the school psychologist on the Behavior and Socialization scales of the Referral Checklist, but not on Communication. The teacher rating profile was also found to deviate from parallelness from the other raters with increased severity in the Behavior scale. None of the nine correlations between judges on the same scales was significant. Interpretations and possible implications are offered.     

The others-concept and friendly and cooperative behavior in children

This study explored the predictability of friendly, cooperative behavior of school children over a 5-week period. The basis for the predictions was the children's others-concept, as measured by the Paired Hands Test. Structured observations of groups of children working together on assigned tasks were made during five consecutive weekly sessions, each lasting approximately 15 minutes. The observations were obtained by recording each session and categorizing verbal statements as to their task-relatedness and friendliness. This procedure allowed comparisons between children with high and low others-concepts with respect to these behaviors. In three tasks out of five the high others-concept children showed a higher frequency and greater proportion of task-related and friendly behaviors. The tasks which best differentiated between children with high and low others-concepts were those which seemed to be the most challenging and exciting, and which called for the highest degree of group cooperation. The study demonstrated how friendly and cooperative interactions among small groups of children are influenced by a combination of their others-concept and situational factors.
