Verbal Performance

This study investigated the diagnostic usefulness of WISC-R Verbal-Performance IQ discrepancies, subtest scatter, and Bannatyne's subtest recategorizations with educationally normal and exceptional groups of children. The subjects for this study were four groups of 74 learning disabled, 24 mentally retarded, 94 gifted, and 85 educationally normal children. No significant differences in discrepancies in Verbal-Performance IQs occurred among the four groups although learning disabled children more often showed Performance > Verbal discrepancies. No differences were found between the samples in the amount of subtest scatter. Group differences were noted in the patterns of scores on Bannatyne's recategorizations.

Selection Of

The relationship between the McCarthy General Cognitive Index and the WISC-R Full Scale IQ was examined for 20 educable mentally retarded, 20 learning disabled, and 20 normal children aged 6 to 8½ yr. Selection of children was conducted so that the three groups would be comparable with res pea to age, sex, and race. The mean McCarthy Indexes for the retarded and learning disabled samples were significantly lower than the mean WISC-R Full Scale IQs. When the Index and Full Scale IQ were converted to a common metric and compared, the mean index for the retarded and learning disabled samples remained lower than the Full Scale IQs, although the differences were nonsignificant. The measures correlated significantly for all three samples and ranged from .51 to .82.

Rater Reliability

Inter-rater reliability of the Goodenough-Harris and McCarthy Draw-A-Child scoring systems was examined for a sample of 60 children, including 20 school-labeled learning disabled, 20 mentally retarded, and 20 normal children between the ages of 6 and 8 ½ yr. ( M = 7–8; 44 males and 16 females; 36 whites and 24 blacks). The inter-rater reliabilities of the Goodenough-Harris system were .938 and .934 for the McCarthy Draw-A-Child. The scores from both drawing tests correlated significantly, .57 to .87, with the WISC-R Full Scale IQ and McCarthy General Cognitive Index. Implications are discussed as they relate to the use of the Goodenough-Harris and McCarthy Draw-A-Child systems.

Neurofeedback (NFB) is an operant conditioning procedure, by which the subject learns to control his/her EEG activity. On one hand, Learning Disabled (LD) children have higher values of theta EEG absolute and relative power than normal children, and on the other hand, it has been shown that minimum alpha absolute power is necessary for adequate performance. Ten LD children were selected with higher than normal ratios of theta to alpha absolute power (theta/alpha). The Test Of Variables of Attention (TOVA) was applied. Children were divided into two groups in order to maintain similar IQ values, TOVA values, socioeconomical status, and gender for each group. In the experimental group, NFB was applied in the region with highest ratio, triggering a sound each time the ratio fell below a threshold value. Noncontingent reinforcement was given to the other group. Twenty half-hour sessions were applied, at a rate of 2 per week. At the end of the 20 sessions, TOVA, WISC and EEG were obtained. There was significant improvement in WISC performance in the experimental group that was not observed in the control group. EEG absolute power decreased in delta, theta, alpha and beta bands in the experimental group. Control children only showed a decrease in relative power in the delta band. All changes observed in the experimental group and not observed in the control group indicate better cognitive performance and the presence of greater EEG maturation in the experimental group, which suggests that changes were due not only to development but also to NFB treatment.

Comparisons of the Peabody Picture Vocabulary Test—Revised and the Wechsler Intelligence Scale for Children—Revised were made with 104 children diagnosed as learning disabled and mentally retarded. Significant but modest correlations were found between all but one of the WISC—R scaled scores (i.e., Coding) and PPVT—R standard scores, and between WISC—R IQs and PPVT—R standard scores. Significant differences were found among mean Verbal, Performance, and Full Scale IQs and mean PPVT—R standard scores. The PPVT—R standard scores underestimated WISC—R Verbal IQs by 7 points, WISC—R Performance IQs by 17 points, and WISC—R Full Scale IQs by 11 points.

Mentally Retarded Children

Recent studies of mentally retarded children have found substantially higher rates of color blindness than are usually reported for the general population. In 2 of these studies, sex differences in color blindness, invariably found in intellectually normal children, do not appear. Reanalysis of data from one of the studies of retarded children suggests the possibility that the high rates arise from the difficulty in comprehending the test and following the directions rather than from faulty color vision. However, even if the number of color blind retarded children is actually lower than these studies show, the need for research on this topic seems apparent. Using color dependent instructional materials with color blind, mentally retarded children may be detrimental.

Selected milestone and local programs from Canada and the United States of America are reviewed to illustrate the need to transcend the iatrogenic or socially harmful pseudo-scientific defeatism which often blocks meaningful investment by a community in efforts designed to return mentally impaired persons to normal functioning. The matetial presented attempts to bridge the gap between the specialized literature of psychological research and the very practical interpretations demanded of community psychologists in the field. Local context evaluations and replications are encouraged.
