This study attempted to determine empirically the influence of visual perceptual remediation on drawing utilizing educationally handicapped children of elementary age as subjects. The 34 girls and 78 boys were of average intelligence, with one-half of the subjects evidencing measured visual perceptual dysfunction. In each experimental group, 14 visual perceptually impaired (learning disabled) and 14 non-perceptually impaired (learning disordered) children received instruction on one of three commercially available visual perceptual remedial materials, Controls (28 subjects) received no special training. Prior to the training, subjects' drawings were collected, as well as after the 12-wk. intevention period by five graduate students in art education. The analysis of variance used to determine the effects of the intervention program on seven specified descriptors of drawing behavior yielded only one statistically significant descriptor, "Non-awareness of Social Situations and Self vs Awareness of Social Situation and Self." There were no differences between the perceptually impaired and non-impaired subject groups on any of the drawing tasks.
There is a need to determine the extent to which the "Background Interference Procedure" as an adjunct to the Bender-Gestalt can account for criterion variance beyond that level predicted by an optimal battery. Discriminant functions empirically classified subjects into clinical categories of learning disability. A reduced battery of intellective and visual-motor predictors generated two significant functions, accounting for 91% of the variance. The first dimension reflected over-all intellectual functioning, the second, psychomotor skills. Empirical classification accurately categorized 71% of all subjects across five criterion groups. The functions efficiently separated the criteria, but the six Background Interference Procedure predictor variables did not improve prediction. Implications include using the Background Interference Procedure for early screening of learning disabilities and employing discriminant functions for data reduction and construct validation of teachers' and judges' ratings.
Practice effects within a multiple-phase administration of the Bender Visual-motor Gestalt Test were investigated. The addition of a 5-sec. Flash phase prior to the standard presentation did not significantly influence performance on the standard presentation. Students who attempted both the Flash and standard administration prior to a recall phase remembered significantly more designs than students receiving only the standard administration prior to recall. Those skills possibly measured by the multiple phase Bender format are discussed and the need for research using the three-phase method is suggested.

The Bender-Gestalt protocols of 134 rural and 140 urban slow learners (IQ 70 to 84) are compared. Rural slow learners performed significantly below their mental ages more frequently than urban slow learners. Rural and urban slow learners performed developmentally below chronological ages, but as expected for mental ages until CA 10 (MA 8). At this point urban slow learners appeared to perform as expected from MAs, but a significant number of rural slow learners performed below expectations. After CA 14 (MA 11-0) the differences between the urban and rural groups, however, were not significant.

The purpose of the present work was to evaluate the clinical course of epilepsy with infrequent partial attacks with complex manifestations derived from the temporal lobe. Thirty patients aged 14 to 64 years treated on an outpatient basis and discovered during epidemiological investigations were followed-up. In half the cases only attacks without generalization occurred, in the remaining cases isolated generalized seizures appeared during many years of disease duration. In both groups a decrease was observed in the frequency of seizures in patients treated systematically or irregularly, as well as in those who had never been treated. Despite a long duration of the disease (above 6 years in 24 cases) the patients had normal mental level and good social adaptation.
Progeny of women, whose thyroid function was studied gestationally, had psychological and/or neurologic examinations at 8 months, 4 years and 7 years of age. In more than 100 pregnancies (at least 3 per cent of total pregnancies) hypothyroxinemia occurred and was treated adequately or inadequately. Children were delivered after uncomplicated pregnancies (except hypothyroxinemia), had birth weights of at least 2,500 grams, and were excluded when postnatal insults intervened. At 8 months and 4 years progeny of inadequately treated hypothyroxinemic women had the lowest psychological scores. Now 246 7-year-old children have been examined psychologically and neurologically (earlier data on only 101). Definite trends and a few statistically lower psychological scores of progeny of inadequately treated hypothyroxinemic pregnant women are compared with better psychological scores of 7-year-old children born to euthyroid and adequately treated hypothyroxinemic women. In six sibling sets outcome was better when hypothyroxinemic women were treated with adequate thyroid replacement therapy. If a woman has a poor reproductive history, early in a subsequent gestation, thyroid status should be examined and adequate thyroid medication considered seriously.

Hyperactive children (N = 15) and nonhyperactive children (N = 15) were compared. Hyperactive children were found to possess significantly higher (p less than .002) muscular tension levels and, in addition, presented more behavioral problems and had lower test scores. Both electromyographic (EMG) biofeedback and progressive relaxation exercises were successful in the significant reduction of muscular tension, hyperactivity, distractability, irritability, impulsivity, explosiveness, aggressivity, and emotionality in hyperactive children. The greatest improvement was seen in the area of "emotionality-aggression" (irritability, explosiveness, impulsivity, low frustration tolerance, aggresion). No differences were seen in the EMG improvement of drug and nondrug hyperactive children; both made progress under these self-control techniques. However, nondrug children made greater improvements in the behavioral area. Both EMG biofeedback and progressive relaxation resulted in improvements on the test scores of hyperactive subjects (Bender-Gestalt, Visual Sequential Memory, Digit Span, Coding). The therapy would appear to be improved by the inclusion of mental relaxation, concentration, meditation, and mind-blanking exercises for mental control.
