Learning disabilities and intelligence test results: a model based on a principal components analysis of the WISC-R.

The unrotated principal components analysis of the WISC-R normative data yields a bipolar factor 2 which corresponds to a verbal-non-verbal continuum of test material. A review of published WISC-R and WISC data from learning disabled (LD) children reveals that the amount of deficit shown by these children on any particular subtest is closely proportional to the degree of verbal content, as expressed by the factor 2 score coefficient of that subtest. This test-specific effect was found to be very much greater in LD boys than in LD girls.

Handedness, sex and intelligence.

On the basis of data from a large and representative population (N = 1880), we have now had the opportunity to examine the relationships that have been claimed to exist between handedness, sex, and the patterning of intellectual abilities, as these are reflected in performance on the Wechsler Adult Intelligence Scale--Revised (Wechsler, 1981). Such relationships had previously been studied using rather small samples of men and women. Our analyses show a reliable, if negligible, effect of sex on these test results, but no effect of handedness.

Electromyographic biofeedback and physical therapy of the hemiplegic upper limb.

A long-term, comparison-group outcome trial with a partial crossover design was carried out on the effects of electromyographic biofeedback (EMGBF) plus physiotherapy (PT) versus PT alone in the treatment of the hemiplegic upper limb in stroke patients who were at least six months beyond the onset of their disability. Both the experimental and the control groups benefited from their treatment, but EMGBF was shown to have an additional effect, both in the experimental patients, and in the control patients when they switched over to the experimental treatment condition.

Sex differences in the cognitive effects of unilateral brain damage: comparison of stroke patients and normal control subjects.

Our original paper on the influence of the sex of the patients on the cognitive effects of unilateral brain damage mainly described the differences found between the various lesion groups (left/right, male/female) and said little about comparisons between these groups and our control subjects. Such comparisons are examined here; they confirm that the major sex differences after such brain damage appear in tasks intended to involve nonverbal processing. This evidence supports the hypothesis that women, to a greater extent than men, may employ verbal, left hemisphere processing to solve ostensibly nonverbal problems.

Sex differences in the cognitive effects of unilateral brain damage.

One hundred subjects (50 men, 50 women), of whom 80 had suffered a unilateral cerebrovascular accident (40 left, 40 right), were tested on the WAIS. In the case of left hemisphere damage the male patients showed lower Verbal than Performance Scale IQ scores; for the right brain damaged men Performance Scale scores were Lower than their scores on the Verbal Scale. Women with unilateral brain damage showed no such reliable discrepancies between their Verbal and Performance Scale scores. This difference in the patterning of WAIS IQs in male and female stroke patients persisted even after the scores of those few patients with any significant degree of expressive aphasia had been excluded from consideration.

Sex differences in the effects of unilateral brain damage on intelligence.

A sexual dimorphism in the functional asymmetry of the damaged human brain is reflected in a test-specific laterality effect in male but not in female patients. This sex difference explains some contradictions concerning the effects of unilateral brain damage on intelligence in studies in which the influence of sex was overlooked.

Fetal breathing movements in uncomplicated pregnancies. I. Relationship to gestational age.

Fetal breathing movements occur in uncomplicated gestations. The relationship of fetal breathing movements recorded in 30 min sessions to gestational age and blood glucose levels is described. A total of 142 recording sessions were obtained from 45 gravid women with uncomplicated pregnancies from 24 to 41 weeks' gestation. There was a significant increase in the proportion of time spent in fetal breathing as gestational age increased. Glucose levels in a normal range (70 to 120 mg/100 ml) at the time of the recording sessions showed no correlation with the proportion of fetal breathing time.

Maternal ethanol ingestion and the occurrence of human fetal breathing movements.

The study of the development of fetal breathing movements in human gestation may provide an increased understanding of maturation of the functional central nervous system (CNS). In seven term pregnancies low maternal blood alcohol levels suppressed fetal breathing movements. No effects on fetal oxygenation or acid-base status were demonstrated at the low blood alcohol level. The suppression is therefore most consistent with a direct effect of alcohol on the fetal CNS. This investigation provides further support of the thesis that fetal breathing movements reflect some components of fetal CNS activity.
