The TM-Sidhi programme, age, and brief tests of perceptual-motor speed and nonverbal intelligence.

Three brief tests that assess perceptual-motor speed and two that assess nonverbal intelligence were administered to individuals who were practicing the Transcendental Meditation and TM-Sidhi programme. Multiple regression analyses showed that when motivation (measured on a 5-point self-rating scale), age, sex, education, and duration of practice of the Transcendental Meditation technique were held constant, number of months of practice of the TM-Sidhi programme significantly predicted higher performance on two of the perceptual-motor speed tests and both tests of intelligence. Age predicted lower scores on the same tests.

Changes in seizure frequency and test-retest scores on the Wechsler Adult Intelligence Scale.

Test-retest performance on the Wechsler Adult Intelligence Scale (WAIS) of two groups of adult epilepsy patients are presented and compared. In one group, Seizures Improved (SI) group, seizure frequency had decreased during the test-retest interval, and in the other group, Seizures Unimproved (SU) group, the number of seizures had either increased or stayed the same over the test-retest interval. The SI group showed a significant test-retest improvement on WAIS Verbal IQ, Performance IQ, and Full Scale IQ, as well as on eight of 11 WAIS subtests. In comparison, the SU group showed significant increases only on the Performance IQ and Object Assembly subtest. Furthermore, differences between the two groups were observed in the pattern of test-retest changes seen on the Performance measures relative to the Verbal measures. The results suggest that change in seizure frequency is one of the factors associated with test-retest changes in the intellectual functioning of epilepsy patients.

Intellectual performance of chronic schizophrenic patients.

Intellectual characteristics of 116 male chronic schizophrenic patients were investigated by using the Quick's test of intelligence. Indirectly, by this test the thinking of examinees was analysed. The examinees were divided into age-groups and differentially diagnostic groups. According to age, they were divided into three groups: from 25 to 40, from 41 to 50, and from 51 to 60 years. There were four differentially diagnostic groups: paranoid, catatonic, and hebephrenic patients and patients with schizophrenia simplex. The study has shown that the intelligence of chronic schizophrenic patients, divided into age groups, was significantly different. The average IQ of patients from 25 to 40 years was 82.9, from 41 to 50 years 67.4, and from 51 to 60 years 52.0. The intelligence of examinees divided into differentially-diagnostic groups was also significantly different. The average IQ of paranoid patients was 74.3, of catatonic patients 64.8, of hebephrenic patients 59.2, and of those with schizophrenia simplex 57.4. Most cases with IQ = 0 related to the group with schizophrenia simplex. The willing-instinctive personality sphere and perceptual disturbances in chronic schizophrenic patients appear to exert a significant influence on their intellectual characteristics.

Psychopathology and chronic drug use: a methodological paradigm.

Four carefully matched groups, each containing nine male, chronic users of a specific type of substance, were compared with each other and with a group of nine nonusers. Each person was elaborately studied in a representative case research, but this report presents only data from two tests of intelligence (the Revised Beta and the WAIS) and two tests of personality (the MMPI and 16 PF). Extensive descriptive information is presented to characterize the participants. Groups were found not to differ on scores on intelligence tests, and the MMPI was found to reveal more group differences than the 16 PF. Users of barbiturates and sedative-hypnotics were most severely maladjusted, followed by users of opiates, users of cocaine, users of amphetamine and its congeners, and nonusers. Differences also appeared between combined users of stimulants, combined users of depressants, and nonusers, as well as between all drug users (as a group) and nonusers. This research is offered as a methodological paradigm for evaluating future studies. It illustrates how the representative case method may be expanded to permit comparisons among groups.

[Neuropsychological aspects of schizophrenic mental deterioration].

The authors have administered a test of intelligence (WAIS) and a test of attention (Color Naming) to a group of patients affected by chronic schizophrenic impairment. The scores give shape to a picture of mental deterioration, especially characterized by a decrease of attentive power. This results validates the possibility of a neuropsychological approach to the etiopatogenesis of schizophrenia and supports the hypothesis that an impairment of mental synthesis power may explain both clinical and psychometric features of the disease.
