National Adult Reading Test

To determine whether the National Adult Reading Test (NART) would provide a valid estimate of premorbid intelligence in schizophrenia, two schizophrenic samples were recruited, one consisting of 35 patients resident in long-stay wards, the other of 29 patients normally resident in the community. Schizophrenic patients were individually matched for age, sex, and education with a healthy, normal subject. Both schizophrenic samples scored significantly lower on the Wechsler Adult Intelligence Scale (WAIS) than their respective control groups. NART-estimated IQ did not differ significantly between the community-resident schizophrenics and their controls, suggesting that the NART provides a valid means of estimating premorbid intelligence in such a population. NART-estimated IQ was significantly lower in the long-stay sample than in their controls. Although low NART scores in this latter sample could be a valid reflection of low premorbid IQ, the alternative explanation that NART performance was impaired by onset of the disease cannot be ruled out.

And Control

The aim of present research was to investigate the performance of visual perceptual tasks with varying the degree of uncertainty and levels of regulation prescribed by vague, verbal and non-verbal instructions. The modified Witkin test and Wechsler Adult Intelligence Scale, a revised form (WAIS-R) were used. 36 anankastic personality disorder patients (mean age-31,9±9,8 years), 38 schizophrenic patients (pseudoneurotic type, mean age 30,8±8,7 years) and 100 healthy controls (mean age 27,5±8,5 years) were enrolled to the study. It was established that the effectiveness of the performance of visual perceptive tasks in conditions of vague instruction did not differ among the subjects of all three groups. The introduction of additional verbal instruction increased the performance of healthy subjects and patients with anankastic personality disorder, in contrast to patients with schizophrenia. In conditions of nonverbal instruction, the effectiveness of performing was reduced in clinical and control groups, but the parameters of healthy subjects were significantly higher (р≤0,05). It was found in schizophrenia an increase in the number and strength of the correlation between the indices of the performance of visual perceptual tasks and the non-verbal parameters of Wechsler Adult Intelligence Scale.

Wechsler Adult Intelligence

Diese Studie untersucht die Zusammenhänge von Intelligenz- und Gedächtnisleistungen in der Wechsler Adult Intelligence Scale-IV und der Wechsler Memory Scale-IV unter Berücksichtigung des Geschlechts (N = 137 Gesunde, 63 w/74 m). Ein Vorteil der weiblichen Testpersonen im verbalen episodischen Gedächtnis sowie in einzelnen Aufgaben zur Verarbeitungsgeschwindigkeit konnte beobachtet werden. Die männlichen Testpersonen schnitten in den Untertests Allgemeines Wissen und Visuelle Puzzles besser ab. Wie gut Gedächtnisleistungen Intelligenzleistungen erklären beziehungsweise vorhersagen, ist aufgrund unserer Ergebnisse nicht nur abhängig von den Aufgaben, sondern auch vom Geschlecht.

Deutschsprachige Version

Im vorliegenden Beitrag wird der Datensatz (N = 1664), aus dem auch die Normstichprobe für die deutschsprachige Version der Wechsler Adult Intelligence Scale – Fourth Edition (WAIS-IV) gezogen wurde, nach altersabhängigen Veränderungen kognitiver Fähigkeiten analysiert. Die niedrigsten Rohwertmittelwerte werden in der ältesten Altersgruppe erreicht, die Leistungsspitzen finden sich überwiegend im Altersbereich zwischen 20 und 29 Jahren. In den Untertests der Indizes Wahrnehmungsgebundenes Logisches Denken und Verarbeitungsgeschwindigkeit kommt es zu einer bedeutsamen Leistungsabnahme mit zunehmendem Alter: In der ältesten Altersgruppe werden nur noch zwischen 50 und 60 % der Rohwertmittelwerte der leistungsstärksten Altersgruppe erreicht. Gleichzeitig nimmt die Heterogenität in der Rohwertverteilung zu. Für die Indizes Sprachverständnis und Arbeitsgedächtnis fallen beide Effekte deutlich niedriger aus.

Intelligence Scores

The present study examined associations between Wechsler Adult Intelligence Scale–Revised (WAIS–R) scores and the five-factor model of personality, as measured by the Revised NEO Personality Inventory. Both tests were administered to a nonclinical sample of 100 Italian subjects 75 years and older. Analysis showed that the NEO-PI–R Openness to Experience domain was a weak but the best predictor of the three WAIS–R intelligence scores (Total, Verbal, and Performance). Were such a relationship confirmed by further investigations, Openness could be interpreted as a factor which might mitigate intellectual impoverishment which accompanies the normal aging process.
