The Relationship

AbstractProcessing speed is the most impaired neuropsychological domain in schizophrenia and a robust predictor of functional outcome. Determining the specific cognitive operations underlying processing speed dysfunction and identifying their neural correlates may assist in developing pro-cognitive interventions. Response selection, the process of mapping stimuli onto motor responses, correlates with neuropsychological tests of processing speed and may contribute to processing speed impairment in schizophrenia. This study investigated the relationship between behavioral and neural measures of response selection, and a neuropsychological index of processing speed in schizophrenia. Twenty-six patients with schizophrenia and 21 healthy subjects underwent functional magnetic resonance imaging scanning during performance of two- and four-choice reaction time (RT) tasks and completed the Wechsler Adult Intelligence Scale-III (WAIS) Processing Speed Index (PSI). Response selection, defined as RT slowing between two- and four-choice RT, was impaired in schizophrenia and correlated with psychometric processing speed. Greater activation of the dorsolateral prefrontal cortex (PFC) was observed in schizophrenia and correlated with poorer WAIS PSI scores. Deficient response selection and abnormal recruitment of the dorsolateral PFC during response selection contribute to processing speed impairment in schizophrenia. Interventions that improve response selection and normalize dorsolateral PFC function may improve processing speed in schizophrenia. (JINS, 2013, 19, 1–10)

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.
