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.

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)

Pearson Correlations

The Stanford-Binet Intelligence Scale: Fourth Edition and the Wechsler Adult Intelligence Scale—Revised were given to 32 general psychology students (16 men, 16 women). All 15 Pearson correlations between the composite and area scores of Binet IV with WAIS—R IQs were statistically significant. Of 5 correlations for subtest pairs of the two tests, 4 (.59 to .86) were statistically significant. Binet IV may be a viable alternative or retest instrument for WAIS—R for use with young adults.
