The relationship between intelligence and verbal and spatial memory.

Administered the Logical Memory Test (LM) and the Rey-Osterreith Test (RO), which have been assumed to pertain to verbal and spatial cognitive functioning, to 150 Ss referred for neuropsychological screening. Ss also were administered the short version of the WAIS, plus Digit Span. It was found that LM did relate more to verbal IQ than to spatial IQ and vice-versa for RO. It was not clear exactly what aspect of cognitive functioning Digit Span was tapping. The clinical implications of the study are that LM scores must be viewed in the light of verbal IQ level, and RO scores interpreted in relation to both spatial IQ and age. Data are presented that can be used for the statistical interpretation of an individual case test scores.
