Embedded Figures Test compared with clinical tests of abstraction and memory in intellectual impairment

Results on a batter of memory and concept formation tests were compared with performance on the Embedded Figures Test (EFT) and the Visual Gestalts Test for 50 psychiatric patients with intellectual impairment (35 males and 15 females, aged 25–69 years). The EFT only correlated with the concept formation tests and the Visual Gestalts Test. Furthermore, an interrelationship between the EFT results and the degree of intellectual impairment was found. Also, the patients' performance on the EFT was significantly impairment was found. Also, the patients' performance on the EFT was significantly poorer than that of normal individuals. Thus it was concluded that the EFT should be considered as a visuo-spatial test of abstraction, sensitive to intellectual impairment.
