One hundred fifty-nine male African adults from the Belgian Congo were given a paper-and-pencil perceptual task devised by A. Rey and consisting of drawing lines between randomly arranged black dots so as to isolate simple geometrical figures. A practice task, where the perceptual difficulty was reduced by printing in different colors the dots corresponding to the different figures, was always given first. Both tasks were given without time-limit. Scores were number of correct patterns on the black test, and time taken to complete each of the two tasks. Both time scores were combined by Hotelling's principal components method. Two independent variables were obtained, one of which (J) expresses the general tendency to be slow on both tasks and the other the tendency to be slower on the (difficult) black patterns than on the (easier) color ones. The relationship of these components to accuracy on the black patterns was determined. Africans were compared on both time components with Belgian Ss at the same accuracy level. (It was necessary to use children because European adults are too accurate en this test.) It appears that, for the same degree of accuracy, Africans are always slower on J, but no difference is apparent on B. It is concluded that, as far as these tasks are considered, the slowness of the Africans--defined by comparison with Europeans of the same level of accuracy--is not related to task difficulty. This finding is more easily explained by a general lack of interest in speed performance than by a slower operation of mental functions. [ABSTRACT FROM AUTHOR]
