Block Design Test Performance as a Function of Race and Block Color.
Mitchell, Nancy B.; Pollack, Robert H.
The purpose of this study was to see if a relationship between color sensitivity and skin pigmentation would affect performance on the WISC block design subtest when both the standard red/white design and the blue/yellow design were used. It was hypothesized that the white children would perform better overall because black children have been found to be poor in spatial skills and because the greater fundus pigmentation of the black children should make them less sensitive to blue, based on findings that greater fundus pigmentation creates less sensitivity to the short wave end of the spectrum. Eighty children, 40 white and 40 black, were given the block design task in natural lighting on a cloudy day. Half of each racial group were given the red/white design and half the blue/yellow design. Results were significant in the predicted direction. White children were not affected by the block design color, while the scores for black children were significantly different on the blue/yellow design. Scores for the two races were not significantly different for the red/white design. Part of the experiment has been replicated under good lighting conditions with black children. Data have not been completely analyzed, but it appears that the performance difference between red/white and blue/yellow is not significant. (KM)
