Perceptual encoding in comparative judgments of race.

Ss made comparative judgments along the black-white racial dimension using opposite response sets ("Which is blacker?" or "Which is whiter?"). Three classes of pictures were used: B (black),W (white), and M (racially mixed). I or the BM judgments. "Which is whiter?" took significantly longer. The MW and BW judgments showed no difference between response instructions. Analysis of the stimuli showed that skin tone was not the primary perceptual attribute used in racial encoding. The observation of a funnel effect in the judgment latencies is shown to be consistent with other research demonstrating the effect of response set in comparative judgments Further. the results support sociological observations about the cultural use of the linguistic labels "black" and "white"
