The effect of cognitive load on social categorization in the category confusion paradigm

The category confusion paradigm (Taylor, Fiske, Etcoff & Ruderman, 1978) wa s used to examine the relationship between cognitive load and the extent of social categorization. The original prediction made by Taylor et al. (1978 ; Experiment 2) and inferences from the cognitive miser model suggest that categorization should increase or be unaffected by cognitive fond. In contr ast, it is argued that social categorization can be an effortful and resour ce-consuming process, especially, where the representation of multiple stim uli are concerned. This leads to the prediction that social categorization should decrease with load-assuming there is enough load to produce recall e r rows in the first place. We obtained results consistent with this analysi s in paradigms which manipulated load by means of set-size (Study I) and pr ocessing pace (Study 2). Copyright (C) 1999 John Wiley & Sons, Ltd.
