Abstract: | An experiment was carried out in which Ss had to decide whether or not a target word was a member of a prespecified semantic category. Poorly representative, or low conjoint frequency (LCF) exemplars were accepted less rapidly than representative, or high conjoint frequency (HCF) exemplars. This effect was considerably enhanced by requiring an incompatible response in which the Ss were asked to say ‘No’ when the target was a member of the category. The results show that the category membership judgement is a natural affirmative, and that the semantic distance effect of conjoint frequency has a magnitude dependent upon the processing demands of the task in which it is measured. The results are discussed in relation to theories of the mechanisms of category membership judgements. It is suggested that the influence of compatibility may be in load sharing between activation of a response rule and the judgement task per se. |
