The accessibility of the term “contempt” and the meaning of the unilateral lip curl

Four studies are reported investigating the conditions under which various proposed facial expressions of contempt are labelled “contempt”. Only under forced-choice conditions are any of these expressions labelled “contempt” above chance; free responses are at or below chance. Contrary to predictions from Rosenberg and Ekman's (1995) explanation of poor free-response performance, participants demonstrating the best understanding of “contempt”, and those primed by prior tasks to have the concept readily accessible did not do better than other subjects. Using the forced-choice paradigm, supposedly neutral expressions were labelled “contempt” by 70% of respondents. It is concluded that poor performance in free-response studies is not due to inaccessibility or unfamiliarity of “contempt”, that the unilateral lip curl included in the JACFEE set of expressions of basic emotions (Matsumoto & Ekman, 1988) is not decoded as contempt, and that good performance in forced-choice studies results from artifacts of the method.     

Problems with Principle P

Abstract: In Psychosemantics Fodor presents three arguments for preferring the language of thought over mere intentional realism - arguments for the conclusion that intentional causes of behavior have constituent structure. The first of these, relying on the methodological 'Principle P', is considered in detail here and is found wanting. This principle does not prefer the language of thought to those very connectionist systems which Fodor criticizes; and it rests on dubious theoretical and empirical assumptions.
