Attitudes toward people with disabilities should be measured because prejudice toward and discrimination against them still exist.  The present paper reviews implicit measures of attitudes toward people with disabilities, in contrast to other research that used explicit measures such as questionnaires.  Implicit measures tend not to be affected by social desirability, so that they are able to assess automatic, non-conscious, and nonverbal attitudes.  The main categories of implicit attitude measures are projective techniques, physiological and neurological methods, and measures of response latency.  Many of the studies that used these measures revealed implicit negative attitudes toward people with disabilities.  The discussion concerns the relation between implicit and explicit attitudes, the merit of using implicit measures, and issues to be addressed in the future.
