Context effects of facial appearance on attitudes toward mentally handicapped persons

The influence of facial appearance on social attitudes was examined by exposing participants to the faces of three target persons with or without deviant facial features, posing happy, angry or sad facial expressions, or a mixture of these expressions. When they displayed negative emotional expressions, facially deviant targets were judged more negatively than non-deviant targets. Irrespective of emotional expression and level of personal experience, participants expressed more negative attitudes toward mentally handicapped persons in general after exposure to deviant faces than after exposure to non-deviant faces, or in the absence of exposure. However, correlational analyses suggested that only at low levels of personal experience were attitudes influenced by previously formed impressions of deviant exemplars. Results are discussed in terms of the motivational relevance of physical features in stigmatization, and context and exemplar effects in stereotyping and attitude measurement. Practical implications are also discussed.
