Developmental differences in attitudes toward physically disabled individuals were measured with an instrument requiring spontaneous responding and utilizing a systematic scoring taxonomy. Additionally, relations between attitudes, moral judgment development, and belief in a just world were explored. Forty high school freshmen and 40 seniors as well as 40 undergraduate college students read brief descriptions of individuals with a physical or sensory disability, rated each hypothetical individual on a series of items, and provided reasons for each rating. When reasons were scored for presence of devaluing responses, the three age groups did not differ in amount of devaluing. Within age groups, moral judgment scores (Defining Issues Test), scores on the Just World Scale, and scores on the Attitudes toward Disabled Persons Scale accounted for as much as 33% of the total variation in devaluing responses. The main effect for narrative (handicapping condition) was highly significant. (Author/CL)
