Communication Accuracy in Lower- and middle-SES children as a function of task abstraction

The Communication encoding performance of lower-SES black, lower-SES white, and middle-SES white children was evaluated when the same familiar stimuli for eliciting communication were presented at three different levels of abstraction. No differences were found between social-class groups. Performance did not differ as a function of level of abstraction. The social group X level of abstraction interaction was not significant. Thus the level of abstraction of the stimuli does not impede the communication encoding performance of lower-SES children. Previous findings of social-class differences in communication accuracy may be an artifact of stimuli that are not equally familiar to all groups.
