The influence of context on the auditory comprehension of paragraphs by aphasic subjects.
Subjects were exposed to two sets of paragraphs that probed their auditory comprehension abilities under various prestimulation conditions. In Experiment 1, aphasic and control subjects listened to four paragraphs. Each paragraph was preceded by a control condition (no antecedent) or one of the following contextual antecedents: picture, verbal, or picture and verbal combined. Prestimulation with a picture alone was detrimental, but prestimulation with a picture used in combination with a verbal context appeared to be of value. In Experiment 2, subjects heard four paragraphs that were less cohesive than those in Experiment 1. Only verbal and control conditions were contrasted. The provision of prior verbal contexts facilitated the auditory comprehension of the paragraphs.
