THE EFFECTS OF CONCURRENT PICTURE PRESENTATIONS ON RETELLING OF ORALLY PRESENTED STORIES BY ADULTS WITH APHASIA

This study investigated whether measures of verbal productivity, verba l disruption, information content, grammatical complexity, and grammat ical well formedness would vary as a function of experimental conditio ns in which the presence of pictured stimuli was manipulated during th e oral presentation and retelling of stories. Fifteen adults with apha sia retold stories under three experimental conditions: (i) concurrent presentation of oral and pictured versions of stories followed by a p icture-supported retell, (ii) concurrent presentation of oral and pict ured versions of stories followed by a 'free' retell, and (iii) orally presented stories followed by a free retell. Group analyses revealed no significant differences across experimental conditions for any of t he dependent measures. Analyses of individual subjects' data revealed clinically important differences for several measures of information c ontent, with individual subjects responding differently to the experim ental conditions.
