Pictorial enhancement of text memory: limitations imposed by picture type and comprehension skill

We examined the kinds of information in a prose passage that is better remembered when depictive illustrations are embedded in the passage than when the passage contains no illustrations. Experiment 1 showed that (1) pictures depicting details effectively increased recall of those details and (2) pictures depicting relationships effectively increased recall of that relational information (relative to a no-picture control condition). In Experiment 2, comprehension skill was found to modulate the general effects obtained in Experiment 1. Detail pictures enhanced the recall of targeted details for all skill levels. Relational pictures enhanced recall of pictured relational information for highly skilled and moderately skilled comprehenders, but not for less skilled comprehenders. Because there were no recall differences across the different skill levels in the no-picture control condition, it is suggested that pictures may serve to enable processing in which readers would not necessarily engage under ordinary circumstances. Pictures, however, did not appear to compensate for limitations reflected in lower scores on a standardized test of reading comprehension.
