The present study examined the effects of cohesiveness of pictorial materials on long-term memory of descriptive information with three pictorial materials : whole picture (whose parts are integrated and make a meaningful whole), nonsense-whole picture (whose parts are integrated but not make a meaningful whole), and part picture (whose parts are not integrated nor make a meaningful whole). As retention interval was prolonged from 1 week to 4 months the positive effects of cohesiveness of pictorial materials on memory of descriptive information became conspicuous. With the results some tentative interpretations of the effects of cohesiveness of pictorial materials were discussed.
