Abstract: | Three experiments were conducted to determine the role of imagery in aiding memory for visual information and to compare its effectiveness relative to direct perception. Subjects engaged in orienting tasks in which they had to decide whether the second of two sequentially presented meaningless patterns was a part of the first. They later received unexpected recognition tests for the original drawings. Increasing the interval between patterns by adding an extra post-stimulus period for imaginal processing improved later recognition scores. Experiments comparing continued perception with an equal blank interval suggested that periods of direct perception and of imagery are about equally effective in promoting memory. The results are discussed in the frame work of Craik and Lockhart (1972) with regard to type I and type II processing, and in the light of Neisser's (1967) view on imagery and perception. |
