The Role of Visual Mental Imagery in the Speed-Accuracy Tradeoff: A Preliminary Investigation.
Hodes, Carol L.
This study investigates the relationship between speed of recognition and accuracy of the responses when visual mental imagery is controlled through imagery instructions. The procedure was to compare the achievement of learners where the independent variable was imagery instructions. The subjects were two 20-person groups of undergraduates from a small liberal arts college. The experimental treatment consisted of the same materials for each group--a 5-page, 1200-word instructional booklet about a graphical user interface (GUI) computer operating system. The sessions were administered separately to keep knowledge of the independent variable from the control group. Subjects who were given imagery instructions prior to receiving the stimulus material required significantly more time to learn the material. The instructed subjects also had significantly faster retrieval time on a recognition posttest. Thus, the relationship between learning time and retrieval time for imaged information is inverse. The posttest scores of the imagery instructed subjects were not significantly higher than the uninstructed subjects. The two groups also had similar perceptions of their use of mental imagery. Visual mental imagery could be a technique which will reduce the speed-accuracy tradeoff when accurate responses must be made quickly. (Contains 23 references.) (Author/JLB)
