Sequential Processes in Image Generation: An Objective Measure. Technical Report #6.
Kosslyn, Stephen M.; And Others
This paper investigates the processes by which visual mental images--the precept-like short-term memory representations--are created from information stored in long-term memory. It also presents a new method for studying image generation. Three experiments were conducted using college students as subjects. In the first experiment, a Podgorny and Shephard paradigm was adapted to study image generation. In the second experiment, regression analyses were performed on response times in a scanning instruction and no-scanning instruction condition. Experiment three was designed to investigate whether scanning plays a functional role in image generation. Results indicated that images of upper case letters are formed segment by segment, in roughly the order in which most people draw the letters. Results were shown not to be an artifact of how people scan images once they are formed, and could not have been due to experimenter-expectancy effects. Results also indicated that subjective estimates of mental image generation time are quite close to those obtained using objective measures. (Author/LMO)
