The enhancement of mental imagery through the utilization of a digital soundfield processor
The present investigation compared the effects of sound effects presented by a Yamaha Digital Sound Field Processor (DSP-1), sound effects presented by a two-speaker stereo system, and spoken descriptions of scenarios on four measures thought to be related to an individual's ability to imagine visual scenes. The measures were: image clarity, ease of evocation of an image, ease of maintenance of an image, and the number of adjectives used to describe the auditory stimuli (sound effects and a spoken description of scenarios). Forty-eight undergraduate psychology students were randomly assigned in equal numbers to each of three experimental conditions: 1) a group using the DSP-1, 2) a group using a stereo system, and 3) a group hearing a spoken description of scenarios. Using four separate ANOVAs, the only statistically significant findings were that subjects who listened to spoken descriptions of scenarios responded with a significantly greater number of adjectives than did subjects in the other experimental conditions. The difficulties involved in investigating private, subjective experiences such as visual images are discussed .
