Abstract : Two groups of subjects were tested in a forced-choice recognition test for memory of 20 random shapes having two levels of complexity and two levels of association value. One group of 23 subjects viewed each shape for 0.25 sec., and the other group of 23 subjects viewed each shape for 0.50 sec. Fewer errors of recognition were made for shapes of high association value than for shapes of low association value while the effects of complexity and exposure duration were statistically insignificant. Consideration of the characteristics of the distractor shapes paired with the observed shapes during the forced-choice recognition test suggested that they may also have influenced recognition accuracy.
