The report presents the findings of research that compared high and low aptitude subjects on two form discrimination tasks that required both intramodal and intermodal functioning. In the first experiment, 20 high and 20 low aptitude Army trainees were required to make a simultaneous discrimination of nonsense forms, using vision and touch. The second experiment, with 30 high and 30 low aptitude men, introduced a delay period between the presentation of the standard and comparison stimuli. Analysis showed the relation of high aptitude to higher-order processing or learning strategies. Author Modified Abstract
