An Evaluation of Modality Preference Using a “Morse Code” Recall Task

Abstract

Advocates of modality preference posit that individuals have a dominant sense and that when new material is presented in this preferred modality, learning is enhanced. Despite the widespread belief in this position, there is little supporting evidence. In the present study, the authors implemented a Morse code–like recall task to examine whether visual and auditory recall is moderated by modality preference. When the perceptual discriminability of visual and auditory stimuli was controlled for, there was no significant relation between (a) modality preference and (b) visual and auditory recall. The nature of the task did however effect performance. When a temporal discrimination between stimuli was required, recall for auditory stimuli was superior to recall of visual stimuli. In contrast, when the task involved a spatial discrimination, the opposite effect was observed. It is not surprising that in each recall task, sequences with a discernible pattern were recalled more accurately than were sequences that lacked any obvious pattern. The authors concluded that the ability to recall simple material is determined more by the type of stimulus than by the preferences of the individual.
