Constraints on Haptic Short-Term Memory
This study examines to what extent limitations in short-term memory capacity in the haptic modality depends on (1) the narrowness of the effective field of view combined with a sequential processing of information, and/or (2) the format in which spatial configurations are represented internally. A total of 64 participants carried out memory span tasks in four different conditions: haptic, visual, visual with a limited field of view, and haptic with visual cues. Results provide support for both hypotheses. Differences in haptic and visual short-term memory disappeared when the visual processing of information occurred within a limited field and when the haptic processing of information was aided by visual cues.
