The Role of Spatial and Modality Cues on Visual and Haptic Memory

This study investigates the ability to remember a sequence of stimuli in two basic conditions: haptic and visual. Participants rely on a combination of modal and/or spatial information to perform a memory task. For this purpose, an experimental setup was developed based on the “Simon Says” memory game. Individuals receive a series of sensory stimuli and need to remember the sequence and repeat it. The stimuli in visual conditions are colored or white lights, and the stimuli in haptic conditions are vibration, hot, cold, and skin stretch. Results demonstrate that participants retained longer sequences in spatial conditions compared to the modal conditions. It is also demonstrated that participants performed better in visual conditions compared to haptic conditions. Participants were able to retain more complex spatial patterns and remember them faster in visual conditions compared to haptic conditions. A spatial difficulty ranking system was developed, indicating how easily each spatial pattern can be retained visually and haptically.
