Does mental rotation ability depend on sensory-specific experience?
Résumé
No study has investigated the link between vision and touch with respect to spatial abilities using a within-subjects design. With this design, we compared participants’ tactile and visual mental rotation abilities, as measured by the Mental Rotations Test (Vandenberg & Kuse, 1978). Participants in four groups completed two consecutive sessions under no-switch (visual-visual or tactile-tactile) or switch conditions (visual-tactile or tactile-visual) to determine whether mental rotation abilities assessed in Session 2 depend on previous sensory-specific experiences (Session 1). Analysis of response accuracy revealed that all groups improved their performance in Session 2. Analysis of response time showed an improvement in visual and tactile performance during Session 2 for participants who first performed the task with the same modality. No effect of task repetition appeared for participants who performed in two different sensory conditions. These results reveal that mental rotation ability partly depends on sensory-specific conditions and that ability developed in a sensory-specific condition does not necessarily transfer to another sensory condition.
