Abstract:
Real world scene perception can often involve more than one sensory modality. Here we
investigated the visual, haptic and crossmodal recognition of scenes of familiar objects. In three experiments participants first learned a scene of objects arranged in random positions on a platform. After learning, the experimenter swapped the position of two objects in the scene and the task for the participant was to identify the two swapped objects. In Experiment 1, we found a cost in scene recognition performance when there was a change in sensory modality and scene orientation between learning and test.
The cost in crossmodal performance was not due to the participants verbally encoding the objects
(Experiment 2) or by differences between serial and parallel encoding of the objects during haptic and
visual learning respectively (Experiment 3). Instead, our findings suggest that differences between visual and haptic representations of space may affect the recognition of scenes of objects across these modalities.
