In the early 1960s Gibson and Caviness performed various experiments on visual and haptic shape discrimination – experiments whose data and detailed results were, unfortunately, never published. Recently, we have acquired and duplicated the original Gibson ‘feelie’ stimuli using 3D scanning and printing technologies. In these experiments, we examine the visual and haptic perception of the feelies along with the well-studied, naturalistic stimuli of bell peppers.
For these classes of stimuli there is apparently no effect of modality on performance, but the type of object matters. This is likely due to the relative complexities of the stimuli which is consistent with previous findings.
To perform experiments on further shapes.
