Long-term memory of haptic, visual, and cross-modality information was investigated. In Experiment 1, subjects briefly explored 40 commonplace objects visually or haptically and then received a recognition test with categorically similar foils in the same or the alternative modality both immediately and after 1 week. Recognition was best for visual input and test, with haptic memory still apparent after a week's delay. Recognition was poorest in the cross-modality conditions, with performance on the haptic-visual and visual-haptic cross-modal conditions being nearly identical. Visual and haptic information decayed at similar rates across a week delay. In Experiment 2, subjects simultaneously viewed and handled the same objects, and transfer was tested in a successive cue-modality paradigm. Performance with the visual modality again exceeded that with the haptic modality. Furthermore, initial errors on the haptic test were often corrected when followed by the visual presentation, both immediately and after 1 week. However, visual test errors were corrected by haptic cuing on the immediate test only. These results are discussed in terms of shared information between the haptic and visual modalities, and the ease of transfer between these modalities immediately and after a substantial delay.
