Research paper thumbnail of Changes In Spatial Position of Hands Modify Tactile Extinction but Not Disownership of Contralesional Hand In Two Right Brain-Damaged Patients

These symptoms typically occur with personal or extrapersonal neglect and extinction of left-sided stimuli, suggesting that all these different symptoms may be linked to the same neural substrate. In the present research, we tested two right brain-damaged (RBD) patients to find out whether changing the position of the hands in space influences tactile extinction and denial of ownership to the same extent. Results showed that manipulation of the spatial position of the hands reduces tactile extinction but leaves denial of ownership of the left hand unaffected. Such a dissociation suggests that delusional misperceptions may be independent from somatic neglect and that representation of hands in space and attribution of ownership are dynamically mapped in at least partly separate neural substrates.

The stimuli were presented from either the same or different locations in order to explore the potential effect of redundant spatial information on audiotactile temporal perception. In Experiment 1, the auditory and tactile stimuli had to be separated by nearly 80 ms for inexperienced participants to be able to judge their temporal order accurately (i.e., for the just noticeable difference (JND) to be achieved), no matter whether the stimuli were presented from the same or different spatial positions. More experienced psychophysical observers (Experiment 2) also failed to show any effect of relative spatial position on audiotactile TOJ performance, despite having much lower JNDs (40 ms) overall. A similar pattern of results was found in Experiment 3 when silent electrocutaneous stimulation was used rather than vibrotactile stimulation. Thus, relative spatial position seems to be a less important factor in determining performance for audiotactile TOJ than for other modality pairings (e.g., audiovisual and visuotactile).

Pairs of auditory and tactile stimuli were presented from the left and/or right of participants at varying stimulus onset asynchronies (SOAs) using the method of constant stimuli. The participants had to make unspeeded TOJs regarding which sensory modality had been presented first on each trial. Systematic differences between the participants emerged: While the performance of the sighted participants was unaffected by whether the two stimuli were presented from the same or different positions (replicating the results of several recent studies), the blind participants (regardless of the age of onset of blindness) were significantly more accurate when the auditory and tactile stimuli were presented from different positions rather than from the same position. These results provide the first empirical evidence to suggest a spatial modulation of audiotactile interactions in a temporal task performed by visually impaired humans. The fact that the performance of the blind participants was modulated by the relative spatial position of the stimuli is consistent with data showing that visual deprivation results in an improved ability to process spatial cues within the residual tactile and auditory modalities. These results support the hypothesis that the absence of visual cues results in the emergence of more pronounced audiotactile spatial interactions.
