Abstract: | Masking of the perception of an electrical test stimulus by a mechanical shock was studied in six Ss. Forward and backward masking were observed in all Ss, the former being of longer duration. Duration of the masking effects is inversely related to the intensity of the test stimulus. Masking effects may be preceded and followed by perceptual facilitation. The masking effects may be responsible for the alterations in the perception of a somaesthetic stimulus before and during movement of the stimulated area. |
