Tactile interactions in the path of tactile apparent motion

Perceptual completion is a fundamental perceptual function serving to maintain robust perception against noise. For example, we can perceive vivid experience of motion even for the discrete inputs across time and space (apparent motion: AM). In vision, stimuli irrelevant AM are suppressed smooth along trajectory where no physical applied. We investigated whether such masking induced by dynamic general sensory modalities focusing on touch. Participants tried detect vibro-tactile target stimulus presented two other tactile forearm. control condition, inducing were applied simultaneously, resulting in percept. Tactile detection was impaired with AM. Our findings support notion that mechanism rather than specific effect.
