Simultaneous Stimulus Preexposure Enhances Human Tactile Perceptual Learning
Rodríguez, Gabriel; Angulo, Rocío

An experiment with human participants established a novel procedure to assess perceptual learning with tactile stimuli. Participants received unsupervised exposure to two sandpaper surfaces differing in roughness (A and B). The ability of the participants to discriminate between the stimuli was subsequently assessed on a same/different test. It was found that prior exposure to the stimuli led to more accurate judgements on the different-trials. Furthermore, simultaneous exposure to the stimuli enhanced this accuracy more than sequential exposure (A, B, A, B…). These findings extend recent results from visual studies to the tactile modality, confirming that simultaneous exposure produces a marked perceptual learning effect.
