Perceptual learning solely induced by feedback

Perceptual learning solely induced by feedback

Although feedback is considered to be an important factor in perceptual learning (PL), its role is normally considered limited to facilitation, rather than direct inducement, of PL. Recent studies, however, have suggested feedback to be more actively involved in the inducement of PL. The current study demonstrates an even more significant role for feedback in PL: feedback can evoke PL of a feat...

Boosting perceptual learning by fake feedback

How does the brain control its sensory plasticity using performance feedback? We examined this question using various types of fake feedback in perceptual learning paradigm. We demonstrated that fake feedback indicating a larger performance improvement facilitated learning compared with genuine feedback. Variance of the fake feedback modulated learning as well, suggesting that feedback uncertai...

Modeling trial by trial and block feedback in perceptual learning

Feedback has been shown to play a complex role in visual perceptual learning. It is necessary for performance improvement in some conditions while not others. Different forms of feedback, such as trial-by-trial feedback or block feedback, may both facilitate learning, but with different mechanisms. False feedback can abolish learning. We account for all these results with the Augmented Hebbian ...

Perceptual Learning from Cross-modal Feedback

Effects of Feedback on Perceptual Learning

This study investigated how feedback can be used to improve the perception of speech from visual-only displays. Participants saw English words spoken in two different, visual-only displays: full-face displays, in which a speaker’s whole face is seen under normal lighting conditions, and point-light displays, which preserve only some of the dynamic information that is visible in speech. The part...
