Mechanisms of perceptual learning

See Fig.2, Perceptual Template Model (PTM) 

:

The PTM characterizes human performance in perceptual tasks in terms of a signal processing filter or template, an optional transducer nonlinearity, an internal additive noise source, and an internal multiplicative noise source. The stimulus consists of a signal plus external noise. The internal additive noise source is independent of the contrast of the stimulus; the internal multiplicative noise source increases directly with the contrast of the stimulus (signal plus external noise).

Fig.3, Three mechanisms of perceptual learning.

(1) Practice that turns up the gain on the stimulus, corresponding to stimulus enhancement. 

(2)  Practice that affects the amount of external noise processed through the perceptual template by narrowing the filter tuning, corresponding to external noise exclusion. 

(3) Practice that reduces the gain on multiplicative internal noise, or internal multiplicative noise reduction.
