Theory 55/Precision & Information/Perceptual learning
Learning Follows Precision
The claim
The rate of perceptual learning is set by the ratio of practice precision to task noise, so practice with feedback that is more precise than the task teaches little.
01Mechanism
Learning requires an error signal above the noise; feedback finer than the task's variability provides no gradient.
02Prediction
Learning rate should track the ratio.
03Refutation
Learning tracking practice amount would remove precision.
