Topic: 2AFC task

Training subjects to discriminate fine details of stimuli can improve perceptual capabilities, a phenomenon known as perceptual learning (PL). Experiments have discovered intriguing psychophysical findings despite the simple stimuli (e.g., Gabor patches) and training procedures (e.g., 2AFC task) involved. Finding explanations for these learning effects could shed light on sensory plasticity in adulthood and constraints in sensory processing. A profound feature of (visual) PL is its slow learning speed, which can take days of training and hundreds or thousands of trials for the performance to s
