Perceptual Learning: Complete Transfer across Retinal Locations
نویسنده
چکیده
A newly developed 'double training' technique demonstrates that practice-dependent improvement in the discrimination of basic visual features will transfer to a location that has been trained with a different discrimination.

Complete Transfer of Perceptual Learning across Retinal Locations Enabled by Double Training
Practice improves discrimination of many basic visual features, such as contrast, orientation, and positional offset. Perceptual learning of many of these tasks is found to be retinal location specific, in that learning transfers little to an untrained retinal location. In most perceptual learning models, this location specificity is interpreted as a pointer to a retinotopic early visual cortic...
متن کاملVernier perceptual learning transfers to completely untrained retinal locations after double training: a "piggybacking" effect.
Perceptual learning, a process in which training improves visual discrimination, is often specific to the trained retinal location, and this location specificity is frequently regarded as an indication of neural plasticity in the retinotopic visual cortex. However, our previous studies have shown that "double training" enables location-specific perceptual learning, such as Vernier learning, to ...
متن کاملDecoupling location specificity from perceptual learning of orientation discrimination
Perceptual learning of orientation discrimination is reported to be precisely specific to the trained retinal location. This specificity is often taken as evidence for localizing the site of orientation learning to retinotopic cortical areas V1/V2. However, the extant physiological evidence for training improved orientation turning in V1/V2 neurons is controversial and weak. Here we demonstrate...
متن کاملExogenous attention facilitates location transfer of perceptual learning.
Perceptual skills can be improved through practice on a perceptual task, even in adulthood. Visual perceptual learning is known to be mostly specific to the trained retinal location, which is considered as evidence of neural plasticity in retinotopic early visual cortex. Recent findings demonstrate that transfer of learning to untrained locations can occur under some specific training procedure...
متن کاملERP P1-N1 changes associated with Vernier perceptual learning and its location specificity and transfer.
Our recent studies demonstrate that perceptual learning can transfer completely to untrained retinal locations upon proper training procedures, which suggests perceptual learning being a high-level learning process occurring beyond the retinotopic visual areas. We propose that whether learning is location specific depends on the functional connections between high-level learning and the sensory...
