What is new in perceptual learning?

Michael Herzog, Lukasz Grzeczkowski, Aline Françoise Cretenoud

What is new in perceptual learning? In the early days of research, specificity was the hallmark of perceptual learning; that is, improvements following training were limited to the trained stimulus features. For example, training with a stimulus improves p ...

Hyper-specificity of perceptual learning

Lukasz Grzeczkowski

Perceptual learning is the ability to improve perception through practice. Perceptual learning is usually specific for the task and the stimulus features trained with. For example, training orientation discrimination with vertically oriented stimuli does n ...

Does sensitivity in binary choice tasks depend on response modality?

Michael Herzog, Lukasz Grzeczkowski, Izabela Szumska

In most models of vision, a stimulus is processed in a series of dedicated visual areas, leading to categorization of this stimulus, and possible decision, which subsequently may be mapped onto a motor-response. In these models, stimulus processing is thou ...

About common factors in vision

Michael Herzog, Maya Roinishvili, Lukasz Grzeczkowski, Ophélie Gladys Favrod, Aline Françoise Cretenoud, Janir Nuno Ramos Antunes Da Cruz, Simona Adele Garobbio, Dario Alejandro Gordillo Lopez

Often, we intuitively assume that there are common factors in life. For example, we test people with a visual acuity test to determine whether they are allowed to drive a car or not- with the implicit assumption that the acuity test is representative of vi ...

Deleterious effects of roving on learned tasks

Michael Herzog, Aaron Michael Clarke, Lukasz Grzeczkowski

In typical perceptual learning experiments, one stimulus type (e.g., a bisection stimulus offset either to the left or right) is presented per trial. In roving, two different stimulus types (e.g., a 30' and a 20' wide bisection stimulus) are randomly inter ...

No correlations between the magnitude of visual illusions

Michael Herzog, Aaron Michael Clarke, Lukasz Grzeczkowski

In cognition, audition and somatosensation, performance correlates strongly between different tasks suggesting the existence of common factors. Surprisingly, this does not hold true for vision. For example, Vernier acuity and Gabor detection correlate very ...
