The Role of Uniform Textures in Making Texture Elements Visible in the Visual Periphery.

There are important differences between central and peripheral vision. With respect to shape, contours retain phenomenal sharpness, although some contours disappear if they are near other contours. This leads to some uniform textures to appear non-uniform (Honeycomb illusion, Bertamini et al.

On the relationship between foveal mask interference and mental imagery in peripheral object recognition.

A delayed foveal mask affects perception of peripheral stimuli. The effect is determined by the timing of the mask and by the similarity with the peripheral stimulus. A congruent mask enhances performance, while an incongruent one impairs it.

Foveal feedback in perceptual processing: Contamination of neural representations and task difficulty effects.

Visual object recognition was traditionally believed to rely on a hierarchical feedforward process. However, recent evidence challenges this notion by demonstrating the crucial role of foveal retinotopic cortex and feedback signals from higher-level visual areas in processing peripheral visual information. The nature of the information conveyed through foveal feedback remains a topic of debate.

The Role of Foveal Cortex in Discriminating Peripheral Stimuli: The Sketchpad Hypothesis.

Foveal (central) and peripheral vision are strongly interconnected to provide an integrated experience of the world around us. Recently, it has been suggested that there is a feedback mechanism that links foveal and peripheral vision. This peripheral-to-foveal feedback differs from other feedback mechanisms in that during visual processing a novel representation of a stimulus is formed in a different cortical region than that of the feedforward representation.

Investigating the role of the foveal cortex in peripheral object discrimination.

Peripheral object discrimination is hindered by a central dynamic mask presented between 150 and 300 ms after stimulus onset. The mask is thought to interfere with task-relevant feedback coming from higher visual areas to the foveal cortex in V1. Fan et al.

Perceptual learning improves visual functions in patients with albinistic bilateral amblyopia: A pilot study.

Background: Several visual functions are impaired in patients with oculocutaneous albinism (OCA) associated to albinistic bilateral amblyopia (ABA).

Objective: In this study, we aimed at exploring whether perceptual learning (PL) can improve visual functions in albinism.

Method: Six patients and six normal sighted controls, were trained in a contrast detection task with lateral masking.
