Visual experience affects handedness

Visual experience affects handedness.

In birds, a lateralised visual input during early development importantly modulates morphological and functional asymmetries of vision. We tested the hypothesis that human handedness similarly results from a combination of inborn and experience-driven factors by analysing sidedness in children suffering from congenital muscular torticollis. These children display a permanently tilted asymmetric...

visual experience of prehistoric human

this research wants to consider the formation process of outline and spotted shapes in prehistoric periods. the light and the various form of its reflection, which appears as a shadow, silhouette and lightfast, and the way of facing human with nature surrounding him, is the theoretical base of this paper. light is one of the important elements in nature which help human to know and comprehend i...

Effects of Handedness on Visual Sensitivity in Perihand Space

Recent studies have shown that changes in visual processing in perihand space are limited to the area around the right hand, at least in right-handers. One explanation for these findings is that perception is altered at locations where action is more likely to occur. To test this notion, we asked both right- and left-handers to perform an unspeeded visual discrimination task under four hand-pos...

How Visual Feedback Affects Movements

Good continuation affects visual detection

This research shows that the principle of good continuation can predict forced-choice detection of an element imbedded in a briefly presented visual array. The present experiments show the configurational effect in a manner that is difficult for feature-analytic theories to explain. The research adds good continuation to good form as Gestalt-like organizational principles affecting detection pe...
