Bilateral long-range interaction between right and left visual hemifield
Long-range interaction has been reported to be limited in space within a few degrees. Here, we present a new type of interaction by means of a bilateral configuration using two Gabor signals (GSs). Two horizontally oriented GSs, the first defined as a cue and the second as a probe, appeared in the right and left peripheral visual fields in mirror symmetrical regions. The detection threshold of ...

abstract the present study tried to investigate the effect of visual aids (films) on the development of the speech act of disagreement among iranian efl intermediate learners. to this end, the researcher selected 40 homogeneous intermediate learners based on their scores on oxford placement test. .the subjects then divided into control group and experimental group. both classes were tested by ...
Visual Hemifield Loss in Thalamic Hematoma
A 45 year old hypertensive patient presented to the emergency medical room (EMR) with sudden onset of severe headache, episode of vomiting, visual loss and confusion. A C.T scan and MRI brain was done revealing a large hematoma in the region of posterior part of left thalamus. The patient was disoriented in time, place and had right visual field hemianopia. The headache and higher functions bec...
متن کاملTemporal limits of long-range phase discrimination across the visual field
When two flickering sources are far enough apart to avoid low-level motion signals, phase judgment relies on the temporal individuation of the light and dark phases of each source. The highest rate at which the individuation can be maintained has been referred to as Gestalt flicker fusion [Van de Grind, W. A., Grüsser, O. -J., & Lunkenheimer, H. U. (1973). Temporal transfer properties of the af...
متن کاملLong-range interactions in visual perception.
Classical receptive-field concepts have been used to explain local perceptual effects such as border contrast and Mach bands, but are not sufficient to explain global perceptual effects. Examples are the perception of illusory contours, area contrast, color constancy, depth planes, coherent motion and texture contrast. These diverse effects require neurophysiological mechanisms within the visua...
