Contrast sensitivity during the initiation of smooth pursuit eye movements
Eye movements challenge the perception of a stable world by inducing retinal image displacement. During saccadic eye movements visual stability is accompanied by a remapping of visual receptive fields, a compression of visual space and perceptual suppression. Here we explore whether a similar suppression changes the perception of briefly presented low contrast targets during the initiation of s...
متن کاملTemporal contrast sensitivity during smooth pursuit eye movements.
During smooth pursuit eye movements, stimuli other than the pursuit target move across the retina, and this might affect their detectability. We measured detection thresholds for vertically oriented Gabor stimuli with different temporal frequencies (1, 4, 8, 12, 16, 20, and 24 Hz) of the sinusoids. Observers kept fixation on a small target spot that was either stationary or moved horizontally a...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
15 صفحه اولMeasuring contrast sensitivity
Contrast sensitivity defines the threshold between the visible and invisible, which has obvious significance for basic and clinical vision science. Fechner's 1860 review reported that threshold contrast is 1% for a remarkably wide range of targets and conditions. While printed charts are still in use, computer testing is becoming more popular because it offers efficient adaptive measurement of ...
متن کاملContrast Sensitivity and Eye Drops
Purpose: To evaluate the influence of commonly used eye drops on contrast sensitivity (CS). Design: Prospective study. Participants: One hundred twenty volunteers were enrolled. Methods: The CS of ophthalmologically healthy individuals was evaluated at baseline examination before the instillation, 20 and 40 minutes after the instillation of diclofenac sodium and commonly used anti-glaucoma eye ...
