TL;DR: It is found that sensitivity for detection of the peripheral grating depends on the similarity of the spatial frequencies and orientations between the foveal and peripheral stimuli.

TL;DR: The concept of covert visual attention was introduced in this article, where visual attention can be directed covertly to different locations in the visual field while the eyes themselves are maintained in a fixed position.
Abstract: Publisher Summary In naturally occurring search situations, eye movements form the most effective way of sampling the visual field. This chapter analyzes the concept of “covert visual attention”. Visual attention can be directed covertly to different locations in the visual field while the eyes themselves are maintained in a fixed position. Redirection of attention in this way gives clear benefits when the speed and accuracy of visual processing at the attended location are measured. The feature integration theory distinguishes between parallel and serial processes in search. Certain search tasks seem easy and effortless, while others tasks seem more arduous and time consuming. Two important assumptions of the theory are “spatial homogeneity of processing”, and “rapid attentional movements”. The visual system is organized so that exquisite detail processing occurs in the central foveal region. Processing ability shows a systematic decline outside this region. The decline is mainly attributable to the properties of the retino cortical mapping function. When more than one stimulus is present in neighboring regions of the peripheral visual field, such stimuli act in a reciprocally interfering manner to produce a further decline in recognition.

TL;DR: The restoration of the ELM is closely associated with that of the IS/OS junction and the preoperativeIS/OS or ELM defect was associated with the postoperative foveal sensitivity, which may reflect the morphologic and functional recovery of thefoveal photoreceptors in surgically closed MHs.

TL;DR: It is suggested that non-retinotopic high brain areas may be responsible for orientation learning, consistent with the extant neurophysiological data.

TL;DR: Although the saccades of patients consistently directed images to PRL, the sAccades still had the latency and dynamic characteristics of non-foveating s Accades, apparently, patients with macular scotoma suppress rather than adapt a foveated saccade mechanism.
