Rapid Serial Visual Presentation
Rapid serial visual presentation (RSVP) is a scientific method for studying the timing of vision. In RSVP, a sequence of stimuli are shown to an observer at one location in their visual field. The observer is instructed to report one of these stimuli - the target - which has a feature that differentiates it from the rest of the stream. For instance, observers may see a sequence of stimuli consisting of grey letters with the exception of one red letter. They are told to report the red letter. People make errors in this task in the form of reports of stimuli that occurred before or after the target. The position in time of the letter they report, relative to the target, is an estimate of the timing of visual selection on that trial. The term, and methodologies to study it, was first introduced by Mary C. Potter. Peripheral reading Peripheral reading is vital to those suffering from central field loss, which is most commonly seen in the elderly. Factors which might limit one's per ...

Visual Spatial Attention
Visual spatial attention is a form of visual attention that involves directing attention to a location in space. Similar to its temporal counterpart visual temporal attention, these attention modules have been widely implemented in video analytics in computer vision to provide enhanced performance and human interpretable explanation of deep learning models. Spatial attention allows humans to selectively process visual information through prioritization of an area within the visual field. A region of space within the visual field is selected for attention and the information within this region then receives further processing. Research shows that when spatial attention is evoked, an observer is typically faster and more accurate at detecting a target that appears in an expected location compared to an unexpected location. Attention is guided even more quickly to unexpected locations, when these locations are made salient by external visual inputs (such as a sudden flash). Accordi ...

Central Scotoma
A scotoma is an area of partial alteration in the field of vision consisting of a partially diminished or entirely degenerated visual acuity that is surrounded by a field of normal – or relatively well-preserved – vision. Every normal mammalian eye has a scotoma in its field of vision, usually termed its blind spot. This is a location with no photoreceptor cells, where the retinal ganglion cell axons that compose the optic nerve exit the retina. This location is called the optic disc. There is no direct conscious awareness of visual scotomas. They are simply regions of reduced information within the visual field. Rather than recognizing an incomplete image, patients with scotomas report that things "disappear" on them. The presence of the blind spot scotoma can be demonstrated subjectively by covering one eye, carefully holding fixation with the open eye, and placing an object (such as one's thumb) in the lateral and horizontal visual field, about 15 degrees from fixatio ...

Attentional Blink
Attentional blink (AB) is a psychological effect where people struggle to notice a second visual target in a rapid sequence if it appears 200 to 500 milliseconds after the first and is followed by distractions. For instance, in a fast stream of letters like "B, X, C, K," if "X" and "K" are targets to spot, "K" is often missed if a letter like "C" comes between them. The AB is typically measured by using rapid serial visual presentation (RSVP) tasks (tasks where items flash quickly one after another), where participants often fail to detect a second salient target if it is presented within the blink. The AB has also been observed using two backward-masked targets and auditory stimuli. The term attentional blink was first used in 1992, although the phenomenon was probably known before. Research The precise adaptive significance behind the attentional blink is unknown, but it is thought to be a product of a two-stage visual processing system attempting to allocate episodic context ...

Information Visualization
Data and information visualization (data viz/vis or info viz/vis) is the practice of designing and creating Graphics, graphic or visual Representation (arts), representations of a large amount of complex quantitative and qualitative data and information with the help of static, dynamic or interactive visual items. Typically based on data and information collected from a certain domain of expertise, these visualizations are intended for a broader audience to help them visually explore and discover, quickly understand, interpret and gain important insights into otherwise difficult-to-identify structures, relationships, correlations, local and global patterns, trends, variations, constancy, clusters, outliers and unusual groupings within data (''exploratory visualization''). When intended for the general public (mass communication) to convey a concise version of known, specific information in a clear and engaging manner (''presentational'' or ''explanatory visualization''), it is t ...
