The effect of object-based attention on memory has also received increasing attention. Three experiments conducted by Bao and colleagues have shown that the binding of different information to a single object improves the manipulation of that information within working memory, suggesting a relationship between outer visual attention and ...
Studies have been conducted to examine whether the contextual cueing effect would be accentuated when the targets are more salient; evidence on the influence is undecided. Geyer et al. (2010) conducted experiments which required search for a single target that differed significantly in colour compared to the rest of the items. [ 15 ]
The spotlight effect is an extension of several psychological phenomena. Among these is the phenomenon known as anchoring and adjustment, which suggests that individuals will use their own internal feelings of anxiety and the accompanying self-representation as an anchor, then insufficiently correct for the fact that others are less privy to those feelings than they are themselves.
The Hawthorne effect occurs when research study participants know they are being studied and alter their performance because of the attention they receive from the experimenters. The John Henry effect , a specific form of Hawthorne effect, occurs when the participants in the control group alter their behavior out of awareness that they are in ...
Feature integration theory is a theory of attention developed in 1980 by Anne Treisman and Garry Gelade that suggests that when perceiving a stimulus, features are "registered early, automatically, and in parallel, while objects are identified separately" and at a later stage in processing.
"THE CAT" is a classic example of context effect. We have little trouble reading "H" and "A" in their appropriate contexts, even though they take on the same form in each word. A context effect is an aspect of cognitive psychology that describes the influence of environmental factors on one's perception of a stimulus. [1]
By contrast, other studies have indicated that the effects of sleep deprivation on cognitive performance, specifically sustained visual attention, are more global and bilateral in nature (as opposed to more lateralized deficit explanations). In a study using the Choice Visual Perception Task, subjects were exposed to stimuli appearing in ...
In attention research, one prominent theory attempting to explain how visual attention is shifted is the moving-spotlight theory. The primary idea being that attention is like a movable spotlight that is directed towards intended targets, focusing on each target in a serial manner.
