Attention is therefore externally guided by a stimulus, resulting in a reflexive saccade. Endogenous orienting is the voluntary movement that occurs in order for one to focus visual attention on a goal-driven stimulus. [28] Thus, the focus of attention of the perceiver can be manipulated by the demands of a task.
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.
A parent and child engage in joint attention. Joint attention or shared attention is the shared focus of two individuals on an object. It is achieved when one individual alerts another to an object by means of eye-gazing, pointing or other verbal or non-verbal indications. An individual gazes at another individual, points to an object and then ...
In cognitive psychology there are at least two models which describe how visual attention operates. These models may be considered metaphors which are used to describe internal processes and to generate hypotheses that are falsifiable. Generally speaking, visual attention is thought to operate as a two-stage process. [23]
When considering the nature and effects of object-based attention, [9] three research theories are commonly mentioned; [10] these are presented below. Consideration is then given to the enhancing effect of object-based attention on memory, and its inhibitory effect during certain kinds of visual search.
Sources of attention in the brain create a system of three networks: alertness (maintaining awareness), orientation (information from sensory input), and executive control (resolving conflict). [2] These three networks have been studied using experimental designs involving adults, children, and monkeys, with and without abnormalities of ...
Generally, the test is 21.6 minutes long and is presented as a simple, yet boring, computer game. The test is used to measure a number of variables involving the test taker's response to either a visual or auditory stimulus. These measurements are then compared to the measurements of a group of people without attention disorders who took the T ...
Anne Marie Treisman (née Taylor; 27 February 1935 – 9 February 2018) was an English psychologist who specialised in cognitive psychology. Treisman researched visual attention, object perception, and memory. One of her most influential ideas is the feature integration theory of attention, first published with Garry Gelade in 1980.
