Attention seeking behavior is defined in the DSM-5 as "engaging in behavior designed to attract notice and to make oneself the focus of others' attention and admiration". [ 1 ] : 780 This definition does not ascribe a motivation to the behavior and assumes a human actor, although the term "attention seeking" sometimes also assumes a motive of ...
With manual groping behavior (MGB), the patient's hand or eye is attracted to an object and follows it in a magnetic manner while manipulating the object. [5] This behavior is involuntary and occurs constantly except for the brief stops due to diverted attention. Similar to the grasp reflex, MGB is normal in infants but presents as a symptom in ...
Object-based attention refers to the relationship between an ‘object’ representation and a person’s visually stimulated, selective attention, as opposed to a relationship involving either a spatial or a feature representation; although these types of selective attention are not necessarily mutually exclusive. [1]
[5] [2] The sensory enhancement theory of object-based attention proposes that when attention is directed to a cued object, the quality of the object’s physical representations improve [6] [7] [8] because the spread of attention facilitates the efficiency of processing the features of the object as a whole.
When the image hits the fovea, it is highly magnified, facilitating object recognition. The images in the periphery are less clear but help to create a complete image used for scene perception. [7] [8] [9] Visual scene segmentation is a pre-attentive process where stimuli are grouped together into specific objects against a background. [10]
Covert attention involves mental focus or attention to an object without significant eye movement, and is the predominant area of interest when using the Posner cueing task for research. By making 80% trials valid and 20% trials invalid, Posner encourages covert shifts of attention to take place in response to cueing.
Attention is best described as the sustained focus of cognitive resources on information while filtering or ignoring extraneous information. Attention is a very basic function that often is a precursor to all other neurological/cognitive functions. As is frequently the case, clinical models of attention differ from investigation models.
Research has also been done on attention to non-object based things like motion. When directing attention to a feature like motion, neuronal activity increases in areas specific for the feature. When visually searching for a non-spatial feature or a perceptual feature, selectively enhancing the sensitivity to that specific feature plays a role ...
