The brain pathway that orients visual attention to a stimulus is referred to as the orienting system.There are two main types of visual orientations, covert (exogenous) which occurs when a salient environmental change causes a shift in attention and overt (endogenous) which occurs when the individual makes a conscious decision to orient attention to a stimuli [1] During a covert orientation of ...
This method is used to differentiate overt and covert attention. Overt attention involves directed eye movements, known as saccades, to consciously focus the eye on a target stimulus. 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 ...
Covert orienting has the potential to affect the output of perceptual processes by governing attention to particular items or locations (for example, the activity of a V4 neuron whose receptive field lies on an attended stimuli will be enhanced by covert attention) [53] but does not influence the information that is processed by the senses ...
The sender's overt (and covert) communications are affected by the overt and covert communications of the receiver, and vice versa. IDT explores the interrelation between the sender's communicative meaning and the receiver's thoughts and behavior in deceptive exchanges.
However, it is this high visual acuity that is needed to perform actions such as reading words or recognizing facial features, for example. Therefore, the eyes must continually move in order to direct the fovea to the desired goal. Prior to an overt eye movement, where the eyes move to a target location, covert attention shifts to this location.
Behavior modification is a treatment approach that uses respondent and operant conditioning to change behavior. Based on methodological behaviorism, [1] overt behavior is modified with (antecedent) stimulus control and consequences, including positive and negative reinforcement contingencies to increase desirable behavior, as well as positive and negative punishment, and extinction to reduce ...
Systematic desensitization, (relaxation training paired with graded exposure therapy), is a behavior therapy developed by the psychiatrist Joseph Wolpe. It is used when a phobia or anxiety disorder is maintained by classical conditioning. It shares the same elements of both cognitive-behavioral therapy and applied behavior analysis.
The original sample of children (ages 6–11) in 1983 consisted of 1,125 subjects. Three main areas were studied in the subjects: status violations, overt behavior, and covert behavior. Children exhibiting overt behavior were found to have two times greater risk for covert behavior as an adolescent and three times greater risk for it in adulthood.
