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 ...
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.
Results showed overlap in activated areas for overt and covert attention shifts, mainly in the parietal and frontal lobes. However, one area was shown to be specific to covert attention, which was the right dorsolateral cortex; typically associated with voluntary attention shifts and working memory .
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.
Covert desensitization" associates an aversive stimulus with a behavior that the client wishes to reduce or eliminate. This is achieved by imagining the target behavior followed by imagining an aversive consequence. "Covert extinction" attempts to reduce a behavior by imagining the target behavior while imagining that the reinforcer does not occur.
Triangulation may be overt, which is more commonly seen in high-conflict families, or covert. [ 4 ] A 2016 longitudinal study of adolescent relationship skills found that teens who were triangulated into parental conflicts more frequently used positive conflict resolution techniques with their own dating partner, but were also more likely to ...

These experiments have used behavioral and physiological measures in order to demonstrate covert facial recognition. A common physiological measure that is used is the measure of autonomic activity by using skin-conductance responses (SCR) which show a larger response in individuals with prosopagnosia who are shown pictures of familiar faces ...
