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.
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 ...
Attention may be differentiated into "overt" versus "covert" orienting. [50] Overt orienting is the act of selectively attending to an item or location over others by moving the eyes to point in that direction. [51] Overt orienting can be directly observed in the form of eye movements.
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 .
Level 2 Security (L2S) EMBEDDED Data—Level 2 Security improves upon the physical security mechanisms of Level 1 Security by taking information protection to a covert and embedded level. This prevents casual intruders from gaining access to, for example, encoded confidential information inside an embedded chip or other means of encoding.
The arguments for doing so include having centralized functions for monitoring covert action and clandestine HUMINT and making sure they do not conflict, as well as avoiding duplication in common services such as cover identity support, counterespionage, and secret communications. The arguments against doing so suggest that the management of ...
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.
[6] [7] There are thus the concepts of overt and covert prestige. Overt prestige is related to standard and "formal" language features, and expresses power and status; covert prestige is related more to vernacular and often patois, and expresses solidarity, community and group identity more than authority.
