overt attention involve instructing the participant to attend to a particular region of the field via a centrally presented cue (e.g., Heinze et al., 1990, 1994; Luck et al., 1990; Mangun et al., 1997; Kelley et al., 2008; Tamber-Rosenau et al., 2011), and so can be considered as an endogenous direction of attention.

behavior that is not directly observable and can only be inferred by the observer or reported by the subject. For example, imagining something is covert behavior.
What causes spatial attention deficits?
The core spatial deficit, a bias in spatial attention and salience mapped in an egocentric coordinate frame, is caused by the dysfunction of a dorsal frontal-parietal network that controls attention and eye movements and represent stimulus saliency.
Does V1 control spatial attention?
The modulation due to spatial attention is present throughout the early visual areas V1, V2, V3, and VP, and varies with the attended location. These findings demonstrate that early visual areas are modulated by at least two types of endogenous signals, each with distinct cortical distributions.
What is the difference between overt and covert orienting?
Overt and covert orienting. Attention may be differentiated into “overt” versus “covert” orienting. Overt orienting is the act of selectively attending to an item or location over others by moving the eyes to point in that direction.
