Overt Responses during Covert Orienting
A distributed network of cortical and subcortical brain areas controls our oculomotor behavior. This network includes the superior colliculus (SC), which coordinates an ancient visual grasp reflex via outputs that ramify widely within the brainstem and spinal cord, accessing saccadic and other premotor and autonomic circuits. In this Review, we discuss recent results correlating subliminal SC a...
متن کاملCharacteristics of covert and overt visual orienting: Evidence from attentional and oculomotor capture.
Five visual search experiments found oculomotor and attentional capture consistent with predictions of contingent orienting, contrary to claims that oculomotor capture is purely stimulus driven. Separate saccade and attend-only conditions contained a color target appearing either singly, with an onset or color distractor, or both. In singleton mode, onsets produced oculomotor and attentional ca...
متن کاملTop-down control over biased competition during covert spatial orienting.
Larger benefits of spatial attention are observed when distractor interference is prevalent, supporting the view that spatial selection facilitates visual processing by suppressing distractor interference. The present work shows that cuing effects with identical visual displays can grow substantially as the probability of distractor interference increases. The probability of interference had no...
متن کاملThe Interaction of Overt and Covert Attention of Children During Performing a Targeting Task
It has been shown in various researches that the focus of attention and quiet eye duration (QED) are effective variables on the performance of targeting tasks. However, the impact of these variables on motor skills in children needs more research; Therefore, the purpose of this study was to investigate the effect of different attentional focus instruction on QED and accuracy of children's darts...
متن کاملForgiven But Not Forgotten: Covert Uncertainty in Overt Responses and the Paradox of Defection-Despite-Trust COVERT UNCERTAINTY OVERT RESPONSES R TTE, CHANDR SHEKARAN, TAX, GREWAL
Despite the widespread belief that trust is a critical determinant of loyalty, empirical and anecdotal evidence calls into question the real-world robustness of the trust–loyalty link. An important reason for the fuzzy nature of the trust–loyalty link may be the fuzzy nature of trust itself. That is, stated trust judgments embody both a magnitude dimension (i.e., the position along a favorable-...
