Global attention facilitates the planning, but not execution of goal-directed reaches
In daily life, humans interact with multiple objects in complex environments. A large body of literature demonstrates that target selection is biased toward recently attended features, such that reaches are faster and trajectory curvature is reduced when target features (i.e., color) are repeated (priming of pop-out). In the real world, however, objects are comprised of several features-some of...
متن کاملResponse of the Pre-oriented Goal-directed Attention to Usual and Unusual Distractors: A Preliminary Study
Introduction: In this study, we investigated the distraction power of the unusual and usual images on the attention of 20 healthy primary school children. Methods: Our study was different from previous ones in that the participants were asked to fix the initial position of their attention on a pre-defined location after being presented with unusual images as distractors. The goals were prese...
متن کاملReflexive Spatial Attention to Goal Directed Reaching
Social interaction involves cues such as gaze direction, head orientation, and pointing gestures that serve to automatically orient attention to a specific referent or spatial location. In this paper we demonstrate that an observed reaching action similarly results in a reflexive shift in attention as evidenced by faster responses that are congruent with the direction of the reach, than respons...
متن کاملLesions of medial prefrontal cortex disrupt the acquisition but not the expression of goal-directed learning.
Several studies have established that pretraining lesions of the medial prefrontal cortex (mPFC) render instrumental actions insensitive to devaluation of the instrumental outcome and degradation of the action-outcome contingency. Nevertheless, it remains to be assessed whether the involvement of the mPFC in goal-directed action is limited to the acquisition or to the expression of the action-o...
متن کاملDissociable Effects of Salience on Attention and Goal-Directed Action
Everyday behavior frequently involves encounters with multiple objects that compete for selection. For example, driving a car requires constant shifts of attention between oncoming traffic, rearview mirrors, and traffic signs and signals, among other objects. Behavioral goals often drive this selection process [1, 2]; however, they are not the sole determinant of selection. Physically salient o...
