Attention-based motion perception and motion adaptation: What does attention contribute?
Attention-based motion perception refers to the phenomenon that a stimulus with ambiguous motion energy can be seen to move in a direction that is under attentive control of the observer. The role of attention is obvious when the stimulus is ambiguous: it makes the stimulus move in one direction. The goal of the current experiment is to investigate what the contribution of attention under atten...
متن کاملCovert Attention and Motion Perception
Explicit perception requires attentional modulation of the stimulus signals, whether in motion or not. As the covert attentional process is relatively slow in comparison with specific encoding of the stimulus signals then certain dissociation between objective stimulus position and subjective representation of this position can be evidenced at the onset of stimulation. Several psychophysical ph...
متن کاملMotion adaptation does not depend on attention to the adaptor
Prolonged inspection of moving stimuli causes stationary stimuli to appear moving in the opposite direction to the adapting stimulus (the Waterfall effect). It has been claimed that distracting the viewer's attention from the adapting stimulus by a secondary task reduces the strength of adaptation. However, the method used to show the effect of distraction (the duration of the aftereffect) is p...
متن کاملAttention, Adaptation, and the Motion Aftereffect
Activation of the human visual motion area V5/MT was previously thought to be the basis of the motion aftereffect. New findings suggest that previous observations were confounded by attention and arousal, providing evidence that adaptation of directionally selective neurons in area V5/MT represents the fundamental substrate for the motion aftereffect.
متن کاملAttention modulates perception of transparent motion
Human observers can extract a given motion direction from sets of random dots moving simultaneously in two or more directions in the same region of the visual field, a phenomenon referred to as motion transparency. As a necessary condition for separating transparent motion directions, low level encoding of local motion signals must generate frequency distributions of local directions with separ...
