Attention, 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 کاملAdaptation state of the local-motion-pooling units determines the nature of the motion aftereffect to transparent motion
When observers adapt to a transparent-motion stimulus, the resulting motion aftereffect (MAE) is typically in the direction opposite to the vector average of the component directions. It has been proposed that the reason for this is that it is the adaptation state at the local-level (i.e. of the local-motion-pooling units) that determines the nature of the MAE (Vidnyanszky et al. Trends in Cogn...
متن کاملAnother perspective on the visual motion aftereffect.
Prolonged adaptation to motion in a given direction produces distinctly different visual motion aftereffects (MAEs) when viewing static vs. dynamic test displays. The dynamic MAE can be exactly simulated by real motion, whereas the static MAE cannot. In addition, the magnitude of the dynamic MAE depends on the bandwidth of motion directions experienced during adaptation, whereas the static MAE ...
متن کاملGamma oscillations underlying the visual motion aftereffect
After having been exposed to strong visual motion in one direction, a subsequently presented stationary visual scene seems to move in the opposite direction. This motion aftereffect (MAE) is usually ascribed to short-term functional changes in cortical areas involved in visual motion analysis akin to adaptation. Using magnetoencephalography (MEG), we show increased global field activity due to ...
متن کاملMotion adaptation shifts apparent position without the motion aftereffect.
Adaptation to motion can produce effects on both the perceived motion (the motion aftereffect) and the position (McGraw, Whitaker, Skillen, & Chung, 2002; Nishida & Johnston, 1999; Snowden, 1998; Whitaker, McGraw, & Pearson, 1999) of a subsequently viewed test stimulus. The position shift can be interpreted as a consequence of the motion aftereffect. For example, as the motion within a stationa...
