Active visual perception induced by spontaneous rhythmic eye movement

Movement Coordination or Movement Interference: Visual Tracking and Spontaneous Coordination Modulate Rhythmic Movement Interference

When an actor performs a rhythmic limb movement while observing a spatially incongruent movement he or she exhibits increased movement orthogonal to the instructed motion. Known as rhythmic movement interference, this phenomenon has been interpreted as a motor contagion effect, whereby observing the incongruent movement interferes with the intended movement and results in a motor production err...

Viewing task influences eye movement control during active scene perception.

Expanding on the seminal work of G. Buswell (1935) and I. A. Yarbus (1967), we investigated how task instruction influences specific parameters of eye movement control. In the present study, 20 participants viewed color photographs of natural scenes under two instruction sets: visual search and memorization. Results showed that task influenced a number of eye movement measures including the num...

Rhythmic raiding of refrigerator related to rapid eye movement sleep.

Eye movements reset visual perception.

Human vision uses saccadic eye movements to rapidly shift the sensitive foveal portion of our retina to objects of interest. For vision to function properly amidst these ballistic eye movements, a mechanism is needed to extract discrete percepts on each fixation from the continuous stream of neural activity that spans fixations. The speed of visual parsing is crucial because human behaviors ran...

Movement perception during voluntary saccadic eye movements.

In order to elucidate the stabilization mechanism of the visual perception duringvoluntary eye movements the perception of a moving object during a eye saccade was investi-gated in humansubjects. The results were analyzed in terms of velocity and displacement percep-tion channels. The experimental results indicate that during voluntary saccades there is nosuppression of movement...
