Intrasaccadic perception triggers pupillary constriction
It is commonly believed that vision is impaired during saccadic eye movements. However, here we report that some visual stimuli are clearly visible during saccades, and trigger a constriction of the eye's pupil. Participants viewed sinusoid gratings that changed polarity 150 times per second (every 6.67 ms). At this rate of flicker, the gratings were perceived as homogeneous surfaces while part...
متن کاملIntrasaccadic perception.
Mammalian vision has a lowpass frequency characteristic that filters out fast temporal oscillations. Thus, fast-drifting gratings cannot be detected with static eyes, but the same gratings can easily be detected by executing saccades. Because these gratings are invisible under fixation, they are useful for isolating and studying intrasaccadic perception, which is normally masked by presaccadic ...
متن کاملPupillary constriction to darkness.
Patients with congenital achromatopsia and congenital stationary night blindness have been known to show a transient pupillary constriction to darkness. We examined 50 normal subjects and 108 patients with retinal and optic nerve dysfunction to see if any had an initial pupillary constriction to darkness. We used a new infrared television apparatus. Four patients with congenital stationary nigh...
متن کاملRunning head: RELATIONAL TRIGGERS IN EVENT PERCEPTION 1 The role of relational triggers in event perception
Research exploring visual attention has demonstrated that people are aware of only a small proportion of visual properties, and that people only track these properties over a subset of moments in time. This makes it critical to understand how our perceptual system leverages its limited capacity, such that properties are tracked across views only when they can support an understanding of meaning...
متن کاملDifferential pupillary constriction and awareness in the absence of striate cortex.
The fact that the pupil constricts differentially to visual stimuli in the absence of changes in light energy makes it a valuable tool for studying normal function as well as residual capacity in hemianopic subjects. When pupillometrically effective stimuli such as equiluminant gratings or coloured patches with an abrupt onset and offset are presented to the 'blind' hemifield, a hemianopic subj...
