Microsaccades during reading
Recent research has shown that microsaccades contribute to high acuity vision. However, little is known about whether microsaccades also play a role in daily activities, such as reading, that do not involve stimuli at the limit of spatial resolution. While the functions of larger saccades in reading have been extensively examined, microsaccades are commonly regarded as oculomotor noise in this ...
متن کاملAlteration of Visual Perception prior to Microsaccades
Gaze fixation is an active process, with the incessant occurrence of tiny eye movements, including microsaccades. While the retinal consequences of microsaccades may be presumed minimal because of their minute size, a significant perceptual consequence of these movements can also stem from active extraretinal mechanisms associated with corollaries of their motor generation. Here I show that pri...
متن کاملIntegration mechanisms for heading perception.
Previous studies of heading perception suggest that human observers employ spatiotemporal pooling to accommodate noise in optic flow stimuli. Here, we investigated how spatial and temporal integration mechanisms are used for judgments of heading through a psychophysical experiment involving three different types of noise. Furthermore, we developed two ideal observer models to study the componen...
متن کاملMicrosaccades
What are they? Saccades are the rapid, jerky eye movements that we use to scan the world around us. They are necessary because high-resolution vision is only possible with the high density of photoreceptors near the center of the retina. Microsaccades resemble regular saccades in most respects except that they are tiny and occur even when we are attempting to fixate the eyes on a particular loc...
متن کاملPerception of heading without retinal optic flow.
How do we determine where we are heading during visually controlled locomotion? Psychophysical research has shown that humans are quite good at judging their travel direction, or heading, from retinal optic flow. Here we show that retinal optic flow is sufficient, but not necessary, for determining heading. By using a purely cyclopean stimulus (random dot cinematogram), we demonstrate heading p...
