Saccadic eye movements and cognition.
Scanning of the visual scene is an important selective process in visual perception. In this article we argue that eye-movement data provide an excellent on-line indication of the cognitive processes underlying visual search and reading. We outline some recent advances from physiological investigations of saccadic eye-movement control before focusing on eye-movement behaviour in visual search a...
متن کاملStable individual differences across images in human saccadic eye movements.
Individual differences in eye movements during picture viewing were examined across image format, content, and foveal quality in 3 experiments. Experiment 1 demonstrated that an individual's fixation durations were strongly related across 3 types of scene formats and that saccade amplitudes followed the same pattern. In Experiment 2, a similar relationship was observed for fixation durations ac...
متن کاملKinematic Calibration for Saccadic Eye Movements
The visual perception system of humanoid robots should provide sensorial information that fulfills the requirements imposed by perceptual tasks in natural environments. One prerequisite for such systems is the ability to observe the environment by actively moving its visual sensors. This ability allows to implement two essential behaviors for a cognitive visual system: smooth pursuit and saccad...
متن کاملNeural control of saccadic eye movements.
Recent experiments report that localization of brief targets presented during an ongoing saccade is not accurate. Because interpretations of these findings challenge an important tenet of existing oculomotor models, we examine the methodological and logical bases of these conclusions. Also, we review recent research related to the roles of the frontal eye fields and cerebellum in the control of...
متن کاملSaccadic Eye Movements in Depressed Elderly Patients
The primary aim of this study was to characterize oculomotor performances in elderly depressed patients. The second aim was to investigate whether cognitive inhibition measured by the antisaccade task was associated with a psychomotor retardation or rather with a more specific cognitive-motor inhibition deficit. Twenty patients with a major depressive disorder and forty-seven healthy subjects p...
