Saccade Target Selection During Visual Search
Five experiments are reported in which eye movements were recorded while subjects carried out a visual search task. The aim was to investigate whether an accurate initial target directed saccade could be programmed. In experiments 1-2, subjects moved their eyes to targets defined by colour, which were presented with seven non-targets in a circular array. Accurate saccades with short latencies w...
متن کاملTime Course of Target Recognition in Visual Search
VISUAL SEARCH IS A UBIQUITOUS TASK OF GREAT IMPORTANCE: it allows us to quickly find the objects that we are looking for. During active search for an object (target), eye movements are made to different parts of the scene. Fixation locations are chosen based on a combination of information about the target and the visual input. At the end of a successful search, the eyes typically fixate on the...
متن کاملTime course of motor preparation during visual search with flexible stimulus-response association.
Whether allocation of visuospatial attention can be divorced from saccade preparation has been the subject of intense research efforts. A variant of the visual search paradigm, in which a feature singleton indicates that the correct saccade should be directed to it (prosaccade) or to the opposite distractor (antisaccade), has been influential in addressing this core topic. We performed a causal...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Neural Mechanisms of Top-down Selection during Visual Search
The brain’s representation of visual information depends greatly on the behavioral relevance of the viewed stimuli. While in some instances behavioral significance is derived from conspicuity, in many situations significance depends on top-down factors such as the viewer’s goals and knowledge. Studies combining neural recordings and behavioral observations have begun to elucidate how the brain ...
