Visual Attention | PDF | Attention | Experiment

Visual Attention | PDF | Attention | Experiment Abstract the visual attention is a complex perceptual cognitive activity that supports the selection and processing of essential information from visual scenes. Using attention operating characteristics for four pairs of visual discrimination tasks they show that results conform to the predictions of visual attention as a single integrated resource.

Visual Attention | PDF | Cognitive Science | Cognition Since for most humans vision is the dominant sense, visual attention is critically important for higher order cognitive functions and related deficits are a core symptom of many neuropsychiatric and neurological disorders. His research uses physiological, psychophysical and computational techniques to study the cognitive processing of visual information, such as attention, short term memory and spatial processing. It highlights the interplay between covert attention and visual short term memory, presenting findings that suggest distinct computational mechanisms for each. Here, we summarize the importance and relative contributions of different neuromodulators and neurotransmitters to the neural mechanisms of top down and bottom up attentional control.

It highlights the interplay between covert attention and visual short term memory, presenting findings that suggest distinct computational mechanisms for each. Here, we summarize the importance and relative contributions of different neuromodulators and neurotransmitters to the neural mechanisms of top down and bottom up attentional control. In this review, we briefly survey a broad swath of recent studies aimed at identifying mechanisms of attention across model species, including humans, and across different types of attention, with an eye toward identifying neural mechanisms both common and distinct. What is visual attention used for? how does attention select stimuli across space and over time? what is the role of inhibition in attentional processes? what happens when observers are asked to divide attention across several stimuli?. Advances on several fronts have refined our understanding of the neuronal mechanisms of attention. this review focuses on recent progress in understanding visual attention through single neuron recordings made in behaving subjects. In my lab, we study the behavioral and neural processes that are the cornerstones of such an infant’s developmental journey. with my colleagues at brown university, we study developmental processes including attention, memory and cognitive control from infancy through adulthood.
