Visual psychophysics
Visual processes in the brain enable us to make sense of the complex, ever-changing array of shapes and colours that arrives at our eyes. Psychophysics is the research strategy that seeks to understand these processes, by testing the relationship between the ‘psychic’ — what an observer sees and reports — and variations in the physical pattern of light and colour. For 19th century pioneers such...
متن کاملVisual Psychophysics in Diabetic Retinopathy
INTRODUCTION Irreversible and severe visual loss may represent the end of long lasting diabetic retin-opathy. The progression of visual impairment and the quantification of final residual visual function are currently determined by means of diagnostic tests which rely on the physiological and mathematical principles of psychophysics. The best known among these tests is the quantification of vis...
متن کاملThe psychophysics of visual search
Most theories of visual search emphasize issues of limited versus unlimited capacity and serial versus parallel processing. In the present article, we suggest a broader framework based on two principles, one empirical and one theoretical. The empirical principle is to focus on conditions at the intersection of visual search and the simple detection and discrimination paradigms of spatial vision...
متن کاملHigh-Yield Methods for Accurate Two-Alternative Visual Psychophysics in Head-Fixed Mice
Research in neuroscience increasingly relies on the mouse, a mammalian species that affords unparalleled genetic tractability and brain atlases. Here, we introduce high-yield methods for probing mouse visual decisions. Mice are head-fixed, facilitating repeatable visual stimulation, eye tracking, and brain access. They turn a steering wheel to make two alternative choices, forced or unforced. L...
متن کاملVisual Recognition: Computational Models and Human Psychophysics
Object and scene recognition is one of the most essential functionalities of human vision. It is also of fundamental importance for machines to be able to learn and recognize meaningful objects and scenes. In this thesis, we explore the following four aspects of object and scene recognition. It is well known that humans can be “blind” even to major aspects of natural scenes when we attend elsew...
