Contrast is a feature of visual stimuli that characterizes the difference in brightness between dark and light regions of an image. Perception of contrast is affected by the temporal frequency and spatial frequency properties of a stimulus, and the sensitivity to contrast in sine wave stimuli is characterized by the contrast sensitivity function.
Apperceptive agnosia is a neurological disorder characterized by failures in recognition due to a failure of perception.In contrast, associative agnosia is a type of agnosia where perception occurs but recognition still does not occur. [1]
A contrast effect is the enhancement or diminishment, relative to normal, of perception, cognition or related performance as a result of successive (immediately previous) or simultaneous exposure to a stimulus of lesser or greater value in the same dimension. (Here, normal perception, cognition or performance is that which would be obtained in ...
Colour and contrast are important. [5] The brain's colour processing is distributed in such a way that it is more difficult to damage, so people with CVI usually retain full perception of colour. This can be used to advantage by colour-coding objects that might be hard to identify otherwise.
The Chubb illusion is similar to another visual illusion, the contrast effect.The contrast effect is an illusion in which the perceived brightness or luminance of an identical central visual target form on a larger uniform background varies to the test subject depending on the ratio of the central form's luminance to that of its background. [4]
The mental status examination (MSE) is an important part of the clinical assessment process in neurological and psychiatric practice. It is a structured way of observing and describing a patient's psychological functioning at a given point in time, under the domains of appearance, attitude, behavior, mood and affect, speech, thought process, thought content, perception, cognition, insight, and ...
Behavior modification is a treatment approach that uses respondent and operant conditioning to change behavior. Based on methodological behaviorism, [1] overt behavior is modified with (antecedent) stimulus control and consequences, including positive and negative reinforcement contingencies to increase desirable behavior, as well as positive and negative punishment, and extinction to reduce ...
An example of a cognitive bias modification for interpretation (CBM–I) paradigm utilized in MindTrails, an online program developed by anxiety researchers at the University of Virginia. The program displays a cognitive task that disambiguates a scenario to be either positively or negatively valenced (correct responses highlighted in orange).
