Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior (in practice often constituted by task performance).
[1] [2] [3] It is also a basic principle that guides modern research in perception. [4] [5] The ideal observer is a theoretical system that performs a specific task in an optimal way. If there is uncertainty in the task, then perfect performance is impossible and the ideal observer will make errors.
At the very darkest background levels (≲ 10 − 5 cd m −2, approximately 25 mag arcsec −2) [24] the curves are flat - this is where the only visual perception is the observer's own neural noise ('dark light'). In the intermediate range, a portion can be approximated by the De Vries - Rose law, related to Ricco's law.

Representation of the stages of processing in a typical reaction time paradigm. Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations.
The consciousness and binding problem is the problem of how objects, background, and abstract or emotional features are combined into a single experience. [1] The binding problem refers to the overall encoding of our brain circuits for the combination of decisions, actions, and perception. It is considered a "problem" because no complete model ...
