A psychometric function is an inferential psychometric model applied in detection and discrimination tasks. It models the relationship between a given feature of a physical stimulus , e.g. velocity, duration, brightness, weight etc., and forced-choice responses of a human or animal test subject.
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement.Psychometrics generally covers specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. [1]
In contrast to other cognitive test batteries and in addition to its psychometric measures, the later versions of CFS includes detailed recording of every step of the full response process in all tests (collection of qualitative data to support interpretation of every psychometric outcome). Cognitive Function Scanner was one of the first ...
Neuropsychological tests are designed to assess behaviors that are linked to brain structure and function. An examiner, following strict pre-set procedures, administers the test to a single person in a quiet room largely free of distractions. [1] An example of a widely-used neuropsychological test is the Stroop test.

(The expression "a mathematical function of person and item parameters" is analogous to Lewin's equation, B = f(P, E), which asserts that behavior is a function of the person in their environment.) The ...

[1] Tests are used for research into brain function and in a clinical setting for the diagnosis of deficits. They usually involve the systematic administration of clearly ...
