Two-alternative forced choice (2AFC) is a method for measuring the sensitivity of a person or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input.
He then describes how ICR developed a series of experiments as rides, created to test and expand a subject's mental growth. The first was the 1977 prototype 6 G-force Vertical Centrifuge which self-destructed in 1978. ICR then joined forces with a company that built and distributed amusement park rides to develop projects and gain funding.
Centrifugal force is a fictitious force in Newtonian mechanics (also called an "inertial" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed radially away from the axis of rotation of the frame.
Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, [6] or measures of interoceptive ...
The term "behavioural despair test" bears an anthropomorphic connotation and is a somewhat subjective description as it is uncertain whether the test reliably gauges mood or despair. Strictly speaking, the descriptive term "forced swimming test" is preferred by researchers. [ 8 ]
Stevens' power law is an empirical relationship in psychophysics between an increased intensity or strength in a physical stimulus and the perceived magnitude increase in the sensation created by the stimulus.
In psychology, ipsative questionnaires (/ ˈ ɪ p s ə t ɪ v /; from Latin: ipse, 'of the self') are those where the sum of scale scores from each respondent adds to a constant value. [1] Sometimes called a forced-choice scale , this measure contrasts Likert-type scales in which respondents score—often from 1 to 5—how much they agree with ...
The concepts of fluid intelligence (g f) and crystallized intelligence (g c) were introduced in 1943 by the psychologist Raymond Cattell. [1] [2] [3] According to Cattell's psychometrically-based theory, general intelligence (g) is subdivided into g f and g c.
