In the branch of experimental psychology focused on sense, sensation, and perception, which is called psychophysics, a just-noticeable difference or JND is the amount something must be changed in order for a difference to be noticeable, detectable at least half the time. [1]
Advanced Placement (AP) Psychology (also known as AP Psych) and its corresponding exam are part of the College Board's Advanced Placement Program. This course is tailored for students interested in the field of psychology and as an opportunity to earn Advanced Placement credit or exemption from a college -level psychology course.
Ordinary least squares regression of Okun's law.Since the regression line does not miss any of the points by very much, the R 2 of the regression is relatively high.. In statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).
A new addition to the validity scales for the MMPI-2-RF includes an over reporting scale of somatic symptoms (F S) as well as revised versions of the validity scales of the MMPI-2 (VRIN-r, TRIN-r, F-r, F P-r, FBS-r, L-r, and K-r). The MMPI-2-RF does not include the S or F B scales, and the F-r scale now covers the entirety of the test. [48]
The expected value of the gamble in this example is .85 X $1000 + .15 X $0 = $850, which exceeds the expected value of $800 associated with the sure thing. [ 1 ] Research suggests that people do not evaluate prospects by the expected value of their monetary outcomes, but rather by the expected value of the subjective value of these outcomes ...
Regulatory fit intensifies responses, such as the value of a chosen object, persuasion, and job satisfaction. [ 4 ] Regulatory fit does not increase the assessment of a decision ; instead when someone feels "right" about their decision, the experience of "correctness and importance" is transferred to the ensuing assessment of the chosen object ...
In psychology case studies are most often used in clinical research to describe rare events and conditions, which contradict well established principles in the field of psychology. [1] Case studies are generally a single-case design, but can also be a multiple-case design, where replication instead of sampling is the criterion for inclusion. [2]
An R F value will always be in the range 0 to 1; if the substance moves, it can only move in the direction of the solvent flow, and cannot move faster than the solvent. For example, if particular substance in an unknown mixture travels 2.5 cm and the solvent front travels 5.0 cm, the retardation factor would be 0.50.
