e. 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).
Ambiguous images are important to the field of psychology because they are often research tools used in experiments. [3] There is varying evidence on whether ambiguous images can be represented mentally, [ 4 ] but a majority of research has theorized that mental images cannot be ambiguous.
An example of "beauty in method"—a simple and elegant visual descriptor of the Pythagorean theorem. Mathematical beauty is the aesthetic pleasure derived from the abstractness, purity, simplicity, depth or orderliness of mathematics. Mathematicians may express this pleasure by describing mathematics (or, at least, some aspect of mathematics ...
Face validity. Face validity is the extent to which a test is subjectively viewed as covering the concept it purports to measure. It refers to the transparency or relevance of a test as it appears to test participants. [ 1][ 2] In other words, a test can be said to have face validity if it "looks like" it is going to measure what it is supposed ...
Figure–ground (perception) Figure–ground organization is a type of perceptual grouping that is a vital necessity for recognizing objects through vision. In Gestalt psychology it is known as identifying a figure from the back ground. For example, black words on a printed paper are seen as the "figure", and the white sheet as the "background ...
The goddess has been associated with sexuality, love, and fertility. [ 5][ 6][ 7] Xi Shi ( 西施 ), born 506 BC, was one of the Four Great Beauties of ancient China. [ 8] Physical attractiveness is the degree to which a person's physical features are considered aesthetically pleasing or beautiful. The term often implies sexual attractiveness ...
Content validity. In psychometrics, content validity (also known as logical validity) refers to the extent to which a measure represents all facets of a given construct. For example, a depression scale may lack content validity if it only assesses the affective dimension of depression but fails to take into account the behavioral dimension.
