The liability-threshold model is a threshold model of categorical (usually binary) outcomes in which a large number of variables are summed to yield an overall 'liability' score; the observed outcome is determined by whether the latent score is smaller or larger than the threshold. The liability-threshold model is frequently employed in ...
Edwin Ray Guthrie (/ ˈ ɡ ʌ θ r i /; January 9, 1886 – April 23, 1959), a behavioral psychologist, began his career in mathematics and philosophy in 1917. He spent most of his career at the University of Washington, where he was a full-time professor and later became an emeritus professor in psychology.
Attenuation theory, also known as Treisman's attenuation model, is a theory of selective attention proposed by psychologist Anne Treisman that explains how the mind processes sensory input by weakening (attenuating) unattended stimuli rather than fully blocking them. [1]
In psychology, identification of giftedness is usually based on IQ scores. The threshold of IQ = 130 is defined by statistical rarity. By convention, the 5% of scores who fall more than two standard deviations from the mean (or more accurately 1.96) are considered atypical. [21]
Statistics [13] Information literacy [14] Writing studies [15] The theory has also been criticised. [16] The notion of threshold concept is related to the notion of bottleneck in the Decoding the Disciplines framework. It can be considered a special case of the latter. [17] [18]
Student development process models. Student development process models can be divided into abstract and practical. There are dozens of theories falling into these five families. Among the most known are: [7] Arthur W. Chickering's theory of identity development; William G. Perry's cognitive theory of student development
The point at which critical mass is achieved is sometimes referred to as a threshold within the threshold model of statistical modeling. The term "critical mass" is borrowed from nuclear physics, where it refers to the amount of a substance needed to sustain a chain reaction. Within social sciences, critical mass has its roots in sociology and ...
Merikle's work sought to shift the debate from indirect-without-direct effects determined by Holender to be the only way unconscious perception could be proved, to what he defined as objective (forced chance level) and subjective thresholds (a threshold of claimed awareness) as a means to distinguish stimuli presentation. He believed that the ...
