The MaxDiff is a long-established theory in mathematical psychology with very specific assumptions about how people make choices: [1] it assumes that respondents evaluate all possible pairs of items within the displayed set and choose the pair that reflects the maximum difference in preference or importance.
Laboratory of Comparative Human Cognition (LCHC) [1] is a social science laboratory located at the University of California, San Diego (UCSD) since 1978. Scholars at LCHC pursue research focused on understanding the complex relationship between cognition and culture in individual and social development.
In psychophysics, sensory threshold is the weakest stimulus that an organism can sense.Unless otherwise indicated, it is usually defined as the weakest stimulus that can be detected half the time, for example, as indicated by a point on a probability curve. [1]
In general, any infinite series is the limit of its partial sums. For example, an analytic function is the limit of its Taylor series, within its radius of convergence. = =. This is known as the harmonic series. [6]
Hal Pashler is Distinguished Professor of Psychology at University of California, San Diego.An experimental psychologist and cognitive scientist, Pashler is best known for his studies of human attentional limitations (his analysis of the Psychological refractory period effect concluded that the brain has discrete "processing bottlenecks" associated with specific types of cognitive operations).
In statistics, asymptotic theory, or large sample theory, is a framework for assessing properties of estimators and statistical tests. Within this framework, it is often assumed that the sample size n may grow indefinitely; the properties of estimators and tests are then evaluated under the limit of n → ∞. In practice, a limit evaluation is ...
The maximum likelihood method has many advantages in that it allows researchers to compute of a wide range of indexes of the goodness of fit of the model, it allows researchers to test the statistical significance of factor loadings, calculate correlations among factors and compute confidence intervals for these parameters.

Boroditsky is professor of cognitive science at the University of California, San Diego (UCSD). She studies language and cognition, focusing on interactions between language, cognition, and perception. Her research combines insights and methods from linguistics, psychology, neuroscience, and anthropology.
