kappa effect

the interaction between the perceived duration of a stimulus and the spatial extent of the stimulus. When a small visual stimulus and a large visual stimulus are both flashed for the same length of time, the duration of the large stimulus is perceived as longer than that of the small stimulus. An analogous effect has been described for tactile sensations.

survival analysis

survival analysis

a family of statistical methods used to model a variety of time-related outcomes. The simplest application of survival analysis involves estimating the amount of time until the occurrence of an event (e.g., death, illness, graduation, marriage) for a group of individuals, but the technique also may be applied to compare durations for two or more groups and to build multivariate models that explain variation in duration. Also called event history analysis.
