weapons effect

increased hostility or a heightened inclination to aggression produced by the mere sight of a weapon. If provoked, individuals who have previously been shown a weapon will behave more aggressively than will those who have not. Subsequent research has indicated that this aggressive behavior is primed by the sight or suggestion of weapons (see priming) and that any other object associated with aggression can have the same effect. [identified in 1967 by U.S. psychologists Leonard Berkowitz (1926–  ) and Anthony LePage]

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.
