Extinction-Induced Variability in Human Behavior

Of Behavior Extinction - Induced Aggression

Pigeons were conditioned to peck a response key under a procedure that alternated periods of food reinforcement with periods of extinction. The pigeons attacked a nearby pigeon at the onset of extinction. Some also attacked a stuffed model of a pigeon. The duration of attack was an inverse function of the time since the last food reinforcement and a direct function of the number of reinforcemen...

Stability and variability in extinction.

Some studies have found that extinction leaves response structures unaltered; others have found that response variability is increased. Responding by Long-Evans rats was extinguished after 3 schedules. In one, reinforcement depended on repetitions of a particular response sequence across 3 operanda. In another, sequences were reinforced only if they varied. In the third, reinforcement was yoked...

Vortex-induced Extinction Behavior in Methanol Gaseous Flames: a Comparison with Quasi-steady Extinction

Using a combination of HCHO planar laser-induced fluorescence and laser Doppler velocimetry measurements, the extinction behavior of methanol counterflow diffusion flames was examined experimentally under conditions in which the extinction was brought about by a vortex generated on the oxidizer side. Comparisons were made with quasi-steady extinction results for the same flames. It was found th...

Variability in Human Behavior Modeling for Military Simulations

Capturing and encoding human variability is an increasingly important issue in human behavior models (HBMs) for military simulations. In this paper, we define variability, describe its importance in several military simulation applications, examine the sources of variability in human behavior, and outline an approach to variability that will allow us to explore approaches to low-cost, realistic...
