Direction, Velocity, Merging Probabilities and Shape Descriptors for Crowd Behavior Analysis

open access: yesIEEE Access, 2019
Descriptors are important for quantifying crowd behavior. The existing descriptors generally provide information about crowd density, i.e., number of people/objects present in a defined spatial area.

Resistance to change of responding maintained by unsignaled delays to reinforcement: a response-bout analysis.

open access: yes, 2006
Previous experiments have shown that unsignaled delayed reinforcement decreases response rates and resistance to change. However, the effects of different delays to reinforcement on underlying response structure have not been investigated in conjunction ...
