"There are a number of drive theories. The Drive Reduction Theory grows out of the concept that we have certain biological needs, such as hunger. As time passes the strength of the drive increases as it is not satisfied. Then as we satisfy that drive by fulfilling its desire, such as eating, the drive's strength is reduced. It is based on the theories of Freud and the idea of feedback control systems, such as a thermostat."
Does anyone think this can be applied to evacuations: as time progresses, a persons drive to escape the building increases? If so, what is the resulting behaviour we might expect to observe from it?
Also, are there any reasons when a persons drive might decrease within an evacuation?
