Abstract
The hysteresis effect is a phenomenon common to human processing tasks where subjects respond to a linearly increasing then decreasing rate of information. A hysteresis curve results when the information presentation rate and the subject processing rate are plotted. One explanation for a performance decrement beyond the point of overload, which is an essential characteristic of the hysteresis effect, is that information enters short term memory (STM) faster than it is transmitted. In this study, the STM hypothesis was incorporated into a human processor model and the task was analysed by computer simulation. The simulation showed no performance decrement as a result of the STM hypothesis. However, a performance decrement was demonstrated when processing time varied with the presentation rate.
