Trace susceptibility theory

A new theory for the dynamics of trace susceptibility to storage loss is developed and tested. According to the trace susceptibility theory, storage loss occurs when a critical feature for the support of recall is no longer bound to the other features of the trace. The storage loss occurs because of the retroactive influence of other traces, and the storage retention function is precisely characterized by an underlying Weibull distribution. Predictions of the trace susceptibility theory were tested against predictions of a multistore model. The results support the trace susceptibility theory. Finally, the relation between the trace susceptibility theory and proactive interference effects was developed.
