Interference-adjusted power learning curve model with forgetting

Forgetting: Inhibition or Interference?

Short-term forgetting without interference.

In the 1st reported experiment, we demonstrate that auditory memory is robust over extended retention intervals (RIs) when listeners compare the timbre of complex tones, even when active or verbal rehearsal is difficult or impossible. Thus, our tones have an abstract timbre that resists verbal labeling, they differ across trials so that no "standard" comparison stimulus is built up, and the spe...

A Forgetting Model for Paired-Associate Learning

This paper presents a Markov model for paired-associate learning which is based on conclusion drawn from experimental studies of short-term memory. Learning of paired-associates is considered as a decrease in the probability of forgetting an association between trials. The ability of the model to account for experimental results is demonstrated by considering data from two experiments involving...

Interference-Based Forgetting 1 Interference-Based Forgetting in Verbal Short-Term Memory

This article presents four experiments that tested predictions of SOB (Serial Order in a Box), an interference-based theory of short-term memory. Central to SOB is the concept of noveltysensitive encoding, which holds that items are encoded to the extent that they differ from alreadyencoded information. On the additional assumption that distractors are encoded into memory in the same manner as ...

Power-law forgetting in synapses with metaplasticity

The idea of using metaplastic synapses to incorporate the separate storage of longand short-term memories via an array of hidden states was put forward in the cascade model of Fusi et al. In this paper, we devise and investigate two models of a metaplastic synapse based on these general principles. The main difference between the two models lies in their available mechanisms of decay, when a co...
