A Distributed Representation of Remembered Time
Abstract
The overarching objective of the proposed research was to develop an extension of the temporal context model to enable the description of a broad variety of phenomena across various subfields of cognitive psychology by integrating a representation of the time at which stimuli were experienced. This was accomplished. We published a paper in Neural Computation that describes such a model and applied it to problems in episodic memory, timing and classical conditioning. A more detailed version of this model, described in a paper revised for Psychological Review, extends it to a wider range of phenomena by introducing a translation operator allowing for the construction of trajectories of predicted future states, and jumping-back-in-time to allow for an account of contiguity effects in episodic memory. In that paper we applied the model to problems from episodic memory, working memory, as well as second-order conditioning problems from trace conditioning. We met the near-term goals of generating simulation code for the model of timing, with three different approaches to simulating the equations implemented in the R program language.
