Figure 6. Comparison of the CASR memory and working memory analyses.

The possible 5-state alternation paths are shown again, but altered to demonstrate that the paths may be of differing lengths and that there may be many possible paths. A symmetry of the two memory systems is demonstrated by the complimentary way they depend on information from the beginning and end of episodes. A. In the case of CASR memory, observations in each possible episode are examined from the left end of the sequence. These observations correspond to paths out of the observation to be disambiguated. B. With working memory, observations are examined from the right end of the sequence, corresponding to paths leading into the observations to be disambiguated.
