B. B. Murdock and M. I. Kahana (1993a) presenied a continuous memorv version of the lheory of distributed associative memory tTODAM) model: they claimed that this model predicts list- strength and lisl-length findings. including those reported by R. Ratcliff. S. E. Clark, and R. M. Shiffrin (l990) and K. Murnane and R. M. Shiffrin (l991a). This model is quite similar to one discussed by R. M. Shiffrin, R. Ratcliff, and S. Clark (l990). who rejected the model on the basis of its inability to predia both an absent or negative list-strength effect (when ssrength is varied by repetitions) and a present list-length effect. In this commem we elaborate the earlier discussion and demonstrate that the version of TODAM proposed by B. B. Murdock and M. J. Kahana (1993a) indeed fails for this reason. we show this first for a somewhat simpiified version or the model for which denvations are obvious and then in a simulation of the complete version using the parameter values suggested by B. B. Murdock and M. J. Kahana (1993a).
