Comments on the article A temporal ratio model of memory by Brown, Neath, and Chater. SIMPLE (G. D. A. Brown, I. Neath, & N. Chater, 2007) attempts to explain data from serial recall and free recall in the same theoretical framework. While it can fit the free-recall serial-position curves that are the cornerstone of the 2-store buffer model, it…

Three hypotheses of forgetting from immediate memory were tested: time-based decay, decreasing temporal distinctiveness, and interference. The hypotheses were represented by 3 models of serial recall: the primacy model, the SIMPLE (scale-independent memory, perception, and learning) model, and the SOB (serial order in a box) model, respectively.…

How does the brain carry out working memory storage, categorization, and voluntary performance of event sequences? The LIST PARSE neural model proposes an answer that unifies the explanation of cognitive, neurophysiological, and anatomical data. It quantitatively simulates human cognitive data about immediate serial recall and free recall, and…

Reply to comments on an article "Issues With the SIMPLE Model: Comment on Brown, Neath, and Chater" (2007) by Bennet Murdock on the current authors' original article "A temporal ratio model of memory" by Brown, Neath, and Chater. Does a single mechanism underpin serial and free recall? B. Murdock (2008) argued against the claim, embodied in the…

This article presents an extended version of the convolution-correlation memory model TODAM (theory of distributed associative memory) that eliminates some inadequacies of previous versions and provides a unified treatment of item, associative, and serial-order information. TODAM2 extends the chunking model to provide a general model for episodic…

There is general agreement that the effect of frequency on lexical access time is roughly logarithmic, although little attention has been given to the reason for this. The authors argue that models of lexical access that incorporate a frequency-ordered serial comparison or verification procedure provide an account of this effect and predict that…

A theory of practice in high-proficiency skills such as speech production is proposed, involving activation of a hierarchy of nodes in serial order within an output system of behavior. Increased flexibility with practice, response mechanism transfer in skills, motor equivalence, automaticity, and speed-accuracy trade-off are discussed. (Author/CM)

An associative model of serial learning is described based on the assumption that the effective stimulus for a serial-list item is generated by adaptation-level coding of the item's ordinal position. How the model can generate predictions of aspects of serial-learning data is illustrated. (SLD)

The notion of strength is defined in several alternative ways for chains of associations connected in series and in parallel. Network strength theory is extended to handle retrieval dynamics for a network of associations, in a manner that permits various degrees of serial versus parallel manner that permits various degrees of serial versus…

Ratcliff's theory of memory retrieval which posits parallel processing and Sternberg's serial processing explanation of memory scanning are reviewed and contrasted. Discrepancy between the two theories may arise because they focus on different aspects of the data. If scanning without comparisons takes place, the two views may be reconciled.…
