'''Serial memory processing''' is the act of attending to and processing one item at a time. This is usually contrasted against parallel memory processing, which is the act of attending to and processing all items simultaneously.

In short-term memory tasks, participants are given a set of items (e.g. letters, digits) one at a time and then, after varying periods of delay, are asked for recall of the items. As well, participants could be asked whether a specific target item was present in their original set.<ref name=Townsend>Townsend, J. & Fific, M. (2004).

===''Associated Models''===

- [[ACT-R]] is Adaptive Control of Thought-Rational. This model help to hierarchically organize serial memory. In this model, declarative memory works to encode the position of items while the production memory works to organize recall of items. This is a limited-capacity model, where there is a limited amount of activation available. This theorizes that longer memory sets lead to longer recall because the amount of activation available is divided among more items. The ACT-R models the serial position error <ref name=Naire /> and the independent acoustic errors <ref name = Bjork /> near perfectly. <ref name=Anderson />

- Sternberg's (1969) model of item recognition. In this model, item recognition follows several steps. First the test stimulus is presented and then the stimulus is encoded. Next, serial comparisons are completed (these are affected by the size of the memory set) and a binary decision is made on each comparison (e.g. positive, negative). Finally, a response is organized and expressed. <ref name = Sternbergg />.

-stimuli confusability can affect item recognition. Auditory confusability in the memory set increased encoding time and visual confusability in memory set increased comparison time <ref name=Connor />.
