Study on serial position curve phenomena

Two storage mechanisms in free recall.

As long as the recall process is competitive, recent items will win out, so a recency effect is observed. Context-based models predict recency in free recall because the temporal context at the end of the list is used as a retrieval cue, and it most closely matches the contexts associated with end of list items.

This recency effect exists even when the list is lengthened to 40 words. This is a preview of subscription content, log in to check access.

As long as the recall process is competitive, recent items will win out, so a recency effect is observed. Context-based models predict recency in free recall because the temporal context at the end of the list is used as a retrieval cue, and it most closely matches the contexts associated with end of list items. Results He found that the probability of recalling any word depended on its position in the list its serial position. Inconsistency discounting Participants would disregard information that was not consistent with previous items presented to them. The serial position effect consists of two phenomena viz. The reason for recency effect is also explained in terms of the the retroactive interference during encoding, i. New York: Academic Press. As such, dual-store models successfully account for both the recency effect in immediate recall tasks, and the attenuation of such an effect in the delayed free recall task. The existence of this long-term recency effect thus raises the possibility that immediate and long-term recency effects share a common mechanism. In the current set of studies, we sought to exert the methodological control of presenting lists of experimenter-controlled, unrelated words from established stimulus sets over the extended inter-stimulus intervals of 1 word every hour. In this method the subject is given a list of various items words of the same length that should be remembered. The 1st, that low frequencies result in poor recognition memory, hence poorer recency discrimination, was discounted in Exp I, which still found sizable frequency effects on relative recency judgments even when considering only recognized items. Still greater inter-presentation intervals were used by Glenberg et al. Keywords: Smartphone, Free recall, Serial recall, Temporal contiguity effects, Time-scale invariance, Recognition memory Introduction The presentation and testing of word lists has been a fundamental source of empirical data in the study of the psychology of memory e.

Conclusion Murdock suggested that words early in the list were put into long term memory primacy effect because the person has time to rehearse each word acoustically.

The standard methodology is to calculate the Conditionalized Response Probabilities CRPs of making transitions of different lags.

This occurs despite the reduction in opportunity to co-rehearse words, since the STS must be used to carry out the distractor task in between each list item. Contemporary models of temporal distinctiveness assume that similar memory mechanisms operate on episodic memory over very different timescales, a hypothesis actively pursued by many researchers e.
