Īmnesiacs with poor ability to form permanent long-term memories do not show a primacy effect, but do show a recency effect if recall comes immediately after study. Additionally, if recall comes immediately after the test, the recency effect is consistent regardless of the length of the studied list, or presentation rate. Intervening tasks involve working memory, as the distractor activity, if exceeding 15 to 30 seconds in duration, can cancel out the recency effect. ![]() The recency effect is reduced when an interfering task is given. An additional explanation for the recency effect is related to temporal context: if tested immediately after rehearsal, the current temporal context can serve as a retrieval cue, which would predict more recent items to have a higher likelihood of recall than items that were studied in a different temporal context (earlier in the list). Items that benefit from neither (the middle items) are recalled most poorly. One theorised reason for the recency effect is that these items are still present in working memory when recall is solicited. Longer presentation lists have been found to reduce the primacy effect. (The first list item can be rehearsed by itself the second must be rehearsed along with the first, the third along with the first and second, and so on.) The primacy effect is reduced when items are presented quickly and is enhanced when presented slowly (factors that reduce and enhance processing of each item and thus permanent storage). One suggested reason for the primacy effect is that the initial items presented are most effectively stored in long-term memory because of the greater amount of processing devoted to them. Corwin Press.Tendency of a person to recall the first and last items in a series best, and the middle items worst Differentiated Instructional Strategies for the Block Schedule. Springer International Publishing 2014:133-147. Temporal development of quality of experience. Weiss B, Guse D, Möller S, Raake A, Borowiak A, Reiter U. ![]() Serial position, output order, and list length effects for words presented on smartphones over very long intervals. Working memory underpins cognitive development, learning, and education. Harvard University: The Derek Bok Center for Teaching and Learning. Replication and analysis of Ebbinghaus' forgetting curve. Research has found that if the distracting task takes longer than 15 to 30 seconds, it will eliminate recency effects when trying to recall the original information. ![]() ![]() Intervening tasks: Interference can occur if another task or information is presented after the first task.Time: If a long period of time elapses between the presentation and rehearsal of the information and recall, the recency effect is dramatically reduced or even eliminated altogether.Processing: How you attend to and process the information as it is presented can also affect how it is recalled.A very long list of terms, on the other hand, would be much more likely to produce recency effects. If you were presented a very short list of words, for instance, you might find it easy to recall all the items, essentially eliminating the recency effect. The length of the information presented and how it is presented can influence the recency effect. Task factors: This refers to the task itself as well as how the information is processed.
