In cognitive psychology, Brown–Peterson task (or Brown–Peterson procedure) refers to a cognitive exercise designed to test the limits of working memory duration.

Their results showed that the longer each student had to count backwards, the less well they were able to recall the trigram accurately. 1. After 3 seconds 80% of the trigrams were recalled correctly. 2. After 6 seconds this fell to 50%. 3. After 18 seconds less than 10% of the trigrams were recalled correctly.
Short-term memoryhas a limited duration (of about 18 seconds) when rehearsal is prevented. It is thought that this information is lost from short-term memory from trace decay. The results of the study also show the short-term memory is different from long-term memory in terms of duration. Thus supporting the multi-store model of memory. If a person...
In this study, the researchers used fixed timings for participants to count backwards from. They also eliminated noise and other factors that could have had an influence on memory. The research can therefore be said to have good control, using standardized procedures to make sure all participants experienced the same process. This means that the st...
The Brown-Peterson task is a cognitive psychology experiment that measures an individual’s ability to retain and recall information over a short period of time, specifically working memory. It is named after its creators, psychologists Lloyd R. Peterson and Margaret Jean Peterson.
Nov 21, 2023 · The Brown-Peterson task, also known as the Brown-Peterson distractor technique, is a memory exercise. This exercise requires participants to view several consonant trigrams (three...
The Brown-Peterson Procedure is a cognitive psychology task used to measure the decay of short-term memory (STM) over time. It investigates a participant’s ability to retain information in STM while preventing rehearsal through the use of distractor tasks.
May 12, 2014 · Brown-Peterson Task. Estimated time to complete lab: 20 minutes. Background. In the 1932, John McGeoch wrote an extremely influential critique of theories of forgetting, and for the next 25 years or so, no researcher viewed decay as a viable explanation of forgetting. Instead, memory loss was considered to be the result of interference.
The thesis of Brown is that memory traces decay over a brief time period, until some threshold is reached and the memory becomes unreliable. Brown argues that this theory offers a simple explanation of both why we forget and why we have a capacity limit in memory.
