In cognitive psychology, Brown–Peterson task (or Brown–Peterson procedure) refers to a cognitive exercise designed to test the limits of working memory duration. The task is named for two notable experiments published in the 1950s in which it was first documented, the first by John Brown [1] and the second by husband-and-wife team Lloyd and Margaret Peterson.
The Corsi block-tapping test is a psychological test that assesses visuo-spatial short term working memory. It involves mimicking a researcher as they tap a sequence of up to nine identical spatially separated blocks. The sequence starts out simple, usually using two blocks, but becomes more complex until the subject's performance suffers.
Short-term memory for learned associations has been studied using the match-to-sample task (and the related delayed match-to-sample task, and non-match to sample task).The basic procedure begins by presenting a subject with a stimulus (often a light of a particular color, or a visual pattern) that they will be required to remember, known as the 'sample'.
Ebbinghaus also collected data on his ability to memorize at different times of the day and under different conditions. His work later influenced G.E. Müller who continued the tradition of lists of items to conduct memory experiments on human subjects and using behavioural data to develop models of memory. [3]
Neither holds information for long, but short-term memory is a simple store, while working memory allows it to be manipulated. [17] Short-term memory is part of working memory, but is not the same thing. Working memory refers to structures and processes used for temporarily storing and manipulating information.
In particular, the Dynamic Tagging Theory makes use of statistical data taken from such experiments in formulating a phenomenological explanation of short-term memory. George A. Miller wrote a widely known paper describing the limitations of memory and the power of categories to improve recall, especially in short-term memory.
Short-term memory has limited capacity and is often referred to as "working-memory", however these are not the same. Working memory involves a different part of the brain and allows you to manipulate it after initial storage. The information that travels from sensory memory to short-term memory must pass through the Attention gateway. The ...
[8] [10] Time-related variables are commonly used in CHREST and its subsequent simulations, such as the main limiting factor of visual short-term memory being restricted. [ 4 ] [ 10 ] The algorithm takes into account the typical time spent when simulating a specific action, such as mentally calculating each position, and “increments the ...
