In psychology and neuroscience, memory span is the longest list of items that a person can repeat back in correct order immediately after presentation on 50% of all trials. Items may include words, numbers, or letters. The task is known as digit span when numbers are used. Memory span is a common measure of working memory and short-term memory.
23 Μαρ 2017 · The emergence of theoretical steps based on strategies, organization, and other cognitive constructs seemingly going beyond the fundamental behavioral event of response to stimulus (e.g., Dixon & Horton, 1968) made simple span, at best, a low-level psychological event.
The term memory span refers to the maximum length of a sequence of items that can be reproduced from memory following a single presentation. Scientists have been interested in memory span since the publication of the first important study of memory, nineteenth-century German experimental psychologist Hermann Ebbinghaus 's monograph in 1885.
31 Δεκ 2021 · researchers in the psychology of memory has led to a better understanding of how human memory works, and this paves the way for more effective measures of memory capacity.
Memory span is defined as the sequence length at which recall is correct half the time and is found to be between six and seven for digits, and even less for items such as unrelated words (Crannell & Parrish, 1957). Similar capacity constraints are evident in nonverbal tasks requiring the recall of spatial sequences or the locations or visual ...
Working memory (WM) span tasks—and in particular, counting span, operation span, and reading span tasks—are widely used measures of WM capacity. Despite their popularity, however, there has never been a comprehensive analysis of the merits of WM span tasks as measurement tools.
The purpose of this article is to present a behavioral theory of performance in the simple (classic) memory span experiment. This experiment has been used to investigate hypothetical mental and neurological processes and intelligent function, but behavioral span theory takes the standpoint of event-based constructs.
