Working memory WM refers to the human capacity to encode, store, manipulate, and recall information. A proper understanding of WM therefore provides essential insights into human cognition. This chapter reviews available research concerning the impact of deafness and sign language use on WM, much of which comes from the study of a single subcomponent of WM termed short-term memory STM.

Working Memory From the Psychological and Neurosciences Perspectives: A Review
Since the concept of working memory was introduced over 50 years ago, different schools of thought have offered different definitions for working memory based on the various cognitive domains that it encompasses. The general consensus regarding working memory supports the idea that working memory is extensively involved in goal-directed behaviors in which information must be retained and manipulated to ensure successful task execution. Before the emergence of other competing models, the concept of working memory was described by the multicomponent working memory model proposed by Baddeley and Hitch. From the neuroscience perspective, it has been established that working memory activates the fronto-parietal brain regions, including the prefrontal, cingulate, and parietal cortices. Recent studies have subsequently implicated the roles of subcortical regions such as the midbrain and cerebellum in working memory.
The case for sensorimotor coding in working memory
Phyllis Kittler, Sharon J. Krinsky-McHale, Darlynne A. Am J Ment Retard 1 November ; 6 : — Semantic and phonological loop effects on verbal working memory were examined among middle-age adults with Down syndrome and those with unspecified mental retardation in the context of Baddeley's working memory model. Recall was poorer for phonologically similar, semantically similar, and long words compared to recall of dissimilar short words. Compared to their peers, participants with Down syndrome had poorer recall in all categories except phonologically similar words.

Baddeley's model of working memory is a model of human memory proposed by Alan Baddeley and Graham Hitch in , in an attempt to present a more accurate model of primary memory often referred to as short-term memory. Working memory splits primary memory into multiple components, rather than considering it to be a single, unified construct. This model is later expanded upon by Baddeley and other co-workers to add a fourth component, and has become the dominant view in the field of working memory. However, alternative models are developing, providing a different perspective on the working memory system. The phonological loop stores verbal content, whereas the visuo-spatial sketchpad caters to visuo-spatial data. Both the slave systems only function as short-term storage centers.
Working memory capacity in L2 processing
To widen explanations of memory, Baddeley and Hitch proposed their working memory model WMM offering an interacting link between sensory storages and long-term memory. In the following, these WMM-subsystems will be shortly described to then present and discuss evidence for each subsystem. Finally, the overall model will be evaluated, and practical applications presented.
In this paper, we review the current state of the second language L2 processing literature and report data suggesting that this subfield should now turn its attention to working memory capacity as an important factor modulating the possibility of near -native-like L2 processing.

However, difficulties with the model of verbal working memory in particular have led investigators to develop alternative models that avoid appealing either to sensory coding or to motoric coding, or to both. This paper examines the evidence for sensorimotor coding in working memory, including evidence from neuropsychology and from sign language research, as well as from standard working memory paradigms, and concludes that only a sensorimotor model can accommodate the broad range of effects that characterize verbal working memory. In addition, several findings that have been considered to speak against sensorimotor involvement are reexamined and are argued to be in fact compatible with sensorimotor coding.

By Dr. Saul McLeod , updated However, as a result of this research, it became apparent that there were a number of problems with their ideas concerning the characteristics of short-term memory. According to the Multi-Store Model , STM holds limited amounts of information for short periods of time with relatively little processing. It is a unitary system.
Информация уходит. - Вторжение по всем секторам. Сьюзан двигалась как во сне. Подойдя к компьютеру Джаббы, она подняла глаза и увидела своего любимого человека. Его голос гремел: - Три. Разница между 238 и 235 - три. Все подняли головы.

Сьюзан решительно шагнула во тьму. ГЛАВА 87 Веспа выехала в тихий переулок Каретерра-де-Хуелва. Еще только начинало светать, но движение уже было довольно оживленным: молодые жители Севильи возвращались после ночных пляжных развлечений. Резко просигналив, пронесся мимо мини-автобус, до отказа забитый подростками.
Чего только нет под солнцем. - Это был девиз туристского бюро Севильи. - Она назвала вам свое имя. - Нет.
Его аналитический ум искал выход из создавшегося положения. Сознание нехотя подтверждало то, о чем говорили чувства. Оставался только один выход, одно решение. Он бросил взгляд на клавиатуру и начал печатать, даже не повернув к себе монитор.
Танкадо использовал наживку для дурачков… и АНБ ее проглотило. Сверху раздался душераздирающий крик Стратмора. ГЛАВА 86 Когда Сьюзан, едва переводя дыхание, появилась в дверях кабинета коммандера, тот сидел за своим столом, сгорбившись и низко опустив голову, и в свете монитора она увидела капельки пота у него на лбу.
