We provide a broad overview of our original investigation of working memory; how the multicomponent model followed from our use of a dissociative methodology; and our intention that it should be simple, robust, and applicable. We describe how subsequent development of the model has increased its scope, depth, and applications while at the same time retaining its core features. Comparisons with the growing number of alternative models suggest agreement on the basic phenomena to be explained and more similarities than differences.

Working memory is an active system responsible for the temporary maintenance and processing of information in the support of cognition and action. In keeping with this, a growing body of research has explored the close links between working memory and attention, and how these might be harnessed to impact performance and possibly improve working memory efficiency. This is theoretically and practically important, given that working memory is a central hub in complex cognition yet is extremely capacity- and resource-limited.

Background: The new severe acute respiratory syndrome coronavirus 2, SARS-Cov2, more commonly known as COVID-19 continues to be an ongoing cause of one of the most disruptive pandemics worldwide. UK universities comprise students who come from different backgrounds and cultures and the majority returned home or lived alone during the lockdown. This qualitative study aimed to compare the experiences of students from Black, Asian, and Minority Ethnic (BAME) backgrounds and White British students.

An increasingly popular method for investigating visuospatial working memory assumes stored features of objects such as color and orientation vary along continua subject to internal noise. It adapts the stimulus adjustment procedure from perceptual psychophysics to assess the precision with which stored features are represented in memory. This contrasts with methods using discrete, categorical measures of feature retention.

Research from a working memory perspective on the encoding and temporary maintenance of sequential instructions has established a consistent advantage for enacted over verbal recall. This is thought to reflect action planning for anticipated movements at the response phase. We describe five experiments investigating this, comparing verbal and enacted recall of a series of action-object pairings under different potentially disruptive concurrent task conditions, all requiring repetitive movements.
