Working memory has been one of the most intensively studied systems in cognitive psychology. The Cognitive Neuroscience of Working Memory brings together world class researchers from around the world to summarise our current knowledge of this field, and directions for future research.

Although external representations, such as sketches, are regarded as facilitating insight during creative synthesis and design tasks, previous empirical studies have provided conflicting evidence in support of this role. Here, we argue sketches are static representations that fail to fully externalise mental imagery processes involved during creative synthesis tasks. An experiment is reported in which participants manipulate simple alpha-numeric and geometric shapes into patterns depicting familiar objects or symbols. Trials were performed using either mental imagery alone, drawing manipulations in the (...) air with a finger, sketching manipulations on a piece of paper, or dynamically performing the manipulations on-screen using a graphics package. Results show the number of patterns correctly interpreted as recognisable objects was significantly higher in the dynamic support condition in comparison to all other conditions. Based on this finding, we argue that static forms of external support may be less effec.. (shrink)

Working-memory retention as activated long-term memory fails to capture orchestrated processing and storage, the hallmark of the concept of working memory. The event-related potential (ERP) data are compatible with working memory as a mental workspace that holds and manipulates information on line, which is distinct from long-term memory, and deals with the products of activated traces from stored knowledge.

Glenberg focuses on conceptualizations that change from moment to moment, yet he dismisses the concept of working memory (sect. 4.3), which offers an account of temporary storage and on-line cognition. This commentary questions whether Glenberg's account adequately caters for observations of consistent data patterns in temporary storage of verbal and visuospatial information in healthy adults and in brain-damaged patients with deficits in temporary retention.
