Working-memory tasks differ by emphasizing storage versus active manipulation

Evidence

Working memory (WM) has no universally-accepted definition. One characterisation posits that WM refers to the ability to simultaneously store and process task-relevant information (Daneman and Carpenter 1980 ). WM tasks may emphasize either storage or processing. Storage-heavy tasks, such as Digit Span and Letter-Number Sequencing (Wechsler 1997 ), require participants to repeat back material either unchanged or slightly changed. Processing-heavy tasks, such as the Reading Span task (Daneman and Carpenter 1980 ), require a response that differs considerably from the original material and is only achieved by substantial mental manipulation. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1229
