Working Memory: Evaluates the capability to hold and manipulate data in thoughts for quick periods. Widespread tasks contain digit span and letter-quantity sequencing.
Processing Speed: Assesses how speedily and accurately a single can execute very simple or routine cognitive tasks. Tasks generally include things like symbol search and coding.
