![]() In light of these findings, recommendations are provided to foster, in the future, consistency across aphasia studies and confidence in STM/WM tests as assessment and treatment outcome measures. Studies using these tests inconsistently documented demographic and aphasia variables essential to interpreting STM/WM test outcomes. Standardisation samples to elicit normative data were often small, and most measures exhibited poor validity and reliability properties. Exploratory factor analysis in a subset of 357 participants identified a five-factor structure: (1) attentional capacity (Multiple Object Tracking, Visual Working Memory, Digit Symbol Coding, Spatial Span), (2) search (Visual Search, TMT-A, TMT-B, Letter Cancellation) (3) Digit Span (4) Arithmetic and (5) Sustained Attention (GradCPT). In this test, participants were presented with a series of numbers that. In 1956, George Miller asserted that the span of immediate memory and absolute judgment were both limited to around 7 7 7 7 pieces of information. Results revealed that a very limited number of standardised tests, in the verbal and non-verbal domains, had robust psychometric properties. This working memory measure was administered via. Accordingly, the goals of this systematic review were: (1) to identify standardised tests of STM and WM utilised in the aphasia literature, (2) to evaluate critically the psychometric strength of these tests, and (3) to appraise critically the quality of the investigations utilising these tests. To date, however, no previous systematic review has focused on aphasia. Increasing interest in assessing STM and WM in aphasia research and clinical practice as well as a growing evidence base of STM/WM treatments for aphasia warrant an understanding of the range of standardised STM/WM measures that have been utilised in aphasia.
