![]() One possible reason DSF and DSB (and DSS) test scores continue to be summed together into a subscale is that Reynolds’ (1997) line of research has not been extended. Arguably, however, Reynolds’ (1997) concerns do not appear to have been specifically addressed in the psychological assessment literature. The most recent editions of the Wechsler scales (Wechsler Adult Intelligence Scale–Fourth edition, Wechsler, 2008 The Wechsler Intelligence Scale for Children–Fifth edition, Wechsler, 2014) include a third serial recall test, Digit Span Sequencing (DSS), into the summation of the Digit Span subscale. However, several years ago, Reynolds (1997) contended that DSF and DSB should not be combined for clinical analysis, because DSF and DSB measured two memory span dimensions that were insufficiently representative of a common dimension. In clinical practice, the use of composite scores derived from the sum of DSF and DSB performance remains popular today (e.g., Glassmire, Ross, Kinney, & Nitch, 2016). Finally, we offer suggestions for improvement to achieve higher levels of Digit Span subscale score reliability.ĭigit Span Forward (DSF) and Digit Span Backward (DSB) have a long history in the assessment of intelligence ( Blankenship, 1938 Dempster, 1981 Gignac, 2015). Instead, interpretations should probably be restricted to the Digit Span Forward, Digit Span Backward, and Digit Span Sequencing test scores. In light of the results, clinicians are cautioned against interpreting Digit Span subscale scores. ![]() Based on omega hierarchical, we estimated the internal consistency reliability associated with the Digit Span subscale scores at. Next, we simulated item-level Digit Span subscale data to correspond very closely to the Wechsler Adult Intelligence Scale–fourth edition normative sample. With accessible examples, we demonstrate that stratified coefficient alpha can deviate substantially from a model-based internal consistency reliability that represents an underlying dimension, that is, omega hierarchical. 93, based on a coefficient known as stratified coefficient alpha. The Digit Span subscale (Digit Span Forward, Backward, and Sequencing combined composite) internal inconsistency reliability has been reported at. As long as students are covertly translating from a signed into a spoken language, teachers need to take into account students' limited memory span for signs.All subjects Allied Health Cardiology & Cardiovascular Medicine Dentistry Emergency Medicine & Critical Care Endocrinology & Metabolism Environmental Science General Medicine Geriatrics Infectious Diseases Medico-legal Neurology Nursing Nutrition Obstetrics & Gynecology Oncology Orthopaedics & Sports Medicine Otolaryngology Palliative Medicine & Chronic Care Pediatrics Pharmacology & Toxicology Psychiatry & Psychology Public Health Pulmonary & Respiratory Medicine Radiology Research Methods & Evaluation Rheumatology Surgery Tropical Medicine Veterinary Medicine Cell Biology Clinical Biochemistry Environmental Science Life Sciences Neuroscience Pharmacology & Toxicology Biomedical Engineering Engineering & Computing Environmental Engineering Materials Science Anthropology & Archaeology Communication & Media Studies Criminology & Criminal Justice Cultural Studies Economics & Development Education Environmental Studies Ethnic Studies Family Studies Gender Studies Geography Gerontology & Aging Group Studies History Information Science Interpersonal Violence Language & Linguistics Law Management & Organization Studies Marketing & Hospitality Music Peace Studies & Conflict Resolution Philosophy Politics & International Relations Psychoanalysis Psychology & Counseling Public Administration Regional Studies Religion Research Methods & Evaluation Science & Society Studies Social Work & Social Policy Sociology Special Education Urban Studies & Planning BROWSE JOURNALS Second, large individual differences in memory span for signs imply that teachers who require students to recall or translate signed discourse must take care to avoid a bias favoring students with a longer memory span. First, a short memory span for signs is evidence that signs are more complex than digits or words, possessing more features that need to be stored in short-term memory. ![]() The correlation between digits forward and signs (r = 0.419) was significant. Memory span for signs was significantly shorter than memory span for digits forward (6.94) and the mean reported elsewhere for words (5.5). The standard deviation of their memory span for signs was 1.11. The mean number of signs recalled by these hearing subjects was 4.44, slightly less than the mean of 4.9 previously reported for deaf subjects. Thirty-six hearing college students with approximately one semester experience in a beginning course in American Sign Language were tested for their memory span for signs and for digits forward and backward. ![]()
