Results Results suggest a moderate correlation between WAIS-IV ldsf (M = 7.14, SD = 1.31) and TMB (M = 6.90, SD = 1.29) ldsf raw scores, r = 0.45, p > 0.01. A Pearson correlation was run on the TMB and WAIS-IV longest digit span forward (ldsf) and longest digit span backward (ldsb) raw scores of the same individuals. Demographic characteristics were as follows: Age (M = 28.5, SD = 11.2), education (M = 16.2, SD = 1.9), gender (60% Female), race (69.8% White). Undiagnosed adult volunteers (n = 105) took the WAIS-IV Digit Span and TMB Digit Span subtests. Method The data were chosen from a de-identified database. A peak-span model is proposed to integrate the findings into previous research on the word length effect.Ībstract Objective To see how strongly performance on a computerized visual digit span task correlates with non-computerized digit span subtests. These results suggest that a balanced distribution of two-syllable digits in a forward digit span tests should theoretically increase the test’s comparability and reduce language-related biases thus increasing the test’s parallel-form reliability. Results suggest that an elimination of two-syllable digits in a digit span test significantly reduced forward span test score (Cohen’s d = 0.36), but had no effect on backward span scores. The study examined the effect of amount of syllables on Norwegian digit span test scores by altering the prevalence of two-syllable digits using three conditions in a repeated measures design ( N = 54). It was hypothesized that this effect can be shown as a connection between the prevalence of digits with two syllables and digit span score. ![]() Although the relationship between digit verbal length and digit span has been investigated between languages, it has not been investigated within a language. The word length effect shows a connection between word length and working memory performance.
