Historically, Digit Span has been regarded as a relatively poor indicator of general intellectual functioning (g). In fact, Wechsler (1958) contended that beyond an average level of Digit Span performance, there was little benefit to possessing a greater memory span. Although Wechsler’s position does not appear to have ever been tested empirically, it does appear to have become clinical lore. Consequently, the purpose of this investigation was to test Wechsler’s contention on the Wechsler Adult Intelligence Scale-Fourth Edition normative sample (N ⫽ 1,800 ages: 16 – 69). Based on linear and nonlinear contrast analyses of means, as well as linear and nonlinear bifactor model analyses, all 3 Digit Span indicators (LDSF, LDSB, and LDSS) were found to exhibit primarily linear associations with FSIQ/g. Thus, the commonly held position that Digit Span performance beyond an average level is not indicative of greater intellectual functioning was not supported. Keywords: memory span, Digit Span, general intelligence, working memory The results are discussed in light of the increasing evidence across multiple domains that memory span plays an important role in intellectual functioning. The association between memory span, as measured by Digit Span from the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV Wechsler, 2008a), and g. ![]() If Digit Span scores were observed to share a meaningful and largely linear association with g, then the relatively poor view of the Digit Span test within the clinical assessment community would need to be reconsidered. By contrast, if Digit Span scores were observed to share a nonlinear (quadratic and negative) association with g, then Wechsler’s position would be substantiated. Either position would be an important one to demonstrate empirically. From an applied clinical perspective, it was considered important to address this question, because Digit Span is one of the 10 core subtests within the Wechsler scales that are used to estimate an individual’s FSIQ. If Digit Span were observed to share a nonlinear association with g, as contended by Wechsler, then perhaps it would be appropriate to consider substituting it for another subtest, one that has a respectable association with g across the whole spectrum of ability. “Memory span for digits has been underrated as a psychometric test by most clinical psychologists.” -(Jensen, 1970, p. The assessment of individual differences in memory span has a long history (Blankenship, 1938 Dempster, 1981). ![]()
