Quantifying qualitative features of Block Design performance among healthy older adults.
نویسندگان
چکیده
Block Design tasks are neuropsychologically valuable, but standard scoring sacrifices potentially useful information that could elucidate the cognitive processes underlying performance failures. Qualitative indices that were proposed in the WAIS-R-NI [Kaplan, E., Fein, D., Morris, R., & Delis, D. (1991). The WAIS-R as a neuropsychological instrument [Manual]. San Antonio, TX: Psychological Corporation] should help to remedy this situation but have received little research attention. We present WAIS-R Block Design data for 177 healthy older adults (aged 50-90) incorporating several qualitative measures, outlining normative ranges and examining age differences. Proportional scoring, counts of single-block placement and rotation errors, counts of parameter-violating errors such as breaking configuration, and availability of implicit grid information all offer potentially valuable supplementary data that can enrich clinical interpretation of Block Design protocols.
