    Abstract:
    The Five-point Test (Regard, Strauss, & Knapp, 1982) was introduced for the measurement of figural fluency as part of the examination of executive functions. Until now, no differentiated norms exist. We present normative data for adults aged 18-80 (n = 280) for the number of unique designs (productivity), the percent of perseverations (flexibility), the percent of rotated (strategic) designs, and the number of rule breakings. As age and education were correlated with test performance, norms were stratified by these two variables. Test-retest reliability and inter-rater reliability were calculated. Moreover, convergent and divergent validity as well as factorial validity were assessed through intercorrelations and correlations with other neuropsychological tests. All together, the Five-point Test proved to be reliable and valid.
