Tsai Number-Joining Test Scores Correlated with College Students' Performance on Wais and Dat

Abstract

25 college seniors and graduate students took the WAIS and another group took the DAT ( ns, 28 to 34). Scores were correlated with performance on the Tsai Number-joining Test. Pearson correlations for Performance, Verbal and Full Scale WAIS IQs are .31, .00, and .13 respectively. Subtest correlations range from .35 (Digit Symbol) to .02 (Digit Span). For DAT, Tsai test performance has much higher rs with Spelling (.65), Verbal Reasoning (.61), Grammar (.47), and Abstract Reasoning (.36) than with Clerical Speed and Accuracy (.25), Numerical Ability (.23), Space Relations (.21), and Mechanical Reasoning (.08). Comparisons were made with findings of previous investigators. Relative potentiality of the Tsai Number-joining Test as an aptitude vs an intelligence test, besides being a research tool, is discussed.
