摘要

A. BACKGROUND AND PROCEDUREnTwo experiments were conducted to determine the effects of including extraneous numerical information in arithmetic rea¬soning items.nB. RESULTS AND CONCLUSIONSn1. The subtests containing extraneous information tended to be less homogeneous (i.e., to have smaller variances, Kuder Richardson reliabilities and smaller item-test correlation coef¬ficients) than the subtests composed of the same items without extraneous information.n2. In four out of five comparisons the extraneous informa¬tion subtests correlated less highly with a test of verbal ability (the Navy GCT Test) than did their counterpart subtests not containing extraneous information.n3. The findings of this research do not support the inclu¬sion of extraneous information in arithmetic reasoning items if a relatively pure and homogeneous measure of arithmetic reasoning is desired, as is the case in the Navy Arithmetic Test.
