SELF‐ASSESSMENTS OF FIVE TYPES OF TYPING ABILITY1
研究了156名高中生对五种打字材料的自我评估能力，发现直抄打字自我评估最能预测实际打字能力，且少数族裔学生的自我评估准确性较低。
The potential usefulness of self‐assessments of typing ability were examined from a personnel selection perspective. A sample of 156 “business ready”, Phoenix area high school students estimated their abilities to type each of the following types of materials in units of net words per minute: 1. straight copy 2. letters 3. revised manuscript 4. numbers 5. tables. The students then took the analogous portions of the Typing Test for Business , Self‐assessment of straight copy typing ability emerged as the best predictor of tested typing ability of all types. Because of the substantial number of minority students in the sample ( N = 69, 44.2%), differential prediction was studied. Self‐assessments of revised manuscript, numbers, and tables typing abilities were significantly higher for the majority group than for the minority group. Typing test performance was significantly higher for the majority group across straight copy, letters, revised manuscript, and tables subtests. Minority group members were generally less accurate in self‐assessment of their typing ability. Subgroup regression lines were compared by means of Potthoff's analysis, and subgroup differences in prediction of tested typing ability from self‐assessments of typing ability were found.
