本研究特別針對一份有時間限制的圖形認知能力測驗為目標,分別探索心理計量(分數、作答時間、α係數)及經驗歷程(電腦焦慮、電腦經驗背景、電腦喜好程度)的相等性。結果顯示紙筆版本的平均分數顯著高於電腦化版本的平均分數,且有顯著的學習與練習效果。此外無論版本,受試者的電腦焦慮程度、電腦經驗多寡及對電腦化測驗的喜好程度皆與測驗分數無顯著相關。但電腦經驗愈多或對電腦化測驗愈喜歡的受試者,在電腦化版本的作答時間則愈短。本研究建議對於速度或圖形的心理測驗而言,電腦化版本可能會產生分數不等性的問題,因此應該分別建立其常模及進行信效度的驗證。此外,由於國內學生多年習慣於紙筆測驗的作答方式,因此研究者也需留意電腦化測驗之樣本偏誤的可能性。
The purpose of this study is to investigate the equivalency of the computer-based and traditional paper-pencil versions of a timed pictorial ability test. The results showed that the mean score on the paper-pencil version was significantly higher than that on the computer-based version, although the test time of two versions did not make difference. Besides, Learning and practice effects were found in both test versions. In addition, computer anxiety, computer experience, and computer preference were not significantly related to the test scores of two versions. However, the users who had more computer experience or more preference toward computerized testing spent less time to respond the computer test. It was suggested that the score unequivalency between the computerized and paper-pencil versions might occur for a speed or pictorial psychological test. Therefore, if those tests were computerized, differential validity should be concerned and different norm should be provided. It was also suggested that the subjects for computerized testing might yield sample bias.
