• 中文摘要： 本研究主要探討非診斷資訊對判斷績效可能造成不利的稀釋作用。研究中採用判斷個案設計的方式，配合重複測試的作法，以探討判斷個案中加入非診斷資訊，對判斷者的判斷績效造成的可能影響。研究結果發現，在判斷個案中的診斷性資訊，加入非診斷資訊之後，會對判斷行為造成不利的稀釋效果，並降低判斷的正確性；而且，當非診斷性資訊線索持續的增加時，這種不利的稀釋效果，亦將出現持續增強的現象。此一結果顯示，非診斷資訊線索的確會對判斷績效及決策效能產生不利的影響。
• 英文摘要： This paper explores the influence of nondiagnosis information on the judgement performance.Research were designed in judgemental cases. In test-retest process, two other nondiagorrostic cues wereadded to the original judgemental cases, to examine its impact of nondiagnosis information on judgementaccuracy. The findings demostrate that nondiagonostic information will generate unfavorable dilutioneffect in judgement process and decreased indiviaual's judgement accuracy; and furthermore, as non-diagonostic cues incresed in judgemental process, the negative impacts from its nondiagonostic propertyagainst judgement accuracy are also increased. The findings also imply that diagnostic information selec-tion in research process need to be cautious to preventing degeneration of effectiveness of expert judgementand its decision effectiveness.
