Abstract: The 2×3×2 between subjects experiment examined the effects of extremity shifts, heuristics and social desirability on job information completeness. The completeness is cooperatively defined as the sum of all job information cross sets by any two providers. The MANOVA results indicated that: a) The extent of extremity shifts had effects on job information completeness. Extremity shifts lead to the incomplete job information under the condition of high social desirability, while under the condition of low social desirability extremity shifts had no effects on job information completeness; b) Heuristics led to the incomplete job information. As being motivated and provided with the typical job information, the participants will engage in systematic processing which makes the job information more complete; c) Social desirability is the moderator of extremity shifts job information completeness and heuristics job information completeness relationships.

Key words: job information completeness, extremity shifts, heuristics, social desirability

摘要： 研究通过2×3×2组间实验设计，探讨极端性转移、启发式和社会称许性对职务信息完整性的影响。多因素方差分析结果表明：a) 极端性转移对职务信息完整性的影响取决于极端性转移程度，高社会称许性条件下极端性转移导致职务信息不完整；b) 启发式策略导致不完整的职务信息，激发内部动机的同时提供典型职务信息，可促使被试进行系统化加工；c) 社会称许性是极端性转移和启发式与职务信息完整性关系的调节变量。
