中文摘要：

基于智力差异的人格分化假设认为,高智力者比低智力者有更多可变的、更分化的人格。该研究在653名大学生样本中检验了这一假设,结果表明：（1）高IQ组比低IQ组倾向于获得更极端的人格分数,在大多数人格维度上,尤其是外倾性和开放性维度,高IQ组的人格结构更加分化。（2）除神经质与宜人性、外倾性与开放性的相关外,高IQ组在其他特质维度中都比低IQ组有更低的相关和更多的人格结构。（3）没有充分证据表明高IQ组比低IQ组在人格测量中有更高的信度。

英文摘要：

The differentiation of personality hypothesis based on intelligence difference is that the higher IQ group will have greater variability and more differentiation than the lower IQ group in personality scale scores. This paper examined the hypothesis in 653 undergraduates＇ sample, and the results indicated that： （ 1 ） Compared to the lower IQ group, the higher IQ group tended to be obtained more extreme scores in personality scale, and their personality structures were more differentiation in most dimensions, especially extraversion and openness. （ 2 ） Except for the relationship between neuroticism and agreeableness, together with the relation of extraversion and openness, the higher IQ group had lower correlation among the rest of trait dimensions and had more personality structures than the lower IQ group. （3）There were no sufficient evidences indicated that the higher IQ group had higher reliability than the lower IQ group.
