The present study was designed to bring out the differences between extraverts and introverts on Standard Progressive Matrices. A group of 100 subjects of equal number of sexes were given a qualitative analysis of their performance on SPM. The study brought out the initial superiority of extraverts over introverts. But with passage of time and increase in difficulty level the introverts did significantly better as shown both by the t-ratios and the F-ratios. Personality interacted with sex to yield differences in performance of wrong scores only. These findings were discussed in terms of arousal, cortical excitation and reactive inhibition.
本研究旨在揭示外向者和内向者在标准渐进矩阵测验中的差异。对100名男女数量相等的受试者在标准渐进矩阵测验中的表现进行了定性分析。研究表明，一开始外向者比内向者表现更优。但随着时间推移和难度增加，内向者的表现明显更好，这在t检验比率和F检验比率中都得到了体现。性格与性别相互作用，仅在错误分数的表现上产生差异。从唤醒、皮层兴奋和反应抑制的角度对这些发现进行了讨论。
