影响9点问题解决的关键行为

Key Actions in Nine-dot Problem Solving

在已有研究的基础上,作者提出划出第三条线是解决9点问题关键行为的假设,并设计了三个实验来验证假设。结果表明:任意两条线的提示训练使9点问题的解决率接近或达到100%,因而,提示两条线不能被看成是解决9点问题的关键行为;而提示划出第三条线的训练使9点问题的解决率明显高于提示其它任何一条线训练的效果,可以被认为是解决9点问题的关键行为;能够引导被试划出第三条线的训练使9点问题的解决率明显提高。

Based on previous studies by others, the authors hypothesized that drawing out the third line was the key action to solve the nine-dot problem. There were three experiments to verify the hypothesis. The results of these experiments indicated that the solution rate was close to 100% after we clued subjects to any two lines at the same time, clues of two lines weren＇t the key actions to solve the nine-dot problem; the solution rate was significantly higher after we clued subjects to the third line than after cluing subjects to any of the other line alone, drawing out the third line was the key action to solve the nine-dot problem; the training which could lead subjects to draw out the third line significantly made the solution rate higher.
