大多数关于技能表现的研究都是相关的,在单个时间点测量的技能和预测因子,这使得很难得出关于获得技能的结论。相比之下,在这项研究中,我们训练新手参与者(N=79)使用7步求解方法求解魔方的立方体。参与者还完成了流体智力(Gf)的测量,工作记忆容量(WMC),和非能力因素(勇气,成长心态,NFC,和“五大”)。总的来说,更高的Gf(但不是WMC)是有效和准确的魔方技能的预测。没有非能力变量与技能相关。我们的结果为智力人才(认知能力)在复杂任务中发展专业知识的重要性提供了令人信服的证据。
Most research on skilled performance is correlational, with skill and predictors measured at a single point in time, making it difficult to draw conclusions about the acquisition of skill. By contrast, in this study, we trained novice participants (N = 79) to solve Rubik\'s Cubes using a 7-step solution method. Participants also completed measures of fluid intelligence (Gf), working memory capacity (WMC), and nonability factors (grit, growth mindset, NFC, and the \"big five\"). Overall, higher Gf (but not WMC) was predictive of efficient and accurate Rubik\'s cube skill. No nonability variables were associated with skill. Our results provide compelling evidence for the importance of intellectual talent (cognitive ability) in developing expertise in a complex task.
