The capacity for random movement production is known to be limited in humans (e.g., Newell, Deutsch, & Morrison, 2000). We examined the effects of a brief mindfulness induction on random movement production because there are useful implications for variability in solving movement-related problems. The main task involved randomly clicking the 9 boxes in a 3 × 3 grid presented on a computer screen for five minutes. We characterized the sequence of clicking in terms of degrees of randomness, or periodicity, based on the fit, or probability, of the experimental data with its best fitting Bayesian network (4-click memory nodes) using the Markov chain Monte Carlo (MCMC) approach. Sixty-three participants were randomly assigned to either the experimental or the control condition. Mixed design repeated-measures ANOVA results show that the short mindfulness induction had a positive effect on the randomness of the sequence subsequently produced. This finding suggests that mindfulness may be a suitable strategy for increasing random movement behavior.
众所周知,人类产生随机运动的能力是有限的(例如,Newell、Deutsch和Morrison,2000年)。我们研究了短暂的正念诱导对随机运动产生的影响,因为这对解决与运动相关问题的变异性具有有益的启示。主要任务是在电脑屏幕上呈现的3×3网格中随机点击9个方框,持续五分钟。我们根据实验数据与最佳拟合贝叶斯网络(4点击记忆节点)的拟合度或概率,使用马尔可夫链蒙特卡罗(MCMC)方法,以随机性或周期性的程度来表征点击序列。63名参与者被随机分配到实验条件或对照条件。混合设计重复测量方差分析结果表明,短暂的正念诱导对随后产生的序列的随机性有积极影响。这一发现表明,正念可能是增加随机运动行为的合适策略。
