Systematic research into implicit learning requires well-developed awareness-measurement techniques. Recently, trial-by-trial measures have been widely used. However, they can increase complexity of a study because they are an additional experimental variable. We tested the effects of these measures on performance in artificial grammar learning study. Four groups of participants were assigned to different awareness measures conditions: confidence ratings, post-decision wagering, decision strategy attribution or none. Decision-strategy-attribution participants demonstrated better grammar learning and longer response times compared to controls. They also exhibited a conservative bias. Grammaticality by itself was a stronger predictor of strings endorsement in decision-strategy-attribution group compared to other groups. Confidence ratings and post-decision wagering only affected the response times. These results were supported by an additional experiment that used a balanced chunk strength design. We conclude that a decision-strategy-attribution procedure may force participants to adopt an analytical decision-making strategy and rely mostly on conscious knowledge of artificial grammar.
对内隐学习的系统研究需要完善的意识测量技术。最近,逐次试验测量方法已被广泛使用。然而,它们会增加研究的复杂性,因为它们是一个额外的实验变量。我们测试了这些测量方法对人工语法学习研究中表现的影响。四组参与者被分配到不同的意识测量条件下:信心评级、决策后投注、决策策略归因或无。与对照组相比,决策策略归因组的参与者表现出更好的语法学习能力和更长的反应时间。他们还表现出保守偏差。与其他组相比,在决策策略归因组中,语法性本身是字符串认可的更强预测指标。信心评级和决策后投注仅影响反应时间。这些结果得到了另一个使用平衡组块强度设计的实验的支持。我们得出结论,决策策略归因程序可能会迫使参与者采用分析性决策策略,并主要依赖对人工语法的有意识知识。
