In recent years, a number of studies have revealed that cognitive control is strongly context-dependent (e.g., Crump et al., 2006). Inspired by this, computational models have been formulated based on the idea that cognitive control processes are based on associative learning (Blais et al., 2007; Verguts & Notebaert, 2008). Here, we test a natural consequence of this idea, namely, that sequential congruency effects (Gratton et al., 1992) should gradually decrease with an increasing number of task-relevant features (e.g., stimuli). The effect is empirically observed and simulated in a computational model. Implications of our findings are discussed.
近年来，多项研究表明认知控制强烈依赖于情境（例如，Crump等人，2006年）。受此启发，基于认知控制过程基于联想学习的观点构建了计算模型（Blais等人，2007年；Verguts和Notebaert，2008年）。在此，我们测试了这一观点的一个自然推论，即序列一致性效应（Gratton等人，1992年）应随着与任务相关特征（如刺激）数量的增加而逐渐减小。该效应在计算模型中得到了实证观察和模拟。我们讨论了研究结果的意义。
