Abstract

Goal directed behavior depends on a dynamic balance between cognitive flexibility and stability. Identifying factors that modulate the balance between these control states is therefore of major interest for the understanding of human action control. In two experiments we used a hybrid paradigm combining forced- and free-choice task switching and measured spontaneous voluntary switch rate (VSR) as an indicator of cognitive flexibility. In Experiment 1 participants were free to choose a given task on 75%, 50%, or 25% of all trials. In the remaining forced-choice trials task repetitions and switches were roughly equally distributed. Results showed that VSR increases with increasing proportion of forced choices. To clarify whether the frequency of forced choices per se or the frequency of forced task switches in particular drives this effect we conducted Experiment 2. In a fully orthogonal between design participants were free to choose a given task on 75% or 25% of all trials with a predetermined switch rate in the remaining forced-choice trials of 75% or 25%, respectively. Results revealed an interaction of both manipulations: The highest VSR was found for the combination of 75% forced-choice trials with 75% forced switch rate, while VSR for 75% forced-choice trials with 25% forced switch rate was still higher than VSRs in both conditions with 25% forced-choice trials. This suggests that a context of frequent forced task switching changes global control parameters towards more flexible behavior.

保持灵活——保持切换!强制性任务切换对自愿性任务切换的影响

目标导向行为依赖于认知灵活性和稳定性之间的动态平衡。因此，识别调节这些控制状态之间平衡的因素对于理解人类行为控制具有重要意义。在两个实验中，我们使用了一种混合范式，结合了强迫选择和自由选择的任务切换，并测量了自发自愿切换率(VSR)作为认知灵活性的指标。在实验1中，参与者可以在75%、50%或25%的试验中自由选择给定的任务。在其余的强迫选择试验中，任务重复和切换的分布大致相等。结果表明，VSR随强迫选择比例的增加而增加。为了弄清是强迫选择本身的频率还是强迫任务切换的频率驱动了这种效应，我们进行了实验2。在一个完全正交的设计中，参与者可以在75%或25%的试验中自由选择给定的任务，在其余的强制选择试验中，分别有75%或25%的预定切换率。结果显示了两种操作的交互作用:75%强制选择试验和75%强制切换率组合的VSR最高，而75%强制选择试验和25%强制切换率组合的VSR仍然高于25%强制选择试验和25%强制选择试验的VSR。这表明频繁的强制任务切换会改变全局控制参数，使其更灵活。

期刊介绍： Cognition is an international journal that publishes theoretical and experimental papers on the study of the mind. It covers a wide variety of subjects concerning all the different aspects of cognition, ranging from biological and experimental studies to formal analysis. Contributions from the fields of psychology, neuroscience, linguistics, computer science, mathematics, ethology and philosophy are welcome in this journal provided that they have some bearing on the functioning of the mind. In addition, the journal serves as a forum for discussion of social and political aspects of cognitive science.
