Abstract

Cognitive flexibility is crucial for adaptive human behaviour. Prior studies have analysed the effect of reward on cognitive flexibility; however, the neural mechanisms underlying these effects remain largely unknown. This study explores how reward influences neural oscillations and how these changes impact behavioural performance. Using time-frequency decomposition, we examined electroencephalographic data from participants engaged in rule-guided task-switching with varying reward prospects. Higher anticipated rewards lead to greater desynchronisation of alpha (8–12 Hz) and beta (20–30 Hz) oscillations, which in turn correlated with improved task performance. Both alpha power and event-related potential (ERP) coding of reward independently predicted reward-based performance improvements, suggesting distinct mechanisms supporting proactive control. These findings underscore the unique contributions of neural oscillations in mediating motivational effects on cognitive flexibility.

α和β振荡介导动机对认知灵活性神经编码的影响。

认知灵活性对于适应性人类行为至关重要。先前的研究分析了奖励对认知灵活性的影响；然而，这些影响背后的神经机制在很大程度上仍然未知。本研究探讨了奖励如何影响神经振荡以及这些变化如何影响行为表现。使用时频分解，我们检查了参与规则引导任务转换的参与者在不同奖励前景下的脑电图数据。更高的预期奖励导致更大的α (8-12Hz)和β (20-30Hz)振荡的不同步，这反过来又与改进的任务表现相关。奖励的α功率和事件相关电位（ERP）编码都能独立预测基于奖励的绩效改善，表明支持主动控制的不同机制。这些发现强调了神经振荡在调节认知灵活性的动机效应方面的独特贡献。

期刊介绍： Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane. The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
