Effects of post-response arousal on cognitive control: Adaptive or maladaptive?

Area of Science:

• Cognitive Neuroscience
• Psychophysiology

Background:

• The cognitive control literature suggests that detecting performance errors can lead to adaptive adjustments in attention and performance.
• However, alternative theories propose that error detection might elicit maladaptive arousal, impairing subsequent cognitive functions.

Purpose of the Study:

• To investigate the effects of error detection on subsequent attention and performance.
• To differentiate between maladaptive arousal and adaptive control hypotheses following errors.

Main Methods:

• Utilized a Stroop task with spatial cueing.
• Simultaneously recorded electroencephalography (EEG) and pupillary responses.
• Analyzed the error-related negativity (ERN) component of event-related potentials (ERPs).

Main Results:

• Error detection was associated with increased arousal, indicated by pupil dilation and alpha-band EEG suppression.
• Neural evidence suggested enhanced spatial cueing post-error, but this did not translate to performance improvements.
• Performance was slower and less accurate after errors, with higher arousal predicting next-trial decrements.

Conclusions:

• Findings support the maladaptive arousal account of post-error cognitive control.
• Limited evidence was found for adaptive control mechanisms following performance errors.
