Both the type of work and pattern of sleep are no longer compatible with previous society. Previous researches have suggested that the executive function controlled by the frontal lobe is affected by sleep deprivation. Moreover, the literatures have also proposed sleep deprivation might impair error monitoring abilities. There was one recent study (Hsieh et al., 2007) using the letter flanker task demonstrated sleep deprivation only affected the correction rate of stimulus incongruent trials. It is still unclear how the sleep deprivation modulates the error monitoring system. The present study aimed to clarify the relationship among sleep deprivation, the nature of the task, and error correction system. Contrary to the previous study (Hsieh et al., 2007), we used the arrow flanker task to further investigate the relationship between sleep deprivation and error correction processes. Thirteen young healthy adults (5 women, 13-23 years old) executed an arrow flanker task after normal sleep and after one night of sleep deprivation, respectively. They were instructed to make correction immediately when they detected errors. Behavioral and event-related potential (ERP) data were collected through the task. After sleep deprivation, the behavioral results showed significant decreases in overall accuracy and correction rate, and increases in response time and omission rate. The ERP results showed the amplitude of Pe was significantly attenuated after sleep deprivation while the ERN amplitude was not significantly different from normal sleep. Furthermore, there were post error adjustments in both normal sleep and sleep deprivation conditions. In summary, the present study suggested that different versions of the flanker task interacted with sleep deprivation and this may influence error correction system and post error adjustments. Further study is needed to investigate how error correction interacts with post error adjustments under different tasks after one night sleep deprivation.
