  • Title: Error positivity is related to attentional control of task switching.
    Author: Tanaka H.
    Journal: Neuroreport; 2009 May 27; 20(8):820-4. PubMed ID: 19384255.
    Abstract:
    This study aimed to investigate the relationship between attentional control and action monitoring in a task-switching paradigm by examining the error-related negativity and positivity, components of event-related potentials that reflect action monitoring, including error detection. This study was designed with both a task-switching condition and a single-task condition and the results were compared between the two conditions. Error-related positivity amplitude decreased in the task-switching condition, whereas error-related negativity amplitude did not change in either condition. The results therefore support the notion that the two error-related components represent different aspects of action monitoring, including error detection.
