EEG activity represents the correctness of perceptual decisions trial-by-trial

Abstract: Performance monitoring is an executive function, which we depend on for detecting and evaluating the consequences of our behavior. Although event related potentials (ERPs) have revealed the existence of differences after correct and incorrect decisions, it is not known whether there is a trial-by-trial representation of the accuracy of the decision. We recorded the electroencephalographic activity (EEG) while participants performed a perceptual discrimination task, with two levels of difficulty, in which they … Show more

“…Our findings demonstrate that postural threat does affect risk-sensitivity in movement, and the threat may induce risk-aversion in a salient movement task. Future work may benefit from harnessing fMRI (Wu et al, 2009 , 2011 ) or electroencephalography (EEG) (Pardo-Vazquez et al, 2011 , 2014 ) to examine how threat affects the encoding of sensorimotor decisions.…”

“…A solution to this limitation is reflected in the use of trial-by-trial analysis. Such an analysis was performed by Pardo-Vazquez et al ( 2014 ) on performance monitoring ERPs. Another limitation comes from the difference wave measure: it is reductive and often masks processes going on, especially since the ERN overlaps at least one, or more components (Gehring et al, 2011 , see Figure 10.21).…”
