Description:
Event-related potentials associated with detected targets in a vigilance task were analyzed in two ways: (i) by sorting the potentials in terms of sequential reaction time bins of 50 milliseconds and (ii) by examining the single trial waveforms. A negative component (N2) covaried in latency with reaction time. These results support the hypothesis that N2 reflects a decision process which controls behavioral responses in sensory discrimination tasks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ritter, W -- Simson, R -- Vaughan, H G Jr -- Friedman, D -- New York, N.Y. -- Science. 1979 Mar 30;203(4387):1358-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424760" target="_blank"〉PubMed〈/a〉
