Reaction time and EEG activation under alerted and nonalerted conditions

Reaction time and EEG activation under alerted and nonalerted conditions Reaction time means and SDs did not differ for 3 nonalert (no warning signal) conditions, but were remarkedly reduced when the warning signal produced alpha blocking prior to the visual reaction stimulus. The reduction of RT as a function of the length of the foreperiod interval followed precisely the same time course as the curve showing the degree of alpha blocking as a function of the foreperiod interval. Discussion in terms of function of ascending reticular activating system. 22 refs. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Experimental Psychology: General American Psychological Association

Abstract

Reaction time means and SDs did not differ for 3 nonalert (no warning signal) conditions, but were remarkedly reduced when the warning signal produced alpha blocking prior to the visual reaction stimulus. The reduction of RT as a function of the length of the foreperiod interval followed precisely the same time course as the curve showing the degree of alpha blocking as a function of the foreperiod interval. Discussion in terms of function of ascending reticular activating system. 22 refs.
