Document Summary

Stimulus 1 = press the button with your right index finger (150ms) Stimulus 2= press the button with you left index finger (150ms) If the two tasks are placed in close proximity, you can produce an increase in the second stimuli. Stimulus 2 reaction time increases delay because the information processing is serial and discrete. Delay in responding to the second of 2 stimuli presented in rapid succession. Red line: bottleneck prevents several stimuli from being processed. Red line: reaction time to stimulus 2 if it was on its own. If stimulus 1 and stimulus 2 are 50ms apart; nothing will happen (no psychological refractory period: if the two stimuli are placed close together, we process them as one stimulus. 75-80ms apart = optimal interval to produce psychological refractory period: it produces the longest/biggest increase in the reaction time for stimulus 2, stuck in the psychological refractory period.
