The Effects of Response and Stimulus Repetition across Sequences of Trials in Go/No-go Tasks

Previous research has found inconsistent repetition effects from the immediately preceding trial in choice-RT tasks. The current study focused on the effects of response and stimulus repetitions, respectively, over a sequence of preceding trials in go/no-go tasks. In all of the three experiments, we found that additional go trials preceding the current trial sped up responding but caused false alarms and additional no-go trials slowed responding but reduced false alarms. We also found that repeatedly responding to the same stimulus sped up responding without increasing false alarm rates. Finally, increasing the speed stress did not alter this pattern.
