Response inhibition in conflict tasks is revealed in delta plots

Our main goal in this chapter is to present a method that allows us to examine the proficiency of response inhibition in behavioral (reaction time) data. We review two examples in which we use an analytical technique known as delta-plot analysis to highlight the role of response inhibition in resolving response conflict. The first study is on individual differences in resolving response conflict and included subjects in the normal population. In the second experiment, delta plots were used to mark inhibitory deficits in children diagnosed with attention-deficit/hyperactivity disorder (ADHD). First, we briefly introduce the conflict paradigm.
