Table 2. Effects of pharmacological manipulations of monoaminergic signaling on inhibitory response control.

Upwards arrows indicate that the manipulation increased impulsive responding in the test, while downwards arrows indicate a reduction in impulsive responding in the test. Effects are drawn from studies cited in Section 2.5., 3.5., and 4.4. of the text.
