Table 3.

Latency to respond in experiment 2b (guanfacine vs vehicle). The group average of the individual median correct response latency, incorrect latency and reward response latency for infusion sessions is presented in seconds. There were no significant differences in correct (F(3,39) = 0.445, p = 0.723), incorrect (F(3,39) = 0.239, p = 0.871) or reward collection latencies (F(3,39) = 0.159, p = 0.923)

Guanfacine low	1.800	0.059	2.017	0.097	1.496	0.039
