Fig. 2: Dwell Time Analysis.

Dwell time on the Cue (panel A) and the Goal (panel B) for CS+ and CS− trials across the four blocks examined in the random effect regression models for the three phenotypes (STs, GTs, and Ints). Note. STs sign-trackers, Ints intermediates, GTs goal-trackers. Bars represent standard error of the mean. *p < 0.05; **p < 0.001; ***p < 0.0001.
