Figure 2

Behavior directed towards the lever CS (sign tracking) is shown in panels a–c and that directed towards the food cup during CS presentation (goal tracking) is shown in panels d–f. Mean+SEM (a) probability of contacting the lever CS (#trials with a lever CS contact/#trials per session) during the 8-s CS period (b) number of lever CS contacts made during the 8-s CS period, (c) latency to the first lever-CS contact, (d) probability of food cup entry (# trials with a food cup entry/#trials per session) during the 8-s CS period (e) number of food cup entries made during the 8-s CS period, (f) latency to the first food cup entry during the CS period. For all of these measures there was a significant effect of group (ST or GT), session, and a group x session interaction (p<0.001).
