USVs produced (A) and locomotor activity (B) of STs (n = 9) and GTs (n = 14) during saline and cocaine treatment across days in experiment 1. Single asterisks (*) denote differences between STs and GTs on the indicated cocaine-treated days. Double asterisks (**) denote a ST and GT difference on the indicated day as well as a ST within-group difference between Day 16 and Day 23. Data are represented as the mean (+/− SEM). Percentages of occurrence for each of the seven USV categories during Day 23 are shown for both groups (C). Categories were previously based on Wright et al. (2010).
