Mean latency to complete five cumulative seconds of drinking in the presence of the tone in subjects tested as adults. Animals were exposed to ten tone-shock pairings on the delay conditioning day. The top panel (Pre-CS; A) depicts the latency to complete five cumulative seconds of drinking prior to CS presentation on test days. The bottom panel (Post-CS; B) depicts the latency to complete five cumulative seconds of drinking in the presence of the CS on test days. The groups differed in whether they had received saline or nicotine (3.0 mg/kg/day, or 6.0 mg/kg/day) during adolescence (PD 28–42). Error bars represent SEMs.
