Carioca High-conditioned Freezing (CHF) and Carioca Low-conditioned Freezing (CLF) rats are two linesthat are selectively bred for high and low levels of freezing in response to contextual cues that are previously associated with footshock. These two lines have significantly different traces of anxiety-like responses in different behavioral protocols. The present study used male and female CHF and CLF rats to investigate possible associations between anxietyrelated behavior and alcohol intake. Quinine and saccharin were used as taste control solutions.The results indicated that CHF rats had a higher anxious phenotype and CLF animals had a lower anxious phenotype when both breeding lines were compared with a randomly selected line that was used as a control group. Male rats consistently exhibitedmore conditioned freezing than females. CHF rats consumed more 6 percent and 10 percent alcohol concentrations than CLF rats in a free-choice test and more of a 10 percent alcohol concentration in a forcedchoice test. Female CHF rats exhibited the highest amount of alcohol intake during these three conditions compared with male CHF rats. Female rats also consumed more quinine than male rats. Finally, CHF rats exhibited lower saccharin consumption compared with CLF and control animals. Altogether, these results revealed sex differences in anxiety-like behavior and alcohol consumption,supporting the hypothesis that there is a positive relationship between anxiety and alcohol intake. The Carioca breeding lines were developed for high and low defensive behavior in response to diffusecontextual cues that are associated with footshock but not to well-defined danger-related stimuli, corroborating the view that anxiety but not fear is associated with alcohol consumption.
