Figure 4.

At least two weeks after the forced swim test in adulthood, rats were tested for sucrose preference over 2 hours. The percentage of sucrose consumed as a percentage of total fluid consumption (ie. Sucrose preference) during the first hour (a), second hour (b), and total 2hour consumption (c) are shown. Group sizes were Male control: n=9, male isolated: n=10, female control: n=9, female isolated: n=10. Overall, consumption was greater in the second hour compared to the first hour (not indicated), regardless of sex of adolescent stress experience. Furthermore, control females exhibited a significant (p<0.05) increase in consumption from the 1^st to the 2^nd hour, whereas isolated females exhibited similar consumption on the 1^st to the 2^nd hour (indicated by the bar in a). Adult females that had been isolated as adolescents exhibited a tendency (p<0.07) for increased sucrose consumption during the first hour compared to control adult male rats that had been isolated during adolescence (indicated by the + symbol). There was a tendency (p<0.06) for a significant interaction effect in total sucrose consumption and t-tests indicated that isolated females exhibited increased sucrose preference compared to control females (*; p<0.05).
