Fear to the light CS (A,D), during the ITI (B,E), and in the conditioning context (C,F) in females (A–C) and males (D–F). During the light CS test in females (A), there was no effect of interval or training type, but there was interaction between the two factors (P < 0.05). There were no significant differences in males, and there were no significant differences in either sex in fear during the ITI (B,E). During the context test, delayed shock animals showed higher levels of fear in both sexes (C,F), but there was no effect of training interval and no interaction.
