‘Unconditioned’ refers to the contrast Shock vs. CS- offset during fear conditioning, ‘Conditioning’ refers to the CS+ vs. CS- contrast during fear conditioning, ‘Extinction’ refers to the late CS+ vs. late CS- of the extinction training, and ‘Recall’ refers to the early CS + E trials vs. early CS + U trials of the extinction recall test. (n.s. = no significant main effect of group)
