摘要: The present study examined the temporal pattern of responding in a conditioned bar-press suppression task rats. Rats were exposed to either 30-s or 120-s stimulus (CS) followed by footshock. Training took place while rats lever-pressing for water (online), with lever removed from box (offline). They then CS they water, training context different context. Bar-press during was constant across duration training, but restricted initial portion at time testing, especially when subjects tested Those results replicate reactive (as opposed anticipatory) observed lick procedure Jozefowiez et al. (2011) and indicate that change testing might be critical its expression.
