Conditioned Reinstatement in Rats: Effects of Exposure Distribution and Type of Cue

Abstract
2 experiments examined the influence of interpolated exposure to conditioned cues upon retention in immature rats. In Exp. 1, distributed exposures or a massed exposure shortly before the retention test significantly improved memory relative to an untreated retention control group. In Exp. 2, brief exposures to distinctive apparatus stimuli previously paired with shock were effective in preventing retention loss while exposures to the compartment never associated with shock did not result in a reliable difference from the retention controls.
