In three experiments using the barpress conditioned suppression task with albino rats, we studied the renewal (relapse) of conditioned fear in an ABA fear-renewal paradigm. We found that explicitly unpaired (EU) deliveries of conditioned stimuli (CSs

In four experiments using albino rats in an ABA fear renewal paradigm, we studied conditioned fear in the A test context following extinction in Context B. Conditioned suppression of operant responding was the index of fear. In Experiments 1–3, we

Using barpress conditioned suppression, we studied the renewal of conditioned fear in rats, an animal model for the relapse of human fears and phobias. We demonstrated ABA renewal when the only differences between Contexts A and B included (1) their

Prenatal cocaine exposure has been shown to produce attentional changes in human infants and children, as well as in preweanling and young adult animals. The aim of the current study was to determine whether attentional effects of in utero cocaine ex

Prenatal cocaine exposure results in deficits in sensory preconditioning, discrimination reversal, and spatial navigation, tasks that require input from the hippocampus. However, there are no previous studies concerning prenatal cocaine effects on co

We examined the effects of tone, light, and dark conditioned stimuli (CSs) on barpress suppression and freezing in rats. We found more freezing to tone than to light or dark yet similar barpress suppression. In compound, the auditory and visual stimu

In a conditioned suppression task with rats, we used retention-interval and context-switch maneuvers in an effort to affect retrieval of interfering associations often held responsible for the effects of preexposing conditioned stimuli (CSs). In Expe

In experiments using a total of 144 albino rat subjects, the authors assessed the ability of fear-weakening treatments to prevent fear renewal (relapse). Conditioned suppression of operant behavior served as the measure of fear in an A-B-A (acquisiti

One-trial context fear conditioning with immediate shock: The roles of transport and contextual cues

Animal Learning & Behavior. 28:162-171
In three experiments, using a total of 120 albino rats, we assessed whether transportation cues might evoke some of the freezing (i.e., defensive immobility) that we see in a context on a day following a footshock given immediately after placement in

In each of two experiments, we studied Pavlovian fear conditioning (as assessed by barpress conditioned suppression) in 32 albino rats. Following a two-stage cue-competition procedure (A+ then AX+), we subjected the competing cue (A) to conditioned i
