Do CS-US Pairings Actually Matter? A Within-Subject Comparison of Instructed Fear Conditioning with and without Actual CS-US Pairings
Previous research showed that instructions about CS-US pairings can lead to fear of the CS even when the pairings are never presented. In the present study, we examined whether the experience of CS-US pairings adds to the effect of instructions by comparing instructed conditioning with and without actual CS-US pairings in a within-subject design. Thirty-two participants saw three fractals as CS...
متن کاملConditioned inhibition of fear resulting from negative CS-US contingencies.
Two experiments are reported which indicate that negative contingencies between CSs and shock set up conditioned inhibitors. In Experiment 1, this inhibition was measured by retardation in the subsequent acquisition of a CER to the CS. Stimuli with greater negative CS-US contingencies were more retarded in CER acquisition; various control procedures were employed. In Experiment 2, inhibition wa...
متن کاملLatent Inhibition of US Signal Value Following CS-US Training
Two experiments with rats examined latent inhibition of unconditioned stimulus (US) signal value. In Experiment 1, latent inhibition (LI) rats showed attenuated conditioning, compared to control (C) rats, when a single food pellet, delivered 10 min into a session, was followed by three additional pellets. In preexposure, one pellet had been delivered 10 min into the session (in Group LI), or pl...
متن کاملConsolidation of CS and US representations in associative fear conditioning.
Much attention has been paid to the associative processes that are necessary to fuse together representations of the various components of an episodic memory. In the present study, we focus on the processes involved in the formation of lasting representations of the individual components that make up a fear-conditioning episode. In one-trial contextual fear conditioning experiments, weak condit...
متن کاملThe effect of US signalling and the US–CS interval on backward conditioning in mice
The effect of US signalling and the US-CS interval in backward conditioning was assessed in mice. For one group of mice the presentation of food was signalled by a tone and for another group, food was unsignalled. For half of the mice, within each group, the presentation of food preceded a visual cue by 10 s. For the other half, food was presented at the start of the visual cue (0-s US-CS inter...
