A Novel Form of Memory for Auditory Fear Conditioning at a Low-Intensity Unconditioned Stimulus
Fear is one of the most potent emotional experiences and is an adaptive component of response to potentially threatening stimuli. On the other hand, too much or inappropriate fear accounts for many common psychiatric problems. Cumulative evidence suggests that the amygdala plays a central role in the acquisition, storage and expression of fear memory. Here, we developed an inducible striatal ne...
متن کاملOn the respective contributions of awareness of unconditioned stimulus valence and unconditioned stimulus identity in attitude formation through evaluative conditioning.
Evaluative conditioning (EC) is a central mechanism for both classic and current theories of attitude formation. In contrast to Pavlovian conditioning, it is often conceptualized as a form of evaluative learning that occurs without awareness of the conditioned stimulus-unconditioned stimulus (CS-US) contingencies. In the present research, the authors directly address this point by assessing the...
متن کاملEyeblink conditioning with a noise burst as unconditioned stimulus.
BACKGROUND The aim of this study was to determine if a white noise burst could be used as an effective unconditioned stimulus (US) to produce differential conditioning of eyeblink responses that were recorded as EMG activity of the orbicularis oculi. METHOD Two fear-relevant stimuli served as conditioned stimuli (CS). An angry woman’s face (CS+) was consistently followed by a white nois...
متن کاملInteroceptive fear conditioning and panic disorder: the role of conditioned stimulus-unconditioned stimulus predictability.
Interoceptive fear conditioning is at the core of contemporary behavioral accounts of panic disorder. Yet, to date only one study has attempted to evaluate interoceptive fear conditioning in humans (see Acheson, Forsyth, Prenoveau, & Bouton, 2007). That study used brief (physiologically inert) and longer-duration (panicogenic) inhalations of 20% CO(2)-enriched air as an interoceptive conditione...
متن کاملClassical conditioning in rabbits using pontine nucleus stimulation as a conditioned stimulus and inferior olive stimulation as an unconditioned stimulus.
Classical conditioning of skeletal muscle responses was accomplished by pairing microstimulation of the pontine nuclei as a conditioned stimulus (CS) with microstimulation of the dorsal accessory olive as an unconditioned stimulus (US). A conditioned response identical in form to the behavioral response elicited by the olivary stimulation was established when the CS was forward paired with the ...
