Neural correlates of unconditioned response diminution during Pavlovian conditioning
Pavlovian conditioning research has shown that unconditioned responses (UCR) to aversive unconditioned stimuli (UCS) are reduced when a UCS is predictable. This effect is known as UCR diminution. In the present study, we examined UCR diminution in the functional magnetic resonance imaging (fMRI) signal by varying the rate at which a neutral conditioned stimulus (CS) was paired with an aversive ...
متن کاملClassical conditioning using stimulation of the inferior olive as the unconditioned stimulus.
We show that conditioned eyelid responses develop when the unconditioned stimulus is electrical stimulation of the dorsal accessory nucleus of the inferior olive. When compared to conditioning using a standard unconditioned stimulus (air puff), the conditioning produced in this manner appears quite normal: the responses develop at a similar rate, are of comparable magnitude and topography, and ...
متن کاملSocially acquired predator avoidance: is it just classical conditioning?
Associative learning theories presume the existence of a general purpose learning process, the structure of which does not mirror the demands of any particular learning problem. In contrast, learning scientists working within an Evolutionary Biology tradition believe that learning processes have been shaped by ecological demands. One potential means of exploring how ecology may have modified pr...
متن کاملEffects of Aversive Classical Conditioning on Habituation of Unconditioned Skin Conductance Response
operations and mechanisms of classical conditioning has been carried out considering the conditioned response (CR) separately and by regarding it as the optimum way of measuring the behavioral manifestation of conditioning. There are fundamentally two theories which have attempted to explain the nature of this response. The theory of the Psicothema, 1998. Vol. 10, no 1, pp. 175-181 ISSN 0214 99...
متن کاملDifferential effects of expectancy and associative mechanisms on diminution of unconditioned response in electrodermal classical conditioning
blink reactions, reduced response to the unconditioned stimulus (US) after repeated pairing of a conditioned stimulus (CS) with the US has been frequently observed (Baxter, 1966; Kimmel, 1967; Kimmel & Pennypacker as described in Kimmel, 1966). This phenomenon has been called «conditioned diminution of the unconditioned response (UR)» (Kimble & Ost, 1961), and a range of explanations have been ...
