AS2 Unit 2 Project Pavlavian Conditioning ADA.dock-Word CES MAILINGS REVIEW VIEW Prior experience with a stimulus affects its tendency to become a Cs. a. If a stimulus appears alone (i.e, without a US), this slows the pace of conditioning when that stimulus is then paired with a US, a phenomenon called If an effective (well-established) CS is presented simultaneously with a new stimulus and the two are called c. When two NS stimu b. coold blstimulus (neutral mlus)tnd NOT to become a cs. This phenomenon s li are presented in compound and followed by a US, only one NS tends to become a CS, a phenomenon known as Take s coe lok t ths re nd s a tocfExplanation / Answer
1.a. ‘Spontaneous recovery’
Spontaneous Recovery of the conditioned response occurs when after a gradual fading of response to the Conditioned Stimulus(CS) in the absence of the Unconditioned Stimulus(UCS), the CS-UCS pairing is repeated.
b.the process of ‘Discrimination’ defines the situation.
When a Conditioned Response occurs in the presence of a Conditioned stimulus but not another neutral stimulus. The organism thus learns to respond to only the CS but not the neutral stimulus.
c. This describes the phenomenon of ‘Overshadowing’.
In compound or higher order conditioning, overshadowing occurs when responding is strong to one neutral stimulus and weak or absent to the other neutral stimulus . For example, in the Pavlovian experiment with eliciting the CR of salivationin the dog, if we introduce a tone-light compound, then the tone may produce stronger conditioned salivation than the light. We would conclude that the tone overshadowed the light.
