    Study Notes

    Determinants of Classical Conditioning

    • The intensity of the unconditioned stimuli (US) influences both appetitive and aversive conditioning.
    • More intense conditioned stimuli (CS) are more effective in accelerating the acquisition of a conditioned response (CR). This means fewer trials are needed to establish the CR.
    • More intense US are especially powerful, with extremely intense aversive US potentially leading to Post-Traumatic Stress Disorder (PTSD).
    • Stimuli can be excitatory or inhibitory.
    • Excitatory stimuli predict the occurrence of a stimulus, while inhibitory stimuli predict its absence.
    • An example of an inhibitory stimulus is a bell that signals the absence of food.
    • The presence of a novel stimulus, such as an audience, can inhibit a conditioned response.

    Time Relationships between Stimuli

    • Stimuli can be presented simultaneously, delayed, in trace conditioning, or backward conditioning.
    • Simultaneous Conditioning: CS and US are presented at the same time.
    • Delayed Conditioning: Also known as forward conditioning, the CS precedes the US, with an overlap in presentation.
    • Trace Conditioning: CS is presented, then removed before the US is presented. There is a gap between the two stimuli.
    • Backward Conditioning: The US precedes the CS.

    Acquisition, Extinction, and Spontaneous Recovery

    • Acquisition: The process of learning a CR through repeated pairings of the CS and US.
    • Extinction: The gradual weakening of the CR when the CS is presented without the US.
    • Spontaneous Recovery: The reappearance of a weakened CR after a period of extinction.
    • Rapid Reacquisition: The faster rate of relearning a CR after extinction.

    Rate of Extinction: Total Duration Matters

    • The total duration of exposure to the CS, rather than the number of trials, determines the rate of extinction.
    • This is an important consideration for exposure therapy, where prolonged exposure to the CS without the US can help reduce the CR.

    Inhibition Phenomena

    • Latent Inhibition: Pre-exposure to the CS without the US inhibits later learning. This is discussed in a previous lecture.
    • External Inhibition: The presence of a novel cue during conditioning inhibits the CR.
    • Conditioned Inhibition: A CS predicts the absence of the US.
    • Inhibition of Delay: The CR is withheld until an appropriate time.
    • Disinhibition: The removal of inhibition by the presentation of a novel stimulus.

    Pavlov's "Eureka" Moment

    • External inhibition was discovered accidentally by Pavlov while conducting a lecture.
    • The dog did not demonstrate the CR outside of its usual lab setting.
    • The change in context, moving from the lab to the lecture hall, inhibited the CR.
    • This discovery highlights the importance of context in classical conditioning.
