    Study Notes

    Learning and Memory Basics

    • Learning involves lasting changes in behavior driven by experience.
    • Memory acts as a recording system for experiences that facilitate learning.
    • Key terms include Unconditioned Response (UR), Conditioned Response (CR), Unconditioned Stimulus (US), and Conditioned Stimulus (CS).

    Important Figures

    • Ebbinghaus researched the forgetting curve and conducted practice experiments.
    • Pavlov is known for pioneering classical conditioning concepts using US, UR, CS, and CR.
    • Thorndike formulated the Law of Effect and Instrumental Conditioning.

    Theoretical Approaches

    • Behaviorism emphasizes observable behavior changes through reinforcement, as seen in works by Pavlov and Skinner.
    • Cognitive Psychology studies the impact of mental processes, including memory, on behavior, characterized by Tolman's cognitive maps.

    Classical Conditioning

    • Generalization occurs when organisms react similarly to stimuli akin to the CS; discrimination allows distinct responses.
    • Blocking refers to a more potent stimulus overshadowing another, hindering new associations.

    Classical Conditioning Paradigms

    • Rescorla-Wagner Model explains association formation between CS and US, which adjusts based on trial outcomes.
    • Second-Order Conditioning enables pairing a new stimulus with an established CS to elicit a CR.
    • Sensory Preconditioning involves prior pairing of two neutral stimuli resulting in a conditioned response later.

    Neural Basis of Learning and Memory

    • The cerebellum plays a vital role in motor control and learning.
    • The hippocampus is essential for memory consolidation.
    • Synaptic connections among neurons are crucial for learning processes.

    Classical Conditioning in Simple Organisms

    • Studies with sea slugs have demonstrated synaptic changes associated with learning.

    Classical Conditioning Basics

    • Classical conditioning occurs when a neutral stimulus becomes linked to a response through repeated pairing with a US.
    • Unconditioned Stimulus (US) naturally elicits a response, while a Conditioned Stimulus (CS) becomes associated with the response after conditioning.
    • The resulting Conditioned Response (CR) follows exposure to the CS.

    Processes of Classical Conditioning

    • Acquisition marks the phase of pairing CS with US, strengthening the CR.
    • Extinction happens when the CS is presented without the US, causing a reduction in CR.
    • Generalization results in similar stimuli eliciting the CR.
    • Discrimination allows for recognition of differences among stimuli to respond to only the CS.

    Key Experiments

    • Eye-blink conditioning illustrated this process, using an air puff (US) to evoke a blink (UR/CR) connected to a tone or light (CS).
    • The Little Albert experiment showcased generalization, where a child developed fear towards a white rat (CS) and related furry objects.

    Sensitization and Habituation

    • Sensitization involves an increase in response to a stimulus after repeated exposure.
    • Habituation denotes a decrease in response to a stimulus over time.

    Neural Basis of Classical Conditioning

    • Research on the sea slug Aplysia explores synaptic connections changing during learning.
    • Facilitating interneurons release neurotransmitters, enhancing responses during conditioning.

    Rescorla-Wagner Theory

    • Suggests learning is influenced by the unexpectedness of the US.
    • Formula ΔV = α(λ - V) describes the change in associative strength (ΔV) based on the learning rate (α) and the difference between maximum association (λ) and current strength (V).
    • Blocking effect prevents formation of new associations if an established CS is a better predictor for the US.

    S-R vs. S-S Associations

    • S-R (Stimulus-Response) describes the direct elicitation of UR by CS.
    • S-S (Stimulus-Stimulus) indicates that CR arises from the anticipation of US predicted by CS.

    Key Paradigms

    • Sensory Preconditioning pairs two stimuli before one links to a US, leading to a response with subsequent presentations of either.
    • Second-Order Conditioning introduces a new stimulus associated with the CS, also prompting the CR.
