    Study Notes

    Instrumental Conditioning

    • Developed by B.F. Skinner, also known as operant conditioning
    • Uses the Skinner box, a small chamber with a lever or key, devices for delivering food or reinforcers, and sensors to detect the animal's behaviour

    Key Concepts

    • Reinforcement: the process of strengthening a behaviour by delivering a consequence that increases the likelihood of the behaviour occurring again in the future
    • Positive Reinforcement: a desirable consequence is presented following the behaviour
    • Negative Reinforcement: an aversive consequence is removed following the behaviour
    • Secondary Reinforcers: stimuli that acquire their reinforcing properties through association with primary reinforcers (e.g., a clicker paired with food delivery)

    Punishment

    • Punishment: presenting an aversive consequence or removing a desirable stimulus contingent upon the occurrence of behaviour, which decreases the probability of the behaviour occurring again
    • Positive Punishment: involves presenting an aversive stimulus following the behaviour
    • Negative Punishment: removal of a desirable stimulus following the behaviour

    Factors Affecting Reinforcer Effectiveness

    • Amount of Reinforcement: the amount of reinforcement received can impact the effectiveness of the reinforcer
    • Motivational Need of Reinforcer: the degree to which the reinforcer satisfies a biological or physiological need
    • Contrast Effects: the difference between the reinforcement and the absence of reinforcement
    • Delay of Reinforcement: the time between the behaviour and the presentation of the reinforcement

    Generalisation and Discrimination

    • Generalisation: the learned behaviour is exhibited in response to stimuli that resemble the original stimulus associated with reinforcement
    • Discrimination: the organism learns to respond differently to stimuli that signal different consequences

    Updates

    • Relativity of Reinforcement: the value of a reinforcer can vary depending on the context
    • Premack Principle: high-probability behaviours can serve as reinforcers for low-probability behaviours
    • Disequilibrium Hypothesis: individuals have a natural balance in their behaviours, and reinforcement can be used to increase or decrease certain behaviours

    Applications

    • Behaviour Modification: a therapeutic approach that aims to change or modify undesirable behaviours
    • Token Economy: a system that uses tokens or symbols to reinforce desirable behaviours
    • Self-Behaviour Modification: uses the ABC approach to change behaviour and reinforces it

    Addiction

    • Addiction: the repeated powerful motivation to engage in purposeful behaviour
    • Stages of Addiction: initiation, maintenance, and addiction
    • Role of Classical Conditioning: associates drug-related cues with physiological cues
    • Role of Instrumental Conditioning: reinforces drug-seeking behaviours through rewarding effects of drugs

    Limitations of Learning Theories of Addiction

    • Oversimplification: based on animal research, which may not translate to humans
    • Automatic Processes: do not take into account human reflective processes
    • Factors that Make Some Drugs More Addictive: ability to activate the incentive and pleasure systems of the brain, tolerance, withdrawal effects, and long-lasting changes in brain incentive systems

    Classical vs Instrumental Conditioning

    • Key Differences: classical conditioning elicits involuntary and automatic responses, whereas instrumental conditioning responses are voluntary
