Mod 3.7a – “Classical Conditioning: Basic Concepts”
Learning: A lasting change in behavior due to experience.
Habituation: Decreased response to a repeated stimulus over time.
Associative Learning: Learning that two events occur together (like stimulus + response).
Behaviorism: Psychology view that studies behavior without referencing mental processes.
Classical Conditioning: Learning to link two stimuli to anticipate events.
NS (Neutral Stimulus): A stimulus that initially produces no response.
UCS (Unconditioned Stimulus): A stimulus that naturally triggers a response.
UCR (Unconditioned Response): The natural response to the UCS.
CS (Conditioned Stimulus): Previously NS, now triggers a learned response.
CR (Conditioned Response): Learned response to the CS.
Acquisition: The initial stage of learning the stimulus-response link.
Extinction: The weakening of a CR when the CS is no longer paired with the UCS.
Spontaneous Recovery: Reappearance of a weakened CR after a rest period.
Generalization: Responding similarly to stimuli like the CS.
Discrimination: Learning to respond only to the CS, not similar stimuli.
Mod 3.7b – “Classical Conditioning: Applications & Biological Limits”
Preparedness: Biological tendency to learn certain associations (like fear of snakes) more easily.
Taste Aversion: Avoiding a food after getting sick from it, even once.
Mod 3.8a & b – “Operant Conditioning”
Operant Conditioning: Learning where behavior is strengthened or weakened by consequences.
Law of Effect: Behaviors followed by rewards are more likely to happen again.
Operant Chamber/Skinner Box: A box used to study animal behavior and rewards.
Reinforcement: Increases behavior.
Positive Reinforcement: Adding something pleasant to increase behavior.
Negative Reinforcement: Removing something unpleasant to increase behavior.
Shaping: Gradually guiding behavior using reinforcers toward a desired outcome.
Primary Reinforcers: Naturally satisfying (like food or water).
Secondary Reinforcers: Learned value (like money or praise).
Continuous Reinforcement: Reinforcing the behavior every time it occurs.
Partial/Intermittent Reinforcement: Reinforcing only sometimes; slower learning but more resistant to extinction.
Fixed-Ratio: Reinforce after a set number of responses.
Variable-Ratio: Reinforce after an unpredictable number of responses.
Fixed-Interval: Reinforce after a fixed amount of time.
Variable-Interval: Reinforce after changing time intervals.
Punishment: Decreases behavior.
Positive Punishment: Adding something unpleasant to reduce behavior.
Negative Punishment: Taking away something pleasant to reduce behavior.
Mod 3.9 – “Social, Cognitive, & Neurological Factors in Learning”
Cognitive Map: Mental layout of an environment.
Latent Learning: Learning that happens but isn’t shown until there’s a reason to use it.
Insight Learning: Sudden realization of a solution without trial and error.
Observational Learning: Learning by watching others.
Modeling: Imitating someone else’s behavior.
Mirror Neurons: Brain cells that fire both when we act and when we see someone else act.
Prosocial Behavior: Positive, helpful actions.
Antisocial Behavior: Negative, harmful actions.
