PSYCH 1X03 Lecture Notes - Lecture 3: Classical Conditioning, Operant Conditioning, Habituation
Document Summary
Learning : relatively enduring change in behaviour due to experience. Pavlov : re exive responses associated with cues. Information about one external stimulus: habituation : decrease in behavioural responding to a repeated stimulus, sensitization: increase in behavioural responding to a repeated stimulus. How two or more pieces of information are related. Classical conditioning learn that 2 stimuli go together. Operant conditioning learn that a behaviour leads to a particular outcome. Long-term potentiation strengthening of synaptic connections between neurons. Functional changes in the addicted brain affects future choice of behaviours. Brains of addicts response to taking the drug, but also to drug-associated cues: increased activity at anterior angulate cortex. Drug effects decrease with repeated administration, leading to tolerance. We learn effects of behaviour through operant (instrumental) conditioning. The learning between voluntary behaviour and its consequences. Shaping rewarding bits until behaviour is achieved. Secondary reinforcers established through conditioning; use secondary to get primary.
