Document Summary
Learning: relatively enduring change in behaviour due to experience. Animals might learn to avoid and associate danger. Going to gym a lot, body is not in neutral state, body may start feeling energized. Pavlov nobel speech: didn"t talk about research that led. Spent entire speech talking about classical (pavlovian conditioning) Psychology has to look at things that can be objectively measured. Non associative learning: info about one external stimulus. Habituation: decrease in behavioural responding to a repeated stimulus. Sensitization: increase in behavioural responding to a repeated stimulus (watching scary movie, react to everything, hightened sense of awareness) Associative learning: two or more pieces of information are related. Classical conditioning: learn that two stimuli go together. Operant conditioning: learn that a behaviour leads to particular outcome. Long term potentiation (ltp): the strengthening of synaptic connections between neurons. Generally, even with detox, desire and craving for drug remains. Longer you take a drug, more drug tolerance.
