Addiction (class) Flashcards
continuation of drug use to avoid symptoms
physical dependence
motivated by craving (emotional state or intense desire)
psychological dependence
withdrawl symptoms are antithetical to drug effects.
- -> negative reinforcement (takes away pain)
- -> immediate (reward)
physical dependence
memory of the reward and a negative emotional state combine
- positive reinforcement (even at a steady state)
- -> delayed/ temporary (reward)
psychological dependence
why is the reward temporary/ delayed for the psychological dependence
- because the physiological system is getting involved but there is no down regulation
why is there a debate if physical and psychological dependence be separated
- with physical dependence you might feel so bad you will want the drug just to feel better (psychological)
why can the “urge” be considered a withdrawal
not homestatic, but maybe reverse allostasis? psychological mechanisms are there but not physiological
in extreme cases one ?
wants it more and enjoys it less (reward predicting stimuli)
