AP Psych Unit 5 Flashcards
(98 cards)
A chemical substance that alters perceptions and moods (attention, judgement, memory, self-control, emotion, perception)
Psychoactive drugs
Disorder characterized by continued substance craving and use despite significant life disruption and/or physical risk
Substance use disorder
Diminished control, diminished social functioning, hazardous use, addiction
When drug use is a disorder
Diminishing effect w/ regular use of drug, requiring user to take larger and larger doses before experiencing the drug’s effect
Tolerance
The study of psychoactive drugs
Psychopharmacology
mimic neurotransmitters (excite)
Agonists
prevent neurotransmitters from binding to receptor sites (inhibit)
Antagonists
Physical illness following withdrawal of a drug
Withdrawal symptoms
Reduction in body’s response to a drug (needs more)
Drug tolerance
Drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions
Depressants
Alcohol use marked by tolerance, withdrawal, and a drive to continue problematic use (alcoholism)(CNS numb)
Alcohol use disorder
Opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety (numbs CNS)
Opiates
increase CNS function, higher HR, metabolism energy attention (produce tolerance, withdrawal effects, disturbed sleep, reduced appetite, euphoric response)
Stimulants
active chemical THC, has mild depressant affects, hallucinogenic (relaxation, time distortion, pain relief, perceptual distortions)
Marijuana
Drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions
Depressants
Alcohol use marked by tolerance, withdrawal, and a drive to continue problematic use (alcoholism)
Alcohol use disorder
Drugs that depress the activity of the CNS, reducing anxiety but impairing memory and judgement
Barbiturates
Opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety
Opiates
Drugs such as caffeine, nicotine, coke and ecstasy that excite neural activity and speed up body functions
Stimulants
Stimulating and highly addictive psychoactive drug in tobacco
Nicotine
Powerful and addictive stimulant derived from coca plant, producing temporarily increased alertness and euphoria
blocks reuptake, excess neurotransmitters remain in synapse and produce a rush, when wears off, absence of neurotransmitters like dopamine, serotonin and norepinephrine produce a crash
Cocaine
Drugs such as meth that stimulate neural activity, causing accelerated body functions and associated energy and mood changes
Methamphetamine
Powerfully addictive drug that stimulates the CNS, w/ speeded-up body functions and associated energy and mood changes; overtime appears to reduce baseline dopamine lvls.
Methamphetamine
