AP Psych Unit 5 Flashcards
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
Synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy, but w/ short-term health risks and longer-term harm to serotonin-producing neurons and to mood and cognition
Ecstasy triggers dopamine, releases stored serotonin-blocking reuptake, which prolongs serotonin’s “feel-good”
Ecstasy (MDMA)
Psychedelic drugs such as LSD that distort perceptions and evoke sensory images in absence of sensory input
Hallucinogens
Altered state of consciousness reported after a close brush with death (such as through cardiac arrest); often similar to drug-induced hallucinations
Near-death experience
powerful hallucinogenic drug, created by Hofmann, trips can range from euphoria to terrifying
LSD
Major active ingredient in marijuana; triggers a variety of effects, including mild hallucinations
THC
Synthetic marijuana that mimics THC, can cause anger and hallucinations
K2/Spice
Decreasing responsiveness w/ repeated exposure to a stimulus
Habituation
Learning that certain events occur together.
The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning).
Associative learning
Any event or situation that evokes a response
Stimulus
Behavior that operates on the environment, producing consequences
Operate behavior
The acquisition of mental information, whether by observing events, by watching others, or through language
Cognitive learning
A type of learning in which one learns to link two or more stimuli and anticipate events
Classical conditioning
The view that psychology (1) should be an objective science that (2) studies behavior w/o reference to mental processes. Most research psychologists today agree w/ (1) but not w/ (2)
Behaviorism
In classical conditioning, a stimulus that elicits no response before conditioning
Neutral stimulus
In classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food’s in the mouth
Unconditioned response
