Q
  • pulse quickens
  • breathing becomes fast and irregular
  • but our brainstem blocks messages from the motor cortex
  • after, we go back to stage 1
  • brain waves pick up speed and strengthens
  • 8-9 hours asleep–> last 4 hours will be spent more in this stage then first half
  • brain waves look more like someone awake based on brain activity

Study These Flashcards
A

Reasons we dream

24
According to Freud, the underlying meaning of a dream
Latent content
25
The tendency for REM sleep to increase following REM sleep deprivation
REM rebound
26
Neural activity is random, and dreams are the brain's attempt to make sense of it
Activation-synthesis theory
27
A social interaction in which one person suggests to another that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur
Hypnosis
28
The supposed ability to relive childhood experiences
Age regression
29
A suggestion, made during hypnosis session, to be carried out after the subject is no longer hypnotized
Post hypnotic suggestion
30
The subject is so caught up in the hypnotized role that she ignores the cold (ice bath example)
Social influence theory
31
A split in consciousness which allows some thoughts and behaviors to occur simultaneously with others
Dissociation
32
A chemical substance that alters perceptions
Psychoactive drug
33
The diminishing effect with repeated use of the same dose of a drug, requiring the user to take larger and larger doses before experiencing the drug's effects
Tolerance
34
The discomfort and distress that follow discontinuing the use of an addictive drug
Withdrawal
35
A physiological need for a drug, marked by unpleasant withdrawal symptoms when the drug is discontinued
Physical dependence
36
A psychological need to use a drug
Psychological dependence
37
Compulsive drug craving and use, despite adverse consequences
Addiction
38
- addictive drugs quickly corrupt - addictions cannot be overcome voluntarily; therapy is required - we can extend the concept of addiction to cover not just drug dependencies, but a whole spectrum of repetitive, pleasure-seeking behaviors
Myths about addiction
39
Drugs that reduce neural activity and slow body functions
Depressants
40
Alcohol, barbiturates, opiates, date-rape drugs, rohypnol, GHB, ketamine
Depressants
41
- equal opportunity drug - slows neural processing - disrupts the processing of recent experiences into long-term memories - reduces self awareness and self control - pleasurable effects: initial high followed by relaxation and disinhibition - adverse effects: depression, memory loss, organ damage, impaired reactions
Alcohol
42
Drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgement (tranquilizers)
Barbiturates
43
Opium and its derivatives; morphine, heroin, and oxycodone; they depress neural activity, temporarily lessening pain and anxiety
Opiates
44
Tranquilizer; produces sedative effect, amnesia, muscle relaxation and slowed psychomotor response
Rohypnol (rufies)
45
Produces feelings of relaxation, tranquility, sensuality and loss of inhibitions
GHB
46
Powerful animal tranquilizer; causes impaired motor functioning
Ketamine
47
Drugs that excite neural activity and speed up body functions
Stimulants
48
Drugs that stimulate neural activity, causing speeded-up activity body functions and associated energy and mood changes
Amphetamine
49
A powerfully addictive drug that stimulates the central nervous system, with speeded-up body functions and associated energy and mood changes; over time, it appears to reduce baseline dopamine levels - pleasurable effects: euphoria, alertness, energy - adverse effects: irritability, insomnia, hypertension, depressive crash
Methamphetamine (meth)
50
- stimulant - pleasurable effects: rush of euphoria, confidence, energy - adverse effects: cardiovascular stress, suspiciousness, depressive crash
Cocaine (crack)
51
- stimulant - pleasurable effects: arousal and relaxation, sense of well being - adverse effects: heart disease, cancer
Nicotine
52
A synthetic stimulant and mild hallucinogen; produces euphoria and social intimacy, but with short-term health risks and longer-term harm to serotonin-producing neurons and to mood and cognition - pleasurable effects: emotional elevation, disinhibition - adverse effects: dehydration, overheating, depressed mood, impaired cognitive and immune functioning
Ecstasy (MDMA)
53
Psychedelic drugs that distort perceptions and evoke sensory images in the absence of sensory input
Hallucinogens
54
A powerful hallucinogenic drug; also known as acid; chemically similar to a subtype of serotonin
LSD
55
An altered state of consciousness reported after a close brush with death; often similar to drug-induced hallucinations
Near-death experience
56
The major active ingredient in marijuana; triggers a variety of effects including mild hallucinations
THC
57
Pleasurable effects: enhanced sensation, relief of pain, distortion of time, relaxation Adverse effects: impaired learning and memory, increased risk of psychological disorders, lung damage from smoke
Marijuana
