Biological clock, regular bodily rhythms like temp and wakefulness that occur on a 24 hour cycle
8
Q
How does bright light mess with our clock?
A
Activates light sensitive retinal Proteins, which control the clock by triggering signals to the brains suprachiasmatic nucleus (SCN)
9

What is the suprachiasmatic nucleus (SCN)
A
A pair of grain of rice sized cell clusters in the hypothalamus and causes pineal gland to increase or decrease sleep hormone melatonin

24
Q
What is sleeps function
A
Sleep protects-better to sleep than try to survive at night, helps us recuperate- restore brain tissue, makes memories-restore memories of day, recall tasks better after sleep, feeds creative thinking-boost think and learn sleep on problem, and may play a role in growth processes-pituitary releases growth hormone

40
Sleep theory: freuds wish fulfillment
Dreams provide a psychic safety value- expressing otherwise unacceptable feelings, contain manifest content (remembered) and a deep layer of latent context (hidden)
41
Sleep theory: freuds wish fulfillment critics
Lacks any scientific support, dreams may be interpreted in many different ways
42
Sleep theory: information processing
Dreams help us sort out the day's events and consolidate our memories
43
Sleep theory: information processing critics
But why do we sometimes dream about things we have not experienced
44
Sleep theory: physiological function
Regular brain stimulation from REM sleep may help develop and preserve neural pathways
45
Sleep theory: physiological function critics
Does not explain why we experience meaningful dreams
46
Sleep theory: activation synthesis
REM sleep triggers neural activity that evokes ransom visual memories which our sleeping brain weaves into stories, tries to make sense of
47
Sleep theory: activation synthesis critics
The individual's brain is weaving the stories, which still tells us something about the dreamer
48
Sleep theory: Cognitive development
Dream content reflects dreamers cognitive development- their knowledge and understanding
49
Sleep theory: cognitive development critics
Does it address the neuroscience of dreams
50
REM rebound
Tendency for REM sleep to increase following REM sleep deprivation (repeated awakenings during REM)
51
Hypnosis
Social interaction in which one person (hypnotist) suggests to another (subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur
52
Postural away

54
Hypnotic ability
The ability to focus attention totally on a task, to become imaginatively absorbed in it, to entertain fanciful possibilities
55
Can hypnosis enhance recall of forgotten events
No, not as far back as childhood
56
Age regressed people, evidence against
People act as they believe a child would but typically out perform the child, example print as a child would but they would do so with perfect spelling and without any changes in adult brain waves
57
Hypnotically refreshed memories...
Combine fact with fiction, so courts can't use testimony from witnesses hypnotized
58
Can hypnosis force people to act against their will
Not necessarily, concluded an authoritative person in a legitimate context can induce people hypnotized or not to perform some unlikely acts
59
Post hypnotic suggestions
Suggest made during hypnosis and carried out afterward
60
Can hypnosis be therapeutic

61
Can hypnosis alleviate pain
Yes, they feel
| Less pain, even used in surgery
62
Social influence theory
Hypnosis like behaviors associated with other supposed altered states like demon possession are an extension of everyday social behavior and not just something unique to hypnosis
63
Dissociation
Split between different levels of consciousness
64
Attention is diverted from a painful ice bath, how?
Divided consciousness theory: hypnosis has caused a split in awareness
Social influence theory: so caught up in hypnosis role that ignores cold
65
Hypnotic pain relief
Does not block sensory input but it may block our attention to those stimuli which
66
Unified account of hypnosis
Extension both of normal principles of social influence and if everyday dissociations between our conscious awareness and automatic behaviors
67
Hypnosis bio influence
Distinctive brain activity
| Unconscious information processing
68
Hypnosis psychological influences
Focused attention
Expectations
Heightened suggestibility
Dissociation between normal sensations and conscious awareness
69
Hypnosis social cultural influences
Presence of an authoritative person in legitimate context
| Role playing good subject
70
Tolerance
Diminishing effect with regular use of the same dose of drug, require larger dose before same effect
71

76
True or false, addictive drugs quickly corrupt, like morphine leads to Heroin
False, morphine to control pain rarely develop cravings of an addict who uses it for mood altering drug
77
True or false, addictions cannot be overcome voluntarily, therapy is required
False, people often recover on their own, viewing addiction as a disease can under mine self confidence
78
True or false, we can extend the concept of addiction to cover not just drug dependencies but a while spectrum of repetitive pleasure seeking behaviors
False, this makes addiction an all purpose excuse. Explain away behavior as illness. But sometimes can be an addiction
79
What are the theee major categories for psychoactive drugs
Depressants, stimulants and hallucinogens
80
Depressants
Drugs (like alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions
81
True or false, in large amounts alcohol is a depressant and in small amounts it is a stimulant
False
82
What does alcohol do
```
Lowers our inhibitions
Slows neural processing
Disrupts memory formations
Reduces self awareness
Stem from expectancy effects too
```
83
What three factors influence correlation between alcohol and sex
Peer influences
Desire for sex leads to drinking and partner drinking
Men disposed to sexual aggression after drinking
84
Barbiturates
Drugs that depress the activity of CNS, reducing anxiety but imparting memory and judgement
Mimic effects of alcohol
85
Opiates
Opium and derivatives, like narcotics morphine and heroin
| Depress neural activity, temporally lessening pain and anxiety
86
What are natural body opiates
Endorphins
87
Stimulants
Drugs like caffeine and nicotine that excite neural activity and speed up body functions
88
Amphetamines
Drugs that stimulate neural activity, causing sped up body functions, associated with energy and mood changes
89
Methamphetamine
Drug stimulates CNS, speed up body functions and associate energy and mood changes, overtime reduce baseline dopamine levels
90
Smoking targets teens by using
```
Sophistication
Independence
Adventure seeking
Social approval
Celebs
```
91
Insula
Area of brain that lights up when people crave drugs
92
How does cocaine produce euphoria rush
Blocks reuptake of dopamine norepinephrine and serotonin at receptor site, so remain in synapse, intensifying and producing euphoric rush, when cocaine level drops, the absence of neurotransmitters produces crash
93
Ecstasy (MDMA)
Synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy. Long term harm to serotonin and mood and cognition
94

96
THC
Major active ingredient in marijuana, triggers variety of effects including mild hallucinations
97
What has recent discovery or cannabinoid receptors led to
Successful hunt for naturally occurring THC molecules that bind with those receptors, may naturally control pain and explain why marijuana can be therapeutic for those suffering from pain
98
Psychoactive drugs have one common feature
They trigger negative after effects that offset these immediate positive effects and grow stronger with repetition
