    Dual processing
    The principle that information is often simultaneously processed on separate conscious (deliberate, high road) and unconscious (automatic, low road) tracks. Selective attention
    The focusing of conscious awareness on a particular stimulus Inattentional blindness
    Failing to see visible objects when our attention is directed elsewhere Change blindness
    Failing to notice changes in the environment
    Circadian rhythm
    The biological clock; regular bodily rhythms (temperature, wakefulness) the occur on a 24-hour cycle REM sleep
    Stage 5
    Rapid eye movement sleep, a recurring sleep stage during which vivid dreams occur (also known as paradoxical sleep – muscles relaxed, other body systems active) Alpha waves
    The relatively slow brain waves of a relaxed, awake state
    Sleep spindles
    Occurs during stage 2
    Stage 1
    Transition into sleep
    Stage 2
    Beginning of slow wave
    Stage 3

    A psychological need to use a drug, such as to relieve negative emotions Addiction
    Compulsive drug craving and use, despite adverse consequences Depressants
    Drugs (alcohol, opiates) that reduce neural activity and slow body functions Barbiturates
    Drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgment Opiates
    Opium and derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety Stimulants
    Drugs that excite neural activity and speed up body functions (caffeine, cocaine) Hallucinogens
    Psychedelic drugs that distort perceptions and evoke sensory images in the absence of sensory input Near-death experience
    An altered state of consciousness reported after a close brush with death (such as through cardiac arrest); often similar to drug-induced hallucinations The cocktail party effect

    Psych Ch. 3 – Consciousness & The Two Track Mind
    Key terms

    Psych Ch. 3 – Consciousness & the Two Track Mind
    Vision/visually guided actions – dual processing unit
    Much of our everyday thinking, feeling and acting operates outside our
    conscious awareness We process most information outside our conscious awareness
    Sleep and dreams
    Sleep deprivation can cause difficultly studying, diminished productivity, tendency to make mistakes, irritability, fatigue, increases hunger arousing hormone ghrelin and stress causing cortisol, decreases hunger suppressing leptin, suppress immune cells that fight off viral infections and cancer Sleeps functions:

    it protects ( giraffes 2 hours, bats 20 – fits there ecological niche) Helps us recuperate – helps restore and repair brain tissue Makes memories – restores and rebuilds fading memories from the day Feeds creative thinking – dreams can inspire noteworthy literary/artistic/scientific achievements May play a role in the growth process – during deep sleep the pituitary gland releases a growth hormone Sleeping pills and alcohol can aggravate troubles sleeping not help – reduces REM sleep Natural alternative solutions

    Exercise regularly but not in the late evening ( late afternoon is best) Avoid all caffeine after late afternoon & avoid rich foods before bedtime Glass of milk before bed provides the raw materials for the manufacture of serotonin Relax before bedtime – use dimmer lights

    Sleep on a regular schedule
    Hide the clock face to not be tempted to check it repeatedly Reassure yourself that a temporary loss of sleep causes no great harm 8/10 dreams are marked with a negative experience or emotion ( people commonly dream of repeatedly failing in an attempt to do something, being attacked, pursued or rejected, experiencing misfortune Sensory stimuli in our sleeping environment can protrude on our dreams ( phone ringing, odor) To remember a dream – get up and stay awake longer than 5 min Why do people dream:

    To satisfy our own wishes – in large this theory has given way to many others To file away memories – help sift, sort and fix the days memories in our memory To develop and preserve neural pathways

    To make sense of neural static – dreams erupt from neural activity spreading upwards from the brainstem To reflect cognitive development – part of brain maturation Hypnosis
    Biological and psychological explanations of behavior are partners, not competitors Hypnosis can help people get over stress related ailments and help cope with pain/fear 3 myths associated with addiction

    Addictive drugs quickly corrupt – morphine taken to control pain is powerfully addictive and often leads to heroin abuse (about 10% of people have difficulty using psychoactive drugs in moderation or stopping all together) Addictions cannot be overcome voluntarily; therapy is required – recovery rates of treated and untreated groups barley differ – viewing addiction as a disease can undermine self-confidence and the will to change cravings We can extend the concept of addiction to cover not just drug dependencies, but a whole spectrum of repetitive, pleasure-seeking behaviors 3 major categories of psychoactive drugs

    Depressants – alcohol, barbiturates, opiates
    Stimulants – caffeine, nicotine, cocaine, amphetamines, ecstasy Hallucinogens – LSD, MDMA, marijuana
    Psychoactive drugs effects depend on the dosage, the form ingested, the situation and the users expectations and personality LSD and other powerful hallucinogens are chemically similar to (and therefore block the actions of) a subtype of the neurotransmitter serotonin Why adolescents become regular drug users

    Thrill seeking
    Biological influences – genetic predispositions – variations in neurotransmitter systems Psychological influences – lacking sense of purpose, significant stress, psychological disorders (depression) Social-culture influences – urban environment, cultural attitude toward drug use, peer influences Suggestions for drug prevention and treatment programs

    Educate young people about the long-term costs of a drugs temporary pleasure Help young people find other ways to boost their self-esteem and purpose in
    life Attempt to modify peer associations or to inoculate youths agains peer pressures by training them in refusal skills People rarely abuse drugs if they understand the physical and psychological costs, feel good about themselves and the direction their lives are taking and are in a peer group that disapproves of using drugs
