States of consciousness
|
Sleeping, waking, daydreaming,

|
|
Cognitive neuroscience
|
Study of the brain activity linked with our mental processes
|
|
|
Dual processing
|
The principle that info is often simultaneously processed on separate conscious and unconscious tracks
|
|
|
Blindsight
|
A condition in which a person can respond to a visual stimulus without consciously experiencing it
|
|
|
Visual perception track
|
Enables us to think about the world- recognize things and to plan the future actions

|
|
Visual action track
|
Guides our moment to moment movements

|
|
Selective attention
|
the focusing of conscious awareness on a particular stimulus
|
|
|
Cocktail party effect

Inattentional blindness
|
Failing to see visible objects when our attention is directed elsewhere
|
|
|
Change blindness
|
Failing to notice changes in the environment
|
|
|
Choice blindness
|
We dont choose to attend to these stimuli; they draw our eye and demand our attention
|
|
|
Circadian rhythm
|
Our internal biological clock; regular bodily rhythms
|
|
|
REM sleep
|
(Rapid eye movement sleep) aka: paradoxical sleep
|
|
|
Alpha waves
|
The relatively slow brain waves of a relaxed, awake state
|
|
|
Hallucinations
|
False sensory experiences, such as seeing something in the absence of an external visual stimulus
|
|
|
Delta waves
|
The large slow brain waves and associates with deep sleep
|
|
|
NREM
|
Non rapid eye movement
|
|
|
Sleep theories:
|
•sleep protects
•sleep helps us recuperate •sleep helps restore and rebuild our fading memories of the days experiences •sleep feeds creative thinking •sleep support growth |
|
|
Insomnia
|
Reoccurring problems in falling or staying asleep
|
|
|
Narcolepsy
|
A sleep disorder characterized by uncontrollable sleep attacks. The suffer may lapse directly into REM sleep, often at inopportune times
|
|
|
Sleep apnea
|
When a person stops breathing in the middle of the night and wakes up just enough to start again
|
|
|
Neural activation
|
REM sleep triggers neural activity the evokes random visual memories, which our sleeping brain weaves into stories
|
|
|
Cognitive development
|
Dream content reflects dreamers cognitive development- their knowledge and understanding
|
|
|
REM Rebound
|
The tendency for REM sleep to increase following REM sleep deprivation
|
|
|
Hypnosis
|
A social interaction in which one person (the hypnotist) suggests to another (the subject) that certain perceptions feelings thoughts or behaviors will spontaneously occur
|
|
|
Posthypnotic suggestions
|
A suggestion made during a hypnosis session
|
|
|
Dissociation
|
A split in consciousness, which allows some thoughts and behaviors to occur simultaneously with others
|
|
|
Night terrors
|
Nightmares when the the person suffering isnt it REM sleep and therefore has real life symptoms
|
|
|
REM dreams
|
"Hallucinations of the sleeping mind" - are vivid, emotional, and bizarre
|
|
|
Dreams can consist of:
|
•repeatedly failing, being attacked, pursued or rejected or experiencing misfortune
|
|
|
Manifest content
|
The remembered story lime of a dream
|
|
|
Latent content
|
The underlying meaning of a dream
|
|
|
Theories of why we dream:
|
•to satisfy our own wishes
•to file away memories •to develop and preserve neutral pathways •to make sense of neural static •to reflect cognitive development |
|
|
Freud's wish- fulfillment
|
Dreams provide a "psychic safety valve"
|
|
|
Information processing
|
Dreams help us sort out the day's events and consolidate our memories
|
|
|
Physiological function
|
Regular brain stimulation from REM sleep may help develop and preserve neural pathways
|
|
|
Psychoactive drugs
|
Chemicals that change perceptions and moods
|
|
|
Depressants
|
Calm neural activity and slow body functions
|
|
|
Barbiturate drugs; aka: tranquilizers
|
Depressed nervous system activity
|
|
|
Opiates
|
(Opium, morphine and heroin) depress neural functioning
|
|
|
Stimulant
|
Excites neural activity and speeds up body functions
|
