Cognitive Neuroscience
|
study of the brain linked with cognition (including perception, thinking, memory, language)
|
|
|
|
Selective Attention
|
focusing of conscious awareness on a particular stimulus
|
can cause accidents (driving & talking on the phone)
|
|
|
Selective Inattention
|
so focused you don't notice something else happening else happening
|
|
|
|
Inattentional Blindness
|
failure to see visible object when your attention is directed somewhere else
|
|
|
|
Choice Blindness
|
failure to notice changes in the environment
|
you're so involved with giving someone directions that you don't notice another person has stepped in their place
|
|
|
Dual Processing
|
info is often simultaneously processed on separate conscious & unconscious tracks
|
we know more than we think we know
|
|
|
consciousness
|
our awareness of ourself & the environment
|
|
|
|
Stage 1
|
hallucinations/ memories
|
|
|
|
Stage 2
|
burst of rapid brain wave activity/ sleeptalking
|
|
|
|
Stage 3
|
deep sleep (delta waves)
|
|
|
|
Stage 4
|
sleepwalking (delta waves)
|
|
|
|
sleep cycle
|
1 2 3 4 3 2 REM 1
|
|
|
|
REM sleep
|
start dreaming/ muscles relax ( rapid eye movement, irregular brain waves, heart rate raises)
|
|
|
|
what if we didn't dream?
|
•get dumber
•immune system would go down •trouble w/ mental processing •higher thinkong level goes down |
|
|
|
why do we sleep?
|
•helps sustain better moods
•preform more efficiently •increase concentration •moderates hunger |
|
|
|
what if we didn't sleep enough?
|
difficulty studying, diminishes productivity, make mistakes, irritability, fatique
|
|
|
|
sleep debt
|
slowed performance, impaired creativity, concentration & communication, reaction time slows
|
|
|
|
insomnia
|
inability to sleep
|
mom
|

|
|
what do we dream?
|
•8/10 dreams marked by negative events or emotions
•noises can be weaved into dreams •even in REM sleep we are aware of changes in our external environment |
|
|
|
REM rebound
|
increased REM sleep (like double time dreams)
|
|
|
|
why do we dream?
|
to file away memories and preserve neural pathways
|
|
|
|
Freud's wishful fillment
|
dreams may have a hidden meaning
|
|
|
|
manifest content
|
bear=bear
|
|
|
|
latent content
|
metaphor- bear= something else
|
|
|
|
information-processing
|
sort of days & consolidate memories
|
|
|
|
physiological function
|
REM may help develop & preserve neural pathways
|
|
|
|
Activation-Synthesis
|
REM sleep triggers random memories, which can weave into our dreams
|
|
|
|
Cognitive development
|
reflects your knowledge & understanding
|
|
|
|
social influence

|
|
dependence
|
stop using & u can't fuction "normally" w/o it & u start to crave it
|
|
|
|
depressants
|
alcohol & opiates dampen neural activity & slow body function
|
|
|
|
stimulants
|
caffeine, nicotine, cocaine; excite neural activity & speed up body functions
|
|
|
|
hallucinogens
|
marijuana- distort perception & evoke hallucinations- relaxation, impair motor coordination &reaction time & disrupt memory
|
|
|
|
what do depressants do?
|
slow nervous system, impairs judgment, suppresses REM sleep- disrupts memories & reduces self awareness
|
