conciousness
all sensations and perceptions incoorperoted
split brain
- copus cut
- left brain for language right for spatial awareness
- explain diagram
parts of conciousness (5)
- content of conciousness
- subjective expeirneces of ext and int world
- most brains functions beyons awareness (medulla homeostasis)
- states of conciousness
- arousal and attention, being aware of information
ex:
-spontaneous ,
-physiological,
-psychological,
-drug induced (name examples)
Attention
process of selecting what to prioritize from vast amount of info coming in at any time
or (“The internal process that selectively sets mental priorities for processing”)
depends on
- attention captivated/noticed depends on goals experiences and state of mind of individual (finding freind in crowsd)
passive attention
- bottom up, sometimes automactic
active attention
- top down: driven by goals
- searching for keys on a clustered table
selective attention and stimulus salience
- attend to one source of infor while simultaneously ignroing another stimuli (bright light in dim scene)
- stimulus salience: low level bottom up qualities of a scene that infleunce how we direct attention
- means your attention has been CAPTURED (divereted from elesewhere and focused on soemthing)
- stimulus slainece could be yellow flower on black background
role of topp down process in attention
how selective attention is guided
of you watch a lot of football your better at noticing changes on the field, and where to focus your attention
the cocktail effect and dichotic listeing task
- with selective attention. at a party person can be talking and suppress ignore all info going on around them to attend to convo
not all info blocked (if someone called your name out across the room youd turn)
- dichotic listeing task (1950): proved that specific kinds of unattended information are processed and can later be recalled (gender of speaker)
divided attention
- simultaneously attened to two or more tasks at the same time
- not good at this
expeirice can increase multitasking (only when one task is automatic) like listeing to music and typing)
-autoamitic (performance not hindered by other tasks
- not all automatic behaviours are equal (predictablity plus consequences can vary)
-driving: driving is automatic
inattentional blindness + inhibition
brain does inhibition. actively reducing processing of some information while brain attends to specific task
basketball passing video
miss gorrilla, no idea how many passes
flicker task
chnage blindness and change detection (give examples)
subconcious vs subliminal processing + give examples
subconcious
-info were aware of, but not aware that it infuenced our behaviour
subliminal
- stimulus that is processed but ont conciously detected even if were looking for it (messages presented to quick for VS to perceive)
visual neglect
ADHA
what is sleep
how is sleep measured?
EEG EOG EMG
Stages of sleep (alpha, beta, stage 1, stage 2, sws)
Rem vs non rem sleep
hypnogram (explain graph)
Rem and dreams
two theories about why we sleep
functions of SWS and REm sleep
freud and dreams/sleep and problems with dream analysis
-psycholansis
intepreattion of dreams
took it to far
