Midterm 1 Flashcards
affective forecasting
can be difficult
predicting future emotional states
EEG testing
method of fast testing
predicting future emotional states
bad because there’s a lot of stuff in the way
neuroscience
is good to make things sound more reliable
people will buy into it more
2x2
two independent variables
4 levels
4x2x2
three independent variables
16 levels
operational definition
statement of procedures, variables used to define research
rem sleep
when ppl r dreaming
Cat scan
good structural resolution
exposure to x rays
Imaging
CAT, multiple x rays
PET
MRI
PET
advantage to see brain in action/motion/function
like a pet is like moving so its like action
but slow, so like some pets get slow too
MRI
magnetic af
neuroscience good for
what individuals won’t tell you, social desirability concerns
wat they won’t tell you/unaware
Primary Motor projection area

wernicke temporal
cant produce intelligble language
visual cortex
recieves written words as visual simulation
angular gyrus
transforms visual representations into an auditory code
motor cortex
word is pronounced
broca’s area
controls speech muscles via motor cortex
wernicke’s area
interprets auditory code

influence pain/pleasure, feel after a workout, acupuncture, runner’s high
encorrer like run like pain
Serotonin

amygdala
fear and stress
brain surgery, uncontrollable seizures
split corups callosum
- carries brain signals between two halves
right handed people
oral speech in left hemisphere
dendrites
recieve nerves from other and send the signals
Axon

myselin sheath
makes nueron signal more efficient
the journey
presympatic to postsynaptic
take signal then used again
conciousness
subjective awareness of ourselves and our environment
inattentional blindness
