exam 1 Flashcards
operation definition
the unit of measurement and the actions you’re taking in your experiment
different types of bias
sampling bias, placebo, experimenter bias, responses bias
sampling bias
the sample you take being biased
placebo effect
people thinking they are being treated and having symptoms resolved due to their brain thinking
experimenter bias
the experimenter observing that the patients they are treating are doing better than the others because they want them to be doing better (solved by double blind)
responses bias
people being misled to answer questions untruthfully based on different factors (social pressure, etc.)
soma
the cell body, holds the chemicals to make reactions,
axon
thin fiber that transmits signals away from the soma to the axon terminals
axon terminals
what axons end in. they secrete chemicals called neurotransmitters
myelin sheath
insulation for the axon which helps with conductivity and protection
action potential
a very brief charge that travels along the axon carrying information
synaptic transmission
a reaction that releases neurotransmitters into receivers of the next dendrites in line with the neurons
acetylcholine (ACh)
controls muscles, hearts, and lungs
dopamine (DA)
feel good drug, emotional regulation, and voluntary movements.
serotonin
regulates sleep and wakefullness and mood.
endorphins
naturally occurring painkillers, increase dopamine which makes us feel good
brainstem
controls the flow of messages between brain and the body
cerebellum
keeps body balanced (affected by alcohol)
phineas gage
dude with pole through his frontal lobe whose personality changed
right hemisphere
visual and facial recognition
corpus callosum
connects two hemispheres
left hemisphere
language
parts of the eye
cornea, pupil, iris, lens, retina
rods
part of the retina that is for seeing black and white and daytime, much more of them and less specialized
cones
part of retina that is used for seeing in color, more specialized, less of them
four lobes of cerebrum
frontal, parietal, temporal, and occipital lobe
frontal lobe
decision making. high level cognition, executive functioning, working memory,, and emotion regulation. not developed until 25
parietal lobe
perception of environment, perceives all 5 senses, math and science, tells cerebellum about environment. math and spacial skills
temporal lobe
hearing, language comprehension
occipital lobe
visual center for brain
optic chiasm
separates information from each visual field including the outer part of the eye
bottom up processing
detect specific features of stimulus- combine features into forms - put forms together into stimulus
top down processing
detect stimulus as a whole; form a hypothesis about what it is, examine features to check hypothesis, recognize stimulus (requires familiarity)
what neurotransmitter affects Parkinsons/ what happens
dopamine, the dopamine neurons that generate dopamine die and people aren’t sure why.
zoloft and prozac affects what neurotransmitter/ how?
serotonin. prozac and zoloft block the reuptake of the serotonin so that it is all used instead of being recycled
