chapter 2 and 3 FINAL Flashcards
a independent variable is to have ____
change
a dependent variable is to have _____
measure
what is a cofound
occurs when tow variables are linked together in a way that makes it difficult to sort out their specific effects
what is a single-blind study
subject doesnt know if they are getting the real therapy or not
what is a double blind study
neither the participant or the examiner know which subjects are in the experiment or control group
what is naturalistic observation
behavior that is allowed to unfold naturally without interferience in its natural enviroment, reactivity could be a problem when a subjects behavior is altered by the presence of an observer
when two variables are related to each other
correlation
degree of relationship between two variables-direction of relationship (pos or negative), how strong they are related,
correlation coefficient
when two variables vary in the same direction
high scores on a X are associated with high scores on Y
positive correlation
two variables are vary in opposite directions (high scores on X score low on Y and vice versa)
negative correlation
cell body, contains nucleus and chemical machinery
soma
recieves the info
dendrite
sends signals away from the soma to other neurons, muscles or glands
axon
what is a terminal button
secrete neurotrasnsmitters (transmit between neurons)
function of synapse
junction where info is transmitted from one neuron to another
provides support for the neurons (glue)
gilia
what is composed in the hindbrain
cerebellum, medulla, pons
controls coordination, physical balance, muscle movements
cerebellum
what is the function of the medulla
controls unconscious but vital functions (blood, breathing, muscle tension, etc)
controls sleep and arousal, bridge fibers to connect brainsteam and cerebellum
pons
sensory process (hearing and vision), dopamine-releasing neuron (voluntary movement)
midbrain
what is composed of in the forebrain
thalamus, hypothalamus, limbic system, cerebrum
what is the cerebrum function
center of complex thoughts learning, remembering things, thinking, conscious self
function of thalamus
all sensory info except smell, made of somas
function of hypothalamus
regulates basic needs fighting, fleeing, feeding, and mating
involves emotional, memory and motivation
limbic system
in charge of the memory
hippocampus
in charge of fear responses
amygdala
in charge of visual processing (primary visual cortex)
occipital lobe
in charge of the sense of touch
parietal lobe
in charge of auditory processing, damage effects speech and language
temporal lobe
largest movement of muscles (primary motor cortex)
frontal lobe
in charge of moving
precentral
in charge of pain
postcentral
