case study
study individual in great depth to reveal universal truths
substance administered without the drug in it
-looks inward (introspective)
-Edward Titchner
-how we interact w/ eachother
-why we do the things we do
double-blind procedure
experimental procedure where both participants and researchers are blind as to who received the treatment or placebo
placebo effect
any effect on behavior caused by the placebo
experimental condition
people who receive the treatment
control condition
w/o treatment for comparison
random assignment
assigning participants by chance, minimizing pre-exhisting differences between the assigned different groups
independant variable
factor that is being manipulated
dependent variable
experimental factor that is being effected
corralation coefficient
how much things vary/to what degree (relationships)
neuroscience perspective
how the body and brain enable emotions, memories, and sensory experiences
evolutionary perspective
how the natural selection of traits promotes the perpetuation of one's genes
behavior genetics perspective
how much of our genes ad our environment influence our individual differences
psychodynamic perspective
how behavior springs from unconscious drives and conflicts
behavioral perspective
how we learn observable responses
cognitive perspective
how we encode, process, store, and retrieve information
social-cultural perspective
how behavior and thinking vary across situations and cultures
the view that knowledge comes from experience via the senses and science flourishes through observation and experimentation
a nerve cell; the basic building block of the nervous system
the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell
the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons, muscles or glands
action potential
a neural impulse; a breif electrical charge that travels down an axon
myeliln sheath
-layer of fatty tissue encasing the axons
-helps speed neural impulses
the level of stimulation required to trigger a neural impulse
the junction between the axon tip of the sending neuron and the dendrite/cell body of the receiving neuron
chemical messengers that move thru the synaptic gaps between neurons
controls self-regulated actions of internal organs and glands
natural neurotransmitters linked to pain and pleasure
controls the movements of our skeletal muscles
-base of brain
-begins from spinal cord
-runs from brainstem
-controls heartbeat and breathing
reticular formation
-above medulla
-controls arousal
-above reticular formation
-reeives information from all senses except smell and routes it to the higher brain region
checks for electrial symptoms
-swallow radioactive fluid
-visual display of brain activity
-uses magnetic fields and radio waves to produce images that distinguish different types of soft tissue
-allows us to see structures w/in the brain
-impaired use of language
-some can speak fluently but not read
Broca's area
-controls language expression
-after damage, a person struggles to form words yet can sing familiar songs easily
Wernicke's area
-controls language reception
-after damage, people could only speak meaningless words and were unable to comprehend other people's words
processes memory
pituitary gland
secretes different hormones
maintenence regulator (eating, drinking, body temp)
the brains capacity for modification, as evident in brain reorganization following damage and in experiments on the effects of experience on brain development
frontal lobes
-portion of the cerebral cortex lying just behind the forehead
-involved in speaking and muscle movements and in making plans and judgments
parietal lobes
the portion of the cerebral cortex lying at the top of the head and toward the rear
occipital lobes
-the portion of the cerebral cortex lying at the back of the head
-includes the visual areas, which receive visual info from the opposite visual field
temporal lobes
-the portion of the cerebral cortex lying roughly above the ears
-includes auditory areas, each of chich receives auditory info primarily from the opposite ear
motor cortex
an area at the rear of the frontal lobes that controls voluntary movements
sensory cortex
the area at the front of the parietal lobes that registers and proesses body sensations
adrenal glands
a pair of endocrine glands that secrete the hormones epinepherine and nonepinepherin, which help to arouse the body in times of stress
pituitary gland
the endocrine systems most influential gland that regulates growth and controls other endocrine glands
Function of ACh
enables muscle action, learning and memory
Function of Dopamine
influences movement, learning, attention, and emotion
Function of Serotonin
affects mood, hunger, sleep, and arousal
Function of norepinepherine
helps control alertness and arousal
Function of GABA
a major inhibitory neurotransmitter
Function of Glutamate
-a major excitatory neurotransmitter
-involved in memory
