What are the 2 types of behavior and what are their characteristics?
|
overt- readily observed
covert- mental processes |
|
What three things link to make psychology?
|
physiology, behavior, environment
|
|
Explain introspection
|
observers report moment-to-moment reactions, or self-reported.
|
|
Why was introspection eventually dismissed and what replaced it? Explain this concept.
|
introspection couldn't be verified. Behaviorists- only overt behavior belongs in science
|
|
What last change in psychology gave rise to the complete view we have today?
|
realization that the method, not material of covert studies was flawed. these people are known as cognitive psychologists.
|
|
When is an experiment an effective research method?
|
cause & effect between 2 variables.
|
|
What's the difference between a between subject design and an within subject design?
|
between subject design- 2 groups of subjects get 2 different manimulations
w/in subject design- 1 group of subjects & all exposed to same conditions |
|
What are the characteristics of a correlational study?
|
finds relations between conditions; observes, doesn't test; doesn't show what causes what
|
|
What are the 2 parts of the nervous system?
|
central and peripheral
|
|
What are the parts of the central nervous system?
|
brain and spinal cord
|
|
What are the 2 parts of the peripheral nervous system and what do they do?
|
somatic- sensory organs to CNS and CNS to skeletal muscles
autonomic- involuntary movements |
|
What are the 2 divisions of the autonomic part of the PNS and explain?
|
sympathetic- arousing
parasympathetic- calming |
|
What are the 3 types of neurons and what do they do?
|
sensory- signals from senses to CNS
motor- signals from CNS to muscles, glands, organs inter- link input and output |
|
What is the function of glial cells?
|
structural support and insulation for neurons.
|
|
Name the parts of the neuron through which pulses will go in order.
|
dendrites, soma, axon/myelin sheath, axon terminals/terminal buttons/presynaptic terminals
|
|
Name 3 methods of brain imaging
|
EEG, CT scan, PET scan, MRI, fMRI
|
|
Explain the EEG
|
records brain waves. Can diagnose tumors, strokes, and infections
|
|
Explain the CT scan
|
x-ray beams
horizontal cross-section of brain |
|
Explain the PET scan
|
measures brain activity by measureing glucose levels. good for determining which parts of the brain are in use during certain activities.
|
|
Explain the MRI
|
magnetic field gives brain image
|
|
Explain the 2 types of brain messages
|
electical- w/ in neurons, action potential created by ions
chemical- neurotransmitters released in synapse. vesicles bursted by action potential |
|
The orientation of the spinal cord has an effect on function. Which side is responsible for what?
|
dorsal- input
ventral- output |
|
What are the parts of the Hindbrain?
|
Medulla, Pons, Cerebellum
|
|
What are the parts of the Midbrain?
|
Tectum, Tegmentum
|
|
What are the parts of the Forebrain?
|
Limbic System, Thalamus, Hypothalamus, Cerebral Cortex
|
|
Name the 4 lobes of the cerebral cortex.
|
Occipital lobe, parietal lobe, temporal lobe, frontal lobe
|
|
What's the function of the medulla?
|
regulating vital functions
|
|
What's the function of the pons?
|
sleeping and dreaming
|
|
What's the function of the cerebellum?
|
coordinated movements
|
|
Tectum function?
|
processes visual and auditry info
|
|
tegmentum function?
|
sleep and arousal, pain perception, intiating movement
|
|
limbic system function?
|
learning, memory, emotions
|
|
thalamus function?
|
"way station" of sensory function
|
|
hypothalamus function?
|
endocrine system
|
|
occipital lobe characteristics?
|
posterior end of cortex
visual cortex |
|
parietal lobe characteristics?
|
above occipital lobe
somatosensory cortex (ie touch) |
|
temporal lobe characteristics?
|
behind temples
auditory cortex complex visual analysis |
|
frontal lobe characteristics?
|
front of cortex
motor cortex fine movement control |
|
What are ventricles?
|
connected cavities w/in CNS
resoviour of hormones bouyancy to brain |
|
What are the centers for language?
|
Broca's area- output
Wernicke's area- input |
|
What's the corpus callosum?
|
Connects 2 brain hemispheres
|
