- 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
