PSY 352 UPDATED EXAMS SCRIPT TIPS
QUESTIONS AND ANSWERS SURE A+
✔✔Rosenhan's "On being sane in insane places" - ✔✔-Demonstrates the perils of
pretending to have psychotic symptoms
-Be careful of how your expectations may influence your perceptions of behavior
-important to be aware of our own cultural biases
✔✔Biological Models - ✔✔-Medical models
-structural brain models
-neurochemical and endocrine models
-genetic models
✔✔Biology - ✔✔Biology influences behavior and vice versa
Ex: CBT has same affects on brain as psychiatric medication
Ex: testosterone levels vary by sexual activity
*Dualistic divisions of mind and body are not useful here
✔✔The Neuron - ✔✔1. Dendrites
2. Cell Body
3. Axon
4. Myelin Sheath
5. Terminal branches of axon
, *Each neuron only makes one type of neurotransmitter
✔✔dendrites - ✔✔receive messages from other cells
✔✔Axon - ✔✔Passes messages away from cell body to other neurons
✔✔Myelin Sheath - ✔✔Covers the axon of some neurons and helps speed up neural
impulses
✔✔terminal branches of axon - ✔✔Form junctions with other cells
✔✔Synapse - ✔✔A junction between the axon tip of the sending neuron and the
dendrite of the receiving neuron
1 Billion in one speck of brain
✔✔Action potential - ✔✔Electrical impulses that travel across the synapse
*All or nothing process
-when the neuron fires, it releases a neurotransmitter that travels across the synapse
and binds to receptor sites of the receiving neuron
✔✔Reuptake - ✔✔Neurotransmitters in the synapse are reabsorbed into the SENDING
neurons through the process of reuptake. This process applies the brakes on
transmitters
*SSRIs (some antidepressants) increase available serotonin levels by preventing
reuptake of serotonin.
✔✔Lock and Key Mechanism - ✔✔The receptor site on the receiving neuron is very
specialized to the neurotransmitter. Neurotransmitter precisely fits the receptor site
✔✔Neural Networks - ✔✔Interconnected neurons form networks in the brain. These
networks can be modifies with growth and experiences.
-create new pathways when you learn
-each neurotransmitter has independent neural pathways
✔✔Serotonin - ✔✔Involved in mood regulation
✔✔Dopamine - ✔✔Involved with Schizophrenia (excess) and Parkinson's disease
✔✔The Hormonal (endocrine) System - ✔✔The body's slow chemical communication
system
-Hormones are CREATED by glands and secreted in the bloodstream
-affect the brain and many other tissues
✔✔Hypothalamus - ✔✔Brain region controlling the pituitary gland (master gland).
