Theoretical perspectives (chapter 2) Flashcards
(91 cards)
Biological model
Focuses on physical factors accounting for mental illness
Somatic marker hypothesis
Emotions guide decision making by maxamizing good outcomes, minimizing bad outcomes and focusing on what is important
Capgras syndrome
People recognize important person in one’s life but fail to elicit emotional response.
-may believe person is a copy or corrupted or otherwise changed
EEG(electroencephalography)
Measures general brain activity but not a lot of specificity.
CT scan
Judges activity in specific locations via bloodflow
PET scan
Using a radioactive dye, or tracer in the blood which decays in a different rate depending on activity levels in certain brain regions
MRI(Magnetic resonance imaging)
Magnetic pulses generated by oxygen in the blood
fMRI
Looks at changing in blood flow to determine where activity is or is not happening int he brain.
Seratonin
Processing of information, regulation of mood, behaivor and thought processes
Norepenephrine
Regulation of arousal, mood, behaivor and sleep
Dopamine
Influences novelty seeking, pleasure, motivation, coordination, moter movements and sociability
GABA
Regulation of mood, especially anxiety, arousal and behaivor
Acetylcholine
Important in moter behaivor, arousal, attention, reward, learning and behaivor
Glutamate
Influences learning and memory
Biological Model strengths
Provides some answers and clear connections between brain structure and mental illness:
- NT’s
- brain
- genetics
- easier to pinpoint what is causing the problem
- tested empirically
Biological Model weaknesses
• Mutations in genes that are not in your family
-environment
-personal reaction
-amount of help a person is receiving
-lacks information on culture, family, and stress present
(Doesn’t cover the whole picture)
-we don’t really know HOW we just know they are connected
Psychodynamic model/perspective
Focuses on internal personality characteristics and Freudian theory(assumes mental states and behaivors arise from motives and conflicts within a person.)
—causes and purposes of human behaivor are not always obvious but partly unconscious
-people use defense mechanisms to control anxiety
Psychic determinism
The belif that everything we think, feel, and do has meaning and is worth looking into.
Id
Attempts to obtain gratification of wants, needs, impulses and primary process form of thinking
Pleasure principle
The id’s desire to seek pleasure and avoid pain in any way possible
Superego
-blocks the id’s impulses, and is a storehouse of values adopted from environment.
Ego
Mediates between the Id and super ego.
-uses secondary process form of thinking
Reality principle
Seek pleasure and avoid pain in socially acceptable ways
Psychodynamic model strengths
- focuses on childhood and how it can shape your future
- widely accessible
