Theoretical perspectives (chapter 2) Flashcards
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
Psychodynamic model weaknesses
- pretty abstract
- difficult to explain
- difficult to measure
- interpretation can be wrong
- no empirical support
- outdated
Humanistic model
-focuses on the belief that people are basically good and strive for growth and fulfillment, personal responsibility, living in the here and now and personal growth.
Abraham Maslow
Believed we work to satisfy basic and higher order needs and established a hiararchy pyramid.
Self actualization
Development of a person’s full potential
Actualized tendency
-we are all born with a motivation to grow into a better person and reach our full potential.
Organismic valuing process
-we select our goals based on internal values of experiences.
Self congruence
Symbolized experiences actual fit your actual experiences and values(who I am and who I want to be).
Existential living
Mindfulness
Organismic trust
Trust ones own experiences and not bound by others’ opinions
Experiential freedom
Assumes responsibility for decisions and behaivor
Humanistic model strengths
- fosters responsibly for patient’s recovery
- avoid dwelling on the past
- much more optimistic outlook for patients
Humanistic model weaknesses
- abstract
- difficult to explain to patients
- lacks scientific support
- can’t be tested
- select group of people who it can be effective for(can’t let a child run a therapy session).
