Week 9: Psychopathology 1
-It is often hard to define what makes behavior abnormal (differ in culture, time
period, people)
fixed set of criteria to broadly define abnormalities “4 D’s”
1. Deviance
*** only guidelines refers to having thoughts, emotions and behaviors that
not necessarily label fall far outside the standards of what others are doing
someone as having
psychological disorder also includes those who fall well below and well above
the standard of group
*no single D alone can 2. Distress
diagnose psychological person experiences intense negative feelings due to
disorder their behavior (anxiety, sadness, despair)
exceptions: -bipolar patients in manic phase(extremely
elated and larger than life)
-antisocial patients (no remorse or distress)
3. Dysfunction
Behavior tends to interfere with persons ability to
function properly in daily lives.
Can not longer go to work & earn living, or run
household.
Often “maladaptive” behaviors => prevent individual
adapting to environment.
4. Danger
Danger to oneself or another
Person engaging in risky behavior, lead to drug
addiction
Person engages in violence towards others
Some engage in risky behaviors everyday
Extreme sports, office workers with bad food + no
exercise
-Normal vs abnormal not clear-cut, need to properly diagnose/classify disorder
using guidelines from a book called; Diagnostic and Statistical Manuel, aka DSM.
-DSM has 2 main functions; provides standardized criteria to aid in diagnosis
1) Categorizes & describes mental disorders clinicians have
common set of criteria for applying diagnostic label to symptoms of
patients.
2) Allows researchers to talk about mental disorders using common
language -DSM as 2 main criteria; must be met before diagnosis, regardless of disorder
1) Disordered behavior must originate within the person, not as a
reaction to external factors (ex, person crying uncontrollably-
depression vs. lost family in car accident)
2) Disordered behavior must be involuntary, and person is unable
to control symptoms (rules out: person dressed up for football game,
or person on hunger strike for protest)
-DSM attempts to group similar disorders together (assumption that similarities
suggest common cause & can be similarly treated)
->but….some things change (researchers discover new information)
-->leads to…..changes in criteria for diagnosis & groupings of disorders
--->thus……new version of DSM is released
-DSM…ONLY describes pattern of symptoms
DOES NOT offer explanation for disorder or suggest treatment
-BUT having label for set of abnormal behaviors only helpful if an explanation or
treatment plan (DSM doesn’t have this)
SO…turn to models of psychopathology=> attempt to explain
causes/treatments
-4 main models of psychopathology
1. Biological
Aka medical/disease model
Assumes psychological disorder result from malfunction in brain
Causes: physically damaged OR abnormal activity of chemicals in
brain; neurotransmitters
Points^^: genetics, nutrition, disease, stress
Medical & Treatment: drugs, electroconvulsive shock/ brain surgery (extreme
psychodynamic cases)
agree mental 2. Psychodynamic
disorder is Earliest model
internal problem.
Disordered & Pioneered by Freud
maladaptive Believes mental disorder is rooted in internal malfunction (like
behaviors on biological)
outside, are But… instead of physical, thought to be psychological malfunction
symptoms of
internal problem It is mind and processes….NOT physical brain not working properly
Attributed to maladaptive attempts to deal with strong, unconscious
conflicts, => Freud believe conflicts stem from unresolved childhood
issues
Treatment: no physical therapy (can only alleviate symptoms)
Only psychological therapy; treatment must focus on
therapy to cope with underlying stressors
3. Behavioral
Disordered behaviors & emotions symptoms on internal problem,
instead behaviors/emotions are problem (external)
Suggests depression arises in individuals lacking social skills (make it difficult to elicit normal positive social
reinforcement from others)…may lead to lowered mood, self-blame of depression. But…depressive symptoms
may elicit sympathy, attention, concern=> lead to reinforcement of symptoms Views psychological disorders as external, overt behavior rather than
an internal malfunction
Argue that… disordered behaviors established through classical &
instrumental conditioning.
Contingencies, rewards, punishments=> received for actions=
influence behavior
Attempt to…treat maladaptive principles from conditioning (ex.
Classical conditioning treats phobias)
People may find that disordered behavior provides “rewarding”
attention from others
Down sides: #1 can you really say someone who hears & responds
to voices in their head has learned to behave that way?
#2although treatment is often effective while inside
therapist office, it does not always transfer well to other
environments.
#3criticized for treating people as simple reflective
beings that just react to environment, rather than
having ability to plan, remember, & predict things in
world.
Some ^ criticisms addressed by cognitive model.*
Theory: -learned from helplessness
-assumes depressive symptoms result from sense of helplessness
about situation which subject learns to withhold responding.
-inspired from animal research (1-dogs exposed to inescapable, mild
electrical shocks… first dogs try to escape then accept
circumstances. 2-when shocks avoidable, most continued to be
passive)
4. Cognitive
Suggests mental disorder result from maladaptive/inappropriate
ways of selecting/interpreting information from environment.
Psychological disorders may be due to maladaptive, negative
interpretations of life events
Ex; anxious/depressed not because of what is happening around, but
because of way of interpreting those events (ie; public
speaking=>how you interpret a situation affects your response)
Assumes…experience & learning play important role in shaping
maladaptive thinking.
Therapies… designed to identify maladaptive thinking, & change to
positive experiences Behavioral & cognitive approaches to therapy complement each other,
therapies combine both thinking & behavior (aka cognitive-behavioral
therapies CBT)
o Cognitive therapy focuses on positive interpretations of situations
o Behavior therapy focuses on seeking out positive situations & actions
Mood disorders: characterized by disturbances in emotion, includes
depressed mood of depression & elevated mood of mania.
2 main types of depressed mood disorders
1. Unipolar Depression (aka Major Depression)
