Chapter 15: Psychopathology
Where is the line between “normal” and “abnormal?”
Normal | Abnormal |
|
Examples of “abnormal” behavior
Professor who sings his lectures
Walking on your hands instead of feet
Person arguing with themself
Counting each step you take each day
Eating only foods with 2 or fewer vowels
Putting 46 bumper stickers on your car
What is “abnormal?”
Statistical Infrequency (Deviant)
Is it rare?
Unusual (outlier)
Schizophrenia =1% (lifetime prevalence)
Personal Discomfort (Distressful)
Does it cause personal suffering?
Abnormality hurts
Impairment (Dysfunctional) **
Does it interfere with functioning?
What are some conceptions of psychopathology?
Contemporary approaches to psychopathology
Medical model
DSM-5-TR (March 2022)
Diagnostic and Statistical Manual of Mental Disorders
Etiology (causes), diagnosis, treatment, prognosis (future)
Categorical vs. Dimensional approaches to diagnosis
Categorical: black or white decision, dichotomous
Light switch that you can switch on and off
5+ out of 9 to qualify for this as a diagnosis
Dimensional: idea that mental disorders have a continuum
Gradual light switch/dimmer
Diathesis-Stress Model of Mental Disorders
NATURE
Diathesis/tendency/predisposition: vulnerability to psychological disorders
Distal causes
Genetic inheritance
Biological processes, such as brain abnormalities or neurotransmitter problems
Nurture
Environmental stressors
Proximate causes
“triggers”
Noxious physical stressors
Relationship/job problems
Trauma, abuse, neglect
Both have the ability to lead to mental disorders
How are mental disorders classified?
Diagnostic and statistical manual of Mental Disorders (DSM-5-TR)
Classifies numerous disorder into categories
Comorbidity: co-occurrence of more than one disorder in the same individual
+2 disorders
Types of disorders
Anxiety Disorders
Substance-related disorders
Mood disorders
Schizophrenia
Personality disorders
ASPD
Never that person's fault
No responsibility
Anxiety Disorders
Disorder | Lifetime Prevalence The percentage of people who meet criteria for a disorder at any time in their lives. |
Generalized Anxiety Disorder (GAD)
| 5% |
Panic Disorder
| 1.5% - 3.5% |
Phobias
| 10% - 11.3% |
Obsessive-Compulsive Disorder (OCD)
| 2.5% |
Post-Traumatic Stress Disorder (PTSD)
| 1% - 14% |
Etiology of Anxiety Disorders
Etiological is causes
Biological Factors
Twin studies suggest a genetic predisposition (diathesis)
Anxiety sensitivity (feedback loop; panic disorder)
Physiological symptoms (sxs. Increased heart rate)
If you have catastrophic thoughts and you think about how bad these thoughts are it causes your heart rate to increase more leading to a spiral.
Neurotransmitters (GABA, serotonin)
Give medication to increase GABA levels like valium or xanax
Learning/Conditioning
Can be acquired through classical conditioning
Can be maintained through operant conditioning
Observational learning may also play a role
Cognitive Factors
Certain ways of thinking may make someone more vulnerable to anxiety disorders
Mood Disorders
Major Depressive Disorder (Unipolar depression)
Lifetime prevalence
Men = 5-12%
Women = 10-25%
Bipolar Disorder (Manic-Depression)
Lifetime prevalence
0.4-1.6%
“Normal” - - - - - - - - - - - - - - - - - - -
Bipolar is a negative sin graph with the lower bubbles being depression and the higher bubbles being MANIA
DSM-5 Symptoms of Depression
Depressed mood most of the day, nearly everyday
Diminished interest in or pleasure in activities
Significant weight loss/gain or decrease/increase in appetite
Insomnia or hypersomnia
Psychomotor agitation or retardation
Fatigue or loss of energy
Feelings of worthlessness or guilt
Diminished ability to think or concentrate
Suicidal thoughts, plans, or actions
Etiology of Mood Disorders
Genetic Vulnerability
Twin studies suggest a strong genetic predisposition (diathesis)
Neurochemical Factors
Norepinephrine
Serotonin levels lower than normal (SSRIs: Prozac, Paxil, Zoloft)
Cognitive Factors
Depressogenic thinking
Beck: cognitive distortions
All-or-nothing, Always or never, Dichotomous thinking
Labeling
Magnification and minimization
Seligman: negative attributional style
Attribution: explanation for why something happened
Negative events drive you towards depression
1.) Internal attributions for the negative events
2.) Global, I suck at everything
3.) Stable, I am gonna do bad at the next thing too
Situational Factors
Life Stressors
Linear relationship between number of stressors and risk of depression
More stressors more depression
Attributional Style and Depression
Symptoms of Schizophrenia
Can be divided into two categories
1) Positive Symptoms - “normal” + pos sxs. = “schizophrenia”
Reflect an excess or distortion of normal functions
Include delusions, hallucinations, disorganized thought and speech, disorganized motor disturbances
Delusions = false beliefs, makes schizophrenia be described as a psychotic disorder
Hallucinations = False sensory experiences (starting to lose touch with reality)
Disorganized thought and speech = Thought disorder
Disorganized motor disturbances = range between catatonic and frenetic
2) Negative Symptoms - “normal” - neg sxs. = “schizophrenia”
Consist of behavior deficits
Include flat affect, alogia, and avolition
Lifetime prevalence = 0.5 - 1%
1% is the figure usually used for schizophrenia
Etiology of Schizophrenia
Genetic Vulnerability (Diathesis)
Twin studies
The more similar you are biologically to someone the more likely you are to develop schizophrenia too.
Neurochemical Factors
Dopamine (levels are too high)
Serotonin
Glutamate
Structural Abnormalities in the Brain
Enlarged ventricles (increased fluid filled cavities which leaves less space for remaining brain volume.)
Smaller than thalamus with less metabolic activity
Thalamus relays sensory information aside from scent
Neurodevelopmental Hypothesis
Disruptions in normal maturational processes of the brain before or at birth
Substance Abuse vs. Dependence
Substance Abuse: significant negative consequences related to substance use
Work, school, home
Use in physically hazardous situations
Legal problems
Continued use despite social/interpersonal problems caused or exacerbated by use
Substance Dependence:
Tolerance
Withdrawal
Larger amounts/longer period than intended
Unsuccessful efforts to cut down
Great deal of time obtaining, using, or recovering from substance
Giving up or reducing important activities
Continued use despite knowledge of physical or psychological problems caused or exacerbated by use
DSM-5-TR Diagnostic Changes
DSM-5-TR basically combines the symptoms lists for substance abuse and substance dependence all into one list
Only two changes have been made
1) recurrent legal problems criterion deleted
2) added “craving or a strong desire or urge to use a substance”
Threshold for substance use disorder diagnosis is now two or more criteria
Childhood Disorders
Attention-Deficit/Hyperactivity Disorder (ADHD)
Prevalence in school-age children = 3-7%
Male:female ratio of 4:1 to 9:1
3 essential features
Inattention: easily distracted
Hyperactivity: Can’t sit still, excessive activity
Impulsivity: Acting without thinking, symptom can cause problems with peer relationships, manifest itself in terms of increased injury
Autism Spectrum Disorder
New category in DSM-5
Prevalence = 1.9%
Onset prior to age 3
Impairments in two domains
1) social communication (verbal and nonverbal) and social interaction (unaware of others)
2) Restricted and repetitive behaviors, interests, and activities
Chapter 16: Treatment of Psychopathology
Biomedical Therapies
Psychosurgery
Brain surgery
Lobotomy (Back in the day)
“Treatment of last resort” for three possible conditions…
1.) Depression
2.) OCD
3.) Chronic Pain
Electroconvulsive Therapy (ECT)
“Shock therapy”
Not so great depictions in TV shows and movies
Refined overtime
Deliver a jolt of electricity to the person’s brain while monitoring their BP, ECG after receiving a muscle sedative
Causes seizures (10-30 sec) which is why the muscle relaxer is needed.
Multiple treatments over a couple weeks
Causes minor retrograde amnesia as a result
It is a successful treatment, don’t know why it works, it’s like a hard reboot for someone with depression (again treatment of last resort)
Repetitive Transcranial Magnetic Stimulation (rTMS)
Less invasive, placing wire coil on top of head and from that wire coil pulses of magnetic energy are applied
Just like the eeg records at the overlining layer the magnetic waves only penetrate the top layer of the brain
2-4 weeks of coming back for treatment
Not knocked out, no retrograde amnesia
Works because it stimulates the left frontal lobe which tends to be inactive in folks with depression
Drug Therapies
Depression
Three major classes of antidepressant medications
1.) Monoamine oxidase inhibitors (MAOIs)
Side effects and some dietary restrictions
Chocolate and red wine
Strange interactions with over the counter medications
2.) Tricyclics
3.) Selective serotonin reuptake inhibitors (SSRIs)
Most common because it affects everyday life the least therefore people will actually take it
Medications stop the removal or reuptake of the neurotransmitter serotonin which leaves more serotonin in the synaptic gap.
May take some time for symptom relief
Marked improvement in up to 60-70% of patients
Types of Psychotherapy
Psychoanalysis (Freud)
(Insight) |--X—------------------------| (Action)
Sigmund Freud
Onsight-oriented treatment
Emphasizes the recovery of unconscious conflicts, motives, and defenses
Goal: “make the unconscious conscious”
Think back to the iceberg, dredge up the unconscious and bring insight to it to help you in the long run
Technique include
Free association: Just think out loud and say whatever comes to mind with no filter
Dream analysis: Manifest content (story), and latent content (interpretation about the story, symbol) no way to disprove theory, not falsifiable
Analysis of Transference: drag and drop scenario, dragging interests, concerns, desires from other contexts
You remind me of my father because of this this and this to be further analyzed
Client-centered Therapy (Rogers)
(Insight) |--—---------X---------------| (Action)
Carl Rogers
Humanistic approach (positive optimistic rather than negative like freud)
Aka “person-centered therapy”
Emphasizes a supportive emotional climate for clients
Clients play a major role in determining the pace and direction of therapy
Philosophy almost
Therapist provides
Empathy: tries to communicate that you understand how they are feeling, and validating feelings
Unconditional positive regard: acceptance, I accept you and I think highly of you
Genuineness: honesty within the moment, share your feelings on what the client just told you.
ACTIVE LISTENING!!
Cognitive Therapy (Beck)
Aaron T. Beck
Emphasizes recognizing and changing negative thoughts and maladaptive beliefs
Utilized with a broad range of disorders
Typically combined with behavioral interventions
Cognitive-Behavioral Therapy (CBT)
Thoughts → Behaviors → Feelings all connected
Treatment is about thinking and behaviors
1.) Catch it
2.) Check it
3.) Change it
Substitute for an alternative thought
The “it” refers to the negative thoughts
Behavior Therapy (Wolpe)
(Insight) |--—----------------------X--| (Action)
Phobias
One form of exposure therapy
Systematic Desensitization
Reduces phobic clients’ anxiety through exposure and counterconditioning
Breaks the connection between the conditioned stimulus (e.g., snakes) and the conditioned response (e.g., anxiety)
Anxiety Response: is replaced with a relaxation conditioned response.
Parasympathetic vs sympathetic
Reciprocal inhibition
1.) Relaxation Training
2.) Construct an anxiety hierarchy
Baby steps to reach no phobia
3.) exposure with relaxation substituted in for anxiety
Relaxation treatment after seeing the trigger
Doesn’t care why you are afraid just wants to help
Exposures counteract the negative reinforcement that results from avoidance
Evaluating Psychotherapy Outcomes
1.) Does psychotherapy work better than no therapy at all?
Is doing something better than doing nothing?
2.) Do some kinds of therapy work better than others?
Is some form better?
Does Psychotherapy Work?
Meta-Analysis: combines the results of many different studies to arrive at an overall conclusion
Conclusion: The average person who receives therapy is better off at the end of it than 80% of persons who don’t receive therapy (control group vs experimental group).
The 80% finding: 80% of untreated people are worse off than the average treated person
DOING SOMETHING IS GENERALLY BETTER THAN DOING NOTHING
Do Some Kinds of Therapy Work better than Others?
Most studies suggest that the various psychotherapies are all about equally effective
Common Factors:
Address emotional situations
Provide interpersonal learning (new perspective)
Offer an empathic, trustong, caring relationship
Specific therapies for specific patients (manualized empirically supported therapies)
Specific Treatment for Specific Disorders
Anxiety Disorders:
Cognitive-behavioral treatments (CBT) are superior
Systematic Desensitization for phobias
CBT for panic disorder (barlow)
Exposure and response prevention for OCD
Depression:
No best way to treat depression
Antidepressants are effective for 60-70 percent of depressed patients
CBT is just as effective as medications
Combination of both bullets listed above is the best treatment.
Schizophrenia
Medication treatments are superior (positive: hallucinations, delusions, thought disorder)
Social skills training is helpful to address social skills deficits associated with schizophrenia
Test #4 Breakdown:
Psych disorders: 20 Questions
Treatment: 10 questions
Social Psych: 10 questions
Chapter 13: Social Psychology
Social influence: social facilitation, conformity, and obedience
Social Cognition: Attributions (Why?)
What is Social Psychology?
The scientific study of
1) how we think about (Attributions, why?)
2) Influence
3) Relate to one another
Are We Influenced by Other People?
Norman Triplett (1897)
Why do bicycle racers have better times when they compete head-to-head than when they compete “against the clock?”
To answer his question, Triplett studied children reeling fishing line alone or against a partner
Triplett found that most children reeled the line more quickly with a partner, but some children did so more slowly
Robert Zajonc (1965) proposed a resolution to the mixed findings of social facilitation research
Zajonc suggested that the presence of other people increases arousal, which enhances dominant responses
Therefore, social facilitation will cause well-learned (experienced) behaviors to be performed better and novel (newbie) behaviors to be performed worse.
Muzafer Sherif (1935)
Other people influence the autokinetic effect (method used)
People are influenced by others when they do not have a good reference point (ambiguous)
The moving red dot in a dark room, graph converging
Are We Influenced by Other People? … If the Answer is Obvious?
Solomon Asch (1955)
Hypothesized that people would not be influenced when information is objective
Task: students match a line with a series of three other lines
DECEPTION
Does not tell you he is doing this study to peer pressure and conformity
Only one participant in a room of confederates (NPC)
NPC give the right answer the first couple of times and then start to give the wrong answer
How Often Were People Influenced to Make Errors?
People “misjudged” the length of the line 36.8% of the time (⅜)
As the number of confederates grew, the misjudgements became more frequent
Are We Influenced by Other People? … To Perform Harmful Behaviors?
Stanley Milgram (1963)
Obedience
Why did people follow orders during the Holocaust?
Would people follow the orders of an authority figure if doing so might result in another person’s death?
Deceptions
1) Tells participants the study is about about learning and memory
2) Tells you that you are going to be randomly assigned to be the teacher
The learner is a confederate
3) Confederate tells authority figure he has a heart condition
4) authority figure tells him shocks hurt but are not deadly even though the shock box says each level of shock
5) Confederate is not actually getting shocked
Results
⅔ went to the very end of the shock level after the man stopped responding just because an authority figure said to do so
Teachers were really shook up after the study which caused them to experience a lot of stress
Replication of study remade at Santa Clara in 2008 showing the same results regardless of gender
What is an Attribution?
How do ordinary people explain another person’s behavior?
Is the behavior due to the situation or the person’s disposition?
External explanation: looks for external things that might be driving that outcome, situation
If you fail a math test was it because you had a family emergency, were you sick, did a pet pass away.
sympathetic
Internal explanation: it is within that actor, disposition
If someone walks in late right now you might be like you are late all the time
No sympathy, assumes the worst or the best based on one action
How Do We Determine the Cause of Other People’s Behavior?
Harold Kelley (1967)
Attribution Theory: WHY?
To what do people attribute the cause of another person’s behavior?
Situation (external, factors people cannot control) or Disposition (internal, within the person)
Kelley suggested three sources of information used in making attributions:
Distinctiveness
Unique?
Outlier?
Consistency (over context and time)
Are you seeing this again and again?
If so it says something about what you are attributed to
Consensus
Agreement?
Is that other set of people you are talking too all on the same page?
Can everyone see the behavior linked to the attribution?
Example: why is your roommate being rude?
Distinctiveness: is the behavior (relatively) uniquely related to this person or object?
Is your roommate ruder than anyone else you’ve ever met?
YES
Consistency: Does this behavior recur over time and in different contexts?
Is your roommate pretty much always rude?
YES
Consensus: Do other people agree with the assessment of the person?
Do your neighbors agree that your roommate is a rude person?
YES
This whole scenario with three yes’s leads to a dispositional attribution
If there are three no’s this leads to a situational attribution
Do People Make Mistakes in Their Attributions?
Edward Jones and Victor Harris (1967) discovered what came to be known as the fundamental attribution error (FAE).
FAE: 1.) overestimate, 2.) dispositional, 3.) others
People tend to overestimate the dispositional explanations for other people’s behavior.
Ex: How smart are “quizmasters” versus “contestants” on game shows?
