medical model

the concept that psychological disorders are caused by physical things and diagnosed, treated, and often cured through treatment in a hospital

biopsychosocial approach to psychological disorders

the concept that psychological disorders are caused by a variation of by biological (evolution, genes, brain structure & chemistry), psychological (stress, trauma, mood), and social-cultural (roles, expectations, definition of what’s normal versus abnormal) factors

DSM-5

the American Psychiatric Association’s Diagnostic and Statistical Manual of mental disorders, 5th edition; widely used to classify psychological disorders (critics say that this labels normal behaviors as disordered behavior, causing over-medication and more)

anxiety disorders

an anxiety disorder that causes a fear of situations or locations where panic has ensued before, leading to avoiding them

obsessive-compulsive disorder (OCD)

an anxiety disorder that cause unwanted repetitive thoughts and/or actions; caused by deficit of serotonin and too much epinephrine

post-traumatic stress disorder (PTSD)

an anxiety disorder that is caused by a traumatic experience, leading to haunting flashbacks to the event (PTSD is not guaranteed after a traumatic event, factors such as how traumatic it was and the person’s genes + limbic system sensitivity affect if PTSD develops and how long it lasts)

post-traumatic growth

positive psychological effects of struggling with trauma (ex. becoming more strong mentally)

neurodevelopmental disorders

a category of disorders that typically emerge during the time we are developing (childhood and adolescence), are inherited through genes, and usually involve dysfunctions in personal, social, academic, and/or occupational areas

serious mental illnesses that affect how a person thinks, feels, and behaves; seem ‘disconnected’, symptoms include delusions, hallucinations, disorganized speech, disorganized behavior, disorganized thoughts, and reduced emotional expression

schizophrenia

a psychological disorder and form of psychosis characterized by delusions, hallucinations (usually hearing a voice that is insulting them or giving them orders), disorganized speech, disorganized thoughts (inability to focus on a single stimuli and differentiate between significant and irrelevant stimuli, such as being too focused on a brick wall’s grooves to listen to the person talking to you), and/or diminished or inappropriate emotional expression (ex. smiling when told bad news (inappropriate) or not reacting at all (diminished))

are people with schizophrenia able to easily maintain relationships?

no

when does schizophrenia show up?

during the transition into adulthood

is schizophrenia gradual, sudden, or either?

can be either

brain activity of schizophrenic people

low brain activity in the frontal lobes

what are hallucinations, what disorder are they symptoms of, and how do they affect brain activity?

false sensory experiences, schizophrenia, increase of activity in the thalamus

how does paranoia affect brain activity?

increased activity in the amygdala

how does prenatal environment influence whether or not someone gets schizophrenia?

having a low birth weight and oxygen deprivation during birth determines whether the related genes activate or not

psychosis

a psychological disorder in which a person loses contact with reality, experiencing irrational ideas and distorted perceptions

bipolar disorder

a mood disorders in which a person alternates between hopelessness + the lethargy of depression and the overexcited state of mania

biological approach to mood disorders

often run in the family, depression is the outcome of numerous genes interacting, a depressed state diminishes brain activity while a manic state causes more activity, there is too little norepinephrine when depressed and too much when manic

social-cognitive approach to mood disorders

depressed people focus on negative experiences while diminishing the positive ones, experience rumination (overthinking about problems and their causes), and believe themselves entirely when something goes wrong

• very little fear of everything

• antisocial behavior and childhood neglect/abuse

• hyper-active dopamine reward center drives impulsive behavior

somatic symptom disorder

a psychological disorder in which the symptoms take a somatic (bodily) form without an apparent physical cause

a disorder in which a person experiences very specific genuine physical symptoms for which no actual physiological reason can be found (ex. unexpected paralysis, blindness, inability to swallow, etc.)

illness anxiety disorder

a disorder in which a person interprets normal physical sensations as symptoms of a disease (ex. thinking a normal stomach cramp is food poisoning)

psychotherapy

treatment involving psychological techniques; consists of interactions between a trained therapist and the patient/client

biomedical therapy

prescribed medications/procedures that act directly on the patient’s physiology

eclectic approach

an approach to psychotherapy that uses various techniques from different forms for therapy based on the patient’s problem

insight therapies

variety of therapies that aim to improve psychological functioning by increasing the patient’s awareness of underlying motives and defenses (ex. psychoanalysis, psychodynamic, humanistic)

psychoanalysis

freud’s therapeutic technique; patient’s free associations, resistances, dreams, etc. reveal repressed feelings/motives

• conflict between id, ego, and superego causes distress and revealing that distress helps the patient

• focuses on how childhood formed the person the patient is today

• not commonly used in modern times due to its lack of evidence/objectivity

resistance

• in psychoanalysis, the deliberate blocking from consciousness of something that brings anxiety

• interpretation:

• in psychoanalysis, how the therapist sees things the client says or doesn't say and what they do or what they don’t do and how it reveals something about them

• transference

• in psychoanalysis, the patient’s transfer of emotions linked with other relationships to the therapist (ex. hate for a parent transfers to hate for your therapist)

psychodynamic therapy

therapy derived from psychoanalysis that views people as responding to unconscious forces and childhood experiences, seeks to enhance self-insight

• no mention of id, ego, and superego

• face-to-face, a couple times a week for a few weeks/months

• explores thoughts that are usually defended against/blocked out

• interpersonal psychotherapy

• a variation of psychodynamic therapy but less focused on past experiences and more focused on current emotions and relationships

humanistic therapy

aims to boost self-fulfillment through increased self awareness; promotes growth rather than “curing” the problem, responsibility of feelings/actions rather than uncovering their hidden motives, conscious thoughts are more important than unconscious ones, focus on the present + future rather than the past

• client-centered/person-centered therapy

• a humanistic therapy developed by Carl Rogers in which the therapist uses techniques such as active listening within a genuine environment to facilitate the patient’s growth

  • non-directive; therapist listens and refrains from guiding the patient anywhere specific

  • patient’s guard gradually goes down because they know that someone is actually listening

• active listening

• in client-centered therapy, where the therapist emphatically listens and only interrupts to restate, clarify, or echo/validate

• unconditional positive regard

• caring and nonjudgmental attitude that Carl Rogers believed helps patients develop self-awareness/acceptance

behavior therapy

therapy that applies learning principles to the elimination of unwanted behaviors

• counter-conditioning

• behavior therapy procedure that uses classical conditioning to evoke new responses to stimuli that are triggering unwanted behavior; including exposure therapy and aversive conditioning

• exposure therapies

• behavioral techniques, such as systematic desensitization and virtual reality exposure therapy, that treat anxieties by exposing people (in imagination or in real life) to the things they fear or avoid

• systematic desensitization

• a type of exposure therapy that associates a pleasant state with gradually increasing anxiety-triggering stimuli; commonly used to treat phobias

• virtual reality exposure therapy

• a type of exposure therapy that progressively exposes people to electronic simulations of their fear; used when actually acting it out is inaccessible

• aversive conditioning

• a type of counter-conditioning that associates an unpleasant state with an unwanted behavior (ex. painting bitter nail polish on your nails to stop yourself from biting them); less effective in the long run

token economy

an operant conditioning procedure in which people earn a token of some sort for exhibiting a desired behavior and can later exchange the tokens for treats/prizes

cognitive therapy

therapy that teaches people new, more adaptive ways of thinking; based on the assumption that thoughts intervene between events and our emotional reactions to them

• rational-emotive behavior therapy (REBT)

• a confrontational cognitive therapy developed by albert ellis that vigorously challenges people’s illogical, self-defeating attitudes

• cognitive-behavioral therapy

• a popular integrative therapy that combines cognitive therapy (changing self-defeating thinking) with behavior therapy (changing behavior)

  • ex. when a person with OCD feels an urge coming on, they take a walk instead

group therapy

therapy conducted with groups rather than individuals, permitting benefits of being in a group (feeling less alone, feeling seen)

• family therapy

• therapy that treats the family as a system; views an individual’s unwanted behavior as influenced by or directed at family members; aims to heal familial relationships by providing a means to communicate and resolve conflict

how is the effectiveness of psychotherapy tested and what is the result?

psychotherapy’s effectiveness can be tested in the most objective sense by comparing the results of people who have been treated with psychotherapy versus people who haven’t; research has found that it is generally helpful as it speeds up recovery

psychopharmacology

the study of the effect of drugs on the mind and behavior

anti-psychotic drugs

drugs used to treat schizophrenia and other forms of psychosis by causing less responsiveness to irrelevant stimuli; side effects include sluggishness, tremors, twitches

anti-anxiety drugs

drugs used to control anxiety and agitation by depressing central nervous system activity; can become an addiction and cause withdrawal effects

antidepressant drugs

drugs used to treat depression, anxiety disorders, OCD, and PTSD by acting as selective serotonin reuptake inhibitors (SSRIs) and agonists

• increase availability of certain neurotransmitters like norepinephrine and serotonin

• side effects include dry mouth and weight gain, which can be reduced by administration through a patch

• most useful for severe cases of depression

mood stabilizers

stabilize emotional extremes such as the ones present with bipolar disorder (ex. lithium)

electroconvulsive therapy (ECT)

a biomedical therapy for severely depressed patients in which a brief electric current is sent through the brain of an anesthetized patient; often used for people who are unresponsive to drugs, side effects include seizure and memory loss

transcranial magnetic stimulation

a form of ECT that includes the application of pulses of magnetic energy to the brain; used stimulate nerve cells that are suppressed due to depression and calm the parts that are overactive, no anesthesia needed and no serious side effects

psychosurgery

surgery that removes or destroys brain tissue in an effort to change behavior

• mostly replaced by medical treatments nowadays

• lobotomy

• a psychosurgical procedure that was once used to calm uncontrollably emotional or violent patients by cutting the nerves that connect the frontal lobes to the emotion-controlling centers of the inner brain
