WHAT IS ABNORMAL?

Abnormal Psychology • The area of psychological investigation concerned with understanding the nature of individual pathologies of mind, mood, & behavior

Abnormal Psychology • Determining if someone has a disorder is typically based on an evaluation of the individual’s behavioral functioning by people with some special/professional authority

Abnormal Psychology • What helps psychologists to determine a disorder is a classification scheme called • DSM-IV-TR: classifies, defines, & describes 200 mental disorders emphasizes the description of patterns/symptoms (*changed and updated by committees of psychologists often)

Abnormal Psychology • Criteria Used to label behavior as “abnormal”: 1. Distress or Disabilityexperiences personal distress or disabled functioning produces risk of psychological deterioration or loss of freedom (ie. agoraphobia)

Abnormal Psychology 2. Maladaptiveness- acts in ways that hinder goals, doesn’t contribute to personal well-being, interferes with goals of others (ie. drinking heavily can’t hold a job

Abnormal Psychology 3. Irrationalityacts/talks in ways that are irrational or incomprehensible to others (ie. responding to voices that others cannot hear)

Abnormal Psychology 4. Unpredictability- behaves unpredictably or erratically (ie. smashing a window for no reason)

Abnormal Psychology 5. Unconventionality and Statistical Rarity- individual behaves in ways that are statistically rare; does not necessarily lead to abnormality (ie. low intelligence- rare & undesirable; a genius- rare, but desirable)

Abnormal Psychology 6. Observer discomfort- a person creates discomfort in others by making them feel threatened, or distressed in some way (ie. woman walking in the middle of the street talking to herself)

Abnormal Psychology 7. Violation of Moral & Ideal Standardsindividual violates expectations of how one ought to behave with respect to societal norms

Abnormal Psychology • The more extreme & prevalent the indicators are, the more confident we can be that they point to an abnormal condition • None of these are a necessary condition shared by all cases of abnormality

Abnormal Psychology • No single criterion by itself is a sufficient condition that distinguishes all cases of abnormal behavior from normal variations in behavior • The distinction between normal & abnormal is a matter of degree to which a person’s actions resemble a set of agreed-upon criteria of abnormality

Problem of Objectivity • To declare/decide someone has a psychiatric disorder is a judgment about behavior • GOAL: to make these judgments objectively- w/o bias • Some disorder judgments are more easily made w/o bias (depression & schizophrenia)

Problem of Objectivity • Once an individual has obtained an “abnormal label” people are inclined to interpret later behavior to confirm that judgment

Problem of Objectivity • Ex- Rosenhan’s experiment- several people faked hallucinations to get placed into a psych hospital once there they acted in a sane manner kept there for 3 weeks, & not one was identified as sane finally released with help from spouses/colleagues

History of Mentally Ill 1. For most of history, humans feared the mentally ill & associated them with evil; they were in some cases imprisoned or killed

History of Mentally Ill 2. 1700 s- idea emerges those suffering from psychological problems are “sick” and suffering from illness rather than being possessed or immoral. - Reforms evolved in the way the ill were cared for/classified/diagnosed (Pinel & Kraepelin)

History of Psychopathology 2. Psychological- various approaches perceive personal experiences, trauma, conflicts, and environmental factors, as the root of disorders - 3 Psychological Models of Abnormality:

History of Mentally Ill 3. Late 1700 s-Early 1800 semergence of psychological reasons for mental illness, b/c people began to use techniques like hypnosis that seemed to cure people of “hysteria”

History of Mentally Ill 4. Modern versions combine aspects of both medical and psychological models of mental illness

Etiology of Psychopathology 1. Biological- psychological disturbances are directly attributable to biological factors (structural abnormalities in the brain, bio-chemical process, and genetic influences) - Ex. - neurotransmitters, brain injury, infection

Etiology of Psychopathology A. Psychodynamic- cause of psychopathology is located inside the person; symptoms have their roots in the unconscious conflict & thoughts - if the unconscious is conflicted & tension filled person will be plagued by anxiety - conflict comes from struggle between Id, Ego, Superego

Etiology of Psychopathology B. Behavioral- abnormal behaviors acquired thru learning & reinforcement - focus on current behavior & conditions or reinforcements that sustain the behavior; NOT internal psychological phenomena or early childhood - symptoms arise b/c person learned ineffective ways of behaving

Etiology of Psychopathology C. Cognitive- agree w/ behaviorists, but w/ a twist; what matters is the way people perceive/think about themselves & about their relations w/ people & the environment - suggests psych. problems are result of distortions in perceptions of reality of a situation, faulty reasoning, or poor problem solving

Etiology of Psychopathology D. Sociocultural- emphasizes role culture plays - particular cultural circumstances in which people live, may define an environment that helps bring about distinctive types or subtypes of psychopathology

Non-Psychotic & Psychotic Disorders

Anxiety Disorders

Anxiety Disorders • Causes: 1. Biological- phobias are evolutionary (shared across cultures); ability of certain drugs to relieve anxiety shows a possible biological cause; genetic basis(twin study) for predisposition of 4 to 5 disorders

Anxiety Disorders 2. Psychodynamic- symptoms of anxiety come from unconscious conflicts/fear; symptoms are trying to protect the individual from pain - panic attacks result of unconscious conflicts bursting into consciousness - Panic Attacks

Anxiety Disorders 3. Behavioral- focus on the way symptoms are reinforced/conditioned - phobias- classically conditioned fears previously neutral stimuli become a frightening experience - OCD compulsive behaviors tend to reduce anxious thoughts reinforcing the compulsive behavior

Anxiety Disorders 4. Cognition- person may overestimate nature/reality of threat or underestimate ability to cope w/ threat - people w/ anxiety may interpret their own distress as a sign of impending disaster vicious cycle

Mood Disorders

SWBAT • Examine a video of psych patients at Bellevue Hospital • Analyze and discuss the patients according to their symptoms

Video • After viewing the video of patients at Bellevue Hospital, write a ½ page reaction, which will be discussed at the beginning of tomorrow’s class

SWBAT • Discuss Bellevue video reactions • Identify multiple perspectives of the causes of mood disorders • Analyze the difference between depression and bipolar disorder

Mood Disorders • Major Depressive Disorder- feeling of sadness/despair; usually appears before age 40; loss of previous source of pleasure; lasts avg. of 5 mos • Bipolar Disorder- episodes of severe depression and manic episodes; onset age 20 -29

Mood Disorders • Causes: 1. Biological- levels of serotonin & norepinephrine depression; levels mania - evidence of genetic factors (twin studies) influencing mood - some evidence that depressed people have small hippocampus

Mood Disorders 2. Psychodynamic- hostile feelings & unconscious conflicts originated in childhood - depression is anger turned inward toward the self; anger tied to intense & dependent childhood relationship where needs were not met

Mood Disorders 3. Behavioral- an effect of the amount of positive reinforcement & punishment depression (not enough positive & too much punishment) - also a connection between lack of social skills & depression

Mood Disorders 4. Cognitive a) - negative view of self - negative view of ongoing experience - negative view of future can lead to paralysis of will; no motivation to pursue goals

Mood Disorders b) - explanatory style; depressed people can’t control future outcomes that are important to them - pessimistic view - learned helplessness expectancy that nothing they can do matters Manic Depressive/Bipolar Disorder

Mood Disorders • Gender Differences in Depression: - women- 2 x more affected, esp. in adolescence due to puberty - why? more thoughtful response style & tendency to focus obsessively on problems - men- actively distract themselves from feeling depressed by focusing on something else

Mood Disorders • Suicide: - most depressed people don’t commit suicide; 50 -80% of suicides are attempted by depressed people - women attempt suicide 3 x’s more than men are more successful b/c of methods used

Mood Disorders - since 1960, youth suicide ; white males are the highest - most youth suicides have given signs

Personality & Dissociative Disorders

SWBAT • Explain the 5 types of personality disorders • Identify the causes of personality disorders • Analyze the Dissociateive Identity Disorder (DID) in “Inside Karen’s Crowded Mind”

Personality Disorders • Read, “Inside Karen’s Crowded Mind” and be prepared to discuss

Personality Disorders • Chronic, inflexible, maladaptive pattern of perceiving, thinking, or behaving • Personality traits are excessive in degree & rigid • Usually recognized by adolescence or early adulthood • Difficult to diagnose b/c of overlap between disorders

Personality Disorders • 5 Examples of Personality Disorders: 1. Paranoiddistrust/suspicious; suspect others are trying to harm them; often jealous but unable to accept criticism themselves

Personality Disorders 2. Histrionic- excessive emotionally & attention seeking; flamboyant, dramatic, seductive, manipulative; 2 x 3 x greater in women

Personality Disorders 3. Narcissistic- grandiose sense of self importance, need for admiration; problems in interpersonal relationships; tend to exploit others; have difficulty recognizing & experiencing how others feel

Personality Disorders 4. Antisocial- pattern of irresponsible, unlawful behavior (starts early) that violates social norms; don’t experience shame/remorse; disrupting class, getting into fights, running away from home; involved in crime (but not always)

Personality Disorders - indifference to the rights of others - impulsive, manipulative, aggressive - more apparent in males (3 -6 x) - lack of conscience by age 15 - aka: sociopath/psychopath

Personality Disorders 5. Borderline- 126 criteria, very complicated to diagnose & treat; out of control emotions; “clingy”, hypersensitive to abandonment; history of hurting self; mood instability; unstable personal relationships; more in women

Personality Disorders • CAUSES: - genetic component, 67% of identical twins share the same disorder - research also points to environmental circumstances: a) dysfunctional/physically abusive/neglectful families b) neurological damage prenatally

Dissociative Disorders • Disturbance in the integration of identity, memory, or consciousness • Dissociate/disown part of themselves • Dissociative amnesiaselective memory loss due to psychological reasons (major trauma)

Dissociative Disorders • DID/Multiple Personality Disorder: - 2+ distinct personalities exist w/in same individual - one personality is dominant - personalities often contrast w/ original self

Dissociative Disorders - developed b/c they tried to escape from their life many have history of on-going sexual & physical abuse - very controversial some believe it doesn’t exist, patients make it up & therapists coach/help them

Schizophrenia

Schizophrenia • Means split mind • Most serious type of disorder • Personality disintegrates thoughts & perceptions are distorted; emotions are dulled/flat • Thinking becomes illogical & disorganized

Schizophrenia • Hallucinations occur • Delusions & false beliefs • Incoherent language word salad • Sometimes neglect personal hygiene • Difference between mood disorders & schizophrenia = disturbed thinking

Schizophrenia • 2 Phases: - Positive symptoms (aka acute/active)symptoms very apparent (hallucinations, delusions, bizarre behavior, wild ideas) - Negative symptoms- flattened emotions, withdrawal, apathy, impaired attention

Schizophrenia • 4 Types of Schizophrenia: 1. Disorganized- incoherent patterns of thinking & language, bizarre behavior, emotions are flat or inappropriate to the situation; delusions, aimless, babbling & giggling

Schizophrenia 2. Catatonic- (not very common) disruption of motor activity, seem “frozen”, or motionless; or at other times excessive motor activity

Schizophrenia 3. Paranoid- often comes later in life, hallucinations; - delusions focus around: a) being persecuted b) delusions of grandeur (God, millionaire) c) jealousy- mate is unfaithful

Schizophrenia 4. Undifferentiated- (fairly common) mixture of symptoms, disorganized thinking 5. Residual- suffered from schizophrenia in the past, but it’s now dormant or in remission

Schizophrenia • CAUSES: - seem to have high levels of dopamine (Dopamine Hypothesis) - tends to run in families: genetic factors put people at risk, but environmental factors also must present themselves diathesisstress hypothesis

Schizophrenia - family interaction can be an environmental stressor - research shows that reducing criticism, hostility, and intrusiveness can help reduce reoccurrence of symptoms - often family behavior may not stop disorder, but can help manage it

Schizophrenia - Brain functions/structure might be different scans during hallucinations show increased activity in amygdala & lower activity in the frontal lobe

Schizophrenia - Neuro-developmental hypothesisprenatal exposure & delivery complication increase vulnerability low birth weight & oxygen deprivation - Maternal virus during pregnancy (esp. the flu) can increase probability

Schizophrenia • Most believe it’s the high level of dopamine or genetic

Schizophrenia • TREATMENT: - medication works to either block dopamine receptors OR prevent the release of dopamine - risks/side effects- tremors, seizures, slow mental functioning, drowsiness

Schizophrenia - Generally appears in adolescence or early adulthood - Patient falls into 3 Types: 1. treated successfully recover 2. partial recovery, but w/ frequent relapse 3. endure chronic illness & generally permanently hospitalized
