Abnormal Psychology Exam 1 Study Guide Chapters 1, 3, 4, 6 and 7 Ch 1 - Introduction to Abnormal Behavior: How is Abnormal Behavior Defined? 1. Elements of abnormality • Deviant o Deviancy: this can be good or bad § Example of good: Cam is deviant at football, Yo-Yo Ma is deviant at playing cello o Violation of societal standards: what is normal and abnormal is culturally relative § Most disorders exist cross-culturally (but prominent features may differ) • Distressing o Suffering: everyone experiences distress from time to time § Does the behavior cause distress for the person? o Social discomfort § Does the behavior impact others? Is it uncomfortable to interact with the person? • Debilitating o Maladaptiveness § Does the behavior lead to some type of impairment or interfere with one’s life? § E.g., substance abuse o Irrationality or unpredictability 2. DSM-5 definition of abnormal behavior (lecture notes) • Clinically significant syndrome • Distress or disability (impaired functioning) • Not culturally sanctioned • Considered to reflect behavioral, psychological or biological dysfunction • BUT… symptoms alone are not enough 3. Benefits of classification • Provides a nomenclature for structuring information • Facilitates communication • Facilitates research • Practical reasons 4. Disadvantages of classification • Stigmatization o Stereotyping: automatic beliefs concerning other people that are based on minimal (often trivial) information o Labeling: assigning a person to a particular diagnostic category à can perpetuate the problem of stigmas • Loss of information due to use of shorthand • Diagnostic categories are heterogeneous 5. Criticisms of the DSM-5 (also located in chapter 4 of the book) • Are disorders truly categorical? (i.e., can someone simply “have it or not”?) • Arbitrary cutoffs • Lack of theory about etiology • Lack of scientific support Ch 3 - Causal Factors and Viewpoints 1. Define etiology • Etiology: the study of causation, or origination, of psychological disorders • Main goal of etiological research? 2. Types of Causal Factors (e.g., necessary, sufficient, contributory, distal, proximal) • Necessary cause: something that HAS to happen in order for something else to occur o If Disorder Y occurs, then Cause X must have preceded it • Sufficient cause: condition that guarantees the occurrence of a disorder (it’s enough to get the job done). But, without more information, you can’t assume that it’s a requirement o If Cause X occurs, then Disorder Y will also occur • Contributory cause: increases the probability of a disorder developing, but is not necessary or sufficient o If X occurs, then the probability of Disorder Y occurring increases • Distal: causal factors that occur relatively early before the onset of the disorder (genetics to depression) • Proximal: causal factors that occur prior to the onset of a disorder (bullying to depression) 3. Diathesis-Stress Model • View of abnormal behavior as the result of stress operating on an individual who has a biological, psychosocial or sociocultural predisposition to developing a specific disorder (diathesis: vulnerability) 4. Bio-psychosocial Model • View of a disorder developing due to a complex interaction of biological, psychological and social/cultural factors Biological Perspectives: 1. Biological viewpoints of abnormal behavior • Disorders are diseases of the nervous and endocrine systems that are inherited or caused by some pathological process (disorders are the result of neurological abnormalities) 2. Types of biological causes • Neurotransmitter abnormalities: abnormalities in the communication between neurons • Hormonal abnormalities: endocrine system influences nervous system • Genetic vulnerabilities: chromosomal abnormalities and gene abnormalities • Temperament 3. Abnormalities in communication between neurons – 3 possible • Too much production • Dysfunctions in deactivation (too long/short in synapse) • Problems with receptors (too sensitive, not recognizing neurotransmitter) 4. Hormonal abnormalities • Sex hormones are also implicated o Testosterone, estrogen, progesterone o Influences of hormones on developing nervous system partially explain sex differences in behavior • Hypothalamic-Pituitary-Adrenal (HPA) Axis: stress response system; problems in this system related to depression and PTSD 5. Genotype vs. phenotype • Genotype: a person’s total genetic endowment • Phenotype: the observed structural and functional characteristics that result from an interaction of the genotype and the environment 6. Genetic abnormalities • Polygenic: caused by the action of many genes together in an additive or interactive fashion • Genotype-environment correlation: genotypic vulnerability that can shape a child’s environmental experiences o Passive effect, evocative effect, active effect • Genotype-environment interaction: differential sensitivity or susceptibility to their environments by people who have different genotypes o Phenotype 7. Twin studies • Concordance: percentage of twins sharing disorder or trait • Disorder entirely due to genetics, monozygotic twins should be 100% concordant, and dizygotic twins ~50% concordant • If a disorder is entirely due to environment, MZ twins and DZ twins should be about equally concordant • If genes and environment play a role, MZ twins will have higher concordance than DZ twins 8. Temperament* (know the definition) • Temperament: a child’s characteristic emotional and arousal response to various stimuli 9. Brain dysfunction & Neural Plasticity • Neural plasticity: flexibility of the brain in making changes in organization and function in response to pre- and postnatal experiences, stress, diet, disease, drugs, manturation, and so forth Behavioral Perspective: 1. Behavioral viewpoint on abnormal behavior, including • What influenced its emergence, origins? o Arose in the early 20 century in part as a reaction against the unscientific methods of psychoanalysis o Initially developed through lab research rather than clinical practice with disturbed patients • What is maladaptive behavior the result of (2 possibilities)? o A failure to learn necessary adaptive behaviors or competencies, such as how to establish satisfying personal relationships o The learning of ineffective or maladaptive responses • Behaviorism and treatment o Focus of therapy is on changing specific behaviors and emotional responses— eliminating undesirable reactions and learning desirable ones 2. Classical Conditioning (including all terminology) • Classical conditioning: a basic form of learning in which a neutral stimulus is paired repeatedly with an unconditioned stimulus (UCS) that naturally elicits an unconditioned response (UCR). After repeated pairings, the neutral stimulus becomes a conditioned stimulus (CS) that elicits a conditioned response (CR) • Extinction: gradual disappearance of a conditioned response when it is no longer reinforced • Spontaneous recovery: the return of a learned response at some time after extinction has occurred 3. Operant (instrumental) Conditioning • Operant conditioning: form of learning in which if a particular response is reinforced, it becomes more likely to be repeated on similar occasions • Reinforcement: the process of rewarding desired responses • Response-outcome expectancy: when an individual learns that a response will lead to a reward outcome 4. Generalization • Generalization: tendency of a response that has been conditioned to one stimulus to be elicited by other, similar stimuli 5. Discrimination • Discrimination: ability to interpret and respond differently to two or more similar stimuli 6. Observational Learning • Observational learning: learning through observation alone without directly experiencing an unconditioned stimulus (for classical conditioning) or a reinforcement (for operant conditioning) Cognitive-Behavioral Perspective: 1. Cognitive-behavioral viewpoint on Abnormal Behavior, including • What influenced its emergence, origins? o Albert Bandura placed considerable emphasis on the cognitive aspects of learning o Focuses on how thoughts and information processing can become distorted and lead to maladaptive emotions and behavior • Cognitive-behavioral perspective influence on treatment? o Therapy focuses on the ways that a person’s cognitions, emotions, and behaviors are connected and affect one another • Criticisms o Cognitions are not observable phenomena and, as such, cannot be relied on as solid empirical data 2. Schemas • Schema: an underlying representation of knowledge that guides the current processing of information and often leads to distortions in attention, memory, and comprehension • When does psychopathology occur? o Different forms of psychopathology are characterized by different maladaptive schemas that have developed as a function of adverse early learning experiences 3. What influences schemas? • Experiences, culture, etc. 4. Assimilation and Accommodation • Assimilation: working new experiences into our existing cognitive frameworks, even if the new information has to be reinterpreted or distorted to make it fit in • Accommodation: changing our existing frameworks to make it possible to incorporate new information that doesn’t fit 5. Attribution Theory, including attributional styles (for depressed vs. non-depressed people) • Attribution theory: focuses on whether different forms of psychopathology are associated with distinctive and dysfunctional attributional styles • Attributional style: characteristic way in which an individual tends to assign causes to bad events of good events o Depressed- tend to attribute bad events to internal, stable and global causes o Non-depressed- tend to make internal, stable and global attributions for positive rather than negative events Sociocultural Perspective: 1. How do sociocultural factors influence abnormal behavior • Concerned with the impact of culture and other features of the social environment on mental disorders 2. Sociocultural causal factors (Low Socioeconomic Status, High Unemployment, & Prejudice and Discrimination based on race/ethnicity, sex/gender identification, sexual orientation, Social change and uncertainty, Urban stressors) • Low socioeconomic status: the lower the socioeconomic class, the higher the incidence of mental and physical disorders • High unemployment: recent evidence suggests that it’s the financial difficulties often resulting from unemployment that lead to the elevated levels of distress and mental disorders • Prejudice/Discrimination • Sex/gender identification • Sexual orientation • Social change and uncertainty • Urban stressors Ch 4 - Clinical Assessment 1. Why do we need formal assessment procedures? • Establishing baselines for various psychological functions so that the effects of treatment can be measured 2. Why is it important to assess social and behavioral histories? • Academic history • Environment and social context • Family history 3. What do we mean by reliable and valid measures? • Reliability: degree to which the instrument produces the same result each time it is used • Validity: extent to which an instrument actually measures what it is supposed to measure 4. What is a culturally fair (or unfair) psychological assessment? • Culturally fair elements o Items are not reliant on cultural information that is exclusive to a particular group o Based more on “innate” ability (ability that’s inherent or biologically/genetically embedded in an individual) 5. Neuropsychological Assessments – what are they? • Assessment instruments designed to measure a person’s cognitive (e.g., memory, problem-solving), perceptual and motor performance 6. Psychological Assessments – what are they? • Standardized sets of procedures or tasks for obtaining samples of behavior 7. Types of Psychological Assessments • Intelligence tests (WISC-IV and WAIS-IV) • Projective personality tests • Objective personality tests 8. Assumptions of Projective measures • In trying to make sense out of vague, unstructured stimuli, individuals “project” their own problems, motives and wishes into the situation 9. Problems with Projective Measures • Unstructured nature- also a strength • Focus on the unique aspects of personality- also a strength o These two make interpretation subjective, unreliable and difficult to validate • Require a great deal of time to administer and advanced skill to interpret Research Methods in Abnormal Psychology 1. Epidemiology • Epidemiology: the study of the distribution of diseases, disorders or health-related behaviors in a given population 2. Prevalence (including different types of) • Prevalence: number of active cases in population at any given period of time o 1 year prevalence o Lifetime prevalence 3. Incidence • Incidence: number of new cases that occur over a given period of time (typically 1 year) 4. Correlation* • Correlation: the tendency of two variables to change together • With positive correlation, as one variable goes up, so does the other • With negative correlation, one variable goes up as the other goes down 5. Comorbidity • Comorbidity: occurrence of two or more identified disorders in the same psychologically disordered individual 6. Sources of information • I don’t know what she means by this, but I will find out and include it in Tuesday’s notes 7. Why is it difficult to study abnormal behavior? • I don’t know what she means by this, but I will find out and include it in Tuesday’s notes Ch 6 – Panic, Anxiety, Obsessions, and Their Disorders 1. Fear vs. Anxiety • Fear o Basic emotion (shared by all animals) o Involves activation of the “fight or flight” response of the autonomic nervous system o Cognitive/Subjective § “Oh shit” is pretty much all you can think about o Physiological § Heart rate increases § Fight or flight response o Behavioral § Anything possible to survive what’s happening • Anxiety o Complex blend of unpleasant emotions and cognitions o Is more oriented to the future and more diffuse than fear o Cognitive/Subjective § Is everything going to be ok? Etc. o Physiological § Sweat increase § Nausea § Butterflies o Behavioral- biggest difference between fear and anxiety § Might avoid things they wouldn’t normally avoid o Anxiety can be adaptive- problem occurs when it is excessive o Not in the moment, just thinking something might happen 2. What defines something as an anxiety disorder? • Out of proportion to dangers truly faced • Severe enough to cause distress and/or impairment • Fear response exists even when stimulus is not present 3. Specific Phobia • What is it (including subtypes) o Characterized by a strong and persistent fear triggered by the presence of a specific object or situation plus avoidance of that object or situation o Subtypes: animal, natural environment, blood/injection/injury, situational, other • Gender, age of onset o Gender ratio varies (typically more females have a blood-injection-injury phobia than men; most animal-type cases are women) o Age of onset varies (animal and blood-injection typically early childhood. Others, typically adolescence or early adulthood) • Psychological Causes (including evolutionary perspective) o Behaviorism/learning § Classical conditioning § Observational learning § Individual differences in life experience o Evolutionary preparedness- there are some things we can develop phobias to easier than others (animals- spiders, snakes) § If something can kill us, we are more likely to develop a phobia for it • Biological Causes o Genetic and temperamental variables • Treatment o Exposure therapy (behavioral technique) o Exposure to feared stimulus is not harmful o Sometimes flooding can be used o Medications (not very effective) 4. Social Anxiety Disorder • What is it (including subtype) o Characterized by disabling fears of one or more specific social situations o Performance only subtype- giving speeches, performing on stage, etc. • Gender, age of onset o 3:1 to 2:1 (female to male) o Onset: typically mid to late adolescence – early adulthood • Psychological Causes (including evolutionary perspectives) o Behavioral- direct and observational learning o Cognitive biases § Uncontrollable, unpredictable • Biological Causes o Genetic and temperamental factors • Treatment o Exposure therapy- cognitive restructuring (reframe thoughts) o Medication 5. Panic Disorder & Agoraphobia • What is a panic attack o A discrete period of intense fear in which 4 of the following symptoms develop abruptly and peak within 10 minutes § Palpitations of pounding heart § Sweating § Trembling or shaking § Shortness of breath § Feelings of choking § Chest pain or discomfort § Nausea or abdominal distress § Feeling dizzy, lightheaded, or faint § De-realization or depersonalization § Fear of losing control § Fear of dying § Dumbness of tingling sensations § Chills or hot flashes • What is Panic Disorder and Agoraphobia o Panic Disorder: recurrent panic attacks that “come out of the blue” AND fears of having additional panic attacks o Agoraphobia: fear of situations in which escape might be difficult if you have a panic attack (or other embarrassing symptoms) • Gender, age of onset o 2:1 (female to male) o Early adulthood • Biological Causal Factors o Genetic factors o Biochemical abnormalities • Psychological Causal factors o Cognitive theory (plus hypersensitivity) o Pill/placebo effect o Anxiety sensitivity o Perceived control o Safety behaviors (e.g., carrying around pills) o Cognitive biases that maintain (notice minor bodily sensations) • Treatment o Medications o Cognitive-Behavioral Therapy § Exposure therapy § Cognitive restructuring Generalized Anxiety Disorder • What is it o Characterized by excessive and unreasonable anxiety or worry about many different aspects of life • Gender, age of onset o 2:1 (female to male) o Age of onset varies • Psychological Causal Factors o Perceptions of uncontrollability and unpredictability o The role of worry (belief that worry is a good thing) o Worry reduces physiological symptoms § However, increases the sense of danger and anxiety o Cognitive biases for threat • Biological Causal Factors o Genetic factors o Neurotransmitter and neuro-hormonal abnormalities • Treatment o Medications o Cognitive-behavioral treatment Obsessive Compulsive Disorder • What is it (what are obsessions? what are compulsions?) o Characterized by the recurrence of unwanted and intrusive and obsessive thoughts or distressing images; often accompanied by compulsive behaviors to cope with such thoughts o Obsessions: recurrent and persistent thoughts, impulses or images that are intrusive and inappropriate and cause marked anxiety or distress o Compulsions: repetitive behaviors or mental acts that drive an individual to perform acts in response to an obsession and can be 15 minutes to hours long • Gender, age of onset o 1.4:1 (female to male) o Late adolescence/early adulthood • Psychological Causes o Learned behavior o Preparedness o Cognitive causal factors • Biological Causes o Genetic factors o Neurotransmitter abnormalities • Treatment o Behavioral and cognitive-behavioral § Exposure and response prevention o Medication Body Dysmorphic Disorder • What is it (including associated features) o Characterized by obsessions about some perceived or imagined flaw or flaws in one’s appearance to the point one firmly believes one is disfigured or ugly (like Michael Jackson) • Gender, age of onset o Men = women o Usually adolescence • Causal factors o • Treatment Ch 7 - Mood Disorders What are mood disorders? - Types of moods Major Depressive Disorder - What is it? -Emotional, physiological/behavioral, and cognitive symptoms -Recurrent vs. single episode MDD -Course of Major Depressive Disorder - gender, age of onset What is Persistent Depressive Disorder?
