Each provides _________________________________ that help us explain and interpret observations 1. Helpful because they spell out basic assumptions and set guidelines for investigation 2. They influence what investigators observe, the questions they ask, the information they seek, and their interpretation of that information Models of Abnormality 0. Historically, clinical scientists of a given time and place agreed on a single model of abnormality – a model greatly influenced by ___________________ 1. Currently, there are several competing models of abnormality 1. Why? Each model focuses on one aspect of human functioning and no single model can explain all aspects of abnormality The Biological Model 2. Takes a medical perspective 3. Main focus is that psychological abnormality is an illness brought about by _________________________________ 2. Typically focused on the _______________ How Do Biological Theorists Explain Abnormal Behavior? 4. Brain anatomy 3. The brain is composed of ~100 billion nerve cells (called _________ ) and thousands of billions of support cells (called _________ ) 4. Within the brain, large groups of neurons form distinct areas called brain ___________ How Do Biological Theorists Explain Abnormal Behavior? 0. Brain anatomy and abnormal behavior 5. Clinical researchers have found connections between certain psychological disorders and problems in specific brain areas 3. Example: Huntington’s disease & basal ganglia (forebrain) 5. Brain chemistry 6. Information spreads throughout the brain in the form of _______________ that travel from one neuron to one or more other neurons 7. An impulse is received at a neuron’s ____________, travels down the ____________ , and is transmitted to other neurons through the nerve ____________ 6.. Brain chemistry 6 8. Neurons don’t touch; they are separated by a space (the ____________), across which a message moves 9. When an electrical impulse reaches a nerve ending, the nerve ending is stimulated to release a chemical called a ______________ (NT) 4. Some NTs tell receiving neurons to “fire”; other NTs tell receiving neurons to stop firing 7. Brain chemistry and abnormal behavior 10. Researchers have identified dozens of NTs 5. Examples: serotonin, dopamine, and GABA 11. Studies indicate that abnormal activity in certain NTs can lead to specific mental disorders 6. Examples: depression (serotonin and norepinephrine) and anxiety (GABA), schizophrenia (dopamine) 12. Brain chemistry and abnormal behavior 7. Additionally, researchers have learned that mental disorders are sometimes related to abnormal chemical activity in the endocrine system 8. Hormone release, triggered by a variety of factors, propels body organs into action. Abnormal secretions have been linked to psychological disorders 9. Example: cortisol release is related to anxiety and mood disorders 13. Sources of biological abnormalities – ____________ 10. Humans have 23 pairs of chromosomes, each with numerous genes that control the characteristics and traits a person inherits 11. Studies suggest that inheritance plays a part in mood disorders, schizophrenia, mental retardation, Alzheimer’s disease, and other mental disorders 0. Aren’t able (yet) to identify specific genes 1. Don’t know the extent to which genetic factors contribute to disorders 2. Seems no SINGLE gene is responsible for ____________________ Sources of biological abnormalities – ___________________________ 12. Genes that contribute to mental disorders are viewed as unfortunate occurrences: 3. May be mutations 4. May be inherited after a mutation in the family line 13. Evolutionary theorists argue that we can best understand abnormality by examining the millions of years of human evolution 5. Looking at a combination of adaptive behaviors of the past, genes, and the interaction between genes and current environmental events 6. Example: Fear 8. Sources of biological abnormalities – ____________________________ 14. Infection provides another possible source of abnormal brain structure or biochemical dysfunction 14. Example: schizophrenia and prenatal viral exposure 15. Interest in viral explanations of psychological disorders has been growing in the past 15. decade 15. Example: anxiety and mood disorders Biological Treatments 9. Biological practitioners attempt to pinpoint the physical _________ of dysfunction to determine the course of treatment 10. Three types of biological treatment: 16. _____________________________ 17. _____________________________ 18. _____________________________ Biological Treatments 11. Drug therapy: 19. 1950s = advent of psychotropic medications 16. Changed outlook for a number of mental disorders 20.

Treatments produce significant __________ ___________________ The Psychodynamic Model 29. Oldest and most famous psychological model 30. Based on belief that a person’s behavior (whether normal or abnormal) is determined largely by underlying _______________ psychological forces _________________________ 28. Abnormal symptoms are the result of conflict among these forces 31. Father of psychodynamic theory and psychoanalytic therapy: 29. __________________ (1856–1939) How Did Freud Explain Normal and Abnormal Functioning? Caused by three ______________ forces: 30. 31. 32. 33. Id – guided by the ______________ Principle Instinctual needs, drives, & impulses Sexual; fueled by libido (sexual energy) Ego – guided by the ______________ Principle Seeks gratification but guides us to know when we can & can’t express our wishes Ego defense mechanisms protect us from anxiety Caused by three UNCONSCIOUS forces: 14. 0. 32. 33. Superego – guided by the ____________ Principle 9. Conscience; unconsciously adopted from our parents 34. These three parts of the personality are often in conflict 34. A healthy personality is one in which compromise exists among the three forces 35. If the id, ego, and superego are in excessive conflict, the person’s behavior may show signs of dysfunction How Did Freud Explain Normal and Abnormal Functioning? 15. Developmental stages 35. Freud proposed that at each stage of development, new events and pressures require adjustment in the id, ego, and superego 36. If successful → personal growth 37. If unsuccessful → fixation at an early developmental stage, leading to psychological abnormality 10. Because parents are the key figures in early life, they are often seen as the cause of improper development 16. Developmental stages 0. 36. _____________ (0 to 18 months of age) 37. _____________ (18 months to 3 years of age) 37. 38. _____________ (3 to 5 years of age) 39. _____________ (5 to 12 years of age) 40. _____________ (12 years of age to adulthood)
How Do Other Psychodynamic Explanations Differ from Freud’s? 41.

Emphasize the role of the ego; consider it independent 39. __________________ 12. Emphasize the unified personality over any one component 40. __________________ 13. Emphasize the human need for interpersonal relationships Psychodynamic Therapies 17. Range from Freudian psychoanalysis to more modern therapies 18.

Father of classical conditioning: ______________ (1849–1936) 51. Classic study using dogs & meat powder 29. Classical conditioning 56. If, after conditioning, the CS is repeatedly presented alone, it will eventually stop eliciting the CR 52. This process is called ________________________________ 57. Explains many familiar behaviors (both normal and abnormal) Behavioral Therapies 30. Aim is to identify the behaviors that are causing problems and replace them with more appropriate ones 58. May use classical conditioning, operant conditioning, or modeling 31. Therapist is “__________” rather than healer 52. Humans and animals learn to behave in certain ways as a result of receiving rewards 59. Early life experiences important only in providing clues tocurrent learning 59. 32. Classical conditioning treatments may be used to change abnormal reactions to particular stimuli 60. Example: _______________________ for phobia 53. Stepbystep procedure 19.

Rules, including “Here and Now” and “I” language Existential Theories and Therapy 1. Psychological dysfunction is caused by selfdeception: people hide from life’s responsibilities and fail to recognize that it is up to them to give meaning to their lives 2. Therapy is focused on patient acceptance of personal responsibility and recognition of freedom of action 1. Goals more important than technique 2. Great emphasis placed on clienttherapist relationship Assessing the HumanisticExistential Model 74. Strengths: 76. Emphasizes the individual 77. Taps into domains missing from other theories 37. ___________________ 78. ___________________ 79. Emphasizes health 75. Weaknesses: 80. ________________ 38. Difficult to research 81.

How Do Sociocultural Theorists Explain Abnormal Functioning? 44. Focus on: 79. Family structure and communication 85. ________________________ = abnormal functioning within family leads to abnormal behavior (insane behavior becomes sane in an insane environment) 40. Examples: enmeshed, disengaged structures 45. Focus on: 80. ________________________________ 86. Set of values, attitudes, beliefs, history, and behaviors shared by a group of people and communicated from one generation to the next 87. “Multicultural” psychology is a growing field of study 46. Focus on: 81. Religion and spirituality 88. For most of the twentieth century, clinical scientists viewed religion as a negative factor in mental health, but this alienation now seems to be ending: 41. Researchers have begun to systematically study the influence of religion and spirituality on mental health 42. Many therapists now address spiritual issues when treating religious clients Sociocultural Treatments 82. May include traditional individual therapy 83. Broadened therapy to include: 89.
