  1. Causes of Abnormal Behavior Chapter 2

  2. Paradigms • (def)-a set of shared assumptions that include a theory and how data should be collected. • Four Basic Paradigms: • Biological • Psychodynamic • Cognitive-Behavioral • Humanistic

  3. Biological Definition: abnormal behavior is caused by biological abnormalities Cause of Abnormality: Genes, neurochemistry, head injury. Treatment:Medication or other physical treatments (ECT). Focus: Functions of the body and brain structures.

  4. Psychodynamic Paradigm Definition: abnormal behavior stems from unconscious conflicts from early childhood experiences. • Id – unconscious psychic energy strives to satisfy basic drives to survive, reproduce, and aggress  Pleasure principle • Ego – largely conscious, executive part of personality  Reality Principal • Superego- voice of conscious forces the ego to consider not only the real but, the ideal. Operates on conscious and unconscious level. Cause: Early Childhood Experiences Treatment: Psychoanalysis Focus: Unconscious Mind

  5. Cognitive Behavioral Definition: All behavior is the result of different forms of learning. -Classical Conditioning Operant Conditioning Social Learning Cause: Experiences (Nurture) Treatment: Cognitive Behavioral Therapy Focus: Observable Behavior

  6. Humanistic Definition: Emphasis on the Present and Future, and conscious rather than Unconscious. Cause: Frustrations in Society Type of Treatment: Non-directive Therapy Focus: Free Will

  7. Systems Theory Def- Integrates causes of abnormal behavior across biological, psychological and social factors. Diathesis-Stress Model and Multiple Risk Factors Equifinality Reciprocal Causality

  8. Biological Factors Neuron-basic building block of the nervous system. • Components that make up the neuron • Cell Body- • Dendrite- • Axon-

  9. Action Potential Neuron at rest— semi-permeable barrier between the fluids that are inside and outside the neuron. These fluids contain electrically charged particles called ions. Iinterior fluid is mostly negative and the exterior fluid is mostly positive. • Resting Potential-. • Polarization- • Depolarization- • Firing Of the Action-Potential • Release of Neurotransmitter- • Return to Resting State-

  10. Neurotransmitters and the Etiology of Psychopathology – • Biological research has found that there is a disruption in the functioning of certain neurotransmitters among some people with mental disorders. • Cannot currently measure neurotransmitter levels in a living brain. • Does not imply causality • Causes of disorders are multifactorial

  11. Major Brain Structures Central and Peripheral Nervous System: Central-Brain and Spinal Cord. Peripheral-is the sensory and motor neurons that connect the CNS to the rest of the body. Three Main Subdivisions: Hindbrain Midbrain Forebrain

  12. Limbic System Links the higher mental processes of the forebrain with the hindbrain and midbrain. Thalamus Hypothalamus

  13. Peripheral Nervous system • . Autonomic – • Sypmathetic-arousing-prepares the body for emergency • Parasympathetic- calming- slows everything down after the emergency • Somatic-

  14. Etiology of Autonomic nervous system and abnormal behavior: • Overarousal • Underarousal

  15. ENDOCRINE SYSTEM chemical communication system, that consists of glands that secrete hormones into the blood- stream.  hormones

  16. Behavioral Genetics Basic Principles of Genetics: • Genotype-actual genetic structure of the individual. • Phenotype is the expression of a given genotype. • Allele • Locus • Dominant/Recessive Inheritance

  17. Family Incidence Studies • Twin Studies-monozygotic vs. dizygotic twins. • Concordance rates- • Adoption Studies • Genetics and Etiology

  18. Psychological Factors • Species-Typical Characteristics • Attachment Theory • Dominance

  19. Psychological Factors • Temperament • Opennes to experience • Conscientiousness • Extraversion • Agreeable • Neuroticism • Emotion • Positive • Negative • Learning and Cognition

  20. Social Factors • Social Support • Gender Roles • Prejudice and Poverty • Societal Values

  21. Psychological Factors • Sense of Self • Development and Developmental Transitions:
