What Is Normal/Abnormal? • Unusualness of behavior/Deviation from average • Cultural relativism/Deviation from ideal • Subjective Discomfort • Inability to function/Maladaptiveness
Gender Role Expectations • How are men expected to act? What types of behaviors are discouraged? • How are women encouraged to act? What types of behaviors are discouraged?
Maladaptiveness • Does the behavior prevent normal daily functioning? • Does the person suffer distress? • Is there emotional or physical harm?

Contemporary Theories, cont. Vulnerability Stress Disorder
Structural Theories Abnormalities in the structure of the brain cause mental disorders Imbalancesin the levels of neurotransmitters or hormones, or poor functioning of receptors cause mental disorders Biochemical Theories Disordered genes lead to mental disorders Genetic Theories Biological Theories of Mental Disorders
Structural Causes of Dysfunction • Can occur in three areas of the brain: • Cerebrum • Central core • Limbic system • Can result from injury or disease
Behavior Genetics Questions • To what extent are behaviors or behavioral tendencies inherited? • What are the processes by which genes affect behavior?
Family History Studies • Identify people who clearly have the disorder in question – probands. • Researchers are most interested in first-degree relatives. • Problems?
Psychological Theories of Mental Disorders Psychodynamic Theories Unconscious conflicts between primitive desires and constraints of mental illness Symptoms of mental disorders due to reinforcements and punishments for specific behaviors and feelings Behavioral Theories People’s ways of interpreting situations, their assumptions about the world and self-concepts can cause negative feelings / behaviors Cognitive Theories Humanist and ExistentialTheories Conform to demands of others instead of pursuing own values and potentials
Psychodynamic Theories • Developed by Freud • Id • pleasure principle • Ego • reality principle • Superego • conscience & ego ideal
Newer Psychodynamic Theories: Object Relations • Stages • Undifferentiated • Symbiosis • Separation/Individuation • Integration
Behavioral Theories of Abnormality • Classical Conditioning • Pavlov • John B. Watson • Operant Conditioning • E.L. Thorndike (Law of Effect) • B.F. Skinner • Modeling & Observational Learning • Albert Bandura
Cognitive Theories of Abnormality • Types of cognition • Causal attributions • Control beliefs • Dysfunctional assumptions
Some Common Dysfunctional Assumptions Once something affects my life, it will affect it forever. I should be loved by everyone for everything I do. It is better to avoid problems than to face them. I must have perfect self control. I should be terribly upset by certain situations.
Humanistic & Existential Theories • Suggest that all humans strive to fulfill their potential for good and to self-actualize. • The inability to fulfill one’s potential arises from the pressures of society to conform to others’ expectations and values, and from existential anxiety.
Sociocultural Approaches Mental disorders result of long-standing patterns of negative relationships that have roots in early caregivers Interpersonal Theories Family Systems Theories Families create and maintain mental disorders in individual family members to maintain homeostasis. Social Structural Theories Societies create mental disorders in individuals by putting them under unbearable stress and by sanctioning abnormal behavior
Sociocultural Approaches: Interpersonal Theory • Alfred Adler • Erik Erikson • 8 Stages of Man • Harry Stack Sullivan • Prototypes – “good me”, “bad me”, “not me” • John Bowlby • Attachment Theory
Sociocultural Approaches: Family Systems Theory • The family is a complex system that works to maintain the status quo, or homeostasis. • Roots of disorder are within the family, not the individual. • Family systems theories may be more applicable to treatment of children since they are more enmeshed in the family than other members of the family.
Sociocultural Approaches: Social Structures Theory • Society increases stress on individuals, leading to disorders. • Some people live in more chronically stressful circumstances than others, and these people appear to be at greater risk (Gabrino, 1995; NAMHC, 1996). • Society influences the types of psychopathy by having rules about what types of abnormal behavior are acceptable and in what circumstances.
