PSY280 - Exam 1 Flashcards
Abnormal
Psychological dysregulation associated with distress or impairment in functioning that is not typical nor culturally expected/accepted. Behavior that is unusual along w/ Social deviance: -faulty perceptions of reality -significant personal distress -maladaptive/self-defeating behavior -dangerousness
Supernatural Tradition (Late 15th-17th century)
Deviant Behavior = Battle of “good vs. evil”
–demonic possession, witchcraft, sorcery, movement of moon/stars, lunacy.
Treatments inc: exorcism, torture, beatings, crude surgeries (trephination).
—Witches voluntarily work w/ devil (women, poor/unmarried/disobedient. Attempt at diagnosis: death either way.
Reform Movement (Late 18th-Early 19th)
1450-1550- horrible asylum conditions so Rise of Moral Therapy (Pinel/Pussin)
–Benjamin Rush (reforms in US), Dorothea Dix (mental hygiene movement).
Moral Therapy declines in 1880s: MI not curable - lifelong institutionalization and little/poor care
Early Medical Models
Hippocrates (~400bc) said Abnormal behavior as Physical Disease (first break from Demonology)
Fluids=humors: black bile is depression, yellow bile is quick-tempered, blood is cheerful/confident/optimistic, phlegm is lethargic.
Galen: Discovered arteries carry blood not air.
Galenic-Hippocratic Tradition: linked abnormality w/ brain chemical imbalances and foreshadowed modern views.
Impact of Biological Tradition
Mentall Illness ~ Physical Illness
1930s Biological treatment standard: insulin shock therapy, ECT, brain surgery
1950s medications increasingly available: anti-psychotics, major tranquilizers. many released from institutions.
Community Mental Health Movement
Communities can better meet its members needs: Congress est. nationwide Community Mental Health Centers (CMHCs) and anti-psychotic drugs widely available. Deinstitutionalization
Psychoanalytic Theory
From Moral Therapy & Charcot’s use of hypnosis to treat hysteria– Freud’s theory that intrapsychic forces in subconscious are MI
1st major theory of abnormal behavior
Conflict within - blocked emotions - physical manifestations
Treatment: discharge of blocked emotions (catharsis), restored physical functioning. - Modern Psychodynamic Theory
Sociocultural Perspective
Society fails the person so abnormal behavior occurs. Mental illness is a myth.
Labels harm/stigmatize/reify abnormality (Thomas Szasz) - pathologies those that threaten the establishment, permits denial of societal injustices.
Biopsychosocial Perspective
Interactionist model: Abnormal Behavior too complicated for simple models; must consider biological/psychological/sociocultural factors.
Current trend in the field - behavioral genetics.
Multidimensional Models of Abnormal Behavior
Biological, Environmental/Psychological, Developmental
Etiology: Cause/source
Multidimensional: system of multiple influences
Biological Influences: Genetic
GENES: (DNA) molecules on chromosomes that contribute to physical/behavioral similarities among biological relatives. Polygenesis: influenced by many genes (genius).
Behavioral Genetics: Discipline concerned w/ genetic and environmental influences on behavior (examine patterns of familial relationships for heritability estimates)
Heritability: proportion of variability in trait/disorder due to genes.
30-70% heritability, Schizophrenia, anorexia Nervosa, Autism are among most heritable of psych disorders (>60%)
IQ 62%, Personality (50%)
Concordance
2 ppl have/not a disorder.
Discordance
One person has and other does not
Diathesis-Stress Model
Diathesis: predisposition/vulneraility \+ Stress: environmental Stressors = Development of disorder (stronger diathesis, the less stress necessary to produce disorder).
Reciprocal gene-environment model
When genes increase likelihood that individual will encounter environmental rigger: children w/ genes for musical talent drawn to musical environments.
Neurobiological
Genes code for proteins: genes for psychopathology likely code for proteins operating in brain.
Frontal lobe is most important for psychopathology.
Neurotransmitters important in mental illness
Dopamine
GABA
Norepinephrine
Serotonin
Serotonin:
Influences processing of info/aggressiveness/eating/sexual behavior.
-At low levels: increased impulsivity/overreactivity/decreased inhibition
Disorders affected: depression/anxiety/eating disorders
–Prozac: selective serotonin reuptake inhibitor (SSRI)
GABA
Inhibits emotions and behavior:
- reduces anxiety
- regulated by Benzodiazepines
Dopamine
“Switch” that inhibits/facilitates emotions/behavior
- balances serotonin
- schizophrenia/aggression may = excess dope
- ADHD/Parkinsons = low dopamine
Neurotransmitters in Different parts of the brain
- May affect functioning of other NTs
- may affect membrane of receptor cell and activate/inhibit that cell’s functioning
- -Excess/deficit itself can occur for many reasons (presynaptic neuron releases or reuptakes too much or too little, receptor site more/less sensitive to NT, may be reacting to excess/deficit of another NT).
Meds and Neurotransmitters
- Agonist drugs activate receptor neuron to produce desired response (increases action of NT)
- Antagonist drugs block receptor neuron from activation
- Reuptake inhibitors (SSRIs) increase action of NT by decreasing pre-synaptic neuron’s ability to reabsorb NT in order to reuse/destroy it.
Family Factors
- Shared: environmental factors shared by siblings growing up in same family
- Non-shared: influences not shared by siblings in same family (different treatment from siblings/parents)
Sociocultural Influences
Gender, ethnicity, mental health (SES and RACE are confounded).
Influences of population projections on mental health:
-treatment needs
