  38. 38. 38 of 53 Biomedical Therapies Biomedical therapies: medical treatment for mental disorders; includes drug therapy and medical procedures treating the brain
  39. 39. 39 of 53 Pharmacotherapy: Use of drugs to alleviate emotional disturbance; three classes: Antianxiety (Minor Tranquilizers): Produce relaxation or reduce anxiety (Valium, Lithium, Zanax) Antidepressants: Elevate mood and combat depression (Elavil, Paxil, Prozac, Zoloft) Antipsychotics (Major Tranquilizers): Tranquilize and also reduce hallucinations and delusions in larger dosages (Thorazine, Clozaril) Pharmacotherapy
  40. 40. 40 of 53 Problems with Drug Therapy • There can be serious side-effects (tranquilizers can cause neurological disorders; Clozaril associated with a fatal blood disorder) • Drugs do not cure the disorder; they only ameliorate the symptoms. • Reliance on drugs increase belief in the “quick fix”; belief that any disorder can be cured with a pill. • Generally, psychotherapy is needed in addition to medication.
  41. 41. 41 of 53 Electroconvulsive Therapy (ECT): Electric shock is passed through the brain inducing a convulsion. • Based on belief that seizure alleviates depression by altering brain chemistry • Used in treatment of depression • Produces only temporary improvement • Causes permanent memory loss in many patients • Should only be used as a last resort Shock Therapy
  42. 42. 42 of 53 Psychosurgery: Any surgical alteration of the brain Prefrontal Lobotomy: Frontal lobes in brain are surgically cut from other brain areas • Supposed to calm people who did not respond to other forms of treatment • Was not very successful Deep Lesioning: Small target areas in the brain are destroyed by using an electrode Psychosurgery
  43. 43. 43 of 53 Psychotherapy: Any psychological technique used to facilitate positive changes in personality, behavior, or adjustment; Some types of psychotherapy: Psychoanalysis: therapy based on Freud’s theory Client-centered therapy: based on Humanism Behavioral and Cognitive therapies What is Psychotherapy?
  44. 44. 44 of 53 Main Goal of Psychoanalysis: To resolve internal conflicts that lead to emotional suffering Free Association: Saying whatever comes to mind, regardless of how embarrassing it is. By doing so without censorship and censure, unconscious material can emerge Dream Analysis: Dreams express forbidden desires and unconscious feelings • Latent Content: Hidden, symbolic meaning of dreams • Manifest Content: Obvious, visible meaning of dreams • Dream Symbols: Images in dreams that have personal or emotional meanings Psychoanalytic Techniques
  45. 45. 45 of 53 Analysis of Resistance: analysis of blockage in flow of ideas; topics the client resists thinking about or discussing. Resistances reveal particularly important unconscious conflicts Analysis of Transference: analysis of tendency to transfer feelings to a therapist that match those the patient has for important people in his or her past. The patient might act like the therapist is a rejecting father, loving mother, etc. Psychoanalytic Techniques, continued
  46. 46. 46 of 53 Client-Centered Therapy (Rogers): Nondirective and based on insights from conscious thoughts and feelings Effective therapist must have four basic conditions • Unconditional Positive Regard: Unshakable acceptance of another person, regardless of what they tell the therapist or how they feel • Empathy: Ability to feel what another person is feeling; capacity to take another person’s point of view • Authenticity: Ability of a therapist to be genuine and honest about his or her feelings • Reflection: Rephrasing or repeating thoughts and feelings of the clients; helps clients become aware of what they are saying Client-Centered (Humanistic) Therapies
  47. 47. 47 of 53 Existential Therapy: An insight therapy that focuses on problems of existence, such as meaning, choice, and responsibility; emphasizes making difficult choices in life Therapy focuses on death, freedom, isolation, and meaninglessness Free Will: Human ability to make choices. You can choose to be the person you want to be Confrontation: Clients are challenged to examine their values and choices Humanistic Therapies
  48. 48. 48 of 53 Behavior Therapy: Use of learning principles to make constructive changes in behavior Behavior Modification: Using any classical or operant conditioning principles to directly change human behavior • Deep insight is often not necessary • Focus on the present; cannot change the past, and no reason to alter that which has yet to occur • Can also use classical conditioning techniques Behavioral Therapies
  49. 49. 49 of 53 Aversion Therapy: Associate a strong aversion to an undesirable habit like smoking, overeating, drinking alcohol, or gambling Flooding: client is exposed to feared object or situation. Behavioral Therapies
  50. 50. 50 of 53 Systematic Desensitization: Guided reduction in fear, anxiety, or aversion; attained by approaching a feared stimulus gradually while maintaining relaxation • Best used to treat phobias: intense, unrealistic fears • Hierarchy: Rank-ordered series of steps, amounts, or degrees • Reciprocal Inhibition: One emotional state is used to block another (e.g., impossible to be anxious and relaxed at the same time) Behavioral Therapies
  51. 51. 51 of 53 Cognitive Therapy: Therapy that helps clients change thinking patterns that lead to problematic behaviors or emotions Selective Perception: Perceiving only certain stimuli in a larger group of possibilities Overgeneralization: Allowing upsetting events to affect unrelated situations All-or-Nothing Thinking: Seeing objects and events as absolutely right or wrong, good or bad, and so on Cognitive therapy is VERY effective in treating depression, shyness, and stress Cognitive Therapy
