Description
Chapter 14 – Psychological Disorder How to define “Abnormality”  Medical Model (Abnormality as a disease) o Mental illness being treated as a disease rather then a crime  Deviance o If it is deviant from the norm, it is “abnormal” o Examples  Drapetomania  When a slave exhibited the urge to escape from slavery  Homosexuality  Was considered deviant until 1973  Maladaptive Behaviour o Classify behaviours as maladaptive for individual or society as abnormal o Smoking is maladaptive for the individual and the society, should we be classifying you as abnormal?  Personal Distress o If we feel that we need help DSM ( Diagnostic and Statistical Manual)  Axis 1 – primary problems o Symptoms: mood, self esteem  Axis 2 – personality disorder o Eating disorder  Axis 3 – Medical conditions o Hypertension, diabetes  Axis 4 – External Stressor o No social network  Axis 5 – Functioning o Going from good to hurting oneself Criticisms  Rise in disorders since its first publication o Are we over diagnosing? o Powers of labels Anxiety Disorders  Anxiety that has no external causes Is not tied to a specific event for a specific threat o Generalized Anxiety Disorder  worry, putting the body into fight and flight mood by being constantly worrying, physical symptoms (Muscle tension, heart palpitations, sweating), worry that lasts up to six months o Obsessive-Complusive disorder  repetitive ritualized behaviour, checkers, symmetry, cleanliness, hoarders  External Causes  Triggered by some past event, an object/situation o Post traumatic stress  TRAUMA, vulnerability increases with intensity of event “aftermath”  requires a traumatic event to trigger it  Symptoms: nightmares, flashbacks, isolation from others, depression, anxiety, anger, increased arousal o Phobias  irrational fear of object, situation  Fear and physical symptoms o Panic disorder and Agoraphobia  Panic Attacks  when you have reoccurring panic attacks you have stress and interpret as it “doom” causing panic, “oh my god I am going to die”.  People will begin to isolate themselves from events that they believe will bring about a panic attack.

If you have 2 identical people, it is likely that they are going to experience the same environment  Learning o Associations between non-fear and fear.
