  8. Generalized Anxiety and Panic People with generalized anxiety disorder (GAD) feel extremely nervous, jittery, and worried all the time People with panic disorder feel normal most of the time, but suddenly, with no warning feel overcome with intense fear, like they are going to die

  9. Phobias • These are basically panic attacks brought on by exposure to a specific stimulus • Irrational fears that disrupt behavior • Common phobias • People suffering from phobias live otherwise normal lives

  10. Obsessive Compulsive Disorder OCD is characterized by excessive, repetitive, unwanted thoughts (obsessions) and actions (compulsions) The compulsive behavior is usually a maladaptive way to control the obsessive thoughts/anxiety

  16. Major Depression Major depression is a disorder of mood where a person feels depressed for at least two weeks at a time Episodes can occur just once in a lifetime or can recur, some last for just 2 weeks, others years

  19. Why/How do Mood Disorders Happen? • Just like anxiety disorders the Biological perspective is very popular • Genetic predisposition – mood disorders do run in families • Physiological basis – there are significant brain activity changes (frontal lobe) in depressed people • Social-Cognitive perspective • Cycle of negative moods and negative thoughts goes both ways • Pessimistic thinking is related to depression – college student study
