ANXIETY Anticipation of future problems Prepares us to take action Involves more general or diffuse emotional reactions
  • Slide 4
  • At the same time, we can also worry too much, feel anxious too often or be afraid at inappropriate times. The questions is: how maladaptive are these behaviors and to what extent do they interfere in ones ability to function normally?
  • Slide 5
  • Most common type of abnormal behavior Share similarities with mood disorders: Both defined in terms of negative emotional responses (Case of Johanna, inter and/or intrapersonal?) Close relationship between symptoms of anxiety and depression (e.g., guilt, worry, anger). May share similar causal features: stress, cognitive factors, biological.
  • Slide 6
  • People with anxiety disorders share a preoccupation with, or persistent avoidance of, thoughts or situations that provoke fear or anxiety. The diagnosis of anxiety disorders depends on several types of symptoms.

  • Panic Attacks (continued) Misinterpretations of bodily sensations lies at the core of panic disorder Heart palpitations heart attacks Racing thoughtslose their mind
  • Slide 13
  • Slide 14
  • Panic Attacks (continued) Described in situations in which they occur: Cued: if expected, or if it occurs only in the presence of a particular stimulus Unexpected: panic attacks appears without warning or expectation, as if out of the blue.
  • Slide 15
  • OBSESSIONS Unwanted, anxiety- provoking thoughts/images out of the blue May seem silly or crazy, socially inappropriate or horrific COMPULSIONS Compulsions cannot be resisted without distress Reduce (neutralize) anxiety, but do not produce pleasure Irrational rituals
  • Slide 16
  • stress disorder
  • Slide 17
  • Recurrent, unexpected panic attacks At least one of the attacks must be followed by a period of 1 month or more with persistent concerns about having additional attacks. Divided into two subtypes: presence of absence of agoraphobia
  • Slide 18
  • Slide 19

  • Slide 22
  • Fears are focused on social situations where there is a possibility of being judged/observed/humiliated/embarrassed Two broad headings: Performance Anxiety Interpersonal interaction
  • Slide 23
  • A marked and persistent fear that is excessive or unreasonable, cued by the presence or anticipation of a specific object or situation. Exposure to phobic stimulus must be followed by an immediate fear response. Catchall category
  • Slide 24
  • 1) Animals 2) Natural Environmental 3) Blood/Injury/Injection 4) Situational
  • Slide 25
  • Chronic (>6 mos),debilitating, excessive anxiety and worry Trouble controlling the worries Worries lead to significant distress Pervasive: worries must be about different events or activities Includes three or more of the following: Restlessness Sleep disturbance Fatigue Irritability Muscle Tension Difficulty concentrating
  • Slide 26
  • Slide 27
  • Recognition that the obsessions or compulsions are excessive or unreasonable. Attempts to ignore, suppress, or neutralize the unwanted thoughts or impulses.
  • Slide 28
  • Slide 29
  • > 2-3 times Relapse rates: higher for OCD: no significant gender differences Specific phobia: are three times more likely Panic disorder, agoraphobia (without panic disorder): about twice as likely Social phobia: more common among
  • Slide 30
  • Evolutionary perspective focuses on significance of anxiety and fear. Fear/Anxiety may mobilize. Help the person survive in the face of both immediate danger and long-range threats
  • Slide 31
  • Adaptive and Maladaptive Fears Preparedness Model (preconditioning theory) Research results appear to support that conditioned responses to fear-relevant stimuli (e.g., spiders, snakes) are more resistant to extinction that those to fear-irrelevant stimuli (e.g., flowers).
  • Slide 32
  • Causal patterns are complex. Multicausal. Stressful life events, particularly involving danger and interpersonal conflict, can trigger the onset of certain kinds of anxiety disorders and depression.
  • Slide 33
  • Nature of the event: important factor Anxiety: danger Depression: severe loss (lack of hope)
  • Slide 34
  • Maternal prenatal stress (higher cortisol levels at birth) Multiple maternal partner changes Parental indifference (neglect) Physical abuse. more likely to develop anxiety disorders
  • Slide 35
  • Anxiety is an innate response to separation, or threat of separation. People with anxiety disorders more likely to have had attachment problems as children.
  • Slide 36
  • Specific fears might be learned through classical conditioning. http://www.mathxl.com/info/MediaPopup.aspx?origin=1&disciplineGroup=5&type=Watch&[email protected] babyal.flv%20&width=-1&height=-1&autoh=yes&centerwin=yes http://www.mathxl.com/info/MediaPopup.aspx?origin=1&disciplineGroup=5&type=Watch&[email protected] babyal.flv%20&width=-1&height=-1&autoh=yes&centerwin=yes Watson and Rayner (1920) Little Albert study Conditioned fears persist and modify personality throughout life Mary Cover Jones (1924) later used classical conditioning to remove fears in another boy

  • White ratno reaction (NS) Loud Noise Fear (UCS) (UCR) White Rat + Loud NoiseFear (NS) (UCS) (UCR) White ratFear (CS)(CR)
  • Slide 38
  • Perceptions, memory, and attention all influence reaction to events. Four aspects: Perception of controllability Catastrophic misinterpretation Attentional biases Thought suppression
  • Slide 39
  • Control events in their environments: less likely to show anxiety than people who believe they are helpless. Feelings of lack of control = onset of panic attacks Anxiety Control
  • Slide 40
  • Catastrophic Misinterpretation Panic attacks can be precipitated by internal stimuli, such as bodily sensations, thoughts, or images. Misinterpret bodily sensations = catastrophic event. Automatic, negative thoughts lead to behaviors that are expected to increase safety, when they are in fact counterproductive.
  • Slide 41
  • Attention to Threat and Biased Information Processing Unusually sensitive to cues that signal the existence of future threats. Recognition of danger triggers maladaptive, self-perpetuating cycles that quickly spin out of control.
  • Slide 42
  • Trying to rid ones mind of a distressing or unwanted thought can have the unintended effect of making the thought more intrusive (especially for OCD).
  • Slide 43
  • Thalamus Amygdala Flight or Fight (behavioral responses coordinated through the hypothalamus)
