what is a syndrome
a collection of symptoms that occur together

symptoms: subjectively reported behaviours, thoughts, and emotions
what is the diathesis-stress model?
a person may be predisposed to a psychological disorder that remains unexpressed until triggered by stress
what does it mean that the DSM-5 is atheoretical/descriptive?
it means that is only a tool for describing and diagnosing, not for explaining why a disorder occurred
what are the main criticisms of the DSM-5?
- categorical (treats most disorders as have or have not, when variations in severity exist)
- comorbidity (having 2 or more disorders in one person reduces diagnostic validity)
define anxiety
a state of apprehension and tension in which a person anticipates upcoming danger, catastrophe, or misfortune
how is anxiety differentiated from fear?
anxiety is anticipatory and does not always have a specific target
what are anxiety disorders?
disorders in which excessive, irrational, automatic, and impairing anxiety is the primary manifesting symptom
what are predictors of having an anxiety disorder?
anxiety disorders have strong family history and are correlated with high neuroticism
what are phobic disorders?
marked, persistent, and excessive fear and/or anxiety in presence or anticipation of specific objects, activities, and/or situations (i.e. phobias)
what are some neurobiological factors of phobias?
abnormalities in serotonin and dopamine; high levels of activity in amygdala
what is fear conditioning?
the theory that phobias are caused by associating a particular stimulus with a negative event through trauma
what is the little albert experiment?
a 6-mo infant who was not afraid of white rats was conditioned by pairing a loud noise every time he touched the rat; eventually his fear generalized to other white, furry things (i.e. rabbits, Santa Claus)
what is preparedness theory?
the theory that we are evolutionarily programmed to learn certain things even with very minimal experience
what is the Garcia effect?
when a rat is mildly poisoned once after drinking sugar water, they will never again drink sugar water, even if they were actually poisoned by something else
what is panic disorder?
a disorder characterized by the sudden occurrence of multiple psychological and physiological symptoms that contribute to a feeling of stark terror
what were the sodium lactate experiments and results?
compared the responses of people with and without panic disorder to sodium lactate, a chemical causing rapid/shallow breathing and heart palpitations
- those WITH panic disorder were acutely sensitive to the chemical, 60-90% experienced an attack
- those WITHOUT panic disorder rarely experienced an attack
what is agoraphobia?
a specific phobia associated with fear of public places, often co-morbid with panic disorder (most people are not actually scared of public places themselves, but rather what might happen there)
what is social anxiety disorder?
excessive anxiety around being judged by others, often to the point that the person avoids all social situations; the most commonly diagnosed anxiety disorder (note: this does not necessarily mean that it is the most prevalent, perhaps only the most impairing)
what is social anxiety disorder correlated with?
moderate correlations with temperament and neuroticism
what is GAD?
an anxiety disorder characterized by chronic and excessive worry accompanied by three or more of the following: fatigue, concentration problems, irritability, muscle tension, and sleep disturbances for more than 6 months
what is a possible cause of GAD?
seems to be in part related to the brain’s ability to inhibit information; patients with GAD show significantly higher levels of general brain activity
