Q

What is the controversy surrounding personality disorder classification?

Dimensional Model (Alternative Model - AMPD): Disorders exist on a continuum of traits.

52
What brain abnormalities are linked to BPD?
Frontal lobe dysfunction (impulsivity), low glucose metabolism in the frontal lobes, and increased amygdala activity.
53
What is Linehan’s diathesis-stress theory of BPD?
Emotional dysregulation + invalidating environment → BPD. ->It’s a cycle reinforced by family response patterns. EX. Emotional dysregulation in the child → child makes enormous demands on his or her family → Great demands on the family → Invalidation by parents ignoring the demands → Child suppressing emotions, only to have them build up to an explosion → Emotional outbursts by child to which parents attend → parents reinforce the very behaviors they find aversive → back to emotional dysregulation in the child

61
What cognitive deficits are associated with psychopathy in ASPD?
Deficits in executive function—problems with planning and inhibiting irrelevant information.

Paralimbic system (anterior cingulate cortex, orbitofrontal cortex, insular cortex). ->These areas influence impulse control, emotional regulation, evaluation of rewards/punishments, empathy.
63
What is the Under-arousal Hypothesis?
People with ASPD have chronically low arousal, leading to risk-taking behaviors to increase stimulation.
64
How does the Yerkes-Dodson Curve relate to ASPD?
Poor performance occurs at both low and high levels of arousal—ASPD individuals are typically under-aroused.
65

75
What’s a possible issue with research on parental rejection in AvPD?
Studies are retrospective and may be influenced by memory bias.
76
How is AvPD similar to Social Anxiety Disorder (SAD)?
Both may involve an overactive behavioral inhibition system—perceiving too many stimuli as threatening.
77
What are some treatments for Avoidant Personality Disorder?
- Social skills training, specifically within a support group - CBT: graduated exposure to feared situations - Systematic desensitization: relaxing in the presence of feared situations - Behavioral rehearsal: patients act out situations that cause anxiety - Benzodiazepines, SSRIs
