Social Phobia as a MisCommunication Disorder

1. Face perception represents a cognitive ability that involves:

A. Recognition of identity

B. Processing of facial expressions

C. Eye gaze

D. All of the above


2. Differences in task-related activations between social phobic patients and healthy controls are limited to brain areas related to the processing of emotional expressions and personality traits.

A. True

B. False


3. In patients with a variety of psychiatric disorders, functional correlation analysis has shown a mis-communication among brain areas for:

A. Face perception

B. Personality traits

C. Emotional expression

D. All of the above


4. A significantly reduced functional connectivity between the amygdala and perigenual anterior cingulate cortex has been shown in patients with _____ as compared to healthy controls during processing of face stimuli.

A. Anxiety

B. Bipolar disorder

C. Schizophrenia

D. Depression


5. Overall, social phobic patients and healthy controls showed different patters of functional connectivity across brain regions with the _____ for face perception.

A. Core system

B. Extended system

C. Both (A) and (B)

D. None of the above


6. Since accuracy and reaction times were similar between the social phobic patients and the healthy controls, the differences in brain functional connectivity cannot be due to differences in behavioral performance.

A. True

B. False


7. Both the left fusiform gyrus and the left superior temporal sulcus showed a stronger negative correlation with the left precuneus in healthy controls as compared to social phobic patients.

A. True

B. False


8. Since the precuneus plays a role in self-focus perception, its altered connectivity may be related to the attentive bias described in anxiety disorders, which leads anxious subjects to attend to the physiological signs of anxiety and to experience negative self-evaluation.

A. True

B. False


9. Recent studies have shown a stronger amygdala response in social phobic patients during a face recognition task with:

A. Emotional facial expressions

B. Neutral faces

C. Both (A) and (B)

D. None of the above


10. The left amygdala was positively correlated with the inferior frontal / insular cortical regions in:

A. Patients with Social Phobia

B. Healthy controls

C. Both (A) and (B)

D. None of the above
