Objective: The aim of the present study was to analyze the body sway response in specific phobia (SP) patients and healthy controls while viewing neutral, phobic, and disgusting images.
Methods: The participants' heart rate (HR) and skin conductance were also recorded during the procedure. Nineteen patients with arachnophobia and 19 healthy volunteers matched by age, gender, and years of education underwent a postural control test on a stabilometric platform.
Objective: We investigated the hypothesis that rimonabant, a cannabinoid antagonist/inverse agonist, would increase anxiety in healthy subjects during a simulation of the public speaking test.
Methods: Participants were randomly allocated to receive oral placebo or 90 mg rimonabant in a double-blind design. Subjective effects were measured by Visual Analogue Mood Scale.
Social anxiety (SA) has as its main feature the fear of social situations, being characterized as social phobia or social anxiety disorder when functional impairment emerges as a result of that fear. Although the recognition of the condition has increased in recent years, it is believed that many patients and physicians still take the symptoms of the disorder for personality traits with no need for treatment. There is evidence that people with SA display abnormal patterns of facial emotion processing that could account for the onset and maintenance of the disorder.

Therefore, we assessed the recognition of facial expressions by individuals with SAD, in an attempt to overcome the limitations of previous studies.
Methods: The sample was formed by 231 individuals (78 SAD patients and 153 healthy controls).
