Reliabilities of Air and Water Caloric Responses

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Considering the water stimuli, it is clear that the warm stimulus provoked a stronger magnitude response than the cool stimulus (geometric means of 35.2 and 20.6 degrees/sec for warm and cool, respectively). Similar trends were reported by others (Baloh & Honrubia, 1990;Barber & Stockwell, 1980;Coats, et al, 1976;Ford & Stockwell, 1978;Hamersma, 1957;Jacobson, et al, 1993;Proctor & Glackin, 1985;Sills, et al, 1977;Zangemeister & Bock, 1980). Jacobson et al (1993) reviewed some of the possibilities that explain this trend.…”

“…Similarly to our findings, there are reports of higher responses in the cold temperature than in the hot one using water 26 , 28 , 35 and air 26 . Notwithstanding, other studies have shown that the hot stimulus caused more intense responses than its cold counterpart in the caloric test with water 9 , 14 and with air 9 , 11 , or that similar results were obtained with both temperatures in the tests with air 14 , 17 , 19 , 23 and with water 17 , 19 , 23 .…”

Table 2 depicts the mean, standard deviation, minimum and maximum values of the slow component angular velocity of the post-caloric nystagmus in the tests with air at 50°C and 24°C and with water at 44°C and 30°C in the right and left ears, and the p-value of the comparative statistical analysis, considering the order at which the tests were performed.…”
