Bottom Line: Loudness of the tinnitus was associated with reduced interoceptive performance under stress.Our results indicate that interoceptive sensibility and accuracy do not play a significant role in tinnitus.However, tinnitus might be associated with a tendency to overestimate physical changes.

ABSTRACT
In order to better understand tinnitus and distress associated with tinnitus, psychological variables such as emotional and cognitive processing are a central element in theoretical models of this debilitating condition. Interoception, that is, the perception of internal processes, may be such a psychological factor relevant to tinnitus. Against this background, 20 participants suffering from chronic tinnitus and 20 matched healthy controls were tested with questionnaires, assessing interoceptive sensibility, and participated in two tasks, assessing interoceptive accuracy: the Schandry task, a heartbeat estimation assignment, and a skin conductance fluctuations perception task assessing the participants' ability to perceive phasic increases in sympathetic activation were used. To test stress reactivity, a construct tightly connected to tinnitus onset, we also included a stress induction. No differences between the groups were found for interoceptive accuracy and sensibility. However, the tinnitus group tended to overestimate the occurrence of phasic activation. Loudness of the tinnitus was associated with reduced interoceptive performance under stress. Our results indicate that interoceptive sensibility and accuracy do not play a significant role in tinnitus. However, tinnitus might be associated with a tendency to overestimate physical changes.

fig2: Procedure of the Schandry task.

Mentions: Three within-subject conditions existed for this task: a baseline condition with the classic Schandry task, a condition following a social stress induction, and a control condition following physical exercise on an ergometer (see Figure 2). Each condition consisted of five consecutive trials of different length (20, 25, 30, 35, and 40 s) which were presented in randomized order. After each trial, participants had 10 s to report their heartbeat count to the investigator. A 30-second pause followed each trial. The beginning and the end of each trial were marked by a tone (onset tone: 800 Hz, 300 ms; offset tone: 500 Hz, 300 ms).
