“…In line with previous findings showing only weak negative associations between P et CO 2 and symptom perception (23)(24), we found no significant coherence between P et CO 2 and the selfreported affective experience, or between P et CO 2 and the self-reported physiological symptoms. Therefore, and given the highly normal P et CO 2 values, it is unlikely that symptom perception was due to hyperventilation.…”

“…Gender, voluntary control of respiration, and ACC were additionally included because of their potential influence on the dependent variables 2 . When modeling P et CO 2 , we also included hormonal contraception as a potential confounder (23).…”

“…Empirical evidence for response coherence in emotion, specifically in anxiety, is mixed (22). The few studies that investigated the response coherence between P et CO 2 and the self-reported affective experience, and between P et CO 2 and the self-reported physiological symptoms, also reported mixed results (13,15,(23)(24). There is only little knowledge on response coherence in MPA (20)(21).…”

Objectives and Methods: Self-report studies have shown an association between music performance anxiety (MPA) and hyperventilation complaints. However, hyperventilation was never assessed physiologically in MPA. This study investigated (a) the self-reported affective experience, self-reported physiological symptoms, and cardio-respiratory variables including end-tidal pCO2 (PetCO2), which is an indicator for hyperventilation, in 67 university music students before a private and a public performance. The response coherence between these response domains was also investigated. Results: From the private to the public session, the intensity of all self-report variables increased (all ps<.001). As predicted, the higher the usual MPA level of the musician, the larger were these increases (all ps<.10). The main cardio-respiratory variables except PetCO2 also increased from the private to the public session (all ps<.05), but these increases were not modulated by the usual MPA level (all ps>.10). PetCO2 showed a unique response pattern as reflected by an interaction between usual MPA level and session (p<.01): it increased from the private to the public session for musicians with low MPA levels and decreased for musicians with high MPA levels. Self-reported physiological symptoms were related to the self-reported affective experience (all ps<.05) rather than to the physiological measures (all ps>.17).Conclusions: The present findings show for the first time how respiration is stimulated before a public performance in music students with different levels of MPA. The hypothesis of a hyperventilation tendency in high performance-anxious musicians is supported. The response coherence between physiological symptoms and physiological activation is weak.

“…30 to .50 has been found systematically between NA ratings and subjective symptom scores. These subjective complaints are rarely associated with NA-related differences in objective health problems [12,18,19], nor with differences in autonomic or respiratory responses [20,21]. In the respiratory domain, it has been observed that high-NA asthmatics report more symptoms, are more inclined to use medication, and appear to have a higher chance to become hospitalized, regardless of their pulmonary status [22,23].…”

“…Another one is negative affectivity, i.e., the general tendency to experience negative emotions and self-image, introversion, and dwelling on failures and shortcomings. Individuals with a high level of negative affectivity tend to report more frequent and more severe dyspnea [120][121][122][123]. Also, patients with non-organic dyspnea seem to be more anxious and to report dyspnea more often than patients with dyspnea that accompanies pathologic changes [124].…”
