Description of 360° videos
bored and distractive behaviors
CLAP
Since the VR scenarios will be selected individually for every patient, an overview of the 360° videos is presented in Table Each video starts with a short 1.5-minute waiting phase in a backstage waiting room, where the participant can accommodate to the VR and prepare for the performance situation. The subjective fear rating is assessed verbally using a subjective units of distress (SUD) scale (0-100) before and after the feared situation as well as during the waiting phase. Scenario A consists of a professional jury (one man, two women) sitting in the audience of a large concert hall. The participant is located on a large stage at a distance of 4–5 m from the jury. The participant is asked by the jury to introduce him-/herself and the two pieces selected for the audition and then start to perform. Scenario B takes place in the same concert hall and has the order of sequence as scenario A, but differs in that the participant is performing behind a folding screen/paravent (similar to real audition situations) and thus unable to see the jury or the audience, and is interrupted by the jury while playing. Hence, scenario B has a total duration of 6.5 min (incl. the waiting phase). In scenario C, participants have to perform in a constrained area, i.e. on a small stage in a small concert hall in front of a professional jury (one man, three women). Two jurors (women) are sitting at a table in front of the first row in close distance to the musician. Similar to the procedure of the audition in scenarios A and B, after personal and musical introduction, the participant start to perform. After 2.5 min of performance, the participant is interrupted by the jury and asked to leave the stage. During the performance, the jurors take notes, carefully observe the participant and initiate eye contact amongst each other. Scenario D shows a concert situation in front of an audience consisting of 21 middle-aged people. It takes place in the same small concert hall as scenario C. When the participant enters the stage, the audience starts to clap hands. After ending the applause, the audience attentively listens to the performance of the musician. The scenario ends with the audience clapping hands enthusiastically after the musician finished the performance. Scenario E takes place in a classroom in front of an audience consisting of 17 music students displaying bored and distractive behaviors like talking to their neighbors, moving and changing seating positions, checking their phones, coming late to class, or leaving early. The Scenario has a duration of 6.5 min (incl. waiting phase). Scenario F takes place in the same classroom with the same audience of music students. In contrast to scenario E, the students in scenario F are listening attentively to the performance of the musician. The scenario ends with applause after the musician finished the performance. In Scenario G, the musician has to perform in front of the conductors and some ensemble members (five men, four women) of their (fictitious) favorite ensemble, which they have applied for. They are standing in close distance to the ensemble and are being asked by the ensemble director to present two pieces successively. Scenario H is similar to scenario G with the difference that another man is talking and that the subjects are being asked to explain their motivation of applying for the ensemble, similar to a job interview. The time for playing/ singing until getting interrupted by the jury is longer in scenario G (4 min per piece) than in Scenario H (3 min per piece). Scenario I takes place in a video studio presenting a live recording for a television broadcast. After entering the video studio, the musician stands in front of a green screen illuminated by floodlights. The musician is filmed and recorded by a camera and a microphone right in front of them. The musician can see a sound engineer through a small window, who is giving them instructions during the live recording. The total duration including waiting phase is 6.75 min.
