Sigal is a popular music singer and songwriter. In her MA thesis she collected data from popular music singers (mostly from Israel and Italy ) regarding their experience of Music Performance Anxiety (MPA). She was especially interested in MPA factors that might be specific to this group such as somatic symptoms related to the singing apparatus (dryness in the mouth, difficulty in breathing etc.), the use of microphone and amplification, and performing with their own material. She found that these factors indeed play a special role though not necessarily in the expected direction. For example, performing with their own music increased their experience of flow and decreased their MPA. In addition, she showed that attitude towards stress is a significant factor in MPA.
