ഒരു വേദിയിൽ അല്ലെങ്കിൽ ഒരു കൂട്ടത്തിനു മുന്നിൽ വച്ച് താൻ ഉദ്ദേശിച്ച കാര്യം പ്രകടിപ്പിക്കുമ്പോൾ ഉണ്ടാകുന്ന വിറ, ഭയം, ആകാംഷ എന്നിവയെ സഭാകമ്പം എന്ന് പറയുന്നു.

Stage fright or performance anxiety is the anxiety, fear, or persistent phobia that may be aroused in an individual by the requirement to perform in front of an audience, real or imagined, whether actually or potentially. Performing in front of an unknown audience can cause significantly more anxiety than performing in front of familiar faces. In some cases, the person will suffer no such fright from this, while they might suffer from not knowing who they're performing to. In some cases, stage fright may be a part of a larger pattern of social phobia, but many people experience stage fright without any wider problems. Quite often, stage fright arises in a mere anticipation of a performance, often a long time ahead. It has numerous manifestations: stuttering, tachycardia, tremor in the hands and legs, sweaty hands, facial nerve tics, dry mouth, and dizziness.
