Final answer:
In theatre, actors are expected to continue their performance without interruptions despite unexpected events, but ethical considerations in experiments or concerns about safety allow participants to refuse continuation if necessary.
Step-by-step explanation:
The statement 'Under no conditions can participants hesitate, start and stop, self-correct or otherwise momentarily interrupt the skill during scenarios' is generally a fact when it comes to theatrical performances. In theatre, the show must go on without interruption from start to finish. Performers are expected to maintain the illusion of the story without pauses or do-overs, and they must retain the details of their performance throughout. If they encounter an unexpected event, such as a late entrance or a cell phone ringing, they are trained to stay in character and react in a way that is true to the play.
However, if someone believes a task is unsafe, they have the right to speak up and refuse to participate. The priority should always be the safety and well-being of everyone involved. When it comes to actual scenarios, such as psychological experiments or data collection, integrity and adherence to ethical standards are non-negotiable. It is never acceptable to fake data or continue with an experiment if it causes genuine distress or harm to participants, as was infamously demonstrated in the obedience studies conducted by psychologist Stanley Milgram.
