Answer 1

Answer:

Participant demand

Explanation:

Participant demand also known as demand characteristic occurs when a participant in an experiment interpretes experiment's purpose and forms or subconsciously adjusts behaviour during experiment to suit this interpretation. This is an extraneous variable that could alter experiment results. It was studied and pioneered by Martin Orne.
