BBiosocial Effect
CExperimental Bias ✓ Correct
DParticipant Bias
Correct answer: (C) Experimental Bias — The researcher unintentionally affecting participants is experimental bias, so that is the answer.
Explanation
★The researcher unintentionally affecting participants is experimental bias, so that is the answer.
★Experimental bias is the researcher's subtle, unintended influence on participants.
★It can distort how participants behave during the study.
★This obscures the true effect of the independent variable.
★The Hawthorne effect is participants changing behaviour because they know they are watched.
★Biosocial and participant bias describe other influences, not this researcher effect.
