Question

Quizplus · Accepted Answer

Experimenter bias and participant expectancies can become similar in some experiments because both involve the experimenter or participant inadvertently affecting the outcome of the study through their own biases or expectations. Regression toward the mean refers to the tendency for extreme scores to move toward the average on subsequent measurements, and maturation refers to the natural developmental changes that occur over time. Attrition refers to the loss of participants from a study over time. None of these factors are related to experimenter bias in the same way as participant expectancies.
