Quizplus · Accepted Answer

Demand characteristics are subtle cues or signals expressed by the researcher that communicates the kind of response or behavior that is expected from the participant, which can potentially bias the results of the study. Practice effects refer to changes in the participant's behavior due to repeated exposure to the same task, treatment effects refer to the effects of the intervention or treatment being tested, and main effects refer to the overall effect of a particular variable on the outcome of interest.
