Researchers then compute a mean PARH score and correlate this with their key effects. Significant correlations indicate that demand characteristics may be related to the research results. Nonsignificant correlations provide tentative evidence against the demand characteristics explanation. Pre-experimental questionnaires can also cause demand ...
The "good subject effect" or "participant effect", where a study participant knows what the researcher expects and will behave accordingly, is sometimes referred to as the "Orne effect".

[1] [2] The effect was discovered in the context of research conducted at the Hawthorne Western Electric plant; however, some scholars think the descriptions are fictitious.

We wanted to see what the psychological effects were of becoming a prisoner or prison guard. To do this, we decided to set up a simulated prison and then carefully note the effects of this institution on the behavior of all those within its walls. [9] A 1996 article from the Stanford News Service described the experiment goal in a more detailed ...
