Question

Quizplus · Accepted Answer

The presence of the researcher is manipulated by the experimenters and is therefore an independent variable. The researchers are interested in the effect of the researcher's presence on the participants' emotional expression while they watch the film clips, which makes it an experimental variable. It is not a control variable as it is not being held constant throughout the experiment. It is also not a dependent variable as it is not being measured or influenced by any other variable in the study.
