Abstract

‘Experimenter artifacts’ and ‘subject artifacts’ are uncontrolled systematic errors that can arise within the experimental situation. Experimenter artifacts can be classified as being noninteractional or interactional. Subject artifacts can result from demand characteristics within the experimental situation and from the motivations of the subjects themselves. While there are strategies for minimizing potential artifacts, experimenters must be mindful of ethical considerations.
