Briefly explain the relationship between participant effects, experimenter effects, single-blind experiments, and double-blind experiments
What will be an ideal response?
A participant effect is a threat to internal validity in which the participant, consciously or unconsciously, affects the results of the study. A single- or double-blind experimental procedure can help to control for this. An experimenter effect is a threat to internal validity in which the experimenter, consciously or unconsciously affects the results of the study. Single and double-blind experimental procedures can help control for this also. A single-blind procedure controls for either participant or experimenter effects whereas a double-blind procedure controls for both at the same time.
