Document Summary
Participant recruitment from: subject pool vs. general population, easier to get people from a subject pool; people are already signed up" here to participate in experiments, harder in a general population, voluntary vs. involuntary. Involuntary can be from studies where you are observing the population, or mandatory studies that people have to be involved in (ex: government consensus" that people need to fill out: advertisements vs. personal appeals. Helps reduce experimenter effects (i. e. nose) such as: biases, expectations, social effects, multiple experimenters. Writing down word for word exactly what has to be said. Removing as much control from the experimenter. Allows to reduce the effects of the experimenters. Standardizing protocols: create a written protocol of experimenters role, everything the experimenter has to do / say from the time ps come into the lab until the time that they leave. Create standard instructions for participants to read: an independent source of instructions that do not come from the experimenter.
