Dr. Wizard randomly assigns people to two groups. Those in the experimental group receive a "subliminal audiotape" that they are told will improve their self-esteem. The other group receives no treatment. Three weeks later Dr. Wizard interviews them and reports that people in the experimental group show higher self-esteem. What change would IMPROVE the procedure for this research?
A) Eliminate the independent variables
B) Use a convenience sample of people
C) Include more demand characteristics
D) Make the procedure double-blind
Double-blind
A study design in which neither the participants nor the researchers know which participants are receiving the experimental treatment and which are receiving a control treatment, to prevent bias.
Demand Characteristics
Aspects of an experimental setting that influence participants' behaviors or responses, potentially leading to biased results by prompting participants to act in ways they believe are congruent with the experimental goals.
Independent Variables
Factors in an experiment that are purposely manipulated or varied by the researcher to examine their effect on dependent variables.
- Identify and understand the roles of distinct experimental controls, including the double-blind study.
- Appreciate the importance of designing studies to minimize biases and expectations on the part of both experimenters and participants.
