This paper provides an overview of the idea of decision research and related experimental methods. Decision research in social psychology is described briefly as the general term for descriptive theories to explain the psychological knowledge related to people's decision-making behavior. As the studies of S. Asch, S. Milgram, H. A. Simon, and D. Kahneman suggest, the experimental methodology and knowledge of decision research have been applied widely in such fields as economics, business administration, and engineering, and are expected to become useful in the future. This paper explains various experimental methods and data analysis methods related to research in decision-making processes, and introduces utility measurement, estimation of probability weighting functions, conjoint measurements, process tracing techniques, and preference measurements using incentive compatibility techniques. It ends with discussion section of the experimental methods in decision research.
