This course aims to inform students about methodological and design issues in planning and conducting psychological experiments. The course will walk through the steps involved in designing an experiment from planning, writing research proposal for ethical approval, selecting stimuli, doing manipulation check, writing program for data collection, and sorting and analysing pilot data. After taking this course, students should be able to design a psychological experiment on their own. Students are assumed to have basic knowledge of the scientific methods and different research designs prior to taking this course, and so SS2033 or equivalent is the prerequisite. This course focuses on hands-on laboratory skills in experimental set up, basic programming skills (e.g., e-prime, Inquisit, etc.) for creating an experiment program, and principles of using the eye tracker device in psychological experiments.
