This unit is the second and final foundational unit of the course. While PSY401 Theories of Personality provides a conceptual overview of psychology, this unit provides an applied introduction to the scientific approach that characterises the discipline. Students are introduced to modern approaches to critical thinking and scientific enquiry in psychology. Unit topics include the logic and practice of statistical inference, research design and analysis, and contemporary issues in the science of psychology. After this unit, students will be able to design a study, collect and analyse data and provide sound practical interpretations of results.
