My name is Thomas Ian Vaughan-Johnston, and I am a lecturer (AKA assistant professor) who studies social psychology and methods at Cardiff University. My research tackles persuasion with a focus on vocal properties, and integrating individual differences (involving personality, the self, and lay scientific beliefs). On this website you can find my CV, research papers, and statistics resources.
