The Psychology of AI studies how artificial intelligence systems behave and how people perceive, interpret and act on that behaviour. Because such systems cannot in general be understood by reading their programs, the department knows them the way a naturalist knows an animal: by careful observation and controlled experiment. Its students learn when a confident answer means something and when it doesn’t, how the framing of a question changes the answer, how to recognise fluent nonsense, and how to avoid both reading a mind into a machine and dismissing it as “just autocomplete”. It is a scientific skill, not a technical one, and it is taught here from Elementary School to Graduate Diploma, in tutorials with scholar-simulacra and in laboratory work on real AI systems.
