Psychological Research on the Net is a fantastic meta-list of online psychology experiments. Most experiments disappear once the researchers meet their requirements, so lists like this one are essential to find out what’s new (and also, in a way, what’s hot in research). Sponsored the by Hanover College Psychological Department, this list does a great job at keeping up to date. They categorize studies into Mental Health, Personality, Positive Psychology, Psychology and Religion, Sensation and Perception, Sexuality, Social Psychology, Sport Psychology, Neuropsychology, Cognition, Consumer Psychology, Developmental Psychology, Emotions, Forensic Psych, Health Psychology, Industrial/Organizational, Decisions, Linguistics, General, and if that’s not enough, another long list of other meta-lists.
