Measuring learning using an untrained control group: Comment on R. Reber and Perruchet
Abstract:R. Reber and Perruchet (this issue) argue that use of control groups without training is unsound for establishing that learning has occurred. We show that inferring learning from a difference between a trained group and an untrained control in no way relies on their implausible additivity assumption, and that untrained control groups can be an invaluable aid to the researcher.
