Multiple regression analyses in artificial-grammar learning : the importance of control groups
- In artificial-grammar learning, it is crucial to ensure that above-chance performance in the test stage is due to learning in the training stage but not due to judgemental biases. Here we argue that multiple regression analysis call be successfully combined with the use of control groups to assess whether participants were able to transfer knowledge acquired during training where making judgements about test stimuli. We compared the regression weights of judgements in a transfer condition (training and test strings were constructed by the same grammar but with different letters) with those in a control condition. Predictors were identical in both conditions-judgements of control participants were treated as if they were based oil knowledge gained in a standard training stage. The results of this experiment as well as reanalyses of a former study support the usefulness of our approach.
