TY - JOUR A1 - Oberauer, Klaus A1 - Weidenfeld, Andrea A1 - Hornig, R. T1 - Logical reasoning and probabilities: A comprehensive test of Oaksford and Chater (2001) N2 - We report two experiments testing a central prediction of the probabilistic account of reasoning provided by Oaksford and Chater (2001): Acceptance of standard conditional inferences, card choices in the Wason selection task, and quantifiers chosen for conclusions from syllogisms should vary as a function of the frequency of the concepts involved. Frequency was manipulated by a probability-learning phase preceding the reasoning tasks to simulate natural sampling. The effects predicted by Oaksford and Chater (2001) were not obtained with any of the three paradigms Y1 - 2004 SN - 1069-9384 ER -
