Four experiments are presented that show that selections in Wason's (1966) four-card selection task can be increased by increasing the probability that cards will yield important outcomes. Experiment 4 also shows that selections can be influenced by varying the utilities of possible outcomes. These results suggest that some important content effects in this task may not arise from inferential processes, and examples are given of how probabilities and utilities have been confounded with other… CONTINUE READING
