| 要旨 |
| Two experiments investigated the cognitive biases in dating of public events. In the experiment 1, using 45 public events as materials, there was the suggestion of possibility that subjects had used the accessibility heuristics, an intuitive dating strategy that subjects inferred from the accessibility of memory concerning the event. Then the current authors hypothesized that the biases would be varied as a function of the activation level of memory for events. In the experiment 2, manipulating the activation level of 4 well-known events, the hypothesis was supported. However, the results of experiment 2 did not show a relation between the accuracy of dating and the activation level. In conclusion, it was showed that 1) the accessibility heuristics were used in dating process, and that 2) the fact 1) did not always contribute to the accuracy of dating. |
