Title: AGE DIFFERENCES IN CONJUNCTION FALLACIES AND INFORMATION PROCESSING STYLES
Author: Ma, Xiaodong
Description: Probability reasoning plays an essential role in our everyday life. The current study examined if there were age differences in conjunction fallacies and in information- processing styles. Fifty-two younger and older adults attended study 1, and they completed a lottery problem first, then the Linda conjunction problem. No age differences were discovered regarding the conjunction error (CE) rates in the Linda problem. Furthermore, an age by gender interaction effect was found for both rational and experiential thinking styles. Fifty-two younger adults attended study 2, and they were randomly assigned to two groups with each group have 26 participants. Group 1 finished the lottery problem, and then the Linda problem. Group 2 completed the lottery problem, then the revised Linda problem, which provided base rates for the two events. Results showed that the CE rates of the Linda problem of group 2 were significantly reduced comparing with those of group 1.
