This study continues a string of research into the relationship between conflict detection and metacognitive judgments. For high conflict tasks we observed longer response times and lower levels of confidence. Our current research introduces images into the base-rate task. We used a simple base-rate task, e.g.: “Person A is tall”, followed by group information “The group consists of 850 basketball players, and 150 physicians”. Participants have to choose the subgroup from which the person was most likely randomly chosen. The base rate can be consistent or inconsistent with the intuitive answer. In one set of situations the image represented a base rate consistent or inconsistent with the intuitive answer, and in the second set, the image was accompanied by the usual base rate number (multi-modal situation). In the second set of situations the image was an equivalent representation of the ratio, or it was designed to mitigate the base rate by representing a 60% decrease in the ratio. In both of these situations base rates and images were in conflict with intuitive responses. Consequently, four distinct levels of conflict were induced before participants (N=35) made their decisions. After each decision participants made a judgment of confidence ranging from 50% (guessing) to 100% (complete confidence). As expected, one-way ANOVA showed a significant effect of conflict level on response times (F(3, 102)=6.71, p |
