Associations between Case Fatality Rates and Self-Reported Fear of Neoplasms and Circulatory Diseases.

According to decision by sampling theory, people store relative frequencies of events in memory, and these values constitute subjective representations of events. Because fear is a natural response to the threat of death, we hypothesized that case fatality rate (CFR) statistics, which represent how deadly a disease is, would be positively correlated with self-reported fear ratings of neoplasms and circulatory diseases. Participants ( = 239) were asked to rate various neoplasms and circulatory diseases (110 diseases in total) on fear, typicality, and disgust scales (e.

Does Fear Increase Search Effort in More Numerate People? An Experimental Study Investigating Information Acquisition in a Decision From Experience Task.

The aim of this study was to investigate the effect of numeracy and the emotion of fear on the decision-making process. While previous research demonstrated that these factors are independently related to search effort, search policy and choice in a decision from experience task, less is known about how their interaction contributes to processing information under uncertainty. We attempted to address this problem and to fill this gap.
