Expected Value Choices and Weighting Functions.

<p>(A) Median percentage of choices of the option with the higher expected value, separately for the affect-rich and the affect-poor problems. In each box, the central mark is the median, the edges of the box are the 25th and 75th percentiles, and the whiskers extend to the most extreme data points. (B) Cumulative prospect theory’s weighting function fitted to the choices in the affect-poor and affect-rich problems (here, using the average parameter values across all participants; <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0122475#pone.0122475.t001" target="_blank">Table 1</a>). Probability levels used in the experiment are shaded. The dotted line indicates identity of probabilities and decision weights.
