Table 2.

Individual items for the Monetary Choice Questionnaire used for the probability discounting task. The log h-values are the natural logarithm of the original h-values. The items were delivered in a random order. CS = certain-smaller; UL = uncertain-larger. Items 28–30 were catch trials in which the reward chances were both 100% but the CS and UL magnitudes differed.
