The mean percentage of choices of each symbol for both conditions (95% confidence intervals) at (a) 0-minutes, (b) 30-minutes, (c) 24-hours. The value of the symbol is the sum of the probability multiplied by the value of each outcome (i.e. 80% chance of loss (−1) and 20% chance of nothing (0) gives −80%). There were no significant effects of time or drug across the phases, nor any differences between drug and placebo conditions the 24-hour test (p > 0.05, BF01 > 1).
