Table 1.
The eight conditions in the decision-making task where participants have to chose between playing a control gamble or an experimental gamble
| Proportionate Choice Trials | |||
|---|---|---|---|
| Trial number | Probability | Expected gains | Expected losses |
| 1 | High (60%) | Large (70) | Large (70) |
| 2 | Small (30) | ||
| 3 | Small (30) | Large (70) | |
| 4 | Small (30) | ||
| 5 | Low (40%) | Large (70) | Large (70) |
| 6 | Small (30) | ||
| 7 | Small (30) | Large (70) | |
| 8 | Small (30) | ||
The control gamble predicts a 0.5 probability of winning and a 0.5 probability of losing ten credits. Experimental gambles vary in the probability of losing/winning, the amount of expected gains and the amount of expected losses, yielding a total of eight trial types
