Table 1 Probability associated with high rating (p(high)) for the 16 stimuli, each made up of the four binary cues (C1, C2, C3 and C4), in the multi-cue probabilistic learning task. Based on their p(high), the stimuli are further divided into two conditions: unambiguous and ambiguous
Stimulus | C1 | C2 | C3 | C4 | p(High) | Condition |
|---|---|---|---|---|---|---|
1 | 0 | 0 | 0 | 0 | 0.100 | Unambiguous |
2 | 0 | 0 | 0 | 1 | 0.133 | Unambiguous |
3 | 0 | 0 | 1 | 0 | 0.166 | Unambiguous |
4 | 0 | 1 | 0 | 0 | 0.200 | Unambiguous |
5 | 1 | 0 | 0 | 0 | 0.400 | Ambiguous |
6 | 1 | 0 | 0 | 1 | 0.429 | Ambiguous |
7 | 1 | 0 | 1 | 0 | 0.458 | Ambiguous |
8 | 1 | 1 | 0 | 0 | 0.487 | Ambiguous |
