Experiment 1 | 89 | 149 | 709 | 754 |
Experiment 2 | 106 | 125 | 759 | 821 |
Experiment 3 | 117 | 188 | 858 | 914 |
Note: In the lure drift model, drift rate for lures freely varied across test strength with the starting point held constant. In the starting point model, drift rate for lures was fixed across strength and starting point bias was free to vary. Each model had 12 free parameters to fit 44 freely varying response frequencies. There were 19 participants in Experiment 1, 20 in Experiment 2, and 21 in Experiment 3 (all data are from the mixed condition).
