| 1 | 21 | 15/6 | 21.2 | 2.3 | 23.1 | 3.8 | 1 for auction 21 for viewing time |
Effect of removing auditory cue |

Effect of requiring a different motor effector during training and probe |
Participants who bid less than $0.25 on over 40 items during the auction were excluded. Participants who did not view the items as instructed during training were excluded. Participants whose training ladders (which govern the go-signal-delay) did not converge (indicating erratic behavior) were excluded.
