Table 1. The reaction times and percentage of errors in each condition, shown for target-present and target-absent trials separately. Reaction times are means ± standard errors of the mean. Error percentages are calculated as the number of errors divided by the number of trials + the number of errors*.
| Reaction times (s) | Errors (%) | |||
|---|---|---|---|---|
| present | absent | present | absent | |
| cube | 1.12 ± 0.13 | 2.36 ± 0.30 | 1 | 0 |
| sphere | 2.28 ± 0.15 | 6.11 ± 0.55 | 8 | 0 |
| rough | 1.26 ± 0.09 | 2.54 ± 0.19 | 3 | 0 |
| smooth | 3.68 ± 0.38 | 8.54 ± 0.86 | 12 | 0 |
*Percentages were rounded to integers.
