Table 1. A summary of mean response latencies (in ms).
| Younger adults | Older adults | |||
| Distractor-absent | Distractor-present | Distractor-absent | Distractor-present | |
| Redundant-target | 390 (51) | 406 (58) | 445 (54) | 454 (50) |
| Fastest single-target | 396 (52) | 419 (55) | 451 (57) | 480 (52) |
| No-target | 491 (63) | 505 (71) | 577 (103) | 594 (100) |
| Average RT | 422 (53) | 442 (59) | 484 (57) | 507 (55) |
| RTE | 6*** | 13*** | 6*** | 26*** |
| RTE log-transform | 0.006*** | 0.015*** | 0.005*** | 0.024*** |
*** p <0.001, RTE = RT(faster single-target) – RT(double-target). Note: Fastest single-target was calculated individually for each participant and then averaged across all participants in the task and age-group; Average RT is the average of all trials across participants in the task and age-group. Standard deviations are presented in parentheses.
