Table 1.
Mean (SD) response times and distractor indices (in ms) in each experimental condition.
| Condition | Distractor present | Distractor absent | Distraction index | t | dz | p |
|---|---|---|---|---|---|---|
| Low frequency | ||||||
| Positive | 529 (71) | 509 (58) | 20 (30) | 3.7** | 0.70 | <0.001 |
| Neutral | 526 (68) | 516 (63) | 10 (19) | 3.0* | 0.53 | 0.003 |
| Negative | 539 (89) | 522 (77) | 17 (34) | 2.7* | 0.50 | 0.006 |
| High frequency | ||||||
| Positive | 525 (82) | 526 (78) | −1 (18) | 0.28 | 0.06 | 0.391 |
| Neutral | 532 (80) | 531 (78) | 1 (19) | 3.0 | 0.05 | 0.442 |
| Negative | 527 (81) | 529 (81) | −2 (16) | 0.50 | 0.13 | 0.309 |
Note: t, dz, and p-values refer to the comparison of distractor present and distractor absent trials in each condition. dz are effect sizes for within-subject comparisons (Lakens, 2013). *p < 0.05, **p < 0.001.
