Mean Correct Response Times and Proportion Error Rates for Probe Displays in Experiment 1
| Position of target |
|||||
|---|---|---|---|---|---|
| Type of trial | Never | Rare | Medium | Frequent | Average |
| Control | 400 | 394 | 388 | 406 | 397 |
| (.05) | (.04) | (.04) | (.04) | (.04) | |
| Negative prime | 433 | 423 | 433 | 429 | |
| (.07) | (.04) | (.05) | (.05) | ||
| Negative-prime effect | -38 | -34.5 | -23.5 | -32 | |
| (-.02) | (.00) | (-.02) | (-.02) | ||
| Repeated target | 417 | 404 | 410 | 423 | 414 |
| (.06) | (.03) | (.05) | (.05) | (.05) | |
| No prime distractor | 393 | 407 | 401 | 404 | 403 |
| (.02) | (.04) | (.03) | (.02) | (.03) | |
| Average per location | 403.3 | 409.5 | 405.5 | 416.5 | 410.8 |
| (.04) | (.05) | (.04) | (.04) | (.04) | |
Note. Response times (RTs) are expressed in milliseconds. Error rates appear in parentheses. Position of target is defined by the frequency of distractor appearance in a location. The negative RTs and error rates for the negative-prime effect are calculated by taking the difference between the control and negative-prime trials for the corresponding response measures.
