Text: In contrast, promethazine impaired critical flicker fusion thresholds (F [3, 63] = 5. 37, P = 0. 0023) ; increased recognition reaction time (F [3, 63] = 13. 63, P < 0. 0001) and total reaction time (F [3, 63] = 12. 23, P < 0. 0001) components of the choice reaction time test ; reduced tracking accuracy (F [3, 63] = 14. 25, P < 0. 0001) and increased reaction times to peripheral stimuli (F [3, 63] = 9. 29, P < 0. 0001) in the compensatory tracking task ; reduced the number of valid responses (F [3, 63] = 14. 86, P < 0. 0001) and impaired reaction times (F [3, 63] = 12. 02, P < 0. 0001) in the rapid visual information-processing task test ; and impaired subjective ratings of sedation (F [3, 63] = 7. 55, P = 0. 0002), compared with placebo.
