摘要

Results from previous studies (St. John & Risser, 2007, 2009) indicate the addition of a simplecognitive secondary task may mitigate vigilance decrements for a sustained attention taskinvolving target acquisition. The effectiveness of the cognitive task increased when its onset wastriggered by physiological indicators of inattention. The current study examined thegeneralizability of this methodology with a few modifications. A no intervention condition wasadded to provide a baseline and a short perceptual vigilance task (AVT) was added to examine theconstruct validity of the experimental task (ET). Finally, instead of using physiological indicatorsto trigger the intervention, a schedule was used that resembled that of the physiologicalintervention. Although vigilance decrements were observed for both the AVT and ET, only aweak relationship was observed between the two tasks. ET performance was not affected by thecognitive intervention. The weak relationship between the AVT and ET scores suggests that theyare not measuring the same constructs. Further, the failure to replicate previous findings castsdoubts on the robustness of the cognitive intervention for mitigating performance decrements onreal-world tasks, especially when its onset is not linked with physiological indicators ofinattention.
