视觉识别简要介绍的目标词的影响，存在的非诊断的启动词，立即之前的目标，侧翼词同时提出的目标附近，和视觉面具，立即跟随目标在同一位置。预充取决于持续时间：在强迫选择目标识别任务中，短启动会产生强烈的选择启动选项的偏好，而长启动则会产生相反的效果。ROUSE模型（Huber，Shiffrin，Lyle，& Ruys，Psychological Review 108：149-182，2001）通过假设主要特征与目标特征混淆，并且当两者与最佳水平进行比较时，关于主要特征的证据对于短素数折扣较少，而对于长素数折扣较多，来预测这种相互作用。在本研究中，我们增加了典型的短期启动实验，通过添加侧翼，同时出现的目标，并保持了短期或长期的持续时间。在实验中，我们复制了以前的启动效应，并产生了新的效应侧翼持续时间。ROUSE解释了引发和侧翼的发现与先前假设的过程，但不同的定量参数的侧翼：相对于最佳水平的折扣，所有的侧翼功能被低估，但较长的侧翼折扣比短的侧翼。
Visual identification of briefly presented target words is affected by the presence of nondiagnostic prime words that immediately precede the target, flanker words simultaneously presented adjacent to the target, and visual masks that immediately follow the target in the same location. Priming is duration dependent: In a forced choice target identification task, brief primes produce a strong preference to choose the primed alternative, whereas long primes have the opposite effect. The ROUSE model (Huber, Shiffrin, Lyle, & Ruys, Psychological Review 108:149-182, 2001) predicts this interaction by positing that prime features are confused with target features and that evidence regarding the prime features is discounted less for short primes and more for long primes, when both are compared with the optimal level. In the present study, we augmented the typical short-term priming experiment by adding flankers that appeared simultaneously with the target and remained for a short or long duration. In the experiment, we replicated previous priming effects and produced novel effects of flanker duration. ROUSE accounted for both the priming and flanker findings with the previously posited processes, but with different quantitative parameters for flankers: Relative to optimal levels of discounting, all flanker features were underdiscounted, but longer flankers were discounted more than short flankers.
