研究了短时重复启动范式中的空间、时间和注意操作。短启动产生了强烈的偏好选择启动的替代品，而长启动有相反的效果。然而，第二个简短的介绍了一个长的启动产生了偏好的启动词，尽管长的总启动持续时间。这些令人惊讶的结果解释了一个计算模型，假定源混淆（主要功能与目标功能混淆）和折扣（从启动功能的证据被打折）的抵消组件。作者通过展示这些成分如何通过不同的启动显着性操作进行合作或竞争，获得了令人信服的证据。该模型允许之间的分离启动的显着性和幅度，从而提供了一个统一的帐户“阈下”和“阈上”启动。
The authors investigated spatial, temporal, and attentional manipulations in a short-term repetition priming paradigm. Brief primes produced a strong preference to choose the primed alternative, whereas long primes had the opposite effect. However, a 2nd brief presentation of a long prime produced a preference for the primed word despite the long total prime duration. These surprising results are explained by a computational model that posits the offsetting components of source confusion (prime features are confused with target features) and discounting (evidence from primed features is discounted). The authors obtained compelling evidence for these components by showing how they can cooperate or compete through different manipulations of prime salience. The model allows for dissociations between prime salience and the magnitude of priming, thereby providing a unified account of “subliminal” and “supraliminal” priming.
