主观经验表明，心理状态是离散的，在某种意义上，记忆和感知在某些情况下很容易出现在脑海中，但在其他情况下完全无法意识到。然而，心理物理学研究的悠久历史表明，心理状态的离散性质在很大程度上是副现象的，心理过程的强度不断变化。我们使用了一种新颖的行为方法学组合来研究复杂图像感知的潜在过程：（1）接收器操作特性（ROC）分析，（2）变化检测闪烁范式的修改，以及（3）意识体验的主观报告。这些方法产生了趋同的结果表明，知觉判断反映了两个过程的组合，但功能独立，贡献有意识的经验：有意识知觉的状态过程和强度过程的认识;过程，对应于回忆和熟悉的长期记忆。此外，从知觉实验的见解导致了一个新的回忆现象的发现，在长期记忆变化检测范式。主观经验和认知理论之间的明显不相容性可以在一个统一的状态强度框架内理解，该框架将意识与认知联系在感知和记忆的各个领域。
Subjective experience indicates that mental states are discrete, in the sense that memories and perceptions readily come to mind in some cases, but are entirely unavailable to awareness in others. However, a long history of psychophysical research has indicated that the discrete nature of mental states is largely epiphenomenal and that mental processes vary continuously in strength. We used a novel combination of behavioral methodologies to examine the processes underlying perception of complex images: (1) analysis of receiver operating characteristics (ROCs), (2) a modification of the change-detection flicker paradigm, and (3) subjective reports of conscious experience. These methods yielded converging results showing that perceptual judgments reflect the combined, yet functionally independent, contributions of two processes available to conscious experience: a state process of conscious perception and a strength process of knowing; processes that correspond to recollection and familiarity in long-term memory. In addition, insights from the perception experiments led to the discovery of a new recollection phenomenon in a long-term memory change detection paradigm. The apparent incompatibility between subjective experience and theories of cognition can be understood within a unified state-strength framework that links consciousness to cognition across the domains of perception and memory.
