最近的研究表明，受试者可能会在早期平行阶段或后期聚焦阶段对视觉信息做出反应，并且相关阶段的选择是数据驱动的。使用噪声兼容性范式，我们测试了这一假设，即这种选择也可能是战略和背景驱动的。在这个范例中观察到的干扰效应的至少一部分是由于在并行处理阶段的响应激活。我们在4个实验中操纵了受试者对兼容和不兼容噪音的预期，并有效地调节了干扰效应。结果表明，预期的相对效用的信息提取在平行和集中的阶段确定哪个阶段是用来激活反应。
Recent studies indicate that subjects may respond to visual information during either an early parallel phase or a later focused phase and that the selection of the relevant phase is data driven. Using the noise-compatibility paradigm, we tested the hypothesis that this selection may also be strategic and context driven. At least part of the interference effect observed in this paradigm is due to response activation during the parallel-processing phase. We manipulated subjects' expectancies for compatible and incompatible noise in 4 experiments and effectively modulated the interference effect. The results suggest that expectancies about the relative utility of the information extracted during the parallel and focused phases determine which phase is used to activate responses.
