Visual perception of objects requires the integration of separate independent stimulus features, such as object identity and location. We ask whether the location and the identity of an object are processed with different efficiency for being consciously recognized and reported. Participants viewed a target letter at one out of several locations that were terminated by pattern masks at all possible locations. Participants reported the location of the target and/or its letter identity. Report performance as a function of the target duration before the mask is enabled to estimate the speed of visual processing and the minimum duration for processing to start. Visual processing was faster and started earlier for spatial location than for object identity, even though the processing of the features was (stochastically) independent. Together, these findings reveal an intrinsic preference of the human visual system for the perceptual processing of space as opposed to visual features such as categorical identity.
对物体的视觉感知需要整合单独的独立刺激特征，例如物体的身份和位置。我们探讨对于有意识地识别和报告而言，物体的位置和身份是否以不同的效率进行处理。参与者在几个位置中的一个位置观看目标字母，所有可能位置都会被图案掩蔽终止。参与者报告目标的位置和/或其字母身份。根据掩蔽启用前目标持续时间的函数来报告表现，以估计视觉处理的速度和处理开始的最短持续时间。尽管特征的处理是（随机）独立的，但空间位置的视觉处理比物体身份的视觉处理更快且开始得更早。这些发现共同揭示了人类视觉系统对空间感知处理的内在偏好，而非对诸如类别身份等视觉特征的偏好。
