Three experiments employed a metacontrast masking procedure to examine the extent and nature of priming effects from visual stimuli not consciously perceived. The results showed effects of unconscious stimuli on subsequent target responses that (1) were more consistent, reliable, and not subject to strategic control, as compared with consciously perceived stimuli (Experiment 1); (2) produced both facilitation and interference of subsequent processing (Experiment 2); and (3) did not influence indirect response-related levels of processing (Experiment 3). These results demonstrate that color and form attributes of unconscious stimuli are sufficiently registered within the visual system to influence behavior, and that some of these unconscious effects occur at early levels of stimulus encoding, prior to higher level perceptual and response-related processes.

在元对比遮罩中无意识地处理颜色和形式。

三个实验采用了元对比掩盖程序，以检查没有自觉觉察到的视觉刺激引发效应的程度和性质。结果表明，与有意识的刺激相比，无意识的刺激对后续目标反应的影响（1）与有意识的刺激相比更加一致，可靠且不受策略控制（实验1）；（2）产生了促进和干扰后续加工的效果（实验2）；（3）不影响与响应相关的间接处理水平（实验3）。这些结果表明，无意识刺激的颜色和形式属性已在视觉系统中充分记录下来，以影响行为，并且其中一些无意识效应发生在早期的刺激编码水平，
