我们对形状、方向和大小如何在意识内外加工的理解是有限的，需要进一步调查。因此，我们调查是否可以通过阈下加工预先呈现的刺激的影响的基本对象特征的视觉辨别。视觉掩蔽用于使刺激感知上不可见。三个实验检查是否可见和不可见的启动可以促进随后的特征区分可见目标。这些实验的不同之处在于参与者必须做出的感知辨别。也就是说，参与者被要求区分视觉刺激的形式，方向或大小的基础上。在所有三个实验中，我们证明了可靠的启动效果时，启动是可见的，但不是当启动是不可见的。我们的研究结果强调了有意识的意识在促进基本物体特征的知觉辨别方面的重要性。
Our understanding of how form, orientation and size are processed within and outside of awareness is limited and requires further investigation. Therefore, we investigated whether or not the visual discrimination of basic object features can be influenced by subliminal processing of stimuli presented beforehand. Visual masking was used to render stimuli perceptually invisible. Three experiments examined if visible and invisible primes could facilitate the subsequent feature discrimination of visible targets. The experiments differed in the kind of perceptual discrimination that participants had to make. Namely, participants were asked to discriminate visual stimuli on the basis of their form, orientation, or size. In all three experiments, we demonstrated reliable priming effects when the primes were visible but not when the primes were made invisible. Our findings underscore the importance of conscious awareness in facilitating the perceptual discrimination of basic object features.
