视觉物体启动和动作启动都有独立的报道，但两者之间的相互作用在很大程度上仍未被探索。在这里，我们使用一种新型的SFM刺激——三维螺旋来研究这个问题，发现模糊螺旋的运动方向感知可能会被之前的SFM刺激的运动方向所偏置，这是一种经典的运动启动效应。然而，运动启动的有效性取决于物体启动：中性物体启动产生弱运动启动，一致物体启动导致强运动启动，关键的是，不一致物体启动消除并压制了运动启动。相比之下，单独的物体启动（在没有运动重叠的情况下）对运动感知的偏倚影响很小。综上所述，三维SFM刺激的运动和结构存在一个完整的神经表征，三维SFM刺激的运动启动可能发生在MT/V5（非形状选择性）和LO（侧枕，非运动选择性）之间的中间阶段。这种新型的刺激，三维螺旋，以及启动-目标范式，因此可能提供一种独特的工具来研究潜在的三维SFM刺激和知觉启动的神经基础。
Both visual object priming and motion priming have been reported independently, but the interactions between the two are still largely unexplored. Here we investigated this question using a novel type of SFM stimuli, 3-D helixes, and found that the motion direction perception of an ambiguous helix can be biased by the motion direction of a preceding SFM stimulus – a classic motion priming effect. However, the effectiveness of motion priming depends on object priming: a neutral object priming produced a weak motion priming, a congruent object priming led to a strong motion priming, and critically, an incongruent object priming abolished and overpowered the motion priming. In contrast, object priming alone (in the absence of motion overlap) had little effects biasing motion perception. Taken together, these results suggest that there exists an integrated neural representation of motion and structure of 3-D SFM stimuli, and motion priming of 3-D SFM stimuli might happen at an intermediate stage between MT/V5 (which is not shape selective) and LO (lateral occipital, which is not motion selective). This novel type of stimuli, 3-D helixes, along with the prime–target paradigm, thus might offer a unique tool to examine neural bases underlying the perception of 3-D SFM stimuli and perceptual priming.
