The ability to perceive moving objects is crucial for threat identification and survival. Recent neuroimaging evidence has shown that goal-directed movement is an important element of object processing in the brain. However, prior work has primarily used moving stimuli that are also animate, making it difficult to disentangle the effect of movement from aliveness or animacy in representational categorisation. In the current study, we investigated the relationship between how the brain processes movement and aliveness by including stimuli that are alive but still (e.g., plants), and stimuli that are not alive but move (e.g., waves). We examined electroencephalographic (EEG) data recorded while participants viewed static images of moving or non-moving objects that were either natural or artificial. Participants classified the images according to aliveness, or according to capacity for movement. Movement explained significant variance in the neural data over and above that of aliveness, showing that capacity for movement is an important dimension in the representation of visual objects in humans.
感知移动物体的能力对于识别威胁和生存至关重要。最近的神经影像学证据表明，目标导向的运动是大脑中物体处理的一个重要元素。然而，之前的工作主要使用了也是有生命的移动物体作为刺激，这使得很难将运动的影响与有生命或有活力从代表性分类中区分开来。在当前的研究中，我们通过包括有生命但静止的刺激物（例如植物）和无生命但移动的刺激物（例如波浪）来研究大脑处理运动和有生命的关系。我们记录了参与者观看移动或静止的自然或人为物体的静态图像时的脑电图（EEG）数据。参与者根据有生命或运动能力对图像进行分类。运动在神经数据中的解释超过了有生命的解释，表明运动能力是人类对视觉物体的表现的一个重要维度。
