Representational Momentum Transcends Motion
通过七个实验发现，大脑对变化的自动预测不仅扭曲对运动的记忆，也会扭曲对亮度、色彩饱和度等非运动变化的记忆，但色调变化除外，这揭示了知觉、认知和记忆的内在机制。
To navigate the world, our minds must represent not only how things are now (perception) but also how they are about to be (prediction). However, perception and prediction blur together for objects in motion, a classic finding known as "representational momentum." If you glance at a photo of a person diving into a lake, you will tend to remember them closer to the water than they really were. In seven experiments (with adult participants from the United States) we show that this phenomenon transcends motion: Our minds make predictions that distort our memories about changes that involve no motion whatsoever, including changes in brightness, color saturation, and proportion. Additionally, we use representational momentum to map the limits of automatic prediction, showing that there are no analogous effects for changes in hue. Our automatic predictions distort our memories in many domains-not just motion-and the presence or absence of these distortions expose the inner workings of perception, cognition, and memory.
