When identifying an object, we take into account its surroundings. For example, when we see an elongated object in the bathroom we might think it is a toothbrush even if we only have a quick glance. However, in the kitchen we would not anticipate that same object. This integration between objects and scenes happens in the visual part of the brain after 250 milliseconds.
