Sensory and nervous system receives energy from the environment. In particular temporal context can have contrastive effects repelling perception away from the interpretation of the context stimulus and attractive effects TCEs whereby perception repeats upon successive presentations of the same stimulus. These expectations also called prior beliefs help us make sense of what we are perceiving in the present based on similar past experiences.
