Stefan has volunteered to participate in an experiment studying vision. He has agreed to wear a pair of glasses that invert his vision. Due to perceptual _____, after about a week, he is able to perform his usual tasks, like riding a bike or reading a book.

Adaptation

Sensory analysis starts at the receptors and works to integrate the sensory information in the brain. This process is called:

Bottom-up.
