Answer:
Sensory adaptation
Explanation:
Sensory adaptation is a reduction in sensitivity to a stimulus after constant exposure to it. This is the term that psychologists would use to describe Janelle's situation. In Janelle's case, she is insensitive to the fact that she is wearing the hat because she has gotten used to having it and therefore does not feel it anymore. Sensory adaptation, however, also allows us to free up our attention and resources to focus on other less common stimuli around us.
