Final answer:
Julia is using olfactory bulb, sensory adaptation, and difference threshold to settle into her new apartment. The concepts of top-down processing explain her actions.
Step-by-step explanation:
Julia is using olfactory bulb when she lights a vanilla-scented candle in her apartment, as the olfactory bulb is responsible for processing smells. She is also using sensory adaptation when she no longer notices the flashing light outside her window after a while, as sensory adaptation refers to the decreased sensitivity to a constant stimulus over time. Additionally, she is using difference threshold when choosing between two shades of blue for her bedroom, as the difference threshold refers to the minimum difference between two stimuli that can be detected.
Julia's actions can be explained by top-down processing, as she initially perceives the coat in the corner of the room as a man due to her expectations and prior knowledge. She then corrects her perception based on the actual information available. There is no mention of feature detection or dark adaptation in the scenario.
