Whether someone is a morning person or a night person can have a significant influence on their perception. Generally, morning people tend to prefer the daylight hours and are more productive and alert during the morning and early afternoon. In contrast, night people tend to be more productive and alert during the evening and night hours. This difference in preference can affect how an individual perceives and processes information, with morning people being better able to focus and process information during the day, and night people being better able to focus and process information during the night.
