Unconscious Processes Studies of spatial neglect and blindsight provide evidence of unconscious processing. Spatial neglect is a tendency of persons who have right hemispheric damage to ignore information and sensations affecting the left side of the body. Blindsight is found in individuals who suffer from cortical blindness. They respond to visual stimuli though they will report not being consciousness of them. Ex.

Circadian Rhythms Are you are morning person, or an evening person? Human beings seem to fall on a continuum: morning people, evening people, or no distinct preference. Where you fall on the continuum seems to have a relationship to age. Young adults likely to be “evening” people Older adults likely to be “morning” people This difference is even found in performance differences in laboratory rats (Winocur & Hasher, 1999.)
