People With Creative Personalities Really Do See the World Differently
Evening light exposure to computer screens disrupts human sleep, biological rhythms, and attention abilities.

Zitat:We wanted to test whether openness is linked to a phenomenon in visual perception called binocular rivalry. This occurs when two different images are presented to each eye simultaneously, such as a red patch to the right eye and a green patch to the left eye.
For the observer, the images seem to flip intermittently from one to the other. At one moment only the green patch is perceived, and at the next moment only the red patch – each stimulus appearing to rival the other (see illustration below).
Intriguingly, participants in binocular rivalry studies occasionally see a fused or scrambled combination of both images (see middle frame, above). These moments of ‘rivalry suppression’, when both images become consciously accessible at once, seem almost like a ‘creative’ solution to the problem presented by the two incompatible stimuli.
Across three experiments, we found that open people saw the fused or scrambled images for longer periods than the average person. Furthermore, they reported seeing this for even longer when experiencing a positive mood state similar to those that are known to boost creativity.

Zitat:Each morning, participants filled out questionnaires and conducted a computerized attention task. Irrespective of light intensity, SWL illumination significantly disrupted sleep continuity and architecture and led to greater self-reported daytime sleepiness. SWL light also altered biological rhythms, subduing the normal nocturnal decline in body temperature and dampening nocturnal melatonin secretion. Light intensity seemed to independently affect sleep as well, but to a lesser degree. Both light intensity and wavelength negatively affected morning attention. In sum, light wavelength seems to have a greater influence than light intensity on sleep and a wide-range of biological and behavioral functions. Given the widespread use of electronic devices today, our findings suggest that screen light exposure at evening may have detrimental effects on human health and performance.
