ScienceDaily (Oct. 25, 2010) — We are all aware that a bright day may lift our mood. However the brain mechanisms involved in such effects of light are largely unknown

"Invisible Pink Unicorns are beings of great spiritual power. We know this because they are capable of being invisible and pink at the same time. Like all religions, the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can't see them."

Zo zie je maar weer hoe feiten verdraaid worden:

Repeated-measures ANOVA on emotional
valence scores attributed to the stimuli after the fMRI session
with prosody (anger, neutral) and light condition (blue, green) in
which these stimuli were presented during task 1 as within-subject
factors confirmed a significant main effect of prosody, with more
negative values for anger stimulation [F(1,16) = 93.69; P < 10−6]
but no main effect of light condition [F(1,16) = 0.36; P = 0.56]
nor interaction between prosody and light conditions [F(1,16) =
0.75; P = 0.4; Fig. 2C in main text].


En even later:

In addition to our main objective, which was to investigate the
impact of the wavelength of the ambient light context, this experiment
attempted to investigate irradiance impact on brain
activity using two ambient light levels for each wavelength.

Results of the analyses including
irradiance as a factor are reported here for completeness
but cannot be considered as reliable, for two main reasons.


Met als conclusie:

Analyses of
the irradiance factor yielded no clear results. The results could be
taken to indicate that green light has a lower impact than blue
light irrespective of the irradiance level, supporting the involvement
of the nonclassical photoreception system at both irradiances.
This seems consistent with the results of the other study
that we reanalyzed. Finally, on the basis of these results, one may
speculate that, with ambient blue light exposure, low irradiance
has a higher impact than high irradiance, perhaps supporting an
involvement of rods at lower light levels.

Dus waar komt dan vandaan dat blauw licht meer invloed heeft op emoties?
That which can be asserted without evidence can be dismissed without evidence.

Tja, Philips is momenteel testen aan het uitvoeren met middelbare scholen, waar ze lampen installeren die van warmtekleur kunnen veranderen door het aantal Herz te veranderen. Er zit blijkbaar wel wat, in het veranderen van de warmtekleur.

Ik krijg altijd een beetje mijn twijfels als de producent van een product (Philips) zélf met een onderzoek komt dat laat zien hoe geweldig dat product is.
