Moving in Colour Illuminated Space: An Exploration of Analyses

This paper presents statistical results of an experiment investigating how the body moves in four different colour spectra of light across a blindfolded and non-blindfolded condition. In a light lab, 26 participants were immersed in white, blue, amber and red illumination, and asked to move around while blindfolded and non-blindfolded. Video-data of their movements were retrieved and coded by two independent researchers into eight binary movement categories of: fast/slow, up/down, hard/soft, coherent/incoherent. Intercoder reliability analysis shows satisfactory (41%), slight to fair (47%) and no (12%) agreements between the encodings. The coding chosen for further statistical analysis shows that participants moved in significantly different manners within the four lighting scenarios. No significant differences between the two conditions of blindfolding and non-blindfolding were found. These findings are in line with an earlier analysis of this study and generally appear to support the hypothesis that visual spectra of light are perceived beyond vision.
