Effects of Light Reflection on Spatial Visualization Ability and implications for Engineering Technology Students

Petros Katsioloudis, Mildred Jones


Results from a number of studies indicate that the type of light generated by the reflection on the surface of different types of surfaces can influence the spatial visualization ability; however, research provides in¬consistent results. Considering this, a quasi-experimental study was conducted to identify the existence of statistically significant effects on spatial visualization ability as measured by the Mental Cutting Test and Sectional View drawing ability due to the impacts of light reflection. In particular, the study compared three types of light reflection; mirror, specular and diffuse and whether a significant difference exists among engineering technology students. According to the results of this study it is suggested that the type of light reflection provides statistically significant differences.
