Inherent threat perception of geometric 3D shapes

My name is Tim Gannetoft and I am a Swedish game development student currently writing my bachelor's thesis at the University of Skövde. This study aims to find out if different geometrical shapes can make an environment seem more or less threatening.

You will be shown four different forest environments, each with a different geometric shape as a basis. The only thing that will change in each environment will be the geometric shapes. The colouration and lighting in the environments will not change.

The survey will take about 5-10 minutes and your answers will be anonymous.
