Abstract
The Golden Ratio (GR) is deeply related to visual perception and cognition in psychology. The previous studies indicated that the inverted GR plays a part in human performance. We investigated a decision-making when participants had no prior information and had to choose one of identical cells located in a column. This condition forces participants to use their implicit primordial knowledge. The results showed that frequencies with which participants selected each cell could be described by the functions of the GR (GR-proportions). The GR-proportions constantly occurred through out the experimental conditions. This suggests the unique mechanism producing the GR-proportions underlying the process of decision-making. Therefore, we conclude that discovered functions of the GR are intrinsic to human implicit primordial knowledge.
