Time is a fundamental and intangible part of human existence. It is commonly described as a measurement of intervals and durations. However, time is also a deeply subjective experience that is shaped by individual perception processes. Beyond being a cognitive phenomenon, time is closely connected to broader systems that encompass ecological and economic structures of society. This integrated linkage has led to varying perceptions of time throughout history that significantly differ across cultural settings. Two essential modes of time perception in this context are the linear and circular perception mode. Linear time perception views time as a sequence that is forward-moving. Events take place in a chronological order and unfold from past to present and into the future. In contrast, circular time perception represents a cyclical understanding of time. Events are experienced as a recurring rhythm, such as the changing of seasons and tides during the year.

　　This thesis explores whether the effects associated with the two time perception modes can be observed and measured. The study examines the relationship between time perception and individual decision-making, employing a serious game as an investigative tool. For this purpose, physical gameplay is combined with digital elements, including an augmented reality layer. In this way, the game creates a multimodal experience that allows participants to understand and reflect on linear and circular time perspectives. The game functions not only as an experimental platform but also as a data collection method. Through the analysis of gameplay and decision-making patterns, this research aims to highlight the influence of time perception on human behavior and cognition. The findings provide insights into the profound impact that time perception has on thought processes and actions, contributing to a deeper understanding of this essential aspect of human experience.
