Time is an important aspect of the issue of nuclear waste, both from a technical and from a perceptional perspective. Previous studies have investigated the relationship between time and risk perception of nuclear waste, applying the discounting paradigm and therefore limiting time
to one very narrow aspect: its duration. However, time is a multifaceted concept and encompasses more than a linear property. The aim of our study is to test the influence of a different aspect of time, namely temporal representations (linear or cyclical) on risk perception of nuclear waste.
In an experimental study we demonstrate that both linear and cyclical representations have a reducing effect on risk perception compared to the control condition, where no specific time representation was activated. Examining group differences, we also demonstrate that temporal representations
have a differing influence depending on whether participants have a stable belief about nuclear waste or whether they belong to an ambivalent group that does not yet hold a stable belief. Furthermore, we replicate the well-documented gender gap in risk perception. Our results bear potentially
interesting implications for risk communication by demonstrating a causal relationship between the graphic representation of time and risk perception of nuclear waste.
