The relative magnitude (or intensity) of an event can have direct implications on timing estimation. Previous studies have found that greater magnitude stimuli are often reported as longer in duration than lesser magnitudes, including Arabic digits (Xuan, Zhang, He, & Chen, 2007). One explanation for these findings is that different quantitative dimensions (size, intensity, number) are processed and represented according to a common analog magnitude system (Walsh, 2003). In the current study, we examined whether there were commonalities in how people judge the intervals of time occurring between discrete stimuli of different magnitudes across a variety of quantitative dimensions, which included number, size, and color saturation. It was found that duration judgments increased systematically as the overall magnitude difference between sequentially presented stimuli increased. This finding was robust against manipulations to the direction of the sequence, or whether the sequence followed ordered (continuous) or nonordered (discontinuous) pattern trajectories.
