Humans perceive ratios for different spatial magnitudes such as length, area, and numerosity, and temporal magnitudes such as duration. Previous studies have shown that spatial ratios may be processed by a common ratio processing system. The aim of the current study was to determine whether ratios across spatial and temporal domains may also be processed by a common system. Two hundred and seventy-five participants completed a series of spatial and temporal ratio estimation and magnitude discrimination tasks. Structural equation modeling (SEM) was used to analyze the relationship between ratio processing across domains when controlling for absolute magnitude processing ability. Results showed a significant relationship between spatial and temporal ratio processing. Absolute magnitude processing was also shown to explain a large part of the variance in both spatial and temporal ratio processing factors. These results have implications for theories of general magnitude processing for both absolute and relative magnitudes. |
