Planned pairwise comparisons confirmed that parameter R was significantly increased for red exemplars compared to blue [χ 2 (1) = 18.02, p < 0.001] and green exemplars [χ 2 (1) = 27.76, p < 0.001], and there was a slight trend for R being higher for red compared to yellow exemplars [χ 2 (1) = 2.71, p = 0.100].
