TABLE 2.

Mean ranks and chi-square values for perceptual effects for tangible priming.

	unsafe	middle	safe	χ2 (2)	p	perceptual effect as spring stiffness increased
Speed	2	2.4	1.7	7.0	.03	(mixed) lower speed
Steering	1.6	2.2	2.2	6.6	.04	Improved steering
Durability	1.7	2	2.3	6.9	.03	Improved durability
Safety	1.7	2	2.3	8.0	.02	Improved safety

Higher ranks for steering, durability, and safety are considered “better” and higher ranks for speed are considered “faster”. For example, safe is considered the slowest with better steering and durability than unsafe. All listed values are p < .05. Omitted variables are n.s. (mixed) indicates that the middle condition was not the midpoint of the 3 conditions.
