SNARC and MARC effect estimates based on a multiple regression analysis across all three groups taken together

Group	Non-standardized SNARC slope			Non-standardized MARC effect
	Mean	SD	Test against 0	Mean	SD	Test against 0
M	−1.66	5.92	t 13 = −1.05, p = .157	−4.80	57.97	t 13 = −0.31, p = .381
E	−4.82	5.99	t 14 = −3.12, p = .004	−22.11	57.13	t 14 = −1.50, p = .078
C	−8.46	8.17	t 14 = −4.01, p < .001	−39.21	82.34	t 14 = −1.84, p = .043

Slopes were tested against 0 with one-sample t tests (one-sided, for negative values), results of which are also presented in the table
