Hyperbolic mixed-effects model results for group differences in social discounting.

N = 77	b	SE	95% CI	T	P
Level 1
v 1, mean amount to forgo for N = 1	76.06a	1.56	73.01, 79.12	48.70	<0.0001
logk, mean discounting rate	−4.52a	0.43	−5.35, −3.69	−10.67	<0.0001
Level 2
LKM controls >Wait-list controls	0.13	0.60	−1.05, 1.31	0.21	0.830
Altruists >Wait-list controls	−1.65b	0.67	−2.96, −0.33	−2.45	0.015

Note. b represents unstandardized coefficients. 95% CI indicates lower/upper limits of a confidence interval. Groups are indicator variables relative to the reference group (wait-list controls).

^a P < 0.001.

^b P < 0.05.
