Coefficient estimates and test statistics for the beta regression evaluating the association between failure of the DD attention checks and degree of discounting in Study 1.

Predictor	Coefficient	Std. Error	z	p
Intercept	−0.08	0.26	−0.32	0.750
Failing Any DD Attention Checks	0.39	0.17	2.32	0.020
Systematic DD Data [Yes]	−0.68	0.21	−3.25	0.001
DD Duration	−0.02	0.03	−0.52	0.603
DD Task Order [Second]	0.40	0.16	2.57	0.010
DD Task Order [Third]	0.08	0.15	0.57	0.567
Group [Experimental Group 1]	−0.23	0.16	−1.45	0.147
Group [Experimental Group 2]	−0.23	0.15	−1.58	0.113

Note. DD = Delay Discounting. The intercept coefficient reflects those who passed both attention checks, completed the monetary DD task first, and were assigned to the control group in the primary study from which data were drawn.
