Regression of d2 on d1, condition (Async, Sync) and Q4 (Drifting Forward).

	Coefficient	SE	t	P	Partial η2
Constant	−0.19	0.10	−1.79	0.086
Main Effect: Sync	0.21	0.11	1.81	0.083	0.12
d1	1.14	0.15	7.65	0.000	0.71
Main Effect Q4	0.08	0.02	3.50	0.002	0.34
Main Effect Q7	0.06	0.05	1.27	0.218	0.06
Interaction: Sync.Q7	−0.16	0.06	−2.62	0.015	0.22

Overall F_{(5, 24)} = 15.50, P < 0.00005, R² = 0.76. Shapiro-Wilk test for normality of residual errors has P > 0.62. Sync = 0 is asynchronous and Sync = 1 is synchronous. The interaction term Sync.Q7 = 0 for asynchronous and Q7 for synchronous.
