Table 1.

Predictions from the diffusion model for primed and unprimed words as a function of boundary separation.

Boundary separation (a)	Primed mean RT (ms)	Unprimed mean RT (ms)	Priming effect (ms)	Primed accuracy	Unprimed accuracy
0.08	596	605	9	.795	.710
0.15	751	789	38	.858	.763
0.25	948	1025	77	.878	.775

Note. The parameter values for the predicted values were, starting point, z = a/2, nondecision component of response time, T_er = 500 ms, standard deviation in drift across trials, η = 0.25, range of the distribution of starting point, s_z = 0.05, proportion of contaminants, p_o = 0.002, range of the distribution of nondecision times, s_t = 200 ms, unprimed drift rate, v₁ = 0.2, and primed drift rate v₂ = 0.3.
