Correlations Between Parameter Values and Data for Individual Subjects

Parameter	1	2	3	4	5	6
1. Mean a	1.00	—
2. Ter	.05	1.00	—
3. Mean v	−.38	−.53	1.00	—
4. Accuracy	−.43	−.63	.86	1.00	—
5. Mean RT	.77	.58	−.77	−.77	1.00	—
6. Mean error RT	.90	.40	−.61	−.61	.94	1.00

Note. a = average boundary separation for speed and accuracy conditions; T_er = nondecision component of response time (RT); v = mean of the four drift rates for the four stimulus duration conditions. A single correlation of .22 would be significant at a .05 level.
