Table 1.

A. Means and Standard Deviations for Accuracy and RTs (in milliseconds) in attention tasks in each of the Attention groups in Experiment 1.

Group	Proportion Correct	RTs (ms)
DA with Item task	0.94 (0.04)	1165 (205)
DA with Relational task	0.74 (0.04)	1347 (142)
DA with Item task, Harder	0.75 (0.14)	769 (41)

B. Means and Standard Deviations of memory RTs (millisecond) in the Item memory and Relational memory Tests in each of the Attention groups in Experiment 1.
Group	Item Memory	Relational Memory

Full attention	1483 (316)	1555 (318)
DA with Item task	1605 (221)	1593 (181)
DA with Relational task	1578 (278)	1448 (254)
DA with Item task, Harder	1559 (399)	1456 (271)

Note: DA, Divided attention; Numbers in the parenthesis indicate standard deviation.
