Table 5.

Mean reaction times for judgments during the study period

Task	Control	Shift, repeat	Shift, new	Switch cost
Size	1336 (33)	1405 (29)	1626 (33)	221^a (18)
Animacy	1319 (34)	1414 (32)	1578 (35)	164^a (18)
Combined	1328 (33)	1409 (30)	1601 (33)	192^a (15)

Note. These data are from the judgments in the behavioral data from the source-manipulation experiment; the CMR model did not simulate these judgments. Reaction times are reported in milliseconds and are followed by standard error of subject means. Shift, repeat refers to items in the task-shift condition where the encoding task is the same as that for the preceding item. Shift, new refers to items in the task-shift condition where the encoding task is different from the preceding item.

Significant at p < 0.0001 (t-test).
