Table 4. Reaction-time effects.
Activations for response time related effects for conceptual judgments for number and object names together and numbers > object names in Analysis 1 (RTs modeled separately for numbers and object names) and for conceptual judgments for number and object names together in Analysis 2 (RTs modeled over number & object names).
