A researcher asks participants to verify if “A frog is green” is true or false. Which prediction follows from the distributed nature of semantic memory?

D. Verification time will not depend on semantic organization but on working memory capacity.
B. Verification time will be fast because color attributes are directly linked to the representation of “frog.”

C. Real words activate L-IFG more strongly due to semantic access, while pseudo-words activate L-vPMC more due to phoneme assembly.
D. Both types activate identical pathways because reading always depends on phonological decoding.
C. Real words activate L-IFG more strongly due to semantic access, while pseudo-words activate L-vPMC more due to phoneme assembly.
