When Researchers Investigated the Organization of Long-Term Memory, They Found

When researchers investigated the organization of long-term memory, they found that:

A) it must be linked to sound, since users of sign language don't have "tip-of-the-tongue" states.
B) verbal information is indexed semantically, and not by sound or form.
C) semantic categories help organize memories involving words and concepts.
D) the organization is based on human physiology, and so culture has few effects on retrieval.
