Which of the following statements regarding semantic memories is true?
A)Different patterns of activity in the cerebral cortex are correlated with various types of semantic memories.
B)A tool labeling task is associated with activity in the visual cortex of the occipital lobe,suggesting that we think about what a tool looks like in order to name it.
C)Damage to the prefrontal cortex can produce a condition known as source amnesia of certain semantic memories.
D)An animal naming task activates areas associated with hand movements,suggesting that we think about touching an animal in order to name one.

Question

Quizplus · Accepted Answer

Different patterns of activity in the cerebral cortex have been observed in various semantic memory tasks, suggesting that different types of semantic memories are represented in different neural circuits.

Answer: B 
 The tool labeling task has been associated with activity in the visual cortex of the occipital lobe, indicating that visual information plays a role in naming tools.

Answer: C 
 Damage to the prefrontal cortex has been linked to source amnesia for certain types of semantic memories, which means that individuals have difficulty remembering where or how they learned specific information.

Answer: D 
 An animal naming task has been shown to activate areas associated with language processing rather than hand movements, suggesting that accessing semantic knowledge about animals is primarily a linguistic process.
