What defines "semantic memory" in relation to language comprehension?

Semantic memory plays a crucial role in language comprehension by serving as the mental repository for factual knowledge, concepts, and the meanings of words. This type of long-term memory enables individuals to understand the significance of language and to connect words to their meanings, which is essential for effective communication. It allows people to comprehend and convey ideas, access factual information, and relate concepts to one another.

While options mentioning visual images, emotional responses, and spatial awareness involve different types of memory and cognitive functions, they do not encapsulate the core definition of semantic memory as it relates to language comprehension. Visual images pertain more to iconic memory, emotional responses are tied to affective memory, and spatial awareness is connected to spatial memory. Thus, the definition encapsulated in the correct choice emphasizes the role of semantic memory in organizing and understanding information that is fundamental for grasping language and communication.
