Question 1

How do we know what words mean?

Answer 1

Semantic networks are networks of unitary nodes and labeled links between them, organizing based on semantic relatedness or distance.

Question 2

What are some problems with semantic networks?

Answer 2

Semantic networks face a definition problem as necessary and sufficient conditions for definitions are hard to find, leading to difficulties in learning and understanding meaning.

Question 3

How does meaning influence sentence comprehension?

Answer 3

Both world knowledge and world meaning are integrated simultaneously during sentence comprehension, eliciting similar brain responses.

Question 4

What is Broca’s aphasia?

Answer 4

Broca’s aphasia is characterized by preserved comprehension but deficits in language production, where individuals struggle to articulate speech despite knowing what they want to say.

Question 5

What is Wernicke’s aphasia?

Answer 5

Wernicke’s aphasia involves impaired comprehension but fluent yet meaningless speech production, where individuals can speak fluently but the content lacks coherence.

Question 6

Which brain regions underlie syntactic comprehension?

Answer 6

Syntactic comprehension involves Broca’s and Wernicke’s areas, along with other brain regions contributing to language processing.
