Unit 5

Front

What does it mean when infant behaviors, like crying to indicate feeling sleepy or hungry, are described as probably pre-intentional?

Back

Pre-intentional behaviors are those that are not consciously directed towards a goal. Infants exhibit these behaviors instinctively, without a clear intention to communicate.

Front

Can children discriminate sounds in languages other than their native language at birth?

Back

No, children are not born with the ability to discriminate only sounds in their native language; they can initially discriminate a wide range of sounds.

Front

What are aphasias and are they only a problem with spoken language?

Back

Aphasias are language disorders that affect a person's ability to communicate. They can impact spoken language, written language, and comprehension, not just spoken language.

Front

Is it true that language symptoms observed in adults are usually the result of diffuse, distributed injury all over the brain?

Back

No, language symptoms in adults are often localized to specific areas of the brain, rather than being the result of diffuse injury.

Front

Does the size of a person's mental lexicon indicate their intelligence?

Back

No, the size of a mental lexicon does not necessarily correlate with intelligence; it reflects vocabulary knowledge rather than cognitive ability.

Front

What is the definition of pre-intentional communication in infants?

Back

Pre-intentional communication refers to behaviors that are not consciously aimed at conveying a message, such as crying or cooing.

Front

How does the ability to discriminate sounds change as children grow?

Back

As children grow, they become more attuned to the sounds of their native language and less able to discriminate sounds from other languages.

Front

What is the impact of localized brain injury on language abilities?

Back

Localized brain injury can lead to specific language deficits, such as difficulty in speaking, understanding, reading, or writing, depending on the affected area.

Front

What are some common types of aphasia?

Back

Common types of aphasia include Broca's aphasia (difficulty in speech production) and Wernicke's aphasia (difficulty in language comprehension).

Front

What role does the mental lexicon play in language processing?

Back

The mental lexicon is a mental dictionary that stores information about words, including their meanings, pronunciations, and syntactic properties, essential for language processing.
