Question 3

Areas of the brain that analyze the sounds of a word are said to be performing a __________ analysis.

Accepted Answer

Phonological analysis refers to the process of analyzing the sounds of language, such as the sounds of a word. This includes the identification and organization of phonemes, which are the smallest units of sound in a language. Therefore, the areas of the brain that analyze the sounds of a word are said to be performing a phonological analysis.

Question 4

"Broca's aphasia" and "Wernicke's aphasia" are confusing terms because

Accepted Answer

The answer of "Broca's aphasia" and "Wernicke's aphasia" are confusing...

Question 5

Early research indicated that much of the aphasia resulting from the surgical excision of Broca's area was a consequence of

Accepted Answer

Early research suggested that the aphasia observed after the surgical removal of Broca's area was largely due to temporary postsurgical edema (swelling), rather than the removal of a specific language center. This swelling could impact the function of surrounding brain areas, leading to temporary language difficulties.

Question 7

Of the 214 aphasic patients in the classic Hecaen and Angelergues's study, how many displayed disorders of language that were purely expressive (Broca's aphasia)or purely expressive (i.e., Wernicke's aphasia)?

Accepted Answer

In the study by Hecaen and Angelergues, none of the 214 aphasic patients displayed disorders of language that were purely expressive or purely receptive.

Question 8

The smallest units of sound that distinguish among various words in a language are called

Accepted Answer

Phonemes are the smallest units of sound in a language that distinguish among various words.

Question 9

The findings of the brain stimulation studies of Ojemann and colleagues suggest that language abilities might be organized in the cortex like a

Accepted Answer

The term "mosaic" is used to describe the way language abilities are organized in the cortex in the brain stimulation studies conducted by Ojemann and colleagues. This suggests that different language functions are spread out across different regions of the brain, rather than being localized in a single area.

Question 10

In contrast to the predictions of the Wernicke-Geschwind model, CT and structural MRI studies have identified aphasic patients who appear to have damage restricted to

Accepted Answer

The Wernicke-Geschwind model primarily focuses on cortical areas, but studies have shown that aphasia can also result from damage to subcortical structures like the basal ganglia, thalamus, and subcortical white matter, indicating a more complex network involved in language processing.

Question 11

Electrical stimulation of the left cerebral cortex of conscious patients can influence their speech in a variety of ways.Which of the following is not a commonly observed speech-related response to cortical stimulation? The patient

Accepted Answer

The answer of Electrical stimulation of the left cerebral cortex...

Question 12

Electrical stimulation of sites in the left neocortex of conscious human patients often

Accepted Answer

Electrical stimulation of sites in the left neocortex of conscious human patients disrupts language-related abilities, even when applied to sites outside the areas of the Wernicke-Geschwind model. Furthermore, these disruptive effects are similar at widely scattered sites and can vary between different patients, indicating that electrical stimulation effects are different at the same sites in different patients. Therefore, all of the above choices are correct.

Question 13

-According to the Wernicke-Geschwind model, when we read, the output of the angular gyrus is transmitted to

Accepted Answer

According to the Wernicke-Geschwind model, when reading, the information processed by the visual cortex is sent to the angular gyrus, which then sends the information to Wernicke's area for further processing of language comprehension.

Question 14

According to the cognitive neuroscience approach to the study of language,

Accepted Answer

The cognitive neuroscience approach to the study of language posits that constituent cognitive processes of language are localized in the brain, but the areas of the brain involved in language are not dedicated solely to that purpose. This means that language processing is likely distributed across multiple regions of the brain rather than being controlled by one large homogeneous area of cortex. Therefore, options A and B are true, but option C is false. Thus, option E (both A and B) is the best choice.

Question 15

-According to the Wernicke-Geschwind model, during speech, the output of Wernicke's area is transmitted to

Accepted Answer

According to the Wernicke-Geschwind model, the output of Wernicke's area is transmitted to Broca's area for the production of speech.

Question 16

Areas of the brain that interpret the meaning of a word are said to be performing a __________ analysis.

Accepted Answer

Semantic analysis involves interpreting the meaning of language, including individual words and larger phrases or sentences. Phonological analysis involves identifying and processing the sounds of language, while grammatical analysis involves parsing the structure of language. Phonemic analysis involves identifying the smallest units of sound in language. Serial processing refers to a step-by-step, sequential approach to information processing, but is not directly related to language analysis.

Question 17

The first large-scale cortical electrical stimulation studies of conscious human patients were conducted by

Accepted Answer

Penfield conducted the first large-scale cortical electrical stimulation studies of conscious human patients in the 1950s, mapping out various functional areas of the brain such as the motor cortex and sensory cortex.

Question 18

The results of CT and structural MRI studies of aphasic patients indicate that

Accepted Answer

The results of CT and structural MRI studies of aphasic patients show that not all aphasic patients have damage limited to the classic Wernicke-Geschwind areas, indicating a more complex relationship between brain damage and aphasia. Many aphasics indeed have extensive damage that includes subcortical white matter, not just the cortical areas traditionally associated with language. Additionally, the pattern of damage often correlates with the type of aphasia, where anterior lesions typically result in expressive deficits and posterior lesions in comprehension deficits, supporting the comprehensive statement that all of the provided options are correct.

Question 19

CT and structural MRI studies of the brains of patients with language-related disorders have found that

Accepted Answer

The answer of CT and structural MRI studies of the...

Question 20

-According to the Wernicke-Geschwind model, Broca's area contains the neural programs of

Accepted Answer

Broca's area is primarily associated with speech production and is responsible for coordinating the movements required for vocalization. It is not directly involved in language comprehension or reading, which are associated with other areas of the brain such as Wernicke's area and the visual cortex.
