Speech is processed primarily in the right hemisphere by the of those who are left-handed and by the of those who are right-handed.

minority; minority

Explanation: "Speech is processed primarily in the right hemisphere by the minority of those who are left-handed and by the minority of those who are right-handed."

The right answer is minority in both cases because the speech is processed primarily in the left hemisphere (indentify fast sounds). The right hemisphere indentify and process the long tones, like music.

The answer for both blanks is minority. Speech is processed primarily in the right hemisphere by the minority of those who are left-handed and by the minority of those who are right-handed.

EXPLANATION

Speech is processed primarily in the right hemisphere by the minority of those who are left-handed and right-handed. It is because speech is processed mainly in the left hemisphere, not the right. Broca’s area is a region that is located in the frontal lobe, in the left part of the brain. This part of the brain is the one that produced speech.

Broca’s area has been linked to language processing because of an accident. In this accident, two patients lost their ability to speak because of an injury. There is a specific part of their brain that is injured. Because of this incident, the region of the brain that is injured is called Broca’s area. Broca’s area is specialized in speech production.  

If a person is experiencing a deficit in speech production in Broca’s area, then they are experiencing Broca’s aphasia. Broca’s aphasia is also known as expressive aphasia. Studies have also proven that chronic aphasia can make Broca’s area lose a lot of their functions, such as speech and language functions.  

Using the MRI, it is able to detect that the activation of Broca’s area is associated with a lot of language tasks. Meanwhile, the slow destruction of Broca’s area that is happening from a brain tumor can still leave the speech intact. This is because slowly the function of Broca’s area is shifting to nearby areas of the brain.
