Question

The most accurate conclusion that can be drawn from research on the brain is that

a. only creative people can use both hemispheres equally.
b. most people use the right hemisphere more often than the left hemisphere.
c. the activities of both hemispheres of the brain combine to produce most behaviors.
d. normal people can be taught to use one hemisphere at a time."

Answer 1

The most accurate conclusion from brain hemisphere research is that both hemispheres combine to produce most behaviors, versus being dominated by one hemisphere or the other.

Step-by-step explanation:

Research on the brain indicates that the most accurate conclusion regarding hemispheric functions is that c. the activities of both hemispheres of the brain combine to produce most behaviors. While there is some degree of hemispheric dominance for certain tasks, such as language being more concentrated in the left hemisphere for most people, and spatial abilities and nonverbal reasoning more concentrated in the right hemisphere, these functions are not operated by one hemisphere exclusively. The interaction of both hemispheres is essential for complex behaviors, which refutes the oversimplified notion of individuals being strictly 'right-brained' or 'left-brained'.

Furthermore, lesions to the corpus callosum, seen in patients with split-brain syndrome, have shown that separating the two cerebral hemispheres can have significant effects on behavior and cognition. Such individuals can perform independent tasks simultaneously with each hemisphere, a feat not possible in individuals with an intact corpus callosum. This further underscores the complexity of hemispheric interplay and the collaborative nature of cerebral functions.
