Question

Annah argues that people are primarily "right brained" or "left brained". ramona argues that whether you are right brained or left brained is inherited. kristin argues that there is some specialization in the right and left hemispheres but not to the extent that has been popularly believed. who is right?

Answer 1

Kristin's perspective is the most scientifically accurate, as it acknowledges that while there is some hemispheric specialization in the brain, it is not as black-and-white as the terms 'right-brained' or 'left-brained' suggest. Both hemispheres interact to produce behaviors and functions, and the concept of hemisphere dominance has produced inconsistent results in research.

Step-by-step explanation:

The debate between Annah, Ramona, and Kristin touches on the popular myth regarding the dominance of the right brain or left brain in individuals. Kristin's argument aligns most closely with current scientific understanding. Research suggests that while there is some lateralization of function, with the left hemisphere more involved in language and the right in spatial and nonverbal reasoning, there is no strict dominance of one hemisphere for all functions. Many major functions are globally distributed throughout the cerebrum. The concept of inheriting a 'right-brained' or 'left-brained' trait does not align with modern neuroscience, and the dichotomy of 'right-brained' vs. 'left-brained' is largely considered an oversimplification of brain lateralization.

When discussing brain hemisphere interaction or dominance, the complexity is evident. For example, the left hemisphere has shown superiority in memory associations and positive emotions, while the right has shown strengths in pitch perception and negative emotions. Nonetheless, findings are not always consistent, promoting an understanding of a cooperative relationship between the hemispheres rather than dominance in behaviors. Furthermore, the phenomenon of handedness and its potential correlation with brain lateralization and dominance offers additional insight into cerebral function, as is evident from anthropological studies and neurological cases where the corpus callosum is severed, showing unique cerebral function patterns.

Answer 2

The answer is Kristin. Kristin's argument that there are specializations happening in the left and right hemisphere of the brain but the lateralization process is not definitely inconclusive and the scientists have yet to connect this to behavioral, physiological and anatomical development of the human brain is correct. Her argument was also backed up by several research studies.
