D Critical Thinking: Evaluating Conclusions (page 167)
Possible answers:
The conclusion that speech problems are the result of L-brain
damage is reasonable because it’s a logical conclusion based
on the available facts in Broca’s examinations. The conclusions
that the L-brain is dominant in verbal processing and that spatial
abilities are in the right brain are reasonable because they’re
based on data obtained from Sperry’s objective experiments. The
conclusion that the L-brain is the dominant half is not reasonable
because it’s fitting the information from Broca and Sperry’s
research to expectations about the most important capabilities in
the brain. The conclusion that the two halves of the brain always
work together is reasonable because it’s based on the available
facts from modern brain-mapping technologies.

1. It seemed obvious that the speech problems were a direct
result of the damage.
2. Unfortunately, the fascinating scientific discoveries of Broca,
Sperry, and others led to some less-than-scientific conclusions
about the brain in the fields of psychology and education.
3. The influence of the right-brain/left-brain model on those in the
education field was responsible for the idea that “brain-balancing”
activities could strengthen the less dominant side of the brain.
