Brain Development: Can Teaching Make a
Difference?
It has long been known that different regions of the brain have specialized functions. For example, the frontal lobes are involved in abstract reasoning and planning, while the posterior lobes are involved in vision. Until recently, it was believed that these specialized regions developed from a genetic blueprint that determined the structure and function of specific areas of the brain. That is, particular areas of the brain were designed for processing certain kinds of information from birth.
New evidence suggests that the brain is much more malleable than previously thought. Recent findings indicate that the specialized functions of specific regions of the brain are not fixed at birth but are shaped by experience and learning. To use a computer analogy, we now think that the young brain is like a computer with incredibly sophisticated hardwiring, but no software. The software of the brain, like the software of desktop computers, harnesses the exceptional processing capacity of the brain in the service of specialized functions, like vision, smell, and language. All individuals have to acquire or develop their own software in order to harness the processing power of the brain with which they are born.
A number of studies support this view. However, all were carried out on animals, because it is not possible to do such research with humans. Caution is called for when extrapolating these findings to humans.
These findings may have implications for language educators: for one thing, that teaching and teachers can make a difference in brain development, and that they shouldn’t give up on older language learners.

The core modal verbs in English are “can”, “could”, “may”, “might”, “shall”, “should”, “will”, “would”, and “must”. Their use obeys some syntactic restrictions. Which of the following alternatives presents an incorrect example of the use of a modal verb?
