For a clue to the answers to those questions, let's look at some more research on the body-specificity hypothesis. Abstract from "Different Bodies, Different Minds: The body-specificity of language and thought" (Current Directions in Psychological Science):
Do people with different kinds of bodies think differently? According to the body-specificity hypothesis (Casasanto 2009), they should. In this article, I review evidence that right- and left-handers, who perform actions in systematically different ways, use correspondingly different areas of the brain for imagining actions and representing the meanings of action verbs. Beyond concrete actions, the way people use their hands also influences the way they represent abstract ideas with positive and negative emotional valence like “goodness,” “honesty,” and “intelligence,” and how they communicate about them in spontaneous speech and gesture. Changing how people use their right and left hands can cause them to think differently, suggesting that motoric differences between right- and left-handers are not merely correlated with cognitive differences. Body-specific patterns of motor experience shape the way we think, communicate, and make decisions.
