“The results: The people who were allowed to gesture usually did so—and they also commonly used perceptual-motor strategies in solving the puzzles. The people whose hands were restrained, as well as those who chose not to gesture (even when allowed), used abstract, mathematical strategies much more often.
The findings evince deeper questions about the relationship of mind and body and their relationship to space, says Alibali. “As human thinkers, we use visual-spatial metaphors all the time to solve problems and conceptualize things—even in domains that don’t seem physical on their face. Adding is ‘up,’ subtracting is ‘down.’ A good mood is ‘high,’ a bad one is ‘low.’ This is the metaphoric structuring of our conceptual landscape.””
