We all know that there is much more to being left-handed than just writing, and a fascinating new study published today suggests that we left-handers actually do think differently. The author of the study Daniel Casasanto, goes so far as to suggest that handedness may influence our decisions on everything we do, from the cereal we buy to whom we vote for.
Using a series of studies, Casasanto found that students were more likely to associate positive ideas with their dominant side and negative ideas with their less dominant side. Casasanto believes his findings, published in the August edition of Journal of Experimental Psychology, could have important implications in education.
He says If righties write the textbook and create the exercises and set up the classrooms, they’re likely to arrange things according to this implicit â€˜right is good’ preference,â€ Casasanto said. Maybe that’s going to make learning math or going to school and sitting in the classroom just a little bit less pleasant or more disconcerting for lefties. Potentially, sensitivity to this could create better learning environments for lefties.â€
