I am curious at what age hand preference develops. And can you exert any influence on that development?
In particular, I would expect the influences to be somewhat counter intuitive. With things like having to use the left hand to hold a caregiver's hand in early walking preferencing the right for accessory use. At infant ages, it would be neat to see if preference of holding a baby on a side influences things.
- Technolithic 5mo agoThe introduction of this article makes reference to a couple of papers (e.g. https://doi.org/10.1038/s41598-017-16827-y https://doi.org/10.1038/s41598-017-16827-y ) that handedness is observable in utero but cautions small sample sizes for these studies.
- taeric 5mo agoRight, my question was more meant for how well established that is. And if it is open to influence. My searches made it look like it was not positive that handedness was fixed until a bit later. Still before formal schooling, but not necessarily in babies.
- markb139 5mo agoI’m a leftie from a 50% leftie family. Apparently I showed my left handedness as a baby when grasping for things and hardly used my right hand. My mother was also a leftie, but in her generation she was forced to write with her right hand. The net result being she could write equally well with both hands. When I learnt this I tried to copy it.
- taeric 5mo agoRight, I know that dexterity in a hand is largely a teachable thing. And, similarly, I don't think this is unique to hands. It is just that most people don't know what their "dominant" foot or eye are. (I'm now curious to know about dominant ears. That is almost certainly a thing?) My question is largely one of curiosity to know when the dominance fully sets in.
