Twin study finds genetics affects where children look, shaping mental development

In this article a study is done on a set of twins to determine if genetics plays a role in how people adapt to their environment. This was an important study case because the first step the infant makes with interacting with their environment is eye exploration before they are able to walk. Indiana University and Karolinska Institute studied 466 children, 233 twins. 119 twins were identical and 114 were fraternal from ages 9 to 14. These children were given 80 snapshots of things that they would see in everyday life including people, an eye tracker was used to calculate the eye movements in time and space. A lot of eye exploration was also calculated. The study showed that identical twins had very similar eye exploration for fraternal twins it also showed similar eye exploration but it was weaker than identical twins.

This article relates to genetics because the results of the study demonstrated that genes do have a big part in immediate visual information. Both different types of twins had very similar eye exploration and how they adapted to their environment. A person’s genetics determines how a person sees their environment. In conclusion this article suggest that genetics and the environment intertwine together.
