In the past decade there has been an increase in research into how transgender people fit into cognitive development theory. ^[1]At the earliest, transgender children can begin to socially trasition during identity exploration, specifically during the preoperational stage. ^[2]In 2015, KR Olson and collegues studied transgender youth, who identified as their preferred gender, in comparison to their siblings and unrelated cisgender children. The students participated in the IAT, a test that measures how one may identify based off a series of questions related to memory. Overall it determines a child's predeered gender prefrenced. It showed that the transgender children's results correated with their desired gender. The behaviors of the children also related back to their results. For instance, the trangender boys enjoyed food and activites typically assosiated and enjoyed by cisgender boys. The article reports that the researchers found that the children were not confused, deceptive, or oppositional of their gender identity, and responded with actions that are typically respresented by their gender identity.

This is the sandbox page where you will draft your initial Wikipedia contribution. If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. Bibliography sandbox
