what was the impact of culture, gender, and age diversity on this group cohesiveness?

TO REPLY A WITH A REGULAR COMMENT IN YOUR OWN WORDS. I NEEDT FOR TODAY.

In your group, there was 10 year-old Hispanic female and a 16-year old African American male, both children have a diagnosis of ADHD. Although these children are somehow similar since they both have an ADHD diagnosis, there are also very different as being from different cultural backgrounds, of different gender, and in a different age group. In your opinion, what was the impact of culture, gender, and age diversity on this group cohesiveness?
