Here's some context. I work in a museum and part of my job involved giving tours to people of all ages (preschoolers, adults and so on).

I've been here long enough to notice a common thread in the social dynamics of different groups. One very common one is the most obvious amongst kids.

There tends to be one kid in each group who will repeatedly give and demand extra attention from the tour guide (whether it be me or my coworkers).

This can come in the form of being eager to get more high fives than the other kids in the group, being more outspoken than the other kids in terms of answering questions, cracking jokes, or straight up hugging the tour guide's hand whenever they can. It's weird because they tend to choose guides of the opposite gender to show this behavior to.

The common thread is they usually wear the most attention-drawing clothing (whether it be the brightest sweater, or having a sweater while the others do not)

Could this be an early developmental sign of a queen bee or alpha male mindset? Is it a sign of neediness? A 'popular' or 'people person' in development? What factors result in them developing in this manner, and why is it that there is consistently 1 in the entire group (if they exist in the group)?

I am quite confused because it seems to be a recurring thing even for high school students and beyond (although it's much less obvious, they can still show this in outspokenness or choice of clothing color).
