Idk about scientifically, but I’ve had spiders at my place that seemed like they had different personalities. For example, one was smaller but liked to traverse around and build lots of webs. He’d disappear and turn up in another corner of the room. He tried all the corners except for the one by the shower cuz it was too wet. Kinda spazzy. I called him Napoleon. Meanwhile there was another spider (same species) in the room that was super chill, just hanging out on the same web for months. Not bothered by anything, even when Napoleon built a web in his corner. I dubbed this one The Dude lol
