I am not aware of any research information that pertains to this issue so I would like to what everyone's thought of this subject is.
Aside from mannerism and user name, the avatar is one of the key elements of the first impression of judgement others used towards an individual regardless of it is true or not. To give an example, my own avatar depicts of a player in a sandbox platform game called Terraria by Redigit indicate that I appreciate it enough to place it in my own avatar.
Even correlation that are more disconnected from the person that uses the avatar has even the faintest connection, if only that they know of the subject of the picture, just find the picture appealing. Not many people will depict themselves with an avatar that they have a strong dislike for.
I would like some thoughts on this subject. Thank you for replying to this.
