The primary effect is that of learning: consistent with Bandura's (1986) social cognitive theory, much evidence shows that children learn from positive and negative televised role models, and acquire norms and standards for conduct through media outlets such as television and video games.
Personalization of a character makes a child more likely to nurture the character, and thus more likely to form a parasocial relationship that would improve learning from videos featuring the character (Calvert, Richards, & Kent, 2014).
