While World Cup fans are abuzz with Uruguay forward Luis Suarez's apparent bite of an Italian defender, experts explain the psychology behind adult biting is linked to impulsive behavior.
First of all, biting isn't exclusive to Suarez, or to soccer: Remember Mike Tyson? Rugby also has a fair share of bites. Still, it's a rare act for adults. Most people learn not to bite during breastfeeding in infancy, David Wilson, a criminologist at Birmingham City University, told the BBC after Suarez bit someone else last year.
"While common in early childhood, biting in adults is rare," Eva Kimonis, senior lecturer at the School of Psychology at the University of New South Wales in Australia told Reuters. "It may be one manifestation of a broader, long-term pattern of misbehavior that involves other forms of aggression - hitting, bullying, shouting, physical fighting - and is common to people with particularly hot tempers and impulsiveness."
