Both kids who are bullied and who bully others may have serious, lasting problems. The child who is doing the bullying must meet certain characteristics in order for it to be considered bullying: physically harassing another student (shoving or hitting), taunting (teasing) or continuous mental abuse (being harassed so much that the victim feels depressed) or a deliberate exclusion from a group for the purpose of humiliation.
Cyberbullying.
Ahlfors (2010) defines cyberbullying as an aggressive, intentional act carried out against a victim by an individual or group of individuals by means of real time methods such as social networks, cell phones, instant messaging or e-mail. This type of bullying goes beyond traditional bullying in that the victim is constantly harassed and can be humiliated for all the world to see instead of just in front of their classmates. Some bullies use this method to hide behind technology to torment their victim, this is something that probably they wouldn't have the nerve to do face-to-face and they are able to stay anonymous so that the victim doesn't know who their tormentor is. .
Victim.
An individual who is on the receiving end of aggressive behavior from other individuals that would include but not limited to teasing, physical abuse and humiliation. The victim usually has a low self-esteem and is deemed weaker and unable to fight back and this is why they are picked.
Bystander Empathy.
This is where those that are around when an incident happens whether violent or verbal, fails to render aid to the victim because there are other individuals around. Sometimes it is a fear of the aggressor turning on them for intervening, not knowing what to do to help or even thinking that someone else in the group will help the victim. Either way nothing happens to help the victim and the bystanders end up being witnesses to the event with the knowledge that they could've stepped in but didn't.
