What are the Differences between Boys and Girls Attitude?

For over 50 years, researchers have been studying how boys and girls interact. Not surprisingly, they have found some differences.

For the most part, boys and girls are more similar than they are different.
A lot of girls enjoy playing computer games, and a lot of boys enjoy more friendship-centered activities.
Researchers have found, however, that as a general group, boys spend more time with boys in physical activities such as sports and games; whereas girls tend to spend more of their time socializing with other girls in more friendship-based activities (for example, talking with other girls) (1, 2, 3). So it is not surprising that boys and girls tend to bully and be bullied differently. One of the most consistent research findings is that boys are more likely to both bully and be bullied than are girls (3, 4, 5, 6, 7, 8, 9). Also, boys and girls experience different types of bullying behaviors.

Bullying is defined as a form of aggression that is repetitively exerted against an individual who feels unable to defend him/herself (10). This aggression may occur directly against someone in a physical (for example, slapping, pushing) or verbal (for example, swearing, name calling) manner. Bullying can also be indirect whereby the targeted person experiences the aggression through others (for example, gossiped about, excluded from a social activity).

How are Girls Involved in Bullying?
Through Peer Group

Girls tend to bully other girls indirectly through the peer group. Rather than bully a targeted child directly, girls more often share with other girls (and boys) hurtful information about the targeted child (4). For example, a girl may tell a group of girls an embarrassing story about another girl. They may create mean names, gossip, and come up with ways of letting the girl know that she is rejected from the peer group (for example, saying mean things about her on social networking sites such as Facebook or MySpace, using her email address to send harassing messages to everyone on her email list, texting her a death threat). These are called “relational” bullying because they attack relationships and friendships.

How are Boys Involved in Bullying?

In contrast to girls, boys of any age and ethnic group tend to be physically aggressive (e.g., hit, kick, slap, push, or punch) (1, 2, 9, 11, 14, 20). Also, research shows that physical abuse tends to occur more often among boys than girls at all educational levels (e.g., elementary, high school, college) (13, 15, 16). In addition, male college students tend to bully and be bullied through physical and verbal forms of bullying (e.g., name-calling) more often than college girls (15).

Also boys may be more accepting of bullying, than are girls (17). That is, boys may like a girl even if she bullies others and like other boys who bully. Girls may still befriend boys who bully, but tend to dislike girls who bully. At the core of these differences are children’s and, indeed, societal beliefs about acceptable behaviors for boys and girls. Many people may see bullying among boys as “just boys being boys”. So, girls may accept this attitude and tolerate boys’ bullying. However, girls may be less accepting of girls who bully if it is seen as overly aggressive.
