Group Behavior: Learn It 5—Aggression

Throughout this module, we have discussed how people interact and influence one another’s thoughts, feelings, and behaviors in both positive and negative ways. People can work together to achieve great things, such as helping each other in emergencies, such as the heroism displayed during the 9/11 terrorist attacks. People also can do great harm to one another, such as conforming to group norms that are immoral and obeying authority to the point of murder: consider the mass conformity of Nazis during WWII. In this section, we will discuss a negative side of human behavior—aggression.

aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental.

  • Hostile aggression is motivated by feelings of anger with the intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression.
  • Instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for hire displays instrumental aggression.

There are many different theories as to why aggression exists. One theory that explains one of the functions of human aggression is frustration-aggression theory (Dollard, Doob, Miller, Mowrer, & Sears, 1939). This theory states that when humans are prevented from achieving an important goal, they become frustrated and aggressive.

Some researchers argue that aggression serves an evolutionary function (Buss, 2004). Men are more likely than women to show aggression (Wilson & Daly, 1985). From the perspective of evolutionary psychology, human male aggression, like that in nonhuman primates, likely serves to display dominance over other males, both to protect a mate and to perpetuate the male’s genes (Figure 1). Sexual jealousy is part of male aggression; males endeavor to make sure their mates are not copulating with other males, thus ensuring their own paternity of the female’s offspring. Although aggression provides an obvious evolutionary advantage for men, women also engage in aggression. Women typically display instrumental forms of aggression, with their aggression serving as a means to an end (Dodge & Schwartz, 1997). For example, women may express their aggression covertly, for example, by communication that impairs the social standing of another person. There is little research on how aggression might vary in non-binary or transgendered individuals as perpetrators, particularly from the evolutionary perspective. However, a plethora research demonstrates the significant and highly disproportionate burden of assault, violent victimization, and bullying of this population (Langenderfer-Magruder, Walls, Kattari, Whitfield & Ramos, 2016)

Bullying

Another form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interaction among children that has become a national concern is bullying.

bullying

Bullying is repeated negative treatment of another person, often an adolescent, over time (Olweus, 1993). A one-time incident in which one child hits another child on the playground would not be considered bullying: Bullying is repeated behavior. The negative treatment typical in bullying is the attempt to inflict harm, injury, or humiliation, and bullying can include physical or verbal attacks. However, bullying doesn’t have to be physical or verbal, it can be psychological.

Bullying involves three parties: the bully, the victim, and witnesses or bystanders. The act of bullying involves an imbalance of power with the bully holding more power—physically, emotionally, and/or socially over the victim. The experience of bullying can be positive for the bully, who may enjoy a boost to self-esteem. However, there are several negative consequences of bullying for the victim, and also for the bystanders. Being the victim of bullying is associated with decreased mental health, including experiencing anxiety and depression (APA, 2010). Victims of bullying may underperform in schoolwork (Bowen, 2011). Bullying also can result in the victim committing suicide (APA, 2010).

Research finds gender differences in how girls and boys bully others (American Psychological Association, 2010; Olweus, 1993). Boys tend to engage in direct, physical aggression such as physically harming others. Girls tend to engage in indirect, social forms of aggression such as spreading rumors, ignoring, or socially isolating others. Based on what you have learned about child development and social roles, why do you think boys and girls display different types of bullying behavior?

Although there is not one single personality profile for who becomes a bully and who becomes a victim of bullying (APA, 2010), researchers have identified some patterns in children who are at a greater risk of being bullied (Olweus, 1993): Children who are emotionally reactive are at a greater risk for being bullied. Bullies may be attracted to children who get upset easily because the bully can quickly get an emotional reaction from them. Children who are different from others are likely to be targeted for bullying. Children who are overweight, cognitively impaired, or racially or ethnically different from their peer group may be at higher risk.

Gay, lesbian, bisexual, and transgender teens are at exceptionally high risk of being bullied and hurt due to their sexual orientation and/or gender identity. According to recent research from The Trevor Project (2021), over half of LGBTQ youth enrolled in middle and high school reported being bullied in the past year. LGBTQ youth are nearly twice as likely to be called names, verbally harassed, or physically assaulted at school compared to their non-LGBTQ peers. Bullying and harassment are significant risk factors for suicide, and LGTBQ youth are nearly four times as likely to attempt suicide (Johns et al., 2019). It is estimated that almost half of LGTBQ youth have considered suicide in the last year (The Trevor Project, 2022), and the social environment of these youth plays a highly influential role on mental health. Importantly, schools that are LGTBQ-affirming show a protective factor in rates of bullying, highlighting the importance of education and advocacy in this area at the institutional level. 

Cyberbullying

With the rapid growth of technology, and widely available mobile technology and social networking media, cyberbullying or online bullying is now all too common.

cyberbullying

Cyberbullying, like bullying, is repeated behavior that is intended to cause psychological or emotional harm to another person. What is unique about cyberbullying is that it is typically covert, concealed, done in private, and the bully can remain anonymous. This anonymity gives the bully power, and the victim may feel helpless, unable to escape the harassment, and unable to retaliate (Spears, Slee, Owens, & Johnson, 2009).

 

Cyberbullying can take many forms, including harassing a victim by spreading rumors, creating a website defaming the victim, and ignoring, insulting, laughing at, or teasing the victim (Spears et al., 2009).

 

In cyberbullying, it is more common for girls to be bullies and victims because cyberbullying is nonphysical and is a less direct form of bullying (Hoff & Mitchell, 2009). Interestingly, girls who become cyberbullies often have been the victims of cyberbullying at one time (Vandebosch & Van Cleemput, 2009).

The effects of cyberbullying are just as harmful as traditional bullying and include the victim feeling frustration, anger, sadness, helplessness, powerlessness, and fear. Victims will also experience lower self-esteem (Hoff & Mitchell, 2009; Spears et al., 2009). Furthermore, research suggests that both cyberbullying victims and perpetrators are more likely to experience suicidal ideation, and they are more likely to attempt suicide than individuals who have no experience with cyberbullying (Hinduja & Patchin, 2010).
