Influence of Parents and Peers on Identity

Influence of Parents and Peers on Identity

Adolescence is a pivotal period of identity formation, during which individuals begin to answer questions central to their sense of self, such as "Who am I?" and "Who do I hope to become?" Both parents and peers play critical roles in guiding adolescents through this complex developmental phase.
Parental Influence on Identity Development
Parents serve as primary guides and managers in an adolescent's life, offering support instrumental in decision-making and personal growth. This guiding role...

Bystander Effect

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Bullying

Bullying

A modern 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 interactions among children that has become a national concern is bullying.

Social Traps

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned more cows, the larger...

Self-Presentation: Self-Monitoring and Self-Handicapping

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...

Summary

Peer passengers increase teen driver crash risk through distraction and risk-taking. Male teens with passengers engaged in risky behaviors, while females were distracted by interior activities, especially with opposite-gender passengers.

Area of Science:

Traffic safety research
Adolescent driver behavior
Crash causation analysis

Background:

Teen drivers face elevated crash risks.
Peer passengers are a known contributing factor.
Mechanisms include distraction and risk-taking.

Purpose of the Study:

Investigate how peer passengers affect teen driver crash risk.
Differentiate mechanisms for male and female drivers.
Examine driver-passenger gender combinations.

Main Methods:

Analyzed National Motor Vehicle Crash Causation Survey data (2005-2007).
Sampled 677 drivers aged 16-18 in serious crashes.
Compared precrash factors for teens with and without passengers.

Main Results:

Males with passengers: increased aggressive acts and illegal maneuvers.
Males with passengers: higher risk of exterior distraction.
Females with passengers: increased interior non-driving activities, especially with opposite-gender passengers.

Conclusions:

Passengers influence male teen crashes via distraction and risk-taking.
Females are primarily affected by internal distraction.
Findings can inform passenger-related crash prevention strategies.
