Naturalistic Observations02:30

Naturalistic Observations

16.9K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

55.2K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Framing Effects

7.8K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Impact of Social Context on Individuals

220
Social psychology examines how the real or imagined presence of others influences individuals' thoughts, feelings, and behaviors. A key concept in this field is the role of social context in shaping behavior. The same individual may act differently depending on the social setting, due to the varying expectations and norms associated with each environment. This context-dependent behavior illustrates the influence of social roles, which prescribe appropriate conduct in specific situations.Social...

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...

Social Foundations of Self II: The Generalized Other

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Young adolescents spend a third of their weekday evenings on screens, with more alone time and time in the living room or bedroom linked to increased sedentary screen-time. Family-based interventions can help reduce recreational screen use.

Area of Science:

  • Public Health
  • Adolescent Health
  • Behavioral Science

Background:

  • Sedentary screen-time is a growing concern, particularly among adolescents, linked to negative health outcomes.
  • Understanding the environmental and social contexts of adolescent screen-time is crucial for effective interventions.

Purpose of the Study:

  • To determine the prevalence of sedentary screen-time in UK adolescents during after-school and weekday evening periods.
  • To investigate the relationship between contextual factors (location, social company) and screen-time in this age group.

Main Methods:

  • A three-day time-use diary was employed to capture screen-based activities of 204 UK adolescents (aged 11-12 years).
  • Data focused on weekday after-school (3-6 pm) and evening (6-10:45 pm) periods, recording activity, location, and companions.

Main Results:

  • Young adolescents dedicate approximately one-third of their weekday evening leisure time to screens, with boys exhibiting slightly higher usage.
  • Most after-school and evening time was spent with family; solitary time correlated with increased screen use.
  • Screen-time was higher when adolescents were in the living room or bedroom, and when spending more time at home.

Conclusions:

  • Family-based health promotion interventions targeting after-school and leisure-time screen use are recommended.
  • Reducing sedentary recreational screen-time behaviors in young adolescents requires addressing contextual factors within the home environment.
