    Insights

    After-school and weekend evenings are key times for physical activity (PA) in disadvantaged children. Identifying these periods helps target interventions to increase PA levels in children.

    Area of Science:

    • Pediatric Health
    • Public Health
    • Exercise Science

    Background:

    • Focuses on physical activity (PA) patterns in 8- to 9-year-old Irish children from socially disadvantaged backgrounds.
    • Addresses the critical need to understand activity levels in vulnerable child populations.

    Purpose of the Study:

    • To investigate daily physical activity (PA) patterns in 8- to 9-year-old Irish children from socially disadvantaged areas.
    • To identify specific time blocks associated with higher PA levels.

    Main Methods:

    • Utilized ActiGraph accelerometers worn by 408 children for a minimum of 4 days.
    • Employed principal component analysis to identify distinct active time blocks on weekdays and weekends.
    • Grouped participants into sex-specific quartiles based on mean daily moderate- to vigorous-intensity PA accumulation.

    Main Results:

    • 213 children (8.7 ± 0.5 years) met accelerometer inclusion criteria.
    • 56.7% of participants achieved the recommended 60 minutes of daily moderate- to vigorous-intensity PA, with males significantly more likely than females (P < .01).
    • The largest differences in PA accumulation between the most (Q4) and least (Q1) active children occurred after school on weekdays and during weekend evenings.

    Conclusions:

    • After-school hours on weekdays and evenings on weekends are identified as crucial 'activity rich' periods.
    • These periods highlight significant disparities in PA accumulation between the most and least active disadvantaged children.
    • Findings suggest targeted interventions during these times could effectively improve PA levels in this population.

    Social Scripts

    People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

    Social Traps01:41

    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...

    Social Facilitation

    Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

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

    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...

    Social Exchange Theory02:06

    Social Exchange Theory

    We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).
