Summary
Adolescents in unsupervised peer settings showed more risky behaviors. Paid work and sports participation in out-of-school time (OST) were linked to better self-identity and work orientation.
Area of Science:
- Adolescent Development
- Sociology of Youth
- Psychology of Behavior
Background:
- Research often studies adolescent out-of-school time (OST) settings in isolation.
- Understanding the diverse impacts of various OST settings on adolescent development is crucial.
Purpose of the Study:
- To examine the relationship between time spent in four distinct OST settings and adolescent functioning.
- To investigate how unsupervised peer time, paid employment, sports, and organized activities influence development at age 15 and end of high school.
Main Methods:
- Employed individual fixed effects analyses to rigorously control for selection bias.
- Analyzed data on adolescent functioning across multiple OST settings and developmental stages.
Main Results:
- Increased unsupervised peer time correlated with higher risky and externalizing behaviors.
- Increased paid employment was associated with enhanced work orientation and self-identity.
- Participation in organized sports predicted greater positive self-identity.
Conclusions:
- Different out-of-school time settings have distinct effects on adolescent functioning.
- Considering multiple OST contexts and selection effects is vital for a comprehensive understanding of adolescent development.

Timing and Consequences on Behavior
432
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Cognitive Development During Adolescence
646
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

What is Behavior?
10.3K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Erikson's Theory on Socioemotional Development during Adolescence
1.3K
Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and "What is my place in...

Revisionist Views of Adolescent and Adult Cognition
316
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Behaviorism
5.3K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...
