Summary
This study synthesized motivation in Korean physical activity contexts using expectancy-value theory. Findings show motivation is influenced by various factors and impacts engagement, highlighting cultural nuances.
Area of Science:
- Psychology
- Physical Activity and Health
- Sociocultural Studies
Background:
- Expectancy-value theory is a key framework for understanding motivation.
- Motivation is influenced by cultural context and is specific to situations.
- Research on motivation in physical activity contexts is growing.
Purpose of the Study:
- To synthesize determinants and outcomes of motivation in Korean physical activity contexts.
- To apply a meta-analytic approach guided by expectancy-value theory.
Main Methods:
- A comprehensive literature search was conducted following the PRISMA statement.
- Data from included studies were extracted and analyzed using meta-analysis in R software.
- Analyses included heterogeneity testing, publication bias assessment, and subgroup analysis.
Main Results:
- Moderate-to-strong effects were found between motivation, its determinants, and outcomes.
- Internal/external factors (e.g., motivational constructs, social context, task difficulty) shape motivation.
- Self-perceptions influence expectancy beliefs and are outcomes of task values.
Conclusions:
- Findings suggest both universal and culturally specific aspects of expectancy-value theory in physical activity.
- Motivation in Korean physical activity contexts is shaped by a complex interplay of factors.
- Understanding these mechanisms can inform interventions to enhance physical activity engagement.

01:52Regression Toward the Mean
6.8K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

01:24Sources of Self-Esteem II: Performance Feedback
187
Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem:...

01:17Factors Affecting Activity Coefficient
1.5K
The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size.
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a...

01:27Drive-Reduction Theory: Push Theory of Motivation
1.1K
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...

01:29Self-Evaluation Maintenance Model
281
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

01:26Self-Esteem and Culture
204
Self-esteem, a core psychological construct, is intricately shaped by cultural context and varies significantly between collectivist and individualistic societies. In collectivist cultures such as Japan, self-esteem tends to be flexible, context-sensitive, and influenced by relationships. A Japanese student, for instance, may show restraint in formal settings like school but behave more openly among close friends, reflecting the flexible and dynamic nature of self-concept in such...
