Ryan and Deci's Self-Determination Theory01:17

Ryan and Deci's Self-Determination Theory

20.7K
Self-Determination Theory (SDT), formulated by Richard Ryan and Edward Deci, explains that human motivation is driven by three fundamental psychological needs: autonomy, competence, and relatedness. When these needs are met, individuals experience personal growth, intrinsic motivation, and overall well-being.
Autonomy is the need to feel in control of one's actions and decisions. For example, a student who chooses their research topic is likely to be more engaged and motivated than one who...

Drive-Reduction Theory: Push Theory of Motivation

1.5K
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...

Incentive Theory: Pull Theory of Motivation

1.2K
Incentive theory, or the "pull theory" of motivation, suggests that external rewards primarily drive behavior. Individuals are motivated to engage in activities when they anticipate a desirable outcome. This is why people often work hard for promotions or study intensively to achieve high grades. These incentives can be tangible, physical rewards such as money or promotions, or intangible, non-physical rewards like praise and social recognition.
The theory differentiates between...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Motivational Cycle01:20

Motivational Cycle

1.4K
The motivational cycle is a key concept that explains how individuals are motivated to meet their needs. At its core, the cycle revolves around four distinct stages: need, drive, goal-directed behavior, and goal achievement. These stages respond to imbalances in the body or mind, prompting actions that restore balance.
The cycle begins with a need. This need can arise from various conditions, such as hunger, thirst, or temperature changes. For instance, when an individual feels cold, their body...

Understanding the Self01:28

Understanding the Self

407
The self is a central aspect of human identity, encompassing an individual’s beliefs, emotions, perceptions, and experiences. It is a cognitive and psychological construct that enables individuals to interpret their traits and behaviors, influencing how they perceive themselves and interact with the world. While personality consists of stable and enduring characteristics, the self is shaped by self-perception and social experiences. This distinction highlights the dynamic nature of the...

Area of Science:

  • Educational Psychology
  • Motivation Science

Background:

  • Self-Determination Theory (SDT) by Deci and Ryan categorizes motivation regulation.
  • Introjected and identified regulation were previously described as "somewhat external" and "somewhat internal," lacking precise measurement.
  • The theoretical framework of SDT suggests a simplex structure for motivation regulation.

Purpose of the Study:

  • To introduce a constrained regression analysis for optimally estimating "vaguely expressed" motivations within SDT.
  • To generalize this technique for simplex structure analysis in SDT.
  • To empirically test the internalization of motivation in different science teaching formats.

Main Methods:

  • Constrained regression analysis was developed and applied.
  • The method was generalized for simplex structure analysis.
  • An empirical study compared science teaching in classical versus outdoor settings using the Academic Self-Regulation Questionnaire.

Main Results:

  • Science teaching format did not significantly affect the internalization of identified regulation.
  • Introjected regulation internalization shifted towards the external pole in the outdoor teaching format.
  • The quantification approach supported the simplex structure of SDT, contrasting with findings from correlational analyses.

Conclusions:

  • The developed constrained regression analysis provides a method for optimal estimation of motivation internalization.
  • Outdoor science teaching can influence the internalization of specific motivational regulations, specifically introjected regulation.
  • This quantitative approach offers empirical support for the proposed simplex structure within Self-Determination Theory.
