Summary
Household waste sorting knowledge influences environmental concern, but not directly behavior. Environmental concern fully mediates the link between knowledge and waste-sorting behavior in Indonesian households.
Area of Science:
- Environmental Science
- Behavioral Science
- Social Science
Background:
- Waste management is a critical global challenge requiring innovative solutions.
- Understanding household waste sorting behavior is essential for effective waste management strategies.
- The stimulus-organism-response (SOR) model provides a framework for analyzing behavioral influences.
Purpose of the Study:
- To propose and test a conceptual framework based on the SOR model for household waste sorting behavior.
- To investigate the influence of waste sorting knowledge, awareness, and environmental concerns on waste sorting behavior.
- To examine the mediating role of environmental concern in the relationship between knowledge and waste sorting behavior.
Main Methods:
- Structural Equation Modeling (SEM) was used to test the proposed conceptual framework.
- Confirmatory Factor Analysis (CFA) was employed to evaluate measurement validity and reliability.
- Data were collected from 131 households in Banyuwangi, Indonesia, using purposive sampling.
Main Results:
- Knowledge significantly influenced awareness (β=0.679) and environmental concern (β=0.105).
- Environmental concern significantly determined waste-sorting behavior (β=0.883), while awareness did not (β=0.342).
- Knowledge did not directly influence waste-sorting behavior (β=-0.053), but environmental concern fully mediated this relationship.
Conclusions:
- Environmental concern is a key driver of household waste sorting behavior, fully mediating the impact of knowledge.
- Intervention campaigns should focus on enhancing environmental concern to promote waste sorting.
- The SOR model is applicable to understanding waste management behavior in developing countries.

01:28Behaviorism
4.2K
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...

01:06Law of Effect
2.4K
B.F. Skinner, a prominent figure in behavioral psychology, introduced operant conditioning by emphasizing the role of consequences in shaping behavior. This theory builds upon the law of effect proposed by Edward Thorndike, which posits that behaviors followed by satisfying outcomes are likely to be repeated. In contrast, those followed by unsatisfying outcomes are less likely to recur.

02:30Naturalistic Observations

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...

01:05Instinctive Drift
607
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

01:21Behavior Modification
521
Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
