Yoked Control: A Review of the Use of Yoked Control in Behavioral Research
Abstract
Yoked control is an experimental design in which two or more experimental subjects are matched so that their behavior is influenced by the behavior of one another. This design has been used in a variety of research settings, from studies of animal cognition to clinical trials of drug treatments for mental health disorders. The purpose of this review is to examine the research that has been conducted using the yoked control design. We discuss the advantages and disadvantages of this design, as well as the implications of the results. In addition, we provide suggestions for future research using this design.

Introduction
Yoked control is an experimental design in which two or more experimental subjects are matched so that their behavior is influenced by the behavior of one another. This design has been widely used in behavioral research, including studies of animal cognition, clinical trials of drug treatments for mental health disorders, and studies of human learning. The purpose of this review is to examine the research that has been conducted using the yoked control design. We discuss the advantages and disadvantages of this design, as well as the implications of the results. In addition, we provide suggestions for future research using this design.
Advantages of Yoked Control
The yoked control design offers several advantages for behavioral research. First, the design allows for the comparison of two or more experimental subjects, allowing for a more comprehensive understanding of the behavior being studied. Second, the design allows for the control of extraneous factors and the measurement of independent variables. Third, the design allows for the study of inter-individual differences, such as differences in reaction time, motivation, and learning ability. Finally, the design is relatively easy to implement, making it a cost-effective research strategy.
Disadvantages of Yoked Control
The yoked control design also has several potential disadvantages. First, the design can be difficult to implement in some research settings, such as laboratory studies of animal behavior. Second, the design can be limited in its ability to measure the effects of independent variables. Third, the design can be confounded by the presence of confounding variables, such as behavioral differences between the experimental subjects. Finally, the design can be difficult to implement in clinical settings, as it requires careful matching of the experimental subjects.
Implications of the Results
The results of studies using the yoked control design can have important implications for research and practice. For example, the results of studies of animal cognition can inform our understanding of the evolution of cognitive abilities in humans. The results of clinical trials of drug treatments can inform our understanding of the efficacy of the treatments, as well as the potential side effects. Finally, the results of studies of human learning can inform our understanding of educational interventions.
Conclusion
In conclusion, the yoked control design has been used in a variety of research settings, from studies of animal cognition to clinical trials of drug treatments for mental health disorders. The design offers several advantages, including the ability to compare two or more experimental subjects, control extraneous factors, and measure independent variables. However, the design also has several potential disadvantages, including the difficulty of implementation in some research settings and the potential for confounding variables. The results of studies using this design can have important implications for research and practice, and suggest directions for future research.
