Jacques dodson's law is about the relationship between motivation and work efficiency. This law was first discovered by psychologists Jaecks and dodson through experimental research in 1908.

1, this law describes a curve, the horizontal axis is the work difficulty and the vertical axis is the work efficiency. It shows that with the increase of work difficulty, people's work efficiency will increase first and then decrease. The law further points out that the task with moderate difficulty is the task that can stimulate people's work efficiency most.

The principle of this law can be explained as follows: when the task is moderately difficult, people will find it neither too easy nor too difficult, so it is easier for them to stay focused and devoted, thus improving work efficiency. However, when the task is too difficult or too difficult, people may feel depressed or bored, which will lead to the decrease of their attention and work efficiency.

This law is widely used in education, workplace and daily life. For example, in the field of education, understanding yerkes-dodson Law can help teachers to better design courses and activities to adapt to different students' learning styles and ability levels. In the workplace, this law can guide managers to assign suitable employees according to the difficulty of tasks, thus improving the overall work efficiency.

The origin of Jacques dodson's law

1, dodson's law of Jaecks can be traced back to an experiment of Jaecks and dodson in 1908. The purpose of this experiment is to study the relationship between anxiety and performance, but it is found that with the increase of task difficulty, the anxiety level of subjects will also increase, and the anxiety level has a direct impact on work efficiency.

2.Jaecks and dodson found in the experiment that when the task is difficult, the subjects are easily bored and lack of challenge, which leads to their low work efficiency. When the task is too difficult, the subjects will feel anxious and stressed, which will also affect the work efficiency. On the contrary, moderately difficult tasks can stimulate the motivation and interest of the subjects.

3. After further research and verification, this experimental result finally forms yerkes-dodson law. This law reveals the relationship between motivation and work efficiency, and shows that the task with moderate difficulty is the task that can stimulate people's work efficiency most. The discovery of this law provides important theoretical support for the field of psychology and also provides guidance for many practical application fields.
