Psychological reflection has initiative, and psychology is a subjective image of the objective world. It does not passively reflect reality like a mirror, but actively, actively and selectively reflects and reacts reality in practical activities.
The human brain is the material organ produced by psychology, and the content of psychology must come from the objective natural environment and people's social life practice. Therefore, psychology is the reflection of objective reality in the human brain.
Objective external things act on people's sensory organs, which turn objective things into images through brain activities, thus producing people's psychology. Objective reality is the source of people's psychological activities. It is impossible for the human brain to produce psychological phenomena without objective reality. The human brain seems to be a "processing factory", and the objective reality is the raw material. The content of people's psychological activities, whether simple or complex, comes from objective things. The images we perceive and represent are copies, photographs and mirror images of objective things in the brain.
Psychological reflection is a dynamic reflection, because through psychological activities, we can not only understand the external phenomena of things, but also realize that social life practice plays a restrictive role in people's psychology. In other words, there is no social life practice, only a sound brain will not produce normal psychological knowledge about the nature of things and the internal relationship between things, and use this knowledge to guide people's practical activities and transform the objective world.
