Continuity: the educational methods and environmental influences we received as children ... will have a long-term impact on our future psychology, which is long-term and continuous.
Dynamic: Our psychology and mood will change with the change of environment, weather and season.
Reversibility: for example, we may be in a good mood at first, but then something happened and our mood became very bad, but after a while, our mood gradually improved. This is reversibility.
I hope I can help you.
