Law of Duality in Ecology and Psychology


Hey there! Shreyas here. Today I will be talking about the various
processes that bring about duality and ultimately a balance in the universe. For example, there is the top down approach
and the bottom up approach for problem solving in the field of Computer science and Nanotechnology. The universe acts on mechanistic principles. The Daoists believe in Yin and Yang. So, you can find the duality that exists everywhere. Today, I will be talking about such duality
in the field of Ecology and Psychology. In Ecosystems, you can find two dominant theories. The bottom up approach and the top down approach. In Ecology, for bottom up approach, the nutrient
supply is the main criteria for balancing the ecosystems. If you increase the amount of nutrients, there
will be more number of producers or the green plants. Since there are more number of green plants,
there would be more consumers at different trophic levels similar to a chain reaction. This is how the ecosystem is balanced through
bottom up approach. Coming to the top down approach, many scientists
view that more number of predators try to balance out the ecosystem at the top trophic
level. For example, if there are more number of predators,
there would be few grazers. Since there are few grazers, there would be
more number of producers or green plants. So, you can see these two approaches trying
to balance the ecosystem. Coming to the field of psychology, for studying
perception, you can find similar approach. The bottom up approach states that you get
in all the information through your senses, through your eyes, ears and then you send
it top for higher cognition. You send the information to your brain for
processing. This is the bottom up approach for studying
perception. The top down approach says that you form a
concept in your mind and then you act on it to form a behaviour. For example, you are in a dark room and you
don’t know where the objects are located. Through your past experience, you form a concept
in your mind and then navigate in the dark room. This is the top down approach for studying
perception in Psychology. So, as you can see, the duality exists everywhere. So, to conclude, the earth acts as a self
sustaining system and the law of duality is real and it is not metaphysics. Thank you for watching. Have a great day!
