One Brain, Two Minds?
Does each of our brains have two minds? Studies carried out by neuropsychologist Roger Sperry in the 1960s revealed that each human brain has two minds which can think differently and independently. The discovery led to him being awarded the Nobel Prize in 1981. This minisite explains the reason why each human brain has two minds.
Human Brain Is Designed To Make Decisions
Making right decisions is the most basic requirement to fulfil the goals of any goal seeking activity. To reach the goals of survival and reproduction (the core goals that drive the process of evolution) the optimizing aspect of the evolutionary process has resulted into humans and other organisms to develop an area in their body - the brain - which enables them to make optimized decisions on their interactions based on their dynamically changing environments and conditions using information processing.
To make such decisions in optimized manner, the human brain processes information related to them in two ways,
- by making logical decisions (direct logic processing) and
- optimizing such decisions by processing them with past data (i.e. information stored on earlier occasions) of the same or similar nature (contextual logic processing).
Such dual approach processes direct logical evaluation of the current interaction with one or more evaluations of same or similar past interactions stored in the database in the form of details, summaries, trends, probability factors, etc. related to them (when required and available), thus providing a better understanding of the interaction, which aids in making optimized decisions.
