1. Which of the two strategies (i.e. frequency matching or maximizing) will people with normal corpus callosum use? Does this depend on their personal habit? Or do they use these two guessing strategies together?
(1) It may be related to personal interest and preference. Some people may just be satisfied with the maximizing strategy. It may also be related to individual’s physical condition. For example, when one is tired or he or she is just lazy to guess, maximizing strategy is more likely to be used.
(2) It may depend on the dominant hemisphere. If an individual is right brain dominant person, he/she may use maximizing strategy more often. If an individual is left brain dominant person, he or she may be more analytic and use frequency matching more.

For normal person, why we will use frequency matching?
(the answers of Q2 and Q3 are combined as they are similar)
(1) Normal people may use frequency matching more.
(2) Reasons:
1) From evolution perspective, it is of great survival value for human to make some prediction and draw some causal relationship, for example, the right time to sow seeds. Making prediction and attempting to get rid of uncertainty may lead to better adaptation. Thus, human natures let people have the tendency to find patterns and make prediction. This is also the possible reason why children like asking ‘why’ and ‘how’ questions.
2) Left hemisphere tends to interpret and explain things. People are prone to find patterns so that the left hemisphere can explain and interpret the event.
3) From human nature, people always want to get the best outcome. Thus, people use frequency matching and predict the outcome in order to improve the guessing accuracy.
4. Why LH has a tendency to rationalize and interpret incidents. If one’s LH is damaged, can he explain or understand his behavior?
If the person’s language system is located in LH, he or she may not be able to explain and understand the behavior after the language area in LH is
