left vs right

actually it is interesting topic and i have learned something new from the pictures statement.at first,i look the girl spinning clockwise.then i take a time for a while i saw she's spinning anticlockwise.i don't know when and how she changes her turning.it's so confusing me.as we know,based on the Roger Sperry theory,our brain is divided to two parts left and right hemisphere brain.supposedly the result i looking the girl is more spinning clockwise but actually i realized i used more my left brain than right brain.i'm really confused and confused.so,i do my left and right brain quizzes and i got the left brain user result.maybe it's 85% true.for example,i like mathematics and sciences and i don't like literature.but sometimes i have use my right brain like being imagination and subjectives person.i don't know what brain i used.maybe i used both of them.personally,i think we should not suspect to use only one of our brain but we must used both of our brain.we must balanced our positives and negatives thinking,it's very useful to us to get benefit from their functions.as a conclusion,both of side brain is very important.
