Although based on the theory and research there is a strong correlation between left brain dominance students to their reading proficiency but the researchers were not to know are those was also having any correlation with their learning style? Then, the researcher was to intensely answer the following; 1. Was there a relationship between students’ learning preferences and reading proficiency and their left-brain dominance? 2. Was there a relationship between a student’s proficiency in reading and their right-brain dominance and learning style? The tools used a questionnaire to know the students brain dominance and learning style was administered to 111 of 3rd university students of Veteran Bangun Nusantara University, Sukoharjo, Indonesia. The students reading proficiency score were documented from the reading 2 teacher. The researcher analyzed the relationship among these variables with simple linear regression (SLR) and multiple linear regression (MLR) through SPSS 16 and interpreting the result. The word findings here become key was a correlation among students left brain dominance, visual learning style and reading proficiency of 24.2%. There was a slightly correlation among left brain dominance, auditory learning style and reading proficiency with 12.1%. There was a slight correlation among left brain dominance, kinesthetic learning style and reading proficiency with 0.2%. There was no correlation among right brain dominance, visual learning style and reading proficiency with 0%. There was only a slight correlation among brain dominance, auditory learning style toward reading proficiency with 2.4%. There was correlation among the right brain, kinesthetic and reading proficiency with 75 %
