Instructions: The Left Brain vs Right Brain Test (Brain Dominance Questionnaire – BDQ-20) is a self-report questionnaire designed to highlight whether an individual’s thinking style is more left-brained (logical, analytical, structured) or right-brained (creative, intuitive, imaginative). It contains 20 statements, and you need to choose the option that best describes your typical approach or preference. The results provide insight into your cognitive style by comparing left vs right brain dimensions.
Disclaimer: This self-assessment is inspired by research on split-brain theory and hemispheric specialization (e.g., Sperry, 1968; Gazzaniga, 2000). While based on these findings, the test is intended for educational and self-reflection purposes only.

Left Brain vs Right Brain Dimensions

According to brain dominance research, the brain is divided into two halves: the right one is responsible for creativity and emotions, and the left one is responsible for logical and analytical work, but they function together as a whole. In the 1960s and 1970s, neuropsychologists such as Roger W. Sperry and Michael S. Gazzaniga studied “split-brain” patients. They discovered that the left hemisphere is generally more involved in language, logic, and sequential processing, while the right hemisphere is more involved in spatial awareness, nonverbal cues, music, and holistic processing. For this work, Sperry was awarded the 1981 Nobel Prize in Physiology or Medicine. Modern research shows that while the brain is divided into two halves and has specialized functions, both hemispheres work together, and people do not have a “left-brain personality” or “right-brain personality.” Instead, brain dominance may reflect cognitive preferences rather than fixed traits.
