NBI Whole Brain Assessment
The Neethling Brain Instrument (NBI) is a scientifically developed tool that helps individuals understand how they think, learn, communicate, and make decisions.
At BrainSmart Assessments, the NBI Whole Brain Assessment forms a central part of our approach to helping learners and adults gain meaningful insight into their cognitive preferences and behavioural tendencies.
Every person processes information differently. The NBI identifies your natural thinking preferences by measuring how you use different parts of the brain when solving problems, studying, planning, or interacting with others.
The Four Thinking Quadrants
Analytical Thinking (L1)
Focuses on logical reasoning, critical thinking, facts, and numerical understanding. Ideal for accuracy, analysis, and structured problem-solving.
Organised Thinking (L2)
Emphasises planning, structure, detail, and step-by-step processes. Excels in organisation, consistency, and attention to detail.
Interpersonal Thinking (R2)
Involves communication, teamwork, empathy, and relationship-building. Thrives in collaborative and people-oriented environments.
Strategic Thinking (R1)
Encourages creativity, innovation, big-picture thinking, and future planning. Excels in creative problem-solving and generating new ideas.
The goal is not to label people, but to help them recognise and leverage their natural strengths while developing other areas.
