How the Scales are Structured

example score

31/50

Total Score (TS)

This scale measures the balance between left-hemisphere (logical, analytical) and right-hemisphere (imaginative, intuitive) processing styles based on total points scored.

Left-leaning

Balanced

Right-leaning

0 – 15: Left-leaning | 16 – 34: Balanced | 35 – 50: Right-leaning

A score of 31 falls in the Balanced range, suggesting relatively even use of analytical and intuitive approaches with flexibility across different tasks.

CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

What does this assessment measure?

It estimates which hemisphere shows stronger dominance in everyday information processing. Results reflect a tendency toward logical, sequential analysis or intuitive, image-based processing.

What tasks are included?

It uses brief, structured items that compare preferences for details, sequences, images, and emotional cues. Items are simple and require no special knowledge.

How long does it take and how many items are there?

Estimated completion time is about 5 minutes. The assessment includes 25 items.

How should responses be completed for accurate results?

Answer all items based on typical behavior rather than current mood or recent events. Select one option per item and avoid overthinking.

How should results be interpreted and used?

Results indicate relative strengths and common processing habits, not ability or intelligence. They may inform study strategies, communication approaches, and personal development goals.

About This Assessment

Determining the Dominant Hemisphere of the Brain Test

Brain Hemisphere Dominance Assessment Test - Symptoms and Signs

laterality

This brief self-report tool is designed to screen for preferred cognitive style commonly described as left- versus right-hemisphere dominance. Brain Hemisphere Dominance Assessment is intended to provide a rough indication of whether an individual tends to rely more on analytic, sequential processing or more on holistic, intuitive processing in everyday tasks.

The measure consists of 25 items and typically takes about 5 minutes to complete. It is attributed to Roger W. Sperry and Michael S. Gazzaniga.

Results from the Brain Hemisphere Dominance Assessment should be interpreted cautiously and used as a descriptive aid rather than a diagnostic indicator of neurologic function. When used in educational, coaching, or counseling contexts, findings are best integrated with relevant history, observed functioning, and other assessment information.
