Description of the Questionnaire

The Asymmetry Questionnaire, developed by Bruce E. Morton, aims to determine cerebral dominance — whether a person functions with a preference toward the right or the left hemisphere of the brain. It consists of pairs of statements representing thought and behavior patterns associated with each hemisphere.

Objective

The objective of the questionnaire is to explore hemisphericity, the tendency of a person to perceive and process the world primarily through right- or left-hemisphere brain functions. This orientation affects one’s cognitive and emotional style.

Data Use

The questionnaire results can be used in psychological assessment, educational guidance, the creation of learning profiles, career development, and research on the relationship between brain processing and behavior.

Data Analysis and Interpretation

The questionnaire contains fifteen pairs of statements. For each pair, the respondent selects the statement that best describes them. Statements in Column A are associated with right-brain characteristics such as emotional sensitivity, creativity, and holistic thinking. Statements in Column B reflect left-brain characteristics, such as logical thinking, analysis, and linear processing. By identifying preferences between each pair, conclusions can be drawn about the individual’s dominant cognitive style.

Scoring

For each pair, the chosen statement is marked. At the end, the total number of selections from Column A and Column B are counted. If most responses fall under Column A, it suggests a preference for right-hemisphere functioning. If most responses are from Column B, it indicates a preference for left-hemisphere functioning. An equal number of selections suggests balanced or mixed hemispheric processing.
