Description

The Brain Dominance Scale (AQ-20) is a tool designed to assess the dominance of brain functions related to left and right brain skills. The AQ-20 includes 20 questions that evaluate the dominance of left and right brain functions, such as logical reasoning, analytical thinking, and creativity.
The questions cover various areas:
Left Brain Function: Focuses on logical reasoning, analytical thinking, and problem-solving abilities.
Right Brain Function: Focuses on creativity, visual thinking, and expressive abilities.
Participants respond to each question using a Likert scale, which measures the degree of agreement or disagreement with the statements.

Data Analysis and Use

The analysis of data from the AQ-20 involves quantitative techniques for assessing the dominance of brain functions:
Descriptive Statistics:Means and Standard Deviations: Calculation of means and standard deviations for each question or for the subscales of the scale.
Reliability: Assessment of the internal consistency of the tool using Cronbach’s alpha to confirm the reliability of the results.
Correlations:Examination of correlations between scores for different questions or subscales to understand the relationships between left and right brain functions.
Factor Analysis:Use of factor analyses to identify key factors affecting brain function dominance, if deemed necessary.

Goal

The primary goal of the AQ-20 is to provide a reliable tool for assessing the dominance of brain functions, contributing to:
Research Purposes: Study the relationship between brain functions and psychological or cognitive factors.
Clinical Assessment: Evaluate individuals’ strengths and weaknesses based on their brain functions.
Educational Use: Understanding brain function dominance to develop teaching and learning strategies.

Calibration

The calibration of the AQ-20 includes:
Assessment of Internal Consistency: Calculation of the tool’s reliability using Cronbach’s alpha to ensure response consistency.
Comparative Analysis: Comparison of AQ-20 results with data from other relevant studies to confirm the validity and reliability of the tool.
