Brain Dominance Test – BDT
Measures individual preferences for left-brain (analytical, logical) versus right-brain (intuitive, holistic) cognitive styles.
Scale Development & Technical Details
Scale Overview
The Brain Dominance Test – BDT was developed by Institut für Psycho-Naturwissenschaften (IPN) (Unknown). It is designed to measure Hemispheric dominance / cognitive style. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 28 items organized into 2 factors/subscales: Left Brain Dominance, Right Brain Dominance.
| Factor / Subscale | Items | N |
|---|---|---|
| Left Brain Dominance | 2,4,5,6,7,10,11,13,20,23,28 | 11 |
| Right Brain Dominance | 1,3,8,9,12,14,15,16,17,18,19,21,22,24,25,26,27 | 17 |
Response Format
Respondents rate each item using a dichotomous Yes/No format.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 0 to 28. Interpretation guidelines:
- Scores are calculated by summing the 'Yes' responses for each subscale to determine relative hemispheric dominance.: 0 – 28
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Not reported.
Administration
The scale is self-administered and typically takes approximately 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
