Turkish children's Bender-Gestalt Test performance: a pilot study and preliminary norms

Area of Science:

• Psychology
• Developmental Psychology
• Neuropsychology

Background:

• The Bender-Gestalt Test is a widely used tool for assessing visual-motor maturity.
• Establishing culturally specific norms is crucial for accurate interpretation of test results.
• Previous cross-cultural studies have indicated variations in performance based on normative samples.

Purpose of the Study:

• To provide preliminary normative data for the Bender-Gestalt Test in a Turkish child population.
• To compare Turkish children's performance with existing international norms, particularly the Koppitz Developmental Scoring System.
• To examine the maturational hypothesis of the Bender-Gestalt Test within a new cultural context.

Main Methods:

• Administered the Bender-Gestalt Test to 253 children in Turkey, aged 5 years 5 months to 11 years 10 months.
• Utilized the Koppitz Developmental Scoring System to calculate mean error scores for different age groups and genders.
• Compared obtained mean error scores with established norms from previous cross-cultural studies.

Main Results:

• Mean error scores were 4.2 (SD = 3.3) for girls and 3.6 (SD = 3.0) for boys.
• Error scores demonstrated a decrease across increasing age groups, supporting the maturational hypothesis.
• Turkish children aged 5 and 6 performed at a higher developmental level than the Koppitz normative sample; other age groups showed similar performance to U.S. norms.

Conclusions:

• The findings support the maturational hypothesis of the Bender-Gestalt Test.
• The study highlights the importance of developing localized norms for visual-spatial tests in different cultural settings.
• Cross-cultural data suggest that performance patterns on the Bender-Gestalt Test can be influenced by cultural and environmental factors.
