Adult norms for the Rey-Osterrieth Complex Figure Test and for supplemental recognition and matching trials from the...

Area of Science:

• Neuropsychology
• Cognitive Psychology
• Psychometrics

Background:

• The Rey-Osterrieth Complex Figure Test is a widely used measure of visuospatial construction and memory.
• The Extended Complex Figure Test (ECFT) builds upon the Rey by adding Recognition and Matching trials.
• Both tests are valuable tools in assessing cognitive functions.

Purpose of the Study:

• To investigate the impact of age and education on performance on the Rey and ECFT in healthy adults.
• To develop age-appropriate norms for the Rey and ECFT using established scoring methods.
• To provide researchers and clinicians with reliable normative data for interpreting test results.

Main Methods:

• Administered the Rey-Osterrieth Complex Figure Test and the Extended Complex Figure Test to 211 healthy adults.
• Collected demographic data including age, education level, and gender.
• Analyzed performance data for age, education, and gender effects using statistical methods.

Main Results:

• Significant age and education effects were observed across all Rey and ECFT trials.
• Education accounted for a small percentage of variance in copy and memory performance.
• Gender effects were found to be negligible.
• Age-appropriate norms were developed using Osterrieth's 36-point scoring system.

Conclusions:

• Age and education are significant factors influencing performance on the Rey and ECFT.
• The developed age-appropriate norms facilitate more accurate interpretation of test scores in diverse adult populations.
• The ECFT, with its expanded trials, offers a comprehensive assessment of visuospatial abilities and memory.
