[Taylor Complex Figure test: administration and correction according to a normalization and standardization process...

Area of Science:

• Neuropsychology
• Cognitive Psychology
• Psychometrics

Background:

• The Taylor Complex Figure (TCF) is an alternative to the Rey-Osterrieth Complex Figure for assessing visuo-constructive abilities and visual memory.
• Normalization of the TCF for the Spanish population was previously lacking, hindering its widespread clinical application in this demographic.

Purpose of the Study:

• To establish normative data and standardize the administration and scoring of the TCF for the Spanish population.
• To account for sociodemographic factors, specifically age, education level, and gender, in TCF performance.

Main Methods:

• The study involved 700 participants aged 18-90, as part of the Normacog Project.
• Visuo-constructive ability and immediate visual memory were assessed using the TCF.
• Statistical analyses examined the influence of age, education, and gender on TCF performance, yielding percentiles and scalar scores.

Main Results:

• Both age and level of education significantly affected TCF performance in copying and memory tasks; gender did not show a significant effect.
• Age and education collectively explained 25.3% to 35.7% of the variance in TCF performance.
• Poorer performance on the TCF was observed in older and less educated individuals.

Conclusions:

• The study provides administration guidelines, scoring methods, and crucial normative data for the TCF tailored to the Spanish adult population.
• These findings facilitate more accurate neuropsychological assessments of visuo-constructive and memory functions in Spain.
• The developed norms are adjusted for age and educational level, enhancing the TCF's utility in clinical and research settings.
