Rey's Complex Figure Test (Correction)

Memory Phase and Scoring Criteria

After completion of the copying, a short pause is taken, not to exceed three minutes, after which the patient is asked to reproduce the figure from memory.

This second phase evaluates immediate visual memory and the ability to retrieve the previously analyzed information.

For correction, the figure is broken down into 18 specific elements or units (such as the cross, the central rectangle, the diagonals, etc.).

The scoring system assigns values according to accuracy and location: 2 points if the element is correct and well located; 1 point if it is deformed but well located or if it is correct but poorly located; 0.5 points if it is deformed and poorly located; and 0 points if it is unrecognizable or absent.

Interpretation of Results and Scores

The maximum possible score is 36 points. Once the direct score is obtained in both the copying and memory phases, it is compared with the scales corresponding to the age of the subject to obtain the percentile and the diagnostic range.

A percentile below the expected (generally below the 60th or 75th percentile according to clinical criteria) is considered to be a significant indicator requiring further neuropsychological inquiry.

Notable discrepancies between copying and memory may suggest specific failures in information storage or retrieval, beyond perceptual abilities.

Summary

After a maximum pause of three minutes, the memory phase is performed. To correct, the figure is broken down into eighteen specific elements, assigning scores according to the accuracy of the drawing and its spatial location.

The system awards two points for correct and well-placed elements, reducing the score for deformations. Zero points are assigned if the element is unrecognizable or totally absent in the patient's reproduction.

The final score is compared with age-based scales to obtain percentiles. Significant discrepancies between copy and memory suggest specific failures in storage or retrieval, beyond perceptual ability.
