Standardization and normative data for a new test of visual long-term recognition memory.

The assessment of recognition memory is useful in several neurological conditions, but normative data for visual recognition memory of complex figures are still missing for the Italian population. The aim of this study is to present a new short test of visual recognition memory that consists in a supplementary task to be administered after the free delayed recall trial of the Modified Taylor Complex Figure (MTCF). The MTCF-Recognition Trial (MTCF-RT) includes 10 tables, each with a sub-component of the MTCF coupled with two interfering stimuli. Participants are asked to point, for each triplet, the item that was part of the original picture. Normative data were collected from a sample of 280 healthy Italian native speakers ranging in age from 18 to 89 years. The mean recognition score on the MTCF-RT was 9.125 ± 0.996. Results from multiple regression analyses showed that age and education (but not gender) were significant predictors of performance. Therefore, we provided correction grids to adjust raw scores for age and education and computed equivalent scores for the use of the MTCF-RT in the clinical assessment of recognition memory.
