Semantic memory as assessed by the Pyramids and Palm Trees Test: the impact of sociodemographic factors in a Spanish-speaking population.
The objective of this study is to obtain preliminary normative data on the performance the Pyramids and Palm Trees Test (PPT) for a Spanish-speaking population. The effects of age, gender, and educational level on the PPT test were also analyzed. A total of 234 healthy participants, with a broad range of age (18-80 years) and education (1-20 years) performed the three-picture version of the PPT. The mean performance was 51.1 out of 52 possible points (SD=1.3). PPT performance did not vary with age or gender. However, subjects with less than 6 years of formal education scored significantly lower than those with more than 6 years of education though this effect was confounded with age because the group with lower education was also older. Given the ceiling effects of the PPT, further investigation is needed to determine if the visual PPT is sensitive to mild semantic memory impairment.
