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.
本研究的目的是获取针对说西班牙语人群的金字塔和棕榈树测试（PPT）表现的初步规范数据。同时还分析了年龄、性别和教育水平对PPT测试的影响。共有234名健康参与者，年龄范围广泛（18 - 80岁），教育程度也各不相同（1 - 20年），他们进行了PPT的三图版本测试。平均成绩为52分满分中的51.1分（标准差 = 1.3）。PPT表现不因年龄或性别而有所不同。然而，接受正规教育少于6年的受试者得分显著低于接受正规教育超过6年的受试者，不过这种影响因年龄因素而变得复杂，因为受教育程度较低的群体年龄也较大。鉴于PPT存在天花板效应，需要进一步研究以确定视觉PPT对轻度语义记忆损害是否敏感。
