There are a variety of well-established neuropsychological tests that are helpful in identifying global and specific verbal memory deficits. In contrast, tests of visual memory have produced less consistent results likely due in part to confounding variables such as verbal encodability, administration difficulties, and insufficient differentiation of among types of visual memory. The Brown Location Test (BLT) was designed to specifically measure visual memory for location of identical objects (dots) and address limitations found in commonly employed visual memory tests. This paper describes the empirical basis for the BLT and reports the psychometric properties of the test. Results indicate good internal and alternate form reliabilities. Factor analysis of a brief test battery confirmed that BLT performance is generally independent of verbal memory and global intellectual abilities. BLT performance declined with age, but there was no association between performance and gender, education, or intellectual functioning. In view of the favorable psychometric properties observed during preliminary studies, additional normative and validation studies in healthy and patient populations are warranted.
有多种成熟的神经心理学测试有助于识别整体和特定的言语记忆缺陷。相比之下，视觉记忆测试的结果则不太一致，这可能部分归因于诸如言语可编码性、施测困难以及视觉记忆类型之间区分不足等混杂变量。布朗位置测试（BLT）旨在专门测量对相同物体（点）位置的视觉记忆，并解决常用视觉记忆测试中发现的局限性。本文描述了BLT的实证基础，并报告了该测试的心理测量特性。结果表明其具有良好的内部信度和复本信度。对一组简短测试电池进行的因素分析证实，BLT的表现通常独立于言语记忆和整体智力能力。BLT的表现随年龄下降，但表现与性别、教育程度或智力功能之间没有关联。鉴于在初步研究中观察到的良好心理测量特性，有必要在健康人群和患者群体中进行更多的常模和验证研究。
