This baseline study aimed to create a coherent set of images that can be used to describe language decline found in healthy elderly and to compare this to the language change found in the early stages of Alzheimer's disease. To this extend, a typed picture naming task was created, in which visual complexity, age-of-acquisition, frequency and name agreement were controlled for. 76 healthy elderly participated in the test; their data will be used in follow-up studies to compare with cognitively impaired patients. The entire typing process was logged with keystroke logging tools Inputlog and Scriptlog; the obtained results were analysed in light of the typing product (name agreement and object recognition) and the writing process (naming latencies and interkey latencies). Results showed that the latencies increased with age and that the older participants had longer latencies for images with a lower frequency and higher age-of-acquisition. Hence, our results indicate the need to take both the latencies and the typing product into consideration.
这项基线研究旨在创建一组连贯的图像，用于描述健康老年人中发现的语言衰退情况，并将其与阿尔茨海默病早期发现的语言变化进行比较。为此，创建了一个打字图片命名任务，其中控制了视觉复杂性、习得年龄、频率和名称一致性。76名健康老年人参与了测试；他们的数据将用于后续研究，以与认知受损患者进行比较。整个打字过程使用按键记录工具Inputlog和Scriptlog进行记录；根据打字结果（名称一致性和物体识别）和书写过程（命名潜伏期和按键间隔时间）对获得的结果进行分析。结果表明，潜伏期随年龄增长而增加，年龄较大的参与者对频率较低和习得年龄较高的图像有更长的潜伏期。因此，我们的结果表明需要同时考虑潜伏期和打字结果。
