摘要本研究的目的是确定命名困难是否出现在50多岁的年轻人身上。25-35岁、50-59岁、60-69岁和70岁以上的参与者被赋予图片命名任务。为了揭示命名的微妙困难，除了准确性之外，还分析了lavelet。为了控制预期的较慢的命名延迟是否可能是由于影响所有认知任务的一般减慢，参与者还被赋予了奇/偶判断任务以评估认知处理速度。结果证实，50多岁的参与者在命名性能方面表现出下降，表现为命名延迟的增加，而60多岁和70多岁的成年人在准确性方面表现出下降，延迟增加。此外，命名延迟的增加仍然显着，即使在控制奇/偶判断延迟后，这表明特定的图片命名任务的退化。我们假设这些较慢的laveling可能是由语言特异性损伤引起的。作为对特定语言退化的进一步测试，参与者的语义能力也通过同义词判断任务和金字塔和棕榈树测试进行了评估。70岁以上组出现语义退化。讨论了多种因素对老年人命名困难的影响。(JINS，2013，19，1-8）
Abstract The aim of this study was to determine whether naming difficulties arise in individuals as young as their 50s. Participants of 25–35, 50–59, 60–69, and above 70 years of age were given a picture naming task. To uncover subtle naming difficulties, latencies were analyzed in addition to accuracy. To control whether the expected slower naming latencies could be due to a general slowing affecting all cognitive tasks, participants were also given an odd/even judgment task to assess cognitive processing speed. The results confirmed that participants in their 50s presented decline in naming performance, reflected by an increase in naming latencies, whereas adults in their 60s and their 70s showed both a decrease in accuracy and an increase in latency. Moreover, the increase in naming latencies remained significant even after controlling for odd/even judgment latencies, suggesting a degradation specific to the picture naming task. We assumed that these slower latencies may result from a language-specific impairment. As a further test for language-specific degradation, participants’ semantic capacities were also assessed with a synonym judgment task and the Pyramids and Palm Trees test. The above-70 group showed semantic degradation. The contributions of multiple factors to naming difficulties in aging are discussed. (JINS, 2013, 19, 1–8)
