Previous studies have investigated the effect of ageing on age estimation from faces as well as the occurrence of an own-age bias in such age estimation from faces. To the best of our knowledge, the occurrence of an own age effect on age estimation from voices has never been examined earlier using an experimental design in which the age of participants (young vs. old) and the age of voice stimuli (young vs. old) were crossed. Results revealed an own-age bias in older adults only. In comparison with younger adults, older participants showed age estimation abilities that are preserved for voices from their own age group and impaired for younger voices. This own age bias was absent in younger participants.
以往的研究调查了衰老对面部年龄估计的影响，以及在这种面部年龄估计中自身年龄偏差的出现情况。据我们所知，此前从未使用一种实验设计来研究自身年龄对声音年龄估计的影响，在该实验设计中，参与者的年龄（年轻与年老）和声音刺激的年龄（年轻与年老）相互交叉。结果显示，只有老年人存在自身年龄偏差。与年轻人相比，老年参与者对来自同一年龄组的声音的年龄估计能力得以保留，而对年轻声音的年龄估计能力则受损。年轻参与者中不存在这种自身年龄偏差。
