Oral expression becomes worse with ageMay. 18,2015
People’s language ability is changing with age. In their old age, people can maintain and even improve their ability to understand language, but the ability of language expression will have a trend of decline, namely the aging of speech production.
It is generally believed that the decline of anti-interference ability is the main cause of expression aging. Anti-interference ability will limit irrelevant information into the words of language and reduce the influence of irrelevant information on the language expression. If anti-interference ability is damaged, irrelevant information will be activated and extracted, then, people’s language processing will be affected. Recent studies have found that, under different tasks, anti-interference ability of the elderly is worse than that of the young. The decline of anti-interference ability is influenced by the activation level of potential interference.
The research outcomes were published on the third issue of Acta Psychologica Sinica, 2015 and finished by Chen Xuqian and Zhang Jijia respectively from Center for Psychological Application, South China Normal University and Department of Psychology, Renmin University of China.
At present, many research results are not unified. Even in this study, people’s anti-interference abilities are altered in different language content. Therefore, it is necessary to deeply explore the nature of speech production aging to provide guidance for the ability and diagnosis test of the elderly.
