青年(男性=20.4岁)和老年(男性=70.7岁)受试者参加了3个视觉半视野实验。这些研究旨在考察大脑半球不对称性的具体方面：(A)语音-语言加工的半球优势(通过识别非单词三联体来测量)，(B)三联体加工策略的半球差异，(C)被认为反映大脑半球唤醒不对称性的特征知觉偏差，以及(D)加工面部情绪的半球优势。左右不对称的模式在年长和年轻的参与者中是相似的，并且两组不对称的各种测量之间的相互关系是相似的。鉴于目前的结果，大脑半球不对称的变化似乎不太可能对与年龄相关的认知功能变化有显著贡献。(心理信息数据库记录(C)2016 APA，保留所有权利)
Younger (M age= 20.4 years) and older (M age= 70.7 years) adults participated in 3 visual half-field experiments. These were designed to examine specific aspects of hemispheric asymmetry:(a) hemispheric dominance for phonetic–linguistic processing (as measured by identification of nonword trigrams),(b) hemispheric differences in trigram processing strategy,(c) characteristic perceptual biases thought to reflect hemispheric arousal asymmetries, and (d) hemispheric dominance for processing emotions shown on faces. Patterns of left–right asymmetries were comparable for older and younger participants, and intercorrelations among the various measures of asymmetry were similar for both groups. In view of the present results, it seems unlikely that changes in hemispheric asymmetry contribute significantly to age-related changes in cognitive functioning.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
