Recently, Thibault and colleagues described the Duchenne marker as a cultural dialect for the perception of smile authenticity. The current study had the goal to follow up on this finding and to investigate the cues that French Canadian children use to evaluate the authenticity of smiles from members of three ethnic groups. The authenticity of six smiles differing in intensity and presence of orbicularis oculi (Duchenne marker) was rated by 1206 children from 4 to 17 years of age. No differences were found as a function of encoder group. All children perceived medium Duchenne smiles as more authentic than equally intense medium non-Duchenne smiles. Furthermore, results suggest a decrease in the reliance on intensity across the age span. Younger children use the intensity marker along the whole continuum to infer authenticity. In contrast, older children (14- to 17-year-olds) rated all smiles that did not contain the Duchenne marker as roughly equally low in authenticity.
最近，蒂博ault及其同事将杜兴标志描述为一种用于感知微笑真实性的文化方言。本研究旨在跟进这一发现，并调查法裔加拿大儿童用于评估来自三个种族群体成员微笑真实性的线索。1206名4至17岁的儿童对六种强度不同且存在眼轮匝肌（杜兴标志）的微笑的真实性进行了评分。未发现编码组之间存在差异。所有儿童都认为中等强度的杜兴微笑比强度相同的中等强度非杜兴微笑更真实。此外，结果表明随着年龄增长，对强度的依赖程度有所下降。年幼的儿童在整个连续统一体上使用强度标志来推断真实性。相比之下，年龄较大的儿童（14至17岁）将所有不包含杜兴标志的微笑的真实性评为大致同样低。
