Individual differences in social motivation have an influence on many behaviours in both clinical and non-clinical populations. As such, social motivation has been identified as a biological trait that is particularly well-suited for dimensional approaches cutting across neuropsychological conditions. In the present paper, we tested whether social motivation had a similar impact in the general population and in a neuropsychological condition characterized by diminished social motivation: Autism Spectrum Disorders (ASD). More precisely, we evaluated the effect of social motivation on face evaluations in 20 adolescents with ASD and 20 matched controls using avatars parametrically varying in dominance and trustworthiness. In line with previous research, we found in the control group that participants with higher levels of social motivation relied more on perceived trustworthiness when producing likeability judgments. However, this pattern was not found in the ASD group. Social motivation thus appears to have a different effect in ASD and control populations, which raises questions about the relevance of subclinical or non-clinical populations to understand ASD.
个体在社会动机方面的差异会对临床和非临床人群的许多行为产生影响。因此，社会动机已被确定为一种生物特征，非常适合跨神经心理障碍进行维度方法研究。在本文中，我们测试了社会动机是否对一般人群以及以社会动机减弱为特征的神经心理障碍（自闭症谱系障碍，ASD）有类似的影响。更确切地说，我们使用在支配力和可信度方面参数化变化的头像，评估了 20 名 ASD 青少年和 20 名匹配对照组中社会动机对面孔评价的影响。与之前的研究一致，我们在对照组中发现，社会动机水平较高的参与者在进行喜爱度判断时更依赖于感知的可信度。然而，在 ASD 组中并未发现这种模式。因此，社会动机在 ASD 和对照组中的作用似乎不同，这引发了关于亚临床或非临床人群对理解 ASD 的相关性的问题。
