“…This result was in fact also apparent in Table 1, where the "jaw height" feature (no. 21 in Table 1) was the among the "top 5" positive correlations with youthful-attractiveness (together with the four eye-related features we listed previously), and the other jawline features (22)(23)(24) were all in the "top 11.

“…1 provides an overview of the methods. To quantify first impressions, we used a database of 1,000 highly variable ambient face photographs of adults of overall Caucasian appearance, which had been previously rated for a variety of social traits by observers with a Western cultural background (21)(22)(23)(24). We focused on first impressions of Caucasian-looking faces by participants with a Western upbringing to avoid possible confounding influences of "other-race" effects (25,26).…”

First impressions of social traits, such as trustworthiness or dominance, are reliably perceived in faces, and despite their questionable validity they can have considerable real-world consequences. We sought to uncover the information driving such judgments, using an attribute-based approach. Attributes (physical facial features) were objectively measured from feature positions and colors in a database of highly variable "ambient" face photographs, and then used as input for a neural network to model factor dimensions (approachability, youthful-attractiveness, and dominance) thought to underlie social attributions. A linear model based on this approach was able to account for 58% of the variance in raters' impressions of previously unseen faces, and factor-attribute correlations could be used to rank attributes by their importance to each factor. Reversing this process, neural networks were then used to predict facial attributes and corresponding image properties from specific combinations of factor scores. In this way, the factors driving social trait impressions could be visualized as a series of computer-generated cartoon face-like images, depicting how attributes change along each dimension. This study shows that despite enormous variation in ambient images of faces, a substantial proportion of the variance in first impressions can be accounted for through linear changes in objectively defined features.

“…From ratings of the perceived trustworthiness of these 1,000 face photographs established in previous studies (Santos & Young, 2005;Santos & Young, 2008;Santos & Young, 2011;Sutherland, et al, 2013;Sutherland, et al, 2015) the 15 male faces with lowest rated trustworthiness and the 15 male faces with highest rated trustworthiness were selected, subject to constraints that the photographs included no spectacles, were sufficiently close to frontal view that both eyes were visible, showed no beards or moustaches, and that there were no more than two faces with hats in each set. These constraints were introduced only to allow the creation of relatively sharp averaged images.…”

Impairments of emotion recognition have been widely documented in Huntington's disease (HD), but little is known concerning how these relate to other aspects of social cognition, including first impressions of traits such as trustworthiness and dominance. Here, we introduce a novel and sensitive method to investigate the ability to evaluate trustworthiness and dominance from facial appearance, with control tasks measuring ability to perceive differences between comparable stimuli. We used this new method together with standard tests of face perception to investigate social cognition in HD. We found that a subgroup of people with HD was impaired at perceiving trustworthiness and dominance, and that perceiving trustworthiness and dominance were correlated with impaired facial expression recognition. In addition, we used diffusion tensor imaging (DTI) to provisionally identify candidate brain regions associated with social cognition by contrasting regional functional anisotropy (FA) measures between subgroups of HD participants showing normal or impaired perception of trustworthiness and dominance, and by correlating these regional brain abnormalities with behavioural performance on tests of emotion recognition. In this way we show for the first time alterations in perception of trustworthiness and dominance in people with HD and link these to regions which may map the boundaries of the social brain. The pattern of breakdown seen in this neurodegenerative disease can thus be used to explore potential inter-relationships between different components of social cognition.
