What is a face worth? Facial attractiveness biases experience-based monetary decision-making

The impact of partially covered faces on trust attribution, sharing resources, and perceived fairness of one's own choices in Ultimatum Game

Covered faces have been linked with impaired emotion recognition; yet, it is entirely unexplored how an occlusion due to face masks may affect individuals' behaviour in economic decisions. Across two studies, we explored whether partially covered faces (due to mask wearing or a horizontal black bar) and emotion displayed by the responder influence peoples' sharing behaviour in the Ultimatum Game and the perceived fairness of one's proposal.Study 1 showed participants were more willing to equally share their resources with a happy face (compared to a neutral one). In addition, they were more willing to make a fair proposal when the person displayed was not wearing a face mask. Our results also provide evidence that, when people had to judge how fair their proposal was, participants rated a fair proposal as fairer when responders showed happy faces without masks, while unfair proposals were rated as fairer with happy masked faces; similarly, angry faces led to fairer ratings for fair offers without masks and unfair offers with masks. Study 2 partially confirmed previous results, highlighting how a simple occlusion on the face does not have a direct effect on the proposal but moderates the effect of the displayed emotions.These findings indicate that social interactions might be affected by face occlusion, especially when it is represented by a face mask. Indeed, people might judge the same behaviour in different ways based on the fact that their counterpart has a partially covered face.

Facial attractiveness does not modify the perceived trustworthiness of ethnic minority men

Immigrants, and particularly immigrant men, are often stereotyped as untrustworthy in European societies. However, little research has examined how stereotypes of characteristics other than ethnicity might impact natives' perceptions of the trustworthiness of immigrants. Here, I test whether facial attractiveness, a trait associated with a variety of positive stereotypes, might modify ethnic biases in trustworthiness perceptions. I vary facial attractiveness and ethnicity using photo and name stimuli presented in a hypothetical "lost wallet" vignette, in which respondents assess the likelihood of the pictured man returning their lost wallet. Results from an German online panel survey indicate that while attractiveness has a modest positive effect on perceived trustworthiness, the value of attractiveness does not differ between ethnic majority German men and men with a Turkish migration background. Rather, the largest differences in the perceived trustworthiness of Turkish-origin men are found between respondents with inclusionary and exclusionary immigration attitudes, with inclusionary respondents reporting that Turkish-origin vignette persons are more trustworthy than ethnic majority German vignette persons. These results suggest that physical attractiveness does not act as a substantial moderator of ethnic biases in trustworthiness perceptions, but that immigration attitudes are highly relevant.

Facial attractiveness in the eyes of men with high arousal

INTRODUCTION

Individuals differ in how they judge facial attractiveness. However, little is known about the role of arousal level and gender differences in individuals' facial attractiveness judgments.

METHODS

We used resting-state electroencephalogram (EEG) to investigate this issue. A total of 48 men (aged 22.5 ± 3.03 years [mean ± SD], range: 18-30 years) and 27 women (aged 20.3 ± 2.03 years [mean ± SD], range: 18-25 years) participated in the experiment. After the EEG was collected, participants were instructed to complete a facial attractiveness judgment task. Connectome-based predictive modeling was used to predict individual judgment of facial attractiveness.

RESULTS

Men with high arousal judged female faces as more attractive (M = 3.85, SE = 0.81) than did men with low arousal (M = 3.33, SE = 0.81) and women (M = 3.24, SE = 1.02). Functional connectivity of the alpha band predicted judgment of female facial attractiveness in men but not in women. After controlling for the age and variability, the prediction effect was still significant.

CONCLUSION

Our results provide neural evidence for the enhancement of the judgment of facial attractiveness in men with high arousal levels, which supports the hypothesis that individuals' spontaneous arousal contributes to variations in facial attractiveness preferences.

The effect of attire attractiveness on students' perception of their teachers

Introduction

Generally, people do judge a book by its cover. The purpose of this research is to investigate the effect of teachers' attire on students' perception of 34 psychological dimensions.

Methods

The research is an experiment, with self-reported data, in groups, based on a questionnaire. The participants were 173 students (M_age = 12.16, SD = 1.74) from Suceava, Romania. Two groups of students were asked to listen to a sample lesson of a therapeutic story, narrated by a teacher. One group was given a picture of the attractive teacher and the other group a picture of the unattractive teacher, and were told that the teacher who is narrating is the teacher in the picture. After listening to the same story, the respondents had to answer a questionnaire about teachers' personality and characteristics.

Results

The results indicated that when the teacher is perceived as being more attractive, the students have a greater openness for school activities, the evaluation of the teacher's personality is more positive, the evaluation of the teaching effort is more positive, students expect a higher grade, and the perceived age of the teacher is lower.

Discussion

The article underlines the role of clothing in molding student's perception and raises questions about dress codes in schools. Implications for school context are discussed.

Face Mask Reduces the Effect of Proposer's (Un)Trustworthiness on Intertemporal and Risky Choices

Previous literature suggested that individuals increase temporal and risk discounting at the presence of a proposer whose face is perceived as untrustworthy, suggesting the activation of protective choice patterns. By the way, the COVID-19 pandemic has substantially transformed the way we interact with other people, even bringing us into situations where the face of the person making a proposal is not fully visible, because of the mask. With the current study, we aimed at verifying if the effect of proposer's facial (un)trustworthiness on discounting behavior is modulated by mask wearing. In two different experiments, participants performed traditional delay and probability discounting tasks with masked proposers manipulated across trustworthiness levels. Results highlighted that, even after checking for subject-specific emotion recognition ability with masked faces, the presence of a masked untrustworthy proposer increases both delay and probability discounting parameters, although the effect is not statistically significant and smaller than the one detected at the presence of an untrustworthy proposer without a mask. These results suggest that the ability to perceive the proposer's (un)trustworthiness is affected by the mask, with a consequent less strong effect of proposer's (un)trustworthiness on choice behavior on both intertemporal and risky choices. Limits and possible implications are outlined and discussed.

Gender Biases in the Accuracy of Facial Judgments: Facial Attractiveness and Perceived Socioeconomic Status

Many studies demonstrate that people form their first impression of a stranger based on facial appearance, and these impressions influence their subsequent decisions and behaviors. However, much less research has examined the factors that moderate the accuracy of first impressions based on a photo of face. The present study included three experiments to explore gender differences in the accuracy of impressions based on faces. The results showed that people judge facial attractiveness more accurately for female faces than for male faces while giving more accurate wealth judgments for male faces than for female faces. Interestingly, although we did not find a significant correlation between confidence ratings and the accuracy of wealth rating, we recognized a significant moderate correlation between confidence ratings and the accuracy of attractiveness ratings when female participants rated male faces. To our knowledge, the present study is the first to reveal gender biases in the accuracy of impression judgments based on facial appearance. These findings imply a significant influence of traditional gender roles on accurate facial judgments.

Vocal Attractiveness Matters: Social Preferences in Cooperative Behavior

Research has shown the phenomenon that "what sounds beautiful is good" is a stereotype. It is not clear whether vocal attractiveness affects social decision-making in economic games. Using a modified trust game task, we investigated the neural mechanism of the influence of vocal attractiveness on cooperative decision-making. Participants first heard the voice (attractive or unattractive) of the partner. They had enough time to decide whether to cooperate with the partner for a chance to earn monetary rewards. The behavioral results showed that participants made more invest choices in the attractive partner condition, and they were more likely to cooperate with the female partners in the unattractive voice condition. The event-related potential (ERP) analysis for voice stimuli showed that attractive voices induced larger N1 amplitude than unattractive voices only in the male voice condition. And female voices elicited smaller N1 and larger P2 amplitudes than male voices in both the attractive and unattractive voices condition. A larger P3 amplitude was evoked by female voices and attractive voices. In addition, a more positive late positive complex (LPC) was induced by male voices and attractive voices. This study suggested that attractive voices facilitated cooperative behavior, providing evidence for the "beauty premium" effect of the attractive voices. Moreover, participants were more likely to cooperate with female partners. In the early stage, gender information and male vocal attractiveness were processed automatically, suggesting that male vocal attractiveness was processed preferentially than the female voice. In the late stage, participants allocated attention to both male and female vocal attractiveness.
