Colorfulness influences perceptions of valence and arousal.

Research on color-emotion associations provides evidence that hue, chroma, and lightness relate to various emotional experiences. Most of this research has assessed these relationships via isolated color swatches while confounding color dimensions. We broadened the medium in which color-emotion associations were made by manipulating color in photographs varying in valence and/or arousal, and we solely focused on the chroma dimension. In Experiment 1, participants perceived neutral and positive-valence photographs to be happier and more arousing when displayed chromatically, relative to achromatically. In Experiment 2, participants increased the chroma content of photographs to make them appear maximally happy, and they decreased the chroma content of photographs to make them appear maximally sad. In Experiment 3, participants altered the chroma content of photographs to their preferred levels, with positive-valence photographs containing the most chroma, followed by neutral, then negative-valence photographs. In Experiment 4, participants increased the chroma content of photographs to make them appear maximally positive or arousing, and they decreased chroma to make photographs appear maximally negative or calming. This pattern was similar regardless of the initial valence/arousal content of the images. These results indicate that chroma may convey emotion-relevant information independent of hue or lightness.

Trait- and State-Fear of Missing Out: Influences on Alcohol Craving and Drinking Likelihood.

OBJECTIVE: A growing body of research implicates Fear of Missing Out (FoMO) as a risk factor for collegiate alcohol use. However, little research has explored the causal mechanisms of this association, which may depend on examining FoMO at both trait and state levels. We therefore examined how predispositions toward experiencing FoMO (i.e., trait-FoMO) interacted with state-level cues indicating that one was "missing out" (i.e., state-FoMO) and cues indicating the presence or absence of alcohol. METHOD: College students (n = 544) participating in an online experiment completed a measure of trait-FoMO and were then randomly assigned to one of four guided-imagery script conditions (FoMO/Alcohol cue, FoMO/No Alcohol cue, No FoMO/Alcohol cue, No FoMO/No Alcohol cue). Participants then completed measures of alcohol craving and drinking likelihood for the given scenario. RESULTS: Two hierarchical regressions (one per dependent variable) revealed significant two-way interactions. Greater trait-FoMO demonstrated the strongest, positive associations with alcohol craving following scenarios with FoMO cues present. Reported drinking likelihood was strongest when state-level cues for FoMO and alcohol were both present, moderate when either cue was independently present, and lowest when both cues were absent. CONCLUSIONS: FoMO's impact on alcohol craving and drinking likelihood varied across trait/state levels. Although trait-FoMO was associated with alcohol craving, state-level cues indicating "missing out" affected both alcohol-related variables and interacted with alcohol cues in imagery scenarios to predict drinking likelihood. Although additional research is needed, targeting psychological variables related to meaningful social connection may reduce collegiate alcohol use with respect to FoMO.

The Roles of Gender and Employment Status in Abdication Decisions.

Abdication-the act of giving up a choice to another person-has been shown to prompt reciprocal generosity (Kardas et al., 2018), but it is not clear whether men or women are more likely to engage in abdication. The present research utilized a gift card scenario adapted from Kardas et al. (2018) in two Amazon Mechanical Turk samples to explore whether women abdicated more frequently than men, whether men abdicated to women less frequently than to other men, and whether employment status predicts abdication. In experiment one, participants (N = 520) were assigned to one of three conditions in which they had to either choose who received a hypothetical gift card themselves or abdicate the decision to a friend (sex not specified, male friend, or female friend). Chi-square analyses revealed no significant differences between participants who abdicated and those who allocated; men and women had similar abdication patterns; there was no significant difference in abdication as a function of friend gender for male or female participants. In experiment two, participants (N = 707) were again assigned to one of the three conditions but were also asked their employment status. Chi-square analyses indicated that participants generally preferred to be allocators rather than abdicators; women showed a similar abdication pattern to men; there was no significant difference in abdication as a function of friend gender for male or female participants. Lastly, unemployed participants abdicated more frequently (70%) than their employed counterparts (42%), and this was especially likely for women. These results have implications for potential factors that influence abdication decisions.

The role of facial coloration in emotion disambiguation.

Previous research has demonstrated that some pairs of emotion expressions are confusing to observers because they share common facial-muscular expressive features. Recent research has suggested that another expressive feature, facial coloration, can facilitate the disambiguation of these emotion expressions. The current work tests this hypothesis by presenting participants with pairs of ambiguous emotion expressions with varying facial coloration, then assessing perceived emotion via continuous ratings and categorizations. The results demonstrated that facial coloration can influence perceived emotion within the emotion pairs of anger-disgust (Experiment 1), surprise-fear (Experiments 2a and 2b), and tearful sadness-happiness (Experiment 3). Further, this influence contributed to emotion disambiguation nonuniformly between emotion pairs. Implications discussed include the role of facial coloration in emotion perception, conceptualizations of emotion categories, and the use of posed facial expression stimuli in emotion research.

Facial coloration influences social approach-avoidance through social perception.

Perceptions of others' social characteristics are essential for guiding social behaviour and decision making. Recent research has demonstrated that increased facial redness facilitates both positive (e.g. health, attractiveness, happiness) and negative (e.g. dominance, anger) social evaluations. Given that similar facial colouration can lead to diverging evaluations, it is unclear how people integrate these cues to inform social decisions (e.g. approach-avoidance). We suggest that the influence of facial redness on social perceptions and decisions depends on contextual information, including facial-muscular emotion expressions. We test this hypothesis across two studies where participants view faces either increasing or decreasing redness, evaluate them on a range of social characteristics (i.e. aggressiveness, attractiveness, health, friendliness, dominance) and decide whether to approach or avoid them. Increased facial redness facilitated, and decreased redness impeded (to a greater extent), perceptions of each social characteristic. However, the extent of this influence was moderated by the muscular expression (i.e. neutral, happy, angry). Further, we found that the influence of facial redness on approach-avoidance was largely mediated by evaluations of attractiveness and health. Altogether, the current work provides nuanced insights into facial colouration's role as a social signal that informs social perception and decision making.

Attitudes and behaviour toward snakes on the part of Igbo people in southeastern Nigeria.

Snakes play a crucial role in natural ecosystems, providing ecological services to people by decreasing rodent populations which may cause disease transmission and impair agricultural production. Despite these benefits, snakes are historically a target of persecution and negative attitudes across cultures, and many of them are threatened. Understanding the predictors of snake-human conflicts is essential to improve conservation efforts. We investigated the degree to which emotions, myth beliefs, experience with snakes (via exposure, bites, and knowledge of mortality from a snakebite), and education would predict attitudes toward snakes in a sample of southeastern Nigerian people. We further examined whether attitudes would predict intentional killing of snakes. Ordinal regression analyses revealed that fear, disgust, and belief in the myth that snakes are evil were related to low tolerance of snakes. More frequent encounters with snakes and higher education were associated with higher tolerance of snakes. Furthermore, higher tolerance of snakes was associated with a reduced likelihood of intentionally killing snakes, even when controlling for the influence of the other psychological and experiential variables. Wildlife management education interventions may be important to change attitudes and decrease intentional killing of snakes.

Individual differences in preference for risky behaviors during courtship.

Engaging in risky behaviors is a sexual signalling strategy that men use to procure mates. The present study investigates men's preferences for engaging in risky behaviors (along with women's preferences for their male partner's risky behavior) within dating couples. We investigated associations between relationship length, self-perceived attractiveness, sociosexuality orientation, and preference for risky behaviors in a sample of 256 couples. Results indicated that men had stronger preferences for risky behaviors than their partner's ideal preference. Furthermore, relationship length was associated with a decline in women's preference for their partner's risk-taking, but not men's preference for their own risk-taking. Self-perceived attractiveness was negatively associated with risk preference, and sociosexuality orientation was not directly related to risk preference. Female preferences for less intense male risky behaviors could reflect the need of paternal investment which is required for offspring care. Decreased male sexual signalling could account for lower preferences of risky behaviors in females who are involved in longer lasting romantic relationships.

Social Perception of Facial Color Appearance for Human Trichromatic Versus Dichromatic Color Vision.

Typical human color vision is trichromatic, on the basis that we have three distinct classes of photoreceptors. A recent evolutionary account posits that trichromacy facilitates detecting subtle skin color changes to better distinguish important social states related to proceptivity, health, and emotion in others. Across two experiments, we manipulated the facial color appearance of images consistent with a skin blood perfusion response and asked participants to evaluate the perceived attractiveness, health, and anger of the face (trichromatic condition). We additionally simulated what these faces would look like for three dichromatic conditions (protanopia, deuteranopia, tritanopia). The results demonstrated that flushed (relative to baseline) faces were perceived as more attractive, healthy, and angry in the trichromatic and tritanopia conditions, but not in the protanopia and deuteranopia conditions. The results provide empirical support for the social perception account of trichromatic color vision evolution and lead to systematic predictions of social perception based on ecological social perception theory.

Facial blushing influences perceived embarrassment and related social functional evaluations.

Facial blushing involves a reddening of the face elicited in situations involving unwanted social attention. Such situations include being caught committing a social transgression, which is typically considered embarrassing. While recent research has demonstrated that facial redness can influence social evaluations, including emotional states such as perceived anger, the influence of blushing on social perceptions related to embarrassment or social transgression has yet to be investigated. Across three experiments, we manipulated the redness of neutral faces (Exp. 1) and faces displaying different emotional expressions (Exps. 2 and 3), and had participants evaluate perceived embarrassment, apology sincerity, and likeliness to forgive a transgression for each set of stimuli. Results indicated that redder (relative to baseline) faces influenced perceived embarrassment, apology sincerity, and likeliness to forgive a transgression. We discuss the implications in the context of a social functional account of facial colour in emotion expression and perception.

Face color facilitates the disambiguation of confusing emotion expressions: Toward a social functional account of face color in emotion communication.

Facial expressions of emotion include both muscular and color modulations that contribute to the accurate perception of emotion. However, some emotion categories share common facial-muscular features during the dynamic expressive sequence, which can lead to confusion and misidentification. The current research posits that a potential social function of facial-color expression lies in its ability to disambiguate confusing facial-muscular emotion expressions. In Experiment 1, participants were asked to rate and categorize confusing emotion expressions (i.e., mixed anger-disgust) that varied in facial color (i.e., CIELAB a*, red-green axis). The results showed that changes in facial color facilitated the disambiguation of the confusing emotion expressions for both ratings and categorizations. In Experiment 2, participants were asked to change the color on faces with either disgust, confusing, or anger expressions, to match the emotion being expressed. The results showed that participants differentially used color information to make the faces maximally expressive. Additionally, participants in Experiment 2 consistently applied facial color changes regardless of disambiguating information provided by either explicit instructions or validated expressions. The findings from the current research support a social functional account of facial color in the communication of emotion; facial color makes a unique contribution to emotion expression, independent of facial musculature.

Facial redness, expression, and masculinity influence perceptions of anger and health.

Past research has found that skin colouration, particularly facial redness, influences the perceived health and emotional state of target individuals. In the current work, we explore several extensions of this past research. In Experiment 1, we manipulated facial redness incrementally on neutral and angry faces and had participants rate each face for anger and health. Different red effects emerged, as perceived anger increased in a linear manner as facial redness increased. Health ratings instead showed a curvilinear trend, as both extreme paleness and redness were rated as less healthy than moderate levels of red. Experiment 2 replicated and extended these findings by manipulating the masculinity of both angry and neutral faces that varied in redness. The results found the effect of red on perceived anger and health was moderated by masculine face structure. Collectively, these results show that facial redness has context dependent effects that vary based on facial expression, appearance, and differentially impact ratings of emotional states and health.

Emotion-color associations in the context of the face.

Facial expressions of emotion contain important information that is perceived and used by observers to understand others' emotional state. While there has been considerable research into perceptions of facial musculature and emotion, less work has been conducted to understand perceptions of facial coloration and emotion. The current research examined emotion-color associations in the context of the face. Across 4 experiments, participants were asked to manipulate the color of face, or shape, stimuli along 2 color axes (i.e., red-green, yellow-blue) for 6 target emotions (i.e., anger, disgust, fear, happiness, sadness, surprise). The results yielded a pattern that is consistent with physiological and psychological models of emotion. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Facial Redness Increases Men's Perceived Healthiness and Attractiveness.

Past research has shown that peripheral and facial redness influences perceptions of attractiveness for men viewing women. The current research investigated whether a parallel effect is present when women rate men with varying facial redness. In four experiments, women judged the attractiveness of men's faces, which were presented with varying degrees of redness. We also examined perceived healthiness and other candidate variables as mediators of the red-attractiveness effect. The results show that facial redness positively influences ratings of men's attractiveness. Additionally, perceived healthiness was documented as a mediator of this effect, independent of other potential mediator variables. The current research emphasizes facial coloration as an important feature of social judgments.

Women's Facial Redness Increases Their Perceived Attractiveness: Mediation Through Perceived Healthiness.

In the present research, we investigated whether the red-attraction relation that has been observed for men viewing women may also be observed with regard to women's facial redness. We manipulated facial redness by slightly increasing or decreasing the redness on the faces of baseline pictures of target women, and then had men judge the attractiveness of the women. We also examined healthiness perceptions as a mediator of the redness-attraction relation, along with several other candidate mediator variables. A series of experiments showed that increased redness led to increased ratings of attractiveness, and decreased redness led to decreased ratings of attractiveness. Perceived healthiness was documented as a mediator of the influence of female facial redness on male perceptions of attractiveness, and this mediation was independent of other candidate mediator variables. The findings highlight the importance of attending to facial coloration as an attraction-relevant cue and point to interesting areas for subsequent research.

Red and romantic rivalry: viewing another woman in red increases perceptions of sexual receptivity, derogation, and intentions to mate-guard.

Research has shown that men perceive women wearing red, relative to other colors, as more attractive and more sexually receptive; women's perceptions of other women wearing red have scarcely been investigated. We hypothesized that women would also interpret female red as a sexual receptivity cue, and that this perception would be accompanied by rival derogation and intentions to mate-guard. Experiment 1 demonstrated that women perceive another woman in a red, relative to white, dress as sexually receptive. Experiment 2 demonstrated that women are more likely to derogate the sexual fidelity of a woman in red, relative to white. Experiment 3 revealed that women are more likely to intend to guard their romantic partner from a woman wearing a red, relative to a green, shirt. These results suggest that some color signals are interpreted similarly across sex, albeit with associated reactions that are sex-specific.

Dressed for sex: red as a female sexual signal in humans.

BACKGROUND: In many non-human primate species, a display of red by a female serves as a sexual signal to attract male conspecifics. Red is associated with sex and romance in humans, and women convey their sexual interest to men through a variety of verbal, postural, and behavioral means. In the present research, we investigate whether female red ornamentation in non-human primates has a human analog, whereby women use a behavioral display of red to signal their sexual interest to men. METHODOLOGY/PRINCIPAL FINDINGS: Three studies tested the hypothesis that women use red clothing to communicate sexual interest to men in profile pictures on dating websites. In Study 1, women who imagined being interested in casual sex were more likely to display red (but not other colors) on their anticipated web profile picture. In Study 2, women who indicated interest in casual sex were more likely to prominently display red (but not other colors) on their actual web profile picture. In Study 3, women on a website dedicated to facilitating casual sexual relationships were more likely to prominently exhibit red (but not other colors) than women on a website dedicated to facilitating marital relationships. CONCLUSIONS/SIGNIFICANCE: These results establish a provocative parallel between women and non-human female primates in red signal coloration in the mating game. This research shows, for the first time, a functional use of color in women's sexual self-presentation, and highlights the need to extend research on color beyond physics, physiology, and preference to psychological functioning.
