Optimizing future well-being with artificial intelligence: self-organizing maps (SOMs) for the identification of islands of emotional stability.

In this article, we present a deep learning model of human psychology that can predict one's current age and future well-being. We used the model to demonstrate that one's baseline well-being is not the determining factor of future well-being, as posited by hedonic treadmill theory. Further, we have created a 2D map of human psychotypes and identified the regions that are most vulnerable to depression. This map may be used to provide personalized recommendations for maximizing one's future well-being.

A Novel Test of the Duchenne Marker: Smiles After Botulinum Toxin Treatment for Crow's Feet Wrinkles.

Smiles that vary in muscular configuration also vary in how they are perceived. Previous research suggests that "Duchenne smiles," indicated by the combined actions of the orbicularis oculi (cheek raiser) and the zygomaticus major muscles (lip corner puller), signal enjoyment. This research has compared perceptions of Duchenne smiles with non-Duchenne smiles among individuals voluntarily innervating or inhibiting the orbicularis oculi muscle. Here we used a novel set of highly controlled stimuli: photographs of patients taken before and after receiving botulinum toxin treatment for crow's feet lines that selectively paralyzed the lateral orbicularis oculi muscle and removed visible lateral eye wrinkles, to test perception of smiles. Smiles in which the orbicularis muscle was active (prior to treatment) were rated as more felt, spontaneous, intense, and happier. Post treatment patients looked younger, although not more attractive. We discuss the potential implications of these findings within the context of emotion science and clinical research on botulinum toxin.

Cosmetics as a feature of the extended human phenotype: modulation of the perception of biologically important facial signals.

Research on the perception of faces has focused on the size, shape, and configuration of inherited features or the biological phenotype, and largely ignored the effects of adornment, or the extended phenotype. Research on the evolution of signaling has shown that animals frequently alter visual features, including color cues, to attract, intimidate or protect themselves from conspecifics. Humans engage in conscious manipulation of visual signals using cultural tools in real time rather than genetic changes over evolutionary time. Here, we investigate one tool, the use of color cosmetics. In two studies, we asked viewers to rate the same female faces with or without color cosmetics, and we varied the style of makeup from minimal (natural), to moderate (professional), to dramatic (glamorous). Each look provided increasing luminance contrast between the facial features and surrounding skin. Faces were shown for 250 ms or for unlimited inspection time, and subjects rated them for attractiveness, competence, likeability and trustworthiness. At 250 ms, cosmetics had significant positive effects on all outcomes. Length of inspection time did not change the effect for competence or attractiveness. However, with longer inspection time, the effect of cosmetics on likability and trust varied by specific makeup looks, indicating that cosmetics could impact automatic and deliberative judgments differently. The results suggest that cosmetics can create supernormal facial stimuli, and that one way they may do so is by exaggerating cues to sexual dimorphism. Our results provide evidence that judgments of facial trustworthiness and attractiveness are at least partially separable, that beauty has a significant positive effect on judgment of competence, a universal dimension of social cognition, but has a more nuanced effect on the other universal dimension of social warmth, and that the extended phenotype significantly influences perception of biologically important signals at first glance and at longer inspection.

Facial attractiveness ratings and perfectionism in body dysmorphic disorder and obsessive-compulsive disorder.

Individuals with body dysmorphic disorder (BDD) suffer from a preoccupation about imagined or slight appearance flaws. We evaluated facial physical attractiveness ratings and perfectionistic thinking among individuals with BDD (n=19), individuals with obsessive-compulsive disorder (OCD; n=21), and mentally healthy control participants (n=21). We presented participants with photographs displaying faces varying in facial attractiveness (attractive, average, unattractive) and asked them to rate them in terms of their physical attractiveness. We further examined how the participants evaluated their own physical attractiveness, relative to independent evaluators (IEs). As predicted, BDD participants perceived their own attractiveness as significantly lower than did the IEs, and they rated photographs from the category "Attractive" as significantly more attractive than did the other groups. Furthermore, both clinical groups were characterized by more perfectionistic thinking than controls. These findings mostly support cognitive-behavioral models of BDD that suggest that individuals with BDD exhibit perfectionistic thinking and maladaptive attractiveness beliefs.

Emotion recognition bias for contempt and anger in body dysmorphic disorder.

Body dysmorphic disorder (BDD) patients are preoccupied with imagined defects or flaws in appearance (e.g., size or shape of nose). They are afraid of negative evaluations by others and often suffer significant morbidity including hospitalization and suicide attempts. Many patients experience ideas of reference, e.g., they often believe others take special notice of their "flaw". Facial expressions play an important role in conveying negative or positive feelings, and sympathy or rejection. In this study, we investigated emotion recognition deficits in 18 BDD patients and 18 healthy controls. Participants were presented with two questionnaires accompanying facial photographs. One questionnaire included self-referent scenarios ("Imagine that the bank teller is looking at you. What is his facial expression like?"), whereas the other one included other-referent scenarios ("Imagine that the bank teller is looking at a friend of yours," etc.), and participants were asked to identify the corresponding emotion (e.g., anger, contempt, neutral, or surprise). Overall, BDD patients, relative to controls, had difficulty identifying emotional expressions in self-referent scenarios. They misinterpreted more expressions as contemptuous and angry in self-referent scenarios than did controls. However, they did not have significantly more difficulties identifying emotional expressions in other-referent scenarios than controls. Thus, poor insight and ideas of reference, common in BDD, might be related to a bias for misinterpreting other people's emotional expressions as negative. Perceiving others as rejecting might reinforce concerns about one's personal perceived ugliness and social desirability.

Emotion recognition deficits in body dysmorphic disorder.

Patients with Body Dysmorphic Disorder (BDD) are characterized by excessive concerns about imagined defects in their appearance, most commonly, facial features. In this study, we investigated (1) the ability to identify facial expressions of emotion, and (2) to discriminate single facial features in BDD patients, Obsessive-Compulsive Disorder (OCD) patients, and in healthy control participants. Specifically, their ability for general facial feature discrimination was assessed using the Short Form of the Benton Facial Recognition Test (Benton AL, Hamsher KdeS, Varney NR, Spreen O. Contributions to neuropsychological assessment: a clinical manual. New York: Oxford University Press; 1983). However, findings of the BFRT indicate no differences among the groups. Moreover, participants were presented with facial photographs from the Ekman and Friesen (Ekman P, Friesen W. Unmasking the face: a guide to recognizing emotions from facial cues. Englewood Cliffs, NJ: Prentice-Hall; 1975 and Ekman P, Friesen W. Pictures of facial affect. Palo Alto: Consulting Psychologists Press, 1976) series and were asked to identify the corresponding emotion. The BDD group was less accurate than the control group, but not the OCD group, in identifying facial expressions of emotion. Relative to the control and OCD groups, the BDD group more often misidentified emotional expressions as angry. In contrast to the findings of Sprengelmeyer et al. [Proc. Royal Soc. London Series B: Biol. Sci. 264 (1997),1767], OCD patients did not show a disgust recognition deficit. Poor insight and ideas of reference, common in BDD, might partly result from an emotion recognition bias for angry expressions. Perceiving others as angry and rejecting might reinforce concerns about one's personal ugliness and social desirability.
