Abstract:Facial transplantation is emerging as a therapeutic option for self-inflicted gunshot wounds. The self-inflicted nature of this injury raises questions about the appropriate role of self-harm in determining patient eligibility. Potential candidates for facial transplantation undergo extensive psychosocial screening. The presence of a self-inflicted gunshot wound warrants special attention to ensure that a patient is prepared to undergo a demanding procedure that poses significant risk, as well as stringent lifelong management. Herein, we explore the ethics of considering mechanism (...) of injury in the patient selection process, referring to the precedent set forth in solid organ transplantation. We also consider the available evidence regarding outcomes of individuals transplanted for self-inflicted mechanisms of injury in both solid organ and facial transplantation. We conclude that while the presence of a self-inflicted gunshot wound is significant in the overall evaluation of the candidate, it does not on its own warrant exclusion from consideration for a facial transplantation.

It has been reported that, on average, most adults recall first memories formed around age 3.5. In general, most first memories are positive. However, whether these first memories tend to be visual or verbal and whether the period for childhood amnesia (CA) is greater for visual or verbal or for positive versus negative memories has not been determined. Because negative, stressful experiences disrupt memory and can injure memory centers such as the hippocampus and amygdala, and since adults who were traumatized (...) or abused during childhood (TA) reportedly suffer memory disturbances, it was hypothesized that those with a history of early trauma might suffer from a lengthier childhood amnesia and form their first recallable memories at a later age as compared to the general population (GP). Because the right hemisphere matures earlier than the language-dominant left hemisphere, and is dominant for visual and emotional memory, as well as the stress reponse, it was hypothesized that first recallable memories would be visual rather than verbal. Lastly, since stress can injure the brain and disrupt memory, it was hypothesized that the traumatized group would demonstrate memory and intellectual disturbances associated with right hemisphere injury as based on WAIS-R, Wechsler Memory Scale, and facial-memory testing. All hypotheses were supported. Positive and visual memories are formed before negative and verbal memories. TA CA offset, on average, is at age 6.1 versus 3.5 for GPs. TA PIQ (performance IQ), short-term visual memory, and facial memory were significantly reduced. (shrink)

Health Care Centres are institutions which, because of their specificity and character, are particularly exposed to various kinds of risk. One of the most important and most frequently used methods of risk management is the black spots method. The research material collected for the study comes from one of the hospitals in Wrocław. All hospital stays of the C22 (Face and Jaw Surgery Ward) and H05 (Injury and Orthopaedics Surgery Ward) settlement groups (DRG) were analysed - a total of 178 (...) hospitalisations. The black spots method was used in the study, which consisted of risk identification, the ordering of threats and proposals for remedial actions. Using the black spots method, it was possible to identify adverse events that occurred during the hospitalisation of patients with H05 and C22 DRGs in the Injury and Orthopaedics Surgery Ward and Facial and Jaw Surgery Ward. In both cases, the treatment costs for patients with complications were higher than for the stays without complications. (shrink)

The metamorphosis of human beings into wolves is well known in mythology, legend, and scripture, and has been extensively surveyed in history, theology, and literature. Werewolf cases have attracted the attention of both ancient and modern physicians, particularly during the development of modern psychiatry and behavioral neurology. Some writers have suggested that lycanthropes suffered from schizophrenia or had intentionally or involuntarily ingested hallucinogens. Hysteria and affective disorder, either mania or intense depression, could also be invoked as causes. Lycanthropy has often (...) been linked with, and sometimes treated by, henbane and nightshade, and its manifestations could be explained in terms of atropinic delirium. Discoloration of teeth and urine, bizarre behavior, nocturnal wandering, and episodic skin and facial changes have suggested a role for porphyria in the werewolf transformation. Through many historical periods and cultures, persons believed to be werewolves have reportedly exhibited alterations in consciousness, depersonalization and derealization, acute anxiety and agitation, preoccupation with demonic possession, and compulsive or perseverative behavior, sometimes of a violent, sexually deviant or impulsive nature. Such features of werewolf behavior might also be explained by ictal and interictal manifestations of complex partial seizures, or as symptoms of the episodic dyscontrol syndrome associated with frontal lobe or limbic system disease or injury. Lycanthropy was often considered a manifestation of demonic possession or a consequence or indication of participation in necromancy. As such, self-proclaimed or suspected werewolves were often persecuted along with other practitioners of the black arts. It is generally believed that such persecution represented the last efflorescence of medieval demonology, but it has also been suggested that clinical description of illnesses of diabolical origin was part of the evolution of Renaissance medicine from the Galenic past toward the scientifically-based future.

The face is the first thing that others notice and remember about a person. This is true for the severely facially burned patient, with disfigurement, impaired self-esteem and body image. They and others suffer from chronic devastating facial sequelae resulting from tumors, burns, or congenital malformations and trauma, e.g. ballistic injury to the face. Face transplantation is considered a way to restore eating, swallowing, and speech, and to reestablish esthetics.Alongside these vital bodily functions, the face plays a remarkable role (...) in a person’s identity.

The lack of access to gender-affirming surgery represents a significant unmet health care need within the transgender community, frequently resulting in depression and self-destructive behavior. While some transgender people may have access to gender reassignment surgery, an overwhelming majority cannot afford facial feminization surgery. The former may be covered as a “medical necessity,” but FFS is considered “cosmetic” and excluded from insurance coverage. This demarcation between “necessity” and “cosmetic” in transgender health care based on specific body parts is in (...) direct opposition to the scientific community’s understanding of gender dysphoria and professional guidelines for transgender health. GRS affects one’s ability to function in an intimate relationship, while FFS has the same impact on social interactions an, therefore may have a far greater implication for one’s quality of life. FFS is a cost-effective intervention that needs to be covered by insurance policies. The benefits of such coverage far exceed the insignificant costs. (shrink)

Moral injury emerged in the healthcare discussion quite recently because of the difficulties and challenges healthcare workers and healthcare systems face in the context of the COVID-19 pandemic. Moral injury involves a deep emotional wound and is unique to those who bear witness to intense human suffering and cruelty. This article aims to synthesise the very limited evidence from empirical studies on moral injury and to discuss a better understanding of the concept of moral injury, its importance in the healthcare (...) context and its relation to the well-known concept of moral distress. A scoping literature review design was used to support the discussion. Systematic literature searches conducted in April 2020 in two electronic databases, PubMed/Medline and PsychInfo, produced 2044 hits but only a handful of empirical papers, from which seven well-focused articles were identified. The concept of moral injury was considered under other concepts as well such as stress of conscience, regrets for ethical situation, moral distress and ethical suffering, guilt without fault, and existential suffering with inflicting pain. Nurses had witnessed these difficult ethical situations when faced with unnecessary patient suffering and a feeling of not doing enough. Some cases of moral distress may turn into moral residue and end in moral injury with time, and in certain circumstances and contexts. The association between these concepts needs further investigation and confirmation through empirical studies; in particular, where to draw the line as to when moral distress turns into moral injury, leading to severe consequences. Given the very limited research on moral injury, discussion of moral injury in the context of the duty to care, for example, in this pandemic settings and similar situations warrants some consideration.

Research on facial emotion expression has mostly focused on emotion recognition, assuming that a small number of discrete emotions is elicited and expressed via prototypical facial muscle configurations as captured in still photographs. These are expected to be recognized by observers, presumably via template matching. In contrast, appraisal theories of emotion propose a more dynamic approach, suggesting that specific elements of facial expressions are directly produced by the result of certain appraisals and predicting the facial patterns (...) to be expected for certain appraisal configurations. This approach has recently been extended to emotion perception, claiming that observers first infer individual appraisals and only then make categorical emotion judgments based on the estimated appraisal patterns, using semantic inference rules. Here we report two related studies to empirically investigate the facial action unit configurations that are used by actors to convey specific emotions in short affect bursts and to examine to what extent observers can infer a person’s emotions from the predicted facial expression configurations. The results show that 1) professional actors use many of the predicted facial action unit patterns to enact systematically specified appraisal outcomes in a realistic scenario setting, and 2) naïve observers infer the respective emotions based on highly similar facial movement configurations with a degree of accuracy comparable to earlier research findings. Based on estimates of underlying appraisal criteria for the different emotions we conclude that the patterns of facial action units identified in this research correspond largely to prior predictions and encourage further research on appraisal-driven expression and inference.

While numerous studies have examined the relationships between facial actions and emotions, they have yet to account for the ways that specific spontaneous facial expressions map onto emotional experiences induced without expressive intent. Moreover, previous studies emphasized that a fine-grained investigation of facial components could establish the coherence of facial actions with actual internal states. Therefore, this study aimed to accumulate evidence for the correspondence between spontaneous facial components and emotional experiences. We reinvestigated data from (...) previous research which secretly recorded spontaneous facial expressions of Japanese participants as they watched film clips designed to evoke four different target emotions: surprise, amusement, disgust, and sadness. The participants rated their emotional experiences via a self-reported questionnaire of sixteen emotions. These spontaneous facial expressions were coded using the Facial Action Coding System, the gold standard for classifying visible facial movements. We corroborated each facial action that was present in the emotional experiences by applying stepwise regression models. The results found that spontaneous facial components occurred in ways that cohere to the their evolutionary functions based on the rating values of emotional experiences (e.g., the inner brow raiser might be involved in the evaluation of novelty). This study provided new empirical evidence for the correspondence between each spontaneous facial component and first-person internal states of emotion as reported by the expresser. (shrink)

Facial expressions are a vital way for humans to show their perceived emotions. It is convenient for detecting and recognizing expressions or micro-expressions by annotating a lot of data in deep learning. However, the study of video-based expressions or micro-expressions requires that coders have professional knowledge and be familiar with action unit coding, leading to considerable difficulties. This paper aims to alleviate this situation. We deconstruct facial muscle movements from the motor cortex and systematically sort out the relationship (...) among facial muscles, AU, and emotion to make more people understand coding from the basic principles: We derived the relationship between AU and emotion based on a data-driven analysis of 5,000 images from the RAF-AU database, along with the experience of professional coders.We discussed the complex facial motor cortical network system that generates facial movement properties, detailing the facial nucleus and the motor system associated with facial expressions.The supporting physiological theory for AU labeling of emotions is obtained by adding facial muscle movements patterns.We present the detailed process of emotion labeling and the detection and recognition of AU.Based on the above research, the video's coding of spontaneous expressions and micro-expressions is concluded and prospected.

Many nonhuman animals produce facial expressions which sometimes bear clear resemblance to the facial expressions seen in humans. An understanding of this evolutionary continuity between species, and how this relates to social and ecological variables, can help elucidate the meaning, function, and evolution of facial expression. This aim, however, requires researchers to overcome the theoretical and methodological differences in how human and nonhuman facial expressions are approached. Here, we review the literature relating to nonhuman facial (...) expressions and suggest future directions that could facilitate a better understanding of facial expression within an evolutionary context.

Since Jonathan Shay's work with Vietnam veterans, moral injury has largely focused on the harm done to soldiers' moral character through their participation in warfare. This essay argues for the inclusion of noncombatants in the scope of inquiry involving moral injury. Specifically, it argues for the necessity of ordinary citizens assuming responsibility for the moral injury done to soldiers and civilians alike in the post‐9/11 wars.

This paper proposes that human expression of pain in the presence or absence of caregivers, and the detection of pain by observers, arises from evolved propensities. The function of pain is to demand attention and prioritise escape, recovery, and healing; where others can help achieve these goals, effective communication of pain is required. Evidence is reviewed of a distinct and specific facial expression of pain from infancy to old age, consistent across stimuli, and recognizable as pain by observers. Voluntary (...) control over amplitude is incomplete, and observers can better detect pain that the individual attempts to suppress rather than amplify or simulate. In many clinical and experimental settings, the facial expression of pain is incorporated with verbal and nonverbal vocal activity, posture, and movement in an overall category of pain behaviour. This is assumed by clinicians to be under operant control of social contingencies such as sympathy, caregiving, and practical help; thus, strong facial expression is presumed to constitute an attempt to manipulate these contingencies by amplification of the normal expression. Operant formulations support skepticism about the presence or extent of pain, judgments of malingering, and sometimes the withholding of caregiving and help. To the extent that pain expression is influenced by environmental contingencies, however, could equally plausibly constitute the release of suppression according to evolved contingent propensities that guide behaviour. Pain has been largely neglected in the evolutionary literature and the literature on expression of emotion, but an evolutionary account can generate improved assessment of pain and reactions to it.

If I am injured in the course of medical investigation or treatment, I may be eligible to receive compensation for some of the adverse consequences of my injury—at least, if I live in a developed country.

However, even within the developed world, there is considerable variation in the eligibility criteria for compensation. Different countries would, for example, respond very differently to the following pair of (...) cases... (shrink)

The use of facial recognition technology (FRT) as a form of intelligence has recently made a prominent public appearance in the theater of war. During the early months of Russia's invasion of Ukraine, Ukrainian authorities relied on FRT as part of the country's defensive activities, harnessing the technology for a variety of purposes, such as unveiling covert Russian agents operating amid the Ukrainian population; revealing the identity of Russian soldiers who committed war crimes; and even identifying dead Russian soldiers. (...) This constellation of uses of FRT—in a war increasingly waged on the digital and information front—warrants ethical examination. The essay discusses some of the most serious concerns with FRT in the context of war, including the infringement of informational privacy; the indiscriminate and disproportionate harms it may inflict, particularly when the technology is coupled with social media intelligence; and the potential abuse of the technology once the fog of war dissipates. Some of these concerns parallel those to be found in nations that are not engulfed in war, but others are unique to war-torn settings. (shrink)

Following Yik and Russell (1999) a judgement paradigm was used to examine to what extent differential accuracy of recognition of facial expressions allows evaluation of the well-foundedness of different theoretical views on emotional expression. Observers judged photos showing facial expressions of seven emotions on the basis of: (1) discrete emotion categories; (2) social message types; (3) appraisal results; or (4) action tendencies, and rated their confidence in making choices. Emotion categories and appraisals were judged significantly more accurately and (...) confidently than messages or action tendencies. These results do not support claims of primacy for message or action tendency views of facial expression. Based on a componential model of emotion it is suggested that judges can infer components from categories and vice versa. (shrink)

In this article, I confront Flanigan’s recent attempt to show, not merely that women have a right to commit prenatal injury, but also that women who act on this right are praiseworthy and should not be criticized for this injury. I show that Flanigan’s arguments do not work, and I establish presumptive grounds against any such right, namely: prenatal injury, by definition, involves intentional or negligent harm and, as such, may be subsumed under a wider class of actions that are (...) presumptively wrong.

It is hypothesized that human faces judged to be attractive by people possess two features—averageness and symmetry—that promoted adaptive mate selection in human evolutionary history by way of production of offspring with parasite resistance. Facial composites made by combining individual faces are judged to be attractive, and more attractive than the majority of individual faces. The composites possess both symmetry and averageness of features. Facial averageness may reflect high individual protein heterozygosity and thus an array of proteins to (...) which parasites must adapt. Heterozygosity may be an important defense of long-lived hosts against parasites when it occurs in portions of the genome that do not code for the essential features of complex adaptations. In this case heterozygosity can create a hostile microenvironment for parasites without disrupting adaptation. Facial bilateral symmetry is hypothesized to affect positive beauty judgments because symmetry is a certification of overall phenotypic quality and developmental health, which may be importantly influenced by parasites. Certain secondary sexual traits are influenced by testosterone, a hormone that reduces immunocompetence. Symmetry and size of the secondary sexual traits of the face (e.g., cheek bones) are expected to correlate positively and advertise immunocompetence honestly and therefore to affect positive beauty judgments. Facial attractiveness is predicted to correlate with attractive, nonfacial secondary sexual traits; other predictions from the view that parasite-driven selection led to the evolution of psychological adaptations of human beauty perception are discussed. The view that human physical attractiveness and judgments about human physical attractiveness evolved in the context of parasite-driven selection leads to the hypothesis that both adults and children have a species-typical adaptation to the problem of identifying and favoring healthy individuals and avoiding parasite-susceptible individuals. It is proposed that this adaptation guides human decisions about nepotism and reciprocity in relation to physical attractiveness. (shrink)

Although the prevalence of facial recognition-based COVID-19 surveillance tools and techniques, China does not have a facial recognition law to protect its residents’ facial data. Oftentimes, neither the public nor the government knows where people’s facial images are stored, how they have been used, who might use or misuse them, and to what extent. This reality is alarming, particularly factoring in the wide range of unintended consequences already caused by good-intentioned measures and mandates amid the pandemic. (...) Biometric data are matters of personal rights and national security. In light of worrisome technologies such as deep-fake pornography, the protection of biometric data is also central to the protection of the dignity of the citizens and the government, if not the industry as well. This paper discusses the urgent need for the Chinese government to establish rigorous and timely facial recognition laws to protect the public’s privacy, security, and dignity amid COVID-19 and beyond.

This article offers suggestions for categorizing combat-related moral injuries, highlights possible causes of these injuries in veterans, and touches upon broadly-conceived measures to prevent and repair them. The first part identifies three prevailing definitions – lost trust, guilt, and harm to one’s capacity for right action and moral virtue – and argues for an emphasis on the latter. In service of highlighting areas for future empirical research and clinical awareness, the second part outlines possible veteran-related causes associated with (...) these three definitions, including unwarranted distrust of authorities, misapplying the theodicy problem to human acts, undue survivor’s guilt, wars that fail to meet ad bellum criteria, causing permissible collateral damage, and killing combatants without regret and for pleasure.

In this chapter, the authors argue that the concept of “moral injury” needs regimentation: Current definitions are both too broad and too narrow. They are too broad because they ignore or conflate important differences between the kinds of moral conflicts discussed in the literature. They are too narrow because they exclude the possibility of moral injury in the absence of internal moral conflict. The authors argue that it is necessary to first develop a conception of moral health, and they propose (...) a Strawsonian conception of moral health as the ability to participate in the moral community. The account offered in this chapter thus includes some cases that are not recognized as moral injuries in the literature and rejects some cases that are commonly described as moral injuries.

Prior studies provide consistent evidence of deficits for psychopaths in processing verbal emotional material but are inconsistent regarding nonverbal emotional material. To examine whether psychopaths exhibit general versus specific deficits in nonverbal emotional processing, 34 psychopaths and 33 nonpsychopaths identified with Hare's (R. D. Hare, 1991) Psychopathy Checklist-Revised were asked to complete a facial affect recognition test. Slides of prototypic facial expressions were presented. Three hypotheses regarding hemispheric lateralization anomalies in psychopaths were also tested (right-hemisphere dysfunction, reduced lateralization, (...) and reversed lateralization). Psychopaths were less accurate than nonpsychopaths at classifying facial affect under conditions promoting reliance on right-hemisphere resources and displayed a specific deficit in classifying disgust. These findings demonstrate that psychopaths exhibit specific deficits in nonverbal emotional processing. (shrink)

Drawing on research reviewed in this special section, the present article discusses how various contextual factors impact on production and decoding of emotion-related facial activity. Although emotion-related variables often contribute to activation of prototypical “emotion expressions” and perceivers can often infer emotional meanings from these facial configurations, neither process is invariant or direct. Many facial movements are directed towards or away from events in the shared environment, and their effects depend on these relational orientations. Facial activity (...) is not only a medium for descriptive representation of internal affective states, but also a means of adjusting to, and operating on, external objects, and of influencing other people’s appraisals of those objects.

This study was designed to test three competing hypotheses (impaired configural processing; impaired Theory of Mind; atypical amygdala functioning) to explain the basic facial expression recognition profile of adults with autism spectrum disorders (ASD). In Experiment 1 the Ekman and Friesen (1976) series were presented upright and inverted. Individuals with ASD were significantly less accurate than controls at recognising upright facial expressions of fear, sadness and disgust and their pattern of errors suggested some configural processing difficulties. Impaired recognition (...) of inverted facial expressions suggested some additional difficulties processing the facial features. Unexpectedly, the clinical group misidentified fear as anger. In Experiment 2 feature processing of facial expressions was investigated by presenting stimuli in a piecemeal fashion, starting with either just the eyes or the mouth. Individuals with ASD were impaired at recognising fear from the eyes and disgust from the mouth; they also confused fearful eyes as being angry. The findings are discussed in terms of the three competing hypotheses tested. (shrink)

An analysis of the identity issues involved in facial allograft transplantation is provided in this paper. The identity issues involved in organ transplantation in general, under both theoretical accounts of personal identity and subjective accounts provided by organ recipients, are examined.

Recipients of (...) class='Hi'>facial allograft transplantation have the potential to feel that their identity is a mix between their own and the donor’s, and the donor’s family is potentially likely to feel that their loved one “lives on”. It is also argued that facial allograft transplantation allows the recipients to regain an identity, because they can now be seen in the social world. Moreover, they may regain expressivity, allowing for them to be seen even more by others, and to regain an identity to an even greater extent. Informing both recipients and donors about the role that identity plays in facial allograft transplantation could enhance the consent process for facial allograft transplantation and donation.

ABSTRACTPrior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and (...) neutral faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple a... (shrink)

This article aims to determine to what extent photographic practices in psychology, psychiatry and physiology contributed to the definition of the external bodily signs of passions and emotions in the second half of the 19th century in France.

Emotions are multimodal processes that play a crucial role in our everyday lives. Recognizing emotions is becoming more critical in a wide range of application domains such as healthcare, education, human-computer interaction, Virtual Reality, intelligent agents, entertainment, and more. Facial macro-expressions or intense facial expressions are the most common modalities in recognizing emotional states. However, since facial expressions can be voluntarily controlled, they may not accurately represent emotional states. Earlier studies have shown that facial micro-expressions are (...) more reliable than facial macro-expressions for revealing emotions. They are subtle, involuntary movements responding to external stimuli that cannot be controlled. This paper proposes using facial micro-expressions combined with brain and physiological signals to more reliably detect underlying emotions. We describe our models for measuring arousal and valence levels from a combination of facial micro-expressions, Electroencephalography (EEG) signals, galvanic skin responses (GSR), and Photoplethysmography (PPG) signals. We then evaluate our model using the DEAP dataset and our own dataset based on a subject-independent approach. Lastly, we discuss our results, the limitations of our work, and how these limitations could be overcome. We also discuss future directions for using facial micro-expressions and physiological signals in emotion recognition. (shrink)

In this article, we review empirical evidence regarding the relationship between facial expression and emotion during infancy. We focus on differential emotions theory’s view of this relationship because of its theoretical and methodological prominence. We conclude that current evidence fails to support its proposal regarding a set of pre-specified facial expressions that invariably reflect a corresponding set of discrete emotions in infants. Instead, the relationship between facial expression and emotion appears to be more complex. Some facial (...) expressions may have different meanings in infants than in children and adults. In addition, nonemotion factors may sometimes lead to the production of “emotional” facial expressions. We consider alternative perspectives on the nature of emotion and emotional expression in infancy with particular focus on differentiation and dynamical systems approaches. (shrink)

Philosophers are wont to say that certain concepts, e.g., the concept of pain, exhibit ‘first/third-person asymmetry’, whereas others, e.g., the concept of injury, do not. The question I wish to address here concerns the status of such claims. They are commonly seen as nothing more than summary reports of how the relevant words are ordinarily used: as statements of ‘grammatical fact’. I want to argue against this view of their status.

In this article, I undertake three main tasks. First, I argue that, contrary to the standard view, moral injury is not a species of PTSD (post-traumatic stress disorder) but rather, on the most coherent conception of moral injury, PTSD is (in effect) a species of moral injury. In doing so, I make use of the notion of caring deeply about something or someone worthy of being cared deeply about. Second, I consider so-called “dirty hands” actions in police work and in (...) war, and distinguish these from the morally legitimate, but harmful, actions of police officers and of war fighters, such as the morally legitimate use of coercive force and lethal force (respectively). While the morally legitimate use of harmful methods is constitutive of these occupational roles, “dirty hands” methods are not. Roughly speaking, a “dirty hands” action is one that is morally wrong and (typically) unlawful but done for the sake of a good outcome. Both categories of action are conducive to moral injury, but “dirty hands” actions much more so, especially given the slippery moral slope from “dirty hands” actions to egregious moral wrongdoing. Third, I offer some recommendations for reducing moral injury among police officers and war fighters. (shrink)

Facial expressions of pain may be best conceptualized as an example of an evolved propensity to communicate distress, rather than as a distinct category of facial expression. The operant model goes beyond the evolutionary account, as it can explain how the (facial) expression of pain can become maladaptive as a result of its capability to elicit attention and caring behavior in the observer.

This study explores the evolutionary-based hypothesis that facial attractiveness (a guiding force in mate selection) is a cue for physical fitness (presumably an important contributor to mate value in ancestral times). Since fluctuating asymmetry, a measure of developmental stability, is known to be a valid cue for fitness in several biological domains, we scrutinized facial asymmetry as a potential mediator between attractiveness and fitness. In our sample of young women, facial beauty indeed indicated physical fitness. The relationships (...) that pertained to asymmetry were in the expected direction. However, a closer analysis revealed that facial asymmetry did not mediate the relationship between fitness and attractiveness. Unexpected problems regarding the measurement of facial asymmetry are discussed. (shrink)

This article discusses how research on the image-based analysis of facial images has informed this debate by demonstrating that a single representational system for facial identity and facial expression is not only computationally viable, but can simulate existing cognitive data demonstrating apparent dissociable processing of these two facial properties. It discusses the increasing number of cognitive studies that provide support for this view. Neuropsychological case studies of brain-injured patients and provide limited evidence for separate visual routes (...) processing facial identity and facial expression. It deals with neuroimaging studies addressing both facial identity and facial expression processing which shows that the fusiform gyrus contributes to the recognition of both facial properties. Research continues to reinforce the proposal that a common visual framework supports the representation of at least some aspects of facial identity and facial expression. (shrink)

That facial expressions are universal emotion signals has been supported by observers agreeing on the emotion mimed by actors. We show that actors can mime a diverse range of states: emotions, cognitions, physical states, and actions. English, Hindi, and Malayalam speakers viewed 25 video clips and indicated the state conveyed. Within each language, at least 23 of the 25 clips were recognised above chance and base rate. Facial expressions of emotions are not special in their recognisability, and it (...) is miming that may be the universal human ability. (shrink)

To define the determinants of impaired facial emotion recognition (FER) in patients with mesial temporal lobe epilepsy associated with hippocampal sclerosis (MTLE-HS), we examined 76 patients with unilateral MTLE-HS, 36 prior to antero-mesial temporal lobectomy (AMTL) and 40 after AMTL, and 28 healthy control subjects with a FER test consisting of 60 items (20 each for anger, fear, and happiness). Mean percentages of the accurate responses were calculated for different subgroups: right vs. left MTLE-HS, early (age at onset <6 (...) years) vs. late-onset, and before vs. after AMTL. After controlling for years of education, duration of epilepsy and number of antiepileptic drugs (AEDs) taken, on multivariate analysis, fear recognition was profoundly impaired in early-onset right MTLE-HS patients compared to other MTLE patients and control subjects. Happiness recognition was significantly better in post-AMTL MTLE-HS patients compared to pre-AMTL patients while anger and fear recognition did not differ. We conclude that patients with right MTLE-HS with age at seizure onset <6 years are maximally predisposed to impaired fear recognition. In them, right AMTL does not further worsen FER abilities. Longitudinal studies comparing FER in the same patients before and after AMTL will be required to refine and confirm our cross-sectional observations. (shrink)
