Odours alter evaluations of concurrent visual stimuli. However, neural mechanisms underlying the effects of congruent and incongruent odours on facial expression perception are not clear. Moreover, the influence of emotional faces on odour perception is not established. We investigated the effects of one pleasant and one unpleasant odour paired with happy and disgusted faces, on subjective ratings and ERP responses to faces. Participants rated the pleasantness of happy and disgusted faces that appeared during 3second pleasant or unpleasant odour pulses, or without odour...

Affective face perception is influenced by nonfacial contextual elements. However, investigations often conflate body posture and emotion scene, making it unclear whether posture or the combination of posture and scene produces perception-altering effects. This study examined adults' categorizations of disgust facial expressions superimposed onto isolated emotion postures or postures embedded in emotion scenes. Results indicated that emotional postures exerted a significant contextual effect on adults' emotion categorizations of disgust faces...

INTRODUCTION: Congenital central hypoventilation syndrome (CCHS) is a rare genetic disorder due to paired-like homeobox gene (PHOX2B) mutations. CCHS patients suffer from dysregulation of the autonomic nervous system characterized by the absence of or extremely reduced response to hypercapnia and hypoxia, with neuropsychological deficits. The aim of this exploratory study is to describe the longitudinal neuropsychological profile and its correlations with magnetic resonance imaging (MRI) of a child with CCHS with a PHOX2B mutation...

Disgust is a core emotion evolved to detect and avoid the ingestion of poisonous food as well as the contact with pathogens and other harmful agents. Previous research has shown that multisensory presentation of olfactory and visual information may strengthen the processing of disgust-relevant information. However, it is not known whether these findings extend to dynamic facial stimuli that changes from neutral to emotionally expressive, or if individual differences in trait body odor disgust may influence the processing of disgust-related information...

Transcranial magnetic stimulation (TMS) and neuroimaging studies suggest a role of the right occipital face area (rOFA) in early facial feature processing. However, the degree to which rOFA is necessary for the encoding of facial identity has been less clear. Here we used a state-dependent TMS paradigm, where stimulation preferentially facilitates attributes encoded by less active neural populations, to investigate the role of the rOFA in face perception and specifically in image-independent identity processing...

Previous findings suggest that older adults show impairments in the social perception of faces, including the perception of emotion and facial identity. The majority of this work has tended to examine performance on tasks involving young adult faces and prototypical emotions. While useful, this can influence performance differences between groups due to perceptual biases and limitations on task performance. Here we sought to examine how typical aging is associated with the perception of subtle changes in facial happiness and facial identity in older adult faces...

Difficulties in emotion perception are commonly observed in autism spectrum disorder. However, it is unclear whether these difficulties can be attributed to a general problem of relating to emotional states, or whether they specifically concern the perception of others' expressions. This study addressed this question in the context of pain, a sensory and emotional state with strong social relevance. We investigated pain evaluation in self and others in 16 male individuals with autism spectrum disorder and 16 age- and gender-matched individuals without autism spectrum disorder...

BACKGROUND: New onset of mood and behavioral changes in middle-aged patients are frequently the first manifestations of an unrecognized neurocognitive disorder. Impairment of social cognition, the cognitive ability to process social information coming from others, such as emotions, to attribute mental states to others, and to respond appropriately to them, is often at the origin of behavioral manifestations in neurodegenerative disorders. METHODS: This paper reviews the current literature on social cognition impairment in neurocognitive disorders, particularly in prodromal stages of behavioral-variant frontotemporal dementia (bvFTD), Alzheimer's disease (AD), idiopathic Parkinson's disease (IPD), and Lewy body dementia (LBD)...

<p>The psychosocial health of patients undergoing cosmetic procedures has often been linked to a host of pre-existing conditions, including the type of procedure being performed. Age, gender, and the psychological state of the patients also contribute to the perceived outcome. Specifically, the presence or absence of Body Dysmorphic Disorder (BDD) has been identified as an independent marker for unhappiness following cosmetic procedures.1 However, no study has, to our knowledge, identified a more precise indicator that is associated with higher rates of patient dissatisfaction from cosmetic procedure...

The current study aims to identify the relationships between implicit leadership theoretical (ILT) prototypes / anti-prototype and five facial features (i.e., nasion, upper nose, lower nose, and upper lip) of a leader from a different race than respondents. A sample of 81 Asian respondents viewed a 30-second video of a Caucasian female who in a non-engaging manner talked about her career achievements. As participants watch the video, their eye movements were recorded via an eye tracking devise. While previous research has identified that ILT influences perceptional and attitudinal ratings of leaders, the current study extends these findings by confirming the impact of ILT on the gaze patterns of other race participants, who appear to adopt system one type thinking...

In this study, we explore the automaticity of encoding for different facial characteristics and ask whether it is influenced by face familiarity. We used a matching task in which participants had to report whether the gender, identity, race, or expression of two briefly presented faces was the same or different. The task was made challenging by allowing nonrelevant dimensions to vary across trials. To test for automaticity, we compared performance on trials in which the task instruction was given at the beginning of the trial, with trials in which the task instruction was given at the end of the trial...

Non-verbal signals such as facial expressions are of paramount importance for social encounters. Their perception predominantly occurs without conscious awareness and is effortlessly integrated into social interactions. In other words, face perception is intuitive. Contrary to classical intuition tasks, this work investigates intuitive processes in the realm of every-day type social judgments. Two differently instructed groups of participants judged the authenticity of emotional facial expressions, while their eye movements were recorded: an 'intuitive group,' instructed to rely on their "gut feeling" for the authenticity judgments, and a 'deliberative group,' instructed to make their judgments after careful analysis of the face...

Background: Acne vulgaris is a common, often socially distressing skin condition primarily seen in young adults. Quality of life studies have shown that people with acne are more introverted with increased social setting anxiety compared to a control group. Unfortunately, patients with acne may have residual postinflammatory hyperpigmentation, amplifying impaired psychosocial effects. Objective: To quantify the impact of postinflammatory hyperpigmentation in patients with acne using a psychometric scale. Design: A clinic-based survey was conducted among US adults with facial acne and postinflammatory hyperpigmentation...

OBJECTIVE: Abnormal prefrontal-limbic brain activation in response to facial expressions has been reported in pediatric bipolar disorder (BD). However, it is less clear whether these abnormalities exist prior to onset of mania, thus representing a biomarker predicting development of BD. METHODS: We examined brain activation in 50 youth at high risk for BD (HR-BD), compared with 29 age- and gender-matched healthy control (HC) subjects. HR-BD was defined as having a parent with BD, as well as current mood or attentiondeficit/ hyperactivity disorder (ADHD) symptoms, or a history of at least one depressive episode...

Although maxillomandibular advancement (MMA) is an orthognathic surgical procedure used to manage obstructive sleep apnea (OSA) in individuals who are noncompliant with continuous positive airway pressure therapy, simple MMA encounters problems in terms of aesthetic outcomes in Asian populations with preexisting dentoalveolar protrusion. Our current prospective investigation describes changes in posterior pharyngeal space and aesthetic outcomes after counterclockwise rotational orthognathic surgery, which is known to be quite difficult in terms of the maintenance of the skeletal stability in skeletal class II patients with OSA...

OBJECTIVE: This study aims at comparing the perception of orthodontists, maxillofacial surgeons, visual artists and laypersons when evaluating the influence of sagittal position of the mandible - in lateral view - in facial attractiveness; at a job hiring; and in the perception of socioeconomic profile. METHODS: A black male, a white male, a black female and a white female with harmonic faces served as models to obtain a facial profile photograph. Each photograph was digitally manipulated to obtain seven facial profiles: an ideal, three simulating mandibular advancement and three simulating mandibular retrusion, producing 28 photographs...

Facial expressions of emotion are nonverbal behaviors that allow us to interact efficiently in social life and respond to events affecting our welfare. This article reviews 21 studies, published between 1932 and 2015, examining the production of facial expressions of emotion by blind people. It particularly discusses the impact of visual experience on the development of this behavior from birth to adulthood. After a discussion of three methodological considerations, the review of studies reveals that blind subjects demonstrate differing capacities for producing spontaneous expressions and voluntarily posed expressions...

A large body of evidence supports an important role for CGRP in migraine pathophysiology. This evidence gave rise to a global effort to develop a new generation of therapeutics that inhibit the interaction of CGRP with its receptor in migraineurs. Recently, a new class of such drugs, humanized monoclonal anti-CGRP antibodies (CGRP-mAb) were found to be effective in reducing the frequency of migraine. The purpose of this study was to better understand how the CGRP-mAb fremanezumab (TEV-48125) modulates meningeal sensory pathways...
