Objective: To explore the clinical and molecular genetic features of patients with Alagille syndrome (AS). Methods: The clinical data of eleven pediatric patients, who were suspected to have AS at the Department of Pediatrics in the First Affiliated Hospital of Jinan University from August 2010 to March 2017, were collected and analyzed. Genomic DNA was extracted from peripheral blood leukocytes of the patients and their parents. For 5 patients collected before March 2006, all JAG1 exons and their flanking sequences were directly sequenced...

To investigate the emotional face processing in patients with schizophrenia, the preattentive automatic processing of emotional faces in individuals with schizophrenia was compared with that of age-matched healthy control group as indexed by the expressional mismatch negativity (EMMN) elicited by facial expressions. Compared with neutral faces as standard stimuli, deviant emotional faces elicited posterior EMMN between 150 and 500 ms after stimuli onset, with larger amplitudes for sad than happy deviant faces...

Although it is widely believed that females outperform males in the ability to recognize other people's emotions, this conclusion is not well supported by the extant literature. The current study sought to provide a strong test of the female superiority hypothesis by investigating sex differences in emotion recognition for five basic emotions using stimuli well-calibrated for individual differences assessment, across two expressive domains (face and body), and in a large sample (N = 1,022: Study 1). We also assessed the stability and generalizability of our findings with two independent replication samples (N = 303: Study 2, N = 634: Study 3)...

People high in social anxiety experience fear of social situations due to the likelihood of social evaluation. Whereas happy faces are generally processed very quickly, this effect is impaired by high social anxiety. Mouth regions are implicated during emotional face processing, therefore differences in mouth salience might affect how social anxiety relates to emotional face discrimination. We designed an emotional facial expression recognition task to reveal how varying levels of sub-clinical social anxiety (measured by questionnaire) related to the discrimination of happy and fearful faces, and of happy and angry faces...

The major aims of this study were to examine how, if at all, having higher levels of PTSD would be associated with performance on a facial affect recognition task in which facial expressions of emotion are superimposed on emotionally valenced, non-face images. College students with trauma histories (N = 90) completed a facial affect recognition task as well as measures of exposure to traumatic events, and PTSD symptoms. When the face and context matched, participants with higher levels of PTSD were significantly more accurate...

Stephen I Deutsch, C Teal Raffaele
Deficits in decoding and understanding facially expressed emotions occur commonly in persons with autism spectrum disorder (ASD), which contribute to the impairment of social communication that serves as one of its core diagnostic criteria. Research suggests that abnormalities of visual scanning of the face, activation of key nodes within the "social brain" by facially expressed emotions, functional connectivity within and between nodes of the "social brain", and transduction of specific neurotransmitter/neuromodulatory signals contribute to the pathogenesis of these deficits in at least some persons with ASD...

Facial form depends on the precise positioning of cartilage, bone, and tooth fields in the embryonic pharyngeal arches. How complex signaling information is integrated to specify these cell types remains a mystery. We find that modular expression of Forkhead-domain transcription factors (Fox) in the zebrafish face arises through integration of Hh, Fgf, Bmp, Edn1, and Jagged-Notch pathways. Whereas loss of C-class Fox proteins results in reduced upper facial cartilages, loss of F-class Fox proteins results in distal jaw truncations and absent midline cartilages and teeth...

Emotion can be conceptualized by the dimensional account of emotion with the dimensions of valence and arousal. There is little discussion of the difference in discriminability across the dimensions. The present study hypothesized that any pair of emotional expressions differing in the polarity of both valence and arousal dimensions would be easier to distinguish than a pair differing in only one dimension. The results indicate that the difference in the dimensions did not affect participants' reaction time...

Past attempts to characterize the neural mechanisms of affective priming have conceptualized it in terms of classic cognitive conflict, but have not examined the neural oscillatory mechanisms of subliminal affective priming. Using behavioral and electroencephalogram (EEG) time frequency (TF) analysis, the current study examines the oscillatory dynamics of unconsciously triggered conflict in an emotional facial expressions version of the masked affective priming task. The results demonstrate that the power dynamics of conflict are characterized by increased midfrontal theta activity and suppressed parieto-occipital alpha activity...

INTRODUCTION AND OBJECTIVES: Face recognition plays an important role in the field of biometrics, bioinformatics, and forensic identification. Human faces appear bilaterally symmetric. However, asymmetry is a norm in the human body and careful morphological and metric examination of the human face gives an exact idea of the asymmetry present in the face of an individual. Most of the studies on asymmetry of human face have been carried out with regard to evaluation of expressions in psychology, anthropology, and biometrics...

Humans express facial mimicry across a variety of actions. This article explores a distinct example, contagious yawning, and the links to empathy and prosocial behavior. Prior studies have suggested that there is a positive link between empathy and the susceptibility to contagious yawning. However, the existing evidence has been sparse and contradictory. We present results from 2 laboratory studies conducted with 171 (Study 1) and 333 (Study 2) student volunteers. Subjects were video-recorded while watching muted videos of individuals yawning, scratching, or laughing...

Although many sensory phenomena vary continuously, humans tend to divide them into discrete categories with facial expressions being divided into categories such as happy, sad, anger, and fear. A critical effect of category use is categorical perception: same sized physical differences are better perceived if the difference occurs between two categories rather than within the same category. Here we investigate the lateralization of categorical perception of facial expressions. Categorical perception of facial expressions may be lateralized to the right hemisphere due to the intimacy of basic, possibly universal and innate, prototypical facial expression categories and face processing which is predominantly lateralized to the right hemisphere...

There is considerable interest in understanding the emotional effects of alcohol. While a great deal of experimental research has focused on alcohol's ability to relieve negative emotions, there has been far less focus on the effects of alcohol on positive emotions. Further, the available research on positive emotion tends to test alcohol while participants are alone. Yet alcohol is often consumed in social settings, and enhancing social pleasure is consistently identified as being a primary motive for drinking...

People with mirror-touch synaesthesia (MTS) report tactile sensations on their own body when seeing another person being touched. Although this has been associated with heightened empathy and emotion perception, this finding has been disputed. Here, we conduct two experiments to explore this relationship further. In Experiment 1, we develop a new screening measure for MTS. We show that MTS is related to vicarious experiences more generally, but is not a simple exaggerated version of normality. For example, people with MTS report videos of scratching as "touch" rather than "itchiness" and have localized sensations when watching others in pain...

Infants from an early age have a bias to attend more to faces than non-faces and after 5 months are particularly attentive to fearful faces. We examined the specificity of this "fear bias" in 5-, 7-, and 12-month-old infants (N = 269) and 36-month-old children (N = 191) and whether its development is associated with features of the early rearing environment, specifically maternal anxiety and depression symptoms. Attention dwell times were assessed by measuring the latencies of gaze shifts from a stimulus at fixation to a new stimulus in the visual periphery...

The RAVDESS is a validated multimodal database of emotional speech and song. The database is gender balanced consisting of 24 professional actors, vocalizing lexically-matched statements in a neutral North American accent. Speech includes calm, happy, sad, angry, fearful, surprise, and disgust expressions, and song contains calm, happy, sad, angry, and fearful emotions. Each expression is produced at two levels of emotional intensity, with an additional neutral expression. All conditions are available in face-and-voice, face-only, and voice-only formats...

BACKGROUND/AIMS: The rejuvenation properties of nanofat grafting have been described in recent years. However, it is not clear whether the clinical efficacy of the procedure is attributable to stem cells or linked to other components of adipose tissue. In this study we isolated nanofat-derived stem cells (NFSCs) to observe their biological characteristics and evaluate the efficacy of precise intradermal injection of nanofat combined with platelet-rich fibrin (PRF) in patients undergoing facial rejuvenation treatment...

AIMS: To identify endogenous sources of glial cell line-derived neurotrophic factor (GDNF) at the injury site following inferior alveolar nerve transection (IANX) and to determine whether GDNF signaling promotes the recovery of orofacial pain sensation. METHODS: Nociceptive mechanical sensitivity of the facial skin was assessed following IANX (n = 10) or sham operation (n = 7). GDNF-positive cells were identified and the amount of GDNF measured in the injured region of IANX rats (n = 10) and in sham rats (n = 10)...

In order to assess how the perception of audible speech and facial expressions influence one another for the perception of emotions, and how this influence might change over the course of development, we conducted two cross-modal priming experiments with three age groups of children (6-, 9-, and 12-years old), as well as college-aged adults. In Experiment 1, 74 children and 24 adult participants were tasked with categorizing photographs of emotional faces as positive or negative as quickly as possible after being primed with emotion words presented via audio in valence-congruent and valence-incongruent trials...
