Facial expressions and affect

Huixia Zhou, Bibing Dai, Sonja Rossi, Juan Li
Background: Depressed populations demonstrate a greater tendency to have negative interpretations on ambiguous situations. Cognitive theories concerning depression proposed that such a negative bias plays an important role in developing and maintaining depression. There is now fairly consistent evidence arising from different stimuli and assessment methods that depression is featured by such a bias. The current study aimed to explore the neural signatures associated with the interpretation bias in the elderly with depressive symptoms confronted with different facial expressions using event-related brain potentials (ERPs)...

BACKGROUND: Hamm is an Arabic word that is used to express suffering. Idioms of distress are communicated differently in different contexts and cultures. Understanding idioms of distress and symptoms can help in diagnosis and lead to socioculturally sensitive health care. METHODS: In this qualitative study, we did semi-structured interviews with men and women of all age groups. Questions focused on the definition, causes, and consequences of Hamm. Responses were analysed by reading and re-reading interview transcripts until themes and subthemes emerged...

BACKGROUND: Deficits in emotional prosody processing have been observed in bipolar disorder (BD). While recent neural studies have explored impaired processing of facial expressions, little is known about deficits in emotional speech processing, or the specific stages of processing at which they occur. This study examined if pre-attentive detection and attention to emotional speech is impaired in BD, relative to healthy individuals. METHODS: The EEG data was collected from 14 individuals with BD and 14 healthy control (HC) participants while the auditory stimuli was presented via a passive three-stimulus oddball sequence which included emotionally (neutral, happy, sad) spoken syllables and acoustically matched nonvocal tones...

The μ-opioid system modulates responses to pain and psychosocial stress and mediates non-social and social reward. In humans, the μ-opioid agonist morphine can increase overt attention to the eye-region and visual exploration of faces with neutral expressions. However, little is known about how the human μ-opioid system influences sensitivity to and appraisal of subtle and explicit cues of social threats and reward. Here, we examined the effects of selective μ-opioid stimulation on perception of anger and happiness in faces with explicit, neutral or implicit emotion expressions...

The recognition of emotional facial expressions is often subject to contextual influence, particularly when the face and the context convey similar emotions. We investigated whether spontaneous, incidental affective theory of mind inferences made while reading vignettes describing social situations would produce context effects on the identification of same-valenced emotions (Experiment 1) as well as differently-valenced emotions (Experiment 2) conveyed by subsequently presented faces. Crucially, we found an effect of context on reaction times in both experiments while, in line with previous work, we found evidence for a context effect on accuracy only in Experiment 1...

Rosacea is a common facial skin disorder affecting middle-aged adults. Its aetiology is unknown and pathogenesis uncertain. Activation of the host innate immune response has been identified as important. The Demodex mite population in the skin of these patients is significantly higher than in subjects with normal skin suggesting they may be of etiological importance in this disorder. Little is known of the role of these mites in human skin and their potential to interact with the host immune system has not been elucidated...

Adolescence is a time of increased social-affective sensitivity, which is often related to heightened health-risk behaviors. However, moderate levels of social sensitivity, relative to either low (social vacuum) or high levels (exceptionally attuned), may confer benefits as it facilitates effective navigation of the social world. The present fMRI study tested a curvilinear relationship between social sensitivity and adaptive decision-making. Participants (ages 12-16; N = 35) played the Social Analogue Risk Task (SART), which measures participants' willingness to knock on doors in order to earn points...

People with schizophrenia show marked reductions in their emotional expressiveness, generally known as blunted affect. In this study, we tested whether interaction partners would evaluate community-dwelling participants with schizophrenia less favorably than healthy controls and whether this difference would be explained by reduced smiling behavior related to schizophrenia. We also tested whether deficient affect recognition would predict reduced smiling. We created 3 study groups, consisting of 28 participants each, participants with schizophrenia (SZ), healthy controls (HC), and naive healthy interaction partners (IP)...

Interoception describes the mapping of the body's internal landscape and has been connected to greater intensity of emotional experience. The goal of the current study was to explore the relationship between interoception and emotion face recognition in healthy adolescents. The heartbeat perception task was used to assess interoceptive accuracy(IAC) and participants were asked to recognize different facial expressions. EEG activity was recorded, providing data for the P100, the N170 and the P300 ERP components...

RSRC1, whose polymorphism is associated with altered brain function in schizophrenia, is a member of the serine and arginine rich-related protein family. Through homozygosity mapping and whole exome sequencing we show that RSRC1 mutation causes an autosomal recessive syndrome of intellectual disability, aberrant behaviour, hypotonia and mild facial dysmorphism with normal brain MRI. Further, we show that RSRC1 is ubiquitously expressed, and that the RSRC1 mutation triggers nonsense-mediated mRNA decay of the RSRC1 transcript in patients' fibroblasts...

During face perception, we integrate facial expression and eye gaze to take advantage of their shared signals. For example, fear with averted gaze provides a congruent avoidance cue, signaling both threat presence and its location, whereas fear with direct gaze sends an incongruent cue, leaving threat location ambiguous. It has been proposed that the processing of different combinations of threat cues is mediated by dual processing routes: reflexive processing via magnocellular (M) pathway and reflective processing via parvocellular (P) pathway...

It is yet unclear whether congenitally deaf cochlear implant (CD CI) users' visual and multisensory emotion perception is influenced by their history in sign language acquisition. We hypothesized that early-signing CD CI users, relative to late-signing CD CI users and hearing, non-signing controls, show better facial expression recognition and rely more on the facial cues of audio-visual emotional stimuli. Two groups of young adult CD CI users-early signers (ES CI users; n = 11) and late signers (LS CI users; n = 10)-and a group of hearing, non-signing, age-matched controls (n = 12) performed an emotion recognition task with auditory, visual, and cross-modal emotionally congruent and incongruent speech stimuli...

INTRODUCTION: It is well established that depressive disorders are associated with abnormalities in the processing of affective information. However, type of stimuli, perceptual complexity and cognitive demand are important factors in evaluating these findings. In particular, processing mechanisms of perceptual boundaries in ecologically valid face stimuli are largely unknown in depression. METHODS: In the current study, intensity-ordered frame sequences provided a dynamic visualisation of happy or sad facial expressions fading from or to neutral expressions...

BACKGROUND: Abnormalities in affective cognition are putative endophenotypes for bipolar and unipolar disorders but it is unclear whether some abnormalities are disorder-specific. We therefore investigated affective cognition in monozygotic twins at familial risk of bipolar disorder relative to those at risk of unipolar disorder and to low-risk twins. METHODS: Seventy monozygotic twins with a co-twin history of bipolar disorder (n = 11), of unipolar disorder (n = 38) or without co-twin history of affective disorder (n = 21) were included...

Parkinson's disease is a neurodegenerative disorder classically characterized by motor symptoms. Among them, hypomimia affects facial expressiveness and social communication and has a highly negative impact on patients' and relatives' quality of life. Patients also frequently experience nonmotor symptoms, including emotional-processing impairments, leading to difficulty in recognizing emotions from faces. Aside from its theoretical importance, understanding the disruption of facial emotion recognition in PD is crucial for improving quality of life for both patients and caregivers, as this impairment is associated with heightened interpersonal difficulties...

OBJECTIVE: Previous studies investigating the effects of skin surface topography and colouration cues on perception of female faces reported a differential weighting for perception of skin topography and colour evenness, where topography was a stronger visual cue for perception of age, whereas skin colour evenness was a stronger visual cue for perception of health. We extend these findings in a study of the effect of skin surface topography and colour evenness cues on perceptions of facial age, health, and attractiveness in males...

Orofaciodigital syndrome (OFD) is a group of hereditary disorders identified by malformations of the mouth (oris), face (facies), hands and feet (digitus=finger and toe). Although there are several different types reported in the literature, there is a great overlap in their clinical presentation. The full spectrum of all disorders due to OFD is not yet fully understood, since each patient shows variations in the expression of the syndrome. In the oral cavity, teeth are often affected by various alterations, such as dental caries, abnormal teeth, enamel hypoplasia, supernumerary teeth and dental agenesis...

Ryanodine receptor 1 ( RYR1 ) is an intracellular calcium receptor primarily expressed in skeletal muscle with a role in excitation contraction. Both dominant and recessive mutations in the RYR1 gene cause a range of RYR1 -related myopathies and/or susceptibility to malignant hyperthermia (MH). Recently, an atypical manifestation of ptosis, variably presenting with ophthalmoplegia, facial paralysis, and scoliosis but without significant muscle weakness, has been reported in 9 cases from 4 families with bialleic variants in RYR1 ...

The current research was designed to assess possible differences in the emotional content of pleasant and unpleasant face emoji using acoustically evoked eyeblink startle reflex response. Stimuli were selected from Emojipedia Webpage. First, we assessed these stimuli with a previous independent sample of 190 undergraduate students (46 males and 144 females) mean age of 21.43 years (SD 3.89). A principal axis method was performed using the 30 selected emoji faces, extracting two factors (15 pleasant and 15 unpleasant emoji)...

Sleep and circadian rhythmicity both play an important role in human's cognitive functioning, yet the way in which early development of sleep and circadian rhythm affects cognitive processes and social learning in infants remains less understood. We examined the association of sleep and circadian activity rhythm (CAR) with face and emotional information processing in 12-month old infants. Face processing was measured by eye tracking, whereby infants' scanning patterns and pupil dilations were calculated when they were presented with neutral, pleasant and unpleasant faces...
