Expression Perception

Emotions are expressed by the face, the voice and the whole body. Research on the face and the voice has not only demonstrated that emotions are perceived categorically, but that this perception can be manipulated. The purpose of this study was to investigate, via two separate experiments using adaptation and multisensory techniques, whether the perception of body emotion expressions also shows categorical effects and plasticity. We used an approach known from studies investigating both face and voice emotion perception and created novel morphed affective body stimuli, which varied in small incremental steps between emotions. Participants were instructed to perform an emotion categorisation on these morphed bodies after adaptation to bodies conveying different expressions (Experiment 1), or while simultaneously hearing affective voices (Experiment 2). We show that not only is body expression perceived categorically, but that both adaptation to affective body expressions and concurrent presentation of vocal affective information can shift the categorical boundary between body expressions specifically for the angry body expressions. Overall, our findings provide significant new insights into emotional body categorisation, which may prove important into gaining a deeper understanding of body expression perception in everyday social situations.

AbstractEmotion perception from facial and vocal expressions is a multisensory process critical for human social interaction. When asked to judge emotions by attending to either face or voice, the accuracy was higher when facial expressions are congruent with vocal expressions than when they are incongruent. This congruency effect was shown to be affected by cultural background. Here we conducted functional MRI alongside a multisensory emotion perception task involving Japanese and Dutch participants. They were presented with movies in which congruent or incongruent emotions were expressed through faces and voices. The participants were asked to judge the emotion of either the face or the voice. Consistent with previous studies, behavioral results showed an interaction between group and task. fMRI results revealed that during voice-based judgement, congruency effects of the primary visual cortex, by means of the task related activity of congruent stimuli subtracted by that of incongruent stimuli, were more prominent in the Dutch group than in Japanese group. Finally, behavioral and neural congruency effects of the primary visual cortex were positively correlated only in the Dutch group. Taken together, our results show that culture affects the activities of early sensory areas in multisensory perception from facial and vocal expressions.

While the cognitive disturbances that frequently follow severe traumatic brain injury (TBI) are relatively well understood, the ways in which these affect the psychosocial functioning of people with TBI are yet to be determined and have thus received little attention in treatment research. Growing evidence indicates that a significant proportion of individuals with TBI demonstrate an inability to recognize affective information from the face, voice, bodily movement, and posture. Because accurate interpretation of emotion in others is critical for the successful negotiation of social interactions, effective treatments are necessary. Until recently, however, there have been no rehabilitation efforts in this area. The present review examines the literature on emotion perception deficits in TBI and presents a theoretical rationale for targeted intervention. Several lines of research relevant to the remediation of emotion perception in people with TBI are considered. These include work on emotion perception remediation with other cognitively impaired populations, current neuropsychological models of emotion perception and underlying neural systems, and recent conceptualizations of remediation processes. The article concludes with a discussion of the importance of carrying out efforts to improve emotion perception within a contextualized framework in which the day-to-day relevance of training is clear to all recipients.

IntroductionCommunication today is increasingly seen as a process through whichthe exchange and sharing of meaning is made possible. Commtinication asa subject of scientific inquiry is not unique to the field of mass communication.Mathematicians, engineers, sociologists, psychologists, political scientists,anthropologists, and speech communicators have been taking an interest inthe study of communication. This is not surprising because communicationis the basic social process of human beings. Although communication hasgrown into a well developed field of study, Muslim scholars have rdrely hcusedon the study of communication. Thus, a brief introduction to the widely usedcommunication concepts and a framework for the study of communicationwithin the context of this paper is provided.In 1909, Charles Cooley defined communication from a sociologicalperspective as:The mechanism through which human relations exist and develop -all the symbols of mind, together with the means of conveyingthem through space and preserving them in time. It includes theexpression of the face, attitude and gesture, the tones of the voice,words, writing, printing, railways, telegraph, and whatever elsemay be the latest achievement in the conquest of space and time.In 1949, two engineers, Claude Shannon and Warren Weaver, definedcommunication in a broader sense to include all procedures:By which one mind may affect another. This, of course, involvesnot only written and oral speeches, but also music, the pictorialarts, the theater, the ballet, and, in kct, all human behavior.Harold Lasswell, a political scientist, defines communication simply as:A convenient way to describe the act of communication is to answerthe following question: Who, says what, in which channel, towhom, with what effect?S.S. Stevens, a behavioral psychologist, defines the act of communication as:Communication occurs when some environmental disturbance (thestimulus) impinges on an organism and the organism doessomething about it (makes a discriminatory response) . . . Themessage that gets no response is not a commnication.Social psychologist Theodore Newcomb assumes that:In any communication situation, at least two persons will becommunicating about a common object or topic. A major functionof communication is to enable them to maintain simultaneousorientation toward one another and toward the common object ofcommunication.Wilbur Schramm, a pioneer in American mass communication research,provides this definition:When we communicate we are trying to share information, anidea, or an attitude. Communication always requires threeelements-the source, the message, and the destination (thereceiver).

In March 1943, having narrowly escaped Europe three years earlier, Abraham Joshua Heschel published “The Meaning of This War,” his first essay in an American publication. The essay shows, quite remarkably, his full command of literary English. It also shows, as biographer Edward Kaplan remarks, that Heschel “had found his militant voice.” “Emblazoned over the gates of the world in which we live,” the essay begins, “is the escutcheon of the demons. The mark of Cain in the face of man has come to overshadow the likeness of God. There have never been so much guilt and distress, agony and terror. At no time has the earth been so soaked with blood.” Heschel's extraordinary life's witness, his whole body of work, traverses precisely this anthropological and theological knife's edge: The mark of Cain in the face of man has come to overshadow the likeness of God. Where is God? Or better, Who is God? in relation to the rapacious misuse and idolatrous distortion of human freedom? Or simply, Is God?

Aim of the research The literature on emotion recognition from facial expressions shows significant differences in recognition ability depending on the proposed stimulus. Indeed, affective information is not distributed uniformly in the face and recent studies showed the importance of the mouth and the eye regions for a correct recognition. However, previous studies used mainly facial expressions presented frontally and studies which used facial expressions in profile view used a between-subjects design or children faces as stimuli. The present research aims to investigate differences in emotion recognition between faces presented in frontal and in profile views by using a within subjects experimental design. Method The sample comprised 132 Italian university students (88 female, Mage = 24.27 years, SD = 5.89). Face stimuli displayed both frontally and in profile were selected from the KDEF set. Two emotion-specific recognition accuracy scores, viz., frontal and in profile, were computed from the average of correct responses for each emotional expression. In addition, viewing times and response times (RT) were registered. Results Frontally presented facial expressions of fear, anger, and sadness were significantly better recognized than facial expressions of the same emotions in profile while no differences were found in the recognition of the other emotions. Longer viewing times were also found when faces expressing fear and anger were presented in profile. In the present study, an impairment in recognition accuracy was observed only for those emotions which rely mostly on the eye regions.

Background: While increased face mask use has helped reduce COVID-19 transmission, there have been concerns about its influence on thermoregulation during exercise in the heat, but consistent, evidence-based recommendations are lacking. Hypothesis: No physiological differences would exist during low-to-moderate exercise intensity in the heat between trials with and without face masks, but perceptual sensations could vary. Study Design: Crossover study. Level of Evidence: Level 2. Methods: Twelve physically active participants (8 male, 4 female; age = 24 ± 3 years) completed 4 face mask trials and 1 control trial (no mask) in the heat (32.3°C ± 0.04°C; 54.4% ± 0.7% relative humidity [RH]). The protocol was 60 minutes of walking and jogging between 35% and 60% of relative VO2max. Rectal temperature (Trec), heart rate (HR), temperature and humidity inside and outside of the face mask (Tmicro_in, Tmicro_out, RHmicro_in, RHmicro_out) and perceptual variables (rating of perceived exertion (RPE), thermal sensation, thirst sensation, fatigue level, and overall breathing discomfort) were monitored throughout all trials. Results: Mean Trec and HR increased at 30- and 60-minute time points compared with 0-minute time points, but no difference existed between face mask trials and control trials ( P > 0.05). Mean Tmicro_in, RHmicro_in, and humidity difference inside and outside of the face mask (ΔRHmicro) were significantly different between face mask trials ( P < 0.05). There was no significant difference in perceptual variables between face mask trials and control trials ( P > 0.05), except overall breathing discomfort ( P < 0.01). Higher RHmicro_in, RPE, and thermal sensation significantly predicted higher overall breathing discomfort ( r2 = 0.418; P < 0.01). Conclusion: Face mask use during 60 minutes of low-to-moderate exercise intensity in the heat did not significantly affect Trec or HR. Although face mask use may affect overall breathing discomfort due to the changes in the face mask microenvironment, face mask use itself did not cause an increase in whole body thermal stress. Clinical Relevance: Face mask use is feasible and safe during exercise in the heat, at low-to-moderate exercise intensities, for physically active, healthy individuals.

No book was more sought after by families in the early decades of our country than Buchan's Domestic Medicine, which was first published in England in 1769 and passed through 19 editions during the following 50 years. Buchan described the signs, symptoms and treatment of children with croup as follows: Children are often seized very suddenly with this disease, which, if not quickly relieved, proves mortal. . . . This disease generally prevails in cold and wet seasons. It is most common upon the seacoast, and in low marshy countries. Children of a gross and lax habit are most liable to it. . . . It generally attacks children in the night, after having been much exposed to damp cold easterly winds through the day. Damp houses, wet feet, thin shoes, wet clothes, or any thing that obstructs the perspiration, may occasion the croup. It is attended with a frequent pulse, quick and laborious breathing, which is performed with a peculiar kind of croaking noise, that must be heard at a considerable distance. The voice is sharp and shrill, and the face is generally much flushed, though sometimes it is of a livid colour. When a child is seized with the above symptoms, his feet should be immediately put into warm water. He ought likewise to be bled, and to have a laxative clyster administered as soon as possible. He should be made to breathe over the steams of warm water and vinegar; or an emollient decoction, and emollient cataplasms or fomentations may be applied round his neck.

Tlr4 Activation

Diabetes mellitus is an epidemic disease characterized by alterations in glucose transport, which is tightly regulated by a family of specialized proteins called the glucose transporters (GLUTs). Although diabetic cardiomyopathy is a common complication in diabetic patients, its pathogenesis is still not well understood. Toll-like receptor (TLR) 4, which plays a central role in pathogen recognition by the innate immune system, may also play a critical role in linking inflammation and metabolic disease. We hypothesized that TLR4 activation triggers cardiac insulin resistance. We used mice with a loss-of function mutation in TLR4 (C3H/HeJ) and age-matched wild-type (WT, C57BL/6N) mice (n=8/group) to investigate how feeding a high-fat diet (HFD, 60% kcal from fat) for 16 weeks affected whole-body and cardiac glucose metabolism. After 16 weeks, WT mice fed a HFD were obese and developed hyperglycemia and insulin resistance compared to WT mice on a control diet (10% kcal from fat). The C3H/HeJ mice were partially protected against HFD-induced obesity and insulin resistance. In the heart, WT mice fed a HFD had a 30% decrease (P<0.05) in GLUT4 protein content as measured by Western Blot of cardiac crude membrane protein extracts. In contrast, the loss-of-function point mutation in TLR4 partially rescued cardiac GLUT4 content in the face of a HFD. Interestingly, there was a 40% increase (P<0.05) in the novel GLUT isoform, GLUT8, in the heart when mice of either genotype were fed a HFD. Additionally, GLUT4 protein content was negatively (P<0.05) correlated with GLUT8 content in the myocardium, suggesting that GLUT8 may act as a compensatory mechanism in the face of HFD-induced GLUT4 downregulation. Phosphorylated Akt, a key protein of the insulin signaling pathway, was positively (P<0.05) correlated with GLUT4 content, while the basal/inactive form was negatively correlated. In conclusion, these data suggest that activation of TLR4 activation during diabetes and obesity alters glucose transport by an Akt mechanism, and as such is a pathogenic factor during peripheral and cardiac insulin resistance. Overall, TLR4 appears to be a key modulator in the cross-talk between inflammatory and metabolic pathways, as well as a potential therapeutic target for diabetes.
