Abstract： Facial expressions are emotional signals conveyed through muscle movements, such as those in the eyes and mouth. Facial emotion recognition plays a crucial role in infant's social and communicative development. The development of basic facial expression recognition in infants is asynchronous: the recognition of positive expressions occurs earlier than that of negative expressions, and the development of emotion perception is earlier than emotion understanding.Infants recognize positive facial expressions earlier than negative ones. They can distinguish happy expressions when they are 2 months old, and negative expressions when they are 4-6 months old. Infant's ability to perceive emotions develops earlier than their ability to understand emotions. The 7-month-old infant has initially possessed the emotion perception ability. They can not only distinguish the basic facial expressions, but also form a classification perception and master the visual observation strategy similar to that of adults. The development of emotional understanding is relatively lagging behind, and 12-month-old infants cannot accurately understand the emotional meaning conveyed by different the negative valence expressions. Infants' basic facial expression recognition undergoes a shift from positive bias to negative bias. In the first half of infancy, infants show an attentional bias to happy expressions, and from 5 months onwards, infants show an attentional bias to fearful expressions. The development of infant's ability to recognize basic facial expression recognition reflects the process from the activation of basic emotions to the formation of emotional schemas. Basic expressions are a preset system that humans evolved to adapt to the environment, and infants are born with the innate ability to express and recognize them. Once basic emotions are activated by the environment, infants acquire corresponding recognition abilites. Emotional schemas are acquired through postnatal development, and are the result of the dynamic interaction process between emotions and cognition. Both individual cognitive development and environmental stimuli play important roles in the formation of emotional schemas. The experience-expectant mechanism in the human brain enables infants to recognize positive expressions earlier than negative expressions, which helps infants to receive more feedback from adults. From the second half of infancy, infants may develop an attentional bias towards negative expression, which can aid in their better understanding of others's feelings. There may also be a sensitive period during the second half of infancy for the development of the ability to recognize negative emotions. Moreover, the experience-dependent mechanism in the brain determines the plasticity of the brain's emotional neural network. The mother-infant relationship, family, social environment, race, and culture all can affect the development of an infant's ability to recognize facial expressions.

Abstract： “Sense of agency” refers to the sense of controlling one’s actions and the course of events in the outside world. It is based on the match between the expected action and the real sensory feedback. The first part of this article introduces a method for implicit measurement of sense of agency. The second part deals with the factors that influence the sense of agency from the aspects of intentionality and sensory feedback. Part three provides the conclusion. With an emphasis on the functions of the prefrontal and parietal lobes, this article provides evidence to explain the mechanism of sense of agency through the theoretical model and cognitive neuroscience.

Abstract： Sense of agency (SOA) refers to the feeling of controlling one's own actions and events in the external world through voluntary actions. Over the past two decades, SOA has increasingly attracted attention from researchers, and its cognitive neural mechanism is still a cutting-edge scientific problem in this field. There are two ways to measure SOA: explicit measurement (i.e., the explicit judgements of agency reported by individuals) and implicit measurement (i.e., sensory perception difference). Both the temporal binding effect and the sensory attenuation effect can be used as implicit measures for SOA. Intention of action and sensory feedback are two core components constituting the SOA. Intention of action is a conscious experience of determining or planning to initiate an action. Extinction and termination of intention can prospectively affect SOA. The valence of action outcome, the causal relationship between an action and its outcome, and the characteristics of the outcome may retrospectively affect the sense of agency. According to the Comparator Model, a copy of the action command contained in the subjective intention predicts the outcome before action. When comparing the predicted sensory outcome with the actual feedback of the action, the prediction error is zero, generating SOA. Evidence from cognitive neuroscience suggests that intention may be closely related to the activities in the supplementary and pre-supplementary motor areas, and the action outcome may be related to the activities of the posterior parietal cortex. This project will focus on the neural substrates underlying SOA, and explore the prospective way of intention and the retrospective way of outcome exerting on SOA by manipulating different attributes of two core components (i.e., subjective intention and action outcome). The magnetoencephalography technology, which is of high temporal and spatial resolution, is employed to extract the time-space characteristics of SOA at the fronto-parietal network in both the time windows of action-outcome and after-outcome. Elucidating the neural mechanism of SOA will contribute to our understanding of the generation and aftereffects of human actions, thus providing implications for demarcating behavioral responsibilities in moral and legal settings, and for diagnosing related mental diseases.

Abstract： Sense of agency (SoA) refers to the feeling of controlling one's own actions and, through them, events in the external world when performing voluntary actions. Intention of action and sensory feedback are two core components that constitute the sense of agency. However, the cognitive neural mechanism underlying the influence of these two components on SoA is unclear. We propose to explore the feedforward effect of action intention and the feedback effect of sensory feedback on SoA. The magnetoencephalography technology, which is of high temporal and spatial resolution, is employed to extract the time-space characteristics of sense of agency at the fronto-parietal network in both the time windows of action-outcome and after-outcome. The elucidation of this cognitive neural mechanism of SoA will contribute to our understanding of the generation and aftereffects of human actions; furthermore, it will provide implications for the demarcation of behavioral responsibilities in moral and legal settings, and for the clinical diagnoses of related mental diseases.

Abstract： The sense of agency is the experience of controlling one's own motor acts and, through these acts, controlling the course of external events in the interaction with the environment. It can be extended to the actions of other agents and the outcomes caused by their actions in social interaction. A large number of studies in the context of social interaction have shown that the sense of agency is influenced by social interaction situations such as observation, competition, cooperation and hierarchical interaction. Relevant neural mechanism studies have demonstrated that the fronto-parietal network, including primary motor cortex, angular gyrus, insula, temporo-parietal junction, medial prefrontal cortex, and precuneus, plays an important role in the sense of agency in social interaction. Future researches need to further explore the cognitive and neural mechanisms underlying the effects of social interaction situations on sense of agency, investigate the influences of multimodal stimuli on sense of agency in social interaction, and consider the modulation effects of sense of agency on cognitive processes and behavioral responses in social interaction.
