Abstract： The studies for body recognition processing often focus on inverted body. And the body inversion effect refers to the fact that the reaction time to identify the inverted body is longer and the correct rate is lower than that to the upright body. Recently, researchers have used a variety of techniques to examine the effect and its configural processing mechanism, in which there are still controversy about the role of head information. In addition, now available body inversion effect mainly concentrated on the configural processing theory and the configural processing continuum theory, however there are still some discrepancies between the two theories in terms of the subcomponents involved in the configural processing. Further researches, with more special populations involved, can focus on the improvements of relevant theories and the specific role of head information, through using materials of high ecological validity.

Abstract： The human parental brain could be defined as is the network of regions that support caregiving behaviors to identify and react to infant related stimuli (infant vocals and facial expressions). First, we reviewed the neural circuits that were demonstrated to be involved in establishing and maintaining parent-infant relationships, which included circuits for motivation-reward, empathy, emotion regulation and executive function. And the important brain areas incorporate the orbitofrontal cortex, anterior cingulate cortex, anterior insula, amygdala, and supplementary motor area. Second, the current review summed that human parental brain is sensitive to multiple parenting determinants, including parenting abilities, parental hormones and psychopathology. The growth of parenting abilities and the improvement of oxytocin levels are beneficial to the processing for infant stimuli. Finally, several advices were proposed for future directions: 1) prospective and longitudinal studies across important transition periods for parenting; 2) describing the neural basis of male psychopathologies and exploring targeted interventions and treatments; 3) employing some advanced neuroscience technique (e.g., hyper scanning) to highlight the simultaneous neural activity between mother and father or parents and infants; and 4) conducting parental brain research in Chinese culture.

Abstract： The integration of various emotional information from different modalities (e.g., face and voice) plays an important role in our interpersonal communication. In order to understand its brain mechanism, more and more researchers found that the interaction between facial expression and vocal emotional information begins in the early stage of perception, and the integration of emotional information content occurs in the late decision-making stage. In the early stage, the primary sensory cortex is responsible for encoding information; while in the late stage, the amygdala, temporal lobe and other advanced brain regions are responsible for cognitive evaluation. In addition, the functional coupling of oscillation activities on multiple frequency bands facilitates the integration of emotional information cross channels. Future research needs to explore whether facial expression and vocal emotional information integration is associated with emotional conflict, and whether inconsistent emotional information has advantages. Lastly, we should find out how the neural oscillations of different frequency bands promotes the integration of facial expression and vocal emotional information, so as to further understand its dynamic basis.

Abstract： The body contains rich social information. Studying the body representation’s development in the early stage is significant for revealing body representation’s specific mechanism and further understanding the infants’ social development. Through looking at the theories about the body shape and the body movement, we summarize the representation patterns of the infant’s body structure information and movement information. At the same time, the article describes two theories on the infant's body representation development. Future researches should pay more attention to explain the specific development process and the controversial critical period of body representation in fancy. Moreover, the mechanism of biological motion preference on body representation should be explored through using the brain imaging technology.
