About this Research Topic

Background

Faces and body parts/actions convey valuable information for detecting and identifying conspecifics and discerning their identity, age, sex, attractiveness, emotion, attention, and intentions. This visual information triggers specific behavioral and cognitive responses, both conscious and unconscious, that affect social non-verbal communication and interaction in humans. The ability to interpret facial and bodily cues is not unique to humans; various species, spanning both vertebrates and invertebrates, share this ability to some extent. Social information influences effective interactions between individuals and plays a critical role in survival. In both the human and non-human primate brain, networks of regions in the cortical and subcortical areas are involved in the processing of facial features and body parts/actions. Potential homologs exist in the so-called Neural Social Network of other vertebrates. A comprehensive understanding of the neural computation within each area and across areas requires further exploration. Additionally, it remains unclear to what extent the neural substrate and computation are shared across phylogeny.

The perceptual abilities related to face and body parts/actions recognition have been investigated across diverse research domains, encompassing neuroscience, clinical neurology, psychology, ethology, primatology, artificial intelligence, and cognitive robotics. Despite substantial insights into the psychological/behavioral aspects of these abilities, as well as an understanding of the underlying neural substrates gained from prior studies, we still find ourselves at an early stage of comprehending the computational properties of the processing of the neural systems. For example, uncertainties persist regarding the exact differences in face processing between the cortical and subcortical pathways. The functional and organizational relationship between the face processing system and the body part/action processing system also remains unclear. Additionally, to what extent the computational properties are shared by different animal species is yet to be determined. Addressing these questions not only advances our understanding of the neural mechanisms of face and body parts/actions recognition but also contributes to unraveling the deficiency of certain developmental and psychiatric disorders. The objective of this Research Topic is to provide a platform by bringing together articles on the processing of faces, body parts/actions, and other animacy cues such as biological motion.

We anticipate that the articles address the computational properties of neural processing of face, body parts/actions, or other animacy cues. These articles may encompass studies involving humans, animals, and even deep convolutional neural networks or robots, as long as they are relevant to the exploration of biological neural systems. While we anticipate a primary focus on empirical research papers, we also welcome theoretical analyses and critical reviews of previous work.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
