Pair Bond-Induced Affiliation and Aggression in Male Prairie Voles Elicit Distinct Functional Connectivity in the Social Decision-Making Network

Complex social behaviors are governed by a neural network theorized to be the social decision-making network (SDMN). However, this theoretical network is not tested on functional grounds. Here, we assess the organization of regions in the SDMN using c-Fos, to generate functional connectivity models during specific social interactions in a socially monogamous rodent, the prairie voles (Microtus ochrogaster). Male voles displayed robust selective affiliation toward a female partner, while exhibiting increased threatening, vigilant, and physically aggressive behaviors toward novel males and females. These social interactions increased c-Fos levels in eight of the thirteen brain regions of the SDMN. Each social encounter generated a distinct correlation pattern between individual brain regions. Thus, hierarchical clustering was used to characterize interrelated regions with similar c-Fos activity resulting in discrete network modules. Functional connectivity maps were constructed to emulate the network dynamics resulting from each social encounter. Our partner functional connectivity network presents similarities to the theoretical SDMN model, along with connections in the network that have been implicated in partner-directed affiliation. However, both stranger female and male networks exhibited distinct architecture from one another and the SDMN. Further, the stranger-evoked networks demonstrated connections associated with threat, physical aggression, and other aversive behaviors. Together, this indicates that distinct patterns of functional connectivity in the SDMN can be detected during select social encounters.

An Evaluation of Human Conversational Preferences in Social Human-Robot Interaction

To generate context-aware behaviors in robots, robots are required to have a careful evaluation of its encounters with humans. Unwrapping emotional hints in observable cues in an encounter will improve a robot’s etiquettes in a social encounter. This article presents an extended human study conducted to examine how several factors in an encounter influence a person’s preferences upon an interaction at a particular moment. We analyzed the nature of conversation preferred by a user considering the type of conversation a robot could have with its user, having the interaction initiated by the robot itself. We took an effort to explore how such preferences differ as the factors present in the surrounding alter. A social robot equipped with the capability to initiate a conversation is deployed to conduct the study by means of a wizard-of-oz (WoZ) experiment. During this study, conversational preferences of users could vary from “no interaction at all” to a “long conversation.” We changed three factors in an encounter which can be different from each other in each circumstance: the audience or outsiders in the environment, user’s task, and the domestic area in which the interaction takes place. Conversational preferences of users within the abovementioned conditions were analyzed in a later stage, and critical observations are highlighted. Finally, implications that could be helpful in shaping future social human-robot encounters were derived from the analysis of the results.

Observations on Death and Life of Public Space in Australia during the COVID-19 Pandemic

“Do not touch me, touch and deal with other people in the spirit of love” is stated upfront in Zizek (2020) recent reflection on the unprecedented global pandemic that has a firm grip on our societies. The quote makes two strong points that highlight the essence of this commentary. First, it implies that during the global COVID19 pandemic each and every one of use is forced to deal with their on human spirit embodied through the ontological state of existence and apply mindfulness and accountability for their actions in their everyday life routines. Second, public life in cities is different. Quickly the ‘new normal’ dictates our everyday life routines while systemic spatial issues being amplified, while social distancing measures are in place and restriction on social encounter being enforced. We present an argument that is based on direct observations of lockdown conditions during the first wave in 2020 in the Australian context. Careful framing around the concepts of ‘urban loveability’ and public space allows us to critically examine the synergy between aspects of the human spirit that celebrate and unite us. Whether the ‘new normal’ embraces death or life is evident if we pay attention to detailed traces of dynamic and intangible elements in public spaces. They remind us what makes us human and holding the possibility to realise a new ontological state of existence.

Conversations on the Frontier: Finding the Dialogic in Nineteenth-century Anthropological Archives

While anthropological archives tend to be named after the collector of the material, they are often the product of conversations and long-term engagements with informants. Focusing on the concept of the dialogic, this article contends that these materials ought to be equally conceived as co-productions, often made via complex, asymmetrical researcher/researched engagements. We specifically home in on the dialogic traces left in the archive of the nineteenth century Australian ethnographer A. W. Howitt and his various conversations with an Aboriginal man named Ienbin. We argue that by being attentive to the dialogic aspects of ethnographic sources we can recognize that the Indigenous or anthropological knowledge contained within them is to a significant degree co-constructed in as much as it emerges from social encounter and interaction. More than merely acknowledging the agency of Indigenous informants we propose a more dynamic reading of these texts as products of discursive interactions and shifting relationships.
