The role of self–other distinction in understanding others' mental and emotional states: neurocognitive mechanisms in children and adults

Social interactions come with the fundamental problem of trying to understand others'' mental and affective states while under the overpowering influence of one''s own concurrent thoughts and feelings. The ability to distinguish between simultaneous representations of others'' current experiences as well as our own is crucial to navigate our complex social environments successfully. The developmental building blocks of this ability and how this is given rise to by functional and structural brain development remains poorly understood. In this review, I outline some of the key findings on the role of self–other distinction in understanding others'' mental as well as emotional states in children and adults. I will begin by clarifying the crucial role for self–other distinction in avoiding egocentric attributions of one''s own cognitive as well as affective states to others in adults and outline the underlying neural circuitry in overcoming such egocentricity. This will provide the basis for a discussion of the emergence of self–other distinction in early childhood as well as developmental changes therein throughout childhood and into adulthood. I will demonstrate that self–other distinction of cognitive and emotional states is already dissociable early in development. Concomitantly, I will show that processes of self–other distinction in cognitive and affective domains rely on adjacent but distinct neural circuitry each with unique connectivity profiles, presumably related to the nature of the distinction that needs to be made.     

HIV,Embodied Secrets,and Intimate Labour in Northern Nigeria

ABSTRACT

This article explores how HIV-positive women manage secrets through the use of their bodies. Women conspicuously enhance their beauty in an attempt to defend themselves against the violence of social exclusion. Moreover, they do so in order to forge safe, loving, and prosperous relationships with their boyfriends, husbands, and families. My goal is to understand how intimacy, as a material, affective, psychological, and embodied state, characterises these women's corporeal and sartorial acts. Further, I question how these embodied practices become imbricated in exchange relations with family members, health workers, and the larger community. To describe these routinised toils and triumphs as women seek to care for themselves and others, I employ the term ‘intimate labour’. I demonstrate how women gain access to social and economic resources by attending to and capitalising on the sensual and bodily desires and needs of others.     

Opportunity or Orientation? Who Uses Urban Parks and Why

There is growing recognition that interactions with nature provide many desirable human well-being outcomes, yet increasing urbanization is degrading the quality and quantity of nature experiences. Thus, it has become increasingly important to understand how and why urban dwellers interact with nature. Studies of urban green space use have largely focused on the availability and ease of access to green space, suggesting that greater opportunities to experience such space will lead to increased use. However, a growing literature emphasizes the potential for an individual''s nature orientation to affect their interaction with green space. Here we measure the importance of both opportunity and orientation factors in explaining urban park use. An urban lifestyle survey was deployed across Brisbane, Australia in November 2012 to assess patterns of green space use. Participants (n = 1479) were asked to provide information on demographics, private yard use, park visitations in the past week, and their orientation toward nature. About 60% of those surveyed had visited a park in the past week, and while this park user population had significantly greater nearby park coverage (within a 250 m radius; p = 0.006), a much stronger determinant of visitation was their higher nature orientation (p<0.00001), suggesting that while both opportunity and orientation are important drivers for park visitation, nature orientation is the primary effect. Park users also spent significantly more time in their yards than non-park users (p<0.00001), suggesting that yard use does not necessarily compensate for lower park use. Park users with stronger nature orientation (i) spent more time in their yard, (ii) traveled further to green spaces, and (iii) made longer visits than park visitors with weaker nature orientation. Overall, our results suggest that measures to increase people''s connection to nature could be more important than measures to increase urban green space availability if we want to encourage park visitation.     

The prizefighter's three bodies

Based on three years of participant observation and apprenticeship in a black boxing gym on Chicago's South Side, this article reconstructs the prizefighter's lived sense and experience of corporeal instrumentality, aesthetics, and ethics ‐ the ‘three bodies’ that together define the distinctive, ‘aisthesis’ of pugilistic practice as corporeal craft and ghetto trade. This serves to argue that professional boxing offers not so much an opportunity for economic betterment as the promise of social difference and even transcendence: the professional ethic of sacrifice enables boxers to tear themselvesfrom the everyday world and to create a moral and sensual universe ‘sui generis’ wherein a transcendent masculine self may be constructed.     

Gender and the dynamics of mobility: reflections on African migrant mothers and ‘transit migration’ in Morocco

By describing the everyday lives of African migrant mothers and their children in Morocco, this paper highlights how migration and ‘immobility’ in so-called ‘transit countries’ are gendering and gendered experiences. Relying on migrants' narratives, the paper demonstrates how migrants' transitions to motherhood create both specific and gendered spaces for agency and particular and gendered constraints upon agency that shape women migrants' mobility dynamics in space and time.     

城市湿地公园使用者评价的影响因素及其行为偏好——以宜昌运河公园为例

城市湿地公园是城市水环境保护和市民活动的共同载体。如何达到保护城市水环境和满足使用者社会需求的平衡是本研究的关键问题。以景观绩效评价为基础,对宜昌运河公园的社会绩效进行了详细量化,并在调查结果上分析研究了影响城市湿地公园使用者评价的原因,以及在城市湿地公园内使用者的行为偏好和季节变化下使用者满意度和行为模式的变化情况,并提出了设计建议。结果表明,城市湿地公园的水环境治理目标与城市居民的公园服务需求是统一的。但是在公园生态和社会效益之间还是存在着冲突关系,如湿地面积和活动空间面积的权衡,消减河流污染物和维持公园水景质量的权衡以及湿地生境冬季景观效果不佳降低使用者满意度的情况。     

Editorial: Taking genetics seriously

Since 2007, consumer genomics companies have marketed personal genome scanning services to assess users' genetic predispositions to a variety of complex diseases and traits. This study investigates early users' reasons for utilizing personal genome services, their evaluation of the technology, how they interpret the results, and how they incorporate the results into health-related decision-making. The analysis contextualizes early users' relationships to the technology, the knowledge generated by it, and how it mediates their relationship to their own health and to biomedicine more broadly. The results reveal that early users approach personal genome scanning with both optimism for genomic research and skepticism about the technology's current capabilities, which runs contrary to concerns that consumers may be ill equipped to interpret and understand genome scan results. These findings provide important qualitative insight into early users' conceptualizations of personal genomic risk assessment and illuminate their involvement in configuring this technology in the making.     

From shared to distinct self–other representations in empathy: evidence from neurotypical function and socio-cognitive disorders

Neuroscientific research has identified two fundamental components of empathy: shared emotional representations between self and other, and self–other distinction. The concept of shared representations suggests that during empathy, we co-represent another person''s affect by engaging brain and bodily functions underpinning the first-hand experience of the emotion we are empathizing with. This possible grounding of empathy in our own emotional experiences explains the necessity for self–other distinction, which is the capacity to correctly distinguish between our own affective representations and those related to the other. In spite of the importance of these two components in empathy, several aspects still remain controversial. This paper addresses some of them and focuses on (i) the distinction between shared activations versus representations, raising the question what shared representations entail in terms of the underlying neural mechanisms, (ii) the possible mechanisms behind self–other distinction in the cognitive and the affective domains, and whether they have distinct neural underpinnings and (iii) the consequences associated with a selective impairment of one of the two components, thereby addressing their importance in mental disorders such as autism spectrum disorders, psychopathy and alexithymia.     

Two Types of Well Followed Users in the Followership Networks of Twitter

In the Twitter blogosphere, the number of followers is probably the most basic and succinct quantity for measuring popularity of users. However, the number of followers can be manipulated in various ways; we can even buy follows. Therefore, alternative popularity measures for Twitter users on the basis of, for example, users'' tweets and retweets, have been developed. In the present work, we take a purely network approach to this fundamental question. First, we find that two relatively distinct types of users possessing a large number of followers exist, in particular for Japanese, Russian, and Korean users among the seven language groups that we examined. A first type of user follows a small number of other users. A second type of user follows approximately the same number of other users as the number of follows that the user receives. Then, we compare local (i.e., egocentric) followership networks around the two types of users with many followers. We show that the second type, which is presumably uninfluential users despite its large number of followers, is characterized by high link reciprocity, a large number of friends (i.e., those whom a user follows) for the followers, followers'' high link reciprocity, large clustering coefficient, large fraction of the second type of users among the followers, and a small PageRank. Our network-based results support that the number of followers used alone is a misleading measure of user''s popularity. We propose that the number of friends, which is simple to measure, also helps us to assess the popularity of Twitter users.     

As Facts and Chats Go Online,What Is Important for Adolescents with Type 1 Diabetes?

Background

Continued refinement of resources for patient information, education and support is needed. Considering the rapid development of new communication practices, the perspectives of young people themselves warrant more attention using a wide research focus. The purpose of this study was to understand information-seeking behaviours, Internet use and social networking online in adolescents with type 1 diabetes (T1DM). This applied to their everyday life, including the context of diabetes and their experiences and need of contact with T1DM peers.

Methodology/Principal Findings

Twenty-four adolescents aged 10–17 years with T1DM were recruited from a county hospital in the south-east of Sweden. Qualitative data were obtained using eight focus groups, wherein each participant engaged in a 60–90 minute video/audio-recorded session. The focus group data were transcribed and analysed using qualitative content analysis. Some demographic and medical information was also collected. The three main categories that were identified; Aspects of Security, Updating, and Plainness and their sub-categories gave significant information about how to enhance information retrieval and peer contacts related to T1DM. Regarding the persons'' information-seeking behaviour, Internet use, and use of social media some differences could be identified depending on gender and age.

Conclusions/Significance

Sensitivity and adaptation to users'' needs and expectations seem crucial in the development of future online resources for adolescents with T1DM. To start with, this could mean applying a wider range of already existing information and communication technologies. Health practitioners need to focus on the areas of security of information and communication, frequency of updating, and simplicity of design-less is more.     

Disability and <Emphasis Type="Italic">Depression</Emphasis>

Here, Ann Cvetkovich, interviewed by Abby Wilkerson, brings Cvetkovich’s influential cultural studies analysis of depression explicitly into conversation with disability studies. Cvetkovich understands “feeling bad” (a term she prefers to “depression”) as a defining affective state under neoliberalism. Drawing on a distinctive historical/cultural archive, she challenges the atomism of the neoliberal medical model that frames depression and affective distress more generally as the result of faulty brain chemistry—individual organisms gone awry. Instead, she traces these common experiences to sociopolitical phenomena ranging from current neoliberal demands for productivity as exemplified in university life, to histories of colonization, slavery, and displacement. The conversation considers the value of disability frameworks for understanding mental health diagnoses and the intersections of social institutions, bodily practices, and everyday affective life.     

Optimizing Online Social Networks for Information Propagation

Online users nowadays are facing serious information overload problem. In recent years, recommender systems have been widely studied to help people find relevant information. Adaptive social recommendation is one of these systems in which the connections in the online social networks are optimized for the information propagation so that users can receive interesting news or stories from their leaders. Validation of such adaptive social recommendation methods in the literature assumes uniform distribution of users'' activity frequency. In this paper, our empirical analysis shows that the distribution of online users'' activity is actually heterogenous. Accordingly, we propose a more realistic multi-agent model in which users'' activity frequency are drawn from a power-law distribution. We find that previous social recommendation methods lead to serious delay of information propagation since many users are connected to inactive leaders. To solve this problem, we design a new similarity measure which takes into account users'' activity frequencies. With this similarity measure, the average delay is significantly shortened and the recommendation accuracy is largely improved.     

On the reciprocal interaction between believing and feeling: an adaptive agent modelling perspective

An agent’s beliefs usually depend on informational or cognitive factors such as observation or received communication or reasoning, but also affective factors may play a role. In this paper, by adopting neurological theories on the role of emotions and feelings, an agent model is introduced incorporating the interaction between cognitive and affective factors in believing. The model describes how the strength of a belief may not only depend on information obtained, but also on the emotional responses on the belief. For feeling emotions a recursive body loop between preparations for emotional responses and feelings is assumed. The model introduces a second feedback loop for the interaction between feeling and belief. The strength of a belief and of the feeling both result from the converging dynamic pattern modelled by the combination of the two loops. For some specific cases it is described, for example, how for certain personal characteristics an optimistic world view is generated in the agent’s beliefs, or, for other characteristics, a pessimistic world view. Moreover, the paper shows how such affective effects on beliefs can emerge and become stronger over time due to experiences obtained. It is shown how based on Hebbian learning a connection from feeling to belief can develop. As these connections affect the strenghts of future beliefs, in this way an effect of judgment ‘by experience built up in the past’ or ‘by gut feeling’ can be obtained. Some example simulation results and a mathematical analysis of the equilibria are presented.     

Reduced Attentional Scope in Cocaine Polydrug Users

Cocaine is Europe''s second preferred recreational drug after cannabis but very little is known about possible cognitive impairments in the upcoming type of recreational cocaine user (monthly consumption). We asked whether recreational use of cocaine impacts early attentional selection processes. Cocaine-free polydrug controls (n = 18) and cocaine polydrug users (n = 18) were matched on sex, age, alcohol consumption, and IQ (using the Raven''s progressive matrices), and were tested by using the Global-Local task to measure the scope of attention. Cocaine polydrug users attended significantly more to local aspects of attended events, which fits with the idea that a reduced scope of attention may be associated with the perpetuation of the use of the drug.     

Designing for emotion (among other things)

Using computational approaches to emotion in design appears problematic for a range of technical, cultural and aesthetic reasons. After introducing some of the reasons as to why I am sceptical of such approaches, I describe a prototype we built that tried to address some of these problems, using sensor-based inferencing to comment upon domestic ‘well-being’ in ways that encouraged users to take authority over the emotional judgements offered by the system. Unfortunately, over two iterations we concluded that the prototype we built was a failure. I discuss the possible reasons for this and conclude that many of the problems we found are relevant more generally for designs based on computational approaches to emotion. As an alternative, I advocate a broader view of interaction design in which open-ended designs serve as resources for individual appropriation, and suggest that emotional experiences become one of several outcomes of engaging with them.     

GeMS: an advanced software package for designing synthetic genes

A user-friendly, advanced software package for gene design is described. The software comprises an integrated suite of programs—also provided as stand-alone tools—that automatically performs the following tasks in gene design: restriction site prediction, codon optimization for any expression host, restriction site inclusion and exclusion, separation of long sequences into synthesizable fragments, T_m and stem–loop determinations, optimal oligonucleotide component design and design verification/error-checking. The output is a complete design report and a list of optimized oligonucleotides to be prepared for subsequent gene synthesis. The user interface accommodates both inexperienced and experienced users. For inexperienced users, explanatory notes are provided such that detailed instructions are not necessary; for experienced users, a streamlined interface is provided without such notes. The software has been extensively tested in the design and successful synthesis of over 400 kb of genes, many of which exceeded 5 kb in length.     

The Work of Indebtedness: The Traumatic Present of Late Capitalist Chile

In political and biomedical discourses, "posttraumatic stress disorder" has become a set of organizing concepts for trauma and traumatic memory. These concepts, however, are predicated on an understanding of traumatic memory as a discrete etiological event that, when reexperienced, is productive of symptoms. In this essay, I explore alternative framings of trauma that arise out of historical changes in political economic language and from experiences of monetary, historical, and affective indebtedness in Santiago, Chile. This ethnographic research is based in an historically leftist población (poor urban sector) and follows the interwoven narratives of a formerly exiled communist militant and her adopted daughter. Throughout this essay, I describe the mother's attempts to inhabit an untimely language of socialist politics and the daughter's rejection of both this language and her mother's pain. I elaborate on how these attempts are products of and productive of monetary and intersubjective indebtedness in a neoliberal present. By describing the differing historical languages inhabited by these subjects, I attempt to evoke an understanding of trauma not as an individual possession or etiological event, but rather as a referential dissonance in the neoliberal context. This referential dissonance emerges from the gap between the historical languages that inform subjectivities. I explore how such a gap can create contexts in which the everyday itself both threatens the disarticulation of the subject and produces injurious affective relationships. In this way, I interrogate relationships between trauma, recovery, and the everyday.     

Embodied economics: how bodily information shapes the social coordination dynamics of decision-making

To date, experiments in economics are restricted to situations in which individuals are not influenced by the physical presence of other people. In such contexts, interactions remain at an abstract level, agents guessing what another person is thinking or is about to decide based on money exchange. Physical presence and bodily signals are therefore left out of the picture. However, in real life, social interactions (involving economic decisions or not) are not solely determined by a person''s inference about someone else''s state-of-mind. In this essay, we argue for embodied economics: an approach to neuroeconomics that takes into account how information provided by the entire body and its coordination dynamics influences the way we make economic decisions. Considering the role of embodiment in economics—movements, posture, sensitivity to mimicry and every kind of information the body conveys—makes sense. This is what we claim in this essay which, to some extent, constitutes a plea to consider bodily interactions between agents in social (neuro)economics.
