The intercorporeality of closing a curtain

Multiple Timescales of Memory in Lateral Habenula and Dopamine Neurons

Everyday joint remembering, from family remembering around the dinner table to team remembering in the operating theatre, relies on the successful interweaving of multiple cognitive, bodily, social and material resources, anchored in specific cultural ecosystems. Such systems for joint remembering in social interactions are composed of processes unfolding over multiple but complementary timescales, which we distinguish for analytic purposes so as better to study their interanimation in practice: (i) faster, lower-levelcoordination processesof behavioral matching and interactional synchrony occurring at timescale t1; (ii) mid-rangecollaborative processeswhich re-evoke past experiences in groups, unfolding at timescale t2; (iii)cooperative processesinvolved in the transmission of memories over longer periods occurring at timescale t3; and (iv)cultural processesand practices operating within distributed socio-cognitive networks over evolutionary and historical timeframes, unfolding at timescale t4. In this paper we survey studies of how the processes operating across these overlapping and complementary timescales constitute joint remembering in social interactions. We describe coordination, collaboration, cooperation, and culture as complementary aspects of interacting to remember, which we consider as a complex phenomenon unfolding over multiple timescales (t1, t2, t3, t4).

It is widely acknowledged that social relationships unfold across multiple time-scales. For example, social interactions that take place over moments, hours, or days also shape relationship change and outcomes over months, years, and even decades. These processes likely unfold in the reverse direction as well: experiences over longer-term timeframes may shape how people interact on a moment-to-moment basis. The increasing availability of intensive longitudinal data and measurement burst designs, as well as creativity in the contexts and modes of data collection--including social media, text messages, and event-contingent sampling--have exploded the possibilities for advancing knowledge on social relationships across multiple time-scales. The aim of this issue is to forward methodological innovations, empirical findings, and future directions in relationship science through the study of social and personal relationships across multiple time-scales.

In everyday life, the stream of affect results from the interaction between past experiences, expectations and the unfolding of events. How the brain represents the relationship between time and affect has been hardly explored, as it requires modeling the complexity of everyday life in the laboratory setting. Movies condense into hours a multitude of emotional responses, synchronized across subjects and characterized by temporal dynamics alike real-world experiences. Here, we use time-varying intersubject brain synchronization and real-time behavioral reports to test whether connectivity dynamics track changes in affect during movie watching. The results show that polarity and intensity of experiences relate to the connectivity of the default mode and control networks and converge in the right temporoparietal cortex. We validate these results in two experiments including four independent samples, two movies and alternative analysis workflows. Finally, we reveal chronotopic connectivity maps within the temporoparietal and prefrontal cortex, where adjacent areas preferentially encode affect at specific timescales.

Animals use past experience to guide future choices. The integration of experiences typically follows a hyperbolic, rather than exponential, decay pattern with a heavy tail for distant history. Hyperbolic integration affords sensitivity to both recent environmental dynamics and long-term trends. However, it is unknown how the brain implements hyperbolic integration. We found that mouse behavior in a foraging task showed hyperbolic decay of past experience, but the activity of cortical neurons showed exponential decay. We resolved this apparent mismatch by observing that cortical neurons encode history information with heterogeneous exponential time constants that vary across neurons. A model combining these diverse timescales recreated the heavy-tailed, hyperbolic history integration observed in behavior. In particular, the time constants of retrosplenial cortex (RSC) neurons best matched the behavior, and optogenetic inactivation of RSC uniquely reduced behavioral history dependence. These results indicate that behavior-relevant history information is maintained across multiple timescales in parallel and that RSC is a critical reservoir of information guiding decision-making.

This study tested the hypothesis that it is easier to take the perspective of another person when one has similar past experience. Volunteer participants (N= 154) were asked to take the perspective of a protagonist in one of four problematic interpersonal situations and then to rate the ease with which they felt able to perspective take and the extent of their personal past experience of similar situations. Similar past experience predicted ease of perspective taking, with the relationship influenced by reflection on past experience. Ease of perspective taking mediated the relationship between similar past experience and participant perceptions of their accuracy in understanding the other person, but ease was not associated with emotional arousal. The findings have potential therapeutic applications for attempts to increase empathy and understanding in people for whom perspective taking may be difficult.

Background: Young adults’ connectedness with and independence from parents have important implications for both their development and family relationships. Although technology plays an increasingly important role in these dynamics, there are few direct observations of how connectedness and independence unfold in the digital world. Little is known of between- and within-person differences in these dynamics. Purpose: This study uses Screenomics to directly observe smartphone interactions between young adults and their parents, and discover whether and how dimensions of connectedness and independence manifest in these interactions at multiple timescales. Research Design, Study Sample, and Data Collection: Screenshot sequences were collected from 10 ethnically diverse young adult (50% female) participants’ smartphones every 5 seconds for up to 1 month (total of 457,905 screenshots). We identified 1413 interaction instances between young adults and their parents (including 359 calls, 1032 messages, and 10 other communication instances). Analysis and Results Digital ethnographic analysis of screenshots revealed multiple themes related to connectedness (emotional support, logistical and financial support, consistent communication) and independence (parent fostering independence, parent intrusiveness/overinvolvement, and young adults’ psychological separation). Quantitative descriptions at different timescales (week, day, hour, moment) revealed within-person and between-person differences in active engagement, reciprocal communication, consistent communication, parent intrusiveness, young adults’ reliance on parents’ support, and young adults’ psychological separation. Conclusion: Findings highlight the need to examine family digital interactions at multiple timescales and the utility of temporally dense and comprehensive Screenomics data in studying social relations.

In view of its increasing importance, and the dearth of information on return migration and its impacts on source households, this study uses data from the 2005 Albania Living Standards Measurement Study survey and assesses the impact of past migration experience of Albanian households on non-farm business ownership through instrumental variables regression techniques. Moreover, considering the differences in earning potentials and opportunities for skill acquisition in different destination countries, the impact of household past migration experience is differentiated by main migrant destinations, namely Greece, and Italy. The study also tests for the hypothesis of the existence of migration cycles, by differentiating the time spent abroad based on the year of return. The empirical results indicate that household past migration experience exerts a positive impact on the probability of owning a non-farm business. While one additional year in Greece increases the probability of household business ownership by roughly 7 percent, a similar experience in Italy or further destinations raises the probability by over 30 percent. Although past migration experience for the period of 1990-2000 is positively associated with the likelihood of owning a household enterprise, a similar impact does not materialize for the period of 2001-2004. The latter finding seems suggestive of the fact that more recent migrants are yet to attain a target level of required savings and skills in order to successfully establish a new business upon return.

This study uses data from the 2005 Albania Living Standards Measurement Study survey to assess the impact of past migration experience of Albanian households on non‐farm business ownership through instrumental variables regression techniques. Considering the differences in earning potentials and opportunities for skill acquisition in different destination countries, we differentiate the impact of past household migration experience by main migrant destinations. The study also explores the heterogeneity of impact based on the timing of migration. The empirical results indicate that past household migration experience exerts a positive impact on the probability of owning a non‐farm business. While one additional year in Greece increases the probability of household business ownership by roughly 6 percent, a similar experience in Italy or farther destinations raises the probability by over 25 percent. Although past household migration experience for the period of 1990–2000 is positively associated with the likelihood of owning a household enterprise, a similar association does not exist for the period of 2001–2004.

135 male college students solved Maier's Hatrack Problem (Maier, 1945) in an experiment designed to evaluate Saugstad's “availability of functions” concept. Saugstad has stated that Ss will solve any problem if they have the necessary functions available. The data indicated that: (1) Ss failing to solve the problem had the necessary or relevant experiences, (2) Ss who solved and those who did not solve the problem had very similar experiences, and (3) selecting the relevant experience resulted in the immediate solution of the problem by a majority of Ss. Contrary to Saugstad's contention, Ss will not necessarily solve a problem if they have the essential functions or past experiences. Recognizing experiences as relevant to a problem's requirements, selecting experiences from a given repertoire, fragmenting experiences into parts, and recombining parts of experiences into solutions are functions that seem essential, yet are excluded when problem solving is regarded as a form of generalized learning. Three groups of problem solvers, differing in their degrees of success with the Hatrack Problem, had strikingly similar available functions, but differed in the way they selected from their past experiences when confronted with the problem of finding uses for the pole structure.

This chapter reviews research on the association between alcohol involvement and marital dissolution. It describes an emerging theoretical framework for research on substance use and marriage based on social psychology, relationship science, and developmental science that (1) includes both spouses and focuses on the dyad as the unit of analysis to explicitly test for husband and wife differences and dyadic patterns of alcohol involvement and (2) assesses core constructs across multiple timescales, with a focus on daily processes as potential linkages between real-time marital interactions and outcomes that unfold over longer timescales. This framework can strengthen connections between social psychological and developmental theory, inform basic research on alcohol and social interaction processes, and potentially enhance prevention and treatment efforts by identifying the mechanisms underlying the associations between alcohol involvement and negative marital outcomes.

Language is one of the most crucial factors which influence social experiences and relations of transnational migrants. Moreover, crossing borders becomes an important strategy for acquiring valuable linguistic resources in the globalized neoliberal economy. For instance, throughjogi yuhak(Early Study Abroad), the transnational educational migration of Korean middle class families, parents aim to provide their children with the opportunities to acquire multilingual competence as important skills for them to become competitive neoliberal workers in the global economy. However, anxiety and insecurity are inherent in transnational movement in the sense that relocation necessarily implies adjustment to new conditions of life. This paper investigates the anxieties and insecurities which Koreanjogi yuhakfamilies experience during their transnational educational migration. Based on an ethnographic study on Korean educational migrant families in Singapore, it explores how uncertainty and tension serve as an unavoidable aspect of strategic migratory choices and how the fierce pursuit of neoliberal subjectivity through global mobility works to increase the anxieties of the families. Koreanjogi yuhakfamilies’ constant negotiation between conflicting expectations and options across multiple scales of Time and Space in their migratory trajectories leads to awareness of the complex relationship between language and space, resulting in increasing anxiety and insecurity.

The similar past pain experience evokes both observational contagious pain and consolation in stranger rat observers

The ability to recognize the behavior of individuals is of great interest in the general field of safety (e.g. building security, crowd control, transport analysis, independent living for the elderly). Here we report a new real-time acoustic system for human action and behavior recognition that integrates passive audio and active micro-Doppler sonar signatures over multiple time scales. The system architecture is based on a six-layer convolutional neural network, trained and evaluated using a dataset of 10 subjects performing seven different behaviors. Probabilistic combination of system output through time for each modality separately yields 94% (passive audio) and 91% (micro-Doppler sonar) correct behavior classification; probabilistic multimodal integration increases classification performance to 98%. This study supports the efficacy of micro-Doppler sonar systems in characterizing human actions, which can then be efficiently classified using ConvNets. It also demonstrates that the integration of multiple sources of acoustic information can significantly improve the system's performance.
