We will hunt them down: How social dominance orientation and right-wing authoritarianism fuel ethnic persecution of immigrants in fundamentally different ways

Despite the fact that SDO and RWA are correlated with one another and both predict support for ethnic persecution of immigrants, it is argued that this aggression is provoked for very different reasons. For authoritarians, outgroup aggression against immigrants should primarily be provoked by immigrant refusal to assimilate into the dominant culture because this violates ingroup conformity. In contrast, SDO should be associated with aggression against immigrants who do assimilate into the dominant culture because this blurs existing status boundaries between groups. Using samples of American and Swiss college students, the data were consistent with this status boundary enforcement hypothesis regarding social dominators and largely consistent with the ingroup conformity hypothesis regarding authoritarians. National and ethnic identification did not account for these results. The results further support the argument that outgroup prejudice and discrimination is most fruitfully seen as an interactive function of individual differences and situational constraints.     

The Individualised Patient‐Progress System: A decade of international collaborative networking

Background: The backstage of research projects is seldom presented to the general audience, in particular, how the research questions emerged, how the team interacted and how the methods and design were decided upon. Aim: In this paper we will recount the story behind an international practice‐based research network for personalising health assessment, the joint journey of researchers and therapists from three different countries in creating the Individualised Patient‐Progress System (IPPS). Results: We first describe how the idea of the IPPS emerged; then we show how IPPS is being piloted and integrated into clinical practice. Next, we present the views of therapists and researchers who have been part of this project. Conclusions: We discuss some lessons learned from this 14‐year collaborative research programme.     

Timing in cognition and EEG brain dynamics: discreteness versus continuity

This article provides an overview of recent developments in solving the timing problem (discreteness vs. continuity) in cognitive neuroscience. Both theoretical and empirical studies have been considered, with an emphasis on the framework of operational architectonics (OA) of brain functioning (Fingelkurts and Fingelkurts in Brain Mind 2:291-29, 2001; Neurosci Biobehav Rev 28:827-836, 2005). This framework explores the temporal structure of information flow and interarea interactions within the network of functional neuronal populations by examining topographic sharp transition processes in the scalp EEG, on the millisecond scale. We conclude, based on the OA framework, that brain functioning is best conceptualized in terms of continuity-discreteness unity which is also the characteristic property of cognition. At the end we emphasize where one might productively proceed for the future research.     

Functional Status, Receipt of Help, and Perceived Health

We model the effects of disability, functional limitation, and receipt of help on perceived health. This analysis specifies a model with two dimensions of disability and three dimensions of functional limitation, including upper body disability, lower body disability, basic activities of daily living (ADLs), household ADLs, and advanced ADLs. The latent variables of receiving help are modeled for each of the ADLs as intervening between limitations and perceived health. The results show that instrumental social support in the form of receiving help for ADLs has no substantive independent effect on perceived health. In addition, receiving instrumental social support shows a pattern of task-specific responses to individual measures of need. Implications for both caregiver and care recipient are discussed.     

The parental support networks of mothers and fathers: A multidimensional approach

This paper argues for a multidimensional approach to the study of the social support networks of mothers and fathers of young children. Network structure (e. g. size, density, member characteristics), support content (e. g. emotional, informational, economic and child care) and support quality (e. g. helpfulness, satisfaction with support, conflict associated with support and willingness to access support in future need) are distinguished. The goals of the study were: (1) to empirically test the multidimensionality of parental support networks; (2) to assess the relations among these three dimensions for mothers and for fathers; and (3) to examine how couples' support networks are interrelated. Individual at-home interviews were conducted with 100 parents to derive measures of parental support structure, content and quality. Fathers (N = 31) were compared to their spouses (N = 31) and to a comparison group of demographically similar married mothers (N = 38). For all three groups, the same three predicted dimensions emerged in the factor structure of their networks; in general, few gender differences were found. However, relations among structure, content and quality differed by gender, with network structure predicting support content and quality only for mothers. The network structure of couples was positively correlated, and overlap in network members was related to own and spouse's network helpfulness, satisfaction and child care support.     

Coding infant engagement in the Face-to-Face Still-Face paradigm using deep neural networks

BackgroundThe Face-to-Face Still-Face (FFSF) task is a validated and commonly used observational measure of mother-infant socio-emotional interactions. With the ascendence of deep learning-based facial emotion recognition, it is possible that common complex tasks, such as the coding of FFSF videos, could be coded with a high degree of accuracy by deep neural networks (DNNs). The primary objective of this study was to test the accuracy of four DNN image classification models against the coding of infant engagement conducted by two trained independent manual raters.Methods68 mother-infant dyads completed the FFSF task at three timepoints. Two trained independent raters undertook second-by-second manual coding of infant engagement into one of four classes: 1) positive affect, 2) neutral affect, 3) object/environment engagement, and 4) negative affect.ResultsTraining four different DNN models on 40,000 images, we achieved a maximum accuracy of 99.5% on image classification of infant frames taken from recordings of the FFSF task with a maximum inter-rater reliability (Cohen's κ-value) of 0.993.LimitationsThis study inherits all sampling and experimental limitations of the original study from which the data was taken, namely a relatively small and primarily White sample.ConclusionsBased on the extremely high classification accuracy, these findings suggest that DNNs could be used to code infant engagement in FFSF recordings. DNN image classification models may also have the potential to improve the efficiency of coding all observational tasks with applications across multiple fields of human behavior research.     

Individual differences in harm-related moral values are associated with functional integration of large-scale brain networks of emotional regulation

Emotions affects moral judgements, and controlled cognitive processes regulate those emotional responses during moral decision making. However, the neurobiological basis of this interaction is unclear. We used a graph theory measurement called participation coefficient (‘PC’) to quantify the resting-state functional connectivity within and between four meta-analytic groupings (MAGs) associated with emotion generation and regulation, to test whether that measurement predicts individual differences in moral foundations-based values. We found that the PC of one of the MAGs (MAG2) was positively correlated with one of the five recognized moral foundations–the one based on harm avoidance. We also found that increased inter-module connectivity between the ventromedial prefrontal cortex, dorsolateral prefrontal cortex and middle temporal gyrus with other nodes in the four MAGs was likewise associated with higher endorsement of the Harm foundation. These results suggest that individuals' sensitivity to harm is associated with functional integration of large-scale brain networks of emotional regulation. These findings add to our knowledge of how individual variations in our moral values could be reflected by intrinsic brain network organization and deepen our understanding of the relationship between emotion and cognition during evaluations of moral values.     

The protective role of social network factors during the COVID-19 pandemic in the United States

The present study examined the relationship between COVID-19 threat perception, isolating health precautions, and loneliness. As a test of the stress-buffering hypothesis (Cohen & Wills, 1985), this study also examined if social network factors representing various aspects of social support moderated, or weakened, the relationship between threat perception, isolating health precautions, and loneliness. Participants (N = 1149) provided information about themselves, as well as 15 other people they know via an online survey. We found that structural and compositional social network factors, density, number of close alters, network threat perception, network covid cautiousness and number of vaccinated alters all negatively related to loneliness. Further, using moderated mediation analyses, we found that network threat perception and network covid cautiousness moderated the indirect relationship between threat perception and loneliness through precautions. At high levels of these factors, the mediation was less likely to be significant suggesting that the social network factors may buffer people from the loneliness that sometimes comes with engaging in isolating health precautions in response to the perceived threat of COVID-19.

The social network of solidarity with migrants: The role of perceived injunctive norms on intergroup helping behaviors

Using an ego-centered network approach, we examine across two studies whether and how injunctive network norms—behaviors that are approved by alters—are related to majority members’ decisions to participate in helping actions supporting migrants. We hypothesize that the more people perceive their personal social networks as positive toward humanitarian actions for migrants, the more they consider their opinions on migration issues as self-defining, and the more they are willing to mobilize in helping behaviors. With a name generator approach, we collected personal social network data among majority members of Belgian, mobilized volunteers (Study 1, N = 204) and Swiss, non-mobilized participants (Study 2, N = 247). Results demonstrate the impact of injunctive network norms in promoting and maintaining helping actions for migrants, and the role of self-defining attitudes. Overall, the results highlight the importance of injunctive norms within personal social networks for participation in intergroup helping behaviors.
