The first demonstrations that the levels of inflammatory cytokines are elevated in patients with depression (1) and that exposure to an inflammatory challenge produces a depressive-like episode in experimental animals (2) instigated a comprehensive research endeavor to unravel the mechanisms through which immune system activation can contribute to the development of depression (3). Considering that microglia play a crucial role in the brain’s response to inflammatory stimuli, extensive research has been dedicated to investigating the involvement of these cells in depression (4).

This book introduces a comprehensive and integrative collection of psychological intergroup interventions. These evidence-based interventions are scientifically established and tested in several real-world contexts of intergroup animosities and tensions, from prejudice and inequality reduction to peace promotion. Intergroup hostility, violence, and discrimination have become more and more prevalent in recent decades. To address this challenge, recently, social scientists have shown an increasing shift from a descriptive to a more interventionist science, developing evidence-based interventions to improve intergroup relations. For the first time, this book includes research on intergroup interventions and their applications to the field, from a global collection of leading voices in the discipline. It also includes a conceptualization of intergroup interventions, a typology of different types of interventions, as well as a guideline for effective development of intergroup interventions. Each chapter focuses on one psychological intergroup intervention, further reviewing a sample of relevant platforms such as education, entertainment, and VR, upon which psychological intergroup interventions can be implemented. With each chapter featuring both intervention research and practical advice for practitioners, this is the ideal companion for researchers and professionals in social psychology, sociology, politics, peace studies and conflict resolution. It will also be of interest to practitioners looking for practical advice to create an impact in the real-world.

Abstract. Neural oscillations in the 8–12 Hz alpha band are thought to represent top–down inhibitory control and to influence temporal resolution: Individuals with faster peak frequencies segregate stimuli appearing closer in time. Recently, this theory has been challenged. Here, we investigate a special case in which alpha does not correlate with temporal resolution: when stimuli are presented amidst strong visual drive. Based on findings regarding alpha rhythmogenesis and wave spatial propagation, we suggest that stimulus-induced, bottom–up alpha oscillations play a role in temporal integration. We propose a theoretical model, informed by visual persistence, lateral inhibition, and network refractory periods, and simulate physiologically plausible scenarios of the interaction between bottom–up alpha and the temporal segregation. Our simulations reveal that different features of oscillations, including frequency, phase, and power, can influence temporal perception and provide a theoretically informed starting point for future empirical studies.

In mediated interactions (e.g. video calls), less information is available about the other. To investigate how this affects our empathy for one another, we conducted an electroencephalogram study, in which 30 human participants observed 1 of 5 targets undergoing painful electric stimulation, once in a direct interaction and once in a live, video-mediated interaction. We found that observers were as accurate in judging others’ pain and showed as much affective empathy via video as in a direct encounter. While mu suppression, a common neural marker of empathy, was not sensitive to others’ pain, theta responses to others’ pain as well as skin conductance coupling between participants were reduced in the video-mediated condition. We conclude that physical proximity with its rich social cues is important for nuanced physiological resonance with the other’s experience. More studies are warranted to confirm these results and to understand their behavioral significance for remote social interactions.

Introduction

Endocrine disrupting chemicals (EDCs) such as phthalates, found in our daily environment, are nowadays suggested to be associated with adverse outcomes. Prenatal exposure was found associated with neurodevelopmental complications such as behavioral difficulties in school age children.

Aim

To explore the association between intrauterine exposure to phthalates and emotional/behavioral development of 24 months old toddlers.

Methods

Women were recruited at 11–18 weeks of gestation and provided spot urine samples, analyzed for phthalate metabolites (DEHP, DiNP, MBzBP). Offspring were examined at 24 months of age, using standard maternal report, regarding developmental and behavioral problems (CBCL, ASQ-3, HOME questionnaires) (N = 158). To explore the associations between metabolite levels and developmental outcomes, multivariate GLM analysis (General Linear Model) was used according to tertiles and developmental scores on each developmental outcome.

Results

Associations of Di-(2-ethylhexyl) phthalate (DEHP) maternal exposure with behavioral-developmental outcomes were found only in boys. Compared with boys with lower DEHP maternal exposure, boys with high DEHP maternal exposure had lower developmental score in personal social abilities in the ASQ-3 questionnaire (50.68 + 8.06 and 44.14 + 11.02, high and low DEHP, respectively, p = 0.03), and more internalizing problems (for example, emotionally reactive score in high and low DEHP: 53.77 + 7.41 and 50.50 + 1.19, respectively, p = 0.029; anxious or depressed score: 53.38 + 5.01 and 50.75 + 1.34, respectively, p = 0.009; and somatic complaints scores 64.03 + 10.1 and 55.84 + 7.84, respectively, p = 0.003), and externalizing problems (49.28 + 8.59 and 43.33 + 9.11, respectively, p = 0.039). No differences were found in the development and behavior problems between high and low DEHP maternal exposure level in girls.

Conclusion

Maternal DEHP metabolite concentrations measured in first trimester urine was associated with children’s emotional/behavioral developmental problems in 24-months old boys, supporting accumulating evidence of DEHP as a potentially harming chemical and call for environmental attention.

The present invention is directed to a pharmaceutical composition, including a method of using same, such as for treating or attenuating a mood disorder in a subject having a high inflammatory state. The pharmaceutical composition and the method of the invention, in some embodiments thereof, comprise suppressing or inhibiting microglia for treating a mood disorder.

The many benefits of online research and the recent emergence of open-source eye-tracking libraries have sparked an interest in transferring time-consuming and expensive eye-tracking studies from the lab to the web. In the current study, we validate online webcam-based eye-tracking by conceptually replicating three robust eye-tracking studies (the cascade effect, n = 134, the novelty preference, n = 45, and the visual world paradigm, n = 32) online using the participant’s webcam as eye-tracker with the WebGazer.js library. We successfully replicated all three effects, although the effect sizes of all three studies shrank by 20–27%. The visual world paradigm was conducted both online and in the lab, using the same participants and a standard laboratory eye-tracker. The results showed that replication per se could not fully account for the effect size shrinkage, but that the shrinkage was also due to the use of online webcam-based eye-tracking, which is noisier. In conclusion, we argue that eye-tracking studies with relatively large effects that do not require extremely high precision (e.g., studies with four or fewer large regions of interest) can be done online using the participant’s webcam. We also make recommendations for how the quality of online webcam-based eye-tracking could be improved.

Our brains constantly generate predictions about the environment based on prior knowledge. Many of the events we experience are consistent with these predictions, while others might be inconsistent with prior knowledge and thus violate our predictions. To guide future behavior, the memory system must be able to strengthen, transform, or add to existing knowledge based on the accuracy of our predictions. We synthesize recent evidence suggesting that when an event is consistent with our predictions, it leads to neural integration between related memories, which is associated with enhanced associative memory, as well as memory biases. Prediction errors, in turn, can promote both neural integration and separation, and lead to multiple mnemonic outcomes. We review these findings and how they interact with factors such as memory reactivation, prediction error strength, and task goals, to offer insight into what determines memory for events that violate our predictions. In doing so, this review brings together recent neural and behavioral research to advance our understanding of how predictions shape memory, and why.
