Evolutionary perspectives on substance and behavioural addictions: Distinct and shared pathways to understanding, prediction and prevention

Addiction poses significant social, health, and criminal issues. Its moderate heritability and early-life impact, affecting reproductive success, poses an evolutionary paradox: why are humans predisposed to addictive behaviours? This paper reviews biological and psychological mechanisms of substance and behavioural addictions, exploring evolutionary explanations for the origin and function of relevant systems. Ancestrally, addiction-related systems promoted fitness through reward-seeking, and possibly self-medication. Today, psychoactive substances disrupt these systems, leading individuals to neglect essential life goals for immediate satisfaction. Behavioural addictions (e.g. video games, social media) often emulate ancestrally beneficial behaviours, making them appealing yet often irrelevant to contemporary success. Evolutionary insights have implications for how addiction is criminalised and stigmatised, propose novel avenues for interventions, anticipate new sources of addiction from emerging technologies such as AI. The emerging potential of glucagon-like peptide 1 (GLP-1) agonists targeting obesity suggest the satiation system may be a natural counter to overactivation of the reward system.

The Role of Cognitive Emotion Regulation for Making and Keeping Friend and Conflict Networks

We used social network analysis (SNA) to examine how adaptive ER strategies (acceptance, positive reappraisal, refocusing, and putting in perspective) and maladaptive ER strategies (rumination, catastrophizing, self- and other-blame) predict the creation and maintenance of friendship and conflict relationships within a mixed-gender social group. Participants (n = 193, 53% female, M age = 19.4 years, 62.1% White) reported on emotion regulation, friendship, and conflict nominations at two time points. Stochastic actor-oriented models revealed that similarity in endorsement of adaptive ER strategies predicted maintenance of friendship and conflict relationships over time. However, new conflict relationships were more likely to form between those who differed in use of adaptive ER. Finally, more frequent use of maladaptive ER strategies was related to termination of existing conflict ties and the creation of new ones. Deploying social network analysis as a methodology for examining social relationships enables the unpacking the dynamics of multiple social relationships (friend and conflict), identifying the role of ER for structuring of social relationships among group members. Although cognitive ER is an intra-individual process, it fundamentally occurs within a social environment and our results advance the knowledge of how ER contributes to how this social environment is created in a first place.

A Paradigm Shift for a Transition to Sustainable Urban Transport

The traffic-engineering methods of planning based on the predict-and-provide principle have self-enforcing effects of induced traffic and an unhealthy environment for humans as well as for the planet. The paper aims to demonstrate that such methods keep cities stuck in a sort of path dependency with transport technologies and urban environment and to find evidence that something is changing in theory, trends, and practice. A systematic and extensive literature review has been used to identify and understand the problems, to recognise the changes taking place, and to examine the solutions. The main findings are the causes of how these problems could have happened and continue to do so regardless of the huge negative effects and the recognition that a paradigm shift is emerging as the sum of methods and achievements developed by the community of academics, experts, practitioners, policymakers, and urban communities. The findings can have practical, effective implications as the determinants of a new transport policy paradigm that shows the way out of the trap of path dependency. The originality of the approach lies in having expanded and applied the concept of anomalies of the theory to the adverse effects of technologies and the mismatch between people and the modern urban environment. The new paradigm is already showing its practical effectiveness in solving real problems by adapting cities and technologies to human nature and developing a more holistic human-centric planning method.

Loneliness Modulates Automatic Attention to Warm and Competent Faces: Preliminary Evidence From an Eye-Tracking Study

Social connections are essential for human survival. Loneliness is a motivational factor for building and maintaining social connections. Automatic attention occurs with little cognitive effort and plays a key role in detecting biologically salient events, such as human faces. Although previous studies have investigated the effect of loneliness on social behavior, the effect of loneliness on automatic attention to human faces remains largely unknown. The present study investigated the effects of loneliness on automatic visual attention to warmth and competence facial information, which determines facial attraction. This study included 43 participants who rated warmth and competence facial information. Then, they engaged with the target-distractor paradigm in which they saw two house images at the top and bottom and indicated whether the images were identical. During the task, we presented two faces as distractors and measured visual attention toward the faces as automatic attention because participants did not have to attend to the faces. The results showed an interactive effect between subjective loneliness and facial information on automatic attention. Warm targets automatically captured the attention of people feeling relatively lonely, whereas competent targets automatically captured the attention of those who felt less lonely. These results suggest that loneliness adaptively influences automatic processing of social information.

An Exploration of Psychosocial Pathways of Parks' Effects on Health: A Qualitative Study

Urban green space has been positively associated with psychological and physical health. However, the linkage between exposure to parks and health outcomes remains unclear. The current study examined the meanings that people assign to city parks, as a way to understand the pathways by which parks exert their effects on health. We conducted qualitative interviews with twenty culturally diverse residents in New York City. Thematic analysis was performed on the qualitative data. Results showed that all themes identified were related to parks fulfilling a basic human need for connection to (1) family, loved ones, and friends; (2) community and neighborhood; (3) self; and (4) nature. Based on these data, we proposed a human-centered framework for future research and interventions aimed at catalyzing parks as a vehicle to improve health and wellbeing. A human-centered approach emphasizes targeting the deep-seated needs and values of those we seek to engage and for whom health promotion and disease prevention efforts are designed. Our study shows that park transformations need to incorporate careful considerations of the human need for connection on multiple levels, so that park usage and its consequent health benefits may be optimized.

The (Diverse) Company You Keep: Content and Structure of Immigrants’ Social Networks as a Window Into Intercultural Relations in Catalonia

This research examines how the social networks of immigrants residing in a European bicultural and bilingual context (Catalonia) relate to levels of adjustment (both psychological and sociocultural) and to bicultural identity integration (BII). Moroccan, Pakistani, Ecuadorian, and Romanian immigrants residing in Barcelona nominated 25 individuals (i.e., alters) from their habitual social networks and provided demographic (e.g., ethnicity), relationship type (e.g., family, friend, neighbor), and structural (who knew whom) information for each of these alters. Even after controlling for individual-level demographic and acculturation variables, the content and structure of immigrants’ personal social networks had unique associations with both types of adjustment and with BII. Specifically, the overall degree of cultural diversity in the network and the amount of Catalan (but not Spanish) “weak” ties (i.e., acquaintances, colleagues, neighbors) positively predicted these outcomes. Amount of interconnectedness between local coethnic and Catalan/Spanish alters also predicted sociocultural adjustment and BII positively. Finally, against a “culture and language similarity” hypothesis, Moroccan and Pakistani participants had social networks that were more culturally integrated, relative to Ecuadorians and Romanians. Results from this study attest to the importance of examining actual intercultural relations and going beyond individuals’ reported acculturation preferences to understand immigrants’ overall adaptation and cultural identity dynamics. Furthermore, results highlight the interplay between interculturalism experienced at the intrapersonal, subjective level (i.e., BII), and at the meso-level (i.e., having culturally diverse networks that also include interethnic ties among alters).

An Introduction to Social Network Analysis for Personality and Social Psychologists

Social network analysis (SNA) is a methodology for studying the connections and behavior of individuals within social groups. Despite its relevance to social and personality psychology, SNA has been underutilized in these fields. We first examine the paucity of SNA research in social and personality journals. Next we describe methodological decisions that must be made before collecting social network data, with benefits and drawbacks for each. We discuss common SNAs and give an overview of software available for SNA. We provide examples from the literature of SNA for both one-mode and two-mode network data. Finally, we make recommendations to researchers considering incorporating SNA into their research.

More than Social–Cultural Influences: A Research Agenda for Evolutionary Perspectives on Prosocial Media Effects

Prosocial media effects, short- and long-term intrapersonal changes in prosocial personality traits, values, emotions, and behavior caused by media use, have attracted much less attention than media violence research. Empirical examinations of current theories of prosocial media effects have focused on the indirect effects of prosocial media that explain why exposure to it results in prosocial behavior. However, they have neglected other types of media effects. Further, because of philosophical biases in the field of communication, only the social-cultural perspective has been used to explain the psychological antecedents and consequences of prosocial media effects. The origins and ultimate functions of prosociality in the processes of media effects are unknown. The intersection of evolutionary theories and media effects theories provides a more comprehensive explanation of prosocial media effects. Using various evolutionary perspectives on altruism, reciprocity, and cooperation, this article synthesizes 4 types of prosocial media effects: selective, indirect, conditional, and transactional, suggesting that the dramatic prosocial media learning process should be considered from a comprehensive nature-nurture interactive view. The research agenda, implications, and recent methodological advances are highlighted.

The origins and nature of compassion focused therapy

Compassion focused therapy (CFT) is rooted in an evolutionary, functional analysis of basic social motivational systems (e.g., to live in groups, form hierarchies and ranks, seek out sexual, partners help and share with alliances, and care for kin) and different functional emotional systems (e.g., to respond to threats, seek out resources, and for states of contentment/safeness). In addition, about 2 million years ago, (pre-)humans began to evolve a range of cognitive competencies for reasoning, reflection, anticipating, imagining, mentalizing, and creating a socially contextualized sense of self. These new competencies can cause major difficulties in the organization of (older) motivation and emotional systems. CFT suggests that our evolved brain is therefore potentially problematic because of its basic 'design,' being easily triggered into destructive behaviours and mental health problems (called 'tricky brain'). However, mammals and especially humans have also evolved motives and emotions for affiliative, caring and altruistic behaviour that can organize our brain in such a way as to significantly offset our destructive potentials. CFT therefore highlights the importance of developing people's capacity to (mindfully) access, tolerate, and direct affiliative motives and emotions, for themselves and others, and cultivate inner compassion as a way for organizing our human 'tricky brain' in prosocial and mentally healthy ways.

PSI: A Computational Architecture of Cognition, Motivation, and Emotion

This article describes PSI theory, which is a formalized computational architecture of human psychological processes. In contrast to other existing theories, PSI theory not only models cognitive, but also motivational and emotional processes and their interactions. The article starts with a brief overview of the theory showing the connections between its different parts. We then discuss the theory's components in greater detail. Key constructs and processes are the five basic human needs, the satisfaction of needs using the cognitive system, including perception, schemas in memory, planning, and action. Furthermore, emotions are defined and the role of emotions in cognitive and motivational processes is elaborated, referring to a specific example. The neural basis of the PSI theory is also highlighted referring to the “quad structure,” to specific brain areas, and to thinking as scanning in a neural network. Finally, some evidence for the validity of the theory is provided.

The effects of friendship network popularity on depressive symptoms during early adolescence: moderation by fear of negative evaluation and gender

We integrated a social network analysis and developmental perspectives to examine the effects of friendship network popularity on depressive symptoms during early adolescence. We explored whether the association between social status processes (i.e., friendship network popularity) and depressive symptoms was moderated by socio-cognitive aspects of peer relations (i.e., a fear of negative evaluation by peers) and gender. This longitudinal study was conducted with a sample of 367 adolescents (48.5 % female; M age = 11.9 years; 9 % European American, 19 % African American, 7 % Native American, 60 % Latino(a), 5 % other) attending sixth and seventh grades at Time 1. Results indicated that, for males with high levels of fear of negative evaluation, friendship network popularity was associated negatively with increases in depressive symptoms. Conversely, for females with high levels of fear of negative evaluation, friendship network popularity was associated positively with increases in depressive symptoms. Theoretical and clinical implications are discussed.
