Lonely hearts and angry minds: Online dating rejection increases male (but not female) hostility

The present work explores the hostile tendencies elicited by romantic rejection in the increasingly common context of online dating. To empirically investigate this issue, we created an ad hoc online dating platform in which fictitious online dating partners romantically rejected heterosexual male and female participants. Results revealed that male-but not female-participants who were rejected by desired dating partners displayed increased hostility. This pattern of findings was consistent across different measures, which considered both aggressive tendencies against the rejecting partners and hostile attitudes against the opposite gender. Further, increased feelings of anger explained the relationship between online romantic rejection and increased male hostility. Our work and its findings have both theoretical and methodological implications for the understanding of interpersonal processes in online interactions and the growing body of literature on online dating

Evolutionary psychology: Controversies, questions, prospects, and limitations

Evolutionary psychology has emerged over the past 15 years as a major theoretical perspective, generating an increasing volume of empirical studies and assuming a larger presence within psychological science. At the same time, it has generated critiques and remains controversial among some psychologists. Some of the controversy stems from hypotheses that go against traditional psychological theories; some from empirical findings that may have disturbing implications; some from misunderstandings about the logic of evolutionary psychology; and some from reasonable scientific concerns about its underlying framework. This article identifies some of the most common concerns and attempts to elucidate evolutionary psychology’s stance pertaining to them. These include issues of testability and falsifiability; the domain specificity versus domain generality of psychological mechanisms; the role of novel environments as they interact with evolved psychological circuits; the role of genes in the conceptual structure of evolutionary psychology; the roles of learning, socialization, and culture in evolutionary psychology; and the practical value of applied evolutionary psychology. The article concludes with a discussion of the limitations of current evolutionary psychology

Tumor Necrosis Factor and Interleukin Modulators for Pathologic Pain States: A Narrative Review

Abstract Chronic pain, a complex and debilitating condition, involves intricate interactions between central and peripheral inflammatory processes. Cytokines, specifically tumor necrosis factor (TNF) and interleukins (IL), are key mediators in the initiation and maintenance of chronic pain states. Sensory neurons expressing receptors for cytokines like TNF, IL-1, and IL-6 are implicated in peripheral sensitization, contributing to increased signaling of painful sensations. The potential of targeting TNF and IL for therapeutic intervention in chronic pain states is the focus of this review, with preclinical and clinical evidence supporting the use of TNF and IL modulators for pain management. The physiological and pathological roles of TNF in neuropathic pain is complex. Experimental evidence highlights the effectiveness of TNF modulation in mitigating pain symptoms in animal models and displays promising outcomes of clinical trials with TNF inhibitors, such as infliximab and etanercept. ILs, a diverse group of cytokines, including IL-1, IL-6, and IL-17, are discussed for their contributions to chronic pain through inflammation and peripheral sensitization. Specific IL modulators, such as secukinumab and tocilizumab, have shown potential in managing chronic neuropathic pain, as demonstrated in various studies and clinical trials. The pharmacokinetics, safety profiles, and challenges associated with TNF and IL modulators highlight the need for cautious medication monitoring in clinical practice. Comparative evaluations have revealed distinct efficacy and safety profiles among different cytokine modulators, emphasizing the need for personalized approaches based on the specific underlying causes of pain. Further research is necessary to elucidate the intricate mechanisms by which cytokines contribute to chronic pain, as well as to understand why they may affect pain differently in various contexts. Additionally, long-term safety profiles of cytokine modulators require more thorough investigation. This continued exploration holds the promise of enhancing our comprehension of cytokine modulation in chronic pain and shaping more potent therapeutic strategies for the future
