Is Psychopathy a Mental Disorder or an Adaptation? Evidence From a Meta-Analysis of the Association Between Psychopathy and Handedness

Beyond a Game: A Narrative Review of Psychopathic Traits in Sporting Environments

There has been a growing interest around the broader effects of psychopathic traits, particularly in relation to deviant behaviors and the notion of so-called "successful psychopathy". As significant sociocultural touchstones, sporting events are often characterized by competitiveness and a sense of prestige. However, there has been limited attention towards psychopathic traits across recreational, amateur, and elite sports. Accordingly, we conducted a narrative review synthesizing primary observations on this topic, searching keywords in Scopus, APA PsychNet, and PubMed. Twenty-four academic papers were included in our results, which we thematized around demographic groups, namely: athletes and sport-adjacent non-athletes (i.e., coaches and spectators). Based on empirical findings from the reviewed papers, psychopathic traits could have medicolegal and forensic implications in relation to substance use, aggression, and violence. These could intersect with wider issues around doping, cheating, foul play, and have adverse outcomes for fellow participants, team dynamics, and spectators. Interestingly, our review also indicates that psychopathic traits may have correlations with determination and achievement in sport, echoing developing ideas around "successful psychopathy" in other domains. As such, increased awareness from all stakeholders and further multidisciplinary exchanges are vital to better understand the effects of psychopathic traits in sporting frameworks and their wider consequences.

Taking Sides: Asymmetries in the Evolution of Human Brain Development in Better Understanding Autism Spectrum Disorder

Confirmation from structural, functional, and behavioral studies agree and suggest a configuration of atypical lateralization in individuals with autistic spectrum disorders (ASD). It is suggested that patterns of cortical and behavioral atypicality are evident in individuals with ASDs with atypical lateralization being common in individuals with ASDs. The paper endeavors to better understand the relationship between alterations in typical cortical asymmetries and functional lateralization in ASD in evolutionary terms. We have proposed that both early genetic and/or environmental influences can alter the developmental process of cortical lateralization. There invariably is a “chicken or egg” issue that arises whether atypical cortical anatomy associated with abnormal function, or alternatively whether functional atypicality generates abnormal structure.

Beyond the tensions within transfer theories: implications for adaptive expertise in the health professions

Ensuring trainees develop the flexibility with their knowledge to address novel problems, and to efficiently build upon prior knowledge to learn new knowledge is a common goal in health profession education. How trainees come to develop this capacity to transfer and transform knowledge across contexts can be described by adaptive expertise, which focuses on the ability of some experts to innovate upon their existing knowledge to develop novel solutions to novel problems. While adaptive expertise is often presented as an alternative framework to more traditional cognitivist and constructivist expertise models, it is unclear whether the non-routine and routine forms of transfer it describes are distinct from those described by other accounts of transfer. Furthermore, whether what (e.g., knowledge) is transferred and how (e.g., cognitive processes) differs between these views is still debated. In this review, we describe various theories of transfer and present a synthesis clarifying the relationship between transfer and adaptive expertise. Informed by our analysis, we argue that the mechanisms of transfer in adaptive expertise share important commonalities with traditional accounts of transfer, which when understood, can complement efforts by educators and researchers to foster and study adaptive expertise. We present three instructional principles that may better support transfer and adaptive expertise in trainees: i) identifying and incorporating meaningful variability in practice, ii) integrating conceptual knowledge during practice iii) using assessments of trainees' transfer. Taken together, we offer an integrative perspective to how educational systems and experiences can be designed to develop and encourage adaptive expertise and transfer.
