The nature (and nurture) of personality disorders

Personality disorders have a long history in the literature but a short scientific history. The point prevalence of personality disorders is 10%, but the lifetime prevalence is probably 30–40%. Genetic factors contribute to around 40–50% of the variation in the development of personality disorders. The effect of shared environment is very small or non‐existent. Some researchers have tried to promote gene‐environment interaction. However, in reality, the studies investigated gene‐situation interaction, as the “environment” may in reality be partly of a genetic nature. Thus, we are dealing with an unknown part of gene‐gene interaction. Gene‐experience (not gene‐environment) correlations are the rule in human life. Personality disorders co‐occur (are comorbid) with symptom disorders (Axis I) and correlate with common personality dimensions. Possibly, the concept of personality disorder could merge with dysfunctional personality types. But it is likely that the concept will survive on its own.     

The nature and nurture of expertise: a fourth dimension

One formative idea behind the workshop on expertise in Berkeley in August of 2010 was to develop a viable “trading zone” of ideas, which is defined as a location “in which communities with a deep problem of communication manage to communicate” (Collins et al. 2010, p. 8). In the current case, the goal is to have a trading zone between philosophers, sociologists, and psychologists who communicate their ideas on expertise such that productive interdisciplinary collaboration results. In this paper, I review Harry Collins' three-dimensional model of expertise and provide a very brief and non-inclusive overview of a psychological response. In addition, I propose an addendum to the model by adding a fourth—natural talent—dimension.     

The continuing legacy of nature versus nurture in biolinguistics

Theories of language evolution that separate biological and cultural contributions perpetuate a false dichotomy between nature and nurture. The explanatory power of future theories will depend on acknowledging the reality of gene–culture interaction and how it makes language possible.     

Beyond nature/nurture: Buddhism and biology on interdependence

Buddhist temples are emblematic of many Asian countries in their tourism promotions, but little is known about how monks, laypeople, guides, and local or foreign tourists experience these religious heritage sites. In late developed and developing Asian countries these Buddhist sites fulfil complex social and symbolic roles involving differing functions and expectations. But how these temples can fulfil these complex demands and avoid becoming similar to a museum or a theme park is unclear. Using qualitative analysis this research examined temple users experiences of the architecture, artefacts, gardens, rituals, and users at the Bulguk Temple precinct in Korea and identified several dimensions of the sense of place that temple users experience. A resulting sense of place matrix includes believer, novice, leisure, and heritage experiences that users access depending on their grasp of the core knowledge and the symbolic materialities in the temple precinct. This provides a starting point for the skilful management of Buddhist sites facing mounting pressures from increasing visitor numbers particularly from heritage and leisure tourists. An indigenous approach to the diversity of Buddhist veneration settings and their users is recommended. Practical implications and further research are suggested.

Differential perceptions of and feelings about sibling children: implications for research on parenting stress

Parenting stress is influenced by parents' perceptions of their relationships with their children, which can vary widely for each parent depending on which child in the family is being considered. Because this within‐parent variation is rarely studied, we investigated some of the differential perceptions that arise with respect to children's behaviour problems and parent–child negativity/positivity. Participants included a national sample of adoptive parents of 486 pairs of genetically unrelated siblings. Mothers reported different perceptions of their sibling children, and within the family, the child who was rated higher in behaviour problems also was regarded with more negativity and less positivity. Furthermore, the magnitude of the difference was uncorrelated with various indicators of the family and home environment, including parental education and occupational prestige, type of housing and crowding in the home, and progressive versus traditional childrearing attitudes. This pattern of results was consistent with three previously published sibling studies utilizing similar methods. The results point to the importance of examining child effects and within‐parent differences in subjective aspects of the parenting experience. Copyright © 2005 John Wiley & Sons, Ltd.     

Theoretical and methodological considerations in cross-generational research on parenting and child aggressive behavior

The four studies in this special issue represent important advances in research on the intergenerational transmission of aggressive behavior. In this commentary, we review the key features and findings of these studies, as well as our own cross-generational study of aggression, the Columbia County Longitudinal Study. Next, we consider important theoretical issues (e.g., defining and operationalizing raggression and parenting assessing reciprocal effects of parenting and child aggression; identifying the ages at which aggression should be assessed across generations; broadening the investigation of contextual and individual factors). We then discuss several methodological issues (e.g., determining the most informative measurement intervals for assessing prospective effects; sampling considerations; measuring potential moderating and mediating variables that might explain cross-generational continuities and discontinuities in parenting and aggression). Finally, we raise implications of cross-generational research for designing interventions targeting the reduction and prevention of child aggression.     

The impact of parenting on conduct disorder in Jamaican male adolescents.

The present study examined the feasibility of using a new theoretical model to determine the association between parenting factors and conduct disorder in Jamaican male adolescents. The issues are discussed within the framework of family, peer group, and biological factors associated with conduct disorder.     

The nature of sexual reinforcement.

Sexual reinforcers are not part of a regulatory system involved in the maintenance of critical metabolic processes, they differ for males and females, they differ as a function of species and mating system, and they show ontogenetic and seasonal changes related to endocrine conditions. Exposure to a member of the opposite sex without copulation can be sufficient for sexual reinforcement. However, copulatory access is a stronger reinforcer, and copulatory opportunity can serve to enhance the reinforcing efficacy of stimulus features of a sexual partner. Conversely, under certain conditions, noncopulatory exposure serves to decrease reinforcer efficacy. Many common learning phenomena such as acquisition, extinction, discrimination learning, second-order conditioning, and latent inhibition have been demonstrated in sexual conditioning. These observations extend the generality of findings obtained with more conventional reinforcers, but the mechanisms of these effects and their gender and species specificity remain to be explored.     

The appeal cycle in early mother-child interaction: nature and implications of a finding from developmental research.

The appeal cycle was observed and delineated through research on mother-child interaction during the second year of life. As a repeated, circumscribed unit of developmental interaction, it is conceived to be an agent of developmental process and psychic structure formation. The appeal cycle has four phases: the adaptational phase, the distress phase, the appeal phase, and the interactional phase. The progression from the adaptational into the distress and appeal phases evidences the child's separation anxiety and failure of self-regulation in response to the experimentally induced attenuation of the mother-child relationship. A successful interactional phase reestablishes the relationship, regulates and restores the child's emotional equilibrium, and enables a return to self-regulation and adaptation. Because the interaction reinforces the functions and structures being developed through identification with the mother, the interactional phase is conceived to be an instrumental event in the mediation of psychic structure formation. The appeal cycle is discussed in comparison with similar phenomena in earlier phases of development and with other studies addressing development during the first two years of life. Directions for future research are noted.     

An S-R inventory of dominance for research on the nature of person-situation interactions1

The development and validation of an S-R inventory of dominance is described. The inventory was found to have high reliability, adequate convergent and discriminant validity, and a meaningful factor structure. In samples of 18 and 164 college students the interaction between persons and situations contributed more to total score variance than did either persons or situations taken separately. Moreover, the percentage of variance due to the person-situation interaction for dominance was found to be substantially larger than those obtained for other personality characteristics that have been studied with S-R inventories. These considerations suggest that this new S-R inventory is particularly appropriate for future research on dominance and the nature of person-situation interactions.     

The sacramental nature of peacemaking rituals: a case for a sacramental spirituality of reconciliation

South African scholar and peace activist John de Gruchy sees a close relationship between sacraments and peacemaking processes. Even though a Protestant, he calls the Church a sacramental community and the Truth and Reconciliation Commission (TRC) a ‘civic sacrament’. This raises the question of the relationship between processes and rituals of peacemaking and sacramentality. Moreover, how does reconciliation, as a core doctrine of Christian theology, relate to sacramentality and peacemaking efforts in society? Is reconciliation sacramental? Hans Boersma’s sacramental ontology provides a theological basis for an affirmative answer. Furthermore, the notion of Christ (and the Church) as primal sacrament(s) (Semmelroth, Schillebeeckx) gives a further basis to see processes of peacemaking as sacramental. The article argues for a sacramental spirituality of reconciliation (Schreiter). However, applying the arguments to two concrete cases, the TRC and the twinning of Coventry and Dresden, shows some difficulties in claiming sacramental status for reconciliation efforts.     

The argumentative nature of holding strong views: A case study

Recently a number of critics of traditional approaches to the study of attitudes have stressed the need to study the ways in which people express views in natural discourse. The present study examines the rhetorical aspects of holding strong views by providing a detailed case study. It focuses on the discourse of a family discussing the British Royal Family, where one member of the family is recognized to hold strong views. A number of rhetorical complexities of the discourse are highlighted and particular attention is placed on the argumentative dimensions of holding strong views. It is suggested that strong views are held in relation to opposing views and in arguing about the issue of monarchy participants are also reflexively arguing about arguments. Examples are given to show that the holder of strong views, as opposed to the holder of weak views, does not necessarily have a greater opposition to the assumption of multisubjectivity, for the discourse of views is paradoxically marked by both assumptions of multisubjectivity and intersubjectivity. It is also shown that the holder of strong views may produce a variable discourse. The rhetorical nature of such variability is discussed and implications are drawn for the study of beliefs and for analysing the relations between thinking and arguing.     

Effects of harsh parenting and positive parenting practices on youth aggressive behavior: The moderating role of early pubertal timing

Prior research indicates that early pubertal timing is associated with aggressive behavior, particularly in the context of adversity as postulated in the contextual amplification hypothesis. However, few studies have examined harsh parenting as the context for the effect of early pubertal timing. Even fewer studies have tested the interactive effect of early pubertal timing and positive parenting on aggressive behavior. In this study, we tested the proposition that early pubertal timing, contrary to the general conception of it as a vulnerability, indexed susceptibility, and thus early maturing individuals were affected more by their environment in a “for better and for worse” manner. The sample consisted of 411 community‐recruited youth aged 11–12 years (51% boys, 80% African Americans). Participants reported Tanner Stages of pubertal development, aggressive behavior and harsh parenting practice of their parents. Puberty scores were standardized with groups of the same age, sex, and ethnicity, and those that scored the top one‐third were defined as early maturing individuals. Parents reported youth's aggressive behavior and their parenting practices towards the youth, including harsh parenting and positive parenting. Early pubertal timing significantly moderated the relationship between harsh/positive parenting and aggressive behavior. Specifically, harsh parenting was positively associated with aggressive behavior to a larger degree among early maturing individuals than among on‐time/late‐maturing individuals. Positive parenting was inversely associated with aggressive behavior but only among early maturing individuals. This study is the first to document support for early pubertal timing as susceptibility to the environmental influences in relation to aggressive behavior. Theoretical and intervention implications are discussed.

     

The nature and methods of learning by doing.

This presentation reviews some of the psychological research on learning by doing and discusses the role that learning-by-doing approaches can play in education and training. It includes a discussion of the author's implementations of this approach and the lessons learned from these implementations. Improved forms of learning by doing now can be supported by information technologies, and there are prospects for extensions to group learning by doing and group learning from examples in the near future.
