The interaction of temporal generalization gradients predicts the context effect

In a temporal double bisection task, animals learn two discriminations. In the presence of Red and Green keys, responses to Red are reinforced after 1-s samples and responses to Green are reinforced after 4-s samples; in the presence of Blue and Yellow keys, responses to Blue are reinforced after 4-s samples and responses to Yellow are reinforced after 16-s samples. Subsequently, given a choice between Green and Blue, the probability of choosing Green increases with the sample duration-the context effect. In the present study we asked whether this effect could be predicted from the stimulus generalization gradients induced by the two basic discriminations. Six pigeons learned to peck Green following 4-s samples (S(+)) but not following 1-s samples (S(-)) and to peck Red following 4-s samples (S(+)) but not following 16-s samples (S(-)). Temporal generalization gradients for Green and Red were then obtained. Finally, the pigeons were given a choice between Green and Red following sample durations ranging from 1 to 16 s. Results showed that a) the two generalization gradients had the minimum at the S(-) duration, an intermediate value between the S(-) and the S(+) durations, and the maximum at the S(+) as well as more extreme durations; b) on choice trials, preference for Green over Red increased with sample duration, the context effect; and c) the two generalization gradients predicted the average context effect well. The Learning-to-Time model accounts for the major trends in the data.     

Integrating Women's Voices and Theory: A Comprehensive Domestic Violence Intervention for Latinas

Using both academic theories and two decades of experience in community, this article presents the work conducted by Caminar Latino (Latino Journey), a comprehensive intervention for Latino families affected by domestic violence. Having developed in both analogous and independent ways from theories in the academic field, Caminar Latino provides a unique opportunity to explore ways in which ecological theory and tenets of feminist therapy can be combined within a social justice framework to address this severe social problem. Of particular relevance to therapists, advocates and others working in this field is the ongoing inclusion of the voices of women participants as a central tenet of the intervention.     

The promise and potential of studying the “invisible hand” of teacher influence on peer relations and student outcomes: A commentary

Peers influence children's social-emotional development and school engagement in important and unique ways. Recent research on peer social networks documents that children are affected by the nature of the school-based peer ecology, as well as by their personal peer experiences. Yet, little is known about how teachers affect the peer ecology, nor how teachers can promote positive peer influences in the school context. The four studies in this special section examine this issue. Together, they document the promise and the potential of studying the “invisible hand” of teacher influence on peer relations, and illustrate the need for further research in this area. This commentary considers the contributions of these papers for conceptualizing processes of transactional teacher and peer influence on student outcomes, and implications for interventions designed to reduce problem behaviors or increase school engagement. In addition, it considers the limitations of current knowledge and directions for future research.     

Negotiating Reintegration and Meanings of Space: Formerly Abducted Youth in Uganda

The war in Northern Uganda has ended, and youth who were abducted by the Lord's Resistance Army continue to return to communities. Research conducted in the summer of 2010 in two locations in Uganda, Gulu and Masindi, shows that the process of reintegration is an ongoing process in which formerly abducted youth (FAY) negotiate social relations for reintegration in a very interactive way. FAY consciously decide to stay quiet about their past to avoid compromising social reintegration. The experience‐oriented approach has allowed for an in‐depth exploration and understanding of the reintegration process from the perspective of FAY. In Northern Ugandan cosmology, meaning given to FAY personal spaces dominates. With FAY facing social exclusion by community members and the need to overcome boundaries to reintegration, coping mechanisms are adopted to facilitate reintegration and to carve out personal space within the Northern Ugandan cosmology. In the exploration of the process of negotiating reintegration, a conceptual model is adopted and adjusted to represent personal space within Northern Ugandan cosmology. The main findings suggest that FAY negotiate social relations for reintegration in a very interactive way and that they consciously decide to stay quiet about their past so as to not compromise social reintegration.

Stigmatised Identity and Service Usage in Disadvantaged Communities: Residents', Community Workers' and Service Providers' Perspectives

The impact of community stigmatisation upon service usage has been largely overlooked from a social identity perspective. Specifically, the social identity‐mediated mechanisms by which stigmatisation hinders service use remain unspecified. The present study examines how service providers, community workers and residents recount their experience of the stigmatisation of local community identity and how this shapes residents' uptake of welfare, education and community support services. Twenty individual and group interviews with 10 residents, 16 community workers and six statutory service providers in economically disadvantaged communities in Limerick, Ireland, were thematically analysed. Analysis indicates that statutory service providers endorsed negative stereotypes of disadvantaged areas as separate and anti‐social. The awareness of this perceived division and the experience of ‘stigma consciousness’ was reported by residents and community workers to undermine trust, leading to under‐utilisation of community and government services. We argue that stigmatisation acts as a ‘social curse’ by undermining shared identity between service users and providers and so turning a potentially cooperative intragroup relationship into a fraught intergroup one. We suggest that tackling stigma in order to foster a sense of shared identity is important in creating positive and cooperative service interactions for both service users and providers.

Presence of meaning and search for meaning as mediators between spirituality and psychological well-being in a South African sample

Spirituality and meaning in life are important pathways to well-being. Research has conceptually and empirically linked spirituality, religiousness and meaning in life. The present study was concerned with investigating presence of meaning (MLQ-P) and search for meaning (MLQ-S) as mediators between spirituality (religious and existential well-being) and hedonic and eudaimonic well-being. A multi-cultural sample of 326 South African students completed the Meaning in Life Questionnaire (MLQ), Spiritual Well-Being Scale (SWBS), Questionnaire for Eudaimonic Well-Being (QEWB) and the Mental Health Continuum Short-Form (MHC-SF). Structural equation modelling in Mplus was used to study direct and indirect effects. Findings show that the presence of meaning in life explains more paths between spirituality and psychological well-being than search for meaning. MLQ-P mediated the paths between existential well-being and four of the five indices of psychological well-being. MLQ-S did not mediate any path between spirituality (existential and religious well-being) and psychological well-being outcomes.     

What is happening in the world of therapeutic communities?

This overview of the contributions to the special edition illustrates something of how the collection of papers reflects the marginal nature of therapeutic communities, and makes parallels as to how they are forever struggling to survive, yet generate a passion of ideas and intellectual resilience that no project-managed health service can extinguish. It briefly describes the theoretical and geographical terrain covered, and signals how the cross-disciplinary incorporation of congruent ideas can be added to the traditional bedrock of therapeutic community practice. It ends by stating the context of the new, and seemingly successful, organization which assembled these contributions into its inaugural conference – and suggests that the journey could, and ultimate should, go further.     

Discomfort in the community. The place of psyche: Between zōē and bios

In this paper, the author considers the treatment of people diagnosed with a psychosis or borderline personality disorder in therapeutic communities from a psychoanalytic perspective, with a particular focus on the work of Jacques Lacan and of André Green. He discusses two key questions. First, how are these patients to recover life? – not just in the biological sense but in terms of subjectivity. Secondly, is it ever really possible to build relationships with them? In relation to this second question, the author emphasizes the importance of the training and supervision of practitioners, as well as their own analysis. Therapeutic communities, above all, he argues, can provide structure and security in a society which is increasingly fragmented and unstable.     

Determinants of ethnic identity development in adulthood: A longitudinal study

Ethnic identity is defined in terms of the interaction between exploration of and commitment to a given cultural background. The present study investigated the effect of individual background, role transitions, and the social environment on the development of ethnic identity in a sample of German adults aged 21–73 years (N = 2,940). Additionally, identity transitions and the moderating effect of disequilibrating life events on identity over time were examined (N = 827). Overall, results are consistent with findings for other identity domains: Respondents could be assigned to one of four identity stages, ranging from unexamined to achieved identity. Particularly, the individual background and the extent of community involvement affected ethnic identity formation in adulthood. Longitudinal analyses revealed that only one-third of respondents had remained in the same identity stage; most individuals had transitioned forward or backward. Changes in ethnic identity were not moderated by disequilibrating life events.     

词语后情绪环境对语义和感知加工的影响

词语后情绪环境对其中的事件记忆产生影响,但是事件后情绪环境如何影响记忆加工仍不清楚。不同的情绪环境理论—“唤醒偏向竞争理论”,“拓宽-建构理论”,“记忆中心的积极情绪促进理论”支持情绪促进的不同本质。已有的研究表明,注意在情绪记忆中有重要作用。实验一、实验二分别探讨词语后情绪环境对其语义加工与内源源加工和外源源加工的影响。与中性环境相比,积极与消极情绪环境阻碍了外源源特征的加工; 与中性环境和积极情绪环境相比,消极情绪环境阻碍了内源源特征的加工。实验结果支持“唤醒偏向竞争理论”,同时表明“评估”和“注意放置”在情绪环境影响中的重要作用。
