接触干预在减少精神障碍公众污名中的应用

接触干预是减少精神障碍公众污名的重要方式之一。不同接触形式已被广泛应用在减少公众污名的干预研究中, 且被证实在态度、情感、行为倾向等方面均能有效减少污名。接触干预的效果受到干预实施过程和干预对象特点两方面影响。从干预实施过程来看, 有效接触干预包含精神障碍患者、信息和互动三个关键成分, 这些成分需要具备一定特点才能产生效果; 同时, 多形式接触、连续接触、接触质量等成分的存在能够进一步扩大接触干预效果。从干预对象来看, 接触干预效果会随着干预对象的个体差异而有所不同。未来的研究需要进一步完善接触干预的研究设计, 丰富接触干预的理论机理研究, 推动接触干预的循证实践发展。同时, 应用接触干预减少特定群体公众污名, 以及干预特定精神障碍类型公众污名是进一步研究方向, 并在我国文化背景下进一步检验接触干预效果。     

The Relative Effects of Abstract Versus Concrete Processing on Proactivity in Depression

Low levels of proactivity are characteristic of individuals with depression. Two studies were conducted to compare the relative effects of abstract versus concrete processing on proactivity in high dysphoric individuals. In Study 1, participants read information about an upcoming research study and were then randomly allocated to a writing task that induced them to think about participating in that study in either an abstract (e.g., Why you would participate in the study?; n = 25) or concrete (e.g., How you will participate in the study?; n = 25) way. Participants were then asked to indicate whether they would sign up to the study. As expected, more participants indicated that they would take part in the study in the concrete condition (76%) than in the abstract condition (36%). In Study 2, high dysphoric participants were asked to identify their ideal part-time job and were then randomly allocated to a writing task that induced them to think about applying for the job in an abstract (n = 26) or concrete (n = 25) way. There was no difference between conditions in self-reported intentions of proactivity. However, significantly more participants in the concrete condition opted to look at an employment assistance website and returned to the lab to collect a job application package. Overall, these findings suggest that abstract processing could contribute to low levels of proactivity in depression, and that facilitating the use of concrete processing could help to alleviate this problem. Our results also point to the need for greater conceptual clarification of the distinction between concrete processing about proactive behavior and implementation intentions (identifying specific steps for completing an action/goal).     

Sustainable Masculinity in Ecumenical Perspective

Gender is an important topic of the WCC's Pilgrimage of Justice and Peace. It is the result of both theological anthropological concerns and the ongoing search for justice and peace. In other words, it is a typical area where traditional Faith and Order and Life and Work concerns coincide. Yet, gender is often taken to mean concerns of the role, rights, and treatment of women primarily, with some attention to the position and treatment of transgender persons and sexual minorities. This article argues that, precisely from the point of view of these ecumenical theological concerns, attention for masculinity as a gender is also required. The reason for this is that although many different forms of masculinity are supported with an appeal to the Christian tradition, not all forms of masculinity are compatible with a desire for safeguarding human dignity and a sustainable journey into the future.     

Is Intrinsic Value Conditional?

Accoding to G.E. Moore, something's intrinsic valuedepends solely on its intrinsic nature. Recently Thomas Hurka andShelly Kagan have argued, contra Moore, that something's intrinsic valuemay depend on its extrinsic properties. Call this view the ConditionalView of intrinsic value. In this paper I demonstrate how a Mooreancan account for purported counterexamples given by Hurka and Kagan. I thenargue that certain organic unities pose difficulties for the ConditionalView.

The fragile X syndrome: from molecular genetics to neurobiology

Since the identification of the FMR1 gene basic research has been focused on the molecular characterization of the FMR1 gene product, the fragile X mental retardation protein (FMRP). Recent developments in fragile X research have provided new insights and knowledge about the physiological function of FMRP in the cell and the nerve cell in particular. Currently, compelling evidence suggests a role for FMRP in the transport/translation of dendritically localized mRNAs. In addition, the identification of some of the target mRNAs of FMRP have led to an increased interest in the neurobiology of the syndrome. This review highlights the role of FMRP in dendritic mRNA transport/translation in relation to synaptic plasticity, a molecular mechanism implicated in learning and memory.     

Kenneth B. Clark in the patterns of American culture

Kenneth B. Clark is most well-remembered as the social scientist cited by the U.S. Supreme Court in footnote 11 of its decision in Brown v. Board of Education in 1954. His presence in that decision came to symbolize the role that social science could play in changing social policy and public attitudes. As an African American social scientist who was prominent during a time of great turmoil over racial issues in the United States, Clark also became a "participant-symbol" in America's discussion of race. Clark contributed to this discussion in the three books he wrote for the general public: Prejudice and Your Child (Clark, 1955), Dark Ghetto (Clark, 1965), and Pathos of Power (Clark, 1974). In this article, the author discusses how these works document Clark's growing pessimism about the prospects for improving race relations. In addition, Clark's place in contemporary American debates about Brown v. Board of Education and the persistence of racial equality is considered.     

The effect of spectral manipulations on the identification of affective and linguistic prosody

We investigated the effect of various spectral manipulations on the identification of sentential prosody. Two main categories of prosody--affective (happy, angry, sad) and linguistic (statement, question, continuation)--were studied. Thirty-six subjects were presented with stimuli that were recorded by a female native speaker of American English. The stimuli were digitally manipulated to create synthesized, band-pass filtered (F0-range and F2/F3-range) and re-entrant (pitch only version of stimulus is convolved with a steady-state signal) conditions. Results of a forced-choice discrimination paradigm showed that, in general, performance is remarkably robust despite spectral manipulation, even when there is relatively little spectral information. However, performance was significantly degraded in the low band-pass and re-entrant conditions. These observations are discussed in light of the relevance of the fundamental frequency as well as syllabification for the analysis of prosodic information.     

Arousal, changeover responses, and preference in concurrent schedules

Pigeons were trained on multiple schedules that provided concurrent reinforcement in each of two components. In Experiment 1, one component consisted of a variable-interval (VI) 40-s schedule presented with a VI 20-s schedule, and the other a VI 40-s schedule presented with a VI 80-s schedule. After extended training, probe tests measured preference between the stimuli associated with the two 40-s schedules. Probe tests replicated the results of Belke (1992) that showed preference for the 40-s schedule that had been paired with the 80-s schedule. In a second condition, the overall reinforcer rate provided by the two components was equated by adding a signaled VI schedule to the component with the lower reinforcer rate. Probe results were unchanged. In Experiment 2, pigeons were trained on alternating concurrent VI 30-s VI 60-s schedules. One schedule provided 2-s access to food and the other provided 6-s access. The larger reinforcer magnitude produced higher response rates and was preferred on probe trials. Rate of changeover responding, however, did not differ as a function of reinforcer magnitude. The present results demonstrate that preference on probe trials is not a simple reflection of the pattern of changeover behavior established during training.
