The effect of unpredictable, inescapable and uncontrollable electric tail shocks (ES) on the humoral immune response to bovine serum albumin (BSA) was investigated in the rat. Contributions of the procedures that accompany shock delivery, such as witnessing the ES procedure (stress witnessing, SW) and exposure to the apparatus for shock delivery (apparatus control, AC) to the changes in specific immunity induced by ES were also tested. All procedures were applied during primary and/or secondary immunization. It was demonstrated that exposure to ES during primary immunization with BSA significantly suppressed specific anti-BSA antibody production after secondary and tertiary immunization with the same antigen. Exposure to the SW procedure during primary immunization with BSA enhanced the specific antibody level after secondary immunization, while exposure to the apparatus alone did not influence the development of either the primary or secondary humoral immune response to BSA. Both ES-induced suppression and SW-induced potentiation of the humoral immune response were partially inhibited by prior treatment with the opioid receptor antagonist naloxone. Additionally, treatments with the opioid peptides methionine- and leucine-enkephalin decreased anti-BSA antibody level, mimicking to some extent the effects of ES. It is suggested that ES and endogenous opioid peptides had long-term effects on humoral immunity through mechanisms involving immunologic memory.  相似文献

This article provides a critical review of the literature on research with self-report measures of depression and anxiety in East Asia. Three trends are noteworthy. First, research on depression and anxiety in East Asia has relied heavily on the use of a limited number of translated instruments. Second, available research suggests that the Asian language versions of these instruments are reliable and valid for use with Asian populations. Third, some subpopulations in East Asia have been studied extensively with respect to depression and anxiety, but there are many regions of Asia where little research literature is available outside of those published in native language journals. The review concludes with recommendations for future research.  相似文献

In two experiments, we examined Safer, Christianson, Autry, and Osterlund's (1998) claim that when emotional material is remembered, tunnel memory (i.e., the tendency to remember less of a scene than was actually shown) occurs. In Experiment 1, 81 undergraduate students drew photographs from memory after having briefly seen either four neutral or four emotional photographs. Both neutral and emotional drawings revealed boundary extension (i.e., the tendency to remember more of a scene than was actually shown). Experiment 2 relied on the camera distance paradigm (Intraub, Bender, & Mangels, 1992). In a recognition test, 60 undergraduate students judged the camera distance of previously seen neutral or emotional photographs. The majority of them demonstrated accurate judgments and neither extended nor restricted picture boundaries. Those participants who made an error more often displayed a boundary extension than a tunnel memory error. Taken together, our results suggest that boundary extension for neutral and emotional photographs is a more robust phenomenon than its counterpart, tunnel memory.  相似文献

Both cross-sectional and longitudinal studies in the United States have shown consistent changes between college age and middle adulthood. There appear to be declines in 3 of the 5 major factors of personality--Neuroticism, Extraversion, and Openness--and increases in Agreeableness and Conscientiousness. To examine cross-cultural generalizability of these findings, translations of the Revised NEO Personality Inventory were administered to samples in Germany, Italy, Portugal, Croatia, and South Korea (N = 7,363). Similar patterns of age differences were seen in each country, for both men and women. Common trends were also seen for the more specific traits that define the major factors. Because these nations differ substantially in culture and recent history, results suggest the hypothesis that these are universal maturational changes in adult personality.  相似文献

Western scholarship has underlined the relevance of social identity, perceived efficacy, emotions, and cost–benefit assessments as central catalysts of collective action. Little has been done to understand the context-sensitivity of these catalysts by means of cross-culturally comparative designs. The current study explores their context-sensitivity. It aims to find out whether existing opportunity structures in a democratic, nonrepressive country like Germany produce catalysts of collective action different from those produced in an autocratic, repressive country like Turkey. It also aims to understand the role of social media in mobilizing people in these two contexts. Semistandardized interviews with activists were carried out in both countries (n = 18 in Germany and n = 15 in Turkey) and analyzed by means of a cross-culturally comparative inductive coding procedure including initial and focused coding. Results show that collective action is related to different configurations of collective-action catalysts in the two countries. Solidarity concerns at the face of existential risks are more pronounced in Turkey, whereas political-change concerns are more important in Germany. The role of social media accordingly differs, adhering to the different activist goals. Theoretical implications for the role of context in studying collective action are discussed.  相似文献

In this article a specific type of narrative, which often appears in analytic sessions, is discussed. It is characterized by a seemingly ordinary, everyday topic and by a peculiar disruption of the narrative flow. The threefold structure of this type of narrative is described, along with its main characteristics. One element of this type of narrative is very similar to symbolic content or complex symbolic structures, e.g. dreams, the sort of material that can be used for the purpose of interpretation. The similarities as well as the differences are elaborated in the article. Thanks to the observed general structure and ‘symbolic’ nature of some parts of the narrative, it is easy to notice some of the unconscious elements, which are not familiar to the patient's ego, and to make an interpretation. Because these elements are close to the threshold of consciousness, the patient willingly accepts an interpretation based on them. This is especially true for patients whose dominant function is thinking. A temporary, working name for this type of narrative is proposed in the article: ‘disrupted narrative ? and for its disruptive part ‘narrative symbol’.  相似文献

This paper offers a short analysis of the ecclesiological and missiological context that led to the establishment of the Romanian Pentecostal Agency for Foreign Mission (APME). It states the main steps in the process of the development of the organization in its first decade of existence (2006–2016), during which it became one of the youngest and most dynamic missionary structures in Europe. It describes the process of the birth of APME and the important role the founding team played in the existence of the agency and in articulating the mission, vision, values, and work philosophy. The main section will present the components of APME's work strategy which led to implementing the vision and reaching the objectives: mobilizing the churches, recruiting, training, sending, supporting missionaries, and promoting the ministry. A short section will show the crucial importance of internal and foreign partnerships in the activity of APME. In the final part we will list the main lessons learned in the ten years of APME's existence that can be shared with other mission organizations, as well as the challenges that the organization faces over the next few years.  相似文献

Little longitudinal research has examined progression to more severe bipolar disorders in individuals with "soft" bipolar spectrum conditions. We examine rates and predictors of progression to bipolar I and II diagnoses in a nonpatient sample of college-age participants (n = 201) with high General Behavior Inventory scores and childhood or adolescent onset of "soft" bipolar spectrum disorders followed longitudinally for 4.5 years from the Longitudinal Investigation of Bipolar Spectrum (LIBS) project. Of 57 individuals with initial cyclothymia or bipolar disorder not otherwise specified (BiNOS) diagnoses, 42.1% progressed to a bipolar II diagnosis and 10.5% progressed to a bipolar I diagnosis. Of 144 individuals with initial bipolar II diagnoses, 17.4% progressed to a bipolar I diagnosis. Consistent with hypotheses derived from the clinical literature and the Behavioral Approach System (BAS) model of bipolar disorder, and controlling for relevant variables (length of follow-up, initial depressive and hypomanic symptoms, treatment-seeking, and family history), high BAS sensitivity (especially BAS Fun Seeking) predicted a greater likelihood of progression to bipolar II disorder, whereas early age of onset and high impulsivity predicted a greater likelihood of progression to bipolar I (high BAS sensitivity and Fun-Seeking also predicted progression to bipolar I when family history was not controlled). The interaction of high BAS and high Behavioral Inhibition System (BIS) sensitivities also predicted greater likelihood of progression to bipolar I. We discuss implications of the findings for the bipolar spectrum concept, the BAS model of bipolar disorder, and early intervention efforts.  相似文献
