条件反射性免疫抑制激活过程中下丘脑核团c-fos的表达

利用经典条件反射性免疫抑制的动物模型,以糖精水为条件刺激（CS）,免疫抑制剂-环磷酰胺为非条件刺激 （UCS）,观测两次CS-UCS结合训练后,再次条件刺激诱发条件反射性免疫抑制作用的动态改变,获得条件反射性免疫抑制和味觉厌恶性条件反射各自保持的情况,并在此基础上,采用c-fos免疫组化技术, 进一步观察再次条件刺激诱发条件反射性免疫抑制反应时大鼠下丘脑各核团内FOS蛋白的表达情况。结果表明,条件反射性免疫抑制作用在训练后第5天较强,第30天基本消失,而味觉厌恶性条件反射始终稳定保持到第30天。进一步研究显示出,下丘脑室旁核FOS蛋白表达在第5天非常密集,而第30天几乎没有表达,与细胞免疫功能改变在时程和趋势上具有一致性。通过FOS蛋白表达时程差异比较,提示下丘脑室旁核可能是CNS内介导CS诱导的免疫抑制效应的重要核团。     

Excitotoxic lesions of the parafascicular nucleus produce deficits in a socially transmitted food preference

The parafascicular (PF) nucleus, a posterior component of the intralaminar nuclei of the thalamus, is considered to be an essential structure in the feedback circuits of basal ganglia-thalamo-cortical systems that critically participate in cognitive processes. To study the PF contribution to processing of behaviorally significant information during specific episodes of learning, we investigated the effects of damaging the PF nucleus in the acquisition of a natural form of social olfactory learning, the socially transmitted food preference (STFP) task. This task is a non-spatial paradigm that exhibits some of the characteristics of relational memory because it requires that animals use information obtained in one episode to guide later behavior in different circumstances. Adult male Wistar rats were submitted to pretraining bilateral N-methyl-D-aspartate (0.15 M, pH 7.4) lesions of the PF (0.4 microl/side, 0.2 microl/min). The behavioral effects of PF lesions were compared to vehicle- and sham-operated control groups and two retention delays were considered in separate groups: immediately (Lesion-I, Vehicle-I, and Sham-I groups) and 24h after training (Lesion-24, Vehicle-24, and Sham-24 groups). PF lesions produced delay-independent impairments in the STFP suggesting that this nucleus might modulate the acquisition of this odor-odor association task. Results are discussed in the context of medial prefrontal cortex deafferentation induced by PF damage.     

The deep student: A thematic analysis of counsellor educators' perceptions and experiences

What does it mean when we say a person is “deep” or has a lot of “depth?” We asked counsellor educators to describe the concept of personal depth, how it manifests in counsellors' work, and whether or not it could be trained. Twenty counsellor educators responded, and we analysed their responses using thematic analysis. We unearthed seven major themes of the construct: nondual consciousness, emotions, cognitions, interpersonal attributes, self-awareness, attitude and life experiences. Participants also provided suggestions for training students to cultivate personal depth. Finally, we introduce a depth wheel to conceptualise our results and provide implications for counselling and training.

The Purist/Partisan Spectator Discourse: Some Examination and Discrimination

ABSTRACT

The spiralling discourse of sport spectatorship is a compelling development within recent sport philosophy. It is argued that the conceptual foundations of the purist and partisan carry problems. The purist carries the dubious baggage of traditional aesthetics and should be supplanted by the aesthetically neutral cognoscente. The partisan, especially as unpacked by Mumford, is a chimera. Partisanship contains a regard for the excellences of the practice within its own logic. It is argued also that Mumford’s picture of ‘frenetic’ partisanship and ‘tranquil’ purism is over-dichotomised and that partisan response to opposition excellence, and to the plays of one’s own side, is nuanced according to context. The essay also proposes the new concept of the deep partisan, who has a deep and heavily cognitivised love of his club and an intimately connected equivalent love of the excellences of the practice.     

Happy Danes and Deep Incarnation

The new Copenhagen School of Deep Incarnation posits that, in Jesus Christ, God has become incarnate and therefore present “in, with, and under” all physical and biological processes. This claim raises the issue of “compatibilism,” according to which divine action and creaturely action are compatible, and “incompatibilism,” according to which divine action must be absent to allow for free creaturely action. Niels Henrik Gregersen, representing the Copenhagen School, affirms both compatibilism at the quantum level of physical activity and incompatibilism at the level of nature's self‐organization. This article points out the incoherence of this position along with the positions proffered by process theologians and kenotic theologians.     

Poor motor skills: A risk marker for bully victimization

Children who are clumsy are often bullied. Nevertheless, motor skills have been overlooked in research on bullying victimization. A total of 2,730 Swedish adults (83% females) responded to retrospective questions on bullying, their talents in physical education (i.e., coordination and balls skills) and school academics. Poor talents were used as indicators of poor gross motor skills and poor academic skills. A subset of participants also provided information on educational level in adulthood, childhood obesity, belonging to an ethic minority in school and socioeconomic status relative to schoolmates. A total of 29.4% of adults reported being bullied in school, and 18.4% reported having below average gross motor skills. Of those with below average motor skills, 48.6% were bullied in school. Below average motor skills in childhood were associated with an increased risk (OR 3.01 [95% CI: 1.97–4.60]) of being bullied, even after adjusting for the influence of lower socioeconomic status, poor academic performance, being overweight, and being a bully. Higher odds for bully victimization were also associated with lower socioeconomic status (OR 2.29 [95% CI: 1.45–3.63]), being overweight (OR 1.71 [95% CI: 1.18–2.47]) and being a bully (OR 2.18 [95% CI: 1.53–3.11]). The findings indicate that poor gross motor skills constitute a robust risk‐marker for vulnerability for bully victimization. Aggr. Behav. 39:453–461, 2013. © 2013 The Authors.

Retention of word pairs as a function of level of processing,instruction to remember,and delay

ABSTRACT

Modern research on the efficacy of levels of processing (LoP) tasks on memory has focused on less than 1-day retention delays, while assuming that the observed benefits of deep tasks will continue across remote delays. However, direct tests of the continued benefits of deep processes for accuracy and organisation in remote memory are rare. The current set of experiments, using auditorily-presented lists of scrambled word pairs, tested whether deep LoP tasks produced better free recall and organisation over one week (Experiment 1) and four weeks (Experiments 2 and 3). All experiments revealed significant LoP effects on free recall and organisation at immediate and delayed test, with no effect of intention to remember. However, Experiments 2 and 3 revealed poor recall and organisation at the delayed tests among all of the LoP groups, suggesting that deep processing may not produce highly accessible memories over very long delays.     

A better state-of-mind: deep breathing reduces state anxiety and enhances test performance through regulating test cognitions in children

A pre-test/post-test, intervention-versus-control experimental design was used to examine the effects, mechanisms and moderators of deep breathing on state anxiety and test performance in 122 Primary 5 students. Taking deep breaths before a timed math test significantly reduced self-reported feelings of anxiety and improved test performance. There was a statistical trend towards greater effectiveness in reducing state anxiety for boys compared to girls, and in enhancing test performance for students with higher autonomic reactivity in test-like situations. The latter moderation was significant when comparing high-versus-low autonomic reactivity groups. Mediation analyses suggest that deep breathing reduces state anxiety in test-like situations, creating a better state-of-mind by enhancing the regulation of adaptive-maladaptive thoughts during the test, allowing for better performance. The quick and simple technique can be easily learnt and effectively applied by most children to immediately alleviate some of the adverse effects of test anxiety on psychological well-being and academic performance.
