Histrionic Personality Disorder, Physical Attractiveness, and Social Adjustment

Histrionic personality disorder (HPD) is the only DSM-IV personality disorder (PD) explicitly linked to a person's physical appearance. This study examined the HPD–attractiveness link in a mixed-sex sample of college students. Consistent with expectations, HPD women were rated higher in attractiveness than women with other PDs or no PD. However, a parallel HPD–attractiveness link was not found in men. Subsequent analyses indicated that, relative to less attractive HPD women, more attractive HPD women (a) had a more varied and supportive social network, (b) exhibited more negative behaviors in important relationships, and (c) showed greater use of immature defenses, and less reliance on image-distorting, self-sacrificing, and mature defenses. Similar attractiveness–defense relationships were found in HPD men, but parallel results did not emerge for men in the other two domains. Implications of these findings are discussed, and suggestions for future studies are offered.     

STIMULUS FADING AS TREATMENT FOR OBSCENITY IN A BRAIN-INJURED ADULT

Obscene verbalizations of a person with traumatic brain injury were treated using stimulus fading as the singular form of intervention. Results of a functional assessment revealed that obscenity was maintained by negative reinforcement. Stimulus fading (initial elimination of instructional demands followed by their gradual reintroduction) produced immediate and substantial reductions in obscenity that were maintained as the frequency of demands increased to baseline levels. Potential applications of the use of antecedent treatment strategies are discussed.     

Synergistic effects of ethanol and cocaine on brain stimulation reward.

The effects of two widely abused drugs, ethanol and cocaine, were examined alone and in combination on intracranial reward processes. In agreement with previous research, higher doses of both cocaine and ethanol alone produced facilitation of behavior maintained by brain stimulation reward. Low intraperitoneal doses of ethanol and cocaine, which alone did not affect performance, were found to reduce stimulation reward threshold and modestly increase response rate. The enhancement of brain stimulation reward by the combination of ethanol and cocaine suggests that both drugs may produce their rewarding effects through common neuronal substrates and that they may potentiate the abuse of each other.     

A GROUP-ORIENTED CONTINGENCY TO INCREASE LEISURE ACTIVITIES OF ADULTS WITH TRAUMATIC BRAIN INJURY

An interdependent group-oriented contingency and graphic feedback were used to increase the activity levels of residents of a group home for persons with traumatic brain injury. Results showed that the intervention was effective for 4 of the 6 subjects. Individual performances must be examined when implementing group contingencies because all subjects may not respond.     

Child protection investigations: Discourse analysis and the management of incommensurability

This paper asks whether discourse analytic approaches in social psychology have yet produced methodologies adequate to the investigation of institutional ‘gaze’. Institutional language has been explored to the extent that state agencies construct members of the public by speaking about them in particular ways. This has often provided insight into the co-existence and competition of incommensurable discourses. However, studies of representation in the sense of speaking for have been notably absent from social psychology. It is argued that this aspect of discourse is a vital component in the study of contemporary governmental multi-agency strategy in the area of child protection, where recent legislation and policy aims at the coordination of incommensurable discourses. A methodology for studying this strategy is outlined through an account of the actor network approach in science studies, accounts of the State under the post-modern condition, and analyses of sections of interviews with social workers.     

Involvement of reactive oxygen species in emotional stress: A hypothesis based on the immobilization stress-induced oxidative damage and antioxidant defense changes in rat brain,and the effect of antioxidant treatment with reduced glutathione

We examined the oxidative damage and antioxidant defense changes with immobilization-induced emotional stress in the rat brain. Though superoxide dismutase activity remained unchanged, brain peroxidation was significantly accelerated by the immobilization stress. Membrane fluidity study with spin labeling in brain cortical membrane showed that immobilization stress induced an increase in microviscosity of membrane layer near the surface and in the ordering of membrane proteins but a decrease in microviscosity at the core of the membrane bilayer. The Na, K-ATPase activity decreased whereas the levels of some monoamines and their metabolites increased along with their metabolic rate. The administration of reduced glutathione showed a protective effect on the immobilization stress-induced stomach bleeding, oxidative damage and abnormal changes in the brain antioxidant defenses. Based on these results and on previous reports, we hypothesize that immobilization stress may induce the formation of reactive oxygen species which weakens the brain antioxidant defenses and induces oxidative damage. The antioxidant administration of reduced glutathione provides further evidence to support the above hypothesis, and also may provide clues in the search for a rational therapy to emotional stress. A possible correlation of emotional stress to aging is also discussed.     

Histological data: Hollard and Davison (1971)

As Mogenson and Cioé (1977) have assumed that our electrodes aimed at the ectostriatum (Hollard and Davison, 1971) were actually located there, we feel that a presentation of the histological data is necessary. Following termination of further experiments (Hollard, 1974) the pigeons, numbered 93, 95, and 119, were sacrificed and perfused with saline followed by 10% formalin. Sections, 50 microns thick, were cut on a freezing microtome. Prints were made by mounting each unstained section of a microscope slide and placing them in a standard photographic enlarger. The electrode tips of Pigeons 93 and 119 were located in the paleostriatal complex. The sections of Pigeon 95 were damaged and precise localization was not possible. Further work in this laboratory has also found that, using the same coordinates, electrode tips tend to fall in the paleostriatum, rather than in the more dorsal ectostriatum at which they are aimed. The paleostriatal placements tended to sustain self-stimulation, whereas others located in the ectostriatum sustained relatively low or unstable rates.     

柯林斯语义层次网络模型的实验研究

应用语义验证法对柯林斯与奎利安的语义层次网络模型进行研究,结果表明:(1)柯林斯等人的语义层次网络模型不完全适用于人脑的信息加工;(2)被试对主语所指称客体的熟悉程度是决定语义验证时间的一个重要因素;(3)被试提取概念各属性的时间并非完全由属性储存的位置决定的。     

Clinicians and supervisors' experiences with developing practices of open dialogue in network meetings in public mental health services

Open Dialogue is a dialogical approach focusing on the perspectives of patients and their social networks on treatment and recovery processes. As part of a larger research project, this prospective cohort study explores what promotes and hinders the development of Open Dialogue in network meetings (ODNM) based on the experiences of thirty-seven clinicians and seven supervisors. Multistage focus group interviews were used to collect data and were analysed thematically. We generated two main themes: (1) togetherness and isolation and (2) challenging and evolving. The findings show that ODNM can be developed in public mental healthcare, but this leads to both challenges and opportunities at the organisational level, such as conflicting perspectives, the difficulty of maintaining interest in ODNM, the need for committed and involved leaders, and the growing change in the traditional view of treatment, which has made clinicians collaborate more with patients and their relatives.     

睡眠剥夺与购物后悔：来自大规模个体层面数据的证据

睡眠剥夺正在成为人们面临的一种普遍问题,但是已有研究很少将睡眠剥夺与消费者行为联系起来。本文采用真实购物情境下的大规模消费者个体层面数据(N=1625472),通过建立计量经济学模型来研究睡眠剥夺与购物后悔的关系。结果表明,睡眠剥夺显著地增加了消费者的购物后悔倾向,具体在行为上表现为增加了商品的退货概率和加快了商品的退货速度。此外,商品的价格正向调节了睡眠剥夺对购物后悔的影响,而促销优惠金额的比例则负向调节了睡眠剥夺对购物后悔的影响。
