Body displacement, the theory that predicts that individuals with eating disorders will displace negative feelings about themselves onto their body, was tested experimentally in this study. Unrestrained eaters (n = 61), restrained eaters (n = 33), and individuals with eating disorders (n = 26) were randomly assigned to a control condition or an ineffectiveness induction. In the ineffectiveness condition participants were asked to recall and reflect on a past experience when they felt useless or incapable (i.e., ineffective). Results showed that individuals with eating disorders who were made to feel ineffective reported more implicit appearance/body concern than those in the control condition. Unrestrained and restrained eaters did not show this effect. This is the first experimental study to support body displacement theory. These data can be used clinically to educate and encourage patients with eating disorders to address thoughts and feelings related to ineffectiveness directly, instead of displacing this distress onto their body and potentially perpetuating their eating disorder. 相似文献

暴食症已成为目前世界上广泛流行的三大进食障碍之一,我国患者亦不在少数并有增加之势,但对暴食症的研究与治疗尚属起步阶段。文章回顾了暴食症的表征及其诊断技术,简要介绍了常见的三种治疗方法(即行为疗法、认知疗法及伴随症状改善法),并讨论了影响暴食症疗效的诸个体因素。暴食症的诊断主要是根据美国精神疾病诊断与统计手册第四版(DSM-IV)、进食障碍检测评估表(EDE)(治疗者用)和患者用进食障碍检测问卷(EDE-Q)(患者用),并结合过往病史和伴随症状。三类治疗方法在理论与操作层面各有倚重,均可收到一定治疗效果。但各疗法的效果与预后会因患者而异甚或迥乎相异,这是因为暴食症疗效还受到患者自身人格、社会和认知诸因素的影响,治疗者应根据特定患者选择适合该患者的疗法。 相似文献

立体视觉的心理物理和VEP比较研究 总被引:2,自引:0,他引:2
心理物理试验是研究立体视觉的主要方法。70年代VEP开始用于体视研究,并取得许多结果。由于VEP信号复杂,这些结果不能令人满意。本文使用心理物理试验和VEP对比方法对体视加以研究。我们的结果是:VEP波形中第一个正峰与刺激图形的亮度有关;N_2峰和P_3峰的潜伏期对判断体视存在与否有重要价值;本试验确定N_2峰潜伏期在体视存在时约为240ms—280ms,无体视存在时约为290ms—310ms;P_3峰潜伏期在体视存在时约为280ms—310ms,无体视存在时约为340ms—360ms;体视存在时的VEP与无体视存在时的VEP的互相关系数小于0.1;有体视的VEP其功率谱密度在8Hz附近有一峰;心理物理试验中使用强制选择得到的结果从VEP波形比较中可以确认是可靠的;有体视的VEP其N_2和P_3的潜伏期随视差变化呈现规律性改变。 相似文献

This study evaluated video scoring and feedback about scoring as a safety intervention among 6 nursing staff. The dependent variable was safety behavior on one‐person transfers. Following baseline, 5 nursing staff participated in an information phase. A video scoring phase was then introduced for all 6. A feedback phase was added for 2 participants. All participants experienced treatment withdrawal. Information resulted in improvements for all 5 participants who received it. Further improvements were observed during video scoring for the 5 participants who improved following information. No improvements were observed for the participant who received only video scoring. Safety feedback further improved safety for the 2 participants who received it. However, participants' behavior returned to video scoring levels during withdrawal. 相似文献

自闭症谱系障碍(ASD)是一种心理状况的谱系障碍,其症状是社交及沟通上的广泛性异常、异常局限性的兴趣和高度重复性的刻板行为。包括自闭症、亚斯伯格症候群和待分类的广泛性发展障碍3类。研究主要以事件相关电位和功能性磁共振成像两种技术为线索,通过深入分析ASD患者在面孔识别认知过程中脑的异常变化,探讨其面孔识别障碍的神经机制问题。研究表明,ASD患者面孔识别能力的损伤主要与N170、N300、P400和Nc等ERPs成份异常及梭状回面孔区和杏仁核的低激活有关。研究推论ASD患者面孔识别障碍是多个异常脑区联合作用的结果,且主要受异常脑区的数量和损伤程度的影响。 相似文献

Resource-limited regions of the world represent the areas most affected by the global HIV epidemic. Currently, there are insufficient
data on the neurocognitive effects of HIV in these areas and neuropsychological studies that have been carried out thus far
are marked by inconsistent methods, test batteries, and rating systems for levels of cognitive impairment. These differences
in methods, along with genetic variability of both virus and host, differences in co-infections and other co-morbidities,
differences in language and culture, and infrastructural deficiencies in many international settings create challenges to
the assessment of neurocognitive functioning and interpretation of neuropsychological data. Identifying neurocognitive impairment
directly attributable to HIV, exploring relationships between HIV-associated neurocognitive impairment, disease variables,
and everyday functioning, evaluating differences in HIV-1 subtype associated neuropathology, and determining implications
for treatment remain complicated and challenging goals. Endeavors to establish a more standardized approach to neurocognitive
assessments across international studies in addition to accumulating appropriate normative data that will allow more accurate
rating of neuropsychological test performance will be crucial to future efforts attempting to achieve these goals. 相似文献

Anger has a prominent role in basic theories of emotion. And while many psychiatric disorders can be conceived of as emotional
disorders (e.g., depressive disorders, anxiety disorders), there are no disorders for which anger is the cardinal feature.
We analyzed diagnostic data on 1,687 (as later) psychiatric outpatients and looked at the co-occurrence of high trait anger
(as assessed by criterion 8 of Borderline Personality Disorder) and Axis I disorders, and Borderline and Antisocial Personality
Disorders. The purpose was to examine whether dysfunctional anger met criteria necessary to be considered a valid diagnostic
category. Results showed that high trait anger was not fully accounted for by any particular Axis I diagnosis, or any set
of Axis I diagnoses, or by the combination of Axis I diagnoses and Borderline and Antisocial PDs. Trait anger also accounted
for significant amounts of unique variance in several indicators of psychiatric impairment and psychosocial functioning. We
describe the anger disorder diagnoses of Eckhardt and Deffenbacher (Anger disorders: Definition, diagnosis and treatment.
Taylor & Francis, Bristol, PA, 1995), and discuss the implications of those diagnoses for the practice of REBT and CBT.

We analyzed family dynamics and coping behaviors of parents with a child with an autistic spectrum disorder. Previous research
suggests that moderate levels of cohesion and adaptability are associated with higher levels of positive coping, and that
the more coping strategies a family implements, the greater their satisfaction with family functioning. Using a family systems
approach, the relationships among the familial variables of cohesion, adaptability, and social support were evaluated for
their contributions to coping in the family unit. We also compared the responses of mothers and fathers. Surprisingly, for
these parents of children with autism, those who rated their family as enmeshed implemented more positive coping strategies
than did those from other cohesion styles. This finding suggests that the enmeshed style may be more adaptive for a family
that encounters extreme challenges. Notably, mothers and fathers agreed on all variables except for perception of social support
from family and friends. Mothers perceived more social support from family and friends. The results lead to several interesting
suggestions for future research. 相似文献

Disruptions to hypothalamic-pituitary-adrenal (HPA) axis function have been associated with varying forms of psychopathology
in children. Studies suggesting children with ADHD have blunted HPA function have been complicated by the prevalence of comorbid
diagnoses and heterogeneity of ADHD. The goals of this research were to assess the relations between waking and stress–response
salivary cortisol levels and comorbid disruptive behavior (DBD) and anxiety (AnxD) disorders and problems in boys with ADHD,
and to examine whether cortisol levels varied across ADHD subtypes. One hundred seventy elementary school-age boys with ADHD
provided salivary cortisol at waking and in reaction to venipuncture. Parent reports were used to assess boys’ psychiatric
diagnoses and severity of behavioral problems. Boys’ comorbid AnxD and anxiety problems were associated with greater cortisol
reactivity, whereas boys’ comorbid DBD and oppositional problems predicted diminished adrenocortical activity. Reactive cortisol
increases were greatest in boys with ADHD and comorbid AnxD, but without DBD. ADHD subtypes were not differentially associated
with waking, pre-stress baseline, or reactive cortisol levels. However, comorbid DBD predicted decreased cortisol reactivity
in boys with inattentive and hyperactive subtypes of ADHD, but not in boys with combined subtype of ADHD. The results clarify
previous patterns of distinct and divergent dysregulations of HPA function associated with boys’ varying kinds of psychopathology.
