温尼科特的精神分析客体关系理论的治疗观

温尼科特是英国精神分析客体关系学派的重要代表人物,提出了独特的精神分析治疗观,以提供抱持性的分析情境为核心,强调退行至依赖的治疗过程,重视精神分析师的反移情中的恨的情绪体验,珍视病人的主动不交流等,在很多方面颠覆了经典的精神分析治疗观。     

易感人格的工作记忆特征对药物成瘾的调节机制

药物成瘾是指持续使用成瘾药物, 出现耐受性和戒断症状并严重阻碍正常社会功能的精神疾病。工作记忆在调节药物成瘾行为中扮演了中心角色：在神经易感性和易感人格特质基础上, 低工作记忆容量导致危险决策和去抑制性, 进而影响寻求药物和复吸行为。目前的研究基于已经产生成瘾的个体, 无法区别神经易感性、人格特质以及工作记忆缺陷是药物成瘾的原因还是结果; 而且, 仅从认知角度研究药物成瘾的原因, 会忽视该行为受多个因素影响的事实。     

Assessment of Nicotine Dependence Among Substance Abusing Adolescent Smokers: A Comparison of the DSM-IV Criteria and the Modified Fagerström Tolerance Questionnaire

Nicotine dependence has been found to be a significant factor in adolescent smoking persistence. However, measures of this construct are primarily adult-derived, limiting their utility as bases for characterizing nicotine dependence and formulating youth intervention strategies. This issue is of particular importance among substance abusing youth who have substantially higher rates of cigarette smoking than do adolescents in the general population. The objectives of this preliminary study were to examine the construct validity of the DSM-IV nicotine dependence criteria and the modified Fagerström Tolerance Questionnaire (mFTQ) and to compare the DSM-IV diagnostic criteria for nicotine dependence with the mFTQ in a sample of 67 adolescent smokers in treatment for substance abuse. Results revealed that more participants were classified as nicotine dependent using DSM-IV criteria than by mFTQ scores. Little evidence was found for construct validity of these measures and convergence between the two measures was low. Findings also suggested that the present measures do not capture optimally broad dimensions of adolescent nicotine dependence.     

The Relationship between Local Identification,Urban Disorder Sensitivity,and Prejudice Toward Immigrants: The Role of Autochthony

Autochthony is the belief that a place belongs to those who were born there and that they are more entitled. Autochthony and local identification can foster sensitivity to any source of disorder that threatens local stability. The aims of this study were to determine whether: (a) local identification is associated with a higher level of sensitivity to urban disorder and a higher level of prejudice toward immigrants; (b) higher city identifiers use autochthony (entitlement for first comers) as a justification for both of these attitudes. A self‐report questionnaire was administered to 254 adult residents of Turin, Italy. Local identification was found related to autochthony and to urban disorder sensitivity, autochthony was positively associated with both urban disorder sensitivity and prejudice toward immigrants and it mediated the relationship between local identification and prejudice.     

Combining two separate series into a single ordering: Testing the local and global distinctiveness theories with absolute and relative judgments

This study examined the differential effects of an absolute versus a relative judgment task on the retrieval of the border-position items after the combining of two separate serial lists. Under the absolute judgment condition (Experiment 1), the border-position items showed a local distinctiveness effect (faster judgment on these items than on the neighboring items), consistent with the prediction of the local distinctiveness theory of order memory, but not under the relative judgment condition (Experiment 2). The absence of the local distinctiveness effect under the relative judgment condition was consistent with the prediction of the global distinctiveness theory that a midseries item cannot be remembered better than its neighbors. The causes of the differential effects of the two judgment tasks were discussed.     

干扰材料的熟悉性和认知方式对语篇阅读的影响

采用熟悉词和不熟悉词为干扰材料,考察了干扰材料的熟悉性对语篇阅读的影响.实验第一阶段要求不同认知方式被试朗读插入熟悉度不同干扰材料的短文,考查被试的阅读效率;第二阶段采用学习—自由回忆任务考查不同提示条件下在短文中使用过的干扰词和新词的学习效果.结果发现:(1)对场独立者而言,熟悉词的干扰作用明显大于不熟悉词,而对场依存者而言,熟悉词和不熟悉词的干扰作用无差异;(2)在提示条件下,被试对干扰词的回忆量大于对新词的回忆量.研究结果表明,在语篇阅读过程中,与场依存者相比,熟悉的干扰材料对场独立者的影响更大;熟悉词比不熟悉词产生更大干扰的原因可能是由于其激活了读者更多的经验,而非具有加工的优势.     

经颅直流电刺激技术在物质依赖治疗中的应用

物质依赖是一种慢性、复发性脑部疾病, 给个体及社会带来极大损害。研究发现, 经颅直流电刺激(transcranial direct current stimulation, tDCS)可以通过调节背外侧前额叶(dorsolateral prefrontal cortex, DLPFC)脑区的兴奋性降低物质依赖者的渴求, 并改善受损的认知功能。tDCS具有副作用小、操作简便、费用低廉等优点, 因此在物质依赖治疗领域应用前景广泛。未来应考虑确定最佳的刺激参数及刺激位置, 同时考虑物质依赖者的种类及个体差异, 与其他疗法结合使用, 并进一步深入探索tDCS治疗物质依赖的神经机制。     

Local context effects during emotional item directed forgetting in younger and older adults

This paper explored the differential sensitivity young and older adults exhibit to the local context of items entering memory. We examined trial-to-trial performance during an item directed forgetting task for positive, negative, and neutral (or baseline) words each cued as either to-be-remembered (TBR) or to-be-forgotten (TBF). This allowed us to focus on how variations in emotional valence (independent of arousal) and instruction (TBR vs. TBF) of the previous item (trial n-1) impacted memory for the current item (trial n) during encoding. Different from research showing impairing effects of emotional arousal, both age groups showed a memorial boost for stimuli when preceded by items high in positive or negative valence relative to those preceded by neutral items. This advantage was particularly prominent for neutral trial n items that followed emotional items suggesting that, regardless of age, neutral memories may be strengthened by a local context that is high in valence. A trending age difference also emerged with older adults showing greater sensitivity when encoding instructions changed between trial n-1 and n. Results are discussed in light of age-related theories of cognitive and emotional processing, highlighting the need to consider the dynamic, moment-to-moment fluctuations of these systems.     

自动化信任和依赖对航空安全的危害及其改进

自动化系统在现今航空业中得到了广泛应用,然而复杂的自动化系统的引入产生了新的失误模式,使航空人因安全问题变得更加突出。受多种因素影响,操作者在与自动化系统的交互过程中并不总能达到适度的信任校准水平。非适度自动化信任和依赖引发了严重的航空安全事故。值得欣慰的是,以人为中心的自动化显示设计和训练能够将非适度自动化信任和依赖调整到适度状态。
