Some women at increased familial risk of breast cancer experience elevated levels of cancer-specific worry, which can possibly act as a barrier to screening, and may be a significant factor in decisions regarding risk-reducing surgery. The aim of this study was to comprehensively examine predictors of cancer-specific worry in high risk women and to test a model which proposes that perceived breast cancer risk mediates the impact of other factors on worry. 1,437 unaffected women from high risk breast cancer families completed questionnaires and interviews. Path analysis was used to test the model of potential predictors of cancer worry, including familial, personal and psychological variables, mediated via perceived cancer risk. Levels of cancer-specific worry were generally low despite an average perceived risk of 50.3%. The goodness-of-fit of the proposed model was poor, explaining only 9% of the variance for perceived risk and 10% of the variance for cancer specific worry. An alternative model of a direct relationship between all of the predictor variables and cancer worry, explained 24% of the variation in cancer worry. General anxiety, perceived risk, the stressful impact of recent cancer related events, a relative risk greater than 10, being closer in age to the youngest breast cancer diagnosis in family, and knowledge of personal mutation status, all independently contributed to cancer worry. Addressing general affective responses, experiences of recent cancer related events, in addition to education about personal risk, should be considered in counselling women with elevated cancer worry. Risk perception appears to act independently of other factors in its formulation and impact on cancer worry. Further research on the way in which women come to perceive their risk is indicated.

Although Alain Badiou dedicates a number of texts to the philosophy of Benedict de Spinoza throughout his work—after all, the author of a systematic philosophy of being more geometrico must be a point of reference for the philosopher who claims that “mathematics = ontology”—the reading offered in Meditation Ten of his key work Being and Event presents the most significant moment of this engagement. Here, Badiou proposes a reading of Spinoza’s ontology that foregrounds a concept that is as central to, and celebrated in, his philosophy as it is strictly excluded by Spinoza: the void. In nuce, Badiou contends that for all of Spinoza’s efforts to offer an ontology of total plenitude, the void returns in his philosophy under the (at first sight) unlikely name of infinite mode. The presence of this errant name in Spinoza’s philosophy bears witness to the failure of his most profound intellectual endeavour. However striking Badiou’s reading of Spinoza, this paper argues that it fails to adequately grasp Spinoza’s metaphysics, particularly with respect to the central concept of modal essence, a concept which does not appear at all in the Badiouian text. By introducing a consideration of this concept, it becomes able to resolve the status of infinite modes, and to account for the move across the notorious finite–infinite divide. Thus the argument turns to the reading of Spinoza offered by Gilles Deleuze for a more thorough-going and nuanced approach, much superior to Badiou’s procrustean critique.

采用探测词和事件分割范式探讨了空间转换与事件转换分离的情况下, 空间转换在记叙文情境模型建构中的作用。实验1a重复前人研究, 探讨空间转换对阅读时间和情境模型更新的影响, 并验证在空间转换对情境模型的影响的研究中, 采用多指标探测范式的合理性。实验1b探讨在空间转换与事件转换相分离的条件下, 空间转换对情境模型更新的影响; 实验2a探讨空间转换对事件分割的影响, 并验证在空间转换对情境模型的影响的研究中, 采用事件分割范式的合理性; 实验2b探讨空间转换与事件转换相分离的条件下, 空间转换对事件分割的影响, 从而验证空间转换对情境模型更新的影响。结果表明, 当空间转换与事件转换相分离时, 不引起情境模型的更新, 事件单元是建构记叙文心理表征的核心单元, 空间转换只有在标识事件转换的情况下, 才能引发读者更新情境模型。  相似文献

研究考查了大学生对一般生活事件和意外事故的乐观与悲观偏差,并检验不同测量方法是否会产生不同结果。通过对273名大学生进行问卷研究,结果发现:(1)在直接和间接测量时,被试对一般消极事件、意外事故存在乐观偏差,对幸免于意外事故存在悲观偏差;但对一般积极事件,被试在直接测量时出现乐观偏差,在间接测量时为悲观偏差。(2)在两种方法中,被试对意外事故的乐观偏差皆高于一般消极事件,但一般积极事件与幸免于意外事故的结果在直接测量时有显著差异,而在间接测量中差异不显著。(3)在直接测量时,消极事件的发生频率越低乐观偏差越严重,积极事件的发生频率越低则悲观偏差越严重;在间接测量中事件频率与偏差结果相关不显著。  相似文献

认知加工中时间与非时间信息的相互关系   总被引:2,自引:0,他引:2  
黄希庭  郭秀艳  聂晶 《心理科学》2003,26(5):770-774
在认知心理学领域,关于时间信息和非时间信息在认知加工中关系的争论有:相互独立、相互竞争、相互促进三大观点。本文对支持这三种观点的实验分别进行了分析、整理,并在此基础上概括出特定条件下时间信息与非时间信息的相互关系:事件结构一致条件下,两类信息在认知加工中表现为相互促进;如果事件结构不一致,而心理负荷(即两类信息所需注意资源之和)超过了注意总资源,两类信息表现为相互竞争;若心理负荷没有超过注意总资源,两类信息则表现为相互独立。  相似文献

Inspired by the revised Behavioural Inhibition System (BIS) theory the present study probed the association between individual differences in Trait BIS and electroencephalogram indicators of conflict processing/inhibition. Sixty‐nine male participants either high or low in Trait BIS completed a Go/No‐Go task while the electroencephalogram was recorded. As expected, Trait BIS was associated with the No‐Go‐anteriorisation of the P300 event‐related potential (i.e. an index of response inhibition presumably generated in the dorsal anterior cingulate—an area implicated in conflict processing) and with No‐ Go‐related changes towards left frontal alpha activity (i.e. presumably more activity in right prefrontal cortex—an area implicated in response inhibition). These findings support the role of conflict processing attributed to BIS functioning in the revised theory. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

The ability of 2-month-old infants to discriminate changes in a 5-object crib mobile following a retention interval of 24 hr was assessed using the mobile conjugate reinforcement paradigm. Infants were trained in 3 daily 15-min sessions to produce mobile movement by footkicking. Twenty-four hr later, independent groups received generalization tests with mobiles containing 1–5 novel objects substituted into their original training mobile. A control group was tested with the original training mobile. These findings were compared with findings of 2 previous studies involving identical procedures with 3-month-olds, reanalyzed for measures of individual performance over successive test minutes. Although, in absolute terms, 2-month-olds had a flat generalization gradient relative to 3-month-olds, when each infant's kick rate during the generalization test was expressed relative to that infant's kick rate before, and at the end of, training, it was found that the generalization gradients of 2- and 3-month-olds were indistinguishable. The relative response measures indicated a surprising degree of specificity by both age groups: Test mobiles containing more than 1 novel object did not cue retrieval, but test mobiles containing no more than 1 new object yielded perfect retention and complete generalization. These data indicate that infants as young as 2 months are capable of encoding and maintaining a representation of the specific details of their training context for at least 24 hr and, after that delay, can perform fine discriminations based on the discrepancy between their test context and that representation.  相似文献

We investigate methods developed in multiple criteria decision‐making that use ordinal information to estimate numerical values. Such methods can be used to estimate attribute weights, attribute values, or event probabilities given ranks or partial ranks. We first review related studies and then develop a generalized rank‐sum (GRS) approach in which we provide a derivation of the rank‐sum approach that had been previously proposed. The GRS approach allows for incorporating the concept of degree of importance (or, difference in likelihood with respect to probabilities and difference in value for attribute values), information that most other rank‐based formulas do not utilize. We then present simulation results comparing the GRS method with other rank‐based formulas such as the rank order centroid method and comparing the GRS methods using as many as three levels of importance (i.e., GRS‐3) with Simos' procedure (which can also incorporate degree of importance). To our surprise, our results show that the incorporation of additional information (i.e., the degree of the importance), both GRS‐3 and Simos' procedure, did not result in better performance than rank order centroid or GRS. Further research is needed to investigate the modelling of such extra information. We also explore the scenario when a decision‐maker has indifference judgments and cannot provide a complete rank order. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

人格特征对胃癌发病的影响   总被引:12,自引:0,他引:12  
使用C型行为特征问卷、生活事件量表和RBC-C_(3b)R、RBC-IC、RCIA、CIC和C_3等免疫功能的检测,调查和检测了30名胃癌患者和50名健康者。结果表明:(1)胃癌组比健康组在焦虑、抑郁、愤怒内泄、控制等方面得分高,在愤怒外泄、乐观、社会支持等方面得分低;(2)胃癌患者在确诊前8年内有76%的患者遇到生活事件,在确诊前3年内有62%的患者遇到生活事件;(3)胃癌组RBC-C_(3b)R含量低,RCIA含量和CIC水平上升。初步结论:胃癌的发生与患者的一些行为特点有关,主要是抑郁并不表达愤怒;生活事件可作为应激源诱发胃癌;其机制可能与免疫功能有关。  相似文献
