两种自我保护机制：记忆忽视和自我免疫

当自我概念的稳定性受到威胁时,人们有时会采取自我保护手段来加以应对。在诸多自我保护方式中,记忆忽视加工是指个体在接触具威胁性的信息时进行选择性记忆,自然地忽视此类信息而不让其进入精加工,以消除该信息对自我概念的伤害;自我免疫加工是指个体通过对具威胁性信息的适宜操作界定来强调自己的优势能力,并重新评估自己的弱点,从而策略性地实现自我概念的稳定。文章从两种加工的认知机制角度来介绍和评述该领域的研究概况、研究方法与研究展望,借以引起对自我保护机制研究新进展的关注     

Child victims: Searching for opportunities to break the cycle of violence

In 1986 I began research to address the relationship between early child abuse and neglect and later deliquent and violent criminal behavior using a prospective cohort design. The relationship is not inevitable, suggesting an opportunity for long-range violence prevention through appropriate early intervention. Here, I briefly describe how childhood victimization and violent criminal behavior are related and illustrate a number of promising strategies and opportunities to intervene. Finally, I offer five principles to guide interventions: (1) the earlier the intervention, the better; (2) don't neglect neglected children; (3) one size does not fit all; (4) surveillance—a double-edged sword; and (5) accessibility to resources. Rather than focusing on responses to child abuse or neglect in court proceedings that “treat” offenders, primary prevention efforts should target childhood victims to reduce their risk of becoming offenders in the future.     

The effects of focal and global attentional systems on spatial biases

The background page on which a stimulus is presented can influence the allocation of attention to that stimulus. The purpose of this study was to learn if there are hemispheric asymmetries in how background distraction affects attentional processing. Asymmetries were investigated by having right eye dominant subjects perform line bisections and manipulating the side of background distraction (right versus left), the eye of regard (right versus left), and the type of attention allocated (focal versus global). Overall subjects bisected lines to the left of center (pseudoneglect) and when viewing with the right eye (versus left) deviated more to the left. Subjects had more background distraction when viewing symbol than solid lines. Although overall, bias did not differ with the side of background distraction or the line being on one side or the other, when subjects viewed symbol, but not solid lines, this leftward bias was increased when the line was displaced to the right, thereby increasing the size of the left sided background. These findings suggest that when engaging the left hemisphere by using focused attention and placing the line on the right side, there is more distraction than when the right hemisphere is engaged.     

Availability to peer group treatment in residential care as a function of relational ethics

Forty-five adolescent boys from abusive and depriving homes were not doing well in positive peer culture residential care. Despite their backgrounds, given a modified form of the Relational Ethics Scale, they indicated that their relational life with their families of origin was trustworthy, fair, and worthy of continued devotion. In contrast, on the Firo-B these same boys demonstrated distrust of others outside of their families and an unwillingness to get involved. These results support the inference from contextual family theory that peer group interventions cannot bypass identification and resolution of the injustices that took place in the family of origin.This project was fully supported by Teen Ranch, Inc., Marlette, MI 48453.     

贝叶斯推理研究综述

Kahneman 和Tversky在70年代初期发现人们在概率推理中并不遵循数学上的贝叶斯定理,常常由于忽略问题中的基础概率而对稀少事件的条件概率作出夸大的反应。此后心理学家采用文本范式和经验范式对此问题进行了大量的研究,并涌现了一些不同的理论观点,主要有启发法策略论(代表性启发法和可得性启发法)、自然抽样空间假说、频率效应论和抽样加工理论。     

Spatial analysis after perinatal stroke: patterns of neglect and exploration in extra-personal space

This study was conducted to determine whether school-aged children who had experienced a perinatal stroke demonstrate evidence of persistent spatial neglect, and if such neglect was specific to the visual domain or was more generalized. Two studies were carried out. In the first, 38 children with either left hemisphere (LH) or right hemisphere (RH) damage and 50 age-matched controls were given visual cancellation tasks varying in two factors: target stimuli and stimulus array. In the second study, tactile neglect was evaluated in 41 children with LH or RH damage and 72 age-matched controls using a blindfolded manual exploration task. On the visual cancellation task, LH subjects omitted more target stimuli on the right, but also on the left, compared with controls. Children with RH lesions also produced a larger number of omissions on both the left and right sides than controls, but with poorer performance on the left. On the manual exploration task, LH children required significantly longer times to locate the target on both sides of the board than did controls. RH children had significantly prolonged search times on the left side, but not on the right, compared with controls. In both tasks, LH subjects employed unsystematic search strategies more often than both control and RH children. The search strategy of RH children also tended to be erratic when compared to controls, but only in the random arrays of the visual cancellation tasks; structure of the target stimuli improved their organization. These results demonstrate that children with early LH brain damage display bilateral difficulties in visual and tactile modalities; a pattern that is in contrast to that seen in adults with LH damage. This may result from disorganized search strategies or other subtle spatial or attentional deficits. Results of performance of RH children suggests the presence of contralateral neglect in both the visual and tactile modalities; a finding that is similar to the neglect in adult stroke patients with RH lesions. The fact that deficits in spatial attention and organizational strategies are present after very early focal damage to either the LH or the RH broadens our understanding of the differences in functional lateralization between the immature and mature brain. These results also add to evidence for limitations to plasticity in the developing brain. Our findings may have therapeutic and rehabilitative implications for the management of children with early focal brain lesions.     

儿童期情感忽视对大学生抑郁的影响:控制感与情绪调节自我效能感的链式中介作用

为探讨儿童期情感忽视与大学生抑郁的关系,以及控制感和情绪调节自我效能感在其中的中介作用,采用儿童期创伤问卷、控制感量表、情绪调节自我效能感量表和贝克抑郁量表(第2版),对重庆市两所高校共837名大学生进行调查。结果显示:(1)儿童期情感忽视显著正向预测大学生抑郁;(2)控制感、情绪调节自我效能感在儿童期情感忽视与抑郁之间起独立中介作用;(3)控制感与情绪调节自我效能感在儿童期情感忽视与抑郁之间起链式中介作用,且情绪调节自我效能感各维度的效应皆成立。本研究考察了儿童期情感忽视对抑郁的影响及其作用机制,为家庭教养方式的改善及大学生抑郁问题的预防与干预提供了实践启示。     

Can probability neglect bias promote social distancing during the COVID-19 pandemic?

The effectiveness of a stay-at-home order depends on the speed of behavioral changes that are triggered by risk perception. Probability neglect bias, one of the cognitive biases, may lead people to engage in social distancing. However, there is no empirical evidence of the relationship between probability neglect bias and social distancing. This study aims to examine the relationship between individual differences in susceptibility to probability neglect bias and the level of social distancing practice during the early stages of the COVID-19 outbreak in Japan. The level of engagement in social distancing was defined as the narrowing of life-space mobility. We conducted a web-based questionnaire survey among 1000 adults living in central Tokyo, Japan, at the beginning of the pandemic outbreak. Our results show that people had a strong fear of infection in the early pandemic stages. Approximately 60% of our subjects were influenced by probability neglect bias. People susceptible to probability neglect bias engaged in social distancing more intensely than those who were not susceptible after the state of emergency was lifted.     

From “It's Not Me” to “It Was Me,After All”: A Case Presentation of a Patient Diagnosed with Dissociative Identity Disorder

In cases of extreme childhood trauma associated with abuse and neglect, one's sense of self is seriously compromised. Attachment patterns, symptoms, defensive operations, and character formation will differ depending upon the level of interference and impingement. When repeated trauma occurs in early childhood, the dissociative response may become the first line of defense for the person to rely upon. In its most severe form, patients are diagnosed with Dissociative Identity Disorder (DID). This paper addresses the case of a woman diagnosed with DID. It describes the restoration of a cohesive sense of self from the eight parts of a dissociated and fragmented self in the course of therapy. The clinical case material presented is that of the child part of her, known as Lucy. Her treatment resulted in the integration of the “it's not me!” self to the patient's knowledge that “it was me, after all.”
