东西方面孔异族效应机理的电生理学证据

采取事件相关电位方法研究东西方面孔记忆编码的差异（DM效应）,从而阐明异族效应的神经机制。14名被试学习和再认东西方面孔照片的实验结果表明,无论记住与否,西方面孔产生的早期成分（潜伏期70~220ms）在头皮额部有一个比东方面孔更为正向的变化,表明在此阶段更多的资源分配于异族面孔,支持异族效应产生的特征选择假说。无论东方面孔还是西方面孔,记住与未记住相比较,则在额部和顶部产生潜伏期在晚期正成分（LPC）范围的正走向变化,但西方面孔在240~320ms潜伏期范围内,DM效应较小。另外,东方面孔在枕部诱发出一个明显的负波N260,而西方面孔产生的N260很小甚至没有,反映了大脑对不同种族面孔的编码机制有所不同,因而可能被称为“种族特异波”     

Modeling the Ecological Validity of Neurocognitive Assessment in Adults with Acquired Brain Injury

Neuropsychologists are increasingly asked to make judgments regarding treatment options and rehabilitation strategies in addition to evaluating the degree and scope of neuropsychological impairment following acquired brain injuries. The capacity to make informed clinical decisions relies upon research investigating the relationships between neuropsychological and psychosocial status (i.e., ecological validity). Unfortunately, much of this research employs exploratory analyses, an approach that can lead to theoretical ambiguity and ad-hoc interpretations. The current availability and accessibility of analytical tools, like structural equation modeling (SEM), however, permits the testing of specific hypotheses regarding ecological validity and promotes a-priori theory development. In the current study, a theory-driven model of the ecological validity of a neurocognitive assessment was tested against data obtained from individuals with acquired brain injury using SEM. The results provide confirmatory evidence for the ecological validity of neurocognitive constructs and empirical support for a theory-driven analytical approach to ecological validity research.     

Preliminary evaluation of a parent training program to prevent gun play

Recent research has shown that behavioral skills training with in situ training is an effective strategy to teach children the safety skills needed if they ever encounter an unattended firearm. The current study evaluated the use of parents as trainers to increase the efficiency of training. The success of parent training on their children's safety skills was evaluated in a multiple baseline across participants design. The results showed that the training was effective for 3 of the 4 children.     

Ambivalent sexism,attitudes towards menstruation and menstrual cycle‐related symptoms

The objective of the present study was to investigate the relationship between ambivalent sexism and beliefs and attitudes towards menstruation, and, in turn, to study the influence of these variables on menstrual cycle‐related symptoms. One hundred and six Mexican women completed the Ambivalent Sexism Inventory, the Beliefs about and Attitudes toward Menstruation Questionnaire and the Menstrual Distress Questionnaire. The higher scores on benevolent sexism were associated with the most positive attitudes towards menstruation and also with the belief that a menstruating woman should or should not do some activities and that menstruation keeps women from their daily activities. The higher scores on hostile sexism were associated with rejection of menstruation as well as with feelings of embarrassment about it. Beliefs about and attitudes towards menstruation predicted menstrual cycle‐related symptoms related to negative affect, impaired concentration and behavioural changes, but did not predict somatic symptoms. These results will be useful to health professionals and advocates who want to change the negative expectations and stereotypes of premenstrual and menstrual women and reduce the sexism and negative attitudes towards women that are evident in Mexican culture.     

Strategic retrieval processing and the impact of knowing when a memory was first created

Retrieval orientation refers to a process where participants strategically alter how a memory cue is processed in response to different task demands. In the present study we explored whether retrieval orientation is influenced by knowing when an old stimulus was first encoded. Participants completed separate remember/know test blocks for old items from a recent delay (40 min) and old items from a remote delay (48 h). Manipulations at encoding ensured that performance levels were matched between these two blocks, thus avoiding confounds with differences in retrieval effort. Importantly, a third test block comprised old items from both delays randomly intermixed. As the nature of the old items varies unpredictably in the mixed block, it should not be possibly to adopt a specific retrieval orientation and the mixed block therefore acts as a control condition. Participants saw the words “mixed,” “recent” or “remote” prior to each test block. Comparing ERPs from the recent and remote blocks permitted an investigation of whether participants alter their retrieval orientation in response to the specific length of the retention interval. Comparing ERPs from the pure (recent and remote) test blocks to ERPs from the mixed block permitted an investigation of whether delay information per se led to differences in retrieval strategy. Analysis of the ERP data found no differences between the recent and remote blocks. However, ERPs from these pure blocks were significantly less positive than ERPs from the mixed block from 200 ms towards the end of the epoch. The findings suggest that the delay information was useful in a general sense and encouraged retrieval strategies distinct from those engaged in the mixed block. We speculate that such strategies might relate to whether or not the retrieval search is specific and constrained and/or whether processes that serve to reinstate the original encoding context are engaged.     

Naturalistic Recovery From Nonsuicidal Self‐Injury: A Phenomenological Inquiry

The authors conducted a phenomenological inquiry of 12 individuals who recovered from nonsuicidal self‐injury without psychotherapeutic or medical intervention. Results indicated that participants’ naturalistic recovery emanated from their recognition of serious physical damage, corrective interpersonal influences, and movement from unhealthy to healthy surroundings. Implications of these findings for clinical practice and future research are discussed.     

The Development and Experience of Combat‐Related PTSD: A Demand for Neurofeedback as an Effective Form of Treatment

Veterans experience a considerable course of posttraumatic stress disorder (PTSD), and because of several psychosocial issues, traditional interventions and traditional intervention settings are ineffective for this population. A new cutting‐edge approach, known as neurofeedback, trains clients to control and manipulate their central nervous system and ameliorate physiological symptoms of stress disorders. The authors delineate how neurofeedback can be an effective and innovative intervention for PTSD experienced by the military population.     

An examination of post-traumatic growth in Canadian and American ParaSport athletes with acquired spinal cord injury

ObjectivesThe study was guided by two research questions: (1) Does participation in ParaSport following acquired spinal cord injury (SCI) influence people's perceptions of post traumatic growth (PTG)? (2) What specific dimensions of PTG, if any, do ParaSport athletes report experiencing?DesignA phenomenological approach was adopted to understand ParaSport athletes' perceptions and experiences of PTG and sport participation following acquired SCI.MethodTwelve participants with acquired SCI who integrated, reintegrated, or attempted to integrate into sport completed a survey and participated in a semi-structured interview to assess their perceptions of acquired SCI, involvement in ParaSport, and PTG.ResultsFive general dimensions of growth emerged from the data including: (a) injury relevant processing; (b) appreciation for life; (c) reactive behavior as a result of attempted integration into ParaSport; (d) relating to others and (e) health and well-being. Participants reported increased physical functioning and independence related to their involvement in sport. Emotional and psychological gains were also associated with ParaSport including re-establishment of self-identity, improved clarity and perception of life, changed priorities, greater confidence, and enhanced social relationships.ConclusionsParticipation in ParaSport following acquired SCI may provide physical, emotional, and psychological health benefits, which should be considered in the development and implementation of sport related interventions to encourage PTG. Clinicians and rehabilitation specialists may use information from the present study to help individuals improve their identity, build relationships, and develop an appreciation for life after incurring a SCI.     

The Causes,Course, and Consequences of Anger Problems in Veterans Returning to Civilian Life

While anger is a common problem for veterans returning from wars in Afghanistan and Iraq, veterans' understanding of the causes, course, and consequences of anger has not been explored. We conducted this qualitative study to learn veterans' perspectives about their anger problems. We identify and describe three distinct patterns of anger problems that emerged as a consequence of (a) loss of structure during reintegration to civilian life, (b) moral injury sustained through a wartime experience, and (c) posttraumatic stress disorder (PTSD). While anger problems tended to be short lived for those experiencing loss of structure, problems persisted for years for those with moral injury or PTSD. Anger following all three patterns negatively impacted veterans' experiences with reintegration. We discuss the implications of these findings.     

Predictors of re‐employment: A question of attitude,behavior, or gender?

This longitudinal study examined the predictive value of attitudes, personal‐related variables, job search behaviour, and demographic variables on re‐employment among 142 assembly workers who had been made redundant. Participants completed a questionnaire within a week after leaving their jobs, and another 15 months later. Results of hierarchical logistic regression revealed that gender (being male), was the strongest predictor of re‐employment. Willingness to relocate and desire to change occupation also increased the odds of re‐employment 15 months after dismissal. On the other hand ‐ having children at home and anonymous‐passive job‐search behaviour, which is more prevalent among women, decreased the odds for re‐employment. The study is contributing to research by revealing gender differences in job search behaviour and the importance of focusing qualitative differences instead of merely quantitative measures in job‐search behaviour. And even more important, despite attitude and job‐search behaviour, there is still differences that seems to be related to gender and family responsibility.
