质性比较专家与新手的物理学知识结构

通过质性比较方法,本实验刻画了专家与新手在物理学欧姆定律上的知识差异,并发现,与新手相比,专家的知识结构有如下特点:(1)精致化,即拥有更多公式且生成了新公式,表示他们在知识之间形成了更多联系;(2)限制化,即添加更多恒定条件于知识中,从而产生更为明确的行动。此外,本实验在方法学上为细致描述和解释专长的实质提供了可能。     

大中小学生内隐序列学习的发展性研究

采用序列学习的研究范式,对大中小学生的序列反应时和序列生成成绩进行测量,结果表明:(1)大中小学生均能在序列学习中获得序列规则。(2)采用比例测量方法,大中小学生的序列反应时无显著差异。(3)大中小学生的序列生成成绩是不同的,包含成绩随着年级升高而上升,排除成绩则不随年级变化;小学生包含和排除成绩无显著差异,而中学生和大学生的差异逐渐加大。说明序列学习的意识成分随年级的升高而增加。     

Predicting post‐traumatic growth and post‐traumatic stress in firefighters

Emergency service workers (e.g., firefighters, police, and paramedics) are exposed to elevated levels of potentially traumatising events through the course of their work. Such exposure can have lasting negative consequences (e.g., post‐traumatic stress disorder (PTSD)) and/or positive outcomes (e.g., post‐traumatic growth (PTG)). Research had implicated trauma, occupational and personal variables that account for variance in post‐trauma outcomes yet at this stage no research has investigated these factors and their relative influence on both PTSD and PTG in a single study. Based in Calhoun and Tedeschi's model of PTG and previous research, in this study regression models of PTG and PTSD symptoms among 218 firefighters were tested. Results indicated organisational factors predicted symptoms of PTSD, while there was partial support for the hypothesis that coping and social support would be predictors of PTG. Experiencing multiple sources of trauma, higher levels of organisational and operational stress, and utilising cognitive reappraisal coping were all significant predictors of PTSD symptoms. Increases in PTG were predicted by experiencing trauma from multiple sources and the use of self‐care coping. Results highlight the importance of organisational factors in the development of PTSD symptoms, and of individual factors for promoting PTG.     

Can CBT Be Effective for Aboriginal Australians? Perspectives of Aboriginal Practitioners Trained in CBT

The objective of the study was to investigate whether high and low intensity versions of cognitive behaviour therapy (CBT) might be an effective therapeutic approach for enhancing the mental health of Aboriginal Australians. Five university‐educated Aboriginal counsellors received in‐depth training in CBT. Over the following year, they used CBT strategies with their clients, and met 10 times as a participatory action research group. The group addressed three key questions: (a) Does CBT appear to be useful for Aboriginal Australians? (b) If so, what elements of CBT are perceived to be effective? (c) What adaptations might be made to CBT to enhance its effectiveness with Aboriginal Australians? The resulting qualitative data were transcribed and analysed. Counsellors perceived CBT to be very useful for their Aboriginal clients and for themselves. They reported that it enhanced their clients' well‐being, their own clinical skills, and their own well‐being, and it reduced burnout. The qualities of CBT that were perceived to be effective were its adaptability, pragmatic here‐and‐now approach, capacity for low‐intensity interventions, safe containing structure, promotion of self‐agency, and valuable techniques. It was suggested that the prime requirement for adaptations to CBT were that they would need to fit different social and cultural contexts.     

Velocity discrimination: reliability and construct validity in older adults

The aim of this study was to determine whether a test of velocity discrimination is a reliable and valid measure of proprioception in healthy older adults. Results revealed excellent test-retest reliability over a 2-week period. Velocity discrimination also indicated good construct validity with modest correlations with center of pressure sway outcomes in eyes open and closed conditions as well as stair climbing time. Good construct validity was identified by velocity discrimination sensitivity to age with a higher mean value for the older participants than for the younger participants. These findings suggest velocity discrimination is a valid and reliable measure of velocity sense, which may be included with measures of position and movement sense to enhance the proprioceptive testing repertoire among researchers. Implications of these results are discussed in terms of evaluation of proprioceptive training programs aimed to enhance postural control.     

应征公民心理选拔的人格评估

Assessing Violence Risk: A Review and Clinical Recommendations

Guidance to identify and manage clients with a perceived high risk for future violence is of great importance for mental health professionals. In the past decade, several structured instruments have been developed to assess risk of future violence. Awareness of the limits and abilities of such instruments is required. This article reviews the most well‐known risk assessment tools and provides recommendations for how to approach the area of violence risk assessment.     

Spirituality and Counselor Competence: A National Survey of American Counseling Association Members

A random sample of 505 American Counseling Association (ACA) members completed a questionnaire that evaluated respondents' ratings of the importance of 9 competencies developed at the Summit on Spirituality (G. Miller, 1999; “Summit Results,” 1995) meetings to effectively address spiritual and religious issues in counseling practice. Results suggest that, in general, ACA members strongly support the importance of the competencies for effective counseling practice.     

Enhancing children's event recall after long delays

The effects of context reinstatement as means of enhancing 5‐ and 6‐year‐old children's event memory in repeated interviews after a 6‐month delay were examined. Children were interviewed immediately after the event (baseline interview) and twice at a 6‐month delay, with 24 hours between interviews. The first 6‐month interview was conducted in a perfect‐context reinstatement (n = 15), imperfect‐context reinstatement (n = 16), or no‐context reinstatement (n = 15) condition. The second 6‐month interview was conducted 24 hours later with no‐context reinstatement for all children. Context reinstatement attenuated the effects of delay on recall. The accuracy of the details reported was greater in the perfect‐context compared to the imperfect‐context and no‐context conditions. Details repeated between the immediate‐baseline interview and in the first 6‐month interview were more accurate than details repeated between the first and second 6‐month interview. There was no increase in recall (hypermnesia) across the first and second 6‐month interviews in any condition. Practical implications of these findings are discussed.
