工作记忆中转换加工的内源性准备 和外源性调节

考察工作记忆中转换加工的控制过程。采用“任务转换”范式,探究预知条件（实验一）和未预知条件（实验二）下的转换加工。结果发现：（1）任务重复与任务转换是两个不同的过程;无论是在预知条件还是未预知条件下都出现任务重复效应显著大于任务转换效应;（2）验证了转换加工包括内源性准备和外源性调节两个不同的加工过程, 内源性准备只是任务设置重建的一部分;（3）对先后呈现的两个任务（任务1—任务2 ：任务重复或任务转换）在预知重复、预知转换和未预知条件下,任务2对任务1的影响不同,存在前瞻性记忆效应。由此推断转换加工的心理过程是：在预知情况下,任务1呈现后即启动内源性准备,直到任务2呈现时,通过外源性调节最终完成任务转换;而在未预知情况下,只能依赖外源性调节来实现     

初中数学优差生注意转换中的线索和准备效应

选取34名初中数学优差生为被试,采用任务转换实验考察其注意转换中的线索效应和准备效应.结果表明:一般转换代价出现了线索效应和准备效应,特定转换代价仅出现了线索效应,优生比差生更善于利用线索和准备间距提高任务转换成绩.     

准备间隔对口吃者言语反应速度的影响

为了考察准备间隔对口吃者言语反应速度的影响,作者采用固定准备间隔下的预备反应时范式,设置了6种准备间隔,通过三个系列实验,检测口吃者的最佳言语准备间隔。结果发现,无论时间压力（项目间隔）怎样变化,口吃被试的问题在于,当准备间隔增加到800ms时,他们无法有效保持或提高反应速度;而且,这一现象只在言语命名任务上表现明显。作者认为,口吃者在言语运动准备过程中的异常,很可能是引起口吃现象的重要原因。     

多发性硬化诊疗指南评析

我国无统一的多发性硬化（MS）诊断标准,MS的诊断依据Poser标准和McDonald标准。McDonald标准是建立在Poser标准基础上,但更注意利用包括MRI在内的相关实验室检查来证明多发性硬化在时间和空间上的多发性,有利于MS的早期诊断及治疗。对于没有MRI仪器的地方或不能承担MRI检查费用者,可用Poser标准进行诊断,但要注意行视觉诱发电位检查及脑脊液寡克隆IgG区带测定。     

Academic achievement in first-year Portuguese college students: the role of academic preparation and learning strategies

This paper analyses the role of academic preparation and learning strategies in the prediction of first-year Portuguese college students' academic achievement, considering students' sex and academic field attended. A sample of 445 first-year college students (68.5% female) from the University of Minho (25.8% enrolled in economics, 35.3% in science/technology, and 38.9% in humanities degrees) participated in the study. Students answered a questionnaire on learning strategies in the classroom at the end of the first semester, which consisted of 44 items organized in five dimensions: comprehensive approach, surface approach, personal competency perceptions, intrinsic motivation, and organization of study activities. Academic achievement (grade point average at the end of first year) and academic preparation (students' higher education access mark) were obtained through the academic records of the university. Results showed that academic preparation was the strongest predictor of first-year academic achievement, and only marginal additional variance was explained by learning strategies as assessed by the self-reported questionnaire. There were sex and academic field differences, but these variables do not seem strong enough to affect the results, although the different percentages of variance captured by each model and the different weights associated to higher education access mark, stimulate the use of these and/or other personal and contextual variables when analysing the phenomenon.     

Coping,mastery, stress appraisals,mental preparation,and unit cohesion predicting distress and performance: a longitudinal study of soldiers undertaking evacuation tasks

Abstract

The study aimed to assess the associations of psychological and military variables with distress and performance evaluation among 168 Israeli soldiers who took part in evacuating fellow Israeli civilians in the summer of 2005 during the disengagement from Gaza. Coping, mastery, stress appraisals, mental preparation, unit cohesion, and psychological distress were assessed at T1, one to two weeks before the disengagement. A sub-sample of 68 of the 168 soldiers completed the distress measure again at T2, eight to nine weeks after T1, together with performance evaluation of the disengagement task. The main findings indicated positive associations of T1 distress with high T1 emotion-focused coping, and negative associations with education and T1 mastery. Emotion-focused coping at T1 predicted low performance evaluation at T2, while mental preparation at T1 predicted high performance evaluation at T2. Stress appraisals at T1 were found to be an important mediator of the associations of T1 coping, mastery, unit cohesion, and mental preparation with T1 distress. Similar mediator results were found for T2 performance evaluation.     

Domestic Violence

Summary

In this paper, the authors outline their experience in incorporating a curriculum on domestic violence into an urban family practice residency program. Based on the concept that in order to successfully develop such a curriculum, it is necessary to address the “culture of the organization,” joint educational strategies that in-elude resident education as well as faculty development were considered. A research question was designed to inquire as to the difference in the level of knowledge about domestic violence in family practice faculty as compared to residents prior to the introduction of educational strategies. The authors describe curriculum goals and objectives and outline specific teaching methods as well as the evaluation instrument utilized in the study to measure actual difference in knowledge between faculty and residents about domestic violence with a focus specifically on spousal abuse. Their conclusions point to the need for an educational strategy that includes emphasis on the faculty-resident interface which utilizes both traditional and non-traditional integrated formats in order to successfully train residents in the identification and treatment of domestic violence.     

Decomposition of warning effects in Parkinson's disease

ABSTRACT

Neutral warning signals speed voluntary reactions by reducing temporal uncertainty and by triggering a brief burst of arousal. We attempted to isolate the phasic arousal mechanism in people with Parkinson's disease (PD) using a clock display to minimize temporal uncertainty. In this condition, the speeding of responses in a color-discrimination task by an accessory stimulus was the fully equivalent to the effect in age-matched control subjects. This indicates preserved phasic arousal in PD. Temporal preparation based on warning cues also appeared to be normal. By contrast, in a condition with high temporal uncertainty, the accessory stimulus (an air puff to the foot) impaired accuracy for the patients but not the neurologically normal subjects. The data are consistent with the view that PD disrupts internal but not external control of alertness.     

Counselor Preparation and the Association for Spiritual,Ethical, and Religious Values in Counseling Competencies: An Exploratory Study

A national study of American Counseling Association members (N = 230) examined perceptions of the importance of the 14 Association for Spiritual, Ethical, and Religious Values in Counseling (ASERVIC) Spiritual Competencies and perceived ability to practice those competencies. Learning pathways to achieve knowledge of the ASERVIC Competencies were explored. Participants viewed the competencies as important but felt less able to consistently practice them. Prior exposure to the content of the competencies through spiritual topics covered in graduate school was positively correlated to perceived ability to practice the competencies. Recommendations were made for strengthening teaching of spirituality in counselor education.     

Evaluating the use of preparation guides in interteaching versus a quiz alternative

Interteaching is a behavioral teaching method that has demonstrated efficacy in higher education. Of particular interest is the use of a preparation guide (a guided reading assignment), which is designed to promote engagement in the other areas of the interteaching process. The present study compared the use of a preparation guide completed before the start of class with that of a quiz administered at the start of the class. The quiz was hypothesized to serve as a functional alternative to the preparation guide. A total of 38 undergraduate students enrolled in an Introduction to Psychology course participated in this study. The primary dependent measure was student performance on tests following each condition. The analysis revealed no statistically significant difference between the conditions, F(1, 302) = 0.103, p = .748, though qualitative feedback revealed student preference for preparation guides. Future research is necessary to examine the effects of quizzing while addressing the limitations of this study.
