大学生优秀辩手与非辩手的非形式推理能力比较

为考察大学生优秀辩手与非辩手非形式推理能力的差异,运用"提示访谈法"对大学生中的优秀辩手与非辩手的普通大学生进行了比较研究。结果表明:大多数优秀辩手达到间接反驳推理水平,而多数非辩手处在直接反驳推理水平。优秀辩手不论在功能性和条件性理由的数量上,还是在理由领域广度上都显著优于普通大学生。在反驳式推理过程中,优秀辩手的间接反驳次数显著多于非辩手。研究表明大学生优秀辩手的非形式推理能力显著优于非辩手。     

Interaction of Combat Exposure and Unit Cohesion in Predicting Suicide‐Related Ideation Among Post‐Deployment Soldiers

Suicide is one of the leading causes of death among U.S. Army soldiers. Suicide‐related ideation, which is associated with suicide attempts and suicide, can cause considerable distress. In a sample of 1,663 recently redeployed soldiers, we used factor analysis and structural equation modeling to test the associations between combat exposure, unit cohesion, and their interaction in predicting suicide‐related ideation. We found that combat exposure was a significant risk factor for suicide‐related ideation, while unit cohesion was a significant protective factor. The significant interaction between the two factors indicated that soldiers who experienced greater combat exposure but also had higher levels of unit cohesion had relatively lower levels of suicide‐related ideation. In addition, those who had higher levels of combat exposure and lower unit cohesion were most at risk for suicide‐related ideation. Our findings indicate the importance of unit cohesion in protecting soldiers from suicide‐related ideation and suggest a higher risk group of soldiers who should be targeted for interventions.     

Mood,Anxiety, and Substance‐Use Disorders and Suicide Risk in a Military Population Cohort

There are meager prospective data from nonclinical samples on the link between anxiety disorders and suicide or the extent to which the association varies over time. We examined these issues in a cohort of 309,861 U.S. Air Force service members, with 227 suicides over follow‐up. Mental disorder diagnoses including anxiety, mood, and substance‐use disorders (SUD) were based on treatment encounters. Risk for suicide associated with anxiety disorders were lower compared with mood disorders and similar to SUD. Moreover, the associations between mood and anxiety disorders with suicide were greatest within a year of treatment presentation.     

The role of blood pressure, cortisol, and prolactine among soldiers injured in the 1991–1993 war in Croatia

Ninety soldiers with at least three months of combat exposure—60 injured soldiers (30 with permanent disabling and 30 with nondisabling injuries), 30 noninjured soldiers and 30 healthy controls—were interviewed and investigated with physiological (Prolactine, Cortisol, BP, Hb) and psychological tests (MMPI), IES-15 (Impact of Event Scale), PTSS (Post-Traumatic Symptom Scale). Their was related injuries had a different effect on the physiological stress response of the soldiers as reflected in the levels of prolactine, cortisol, hemoglobin and blood pressure. In a report of personality characteristics of the same soldiers, we demonstrated that the experience of posttraumatic stress was not dependent upon physical injury, but rather on the psychological appraisal of the situation. The results of the present article confirm earlier findings that the relationship between physiological and psychological consequences of trauma are complex, and that the perception of an event and the social context within which the traumatized soldier exists is as important as the event itself. The physiological response to the trauma varied greatly among the soldiers regarding the psychosocial impact of the consequence of the injury. So the anticipation of future possible trauma among less severely wounded soldiers (expected to go back to war) was followed by pathological stress responses. Trauma seems to operate somewhat independently from the overt conscious appraisal of the situation and relationship between psychological, psychosocial, and physiological aspects are interrelated in a multifactorial way. An integrative approach is therefore of great importance in assessment as well as in treatment of Posttraumatic Stress Disorder (PTSD). Editorial Note This historical article is being published for the first time. It is based on the Ph.D. thesis of Dr. Harry A. Teitelbaum for which he was awarded a doctorate by the University of Maryland in College Park in 1936. The dissertation was stored prior to publication and was not rediscovered until 1997. Teitelbaum’s work was performed during the early days of the development of knowledge regarding the mechanisms that regulate endocrine function. The understanding of the broad capability of interactions among endocrine glands was evolving. It was a field that Teitelbaum contributed to for several years, many of which were spent in collaboration with Horsley Gantt in his laboratory at Johns Hopkins. Although some of the experimental strategies and some of the wording of the report seem quaint today, the contribution of Teitelbaum’s research was solid and highly relevant to questions being asked at the time.     

An empirical couple typology based on differentiation

Both spouses of 100 married, heterosexual couples completed the Personal Authority in the Family System Questionnaire (PAFS-Q). A cluster analysis of the couples' scores on the four intimacy and fusion scales of the PAFS-Q produced four clusters that were meaningfully distinct in the patterns of differentiation of the wives and husbands. Couples comprising these clusters are described in terms of intergenerational theories of family interaction.This paper is based on the master's thesis of the first author submitted to the Graduate School of Texas Woman's University. A presentation based on this work was given at the 1988 annual convention of the Southwestern Psychological Association, Tulsa, Oklahoma. The authors thank Glenda Peters and Joe Natale for their contributions to the preparation of this paper. A more extensive report of the methodology and results of this study can be obtained from the second author.     

閃光信号的頻率选择实驗研究

一、問題 在現代生产技术中,人和机器可以看作是一个統一的系統。这一系統的中心环节是人。人凭借自己的感官从仪表和信号得到有关机器的运轉状态和生产过程的变化的信息,經过一系列的思惟活动,然后作出判断,并通过操作活动对机器和生产过程进行控制和調节。关于人和机器的这一方面的关系,以及关于机器、仪表、信号和操纵装置的設計如何适应人的感知、思惟和运动的特点,以便使“人机系統”达到最高效率的研究,已經形成一个新的学科分支,即“工程心理学”。本研究所涉及的閃光信号的頻率选择問題,就是属于工程心理学的范围。     

关于汉語拼音方案中的省略字和一些变化規則的研究

一、汉語拼音方案的科学性及优越性 汉語拼音方案是利用拉丁字母和北京音組織起来的中国化的文字的基础。汉語拼音字母中的复韵母和鼻韵母是由两个或两个以上的单韵母組成的。除开带ng的鼻韵母本身較难拼音之外其余的复韵母本身都可以进行拼音的。所以在拼音字母中,只要掌握26个(实际应用是25个)名称音的字母之后,其余的复韵母和鼻韵母几乎都可以利用邏輯記忆     

药品带量采购的阻力、压力与垄断力问题探讨

带量采购是深化三医联动改革的重要尝试,药品集采作为医保改革的抓手试图撬动医疗及医药领域改革,为持续推进医疗卫生制度改革走向深入带来一线曙光。带量采购政策本质上涉及不同利益的再分配,藉由政府宏观调控及微观规制手段,最终实现药价降低、群众普惠的效果。基于对带量采购的理论分析及目前试点过程中存在的阻力、压力与垄断力问题,提出平衡理念为带量采购助推三医联动改革走向深远提供了一种思路。

     

消费决策中羊群行为的启发式加工及产生根源

消费决策中的羊群行为是消费市场上的一种典型现象.它是指在不确定情境中,消费者模仿他人进行消费决策的行为.本研究通过两个实验逐步揭示了消费决策中羊群行为的产生根源.实验1研究表明,消费决策中的羊群行为是消费者利用一致性启发式或能力启发式加工信息的结果.实验2通过内隐联想测验进一步研究表明,个体使用两种启发式的原因在于消费者对大众和专家的刻板印象:他们总是认为大众和专家的决策是正确的.
