材料因素对学习判断及其孤立效应的影响

通过三个实验考察材料特有的内在因素差异对学习判断及其孤立效应的影响,选取814名的高一学生作为被试,男女各半。实验一是探讨性质不同的孤立项目对学习判断及其孤立效应的影响;实验二是探讨层次差异不同的同质项目对学习判断及其孤立效应的影响;实验三是探讨孤立项目的序列位置对学习判断及其孤立效应的影响。结果表明:在不同材料中,材料的性质的差异越大,孤立效应越显著,证明了孤立材料的距离效应;在同质材料中,材料内部层次差异越大,孤立效应越显著,证明了孤立材料的幅度效应;在学习判断中,不管孤立项目的序列位置处于前位还是后位,都存在孤立效应,且材料中孤立项目的位置越靠后面,其孤立效应就越明显,证明了孤立材料的后位效应。     

Development of a Cyber/Information Technology Knowledge Test for Military Enlisted Technical Training Qualification

An Armed Services Vocational Aptitude Battery (ASVAB) Review Panel, with expertise in personnel selection, job classification, psychometrics, and cognitive psychology developed recommendations for changes to the military enlistment test battery. One recommendation was to develop and evaluate a test of cyber/information and communications technology literacy to supplement current ASVAB content. This article summarizes a multiphased Cyber Test development process: (a) a review of information/computer technology literacy definitions and measures, (b) development and pilot testing of a cyber knowledge measure, (c) validation of test scores against final school grades (FSGs) for selected technical training courses, (d) development of an operational reporting metric and subgroup norms, and (e) examination of construct validity. Results indicate the Cyber Test has predictive validity versus technical training school grades and incremental validity comparable to the ASVAB technical knowledge tests when used with the ASVAB Armed Forces Qualification Test (AFQT) verbal/math composite as a baseline.     

晚期乳腺癌外科治疗的时机与个体化选择

IV期乳腺癌是难以治愈的疾病,治疗方法是综合治疗,目的是缓解症状、改善生活质量、延长生存期。外科治疗作为综合治疗的一部分,对手术切除Ⅳ期乳腺癌原发灶或转移灶的临床意义和手术时机存在争议,本文结合文献从哲学的角度分析讨论Ⅳ期乳腺癌是否需要外科处理。认为Ⅳ期乳腺癌全身治疗和外科治疗是治疗过程中矛盾主要方面和次要方面的关系,可互相转化,两者作用相辅相成,当全身治疗病情缓解时,个体化选择外科治疗不仅改善生存质量,还可能提高生存率。     

Individual Differences in Situation Awareness: Validation of the Situationism Scale

This article concerns the construct of lay situationism—an individual’s belief in the importance of a behavior’s context. Study 1 identified a 13-item Situationism Scale, which demonstrated good reliability and validity. In particular, higher situationism was associated with greater situation-control (strategies to manipulate the environment in order to avoid temptation). Subsequent laboratory studies indicated that people higher on the situationism subscales used greater situation-control by sitting farther from junk food (Study 2) and choosing to drink non-alcoholic beverages before a cognitive task (Study 3). Overall, findings provide preliminary support for the psychometric validity and predictive utility of the Situationism Scale and offer this individual difference construct as a means to expand self-regulation theory.     

Greater exposure to sexual content in popular movies predicts earlier sexual debut and increased sexual risk taking

Early sexual debut is associated with risky sexual behavior and an increased risk of unplanned pregnancy and sexually transmitted infections later in life. The relations among early movie sexual exposure (MSE), sexual debut, and risky sexual behavior in adulthood (i.e., multiple sexual partners and inconsistent condom use) were examined in a longitudinal study of U.S. adolescents. MSE was measured using the Beach method, a comprehensive procedure for media content coding. Controlling for characteristics of adolescents and their families, analyses showed that MSE predicted age of sexual debut, both directly and indirectly through changes in sensation seeking. MSE also predicted engagement in risky sexual behaviors both directly and indirectly via early sexual debut. These results suggest that MSE may promote sexual risk taking both by modifying sexual behavior and by accelerating the normal rise in sensation seeking during adolescence.     

Relationship Development in Selling: A Cognitive Analysis

Recent research has suggested that trust and relationship-building contribute to the effectiveness of salespeople. This paper reviews the literature on the cognitive selling paradigm and the influence of knowledge structures on the relationship-building process. Next, two recent studies (Anglin 1990; Szymanski 1987) which investigated knowledge, relationship development, and sales performance are reviewed. The findings from these studies imply that a fundamental difference may exist in the manner in which higher and lower performing salespeople perceive the selling process. Higher performers placed greater emphasis on establishing “trust” and also preferred to find out information about the prospect before reciprocating with information about themselves. Lower performers, on the other hand, preferred to disclose information about themselves before obtaining personal information about the prospect.     

Racial disparities in smoking knowledge among current smokers: Data from the health information national trends surveys

Although African-Americans (Blacks) smoke fewer cigarettes per day than European-Americans (Whites), there is ample evidence that Blacks are more susceptible to smoking-related health consequences. A variety of behavioural, social and biological factors have been linked to this increased risk. There has been little research, however, on racial differences in smoking-related knowledge and perceived risk of lung cancer. The primary goal of the current study was to evaluate beliefs and knowledge that contribute to race disparities in lung cancer risk among current smokers. Data from two separate nationally representative surveys (the Health Information National Trends surveys 2003 and 2005) were analysed. Logistic and hierarchical regressions were conducted; gender, age, education level, annual household income and amount of smoking were included as covariates. In both studies, Black smokers were significantly more likely to endorse inaccurate statements than were White smokers, and did not estimate their lung cancer risk to be significantly higher than Whites. Results highlight an important racial disparity in public health knowledge among current smokers.     

Standing Out From the Crowd: How Comparison to Prototypes Can Decrease Health-Risk Behavior in Young Adults

This research tested whether social comparison can encourage adolescents to make less risky health decisions. Two studies demonstrated that when young adults compare themselves with drinkers, they become less willing to drink if they perceive dissimilarity between themselves and those drinkers. When participants in Study 1 compared with someone who drinks regularly, their perceived similarity to prototypical drinkers was positively related to their willingness to drink. In Study 2, participants identified or contrasted themselves with prototypical drinkers; those encouraged to contrast who also felt less similar to the prototype reported less willingness to drink. These studies support the prototype/willingness model's assumption that prototypes affect willingness to drink through social comparison.

现实预期与意愿预期在文本阅读中的保持

文本阅读中, 读者往往对事件的后续发展进行预期推理。预期推理有两种倾向, 要么是倾向于根据客观现实条件进行的现实预期, 要么是倾向于根据主观的个人意愿进行的意愿预期。3个实验通过自定步调阅读范式探讨了文本阅读中读者产生的现实预期和意愿预期的保持。结果发现, 现实预期和意愿预期在长时记忆中的保持情况差异明显, 现实预期不能在长时记忆中保持, 而意愿预期则能保持; 但意愿预期也不能单独存在, 会受到现实条件的制约, 在受到现实否定后即时消退, 不再影响读者的进一步阅读。
