Response latencies in the yes/no detection task: An assessment of two basic models

Two general forms of model for response latency in the yes no signal detection task are described and their predictions examined in the light of experimental data. One model supposes a latency function along the detection axis and the other supposes that a count is made of multiple observation, Experiment I looks at the auditory detection situation with short observation interval, but the results are generally equixocal, although the latency function model gives a simpler interpretation Other results are then discussed, particularly those of Gescheider et al (1969). and it is concluded that an attempt must be made to replicate the results of Carterette et al (1965) for the extended observation interval detection experiment. This is achieved in Experiment II. and the obtained order of mean latencies is then examined in terms of the models The counting model appears by far the more suitable for this situation.     

The latencies of correct and incorrect responses in discrimination and detection tasks: Their interpretation in terms of a model based on simple counting

A model for two-choice discrimination based on a process of simple counting is described, and two experiments are performed to test the predictions of the model concerning the graph of latency as a function of response proportion. Two main forms of this graph are identified and predicted to arise in different circumstances. The experimental results support the model, and its possible extension to other psychophysical situations, especially signal detection, are then discussed. It is compared with a model derived directly from the detection situation, and the usefulness of testing these models is pointed out.     

Work and nonwork stressors,negative affective states,and pain complaints among firefighters and paramedics

Prior research has suggested that occupational stressors may contribute to the etiology, progression, and chronicity of pain problems in workers. This study used anonymous survey methods to assess the prevalence and frequency of self-reported pain symptoms and their relationships to demographic variables, sources of occupational stressors, nonwork stressors and affective distress in a large sample (N2000) of employed career public sector firefighters and paramedics. The findings were consistent with those of previous studies of high strain workers. More than 95% of the firefighter/paramedic sample reported at least one pain complaint (using a 1 week assessment time frame). A hierarchical multiple regression analysis entering demographic, occupational, and nonwork stressors, as well as measures of negative affective states targeting total pain scores, yielded significant relationships. Five occupational stressors were associated with respondent pain complaints. The results also suggest that negative affective states mediated the relationships between work and nonwork variables, and pain complaint outcomes. The implications of these findings for the development of preventive interventions for firefighters and paramedics as well as other emergency service workers are considered.     

内隐关系评估程序(IRAP)：测量原理及应用

内隐关系评估程序(Implicit Relational Assessment Procedure, 简称IRAP)是基于关系结构理论直接测量社会认知、信念或态度的新内隐测量方法, 具备一定的可靠性和有效性, 并与其它相关测量方法的适用性存在一定差异。不同的理论模型为IRAP的不同效应提供了解释。IRAP最初应用于临床诊断性研究, 新近已扩展到自我、社会认知、群体和态度等研究领域。进一步验证不同形式IRAP的信效度、探究IRAP的心理机制及产生的心理效应、在不同领域发挥IRAP的方法优势等将是未来研究的重要方向。     

EMPLOYEE SELF-SERVICE TECHNOLOGY ACCEPTANCE: A COMPARISON OF PRE-IMPLEMENTATION AND POST-IMPLEMENTATION RELATIONSHIPS

Implementation of employee self-service (ESS) technology presents a variety of challenges for organizations as they strive to maximize return on investment and change management. Using a research framework grounded in the theory of planned behavior, this study examines factors that enhance user acceptance of ESS technology both before and after implementation. Results suggest that employees are more likely to intend to use ESS technology when they have positive attitudes toward using it and when subjective norms in the organization support use of the technology. Perceived organizational support (POS) enhanced the effect of managerial pressure on perceptions of normative beliefs supporting use of the technology post-implementation. Implications of the research and future research directions are discussed.     

《乾卦》爻辞中星宿信息钩沉

先贤用天象来解释乾卦六龙,但由于未涉及具体的星宿证据,不能断定乾卦爻辞只能来自与苍龙有关的天象。本文发现乾卦爻辞中按天象出现的先后顺序,除了容易被泛哲理化解释的“龙”之外,还隐含着五个星宿信息,即天田、健闭、天渊、鱼、天渊,因此可断言这些爻辞的原型来自天象。     

流动儿童的问题行为与人格、家庭功能的关系

以北京市806名流动儿童和319名城市儿童为被试,采用问题行为问卷、小五人格问卷和家庭功能问卷,考察流动儿童问题行为的特点及其与城市儿童的差异,并探讨人格和家庭功能对流动儿童问题行为的影响。结果发现:(1)流动儿童内、外化问题行为的自我报告率分别达到了31.0%2、0.1%,与城市儿童相比,流动儿童的内化问题行为较为突出。(2)人格的情绪性、开放性显著正向预测流动儿童的内化问题题行为,外向性、家庭功能的亲密度显著负向预测其内化问题行为,情绪性、开放性显著正向预测流动儿童的外化问题行为,宜人性、谨慎性、亲密度显著负向预测外化问题行为。(3)人格在家庭功能的亲密度与内化问题行为之间起部分中介作用,在亲密度与外化问题行为之间起完全中介作用。     

Spirituality,Morality and Poetry

This paper illustrates how poetry can play a major role in facilitating adolescents' spiritual and moral development. Examples are given of adolescents' responses to poems, when the pedagogy they experienced was influenced by reader response theory, to illustrate the seminal value of this genre and teaching methodology in fostering spiritual and moral reflection and growth. The link between poetry, spirituality and morality is examined with reference to writers in the field of literature. Finally, selected findings from a 3-year longitudinal case study of readers' responses to poems are reported to illustrate conclusions drawn concerning the value of poetry in the education of the whole person.     

Does the presentation of multiple facial composites improve suspect identification?

Previous research that has evaluated the accuracy of facial composites has reported low identification rates. Two studies are reported here that consider whether showing more than one composite of the same suspect might improve the rate of identification. Sixteen participant‐witnesses saw one of two staged events, each involving a different unfamiliar target. Each participant‐witness worked with a police operator to construct a composite of the target they had seen. One, four or eight composites depicting the same target were then shown to individuals familiar with the target. Overall, the results showed that presenting more than one composite increased the rate of identification. In addition, the results of Study 2 suggest that if the police must select just one composite from a number produced by witnesses, then a promising method might be to choose the one which bears most similarity to the other composites in the set.
