Influence of Psychological Contract Breach on Organizational Citizenship Behaviour and Trust

The present research intends to understand the influence of employee’s perception of psychological contract breach on their organizational citizenship behaviour and trust on employers. The study was carried out in private banks of North Delhi. Data were gathered from 90 junior level executives using convenience sampling method. Result revealed that psychological contract breach significantly predicts organizational citizenship behaviour and trust. The findings imply that the organization needs to understand and manage employee’s psychological contract properly otherwise perception of its breach can jeopardize employee’s citizenship behaviour and also their trust in employer which in turn may affect their job performance.     

临床教学中运用标准化病人的困境及对策——以南京医科大学为例

本文介绍了国内高等医学院校标准化病人(SP)工作的基本情况,并以南京医科大学为例阐述了在临床教学过程中SP工作不同发展阶段,结合有关文献梳理出当前SP工作诸如对SP的认识尚不完全统一、对SP工作的评价标准有异、SP队伍不稳定影响持续发展、应用范围太窄影响SP投入产出效益及SP工作的条件保障难以满足发展需要等问题,结合研究提出了加大对SP的宣传;加大SP项目的协作;加大SP权益保护;加大SP开放性探索及增强经费资源的投入力度等建议.     

功能性胃肠病诊断方法现状分析

功能性胃肠病是一种存在消化道症状,但无法用器质性病变或生化异常来解释的消化道功能性疾病.在消化系统疾病中发病率非常高,严重影响了人们的生活质量.目前临床诊断功能性胃肠病主要依据国际公认的以症状学为诊断依据的罗马Ⅲ诊断标准.但因其病因、发病机制以及病理生理基础并未完全明确,罗马Ⅲ并不是诊断的完美金标准.针对这些环节,国际国内开展了各种各样的检查方法.笔者综述了目前临床上常用的诊断方法以及存在的主要问题,以期协助指导临床诊断及治疗.     

The involuntary nature of music-evoked autobiographical memories in Alzheimer's disease

The main objective of this paper was to examine the involuntary nature of music-evoked autobiographical memories. For this purpose, young adults, older adults, and patients with a clinical diagnosis of probable Alzheimer's disease (AD) were asked to remember autobiographical events in two conditions: after being exposed to their own chosen music, and in silence. Compared to memories evoked in silence, memories evoked in the "Music" condition were found to be more specific, accompanied by more emotional content and impact on mood, and retrieved faster. In addition, these memories engaged less executive processes. Thus, with all these characteristics and the fact that they are activated by a perceptual cue (i.e., music), music-evoked autobiographic memories have all the features to be considered as involuntary memories. Our paper reveals several characteristics of music-evoked autobiographical memories in AD patients and offers a theoretical background for this phenomenon.     

An R package for state-trace analysis

State-trace analysis (Bamber, Journal of Mathematical Psychology, 19, 137-181, 1979) is a graphical analysis that can determine whether one or more than one latent variable mediates an apparent dissociation between the effects of two experimental manipulations. State-trace analysis makes only ordinal assumptions and so, is not confounded by range effects that plague alternative methods, especially when performance is measured on a bounded scale (such as accuracy). We describe and illustrate the application of a freely available GUI driven package, StateTrace, for the R language. StateTrace automates many aspects of a state-trace analysis of accuracy and other binary response data, including customizable graphics and the efficient management of computationally intensive Bayesian methods for quantifying evidence about the outcomes of a state-trace experiment, developed by Prince, Brown, and Heathcote (Psychological Methods, 17, 78-99, 2012).     

内在锚与外在锚对锚定效应及其双加工机制的影响

通过2（外在锚类型：高锚VS低锚）×2（内在锚类型：有VS无）被试间设计,考察不同锚定信息来源：由外部世界提供的外在锚与个体自身内部产生的内在锚信息对锚定效应及其加工机制的影响。结果发现：（1）当内在锚不存在时,外在高低锚组的估计值有显著差异,当内在锚存在时此种差异变得不显著;（2）当内在锚存在时,外在高低锚组被试的答题反应时有显著差异,内在锚与外在锚一致时反应时比不一致时更快,当内在锚不存在时,此种差异变得不显著。实验结果表明,当锚定调整机制与选择通达机制同时存在时,前者更占优势;锚定信息一致性会影响不同加工机制的启动,一致的信息会激活选择通达机制,不一致的信息则会激活锚定调整机制。     

习惯研究的现状与展望

习惯是一种由某特定线索引发并指向某特定目标(包括外显目标与内隐目标)的自动化反应。它具有过去有行为的重复、环境线索的稳定与自动化的反应等特征。关于习惯的测量方式主要采取自我报告法（如自我报告过去行为频率、自我报告习惯频率、自我报告习惯索引等）和反应频率测量法。对习惯的形成的理论解释主要有环境促进、态度促进、目标促进等几种观点。未来研究应继续深入探讨习惯的本质、整合形成机制的相关理论及开发更可靠方便的测量工具。     

A naturalistic study of prospective memory in preschoolers: The role of task interruption and motivation

We conducted two naturalistic experiments to investigate preschoolers’ development of event-based prospective memory (PM) and to examine the effects of motivation and interruption of an ongoing task. Children aged 2–6 years were asked to perform familiar PM tasks while engaged in their habitual kindergarten play. PM performance improved systematically across the preschool years. The type of PM response (motor or verbal) did not affect performance. High motivation was necessary for 2-year-olds to perform well, and it remained an important factor that increased performance across the entire preschool age range. The need to interrupt an ongoing activity decreased performance in 3-, 4-, and 5-year-olds, but not in children aged 2 or 6 years. The pattern of results is consistent with explanations for interruption effects that highlight the role of inhibitory control.     

In situ characterization of the martensitic transformation temperature of NiTi shape memory alloys via instrumented microindentation

A novel, instrumented microindentation technique was successfully used to measure the temperature associated with the martensitic transformation leading to the recovery of plastic strain in a Nickel–Titanium (NiTi) shape memory alloy. Following a standard indentation cycle, the indenter was partially unloaded such that a good contact was maintained between indenter and specimen surface. The onset and finish temperature of the martensitic transformation, the associated volume contraction, and the amount of the recovered plastic deformation were determined by quantifying the indenter displacement as a function of temperature. These experiments were compared to conventional measurements of the transformation temperature by differential scanning calorimetry and compression testing.     

Alexithymia and the interpretation of emotion-relevant information

Abstract

This study examined the relationship between alexithymia and (a) hemis-patial bias; (b) the accuracy of interpreting emotion-relevant information; and (c) the style of interpreting emotion-relevant information. Subjects were 137 college students. Alexithymia was measured using the Toronto Alexithymia Scale. Hemispatial bias was measured using a free-vision chimeric face task. Interpretations of emotion-relevant information were assessed using the Profile of Nonverbal Sensitivity (PONS) and a second instrument designed for this study called the Emotional Story Test (EST). Although high levels of alexithymia were associated with hemispatial bias, alexithymia was not associated with the accuracy of subjects' interpretations. In contrast, alexithymia was associated with low ratings of emotional intensity and with subjects' inclinations to choose angry and dominant interpretations.
