Tuberculosis detection by giant african pouched rats

In recent years, operant discrimination training procedures have been used to teach giant African pouched rats to detect tuberculosis (TB) in human sputum samples. This article summarizes how the rats are trained and used operationally, as well as their performance in studies published to date. Available data suggest that pouched rats, which can evaluate many samples quickly, are sufficiently accurate in detecting TB to merit further investigation as a diagnostic tool.     

Lack of sleep and unethical conduct

We draw from the Ego Depletion model and research on sleep physiology to predict a relationship between lack of sleep and individuals’ unethical behavior. Laboratory studies showed that sleep quantity is positively related to self-control resources and negative associated with unethical behavior. In a cross-sectional field study examining unethical behavior in a variety of work settings, low levels of sleep, and low perceived quality of sleep, were both positively related to unethical behavior as rated by the supervisor, and cognitive fatigue mediated the influence of sleep quantity. In an experience sampling field study, we found similar effects within-individuals. We discuss the role of lost sleep in better understanding unethical behavior in organizations.     

幼儿基于信息判断的选择性信任——与亲社会行为及决策判断的关系

选择性信任指人们在面对不同信息传达者时,能依据信息的正误区分出他们的可信赖度,从而有选择地相信某些传达者。本研究探讨幼儿选择性信任与亲社会行为及决策判断的关系。研究一以75名3～4岁幼儿为研究对象,采用选择性信任任务与分配糖果任务相结合的模式,探讨亲社会行为与选择性信任的关系,发现3～4岁幼儿在选择性信任形成后,亲社会倾向更多地指向可信赖者。研究二关注选择性信任与幼儿的决策判断的关系,在对72名3～4岁幼儿的研究中发现,在众多颜色糖果的选择中,相对于对照组的均等偏好,实验组的3～4岁幼儿决策判断明显受到可信赖者的影响,即更倾向于选择可信赖者推荐的颜色糖果。     

中学生攻击性行为的注意偏向与冲动控制特征

通过注意偏向实验、BPAQ攻击问卷与Barratt冲动量表的施测,探讨中学生攻击性行为的注意偏向与冲动控制特征。研究结果发现,中学生攻击性行为及冲动控制性别差异不显著;低攻击性与高攻击性中学生表现出对攻击性刺激的注意偏向特征,在冲动控制上差异也极其显著;中学生攻击性行为与注意偏向、冲动控制总体上呈显著正相关;攻击词注意偏向与冲动控制对中学生攻击性行为具有显著预测作用。     

组织政治知觉对组织认同的影响及工作投入的中介作用

以300余名中国大陆制造业企业的员工为被试,运用问卷调查方法和分层回归分析对组织政治知觉、组织认同和工作投入的关系进行了探讨。结果发现：（1）组织政治知觉对工作投入和组织认同有直接的消极影响;（2）组织政治知觉通过组织认同的中介对工作投入有间接的消极影响;（3）在组织政治知觉的三个子维度中,只有薪酬与晋升子维度对工作投入和组织认同具有显著影响。     

Bridging the intention–behavior gap: Inducing implementation intentions through persuasive appeals

The potential of using implementation intentions—action plans that link a critical situational cue to a specific goal-directed behavior—to bridge the intention–behavior gap in consumer behavior has been limited by the practice of using explicit instructions to induce the construct. In two studies, we therefore tested the effectiveness of an indirect, persuasive strategy that benefits from the positive consequences of implementation intentions by ‘mimicking’ their underlying psychological processes. Experiment 1 showed that a strategy presenting vivid information on critical cues and appropriate behavioral responses affected mental imagery. Experiment 2 demonstrated that this strategy affected actual purchase behavior.     

Delivering Parent-Child Interaction Therapy in an Urban Community Clinic

Extensive evidence supports the efficacy of Parent-Child Interaction Therapy (PCIT) for reducing behavior problems in young children; however, little is known about the use of PCIT in a community mental health center (CMHC). This paper provides four clinical case examples of families who were referred to and successfully completed PCIT in an urban CMHC. The families were ethnically and socioeconomically diverse and presented with a wide range of treatment concerns and needs (e.g., autism, severe maternal psychopathology, involvement in child protective services, and complex family configurations) in addition to disruptive behavior. Our data and clinical observations suggest that PCIT decreased behavior problems, improved parent-child interactions, and, in some cases, reduced parental stress, with differing levels of change across families. Overall, the cases demonstrate that PCIT can be transported into a CMHC, and they illustrate supplemental services or minor accommodations to the established treatment protocol used to address individual family needs. Issues regarding the balance between fidelity and flexibility in transporting PCIT to a community setting are discussed, and future research topics are recommended.     

时限性自我调节理论:健康行为研究的一种新取向

时限性自我调节理论是在“意图-行为”模型基础上,强调时间、行为优势和自我调节能力对健康行为共同影响的新理论.该理论认为一致性观念和时限性效价影响行为意图,行为优势和自我调节能力调节“意图-行为”联系的强度或直接影响行为.与其他健康行为模型的主要区别在于加入了影响行为的自我调节能力和时间因素.未来研究应进一步明确针对健康行为的干预措施,给予行为优势合理的定位.     

高校毕业生求职行为的影响机制研究

基于计划-行为理论,考察了836名高校毕业生求职行为的预测因素及其影响机制。层次回归和结构方程分析表明,控制了城乡和政治面貌的效应后,求职自我效能、求职期望、情绪控制、人格外倾和主观支持是影响求职行为的有效因素,其中求职自我效能、情绪控制、人格外倾和主观支持分别正向预测求职行为,而求职期望则负向预测求职行为;求职意向在求职期望和求职行为、情绪控制和求职行为、主观支持和求职行为之间的中介效果均显著,在求职自我效能和求职行为以及人格外倾和求职行为之间的中介效果不显著。
