Manual discrimination of force using active finger motion.

In these experiments, two plates were grasped between the thumb and forefinger and squeezed together along a linear track. An electromechanical system presented a constant resistance force during the squeeze up to a predetermined location on the track, whereupon the force effectively went to infinity (simulating a wall) or to zero (simulating a cliff). The task of the subject was to discriminate between two alternative levels of the constant resistance force (a reference level and a reference-plus-increment level). Results of these experiments indicate a just noticeable difference of roughly 7% of the reference force using a one-interval paradigm with trial-by-trial feedback over the ranges 2.5 less than or equal to F0 less than or equal to 10.0 newtons, 5 less than or equal to D less than or equal to 30 mm, 45 less than or equal to S less than or equal to 125 mm, and 25 less than or equal to V less than or equal to 160 mm/sec, where F0 is the reference force, D is the distance squeezed, S is the initial fingerspan, and V is the mean velocity of the squeeze. These results, based on tests with 5 subjects, are consistent with a wide range of previous results, some of which are associated with other body surfaces and muscle systems and many of which were obtained with different psychophysical methods.     

Self-compassion reduces parental burnout: Mediation roles of parental psychological control and support

This study investigated the mediating role of parental psychological control (PPC) and support in the relationship between self-compassion and parental burnout syndrome. The study participants included 1185 Vietnamese parents who completed questionnaires regarding demographic information, parental burnout, self-compassion, parental support of the child, and PPC. We used data analyses, including structural equation modeling, to test the mediation roles of PPC and parental support of the child. Our main findings include: (1) self-compassion had a significant negative effect on parental burnout; (2) the mediation roles of PPC and parental support of the child were also significant. These results suggest that parents with high self-compassion tend to provide more support for children in daily parenting, which helps reduce parental burnout. In contrast, parents with low self-compassion were more likely to use PPC, which exacerbated their burnout. The results from this study provide suggestions for creating effective interventions in the family context to reduce parental burnout and improve parenting effectiveness.     

Reward Expectations: The Influence of Race, Gender and Type of Job

Previous research on pay expectations has focused on gender differences and the reasons for those differences. In this study three types of reward expectations were measured. Pay expectations (starting salary and peak salary) were assessed, as well as another reward expectation, ease of promotion. The influences of gender, race, and type of job on reward expectations were investigated. The results indicated that Caucasians have higher peak pay expectations than African Americans for all job types. Interactions were discovered between race and type of job for starting salary, and between gender and type of job for ease of promotion.     

宋代度僧制度再考辨

宋代度僧,承袭唐、五代旧制,历经了由注重培养僧尼素质到重视国家经济收益的政策转型。从形式上看,主要采取试经、恩度和进纳三种方式,其中试经为正途,恩度为特殊荣宠,进纳为用钱买牒;从特点上看,呈现出了完善差官制度、规范应试程序、严明考试资格的特质;从影响上看,宋代度僧制度在一定程度上巩固了赵宋王朝的统治,为宋以降佛教制度的完善和发展创造了前提。如是,宋代度僧制度已经形成了一套相对周备的僧籍管理轨制,既揭示了宋代统治者对佛教的政策,又对研究宋史和中国佛教史有着重要的鉴戒意义。     

Improving judgment accuracy by sequential adjustment

Judging an object’s value based on relevant cues can be challenging. We propose a simple method to improve judgment accuracy: Instead of estimating a value after seeing all available cues simultaneously, individuals view cues sequentially, one after another, making and adjusting their estimate at each step. The sequential procedure may alleviate computational difficulties in cue integration, leading to higher judgment accuracy. We tested this hypothesis in two real-world tasks in which participants judged either the price of diamonds or the fuel economy of cars. Two studies with professional jewelers and car salespeople show that most participants indeed judged more accurately with a sequential than with a simultaneous procedure. Another two studies with college students further support this finding and show additionally that the sequential procedure could raise the judgment accuracy of inexperienced students to the same level as that of professionals judging with the simultaneous procedure.

     

Temporary employees in Singapore: what drives them?

In this study the authors provide an empirical analysis of the job attitudes and behavior of temporary workers in Singapore, compiling and categorizing the various reasons individuals choose temporary jobs, in an effort to provide a clear and comprehensive understanding of why people choose this work arrangement. A profile of temporary employees showed that job attitudes are affected by the importance of the various reasons given for being a temporary worker. This exploratory study provides a foundation on which more complex relationships between these variables can be examined.     

An attempt to discriminate different types of executive functions in the Wisconsin Card Sorting Test

This study examined the roles of the phonological working memory and the central executive in the Wisconsin Card Sorting Test by altering the materials and the procedure of the task and using a dual-task design, in which cognitive abilities of normal participants were manipulated by performance of the secondary tasks selectively taxing the phonological loop or the central executive. The present study used three novel versions of the Wisconsin Card Sorting Test, namely the WCST-4 stimuli, the WCST-12-stimuli, and the WCST-12-stimuli-box, in all of which the participants were given the exact sorting criterion. So the tasks did not involve processes such as maintenance of inferences about the sorting criterion which would require phonological memory load. However, the tasks were assumed to require the executive process of response inhibition. In the WCST-4-stimuli condition no change was made to the WCST materials. In the other two conditions, relying on the assumption that the three-dimensional nature of the cards triggers inappropriate responses, unidimensional stimulus cards were used instead of the four normal three-dimensional WCST stimulus cards. The difference between these two conditions was that, in the WCST-12-stimuli-box condition, boxes were used to conceal the response cards previously sorted. The results supported Dunbar and Sussman's (1995) argument that some executive processes in the Wisconsin Card Sorting Test require the use of phonological store, and the present design was able to differentiate the type of executive functions that do not involve the use of a phonological loop from the ones that do. In addition, the results concerning manipulations of the visual aspects of the Wisconsin Card Sorting Test suggest that the three-dimensional nature of the WCST stimulus cards leads to an increase in the number of inappropriate responses produced with the executive secondary task interference.     

An exploratory study on the career anchors of educators in Singapore.

In this exploratory study, the authors adopted an empirical approach to determine the various primary career anchors possessed by Singapore educators, the impact of the degree of congruency between teaching and the career anchors on intrinsic and extrinsic satisfaction, and turnover intentions. A number of hypotheses were supported and provided the 1st step in understanding this group of important individuals who nuture the future generation of human capital for the workplace.     

忽视性阅读障碍的研究概况

首先介绍了忽视性阅读障碍(neglect dyslexia, ND)的概念,随后描述了ND病人在阅读过程中的表现,即衰减效应、词汇效应、词内区分效应、对称效应和词长效应以及保留的语义通达能力。尽管忽视症和ND可以分离,但两者之间有一定联系。文章最后对汉语ND的研究进行了分析和展望,认为其关键问题是阐明汉语ND在多大程度上与拼音文字ND具有可比性。
