组织承诺研究的进展与展望

该文采取多测度分析的方法,从理论基础,概念性定义和操作定义,量表的信度、效度和影响变量等方面对组织承诺的已有研究进行回顾和分析。发现现有的组织承诺概念比较冗余,需要进行有效的整合,现有组织承诺量表需要在内容效度、汇聚效度和区分效度等指标上进行深入探索;目前关于组织承诺的研究多从离职/留职意向的角度进行探讨,缺乏从雇佣关系的角度进行的系统研究;需要进行纵向研究以获得组织承诺和其他一些员工态度变量之间的因果关系;后续研究可以从中介变量和调节变量的角度,详细考察组织承诺的不同维度的交互作用。     

日常前瞻记忆的年龄差异

在年龄—前瞻记忆悖论现象中,老年人在完成日常前瞻记忆任务时,其表现优于年轻人的现象尤其引人注意。研究者一方面探讨了动机水平、责任心、生活状态以及外部帮助与提示等与主体有关的因素等对这一结果的影响;另一方面也研究了任务本身因素的影响,根据不同任务情境和任务性质的前瞻记忆年龄比较的结果,可以推断日常前瞻记忆年龄差异的来源在于任务的性质而非任务的情境。将来的研究可通过元分析、中介效应检验等手段进一步确定日常前瞻记忆年龄差异的机制。     

国内外职业承诺研究述评

从职业与事业的区别入手,对国内外职业承诺的概念、常用的几种职业承诺量表、职业承诺形成过程以及相关模型、前因与后果变量等方面的已有研究进行回顾和分析。研究发现,职业承诺与一些重要的效果变量有比较显著的关系,如职业满意度、工作投入、工作绩效等。文章最后指出了目前存在的问题及今后努力研究的方向,如现有的职业承诺概念比较凌乱,测量工具虽然多数是参照国外的重新编制,但其适用范围比较狭窄,因此需要对职业承诺的概念进行重新整合,职业承诺量表也需要对其在信效度指标上进行深入探索     

教师组织承诺结构的验证性因素分析

通过文献回顾、半结构访谈、问卷调查及理论分析,提出了教师组织承诺的结构。对278名教师进行测查以考察教师组织承诺的因素结构,验证了教师组织承诺的结构,发现教师组织承诺包含四个维度,即感情承诺、规范承诺、理想承诺和投入承诺。     

自我记忆的"错误"和"歪曲"

人们关于自我的记忆经常会发生“错误”和“歪曲”,造成这种状况的原因有三：其一是“压抑”,其二是“肯定性的错觉”,其三是“个体历史建构和保持”。它们是人们进行心理防卫的方式,其目的是使自我保持一种积极的、具有一致性和稳定性的状态。     

时间记忆中注意机制的研究

本文综述了时间记忆中注意影响机制的理论模型和研究范式，提出了进一步综合研究的设想和建立总的时间记忆注意模型的可能性。     

IT企业员工多层次承诺对离职意向的影响

IT企业的高离职率成为信息技术行业面临的一大难题,本研究运用问卷调查了浙江IT企业员工的多层次承诺(组织承诺、团队承诺和职业承诺)及其离职意向。结果发现,IT企业员工组织承诺是影响离职意向的重要因素;同时IT企业员工的团队承诺和职业承诺是组织承诺影响离职意向的缓冲变量。其中,团队承诺越高,组织承诺对离职意向的影响就越大;而职业承诺越低,组织承诺对离职意向的影响就越大。最后对IT企业的员工的管理提出了建议。     

Reversible Verbal Memory Integration Deficits in Obstructive Sleep Apnoea

When presented with novel but semantically related elements after learning verbal material, healthy participants tend to endorse these items as previously learned. This reflects the normal integration and association of novel verbal information into long-term memory. How obstructive sleep apnoea (OSA) negatively impacts verbal memory performance, and whether deficits are reversible following positive airway pressure (PAP) treatment, remain elusive. We investigated immediate and delayed OSA- and PAP treatment-related effects on verbal memory integration, using a false memory paradigm. Twenty-three patients with OSA learned lists of words semantically related to target non-presented words (1) at baseline after a polysomnography diagnosis night, (2) after a consecutive polysomnography night under PAP titration, and (3) after three months of compliant PAP treatment. At each session, participants learned 10 different lists of words, each list comprising 15 semantically related items. They had then to recognize 15 minutes later (after an intermediate vigilance task) previously learned words within a list including studied words (learned), unstudied but semantically related items (lures), and non-related unstudied items (controls). Sleep quality and fatigue questionnaires, and psychomotor vigilance tests (PVT) were administered at each session. PAP treatment led to OSA remission and improvement in objective and subjective sleep quality. Crucially, recognition of learned and lure words increased after the first night under treatment and remained stable three months later, suggesting successful memory integration and restoration of semantic processes. No treatment-related outcome was found on PVT performance. OSA exerts a detrimental but PAP-reversible effect on verbal learning and semantic memory integration mechanisms underlying the acquisition of novel memory representations.     

Memory and time

The purpose of this essay is to clarify the notion of mnemonic content. Memories have content. However, it is not clear whether memories are about past events in the world, past states of our own minds, or some combination of those two elements. I suggest that any proposal about mnemonic content should help us understand why events are presented to us in memory as being in the past. I discuss three proposals about mnemonic content and, eventually, I put forward a positive view. According to this view, when a subject seems to remember a certain event, that event is presented to her as making true a perceptual experience that caused the very memory experience that she is having.

Memory for temporally dynamic scenes

Recognition memory was investigated for individual frames extracted from temporally continuous, visually rich film segments of 5–15 min. Participants viewed a short clip from a film in either a coherent or a jumbled order, followed by a recognition test of studied frames. Foils came either from an earlier or a later part of the film (Experiment 1) or from deleted segments selected from random cuts of varying duration (0.5 to 30?s) within the film itself (Experiment 2). When the foils came from an earlier or later part of the film (Experiment 1), recognition was excellent, with the hit rate far exceeding the false-alarm rate (.78 vs. 18). In Experiment 2, recognition was far worse, with the hit rate (.76) exceeding the false-alarm rate only for foils drawn from the longest cuts (15 and 30?s) and matching the false-alarm rate for the 5?s segments. When the foils were drawn from the briefest cuts (0.5 and 1.0 s), the false-alarm rate exceeded the hit rate. Unexpectedly, jumbling had no effect on recognition in either experiment. These results are consistent with the view that memory for complex visually temporal events is excellent, with the integrity unperturbed by disruption of the global structure of the visual stream. Disruption of memory was observed only when foils were drawn from embedded segments of duration less than 5?s, an outcome consistent with the view that memory at these shortest durations are consolidated with expectations drawn from the previous stream.     

Memory and metamemory in obsessive-compulsive disorder

Studies on the link between checking and memory problems have produced equivocal results regarding a general memory deficit in patients with obsessive-compulsive disorder and subclinical checkers. However, there is clear and consistent evidence that patients with obsessive-compulsive disorder (OCD) show lack of confidence in their memory performance. The purpose of the present study was to investigate memory and metamemory performance (feeling-of-knowing judgments) for neutral and threat-related material in three groups: OCD patients (OCs), subclinical checkers (SCs), and normal controls (NCs). Participants studied a list of neutral and threat word pairs. After an initial cued-recall test, they provided feeling-of-knowing (FOK) judgments for unrecalled word pairs, followed by a recognition test. The results showed that OCs but not SCs were impaired in both recall and recognition compared to NCs. OCs were also less confident about their future memory performance than the other two groups, as reflected in their lower FOK ratings. Moreover, FOK judgments of the OCs were not reliable predictors of their recognition performance. Finally, neither OCs nor SCs showed any evidence of memory bias for threat-relevant information. The results support the idea of a general memory and a metamemory deficit in OCs.     

视觉感觉记忆在字音选取作业中的作用

该研究通过四项实验探讨了视觉感觉记忆(VSM)在字音选取作业中的作用。实验材料为48个汉字。实验结果表明:当被试只能利用短时记忆(STM)中的信息进行选取作业时,能选取的汉字数与转换到STM中的汉字数之间无显著性差异;当被试可以同时利用VSM和STM中的信息时,能选取的汉字数要显著多于转换到STM中的汉字数。这表明,人能根据字音特征从VSM信息中选取字符。     

Extended Memory Evolutive Systems in a Hyperstructure Context

This paper is just a comment to the impressive work by A. C. Ehresmann and J.-P. Vanbremeersch on the theory of Memory Evolutive Systems (MES). MES are truly higher order systems. Hyperstructures represent a new concept which I introduced in order to capture the essence of what a higher order structure is—encompassing hierarchies and emergence. Hyperstructures are motivated by cobordism theory in topology and higher category theory. The morphism concept is replaced by the concept of a bond. In the paper I briefly introduce hyperstructures motivated geometrically and suggest further developments of the MESs along these lines, which could widen up new areas of applications.     

公正世界信念对记忆偏差的影响

公正世界信念指人们需要相信他们所处的世界是一个公正有序的世界。本研究考察的是公正世界信念是否影响人们的记忆,让人产生记忆偏差。实验一中,被试首先阅读一则彩票中奖的新闻,然后阅读关于中奖者人品的描述,最后被试需要回忆中奖金额。结果发现,中奖者的个性品质影响对奖金数额的记忆。实验二中,两组被试分别阅读一则维护公正世界信念或威胁公正世界信念的无关故事,接下来程序与实验一相同。结果发现,预先激活的公正世界信念状态与中奖者个性品质在记忆结果上存在显著的交互效应。结果表明,公正世界信念能够导致记忆偏差。     

Memory systems within a cognitive architecture

This article addresses the division of memory systems in relation to an overall cognitive architecture. As understanding the architecture is essential to understanding the mind, developing computational cognitive architectures is an important enterprise in computational psychology (computational cognitive modeling). The article proposes a set of hypotheses concerning memory systems from the standpoint of a cognitive architecture, in particular, the four-way division of memory (including explicit and implicit procedural memory and explicit and implicit declarative memory). It then discusses in detail how these hypotheses may be validated through examining qualitatively the literature on memory. A quick review follows of computational simulations of a variety of quantitative data (which are not limited to narrowly conceived “memory tasks”). Results of accounting for both qualitative and quantitative data point to the promise of this approach.     

Memory for action events in the bottlenosed dolphin

We investigated whether a bottlenosed dolphin’s ability to recall and repeat actions on command would immediately generalize to actions performed with specified objects. The dolphin was tested on her ability to repeat 18 novel behaviors performed with potentially interchangeable objects specified using an artificial gestural language. Such “action events” were correctly repeated at above chance levels, indicating that the dolphin had access to memories of those events. Performance levels were, however, lower than in previous tests. The dolphin appeared to have difficulty recalling which object an action was performed with. Previous research has demonstrated that animals can recall features of their environment and features of their actions independently of one another. The results of this study demonstrate (1) that the dolphin’s concept of repeating extends beyond simply accessing memories of movement patterns, and (2) that dolphins’ memories of past events incorporate representations of both self-performed acts and objects, locations, or gestural instructions.
