创意实施——创新研究未来走向

创新一直是学术界关注和探讨的热点。过去40多年里, 有关创新的研究层出不穷, 取得了丰富的成果。然而, 这些研究主要集中在如何激发员工的创新行为上, 即创意产生这一环节。至于创意产生之后能否转化以及如何转化的问题没有引起足够的重视。创意是开端, 但需要把创意转变为现实, 否则创新难以转化为价值。研究创意实施的条件及其作用机制是推动创新研究深化的重要任务。目前已有的创意实施研究在研究层次和研究视角上都存在不足, 未来有必要在方法上把量化研究与质化研究结合起来, 从不同的层次和视角, 进一步拓展研究的范围, 揭示创意从产生到实施的条件和作用机制。     

代际工作价值观发展的研究述评

代际工作价值观的发展归结于社会文化的变迁。对代际工作价值观发展的研究契合了当前工作场所员工代际差异和冲突的研究趋势, 同时也有助于人们把握特定国家社会文化发展的脉络。这类研究是以“重大历史事件”作为划分“代”的主要标准, 以社会文化属性作为研究探讨的主要内容。目前, 多数西方的代际工作价值观研究发现, 西方国家的员工在工作中心化、利他观、内在工作价值观和外在工作价值观等方面呈现不同的发展规律。而我国由于社会历史文化的不同, 其发展趋势必然呈现不一样的特点。为此, 下一步的研究应在严格区别社会文化独特性的前提下, 采取合适的研究方法和“代”的划分标准, 重点研究工作价值观的“代单位”发展规律, 并拓展研究内容深度,特别是加强中国本土化研究力度, 这对于中国组织的人力资源管理有重要的借鉴价值。     

Take The First: Option-generation and resulting choices

Experimental decision-making research often uses a task in which participants are presented with alternatives from which they must choose. Although tasks of this type may be useful in determining measures (e.g., preference) related to explicitly stated alternatives, they neglect an important aspect of many real-world decision-making environments—namely, the option-generation process. The goal of the present research is to extend previous literature that fills this void by presenting a model that attempts to describe the link between the use of different strategies and the subsequent option-generation process, as well as the resulting choice characteristics. Specifically, we examine the relationship between strategy use, number and order of generated options, choice quality, and dynamic inconsistency. “Take The First” is presented as a heuristic that operates in ill-defined tasks, based on our model assumptions. An experiment involving a realistic (sports) situation was conducted on suitable participants (athletes) to test the predictions of the model. Initial results support the model’s key predictions: strategies producing fewer generated options result in better and more consistent decisions.     

基于语境的预期推理构建的实验研究

两个实验用移动视窗技术,用目标句阅读时间和命名探测词两种指标来考察当文本中有两个情境模型时,读者是否会即时进行预期推理。结果表明,如果在支持性语境与引发推理的信息之间插入一个与支持性语境所描述的情境模型不同的,且与主人公目标有关的因果链上的情境模型的信息,则不管这个插入的情境模型在文本中的位置如何,也不管干扰信息的干扰水平高低,都会降低因果性预期推理在阅读中产生的可能性。     

Equivalents for a Quasivariety to be Generated by a Single Structure

We present some equivalent conditions for a quasivariety of structures to be generated by a single structure. The first such condition, called the embedding property was found by A.I. Mal′tsev in [6]. It says that if are nontrivial, then there exists such that A and B are embeddable into C. One of our equivalent conditions states that the set of quasi-identities valid in is closed under a certain Gentzen type rule which is due to J. Łoś and R. Suszko [5].

Cognitive and Interpersonal Predictors of Stress Generation in Children of Affectively Ill Parents

Stress generation is a process in which individuals, through their depressive symptoms, personal characteristics, and/or behaviors, contribute to the occurrence of stressful life events. While this process has been well documented in adults, few studies have examined it in children. The present study examines whether cognitive and interpersonal vulnerability factors to depression contribute to stress generation in children, independent of their current depressive symptoms. Participants included 140 children (ages 6 to 14) and one of their parents. During an initial assessment, children completed self-report measures assessing cognitive and interpersonal vulnerability factors to depression. Children and their parents also completed measures assessing depressive symptoms. One year later, children and their parents participated in a semi-structured interview assessing the occurrence of stressful life events in the past year. Multi-level modeling results provided strong support for the stress generation process in children of affectively ill parents and highlight the importance of considering gender and age moderation effects.

Mental images: Specific or general,personal or impersonal?

In three experiments the relation between visual images classified in terms of the four categories of personal, impersonal, specific, and general images was explored. The results showed that subjects were able to generate all types of images, with personal images being the easiest to recall. Personal images, together with general images, were the image types being easiest to integrate with one another. Overall, the observations suggested the existence of two imagery dimensions: specific-general, and personal-impersonal. Memory was found to be best for personal images. Personal images turned out to be easier to integrate in memory than specific images. The findings were discussed in terms of different image generation models.     

Generating items during testing: Psychometric issues and models

On-line item generation is becoming increasingly feasible for many cognitive tests. Item generation seemingly conflicts with the well established principle of measuring persons from items with known psychometric properties. This paper examines psychometric principles and models required for measurement from on-line item generation. Three psychometric issues are elaborated for item generation. First, design principles to generate items are considered. A cognitive design system approach is elaborated and then illustrated with an application to a test of abstract reasoning. Second, psychometric models for calibrating generating principles, rather than specific items, are required. Existing item response theory (IRT) models are reviewed and a new IRT model that includes the impact on item discrimination, as well as difficulty, is developed. Third, the impact of item parameter uncertainty on person estimates is considered. Results from both fixed content and adaptive testing are presented.This article is based on the Presidential Address Susan E. Embretson gave on June 26, 1999 at the 1999 Annual Meeting of the Psychometric Society held at the University of Kansas in Lawrence, Kansas. —Editor     

Lexical retrieval constrained by sound structure: the role of the left inferior frontal gyrus

Positron emission tomography was used to investigate two competing hypotheses about the role of the left inferior frontal gyrus (IFG) in word generation. One proposes a domain-specific organization, with neural activation dependent on the type of information being processed, i.e., surface sound structure or semantic. The other proposes a process-specific organization, with activation dependent on processing demands, such as the amount of selection needed to decide between competing lexical alternatives. In a novel word retrieval task, word reconstruction (WR), subjects generated real words from heard non-words by the substitution of either a vowel or consonant. Both types of lexical retrieval, informed by sound structure alone, produced activation within anterior and posterior left IFG regions. Within these regions there was greater activity for consonant WR, which is more difficult and imposes greater processing demands. These results support a process-specific organization of the anterior left IFG.     

Neural correlates of comprehension and production of nouns and verbs in Chinese

This paper reports a conjunction analysis between semantic relatedness judgment and semantic associate generation of Chinese nouns and verbs with concrete or abstract meanings. The results revealed a verb-specific task-independent region in LpSTG&MTG, and task-dependent activation in a left frontal region in semantic judgment and the left SMG in semantic associate production. The observation of word class effects converged on Yu, Law, Han, Zhu, and Bi (2011), but contrasted with null findings in previous reports using a lexical decision task. While word class effects in the left posterior temporal cortices have been described in previous studies of languages with rich inflectional morphology, the significance of this study lies in its demonstration of the effects in these regions in a language known to have little inflectional morphology. In other words, differential neural responses to nouns and verbs can be observed without confounding from morphosyntactic operations or contrasts between actions and objects.
