论数学问题解决中情境模型与问题模型的关系

情境模型与问题模型是数学问题解决研究中的两个重要概念,前者是对问题所述情境的日常化的定性表征,后者是基于图式知识对问题关键变量的数量关系表征。本文介绍了两种模型的发展历史以及目前存在的争议,并提出了未来研究需要解决的问题。     

竞争情境中的人格取向——理论建构及实证

尝试用新的视角——取向研究视角,对竞争情境中的人格进行整合研究,建构一种与社会情境结合更紧密,更具概括性的人格取向理论。人格取向理论的假设建构模型包括四种人格取向维度：社会取向,个人取向,积极取向和消极取向。根据理论模型编制竞争情境人格取向量表,以1399名被试为研究对象,运用探索性因素分析和验证性因素分析方法对该理论模型进行实证研究。结果证明了该理论建构的存在,理论建构中各维度的因素负荷和拟合指数良好,竞争情境人格取向量表具有良好的信度和建构效度,既可作为证明该理论建构的有效工具,亦可作为评估竞争情境人     

Personality,Punishment and Public Goods: Strategic Shifts Towards Cooperation as a Matter of Dispositional Honesty–Humility

Contributions in the public goods game—a classical social dilemma situation—have been shown to depend strongly on the presence versus absence of punishment or sanctions for free riders. Also, there appear to be noteworthy individual differences in the degree to which decision makers cooperate. Herein, we aimed to bring these two lines of research together. Firstly, we predicted that both presence of punishment and high dispositional Honesty–Humility (as conceptualized in the Honesty–Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness to experience model of personality) should yield higher contributions. Secondly, and more importantly, we expected an interaction, such that only those low in Honesty–Humility would condition their behaviour on the presence versus absence of punishment, thus employing cooperation strategically. In line with the hypothesis, the results of two experiments (one of which comprised a longitudinal design) corroborated that the degree to which decision makers shift towards higher contributions when punishment is introduced depends on their dispositional level of Honesty–Humility.

Causes of boredom: The person,the situation,or both?

Some theories emphasize the role of the situation, some emphasize the role of the person, and some emphasize the interaction between situation and person in causing boredom. The present study examines these models by determining whether boredom propensity (person) and/or experimental condition (situation) independently or in interaction affected state boredom. The study also examined the relative contribution of behavioural activation and inhibition to state boredom. Boredom propensity and condition significantly and independently predicted state boredom, as did the interaction between behavioural inhibition and condition. Implications are discussed, including the possibility of two distinct causes of boredom.     

Statistical modelling in the investigation of stranger rape

A sample of stranger rape offences (n = 271) registered in the Dutch Violence Crime Linkage Analysis System database in the Netherlands between 1997 and 2007 was studied with the objective of developing statistical models, which give an indication of the probability of basic offender characteristics. Observable crime characteristics concerning the modus operandi, interaction between the offender and the victim, violence, precautionary measures, and sexual behaviours were selected in the dataset. Offender characteristics were selected based on their usefulness for the police organisation in narrowing the scope of a criminal investigation. Spatial behaviour, criminal history, and living situation of the offender were selected. From the predictive models, four out of five achieved a correct rate of over 70%, and all models predicted better than the best guess method. The proposed models for distance and prior convictions for violence seem particularly promising. Both these models show an improvement of correctly predicted offender characteristics of more than 20 percentile points compared with that which could have been estimated based on the average in the total sample. The predictive value of the models needs to be tested further with ‘new offences’, which were not used to construct the model. In general, the current study supports the finding that crime characteristics can be used to get an indication of the probability of certain offender characteristics. Nevertheless, for an understanding of the relationship between the crime characteristics and offender characteristics, a further development of a theoretical framework is urgently necessary.

Parents' work burnout and adolescents' school burnout: Are they shared?

There is considerable evidence that psychological distress not only has consequences for those who experience it but also can create problems for other members of the distressed person's family. To examine whether parents' work burnout and their children's school burnout are shared in the family, 515 adolescents (median age = 15) completed scales for school burnout and 595 of their parents (342 mothers, 253 fathers) completed scales for work burnout and their economic situation. The intraclass correlations showed that parents' work burnout and adolescents' school burnout was shared in the family. In addition, the better the economic situation the parents' experienced, the lower was the level of shared burnout in the family.     

On the impact of words: interpretation,empathy and affect regulation

This paper offers a contribution towards furthering our understanding of a theme more usually associated with the Freudian tradition, namely the role and function of words as action, particularly in relation to the representational process and its somatic roots. Some reference to neuroscience research will be offered in this respect. It also considers the value of differentiating Empathy from Empathism, as defined by the Italian psychoanalyst Stefano Bolognini who distinguishes informing complementary countertransference from states of over‐concordance. Two analytic sessions taken from the intensive analysis of a deeply deprived late‐latency child showing violent behaviour are provided with the aim of illustrating the application of these concepts. It is argued that, given the same elaboration of the countertransference and the adequate empathic position on the part of the analyst, the difference in the outcome of the interpretation was made by the specific use of words—in this case the use or not of the personal pronoun―in the two sessions. As the case material is taken from the clinical work of a supervisee, some elements regarding the supervisory situation are also discussed in the paper.     

Emergentism and supervenience physicalism

I argue that it is intuitive and useful to think about composition in the light of the familiar functionalist distinction between role and occupant. This involves factoring the standard notion of parthood into two related notions: being a parthood slot and occupying a parthood slot. One thing is part of another just in case it fills one of that thing's parthood slots. This move opens room to rethink mereology in various ways, and, in particular, to see the mereological structure of a composite as potentially outreaching the individual entities that are its parts. I sketch one formal system that allows things to have individual entities as parts multiple times over. This is particularly useful to David Armstrong, given Lewis's charge that his structural universals must do exactly that. I close by reflecting upon the nature and point of formal mereology.     

Measuring Situation Awareness in Virtual Environment-Based Training

We evaluated the efficacy of a computer-based situation awareness (SA) measurement system for training dismounted infantry SA in an urban terrain virtual reality (VR) simulation. Based on past research, we hypothesized that the SA measures would be sensitive to individual (squad leader) differences, and that the frequency of specific probes would reveal differences in critical SA requirements among scenarios. Three infantry squads performed multiple trials across two different scenarios. A confederate platoon leader posed probes to squad leaders during trials and experts made ratings afterward. Results revealed squad leaders had similar responses to probes, despite differences in combat experience. Analysis of probe frequency revealed different high priority SA elements and decisions for each scenario. The SA behavior and communication ratings revealed differences among squads, which trended with experience. Measures of SA were also consistent across the test scenario as a result of similar mission types and task difficulties. We discuss the implication of our findings for future research and theory within this area.
