A stochastic growth model applied to repeated tests of academic knowledge

In the course of the medical program at the University of Limburg, students complete a total of 24 progress tests, consisting of items drawn from a constant itembank. A model is presented for the growth of knowledge reflected by these results. The Rasch model is used as a starting point, but both ability and difficulty parameters are taken to be random, and moreover the logistic distribution is replaced by the normal. Both individual and group abilities are estimated and explained through simple linear regression. Application to real data shows that the model fits very well.     

With a brick in hand. Transformation in exile

‘I’m like the man who took along a brick/to show the world what his house was like.’ Reflecting on Bertolt Brecht’s brick, which is symbolically taken along from the homeland, allows us the opportunity to explore the changing modalities of traumatic experience in displaced persons. The brick does not merely represent lost objects, home, and homeland but also stands for the displaced person and his psychic integrity. The challenge for every displaced person is to transition away from the basic survival mode, dominated by the drives of self-preservation, to regain the ability to symbolize and to start dreaming again. The way a poet processes his own traumatic experiences of displacement and escape may serve as a roadmap for others. Works by Mario Benedetti and Bertolt Brecht, both émigré poets, alongside clinical examples, form the psychological material. Recurring thoughts of an uncertain return to the homeland may become debilitating, causing a displaced person to descend into mourning or melancholy and can even lead to open outbursts of previously strongly defended aggression. If it is not possible to sufficiently work through the trauma, then the bricks will fall everywhere. In the regressive emotionally charged condition, it holds true: in the beginning was the act.     

德性自我意象、道德情绪与行为自我管理：对大学生的一项交叉滞后研究

研究采用交叉时序滞后设计,以问卷法对363名大学生进行了6个月的追踪调查,考察了德性自我意象、道德情绪（内疚/羞愧）与行为自我管理之间的相互预测关系。结果表明,德性自我意象、内疚和羞愧均能显著地正向预测道德行为自我管理,德性自我意象、内疚和羞愧可能是道德行为自我管理的前因变量。     

Prioritizing—The task strategy of the powerful?

Previous research has shown that power increases focus on the main goal when distractor information is present. As a result, high-power people have been described as goal-focused. In real life, one typically wants to pursue multiple goals at the same time. There is a lack of research on how power affects how people deal with situations in which multiple important goals are present. To address this question, 158 participants were primed with high or low power or assigned to a control condition, and were asked to perform a dual-goal task with three difficulty levels. We hypothesized and found that high-power primed people prioritize when confronted with a multiple-goal situation. More specifically, when task demands were relatively low, power had no effect; participants generally pursued multiple goals in parallel. However, when task demands were high, the participants in the high-power condition focused on a single goal whereas participants in the low-power condition continued using a dual-task strategy. This study extends existing power theories and research in the domain of goal pursuit.     

Predicting stress patterns in an unpredictable stress language: The use of non-lexical sources of evidence for stress assignment in Russian

The main goal of this research was to examine how readers of Russian assign stress to disyllabic words. In particular, we tested the claim that the process of stress assignment in Russian can only be accomplished lexically. Eleven potential non-lexical sources of evidence for stress in Russian were examined in regression and factorial studies. In Study 1, onset complexity, coda complexity, the orthography of the first syllable (CVC1), of the second syllable (CVC2), and of the ending of the second syllable (VC2) were found to be probabilistically associated with stress in Russian disyllables. In Studies 2 and 3, it was shown that Russian speakers do use 3 of these cues (CVC1, CVC2, and VC2) when making stress-assignment decisions. These results provide evidence against the idea that the nature of stress in the Russian language is so unpredictable that stress assignment can only be accomplished lexically. These results also suggest that any successful model of stress assignment in Russian needs to contain mechanisms allowing these 3 orthographic cues to play a role in the stress-assignment process.     

Oneness Experience: Looking Through Multiple Lenses

This article defines healthy oneness experience and establishes the progressive, life enhancing components of the experience. The author clarifies the paradox that a cohesive, well-integrated self allows unitive, non-self-definitional experiences. The author attempts to work the cultural/clinical border by exploring oneness phenomena as they occur in art, religion, literature and the clinical consulting room. The author uses psychoanalytic tools to understand non-clinical experiences of oneness. Through compelling accounts of such experiences as described by artists, writers and meditators, psychoanalytic theorizing about oneness is illumined further.     

Simultaneous classification and multidimensional scaling with external information

For the exploratory analysis of a matrix of proximities or (dis)similarities between objects, one often uses cluster analysis (CA) or multidimensional scaling (MDS). Solutions resulting from such analyses are sometimes interpreted using external information on the objects. Usually the procedures of CA, MDS and using external information are carried out independently and sequentially, although combinations of two of the three procedures (CA and MDS, or multidimensional scaling and using external information) have been proposed in the literature. The present paper offers a procedure that combines all three procedures in one analysis, using a model that describes a partition of objects with cluster centroids represented in a low-dimensional space, which in turn is related to the information in the external variables. A simulation study is carried out to demonstrate that the method works satisfactorily for data with a known underlying structure. Also, to illustrate the method, it is applied to two empirical data sets.     

The role of stimulus ambiguity and movement in spatial navigation: a multiple memory systems analysis of location discrimination

This paper reviews recent findings about how rats navigate by learning to discriminate among locations. The assumption underlying the experiments and their interpretation is that the information required to do this is learned by three independent, parallel memory systems. One system processes cognitive information (or "knowledge"), a second system processes reinforced stimulus-response associations and a third processes Pavlovian conditioned responses in the form of stimulus-affect associations. The information stored in each system produces behavior that, in some cases, results in a location discrimination. The present experiments focus on three factors that influence what each system learns and whether the resulting memory produces behavior that results in a location discrimination. One factor is whether the locations to be discriminated can be identified by unique, unambiguous stimuli or whether they are ambiguously associated with the same stimuli. The second factor is whether the stimuli are observed passively or whether the rats move among them, voluntarily or involuntarily. The third factor is whether or not the rats perform specific reinforced responses in the presence of the stimuli. Instances of co-operative behavioral outputs from memory systems that facilitate location discriminations and of competitive outputs that impede discriminations are described.     

Winnicott, Balint, and the Independent Tradition

This article compares and contrasts two main aspects of the work of Winnicott and Balint: their theories of infantile development and their theoretical and clinical work on the use of regression as a therapeutic agent. The relationship of their thinking to aspects of the British Independent Group's theories and clinical work is noted vis-à-vis the basic acceptance of classical theory and technique, acknowledgment and use of some of Klein's contributions, the influence of trauma and the external environment on psychic development and psychopathology, the importance of holding and the setting, and the reintegration of previously split off and lost parts of the self.     

Breaking the Solid Ground of Common Sense: Undoing “Structure” with Michael Balint

Balint's great merit was to question what, in the classical perspective, was assumed as a prerequisite for analysis and thus located beyond analysis: the maturity of the ego. A fundamental premise of his work was Ferenczi's distrust for the structural model, which praised the maturity of the ego and its verbal, social, and adaptive abilities. Ferenczi's view of ego maturation as a trauma derivative was strikingly different from the theories of all other psychoanalytic schools and seems to be responsible for Balint's understanding of regression as a sort of inverted process that enables the undoing of the sheltering structures of the mature mind. Balint's understanding of the relation between mature ego and regression diverged not only from the ego psychologists, who emphasized the idea of therapeutic alliance, but also from most of the authors who embraced the object-relational view, like Klein (who considered regression a manifestation of the patient's craving for oral gratification), Fairbairn (who gave up the notion of regression), and Guntrip (who viewed regression as a schizoid phenomenon related to the ego weakness). According to Balint, the clinical appearance of a regression would depend also on the way the regression is recognized, is accepted, and is responded to by the analyst. In this respect, his position was close to Winnicott's reformulation of the therapeutic action. Yet, the work of Balint reflects the persuasion that the progressive fluidification of the solid structure could be enabled only by the analyst's capacity for becoming himself or herself [unsolid].
