Better than average? When can we say that subsampling of items is better than statistical summary representations?

Myczek and Simons (2008) have described a computational model that subsamples a few items from a set with high accuracy, showing that this approach can do as well as, or better than, a model that captures statistical representations of the set. Although this is an intriguing existence proof, some caution should be taken before we consider their approach as a model for human behavior. In particular, I propose that such simulation-based research should be based on a more expanded range of phenomena and that it should include more accurate representations of errors in judgments.     

初中生自我调节学习的类型及对学习的影响

自我调节学习是一种学习者主动激励自己并积极使用适当的学习策略的学习,研究利用潜在剖面分析法和辨别分析法对316名初中生自我调节学习的类型进行考察,探讨不同自我调节学习类型初中生的特点,分析自我调节学习类型对学习动机、焦虑、学习成绩的影响。结果表明:(1)初中生自我调节学习分成综合发展型、均衡调节型和策略滞后型3种。(2)综合发展型初中生的自我调节学习水平最高,策略滞后型初中生的自我调节学习水平尤其是学习策略水平最低,而均衡调节型初中生的自我调节学习水平处于综合发展型和策略滞后型之间。(3)自我调节学习类型对学习动机、焦虑、学习成绩有影响。     

Contra Cartwright: Structural Realism, Ontological Pluralism and Fundamentalism About Laws

In this paper I argue against Nancy Cartwright’s claim that we ought to abandon what she calls “fundamentalism” about the laws of nature and adopt instead her “dappled world” hypothesis. According to Cartwright we ought to abandon the notion that fundamental laws (even potentially) apply universally, instead we should consider the law-like statements of science to apply in highly qualified ways within narrow, non-overlapping and ontologically diverse domains, including the laws of fundamental physics. For Cartwright, “laws” are just locally applicable refinements of a more open-ended concept of capacities. By providing a critique of the dappled world approach’s central notion of open ended capacities and substituting this concept with an account of properties drawn from recent writing on the subject of structural realism I show that a form of fundamentalism is viable. I proceed from this conclusion to show that this form of fundamentalism provides a superior reading of case studies, such as the effective field theory program (EFT) in quantum field theory, than the “dappled world” view. The case study of the EFT program demonstrates that ontological variability between theoretical domains can be accounted for without altogether abandoning fundamentalism or adopting Cartwright’s more implausible theses.     

Path dependent preferences: The role of early experience and biased search in preference development

What is the role of early experiences in shaping preferences? What are the mechanisms by which such early encounters influence the way preferences are formed? In this research, we examine the impact of the entry position and favorability of initial (and ongoing) experiences on preference development. We predict that the starting point will heavily influence which particular region people select from initially, and favorableness of early experiences and myopic search will both limit their search to that particular region. Across four studies, we find that when the initial experiences are favorable, subjects engage in lower levels of search, experience only a narrow breadth of possible alternatives, demonstrate less ongoing experimentation, and have a reduction in the amount of preference development.

Garner interference and temporal information processing

The aim of the study was to explore whether temporal information processing can interfere with performance of a non-temporal task. A new methodology based on the Garner paradigm was employed. Participants were asked to classify two-dimensional stimuli according to either length or duration, with and without variation in the other (task-irrelevant) dimension. Garner interference was detected only with respect to classification by length when irrelevant variation in duration was present. Stroop interference was detected only in classification by length across compatible and non-compatible values of length and duration. Classification by length took more time when done with variation in duration than when duration was constant. Classification by length also took more time when length and duration were not compatible than when they were compatible. The findings indicate that the processing of duration is similar to the processing of other perceptual dimensions. The processing of duration consumes attentional resources and can interfere with the processing of other perceptual dimensions. The findings support attentional models of prospective duration judgment.     

Family Therapy, You Make Me Feel Like Dancing

In this article we use our experience with ballroom dancing to revisit three central systemic/relational ideas—summativity, pragmatics/aesthetics, and communication—in order to reaffirm our theoretical grounding in family therapy and to connect that grounding to community-mindedness in therapy. Community-mindedness consists of deliberate attention to the socially constructed grand narratives that dominate clients and therapists in the process of therapy. A detailed example is provided.

Studienbezogene Belastungen, Lebensqualität und Beziehungserleben bei Medizinstudenten

In a cross-sectional study of medical students we examined educational strains, health feeling, and relationship patterns. Work stress was measured using the questionnaire by Jurkat et al., health-related quality of life was measured using the Short Form- (SF-)36 Health Survey, and relationship patterns to the partner as well as to a friend were mapped using“Beziehungsmusterfragebogen“ (BeMus). Study stress was assessed as being high by 60% of the students. Consequently, 39% had not enough time for their partners und 29% had no time for own interests. The mental health averaged significantly below the norm. A high workload and discontent correlated with aggressiveness, especially in the partnership, whereas loving care towards the partner or friend correlated with a high level of satisfaction and a lower strain level. Therefore, an improvement of psychosocial competence in medical students as well as a practice-oriented preparation for the profession is needed.
