Psychology and the fall of Communism: The special case of (East) Germany

The fall of Communism is now universally agreed to be what the philosopher Hegel called a world historical event—one that few predicted but nearly everyone saw as inevitable after it happened. In the aftermath many lives—and worldviews—changed, not only, but also in the human sciences. These remarks attempt to address in a preliminary way both the impact of the fall of Communism on psychology in former East Germany (including changes in personnel and approach) and the ways in which these sciences were employed as resources for reflection on the Communist past as well as the transition to new social and political regimes.     

Infinite Set Unification with Application to Categorial Grammar

In this paper the notion of unifier is extended to the infinite set case. The proof of existence of the most general unifier of any infinite, unifiable set of types (terms) is presented. Learning procedure, based on infinite set unification, is described.     

Strategies in relational inference

Three experiments are reported in which the relationships between task format, item type, and strategy usage were investigated for a two-dimensional relational inference task. Contrary to past findings with linear syllogisms, it was found that parallel presentation (presenting problem statements simultaneously) did not result in any increased use of deduction rule processes compared with serial presentation (presenting problem statements individually). Instead, the results suggested that mental models were used by the majority of subjects, and that multiple models were more likely to be constructed with parallel presentation. It is proposed that, in general, multiple model construction will be more frequent for deduction tasks where the cognitive load is relatively low. Hence, contrary to suggestions by Polk and Newell (1995), reasoning in this way appears to be prevalent and highly robust—where supported by task format—even where the use of this strategy is disadvantageous.     

Anforderungen an eine physikalische Fundamentaltheorie

Requirements for a Fundamental Physical Theory. The search for a so-called ‘Theory of Everything’ which should lead to the unification of all fundamental forces is seen, at present, as a matter of priority within theoretical high-energy physics. Some physicist identify this Theory of Everything today with aspecific type of superstring theory or its intended conceptual continuation, called M-Theory. The objective of this article is the discussion of the requirements a fundamental physical theory has to comply with. This question can only be clarified if one takes into account that the claim that a physical theory is all-encompassing takes forgranted some tacit prerequisites which concern the conceptual and epistemological foundations of science and, not least, the question for the realizability of its reductionistic unity. This revised version was published online in August 2006 with corrections to the Cover Date.     

Liberal–conservative dimension of moral concerns underlying political faction formation in Taiwan

Moral foundations theory provides a framework for understanding the traditional liberal–conservative dichotomy in political factions. Typically, factions on the liberal side are more concerned with individualizing foundations—including care/harm and fairness/cheating—for the protection of individual rights and welfare whereas factions on the conservative side are concerned with both individualizing and binding foundations—including loyalty/betrayal, authority/subversion, and sanctity/degradation—for the maintenance of existing social ethics. Our research extended this framework to the analysis of Taiwanese political factions, which are not distributed conspicuously along the liberal–conservative line but instead on whether Taiwan should become a legally independent state or unify with the People's Republic of China (Mainland China). Our results indicate that despite the scarce use of the terms liberal or left and conservative or right in common communication, a liberal–conservative dimension underlies the Taiwanese political spectrum. Specifically, supporters of Taiwan independence exhibit liberal‐like moral concerns whereas supporters of China unification and the status quo demonstrate conservative‐like moral concerns. Moreover, indirect effects exist through moral foundations from political factions to stances on social issues; this is especially prevalent in the case of Taiwan independence camp's clear support for the legalization of same‐sex marriage, a stance resulting from anti‐authoritarian moral and political characteristics.     

The Impact of Family Unification Housing Vouchers on Child Welfare Outcomes

This study addresses whether providing housing vouchers through the Family Unification Program (FUP) to families involved in the child welfare system reduces child maltreatment and the need for child welfare services. The study uses child welfare administrative data on 326 children in Portland, Oregon, and 502 children in San Diego, California from the point at which their families were referred to the program through 18 months post‐referral. Using a quasi‐experimental waitlist comparison design, probit regressions show little impact of FUP on preventing child removal from home, but some positive impact on reunification among children already placed out of home. Hazard estimations show receipt of FUP speeds up child welfare case closure. Impacts on new reports of abuse and neglect are mixed, but point toward reduced reports. Low rates of removal among intact comparison families and high rates of reunification for children in out‐of‐home care suggest poor targeting of housing resources. Housing vouchers are being given to families not bearing the risks the program is intended to address. The presence of some positive findings suggests that housing vouchers might help reduce child welfare involvement if better targeting were practiced by child welfare agencies.     

On the Theoretical Unification and Nature of Fallacies

I argue in a non-reductive sense for a plausible epistemic principle, which can (1) theoretically and instrumentally unify or systematize all fallacies, and (2) provide a justification for using such a principle for characterizing an erroneous argument as a fallacy. This plausible epistemic principle involves the idea of an error in the method of justification, which results in a failure to provide relevant evidence to satisfy certain standards of adequate proof. Thus, all fallacies are systematically disguised failures to provide substantive proof: a failure in the attempt to persuade rationally, as opposed to emotionally or rhetorically. I argue that the epistemic idea of begging the question is essential to this idea of a fallacy as an inadequate proof.     

语篇理解中语义整合的神经机制及其影响因素

语义整合是把当前阅读中新出现的词语与之前的语境进行语义联结以形成连贯表征的过程。在语篇理解中, 很多理论都确定了整合这一过程的重要性, 语义整合是达成语篇连贯的一个关键步骤, 探究其神经机制及影响因素对理解语篇有重要意义。已有的ERP研究表明语篇理解中的语义整合是即时发生的; 已有的fMRI研究和神经震荡的分析提供了参与这一过程的具体脑区和神经网络的证据。其影响因素主要包括语篇内因素、非言语因素和个体差异。
