How Many Mechanisms Are Needed to Analyze Speech? A Connectionist Simulation of Structural Rule Learning in Artificial Language Acquisition

Some empirical evidence in the artificial language acquisition literature has been taken to suggest that statistical learning mechanisms are insufficient for extracting structural information from an artificial language. According to the more than one mechanism (MOM) hypothesis, at least two mechanisms are required in order to acquire language from speech: (a) a statistical mechanism for speech segmentation; and (b) an additional rule-following mechanism in order to induce grammatical regularities. In this article, we present a set of neural network studies demonstrating that a single statistical mechanism can mimic the apparent discovery of structural regularities, beyond the segmentation of speech. We argue that our results undermine one argument for the MOM hypothesis.     

Rudolph Hermann Lotze's philosophically informed psychology

This essay deals with four main topics: the notion of philosophical psychology; the idea that physical events and mental events cannot be compared to one another; psychophysical mechanism; and the theory of local signs. These are all key elements in the Medicinische Psychologie of Rudolph Hermann Lotze (1817‒1881). By philosophical psychology, Lotze understands not only the collection of experimental data regarding physiological and mental states but also their philosophical processing outlining an interpretation of the real nature of the mind‒body connection. Within this framework, Lotze introduces the psychophysical mechanism as based on a key philosophical idea: mind and body are incomparable, but, nevertheless, they are in reciprocal relation (Wechselwirkung). In virtue of said special relation, movements that take place in the mental sphere of reality are transferred or translated in the bodily sphere and vice versa. This rearrangement (Umgestaltung) from one sphere of reality to the other is termed by Lotze “transformation to equivalent.” Through the concept of equivalence, Lotze supports the idea that the mind and the body form an organic whole. However, psychophysical mechanisms should not be seen as not a fixed series of physical changes followed by an equally fixed series of mental changes: physical changes are “read,” organized, and then transformed by the mind into something purely mental. This, in turn, produces new mechanical force and more physical changes. Lotze's legacy and long-term impact is finally read against the background of his contributions.     

Discrepancies Between Implicit and Explicit Self‐concepts of Intelligence Predict Performance on Tests of Intelligence

Three studies investigated the correspondence between implicit and explicit self‐concepts of intelligence and how that correspondence is related to performance on different intelligence tests. Configurations of these two self‐concepts were found to be consistently related to performance on intelligence tests in all three studies. For individuals who self‐reported high intelligence (high explicit self‐concept), a negative implicit self‐concept (measured with the Implicit Association Test) led to a decrease in performance on intelligence tests. For participants whose self‐report indicated a low self‐concept of intelligence, positive automatic associations between the self and intelligence had a similar effect. In line with a stress hypothesis, the results indicate that any discrepant configuration of self‐concepts will impair performance. Importantly, the prediction of performance on intelligence tests by the self‐concept of intelligence was shown to be independent of self‐esteem (Study 3).

婴儿语音感知发展及其机制

语音感知的发展状况对个体的语言发展有着深远影响。生命的第一年中, 在语言经验的作用下, 婴儿的语音感知从最初的普遍性感知逐渐发展为对母语的特异性感知。研究者们提出统计学习机制对这一过程加以解释, 即婴儿对语言环境中语音的频次分布十分敏感, 可以通过对频次分布的计算, 从语音的连续体中区分出在母语中起区别意义作用的各个语音范畴。同时, 功能性重组机制和一些社会性线索也会对婴儿语音感知的发展产生重要影响。

Minorities and the Philosophical Marketplace

This article argues for two theses. The first is that many of the sociological factors endemic in the philosophical community function as barriers to the recruitment of members of minority groups in the profession and to their functioning as public intellectuals. The division into familial groups, the fights for security and success, and the weakness of the federal organization of the American Philosophical Association all contribute to these barriers. The second is that sociology has a place in philosophy, even though it should not be confused with it. This means that philosophers need to consider social phenomena.     

敌意归因偏向对反应性攻击的预测及报复动机的中介作用

敌意归因偏向指将模糊情境中他人的行为意图进行敌意归因的倾向,其被认为是导致攻击的主要认知因素,但还缺乏其与反应性、主动性攻击的纵向关系的考察,而且其影响反应性攻击的动力机制也不清楚。本研究通过两个子研究来分别回应这两个问题。研究1的纵向调查结果显示,敌意归因偏向只纵向预测反应性攻击,而不能跨时间地预测主动性攻击。研究2对另一批大学生的横断面调查发现,报复动机可以中介敌意归因偏向与反应性攻击的关系。研究结果提示,敌意归因偏向很可能主要是在反应性攻击的形成中起到重要作用,而对主动性攻击的影响不大,报复动机则很可能是这种作用背后的动力机制之一。
