Developmental changes in infants' sensitivity to octave-band noises

Localization responses to octave-band noises with center frequencies at 200, 400, 1000, 2000, 4000, and 10,000 Hz were obtained from infants 6, 12, and 18 months of age. During an experimental trial, an octave-band noise was presented on one of two speakers located 45° to each side of the infant. A head turn to the noise (correct response) was rewarded by activating an animated toy on top of the speaker. The intensity of the noise was varied over trials (method of constant stimuli) to determine thresholds at each center frequency. Thresholds for the lower frequencies were approximately 5–8 db higher in the 6-month-old infants compared to the older infants. However, there were no consistent differences among groups at the higher frequencies. Infant thresholds were found to be 20–30 db higher than adult thresholds at the lower frequencies. At the higher frequencies thresholds for infants were approaching those of adults.     

Why Mikey's right and my key's wrong: The significance of stress and word boundaries in a child's output system

The systematic errors children make in the course of phonological development, like adult production errors and adult phonological processes, can provide evidence of language production mechanisms. A detailed investigation of the environments in which velar stops are fronted by a phonologically delayed child reveals that fronting is dependent on both word stress and word boundaries; that it shows lexical exceptions; and that it occurs in output only. This distribution suggests that the child has output lexical representations which are independent of input lexical representations, and that the fronting error occurs in these output representations. It also suggests that prosodic features are crucial to the identification of articulatory features within these representations. Such an analysis has implications for theories of lexical access, and for the development of lexical access in children.     

Advance Directives Outside the USA: Are They the Best Solution Everywhere?

This article evaluates the potential role of advance directives outside of their original North American context. In order to do this, the article first analyses the historical process which has promoted advance directives in recent years. Next, it brings to light certain presuppositions which have given them force: atomistic individualism, contractualism, consumerism and entrepreneurialism, pluralism, proceduralism, and American moralism. The article next studies certain European cultural peculiarities which could affect advance directives: the importance of virtue versus rights, stoicism versus consumerist utilitarianism, rationalism versus empiricism, statism versus citizens' initiative, and justice versus autonomy.The article concludes by recognising that autonomy has a transcultural value, although it must be balanced with other principles. Advance Directives can have a function in certain cases. But it does not seem adequate to delegate to advance directives more and more medical decisions, and to make them more binding everyday. It is indispensable to develop other decision-making criteria.     

Syntactic structure and artificial grammar learning: the learnability of embedded hierarchical structures

Embedded hierarchical structures, such as "the rat the cat ate was brown", constitute a core generative property of a natural language theory. Several recent studies have reported learning of hierarchical embeddings in artificial grammar learning (AGL) tasks, and described the functional specificity of Broca's area for processing such structures. In two experiments, we investigated whether alternative strategies can explain the learning success in these studies. We trained participants on hierarchical sequences, and found no evidence for the learning of hierarchical embeddings in test situations identical to those from other studies in the literature. Instead, participants appeared to solve the task by exploiting surface distinctions between legal and illegal sequences, and applying strategies such as counting or repetition detection. We suggest alternative interpretations for the observed activation of Broca's area, in terms of the application of calculation rules or of a differential role of working memory. We claim that the learnability of hierarchical embeddings in AGL tasks remains to be demonstrated.     

The importance of values in predicting Turkish youth's opinions about the European Union in light of the Copenhagen Political Criteria

The enlargement process of the European Union may be regarded as one of the most important social projects of human history in that it is trying to unite several nation-states under a "European identity." As a historically and culturally "distant" candidate, Turkey has been asked to meet a set of expectations referred to as the "Copenhagen Criteria," requiring a series of large-scale reforms to the infrastructure and superstructure of the country. Taking advantage of the unique opportunity to relate Turkish people's opinions on the criteria to their values, hypotheses based on Schwartz's model of values were tested. Schwartz's Personal Values Questionnaire and a questionnaire measuring opinions on the criteria and the Union were completed by 368 Turkish university students. Factor analysis of the opinion items yielded five factors: reduction of military influence in civil life, scepticism towards Europe and the European Union, improvement of human rights and liberties, improvement of minority rights, and lack of transparency in public institutions. Regression analyses showed that values and nationalism were powerful predictors of opinions whereas the effect of religiosity was limited only to the prediction of a preference for the reduction of military influence in civil life. Preference for openness to change values were successful in predicting variance in three of the five criteria: The more the participants favoured these values, the more they supported the improvement of human rights and liberties, the improvement of minority rights, and regretted the lack of transparency. Self-transcendence values were also positively related to support for the same three criteria together with a preference for reduction of military influence. As for nationalism, the results showed that this variable was related negatively to reduction of the military influence, improvement of human rights and liberties, improvement of minority rights; and positively to scepticism.     

Développement de la mémoire de travail : relations du centre exécutif avec la boucle phonologique et le calepin visuospatial chez des enfants de CE1 et de CM2

The aim of this study was to examine the development of working memory's components and their relationships. Phonological loop's, visuospatial sketchpad's and central executive's efficiencies were assessed by simple and complex span tasks and executive tasks with verbal and visuospatial material. The analyses were performed on 64 second-grade and 55 fifth-grade children's data. Developmental performances improvement was examined according to tasks and material. Analyses of variance revealed performances improvement according to age and type of material (verbal > non verbal) for the slave system tasks and for a part of central executive's tasks. Correlation analysis and exploratory factorial analysis suggested that slave systems would become progressively more specific and that central executive's efficiency would be dependent on this specialization.     

Equality of Education and Citizenship: Challenges of European Integration

What kind of equality among Europeans does equal citizenship require, especially regarding education? In particular, is there good reason to insist of equality of education among Europeans—and if so, equality of what? To what extent should the same knowledge base and citizenship norms be taught across state borders and religious and other normative divides? At least three philosophical issues merit attention: (a) The requirements of multiple democratic citizenships beyond the nation state; (b) how to respect diversity while securing such equality and inculcating commitments to justice and norms of citizenship, and (c) The multiple reasons for equality of various kinds among political equals living in a Union as compared to a unitary state. The article responds on the basis of several arguments in favour of certain kinds of equality. All Union citizens must enjoy a high minimum level of education, and all pupils must be informed concerning the various ways of life prevalent in Europe. Furthermore, there must be standards for securing equality of opportunity across the EU, though it is difficult to measure under multiculturalism. Citizens must also be socialised to certain ‘citizenship norms’. This shared basis to be taught in schools should avoid contested religious or philosophical premises as far as possible. Yet the school system should socialise pupils to three commitments: to the just domestic and European institutions and hence the legislation they engender, to principles that justify these institutions; and to a political theory that grounds these principles in a conception of the proper role of individuals, of member states and of the Union. I also argue that equality of result is not a plausible normative requirement among Europeans, while equality of opportunity is. The paper concludes with some comments on the lessons to be drawn for ‘Global’ citizenship.     

Changing patterns of religious affiliation,church attendance and marriage across five areas of Europe since the early 1980s: trends and associations

This study draws on three waves of the European Values Survey (conducted between 1981 and 1984, between 1989 and 1993, and between 1999 and 2004) across five countries for which full data are available (Great Britain, Italy, the Netherlands, Northern Ireland, Spain, and Sweden) in order to address five research questions. Question one examined changes in religious affiliation. Across all five countries, the proportions of the non‐affiliated increased. Question two examined changes in church attendance. Across all five countries, the proportions of the non‐attenders increased. Question three examined changes in marital status. Across all five countries the proportions of the population checking the category ‘married’ declined, although in Spain the decline was marginal. Question four examined the association between religious affiliation and being married. The religious affiliated were more likely to be married than the non‐affiliated. Question five examined the association between church attendance and being married. Weekly attenders were more likely to be married than the non‐attenders. Overall these data support the close association between religion and marriage across five European countries (where there are very different religious climates) and support the hypothesis that changing religious values and changing family values go hand‐in‐hand.
