During the first year of life, infants begin to have difficulties perceiving non‐native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non‐segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a language with fixed stress) have great difficulties in perceiving stress contrasts ( Dupoux, Pallier, Sebastián & Mehler, 1997 ), whereas speakers of Spanish (a language with lexically contrastive stress) perceive these contrasts as accurately as segmental contrasts. We show that language‐specific differences in the perception of stress likewise arise during the first year of life. Specifically, 9‐month‐old Spanish infants successfully distinguish between stress‐initial and stress‐final pseudo‐words, while French infants of this age show no sign of discrimination. In a second experiment using multiple tokens of a single pseudo‐word, French infants of the same age successfully discriminate between the two stress patterns, showing that they are able to perceive the acoustic correlates of stress. Their failure to discriminate stress patterns in the first experiment thus reflects an inability to process stress at an abstract, phonological level. 相似文献

The aims of this study are to consider the experience of flow from a nonlinear dynamics perspective. The processes and temporal
nature of intrinsic motivation and flow, would suggest that flow experiences fluctuate over time in a dynamical fashion. Thus
it can be argued that the potential for chaos is strong. The sample was composed of 20 employees (both full and part time)
recruited from a number of different organizations and work backgrounds. The Experience Sampling Method (ESM) was used for
data collection. Once obtained the temporal series, they were subjected to various analyses proper to the complexity theory
(Visual Recurrence Analysis and Surrogate Data Analysis). Results showed that in 80% of the cases, flow presented a chaotic
dynamic, in that, flow experiences delineated a complex dynamic whose patterns of change were not easy to predict. Implications
of the study, its limitations and future research are discussed. 相似文献

The appropriate selection of both pictorial and linguistic experimental stimuli requires a previous languagespecific standardization
process of the materials across different variables. Considering that such normative data have not yet been collected for
Modern Greek, in this study normative data for the color version of the Snodgrass and Vanderwart picture set (Rossion & Pourtois,
2004) were collected from 330 native Greek adults. Participants named the pictures (providing name agreement ratings) and
rated them for visual complexity and age of acquisition. The obtained measures represent a useful tool for further research
on Greek language processing and constitute the first picture normative study for this language. The picture norms from this
study and previous ones may be downloaded from brm.psychonomic-journals.org/content/supplemental. 相似文献

Multiple-baseline designs are an extension of the basic single-case AB phase designs, in which several of those AB designs
are implemented simultaneously to different persons, behaviors, or settings, and the intervention is introduced in a staggered
way to the different units. These designs are well-suited for research in the behavioral sciences. We discuss the advantages
and limitations for valid inferences, and suggest a statistical technique—randomization tests—for use with multiple-baseline
data, to complement visual analysis. In addition, we provide an extension of our SCRT-R package (which already contained means
for conducting randomization tests on single-case phase and alternation designs), for multiple-baseline AB data. 相似文献

In this paper, I defend a representationalist account of the phenomenal character of color experiences. Representationalism, the thesis that phenomenal character supervenes on a certain kind of representational content, so-called phenomenal content, has been developed primarily in two different ways, as Russellian and Fregean representationalism. While the proponents of Russellian and Fregean representationalism differ with respect to what they take the contents of color experiences to be, they typically agree that colors are exhaustively characterized by the three dimensions of the color solid: hue, saturation, and lightness. I argue that a viable version of representationalism needs to renounce this restriction to three dimensions and consider illumination to be a genuine phenomenal dimension of color. My argument for this thesis falls into two parts. I first consider the phenomenon of color constancy in order to show that neither Russellian nor Fregean representationalism can do justice to the phenomenal significance of local illumination. I subsequently formulate a version of representationalism that accounts for illumination by taking it as a phenomenal dimension of color. 相似文献

This article compiles the investigations carried out by a Research Group of the University of Granada, Spain. Its different
projects on writing’s cognitive social and cultural processes have been supported by the Spanish Government. This line of
research joined together linguistic, psychological, social and cultural contributions to the development of writing from the
1970s. Currently, this line of research develops in collaboration with other European Universities: (a) Interuniversity Centre
for Research On Cognitive Processing in Natural and Artificial Systems (ECONA), “La Sapienza” University of Rome (Italy);
(b) Anadolu University, (Eskisehir, Turkey); (c) Coimbra University (Portugal); (d) University of Zaragoza (Spain); (e) the
Institute of Education of the University of London (United Kingdom). The aforementioned collaboration is materializing into
projects like the International Master on Multilingual Writing: Cognitive, Intercultural and Technological Processes of Written
Communication () and the International Congress: Writing in the twenty-first Century: Cognition, Multilinguisim and Technologies, held in
Granada (). This research line is focussed on the development of strategies in writing development, basic to train twenty-first century
societies’ citizens. In these societies, participation in production media, social exchange and the development of multilingual
written communication skills through new computer technologies spread multicultural values. In order to fulfil the social
exigencies, it is needed to have the collaboration of research groups for designing and applying international research projects.

The article discusses the field of Forensic Psychology in Czech Republic. It concentrates upon the successes and stagnations of the field, which can be attributed to the political and historical development of the country. After a brief historical background and demographic information, the article introduces the history and structure of the police force and prison service. The article then moves on to discuss the history and publication development of the field of Forensic Psychology and its use in practice. It characterizes the field from its beginnings between the two wars, to the activities of the Research Institute of Penology from 1967 to1980 and the years following the political change of 1989. The article concludes with the law framework within which the field operates. Based upon this summary of the situation in Czech republic, the author makes an assessment of the status of Forensic Psychology in Czech republic, especially in terms of conducting research for the practice.

Systems biology is the rapidly growing and heavily funded successor science to genomics. Its mission is to integrate extensive bodies of molecular data into a detailed mathematical understanding of all life processes, with an ultimate view to their prediction and control. Despite its high profile and widespread practice, there has so far been almost no bioethical attention paid to systems biology and its potential social consequences. We outline some of systems biology's most important socioethical issues by contrasting the concept of systems as dynamic processes against the common static interpretation of genomes. New issues arise around systems biology's capacities for in silico testing, changing cultural understandings of life, synthetic biology, and commercialization. We advocate an interdisciplinary and interactive approach that integrates social and philosophical analysis and engages closely with the science. Overall, we argue that systems biology socioethics could stimulate new ways of thinking about socioethical studies of life sciences. 相似文献
