Although researchers studying human speech recognition (HSR) and automatic speech recognition (ASR) share a common interest in how information processing systems (human or machine) recognize spoken language, there is little communication between the two disciplines. We suggest that this lack of communication follows largely from the fact that research in these related fields has focused on the mechanics of how speech can be recognized. In Marr's (1982) terms, emphasis has been on the algorithmic and implementational levels rather than on the (...) computational level. In this article, we provide a computational-level analysis of the task of speech recognition, which reveals the close parallels between research concerned with HSR and ASR. We illustrate this relation by presenting a new computational model of human spoken-word recognition, built using techniques from the field of ASR that, in contrast to current existing models of HSR, recognizes words from real speech input.

Computational modelling has proven to be a valuable approach in developing theories of spoken-word processing. In this paper, we focus on a particular class of theories in which it is assumed that the spoken-word recognition process consists of two consecutive stages, with an `abstract' discrete symbolic representation at the interface between the stages. In evaluating computational models, it is important to bring in independent arguments for the cognitive plausibility of the algorithms that are selected to compute the processes in a (...) theory. This paper discusses the relation between behavioural studies, theories, and computational models of spoken-word recognition. We explain how computational models can be assessed in terms of the goodness of fit with the behavioural data and the cognitive plausibility of the algorithms. An in-depth analysis of several models provides insights into how computational modelling has led to improved theories and to a better understanding of the human spoken-word recognition process.

Oral communication often takes place in noisy environments, which challenge spoken-word recognition. Previous research has suggested that the presence of background noise extends the number of candidate words competing with the target word for recognition and that this extension affects the time course and accuracy of spoken-word recognition. In this study, we further investigated the temporal dynamics of competition processes in the presence of background noise, and how these vary in listeners with different language proficiency (i.e., native and non-native) using (...) computational modeling. We developed ListenIN (Listen-In-Noise), a neural-network model based on an autoencoder architecture, which learns to map phonological forms onto meanings in two languages and simulates native and non-native spoken-word comprehension. We also examined the model's activation states during online spoken-word recognition. These analyses demonstrated that the presence of background noise increases the number of competitor words, which are engaged in phonological competition and that this happens in similar ways intra and interlinguistically and in native and non-native listening. Taken together, our results support accounts positing a “many-additional-competitors scenario” for the effects of noise on spoken-word recognition. (shrink)

Gottfried Wilhelm Leibniz (1646-1716), esprit universel et promoteur des sciences, est à la fois philosophe, mathématicien et diplomate. Passionné par le langage et le monde, il cherche en encyclopédiste à rendre compte de toutes les inventions et de tous les savoirs. Lors de son séjour à Paris - quatre années pendant lesquelles il rencontre Huygens et étudie Pascal -, il conçoit, en 1675, un projet original de création d'académies, plusieurs spectacles de divertissement. Imaginant des mises en scène ou cherchant à (...) régler la direction des casinos, le philosophe raisonne toujours en stratège. Pour lui, tout dans le monde est combinatoire. D'où son amour pour les jeux, qui associent signes et réseaux. Ainsi se dévoile une Europe savante et inventive qui anticipe notre monde relationnel et numérique. (shrink)

This article reports on the methodology for setting the Mexican User Satisfaction Index for Social Programs as tested in seven national social programs. The evaluation is based on Structural Equation Modeling. How satisfaction takes the central place of the SEM, which postulates its causes and effects, contributes to the increased validity and reliability of satisfaction indicators that allow benchmarking between social programs. The MUSI model is an adaptation of the American Customer Satisfaction Index model. The MUSI methodology includes qualitative and (...) quantitative techniques. The estimation model is by the Partial Least Squares. In each of the seven social programs, no statistical evidence was found to reject the main relationships postulated by the ACSI’s model: that Perceived Quality impacts Satisfaction, and Satisfaction impacts Trust. The improvement opportunity areas were also identified for each program. These results give valid and reliable feedback to public policies. (shrink)

The aim of this study was to examine preliminary evidence of the validity of the Trauma Reflective Functioning Scale and to investigate reflective functioning and attachment in pregnant women with histories of trauma, with a particular focus on the capacity to mentalize regarding trauma and its implications for adaptation to pregnancy and couple functioning. The Adult Attachment Interview was used to assess attachment, unresolved trauma and mentalization (measured as reflective function; RF) regarding relationships with attachment figures (RF-G) and trauma (RF-T) (...) in 100 pregnant women with histories of abuse and neglect. The majority (63%) of women had insecure attachment states of mind and approximately half were unresolved regarding trauma. Furthermore, the majority of women manifested deficits specific to RF-T. Their RF-T was significantly lower than their RF-G; the findings indicate that women with histories of childhood abuse and neglect do not manifest a generic inhibition of reflectiveness, but a collapse of mentalization specific to trauma. Low RF-T, indicative of difficulty in considering traumatic experiences in mental state terms, was associated with difficulty in investment in the pregnancy and lack of positive feelings about the baby and motherhood. In addition, low RF-T was also associated with difficulties in intimate relationships. Results of a regression analysis with RF indicated that RF-T was the best predictor of investment in pregnancy and couple functioning. In sum, the study provides preliminary evidence that RF-T can be reliably measured and is a valid construct that has potential usefulness for research and clinical practice. It highlights the importance of mentalization specifically about trauma and suggests that it is not the experience of trauma per se, but the absence of mentalization regarding trauma that is associated with difficulties in close relationships and in making the transition to parenthood.

This article discusses the place of sedation in the care of the terminally ill, as used in the practice of palliative care using case studies, clinical pragmatism forms the theoretical framework from which to elucidate the varying part that sedation plays in the overall management of a person facing the end of life. We contend that when used appropriately, sedation is an ethical and legitimate intervention that enhances comfort at the end of life and ought not sedate the person onto (...) “oblivion”. (shrink)

O LEITMOTIV FORTUNY E ODETTE: ESPAÇO E TEMPO NA TESSITURA DE PROUST Resumo A moda das roupas está plenamente integrada ao todo da obra de Proust, e é por essa razão que nos debruçamos sobre dois temas concernentes às roupas: o leitmotiv Fortuny, e a personagem Odette. O motivo Fortuny mereceu de Proust uma atenção delicada, pois emaranhado ao seu tecido literário, o desenvolvimento do tema manifesta uma minuciosa construção estética tramada por diferentes fios, que encontrarão em seu (...) término, a roupa e o tecido de Fortuny em consonância com a arte e as cidades, entidades refletidoras sobretudo do espaço afetivo tramado na tessitura proustiana. Em posição distinta, mas complementando o tecido literário, surge a personagem atemporal Odette, que não participa do leitmotiv; Odette, que, sem seguir uma moda, tem estilo, soube como poucas mulheres construir, por meio de sua representação indumentária sua própria identidade e alteridade, ou em outros termos, ser e estar no tempo. -/- THE FORTUNY LEITMOTIF AND ODETTE: A VIEW OF SPACE AND TIME ON PROUST TEXTURE -/- Abstract The fashion of clothing is fully connected into all Proust work, and it is for this reason which we descant over two issues concerning the clothes: the Fortuny Leitmotif, and the character Odette. Proust gave a very special attention to the Fortuny reason, due to – deeply in his literary thoughts – the developing of the theme evidences a thorough planning built by different kind of thoughts, which they will find in their end, the clothes, the Fortuny tissue in consonance to the art and the cities, reflecting entities especially about the affective space built by Proust texture. Adding to the literary issue, however in a different position, emerges the eternal character, Odette. She did not appear on leitmotif. She has style, even though does not follow fashion and she is one of the rare women, which know how to build her own identity and otherness through her clothing representation. In other words, being for real on her time. -/- . (shrink)

Proust reminds us many times in the pages of In Search of Lost Time that there is no such thing as a singular or unchanging self.1 When viewing the novel as a whole, this point is most evident in the journey of Marcel, the narrator, who has to become a myriad of Marcels before he reaches the library of the Guermantes and the discovery of what he must write about. But the theme is also prevalent in a more intimate reading (...) of the novel's many vignettes. Swann, for instance, cannot understand the torment he has gone through for a woman who wasn't his type precisely because he has ceased to be the Swann who desired Odette. Rather, the newfound subjectivity he inhabits at the end of Swann in Love takes him back to an... (shrink)
