Liminal spaces and narratives of voice and body in infant vocal interchange (commentary on morioka)

Abstract: This paper explores the heuristic value of the Japanese concepts utushi and ma, as they are described by Masayoshi Morioka (2008), for the study of vocal interaction between young infants and adults. Intersubjective engagement between infants and communicative partners is thought to be based on a subtle attunement of temporally organised gesture and vocal expression. Voice is seen as a fundamental matrix for cultural belonging rooted in biological motives for sharing experience before and beyond the symbolic meanings of language-based communication. The process of everyday spontaneous vocal interchange between infants and close others, situated within increasingly familiar social and cultural frames, thickens intersubjective experience. The infant voice acquires a 'grain' and polyphonic cultural overtones. It is proposed that the semiotic processes of cultural grounding in early infancy are based on a 'communicative musicality' (Malloch, 1999-2000) that supports nonverbal narrative meaning-making involving well-coordinated expression of voice and body in playful motivated exchange.

High speed implementation of a three-dimensional shape profiler with submillimeter precision using a digital light processing device and a new efficient algorithm for absolute phase retrieval

Abstract: The processing of structured light images in real time is a challenging task for the development of three-dimensional (3-D) shape measurement methods. This paper presents a high speed and low-cost optical profiler implemented using a projection method based on the use of a digital light-processing device to illuminate the object to be measured. The image processing of the reflected structured light pattern allows potential real-time capabilities. The proposed method of absolute phase retrieval for unwrapping the relative phase uses a single additional staircase intensity pattern to determine and correct 2π discontinuities in the phase. Good results are obtained when the method is compared to another which uses three additional fringe patterns to determine the stair phase and then the absolute phase. Since the proposed technique uses only one extra pattern instead of three, it is less costly in terms of computation complexity and is thus faster. The hardware of the developed fringe projection system for a 3-D macroscopic reconstruction is presented and the performance of the method is evaluated. Simulated and experimental results are presented and compared to the other absolute phase-retrieval method. The proposed method is suitable for measuring 3-D object surfaces for a possible implementation in real time.

Le Rorschach Système Intégré en Neuropsychologie : articulation du cognitif et de l'affectif

Abstract: Resume Depuis les annees 1920, le test du Rorschach a ete largement utilise pour l'etude de populations neurologiques. Cependant, avec les avancees dans le champ de la neuropsychologie dans les annees 1960, son utilisation n'a plus ete consideree comme appropriee dans ce contexte. Plus recemment, avec le developpement du Systeme Integre d'Exner et son paradigme cognitiviste de resolution de probleme, plusieurs auteurs ont reconsidere le test a la lumiere de la neuropsychologie contemporaine, non seulement comme un outil neuropsychologique cognitif, mais aussi comme un instrument utile pour l'etude des rapports entre fonctionnement cognitif et affectif, et comme un instrument capable de transcender les evolutions theoriques et paradigmatiques en neuropsychologie et en psychologie de la personnalite.
