Ontogeny of manipulative behavior and nut-cracking in young tufted capuchin monkeys (Cebus apella): a Perception-action perspective

How do capuchin monkeys learn to use stones to crack open nuts? Perception-action theory posits that individuals explore producing varying spatial and force relations among objects and surfaces, thereby learning about affordances of such relations and how to produce them. Such learning supports the discovery of tool use. We present longitudinal developmental data from semifree-ranging tufted capuchin monkeys (Cebus apella) to evaluate predictions arising from Perception-action theory linking manipulative development and the onset of tool-using. Percussive actions bringing an object into contact with a surface appeared within the first year of life. Most infants readily struck nuts and other objects against stones or other surfaces from 6 months of age, but percussive actions alone were not sufficient to produce nut-cracking sequences. Placing the nut on the anvil surface and then releasing it, so that it could be struck with a stone, was the last element necessary for nut-cracking to appear in capuchins. Young chimpanzees may face a different challenge in learning to crack nuts: they readily place objects on surfaces and release them, but rarely vigorously strike objects against surfaces or other objects. Thus the challenges facing the two species in developing the same behavior (nut-cracking using a stone hammer and an anvil) may be quite different. Capuchins must inhibit a strong bias to hold nuts so that they can release them; chimpanzees must generate a percussive action rather than a gentle placing action. Generating the right actions may be as challenging as achieving the right sequence of actions in both species. Our analysis suggests a new direction for studies of social influence on young primates learning sequences of actions involving manipulation of objects in relation to surfaces.

Language, action, and sensoriality: a multimodal analysis of interactions in inclusive sport climbing with visually impaired athletes

In sport climbing, athletes with vision impairments are constantly accompanied by their guides – usually trainers – both during the preparatory inspection of the routes and whilst climbing. Trainers are, so to speak, the climbers’ eyes, in the sense that they systematically put their vision in the service of the climbers’ mobility and sporting performance. The synergy between trainers and athletes is based on peculiar, strictly multimodal interactive practices that are focused on the body and on its constantly evolving sensory engagement with the materiality of routes. In this context, sensory perception and embodied actions required to plan and execute the climb are configured as genuinely interactive accomplishments. Drawing on the theoretical framework of Embodied and Situated Cognition and on the methodology of Conversation Analysis, this thesis engages in the multimodal analysis of trainer-athlete interactions in paraclimbing. The analysis is based on a corpus of video recorded climbing sessions. The major findings of the study can be summarized as follows. 1) Intercorporeality is key to interactions between trainers and athletes with visual impairments. The participants orient to perceiving the climbing space and acting in it as a ‘We’. 2) The grammar, lexicon, prosody, and timing of the trainers’ instructions are finely tuned to the ongoing corporeal experience of the climbers. 3) Climbers with visual impairments build their actions by using sensory resources that are provided by their trainers. This result is of particular importance as it shows that resources and constraints for action are in a fundamental way constituted in interaction with Others and with specific socio-material ecologies, rather than being defined a priori by the organs and functions of individuals’ body and mind. Individual capabilities are thus enhanced and extended in interaction, which encourages a more ecological view of (dis)ability.

Capturing temporality and intentionality in information systems

Information modelling is a topic that has been researched a great deal, but still many questions around it have not been solved. An information model is essential in the design of a database which is the core of an information system. Currently most of databases only deal with information that represents facts, or asserted information. The ability of capturing semantic aspect has to be improved, and yet other types, such as temporal and intentional information, should be considered. Semantic Analysis, a method of information modelling, has offered a way to handle various aspects of information. It employs the domain knowledge and communication acts as sources of information modelling. It lends itself to a uniform structure whereby semantic, temporal and intentional information can be captured, which builds a sound foundation for building a semantic temporal database.

Enhancing teaching and learning speech acts: action research of Japanese as a foreign language /

This action research observes a second year Japanese class at a university where foreign language courses are elective for undergraduate students. In this study, using the six strategies to teach Japanese speech acts that Ishihara and Cohen (2006) suggested, I conducted three classes and analyzed my teaching practice with a critical friend. These strategies assist learners toward the development of their understanding of the following Japanese speech acts and also keep the learners to use them in a manner appropriate to the context: (I) invitation and refusal; (2) compliments; and (3) asking for a permission. The aim of this research is not only to improve my instruction in relation to second language (L2) pragmatic development, but also to raise further questions and to develop future research. The findings are analyzed and the data derived from my journals, artifacts, students' work, observation sheets, interviews with my critical friend, and pretests and posttests are coded and presented. The analysis shows that (I) after my critical friend encouraged my study and my students gave me some positive comments after each lesson, I gained confidence in teaching the suggested speech acts; (2) teaching involved explaining concepts and strategies, creating the visual material (a video) showing the strategies, and explaining the relationship between the strategy and grammatical forms and samples of misusing the forms; (3) students' background and learning styles influenced lessons; and (4) pretest and posttests showed that the students' Icvel of their L2 appropriate pragmatics dramatically improved after each instruction. However, after careful observation, it was noted that some factors prevented students from producing the correct output even though they understood the speech act differences.

Russian language maintenance through bedtime story reading?: Linguistic strategies and language negotiation in Russian-French speaking families in Switzerland

This article proposes an interactional approach to the question of Russian language maintenance through the activity of bedtime story-reading in Russian-French bilingual families in French speaking Switzerland. Reading stories appears to be a language maintenance strategy commonly employed by the Russian speaking parent. The ritual and recreational moment of story-reading therefore becomes an opportunity for language learning. Drawing upon a language socialization perspective, this paper proposes an interactional analysis of the language use in the activity of story-reading. It shows how the language choice of the participants may be requested, negotiated and challenged during the interaction. The analysis further informs us about the language choice pattern and the bilingual competences in these families. We will gain insight into (Russian) language maintenance as a daily social and linguistic practice.

Conservadores ou progressistas: como o judiciário de Piracicaba/SP se posiciona nos pleitos pela proibição da queima da palha de cana-de-açúcar

Este estudo analisa os fatores, as tendências e as fundamentações jurídico-ideológicas que permeiam as decisões judiciais em Ações Civis Públicas, impetradas pelo Ministério Público do Estado de São Paulo (MPSP) e Federal (MPF), requerendo a proibição imediata da queima da palha de cana-de-açúcar, na região de Piracicaba/SP. Para isso, foram levantadas, junto aos órgãos jurisdicionais da cidade de Piracicaba, as Ações Civis Públicas impetradas em face de grandes usinas e agropecuárias dedicadas ao cultivo e industrialização da cana-de-açúcar, requerendo a proibição da queima da palha na lavoura desde o advento da Lei nº 7.347 de 1985 até 2014, ano em que finalizou-se a pesquisa empírica desta dissertação. Nesses padrões, a pesquisa arrojou a existência de quatro processos, dos quais foram extraídas para análise a totalidade de vinte-e-um (21) manifestações judiciais. O marco teórico-metodológico empregado foi a abordagem marxista da filosofia da linguagem, perspectiva capaz de proporcionar uma fecunda imersão não só no que se diz, mas nas condições de produção desse dizer, valorizando a função socioideológica da palavra, permitindo vislumbrar a visão social de mundo de quem a emprega ou do grupo social ao qual o autor pode ou não pertencer (VOLOCHINOV,1929; GOLDMANN, 1979). Conclui-se que, nos pleitos judiciais pela proibição imediata da queima da cana-de-açúcar em Piracicaba/SP, o Poder Judiciário se mostra majoritariamente conservador, arguindo e decidindo pela continuidade da prática em evidente defesa do setor sucroalcooleiro. No entanto, se reconhece a importância do tímido mas importante viés progressista por parte do judiciário, uma vez que somente nas contradições presentes nas diferentes práxis jurídicas pode avançar-se no processo permanente de construção de um direito comprometido com a obtenção de igualdade e justiça social.

Muntlig framställning : att tolka och förstå kunskapskraven i nationellt prov SVA 1

Den här studien har haft som syfte att studera om kvalitetskraven i betygsskalan stämmer överens mellan nationellt prov i SVA1 och motsvarande kursplan svenska som andraspråk 1 (SVA1) samt på vilket sätt det nationella provet underlättar tolkningen av kunskapskraven i kursplanen för SVA1. Undersökningen begränsar sig till att omfatta enbart den muntliga delen, delprov A muntlig framställning. För att beskriva och analysera vilka kunskaper som anses vara eftersträvansvärda i muntlig framställning har en kvalitativ innehållsanalys genomförts som ger en grundmodell till den efterföljande kunskapsanalysen. Resultaten från studiens innehållsanalys visar fram en hur processen kring den muntliga framställningen utgår från den retoriska arbetsmodellen med ett gediget förberedande arbete som följs upp med anförande och avslutas med elevresponser. Resultatet från kunskapsanalysen visar hur eleverna behöver behärska en kombination av kunskapsformerna episteme, techné och fronesis för att uppfylla betygskraven på de högre nivåerna. Studiens slutsatser är att kvalitetskraven stämmer överens mellan det nationella provets bedömningsmatris och kursplanen i svenska som andraspråk 1 (SVA 1) vad gäller bedömningen av elevens språkliga kvaliteter. Dessutom går det att dra slutsatsen att de krav på anpassning till det retoriska sammanhanget också är krav som återfinns i kursplanen men beskrivs mer allmänt i ett språkutvecklande perspektiv vilket underlättar tolkningen av kunskapskraven i kursplanen. Studien visar hur eleven för att få det lägsta betyget (E) behöver kunskaper om en retorisk framställning och att eleven kan presentera ett förberett innehåll inför en publik.

Effetto crowding e dislessia evolutiva: un confronto inter e intra-linguistico

Crowding is defined as the negative effect obtained by adding visual distractors around a central target which has to be identified. Some studies have suggested the presence of a marked crowding effect in developmental dyslexia (e.g. Atkinson, 1991; Spinelli et al., 2002). Inspired by Spinelli’s (2002) experimental design, we explored the hypothesis that the crowding effect may affect dyslexics’ response times (RTs) and accuracy in identification tasks dealing with words, pseudowords, illegal non-words and symbolstrings. Moreover, our study aimed to clarify the relationship between the crowding phenomenon and the word-reading process, in an inter-language comparison perspective. For this purpose we studied twenty-two French dyslexics and twenty-two Italian dyslexics (total forty-four dyslexics), compared to forty-four subjects matched for reading level (22 French and 22 Italians) and forty-four chronological age-matched subjects (22 French and 22 Italians). Children were all tested on reading and cognitive abilities. Results showed no differences between French and Italian participants suggesting that performances were homogenous. Dyslexic children were all significantly impaired in words and pseudowords reading compared to their normal reading controls. Regarding the identification task with which we assessed crowding effect, both accuracy and RTs showed a lexicality effect which meant that the recognition of words was more accurate and faster in words than pseudowords, non-words and symbolstrings. Moreover, compared to normal readers, dyslexics’ RTs and accuracy were impaired only for verbal materials but not for non-verbal material; these results are in line with the phonological hypothesis (Griffiths & Snowling, 2002; Snowling, 2000; 2006) . RTs revealed a general crowding effect (RTs in the crowding condition were slower than those recorded in the isolated condition) affecting all the subjects’ performances. This effect, however, emerged to be not specific for dyslexics. Data didn’t reveal a significant effect of language, allowing the generalization of the obtained results. We also analyzed the performance of two subgroups of dyslexics, categorized according to their reading abilities. The two subgroups produced different results regarding the crowding effect and type of material, suggesting that it is meaningful to take into account also the heterogeneity of the dyslexia disorder. Finally, we also analyzed the relationship of the identification task with both reading and cognitive abilities. In conclusion, this study points out the importance of comparing visual tasks performances of dyslexic participants with those of their reading level-matched controls. This approach may improve our comprehension of the potential causal link between crowding and reading (Goswami, 2003).

O contributo da arte/expressão plástica na inclusão de alunos com dificuldades de aprendizagem específicas

Com este estudo, pretendeu-se realizar uma reflexão sobre a problemática dos alunos com Dificuldades de Aprendizagem Específicas (DAE) e sua inclusão na comunidade educativa. Para isso, procurou-se resposta à pergunta inicial “Qual o contributo da Arte/Expressão Plástica, na inclusão de alunos com Dificuldades de Aprendizagem Específicas”. A intervenção, passou por trabalhar a Expressão Artística com sete alunos do segundo ciclo, com DAE, integrados numa Oficina de Artes, denominada “Oficina SentirArte”, com recurso a estratégias de intervenção diversificadas e motivadoras. Atendendo à problemática proposta a estudo, e à questão de partida à qual se pretendeu responder, recorreu-se a um estudo quase-experimental, com pré-teste e pós-teste, numa perspetiva de Investigação-Ação, em que a Expressão Plástica, proporcionou a estes alunos a exploração das suas capacidades e o seu desenvolvimento, servindo para descobrir a emoção estética que reside, justamente, na satisfação que todos experimentam ao sentir-se capazes de explorar ao máximo as próprias capacidades de perceção e expressão. Concluiu-se, através de observação direta, da aplicação de um inquérito por questionário e de uma entrevista aos alunos, que a Expressão Artística e nomeadamente a Expressão Plástica teve um papel primordial, quer na promoção de competências como a de comunicação, a criatividade e a socialização, quer na da autoestima, da autoconfiança e do autoconceito, quer na inclusão destas crianças na escola e até na sociedade.
