Among which, Social Orienting (SO) and Joint Attention (JA) have proven to be good predictors of the development of sociability. The impairment of such functions has been strongly associated with the diagnosis of Pervasive Developmental Disorders (PDD). The present study has assessed the initial social communication skills (Social Orienting and Joint Attention) in children from 2 to 4 years old with typical development (n=19) and in children from 3 to 7 years old with Pervasive Developmental Disorder (n=17) paired by mental age. For the assessment the study has developed the PAISC - (Protocol of Assessment of Initial Social Communication). The results from the trials of the protocol have demonstrated that children with Pervasive Developmental Disorder have shown significantly worst performance in the Social Orienting and Joint Attention behaviors if compared to the children with typical development. Among the behaviors, the one that better distinguished children with Pervasive Developmental Disorder from the children with typical development was the Initial Joint Attention. The PAISC protocol allows detecting changes in the development of social communication in the first year of life, being an instrument for the early diagnosis and employment of intervention programs in the cases of Pervasive Developmental Disorders. / Comunicação Social Inicial compreende habilidades que surgem cedo no primeiro ano de vida. Entre essas habilidades, Orientação Social (OS) e Atenção Compartilhada (AC) têm se mostrado bons preditores do desenvolvimento da sociabilidade. Prejuízos nessas funções têm sido fortemente associados com o diagnóstico de Transtorno Invasivo do Desenvolvimento (TID). O presente estudo avaliou as habilidades da comunicação social inicial (OS e AC) em crianças com desenvolvimento típico de 2 a 4 anos (n=19) e em crianças com TID de 3 a 7 anos (n=17) pareadas pela idade mental. Para a avaliação o estudo desenvolveu o Protocolo de Avaliação da Comunicação Social Inicial PACSI. Os resultados obtidos nas provas do protocolo demonstraram que as crianças com TID apresentaram performance significativamente pior nos comportamentos de OS e AC, comparadas às crianças com desenvolvimento típico. Entre os comportamentos o que melhor discriminou crianças com TID das crianças com desenvolvimento típico foi o de Iniciação de Atenção Compartilhada. O protocolo PACSI permite detectar alterações no desenvolvimento da comunicação social no primeiro ano de vida, sendo um instrumento para o diagnóstico precoce e estabelecimento de programas de intervenção nos casos de Transtornos Invasivos do Desenvolvimento.

The results are related to the review of literature on the subject, concerning the investigation about the influence of joint attention on autism. Thus, studies published and indexed in the data bases MEDLINE, LILACS and SCIELO were previously identified. It highlights joint attention as a possible predictor of risk of children autism, and concludes that its development tends to occur in the first year of life. Joint attention represents an important type of communication, besides being a possible way for children to learn about things in their environment. / Identifica a produção bibliográfica editada em periódicos sobre atenção compartilhada, que é caracterizada como sendo a capacidade de coordenação triádica da atenção entre o ser, o outro e um terceiro evento, objeto ou símbolo. Os resultados são concernentes à revisão da literatura publicada sobre a temática, com a preocupação de investigar qual a influência da atenção compartilhada no autismo infantil. Para tanto, foram previamente identificados estudos publicados e indexados nas bases de dados analisadas MEDLINE, LILACS e SCIELO. Destaca a atenção compartilhada como uma possível indicadora de risco de autismo infantil e conclui que seu desenvolvimento tende a acontecer no primeiro ano de vida e representa um tipo importante de comunicação, além de ser um possível caminho para a criança aprender sobre as coisas em seu meio.

The present study was designed to examine differences in the effect of the number of children in the household (also known as “parity”) on the relationship between initiating joint attention (IJA) and language development. We reasoned that infants who are only children (i.e., in uniparous homes), relative to infants who have one or more siblings (i.e., in multiparous homes), would have more opportunity to engage in IJA, and would, therefore, acquire a larger number of object labels. We tested the hypotheses that: 1) there would be a positive correlation between the number of IJA bids and language overall, and 2) parity would moderate the IJA-language relationship such that in uniparous households, the aforementioned correlation would be stronger than in multiparous homes. Joint attention was measured using the Early Social Communication Scales (ESCS) Picture Book Task, and language was assessed through parental report on the MacArthur-Bates Communicative Development Inventory (MBCDI). There was no significant correlation between IJA and language on the whole, though there was a significant correlation for infants in uniparous homes between IJA and language. This finding partially supports Hypothesis 2 in terms of the IJA-language relationship being stronger in uniparous homes rather than multiparous ones, though it was only true for productive vocabulary. These null findings may provide reassurance for families with multiple children that their younger children are not at an IJA/language acquisition disadvantage.

A central issue in the study of primate communication is the extent to which individuals adjust their behaviour to the attention and signals of others, and manipulate others’ attention to communicate about external events. I investigated whether 13 chimpanzees (Pan troglodytes spp.), 11 bonobos (Pan paniscus), and 7 orangutans (Pongo pygmaeus pygmaeus) followed conspecific attention and led others to distal locations. Individuals were presented with a novel stimulus, to test if they would lead a conspecific to detect it in two experimental conditions. In one the conspecific faced the communicator, while another required the communicator to first attract the attention of a conspecific. All species followed conspecific attention, but only bonobos in conditions that required geometric attention following and that the communicator first attract the conspecific‘s attention. There was a clear trend for the chimpanzees to selectively produce a stimulus directional ‘hunching’ posture when viewing the stimulus in the presence of a conspecific rather than alone (the comparison was statistically non-significant, but very closely approached significance [p = 0.056]), and the behaviour consistently led conspecifics to look towards the stimulus. An observational study showed that ‘hunching’ only occurred in the context of attention following. Some chimpanzees and bonobos consistently and selectively combined functionally different behaviours (consisting of sequential auditory-stimulus-directional-behaviours), when viewing the stimulus in the presence of a non-attentive conspecific, although at species level this did not yield significant effects. While the design did not eliminate the possibility of a social referencing motive (“look and help me decide how to respond”), the coupling of auditory cues followed by directional cues towards a novel object, is consistent with a declarative and social referential interpretation of non-verbal deixis. An exploratory study, which applied the ‘Social Attention Hypothesis’ (that individuals accord and receive attention as a function of dominance) to attention following, showed that chimpanzees were more likely to follow the attention of the dominant individual. Overall, the results suggest that the paucity of observed referential behaviours in apes may owe to the inconspicuousness and multi-faceted nature of the behaviours.

Cette thèse s’intéresse au rôle de l’interface dans l’interaction humain-robot pour l’apprentissage. Elle étudie comment une interface bien conçue peut aider les utilisateurs non-experts à guider l’apprentissage social d’un robot, notamment en facilitant les situations d’attention partagée. Nous étudierons comment l’interface peut rendre l’interaction plus robuste, plus intuitive, mais aussi peut pousser les humains à fournir les bons exemples d’apprentissage qui amélioreront les performances de l’ensemble du système. Nous examinerons cette question dans le cadre de la robotique personnelle où l’apprentissage social peut jouer un rôle clé dans la découverte et l’adaptation d’un robot à son environnement immédiat. Nous avons choisi d’étudier le rôle de l’interface sur une instance particulière d’apprentissage social : l’apprentissage conjoint d’objets visuels et de mots nouveaux par un robot en interaction avec un humain non-expert. Ce défi représente en effet un levier important du développement de la robotique personnelle, l’acquisition du langage chez les robots et la communication entre un humain et un robot. Nous avons particulièrement étudié les défis d’interaction tels que le pointage et l’attention partagée.Nous présenterons au chapitre 1 une description de notre contexte applicatif : la robotique personnelle. Nous décrirons ensuite au chapitre 2 les problématiques liées au développement de robots sociaux et aux interactions avec l’homme. Enfin, au chapitre 3 nous présenterons la question de l’interface dans l’acquisition des premiers mots du langage chez les robots. La démarche centrée utilisateur suivie tout au long du travail de cette thèse sera décrite au chapitre 4. Dans les chapitres suivants, nous présenterons les différentes contributions de cette thèse. Au chapitre 5, nous montrerons comment des interfaces basées sur des objets médiateurs peuvent permettre de guider un robot dans un environnement du quotidien encombré. Au chapitre 6, nous présenterons un système complet basé sur des interfaces humain-robot, des algorithmes de perception visuelle et des mécanismes d’apprentissage, afin d’étudier l’impact des interfaces sur la qualité des exemples d’apprentissage d’objets visuels collectés. Une évaluation à grande échelle de ces interfaces, conçue sous forme de jeu robotique afin de reproduire des conditions réalistes d’utilisation hors-laboratoire, sera décrite au chapitre 7. Au chapitre 8, nous présenterons une extension de ce système permettant la collecte semi-automatique d’exemples d’apprentissage d’objets visuels. Nous étudierons ensuite la question de l’acquisition conjointe de mots vocaux nouveaux associés aux objets visuels dans le chapitre 9. Nous montrerons comment l’interface peut permettre d’améliorer les performances du système de reconnaissance vocale, et de faire directement catégoriser les exemples d’apprentissage à l’utilisateur à travers des interactions simples et transparentes. Enfin, les limites et extensions possibles de ces contributions seront présentées au chapitre 10. / This thesis is interested in the role of interfaces in human-robot interactions for learning. In particular it studies how a well conceived interface can aid users, and more specifically non-expert users, to guide social learning of a robotic student, notably by facilitating situations of joint attention. We study how the interface can make the interaction more robust, more intuitive, but can also push the humans to provide good learning examples which permits the improvement of performance of the system as a whole. We examine this question in the realm of personal robotics where social learning can play a key role in the discovery and adaptation of a robot in its immediate environment. We have chosen to study this question of the role of the interface in social learning within a particular instance of learning : the combined learning of visual objects and new words by a robot in interactions with a non-expert human. Indeed this challenge represents an important an lever in the development of personal robotics, the acquisition of language for robots, and natural communication between a human and a robot. We have studied more particularly the challenge of human-robot interaction with respect to pointing and joint attention.We present first of all in Chapter 1 a description of our context : personal robotics. We then describe in Chapter 2 the problems which are more specifically linked to social robotic development and interactions with people. Finally, in Chapter 3, we present the question of interfaces in acquisition of the first words of language for a robot. The user centered approach followed throughout the work of this thesis will be described in Chapter 4. In the following chapters, we present the different contributions of this thesis. In Chapter 5, we show how some interfaces based on mediator objects can permit the guiding of a personal robot in a cluttered home environment. In Chapter 6, we present a complete system based on human-robot interfaces, the algorithms of visual perception and machine learning in order to study the impact of interfaces, and more specifically the role of different feedback of what the robot perceives, on the quality of collected learning examples of visual objects. A large scale user-study of these interfaces, designed in the form of a robotic game that reproduces realistic conditions of use outside of a laboratory, will be described in details in Chapter 7. In Chapter 8, we present an extension of the system which allows the collection of semi-automatic learning examples of visual objects. We then study the question of combined acquisition of new vocal words associated with visual objects in Chapter 9. We show that the interface can permit both the improvement of the performance of the speech recognition and direct categorization of the different learning examples through simple and transparent user’s interactions. Finally, a discussion of the limits and possible extensions of these contributions will be presented in Chapter 10.

The presence of joint attention behaviors in babies has been correlated with the subsequent development of language and other symbolic behaviors. Deficit in joint attention behaviors has been considered a reliable marker of Autism Spectrum Disorder. The development of objective assessment measures is fundamental to the identification as early as possible of deficits in behaviors considered crucial to the infant human development. The absence of behavior analytic assessments, especially designed to investigation of joint attention behaviors let to the selection of an assessment instrument of prevocal behaviors, developed by developmental researchers and designed to the identifications of behaviors in babies before one year of age. The purposes of this study are (a) to analyze the contingencies involved in tasks of the assessment manual Early Social Communication Scale, (b) to investigate the development of joint attention behaviors in eight babies, between 9 to 15 months of age and (c) to propose a set of tasks to assess joint attention behaviors. The results of the instrument analysis indicated that tasks designed to the Initiation Joint Attention category presented less explicitly evocative conditions than to the Responding Joint Attention category and some of the behaviors assessed by the Initiation Joint Attention category didn’t accomplish the criterions to that inclusion. The performance of participants in the Responding to Joint Attention category progressively increased during the months assessed. And in the Initiation Joint Attention Category this data was identified only to the pointing behavior. To the others, it was not observed a regular pattern of behavior development, but it’s considered the influences of features related to the behavior classification and to the tasks. A set of tasks proposed considered the assessment of behaviors from the speaker and listener categories, with tasks that establish evocative conditions for all of behaviors in evaluation / A atenção compartilhada é o termo utilizado, pela literatura do desenvolvimento e cognitivista, para se referir a um conjunto de comportamentos (que envolvem gestos e contato visual), que permite ao indivíduo se engajar em relações triádicas, entre um par social e um objeto de interesse comum, a fim de compartilhar experiências. A identificação de comportamentos de atenção compartilhada em bebês tem sido correlacionada com o desenvolvimento posterior de linguagem e de outros comportamentos simbólicos. A falha na emissão de comportamentos de atenção compartilhada tem sido considerada um indicador confiável do Transtorno do Espectro Autista. O desenvolvimento de medidas objetivas de avaliação é fundamental para que se identifique o mais precocemente possível déficits em comportamentos considerados cruciais no desenvolvimento infantil de humanos. A ausência de avaliações analíticocomportamentais, especialmente delineadas para a investigação dos comportamentos de atenção compartilhada levou a seleção de um instrumento de avaliação de comportamentos pré-vocais, desenvolvido por pesquisadores do desenvolvimento e delineado para a identificação de comportamentos, antes de um ano de idade. Os objetivos deste estudo foram (a) analisar as contingências envolvidas nas tarefas do instrumento de avaliação Early Social Communication Scale, (b) investigar o desenvolvimento de comportamentos de atenção compartilhada em oito bebês, de 9 a 15 meses e (c) propor um conjunto de tarefas para avaliação de comportamentos de atenção compartilhada. Os resultados da análise do instrumento indicaram que tarefas delineadas para a categoria Iniciar Atenção Compartilhada apresentavam condições evocativas menos explícitas que para a categoria Responder à Atenção Compartilhada e que alguns dos comportamentos avaliados na categoria Iniciar Atenção Compartilhada não cumpriam com os requisitos para esta inclusão. O desempenho dos participantes na categoria Responder à Atenção Compartilhada diferenciou-se nos meses avaliados. E na categoria Iniciar Atenção Compartilhada este dado foi identificado apenas para o comportamento de apontar. Para os demais, não se observou padrão regular no desenvolvimento dos comportamentos, mas considera-se a influência de questões relativas a classificação dos comportamentos e das tarefas. O conjunto de tarefas proposto avalia os comportamentos nas categorias falante e ouvinte com tarefas que estabelecem condições evocativas para todos os comportamentos em avaliação

Hur föräldrar samspelar med barn kan ha stor påverkan på barnets språkliga och kommunikativa utveckling. Föräldrasensitivitet och mind-mindedness är två mått som mäter föräldrars samspel. Föräldrasensitivitet mäter förälderns förmåga att uppfatta och tolka barnets signaler och mind-mindedness innefattar förälderns användande av ord som handlar om barnets mentala processer. Dessa mentaliseringsyttranden kan vara intonade eller icke-intonade utifrån situationen och barnets sinnesstämning. I vilken grad föräldrars mind-mindedness och föräldrasensitivitet påverkar olika delar av den kommunikativa utvecklingen är till stora delar fortfarande okänt. Syftet med föreliggande studie var att undersöka om föräldrasensitivitet och föräldrars mind-mindedness korrelerar med kommunikativa förmågor, om mind-mindedness och föräldrasensitivitet korrelerar med varandra samt om några könsskillnader förelåg. Materialet bestod av 35 inspelade förälder-barndyader som observerats när barnen var ca 16 månader. För att mäta föräldrasensitivitet användes lyhördhetsskalan ”Lyhördhet eller icke-lyhördhet för barnets signaler”. För att mäta mind-mindedness kodades förälder-barndyaderna samt föräldrabeskrivningar utifrån manualen för mind-mindedness av Meins och Fernyhough (2010). De kommunikativa förmågorna mättes dels genom the Swedish Early Communicative Development Inventories och dels genom the Early Social Communication Scales. Resultatet visade att det förelåg samband mellan föräldrasensitivitet och kommunikativa förmågor. Såväl språkförståelse, kommunikativa gester samt delad uppmärksamhet korrelerade med föräldrasensitivitet. Beträffande föräldrars mind-mindedness, konstaterades ett samband mellan en hög andel icke-intonade mentaliseringsyttranden och bristande förmåga till delad uppmärksamhet. Vidare framkom samband mellan mind-mindedness och föräldrasensitivitet: en förälder med hög föräldrasensitivitet använde fler intonade mentaliseringsyttranden än en förälder med låg föräldrasensitivitet. Ett motsvarande omvänt samband uppstod mellan icke-intonade mentaliseringsyttranden och en låg nivå av föräldrasensitivitet, där en icke-lyhörd förälder använde fler icke-intonade mentaliseringsyttranden. Slutligen upptäcktes en könsskillnad som innebar att föräldrar använder fler icke-intonade mentaliseringsyttranden till pojkar än till flickor. / The way a parent interacts with his or her child can have a great effect on communication and language development of the child. Maternal sensitivity and mind-mindedness are two measures used for parent-child interplay. Maternal sensitivity measures the parent’s ability to accurately perceive and interpret the child’s cues while mind-mindedness involves the parent’s use of words and comments regarding the child’s internal state. These comments can be classified as appropriate or non-attuned regarding the situation and the child’s state of mind. To what extent mind-mindedness and maternal sensitivity affect different parts of the child’s communicative development is still mainly unknown. The purpose of the present study was to investigate if maternal sensitivity and mind-mindedness co-vary with communicative abilities, if mind-mindedness and maternal sensitivity co-vary with each other, and finally, if any gender differences was present. The material of the study consisted of 35 videotaped parent-child interactions, which were observed when the children were 16 months of age. To measure maternal sensitivity, the sensitivity scale were used, “Sensitivity vs. Insensitivity to the Baby's Signals”. To measure mind-mindedness, parent-child interplay and parental interviews were coded. The child’s communicative abilities were assessed with the Swedish Early Communicative Development Inventories and with the Early Social Communication Scales. The result showed a correlation between maternal sensitivity and language comprehension, communicative gestures and joint attention. A relationship was found between mind-mindedness and parents’ using more non-attuned mental comments and children’s decreasing ability to respond to joint attention. The results also demonstrated that a sensitive parent uses more appropriate mental comments than a parent who was insensitive. A reversed relationship was found between non-attuned mental comments and a low level of maternal sensitivity, where the insensitive parent used more non-attuned mental comments. Finally, a difference in gender was found, where parents use more non-attuned comments to boys than to girls. / FAS dnr 2008-0875

Thus we work with the multimodal envelope perspective, i.e., the fusion of three components of the dialogism look, gestures and vocal production that emerge simultaneously. We consider the concept of multimodality proposed by McNeill (1985) as a mixture of the gesture-vocal actions. The studies in language acquisition and in nonverbal communication postulate theoretical assumptions about linguistic, paralinguistic and extralinguistic elements in a dissociated way. The first ones had as primacy the observation of interlocutors speech and writing in various contexts. The second type was justified as a complement to the linguistic and the extralinguistic elements were considered as accessories used as aids to the speech. Our results show that the mother uses the multimodal composition to address herself to the child who interacts as she acquires the three basic components of the dialogism. / Esta produção teve como intuito acompanhar a emergência da língua enquanto instância multimodal em contextos de atenção conjunta vividos em situações naturalísticas de duas díades mãe-bebê, dos 07 aos 17 meses de vida da criança. Para isso trabalhamos com a perspectiva de envelope multimodal, ou seja, a mescla de três componentes da dialogia olhar, gestos e produção vocal que emergem concomitantemente. Tomamos como premissa a noção de multimodalidade proposta por McNeill (1985) como sendo a mescla das ações gesto-vocais. Os estudos em aquisição de linguagem e de comunicação não-verbal postulavam aportes teóricos a respeito de elementos lingüísticos, paralingüísticos e extralingüísticos de forma dissociada. Os primeiros tinham como primazia a observação da fala e da escrita de interlocutores em vários contextos. O segundo tipo era justificado como complemento do lingüístico e os elementos extralingüísticos eram considerados como acessórios usados como auxiliares da fala. Nossos resultados mostram que a mãe faz uso do plano de composição multimodal para dirigir-se à criança que, por sua vez, interage à medida que adquire os três componentes básicos da dialogia.
