Full textDuring development, the child modifies his cognitive and motor organization by its intentional and functional activities (explorator behavior) in a linear fashion-nonlinearity, a method of self-organization and method of stability-instability. These principles can disrupt the child's behavior and cognitive and cognitive function in school learning. We are particularly interested in classroom attention (sustained and selective), necessary to mobilize in order to learn at school. How does he adapt to the situationnal context ? How he integrates and does different information collected in this environment to maximize its attention ? How and what strategies can be used to control his attention ? To seek attention and selective attention effective, it is neccessary to have learning conditions with stable and adequate space for actions promoted, concrete, to discover and use the intrinsic properties of the task. What we will develop guidelines with assistance through tasks in mathematics and French from CP to CM2. . . We try to understand, after measuring sustained attention and attention selective how these attentions are mobilized and particulary depending on the school and family environment and development. We try to understand if they are functional to support the child in school learning

Full textThe selection of an information in the environment requires the orienting of spatial attention and the adjustment of the attentional window to the size of this information. These two attentional mechanism are crucial for the processing of letter strings. The aim of the thesis was to study the development of the ability to orient spatial attention and to reduce the size of the attentional window of processing continues to develop in children until at least the age of 9. Nonetheless, these attentional mechanism allow the processing of letter strings in children who learn to read. Reading-specific attentional processes seem to develop in the first year when learning to reading, and modified during following years, in relation with the development of attentional control and the acquisition of an orthographic lexicon

Full textABSTRACTDevelopmental dyslexia is a neurodevelopmental disorder that affects written language learning of about 10% of school-age children. During the last years, several studies have shown the presence of oculomotor abnormalities in dyslexia. However, several questions about the oculomotor performance of dyslexic children are still unanswered.We conducted three studies to examine eye movements of dyslexic children with respect to non-dyslexic age-matched children. In the first of our study, we investigated vertical saccades performance in dyslexic children. The results showed that, dyslexic children had longer latencies, poor precision and slow saccadic speed with up / down asymmetry. Studies 2 and 3 respectively allowed us to enlarge the investigation of visual fixation as well as visual-auditory phonological capabilities in dyslexic children. We reported a low quality of visual fixation and visual-auditory phonological recognition in children with dyslexia compared with the non-dyslexic children.Taken together, all these findings suggested, in dyslexic children, an immaturity of the magnocellular visual system, as well as of the cortico-subcortical structures responsible for oculomotor performances. Attentional capabilities, that are poor in dyslexic children, would be also explained their oculomotor deficiencies reported. Thus, we proposed oculomotor rehabilitation that could be able to improve reading skills in dyslexia.Key words: Eye movements, saccades, fixations, visual system, visual cortex, cortical and sub-cortical structures, attention, developmental dyslexia

Various works found that autistic children exhibited dysfunctionings in this abilities. The objective of this research was to show evidence of that joint attention disorder in autistic children implied further psychological disorders such as symbolic play and theory of mind. Analysis of data from a longitudinal study performed based upon home movies and psychological examinations of autistic and normal children showed a relationship between the intensity of joint attention disorder, symbolic play and the theory of mind developmental delay

Full textAttention during second year a new method attentional mechanisms are often considered an important factor in scholastic difficulties. While researchers agree with importance of this study, little researchs investigates it, its the conceptual status is not clear. A global definition of attention does not exist; it is more common to speak of attentional mechanisms, each of wich corresponding to a particular task and definition. However, with increasingly younger subjects, on there is less distinction between attentional processes, and much less research has been conducted. So, few studies investigate attentional mechanisms during the second year of life. We think that this is a result of methological problems characteristics of this age. We have created a new method, using tactil screen with wich we can present differents tasks and thus differentiate several attentional mechanisms in infants as young as 12 months. This method permits us to investigate aspects of attention suh as maintenance, focalisation of attention, the select of pertinent information, and the effect of a distractor

Full textA visual scene has different hierarchical levels of structure, from the most local elements to the largest global level of organization. To study the mechanisms that underlie global and local perception, Navon (1977) used compound stimuli, consisting of large letters composed of a suitable arrangement of small letters. In adults, two very reproducible effects were found: a global advantage and a global interference. These have been called the “global precedence effect” (GPE). This thesis aimed at studying interactions between global-local and identification processes. In a first experiment, we used compound stimuli composed of objects and non-objects. We showed that the global precedence effect could be inversed depending on the meaningfulness of the stimuli. In a second experiment we found, first, that the global level was always processed faster than the local level, irrespective of the meaningfulness of the material. Second, we found that the interference effect occurred only with meaningful stimuli. These results suggest that the GPE involves, on the one hand, “sensory mechanisms” and, on the other hand, “cognitive mechanisms”. We also studied how global and local processes evolve during childhood, according to the meaningfulness of the stimuli. We found evidence for an evolution from local preference at 4 years of age to adult-like global preference at 9 years of age. Moreover, we found that the effect of identification processes during the global-local task evolves during childhood. Finally, a forth study revealed that the way in which people deal with global and local information varies according to the inter-individual characteristic of field dependency. All these results underscore the fact that looking for meaning is crucial in the perception of visual scenes

Full textIt has been proposed that a deficit in cognitive flexibility is specific to autism. Several recent results undermine this hypothesis and put the emphasis on joint attention deficits. These two forms of flexibility and the link between them were studied in 53 children with autism and compared to 49 children of a clinical control group and to 74 children of a normal control group. Matched on mental age, these children were divided into three age groups, ranging from 18 to 84 months. In addition, a longitudinal study was conducted. In the autism group, our results show specific deficits in joint attention, but not in cognitive flexibility. Furthermore, these two forms of flexibility don't seem to be associated in typical and atypical development. These results are discussed from a developmental perspective and they bring up the hypothesis of an early deficit in social orienting in autism

Full textAttention has three components : selective attention, sustained attention and divided attention. It’s an abundantly studied field in psychology but mainly in the visual modality. The main goal of our work is to test the auditory attentional capacities and more precisely selective attention and divided attention. We used detection task, counting task and comparison task (simple and multiple choice). In these tasks we presented to subjects complex sequences contained two up to six environmental sounds. According to theory participants have increasing capacities : children, adults, musicians and adult with autism. Results in selective attention show correct performances for most part of tested populations. No subjects even if they have poorer results respond by chance. Regarding divided attention studies show similar patterns : a rapid decrease from sequences of two sounds. Moreover we demonstrate the existence of an attentional limit 4 +- 1 sounds. This one is flexible depend on factors. If principally endures inhibitions and a few facilitations. An exploratory study performed with autists can adduce extra elements to understand the attentional limit

Full textFor current cognitive psychology research, working memory is a central part of the cognitive system. Studying the constraints of the operation and of the development of this memory shades on the mechanisms underlying children’s general cognitive system. The aim of the research described in this doctoral thesis is to determine the factors constraining children’s working memory operation by studying the developmental and inter-individual differences of spans. The three first studies test the main theories that account for the developmental increase of working memory spans. Our results allow us to conclude that this increase of developmental recall performances is mainly due both to a developmental increase of cognitive attentional resources and to a automatization of processes. In a forth experiment we test with children, a new working memory model which assumes that spans depend to the density of the processing component to performed at the same times as the memorization. The last experiment compares developmental and inter-individual span differences. Results indicate that when the difficulty of the processing component of the working memory task is adapted to the abilities of each participant, inter-individual differences nearly vanish. Our set of results put forward that it is not the same process that underlies the developmental and the inter-individual working memory differences

Full textThe aim of this thesis is to study the development of temporal behaviors and their changes according to children's contexts and cognitive abilities, in order to propose a model of the distortions of time judgment. A set of 9 experimental studies were carried out in this thesis belonging to 3 main axes. Axis 1 – Development of time and neuropsychology. This axis aims to examine the role of cognitive abilities (attention, memory, processing speed) in the distortions of time judgment in children. For this reason, children aged from 5 to 8 years, as well as adults, have been subjected to paradigms of attention distractor and double-task, with competing tasks of different natures, either non-temporal (color discrimination) or temporal (discrimination or reproduction of durations). Children's abilities were assessed using different neuropsychological tests. The results show that time distortions (underestimation of time) in children are related to their limited attentional abilities, particularly to their abilities in selective attention in the case of dual tasks and to that of inhibition in attentional distraction. Thus, two attentional mechanisms impact the judgment of time, one linked to the triggering of the "attentional switch" time processing and the other to the "attentional gate" attentional resources. Nevertheless, when the subject has to treat two durations in parallel, one does not observe temporal underestimation, contrarily, an overestimation of the time is revealed. Moreover, this distortion of time is no longer linked to the cognitive abilities of the child, although it is more difficult for the child to perform a second temporal task than a second non-temporal task. This suggests the existence of an internal clock system (or multiple clocks) capable of independently processing multiple durations. However, our results show that attentional processes interfere with this system, thus causing temporal distortions. Axis 2 - Time and context. Within the framework of this axis, we studied the influence of the temporal context on the distortions of time in the child and the adult, according to the order of presentation of the durations in the experimental session, their sensory modality (visual or auditory), and the social significance of the stimulus to be estimated (state of the other). The results show the strong influence of the contexts on the duration’s judgment in the young child. In fact, they show greater time overestimation when the durations vary from sensory modality from one trial to another. Their temporal judgment is also more influenced by the value of the durations presented previously. They are also subject to more temporal distortions, incorporating in their estimations the perceived state of the other (movement, emotion), although the explicit acquisition of the theory of mind accentuates these distortions. Moreover, our results show that the amplitude of these contextual distortions of time is directly related to the cognitive abilities of the child, notably of his attention and working memory abilities. These results testify to the determining influence of the development of cognitive functions on the judgment of time. Axis 3 - Time and modeling. In this third area, a series of neural networks (Simple Recutrent Network and Multi-Layer Perceptron) has been undertaken to propose a new developmental model of time judgment, combining automatic internal clock processes with interfering cognitive processes. Our model allows us to predict significantly the distortions of time in humans at different ages. Our model is therefore able to simulate temporal judgment bias based on inter and intra-individual cognitive differences. This original model should make it possible to systematically study the difficulties of time judgment in different contexts and in various populations with or without disorders

Full textExecutive attention develops rapidly during the preschool period, during which the first signs of atypical developmental trajectories can appear. Executive attention disorders, along with sensory atypicalities, particularly tactile, are frequently reported in neurodevelopmental disorders. The aim of this doctoral work was to explore the connections between executive attention and tactile sensory processing in preschool-aged children. In a first study, we identified a relationship between the tactile sensory processing score, measured by the Dunn Sensory Profile questionnaire, and the BRIEF-P overall executive composite score. To further investigate this connection at the neural level within our study population, we adapted a computerized executive attention task called the Preschool-ANT, which is compatible with EEG measurements. In a second study, we utilized this new tool to assess the links between executive attention and tactile sensory processing in EEG. We designed a vibrotactile oddball-omission paradigm to measure sensory prediction and its associated mechanism, repetition suppression. We found links between tactile repetition suppression and conflict responses in the Preschool-ANT in the fronto-central region. Furthermore, tactile repetition suppression in the somatosensory region is correlated with inhibition and planning in everyday life situations (BRIEF-P). Lastly, the detection of deviant tactile stimuli showed links both with the difference in late positive neural responses in the Preschool-ANT and emotional control in daily life situations (BRIEF-P). This doctoral work emphasizes the importance of studying the quality of tactile sensory processing from a very young age to understand the emergence of atypical developmental trajectories. It offers new perspectives for designing new assessment tools and promoting early interventions targeting sensory disorders to simultaneously reduce their impact and prevent attentional disorders

Full textThe purpose of this thesis is to study the interactions between the sensory-motor and cognitive control systems of action (Paillard, 1992). Distortions of visual information in pointing tasks are used to reveal the structure of visuo-motor conversion and the systems of planning-control model (Glover, 2004). This paradigm allows to analyze how environmental and cognitive constraints alter interactions between the two levels of control, and to separate the spatial and dynamic dimensions introduced by Glover's model (Boy et al., 2005). Our first objective was to study the adaptation of this model when experimental conditions were changed. Studies 1, 2 and 3, adults achieved pointing movements in conditions of 0 ° to 180 ° rotations, with (I) or without vision (II), or with vision and attentional instructions (III). These studies show that (1) a bidirectional structure of conversion is always used, (2) the dissociation of performance dimensions is observed in the absence of vision and disappears when rotations increased, indicating a cognitive control of movements (3) the visual conditions have a greater influence on the control of action than attentional instructions. Our second objective was to study the interaction between the development of cognitive representations (Study 4) and the control of action at 5 years of age (studies 5 and 6, respectively replicating studies 1 and 2). These studies do not distinguish dimensions of performance. In addition, the study 6 shows that sensory-motor level configure the cognitive level. This thesis thus highlights that the plasticity of control system in adults depends on situation and suggests that the motor functions allow the development of spatial representations in childhood

Full textScientific Background: Defined as a complex syndrome, combining attentional and behavioral difficulties, ADHD has nowadays become a widespread disorder affecting approximately 3.5% of children in France. The divergent approaches, as well as the various therapies, involve research in different fields. Biofeedback approaches have coughed our attention, since innovative and sensitive to the integration of the subject in his care journey. The approach based on cerebral activity (neurofeedback) has been explored in many aspects, however its respiratory counterpart has remained aside, thus a line of research to be explored. Problem: Does therapeutic support based on a biofeedback tool reduce the intensity of attentional dysfunction symptoms in children with ADHD? Method: The study focuses on the evaluation of a respiratory biofeedback protocol with an interactive and multisensory device (Garden - Ullo) in the reduction of the expression of symptoms related to AD / HD in children diagnosed and aged between 8 and 11 years. The 17 participants in this randomized, crossover clinical trial, are divided into two intervention groups (immediate and delayed) and the study is divided into two phases. During the intervention phase, activities involving attention are proposed through exercises involving three modalities: cooperation, cognition, and self-regulation. The evaluation phase allows it to determine the evolution of symptomatic manifestations during the study. Results : The results from this randomized trial highlights an overall decrease in the scores obtained on the different scales, testifying to the short-term benefits of the sessions carried out. The maintenance of these benefits in the medium term is however reduced, remaining perceptible for a sub-category of patients, those with an high potential profile. Conclusions: The proposed protocol allows to decrease symptomatic manifestations and functional impacts related to ADHD, in correlation with the patient's profile and comorbidities. This preliminary study leads to new questions about the functioning of ADHD, for which a covariance can be identified between behavioral and cognitive manifestations of the disorder

Following Bronfenbrenner'smodel, three. Attention and its variations were assessed using cancellation tests. Data relating to group leisure activities and parental work were collected from families using questionnaires. The effects of three types of school-day organisation were compared for 366 children. Frequency indices for participating in group leisure activities were obtained from 614 children. The study of the parental work effects involved measuring the length of the work-day of both parents (199 children), the constraints of work organisation, and the professional stress of the mother and father (460 children and their parents. ). The results confirm the role adjusting weekly school hours plays in a child's attention level and its variations, unrelated to gender. With regard to effects of group leisure activities on school attention , a critical threshold was identified in the youngest children, while beneficial effects were observed in older children. The length of parental time available to children resulting from parental work organisation, organisational constraints and professional stress influenced the child's attention at school. The effects of the mother's or father's work can be differentiated. The child's age would appear to be a moderating variable on all the relationships studied. The value of an ecosystem-based approach that models the environmental effects and their interactions on the child's psychological rhythms will also be discussed

Full textOur work focused on the study of auditory orienting attention cues (with tone cues and verbal cues) in dichotic listening situations across development. Four experiments were carried out with 8 to 12 years old children and with adults. If adults appeared to benefit from the use of tone cues as much as the use of verbal cues to improve their performance of identification in both ears, and thus to improve their cognitive control, however, only 9 years old children took advantage of verbal cues to orient more efficiently their attention and resolve cognitive conflicts. Below this age, only tones cues helped the children to orient and control their attention to the indicated ear.Altogether our results reveal that (a) auditory orienting capacities develop in synergy with cerebral development (the maturation of the prefrontal cortex increases at around 9 years of age), and that (b) verbal cues lead to an efficient orientation of attention and high performance of identification in both ears, even under the age of 9.We suggest that the facilitator role of verbal cues could result from the pre-activation of the top-down processes that they involve. Indeed, top-down processes are essential for cognitive control. Therefore, the presentation of this type of cues would enhance the activation of processes that are not so easily recruited by young children. The immaturity of the pre-frontal cortex of children below 9 years of age could explain the difficulties encountered by this age group

Full textBenign idiopathic partial epilepsies of children are associated with a favorable prognosis because of rare seizure and usually recovery during adolescence. The benign nature of these syndromes is questioned because of learning difficulties and subtle cognitive deficits, frequently reported in this population. We study the incidence of the epileptic discharges on the cognition, and observe their influences on brain organization and cognitive functions. We propose computerized tests to patients with centrotemporal spikes (BECT) mainly localized in one of both hemispheres and occipital discharges, Panayiotopoulos syndrome (PS), to estimate verbal, visuo-spatial and visuo-attentional skills, as well as three visual imagery processes still never studied in these syndromes. Behavioural data strengthen the idea of a specific disturbances according to the hemispheric lateralization of the discharges and confirm their incidence on the organization of the functional hemispheric asymmetry associated with the studied functions. Furthermore, we show that PS has a particularly negative impact on the visual imagery process, important skills in the child's academic success and enrichment of his imagination. Our results are consistent with the current questioning of the benign nature of epilepsy on the cognitive level. Compare the deficits and the functional hemispheric asymmetry according to the main localization of discharges gets new arguments for a specific impact of the epileptiform activity, because only the cognitive mechanisms underlain by the concerned regions are disrupted. This provides evidence to explain the learning difficulties identified in these children, and encourages them to provide educational facilities

Full textThis dissertation studies writing under the metacognitive and metasubjective perspectives from Pascual-Leone’s Theory of Constructive Operators (1976, 1984, 1987, 1989, 1995, 1997, 1998, 2000, 2001, 2012, 2013) et d’Efklides (2001, 2002, 2006, 2008, 2011, 2013). Research on writing emphases the role working memory plays on the processes underlying it (cf. Alamargot & Chanquoy, 2001 for a review of the literature ; Olive, 2012), namely how the limited capacity of working memory affects children’s difficulties in writing. The notion of guided training (Pascual-Leone & Johnson, 2011) is here adopted suggesting the explicit implementation of metacognition, generally defined as thinking about thinking (Flavell, 1979), to manage mental attention resources while enhancing working memory performance, and as a consequence, written performance.This being said, the following questions apply: does training primary school children to develop metacognitive knowledge and abilities contribute to activate (inhibit) (non)pertinent knowledge while dispelling their feeling of difficult about writing?The experimental studies conducted within this research focus on the metaconsctructive system of the theory of constructive operators: the learning system, the attention system and the personal system. Results show that 3rd, 4th and 5th graders are able to develop new metacognitive knowledge about writing, furthermore, primary school children succeed in better handling the cognitive resources required by the task

We have been able to compare the levels and the variations of attention in various reception facilities apart from school time and the effects of their frequentation on the levels and the variations of the attention in class near 713 childrens. The results indicate a positive influence of the frequentation of the collective receptions on the installation and the evolution of the psychological rythmicity, results which must moderate and be moderated according to factors' such as the age and the zone of education of the school. The interest of the frequentation of the collective receptions for the psychological rythmicities of the child will be discussed

Full textThe aim of this study was to analyze the temporal coordination between the organization of the maternal performance (singing and hand gesturing), the visual attention and vocalization of the infant at 3- and 6-months during sequences of the French ‘action-song’ ‘les marionnettes’. The word ‘action-song’ is used to refer to interactive routines that combine hand gestures coordinated with a baby song. Infant-directed singing has been shown to be among the first musical stimulations addressed infants. Experimental studies have demonstrated that it possesses several functions and that one of them is maintaining the infant’s attention. Action-songs emerge in interactions at about 4-months. Experimental studies have proved that the infant exhibits the ability to share her attention between the mother and another object of interest, in particular when it is a familiar object that the mother holds in her hands. Actions-songs appear to be a natural situation that allows us to study this ability. We tested the central hypothesis that the hierarchical levels of maternal singing performance would provide a frame that would organize the dynamic variations of the infant’s visual attention. Moreover the infant would vocalize at specific moments of the musical structure of maternal singing. We studied the exchanges of the same dyads at 3- and 6-months to explore the developmental trajectory of the coordination between the temporal organization of the maternal performance and the infant’s visual attention.We studied the interactions of 20 dyads at 3 months (12 boys and 8 girls) and of 18 of those dyads at 6 months (10 boys and 8 girls). We performed both video and acoustic microanalyses to study the dynamic variations of infant’s attention during the action-song. Thus, each gaze orientation of the infant was associated with a specific element of the maternal singing. Our results showed that maternal singing was articulated at three hierarchical temporal levels (verse, line, pulse) both at 3- and at 6-months. At 3 months the infant’s attention was oriented mainly towards the mother’s face. The variations of the infant’s attention were coordinated with the phrasing of maternal singing and the infant reoriented her attention towards the hands just before the end of the verse. Infants’ vocalizations also occurred at the end of the verse. At 6-months, infants were more attentive to the mother’s hands. Six-month-olds reoriented her attention towards the mother’s face at the end of the verse. Infants’ vocalizations were synchronized with pulse of the maternal singing. Furthermore our results exhibited gender differences at 3- and at 6-months. The performance of mothers of boys was more regular than the performance of mothers of girls. We suggest that actions-songs provide a frame that scaffolds the ability of the infant to share her attention between the mother’s face and hands

It aims at showing, in a developmental and differential perspective, the impact of the moment of daily performance, and weekly variations of sleep duration, according to age, sex and geographic background of the children. In order to be able to conduct the identification of the performances, we are able to measure changes in attention in two countries namely: Iraq and the United Arab Emirates. In order to proceed with the identification of performances, 223 students in two Arab countries, including 103 boys and 120 girls, are divided into two age groups (CP (5-7 years), CM2 (10-12 years). These children are, in the same way to tests of attention (dam of numbers), given to tests of simulated conduct, at different moments of the day: four times a day, on different days of the week: Sunday, Monday, Tuesday, Wednesday and Thursday. To study the duration of sleep in our subjects we used a sleep diary. It was measured by the nights of the week of the experiment (Saturday / Sunday, Sunday / Monday / Tuesday, Tuesday / Wednesday, Wednesday / Friday and Friday / Saturday). The results indicate that attention performance fluctuates differently in various times of day and the day of the week as well as among students in CP than CM2. In addition, nighttime sleep durations fluctuate during the week differently depending on the weekly schedule. These results complete the reflections on the good moments for reflection, and can highlight the prominence of age, gender, geographic background of students, these data differ according to the geographic background of students (middle Eastern countries: Iraq, United Arab Emirates, on the one hand, France, on the other) or in the schedules proposed

Full textA review of the main dealing with "social facilitation" (zajonc 1965) and "social loafing" (latane, williams & harkins, 1979) reveal that explanatory systems supposed to give one an account of the influence of others' presence on individual performances are based on an "extrinsic conception" of the relationships existing between social dimension and human function. This conception, which attributes to the social dimension an, therefore, to the others' presence, the status of an external source of variation, is examined, this has to be referred to recent studies (monteil, 1988,1991) which attest that previous social insertions, and, son individual social histoiry, play an important part in the cognitive management of current social conditions of learning. Theses studies, which allow us to envision a participation of the social dimension to the elaboration of cognitive machanisms and processes, also invite us to explore what could be the effects of experimental mobilization of categorizations and social merberships on individual cognitive performances. The findings of our 4 studies confirmed our expectations. They lead one to take into account the subject's categorizations and memberships as well as their condition of activation or mobilization in order to show the influence exerted by others over individual performances. As prevously displayed by montell, our results resist to expanatory systems used in the framework of facilitation and social loefing. Finally, these results permit us to consider individual cognitive productions as being partly ruled by activation or mobilization, in specific social insertions, of values or norms internalized by the subject during his history. Thus, this work emphasizes the legitimacy of a socio-cognitive orientation aiming at articulating social dynamics and cognitive dynamics
Helo, Andrea. "Scene exploration during development : influence of perceptual features and semantic context on visual attention." Thesis, Sorbonne Paris Cité, 2016. http://www.theses.fr/2016USPCB205/document.
Full textThis dissertation investigated developmental mechanism underlying scene exploration. The results showed that ambient and focal attention strategies emerge by 12 months of age. Saliency guided eye movements more in children younger than 6 years compared with older children. Additionally, objects that were semantically inconsistent with the scene context equally attracted the gaze in young children and adults. Children were, however, attracted faster to high salient than to low salient objects. High-producers looked longer to consistent objects than low-producers while both groups looked equally long to inconsistent objects. The N400 ERP component was more pronounced for inconsistent than for consistent scene-word pairs. Low-producers exhibited a later N400 effect over the right frontal recording sites while in high-producers the N400 effect was observed earlier over the left frontal sites. Our results suggest that eye movement control during scene viewing mature from infancy to childhood. Even though ambient and focal modes are present in early infancy, scene exploration is dominated by focal mode. Additionally, young children use scene context, similarly to adults, in guidance of their visual attention. However, during early stages of development saliency has a stronger effect on gaze allocation compared with adults. Visual attention was also influenced by linguistic skills in young children

Full textPrevious research ans clinical observations suggest a high incidence of autism spectrum disorders (ASD) in visually impaired children. A phenomena of developmental regression or stagnation « developmental setback » observed in the second year of life of visually impaired babies appears to predict the later occurrence of ASD. Relatively little research has explored the behavioural manifestations of very young visually impaired children before and around the apparition of developmental setback. For this retrospective study, home movies of blind children at the age of 12 months, 24 months and between 3 and 4 years, are analysed and behaviours of social communication are coded, to detect early signs of ASD. Films of blind children having later recieved a diagnosis of ASD are compared to films of blind children without ASD. The results indicate a lower frequency of certain social communication behaviours in blind children with ASD as early as 12 months old, with particular differences being observed in social engagement behaviours. Differences are also observed in the level of functional language from 24 months. Motor and language stereotyped behaviours are observed equally in the two groups until the age of 3 when these behaviours increase in the blind ASD children and decrease in the blind children without ASD. Divergences in the type of play are identified, sensory play being more frequent in the blind ASD children. Certain social rejection behaviours and sensory sensitivities are only observed in the blind ASD group. The results of this study contribute to a better understanding of early ASD signs in the blind, and improvements in the early screening of ASD in very young visually impaired children, as well as guiding early intervention programmes

Full textAttention can be defined as the act of focusing on something. We develop this cognitive function necessary to adjust our interactions with the world since birth.The general goal of this research is to understand the functioning of attentional processes through two questions: how attentional processes are developed in healthy children and how they are altered in children treated for a cerebellar tumor. This thesis specifically aims to study the dissociation between automatic and controlled processes of visual selective attention, firstly in normal cognitive development and secondly in their impairment in children treated for a cerebellar tumor. By incorporating in parallel a behavioral approach and an approach in functional imaging, this interdisciplinary work is at the crossroads of cognitive psychology, cognitive neuropsychology and cognitive neurosciences.This manuscript has two parts. The theory part is composed of three chapters: the functioning, the normal development and the deficits of attention in children treated for a cerebellar tumor. The experimental part includes two chapters. The first one concerns the attentional development in participants from seven years old to an adult age, with a behavioral approach using two experimental paradigms and an approach in functional imaging. The second chapter, with the help of this double approach, presents an alteration of attention in children treated for a posterior fossa tumor. The results showed on one side that automatic and controlled attentional processes were dissociated in their development at a behavioral and a functional level. And on the other side, the results revealed that although the automatic and controlled attentional processes are behaviorally preserved in children treated for a cerebellar tumor, they were subtended by a different modification of the functional network. Taken together these data suggest a distinct functioning of these processes in their normal development and their impairment in disease

Full textThe purpose of this study is to make a chrono-psychological assessment of the type of time organization applied in Algerian schools. Comparison was made between the single and double vacation types of school timing organization based on a sample of pupils aged between 11 and 12 years. The results of the study highlight the physiological and psychological impact of the two types of school vacation on Algerian pupils. Furthermore the daily and weekly attention levels of pupils in the double vacation type of organization indicate that this type of time organization is well suited for Algerian pupils who seem well adapted to their school timing. With regard to the behavior of the two children observed during the study it was found that those in the double vacation type were better adapted to daily school life compared to their peers in the single type of vacation. However during the week it is the pupils in the single vacation type who showed a better level of adaptation. The results also indicate that regardless of the type of time organization and the time of school entrance the subjects showed no troubles with regard to time of sleeping or awaking: Pupils from the two types of time organization slept more than the average time indicated by chrono-psychological research. However it was also shown that the brake taken tuesday afternoon by pupils from the double vacation type - unlike their peers in the single vacation type- had no positive effects, but the brake taken in the weekend by all pupils regardless of the type of vacation was useful for since it enabled them to take a rest and overcome their fatigue. With regard to extra- curricular school activities they clearly appear to be the same for all pupils

Full textChildren with Developmental Coordination Disorder (DCD) exhibit deep and persistent troubles in daily life activities requiring motor coordination. This thesis aims to characterize the trouble of these children both at a behavioural and an electrophysiological level. From a dynamic pattern perspective, we investigated whether the deficiency in motor coordination pertains to a general disorder in synchronization, and the extent to which the trouble is linked to attentional capacities. Twenty-four DCD children and 60 control children were asked to accomplish (1) a perceptivomotor task, (2) a bimanual task, and (3) a test assessing sustained attention. During these tasks, we recorded the EEG. Different tools of analysis were used (EEG coherence, power spectrum, event related potential) in order to characterize the neurophysiological correlates of such a synchronisation disorder

Full textDevelopmental dyslexia or reading difficulty is one of the most common problems that severely affect academic performance. It is displayed as a difficulty in learning to read despite conventional teaching, without being the direct result of any intellectual disadvantage or unfavourable environmental influence. It affects 4% to 8% of children. In this thesis work, we first compared effects of three remediation programs (Semiophony, modified speech and standard) on behavioral performances and on brain activations using functional MRI. The three different types of remediation elicited the same behavioral improvement. Moreover, they had a common effect upon brain activation changes. In the second part of this manuscript we studied pre-attentive auditory deficit in dyslexic children compared to control children. This research project is included in a European project called Neurodys. Mismatch Negativity elicited by different European vowels (French, Finnish, Hungarian and German) was compared in the two groups of subjects. Correlations between reading level and vowel treatment showed a strong support for allophonic perception mode in dyslexic children
