Title: The Assessment of the Impact of the Sports Aerobics on the Postural Stabilization of the girls aged 8 to 10 years Definition of the problem: This thesis deals with testing of the postural stabilization and also deals with detection of the occurrence of hypermobility in two groups of girls aged 8-10 years. The first group consist of girls that do sports aerobics and second group consist of girls that do not do any sport. Objectives: In the theoretical part I will devote a summary of findings on the development of postural security, with motor development and motor learning and also very briefly the hypermobility. The aim is to verify if the sports aerobics has a formative influence on postural stabilization of girls at a school age. I examine if the high training load at this early age leads to changes in postural motor skills in terms of its positive or negative influence. Furthermore, the research confirms the higher incidence of hypermobility among athletes. Methods: Selection of the research group on a voluntary basis and according to predetermined criteria. Practical testing of children assembled using two test batteries. Statistical data processing (Student's t-test, Spearman's correlation coefficient). Comparing the results between the two groups of girls. Results: Two test sets...

Le feedback auditif se définit comme un signal auditif qui contient de l'information sur un mouvement. Il a été montré que le feedback auditif peut guider le mouvement en temps réel, mais son influence sur l'apprentissage moteur est moins clair. Cette thèse a pour but d'examiner l'influence du feedback auditif sur l'apprentissage moteur, en se focalisant sur le contrôle temporel des mouvements. Premièrement, nous étudions l'apprentissage moteur chez les non-musiciens sains et montrons qu'ils bénéficient de l'information temporelle contenue dans le feedback auditif et qu'ils sont sensibles aux distorsions de cette information temporelle. Deuxièmement, nous appliquons ces connaissances à la réhabilitation de patients cérébro-lésés. Nous trouvons que ces patients améliorent leurs capacités de mouvement mais ne dépendent pas de la correspondance temporelle entre le mouvement et le son. Paradoxalement, ces patients ont même bénéficié des distorsions temporelles dans le feedback. Troisièmement, nous étudions les experts musicaux, car ils ont établi des liens particulièrement forts entre leur mouvement et le son. Nous développons de nouveaux outils d'analyse qui nous permettent de séparer les déviations temporelles en variation systématique et non-systématique. Le résultat principal est que ces experts sont devenus largement indépendants du feedback auditif. La proposition centrale de cette thèse est que le feedback auditif joue un rôle dans l'apprentissage moteur de la régularité, mais la façon dont le cerveau l'utilise dépend de la population étudiée. Ces résultats donnent une nouvelle perspective sur l'intégration audio-motrice et contribuent au développement de nouvelles approches pour l'apprentissage de la musique et la réhabilitation / Auditory feedback is an auditory signal that contains information about performed movement. Music performance is an excellent candidate to study its influence on motor actions, since the auditory result is the explicit goal of the movement. Indeed, auditory feedback can guide online motor actions, but its influence on motor learning has been investigated less. This thesis investigates the influence of auditory feedback in motor learning, focusing particularly on how we learn temporal control over movements. First, we investigate motor learning in non-musicians, finding that they benefit from temporal information supplied by the auditory signal and are sensitive to distortions of this temporal information. Second, we turn to stroke patients that are re-learning motor actions in a rehabilitation setting. Patients improved their movement capacities but did not depend on the time-locking between movements and the resulting auditory feedback. Surprisingly, they appear to benefit from distortions in feedback. Third, we investigate musical experts, who arguably have established strong links between movement and auditory feedback. We develop a novel analysis framework that allows us to segment timing into systematic and non-systematic variability. Our finding is that these experts have become largely independent of the auditory feedback. The main claim defended in this thesis is that auditory feedback can and does play a role in motor learning of regularity, but the way in which it is used varies qualitatively between different populations. These findings provide new insights into auditory-motor integration and are relevant for developing new perspectives on the role of music in training and rehabilitation settings

A iniciação esportiva tem sido foco de diversos estudos nas áreas das Ciências do Esporte e da Psicologia do Esporte. A aquisição de habilidades, como uma área específica, também tem concentrado esforços de diversos pesquisadores. A Análise do Comportamento aplicada a estes campos tem muito por oferecer. Estudos sobre comportamento verbal, especificamente, podem contribuir substancialmente para a solução de problemas na relação entre professores/ treinadores e iniciantes. Um procedimento, frequentemente utilizado e descrito na literatura específica é a auto-fala, que consiste em verbalizações emitidas para um falante, tendo ele mesmo como ouvinte. Ambientes esportivos costumam ser complexos, no que se refere à disponibilidade de estímulos, proporcionando dificuldades relacionadas à concentração. A auto-fala, como descrita e explicada na literatura, acaba tendo a função de auxiliar o atleta a selecionar estímulos relevantes para as tarefas esportivas, facilitando o estabelecimento de discriminações. O presente estudo investigou o efeito isolado de procedimentos de auto-fala sobre a aquisição de habilidades em modalidades esportivas simuladas, com sete adolescentes sem experiência prévia em treinamento com as modalidades e/ou com o equipamento. Foi utilizado o console de videogame Wii, no treinamento das habilidades de rebatida no beisebol, e lançamento da bola no boliche. Os dados obtidos sugeriram que os participantes, que utilizaram os procedimentos verbais, apresentaram desempenhos superiores, em comparação aos que não o fizeram. Também foi realizada uma comparação entre dois tipos de procedimentos de auto-fala: reforçada diferencialmente e instruída. Foram encontradas diferenças de desempenho, porém não tão significativas quanto às diferenças entre os participantes que se valeram dos procedimentos verbais e os que não o fizeram / The sport initiation has been the focus of several studies in the areas of Sports Science and Sports Psychology.

In the essay, "From Mimism to Music in the Child" (1935), Jousse, the French linguistic anthropologist, * describes the process whereby instinctive learning takes place and develops into cognitive motor skills in the Child; * traces the connections between the stages of learning and the skills acquired by the Child. These skills include gestural mimic imitation, drawing, listening, speaking, and musical expression; * makes specific recommendations about the process of teaching the Child; * relates the stages in the early learning processes in the Child to the development globally and universally of the anthropos; * demonstrates the relationship between Man and his fellows, both as individuals and as expression of cultural distinction, and between Man and the universe; * comments on the distinction between human and animal learning capacities; * explains the roles of key features in human expression; *explains aspects of cultural and linguistic change; * comments on cultural and linguistic change. In this research-essay, I am * attempting to clarify, in various degrees, all of the above: the learning issues receive more attention than do the rest; * attempting to identify the similarities and differences between the thinking and views on learning of Jousse with those particularly of Rudolf Laban, and incidentally of Montessori and Lenneberg; * demonstrating an 'Oral-Style text'. The Introduction to this research-essay summarises the thinking of Jousse and Laban. The Body of the study: * provides biographical information about Jousse and Laban; * explains the difficulties and problems encountered with the text of the essay "From Mimism to Music in the Child"; * comments on the nature and operation of Oral-Style texts and their cognitive and affective influence upon the reader; * contextualises and interprets the text of the essay, "From Mimism and Music in the Child". The Conclusion adds comments, and suggests areas for further study and investigation. / Thesis (M.A.)-University of Natal, 1995.

The changing nature of work and its competitive characteristics are global phenomena and are mainly fuelled by ongoing technological advancement. This creates unique challenges for talent attraction and the retention of high performing individuals. In addition, the global workforce is becoming more diverse due to demographic, societal and cultural changes and companies are placing greater demands on employee competency and performance. Managing the human factor as a strategic asset in organisations remains a primary challenge in securing a competitive advantage. The road construction industry in South Africa is no different. There is growing competition between civil engineering contractors to secure tenders and to maximise profitability. This is only possible with a sufficient and sustainable labour force. Valid selection processes are therefore required to ensure that the most productive individuals are selected for the most suitable jobs. Reliable and valid performance predictors will assist employers in making appropriate selection decisions. Selecting high performing individuals will support and enhance overall organisational performance. ix In this study the investigation focused on whether psychomotor ability and learning potential are statistically significant predictors of work performance - with specific reference to drivers and machine operators in a road construction company. A quantitative approach was followed to investigate the relationships between variables, or then the prediction of one dependent variable (driver and machine operator performance) by means of two independent variables (psychomotor ability and learning potential). Results from the study did not indicate any statistically significant relationships between the variables. Only scientifically validated assessment instruments were used in the study - which means the findings led to a renewed focus on the importance of performance measurement and the psychometric quality (reliability and validity) of performance data. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology)

In the present study aims to investigate whether the benefits generated by the typical practice self-control subjects are also found in individuals with motor impairment after stroke.The subjects, 26 adults of both sexes, with injury after stroke for at least 6 months, will be divided into two groups. A group of often self-controlled feedback (self) and a yoked group, which will receive feedback in a controlled externally, similar to a group subject to a self-controlled. The task of balance with demand, is to ride a pedal for some distance in the shortest possible time. All attempts to start with the foot contralateral to hemiparesis. A timer will be used to measure the movement time (MT), ie, the time needed to walk with the pedal to the starting line finish line. The research will consist of an acquisition phase, where participants will conduct 20 trials of practice, and a retention phase, 24 hours after the acquisition phase, in which four attempts to hold practice.The subjects of the group self, will be told they can use to support the upper limb support in attempts in which they find necessary.Yoked to subjects in the group, will be informed that in some trials should use the support and not others. The retention phase is performed without support in both groups. Before testing, subjects should be informed that the task at top speed / Estudos recentes sobre aprendizagem motora têm indicado a efetividade da prática que incorpora alguma forma de autocontrole na aprendizagem e na performance de uma tarefa motora (JANELLE, 1997; CHIVIACOWSKY & WULF, 2002). No presente estudo objetiva-se investigar se os benefícios gerados pela prática autocontrolada em sujeitos típicos também serão encontrados em sujeitos com comprometimento motor após acidente vascular encefálico (AVE). Os sujeitos, 26 adultos de ambos os sexos, com lesão pós AVE há pelo menos 6 meses, serão distribuídos em dois grupos. Um grupo com frequência de feedback autocontrolado (self) e um grupo que receberá feedback de forma externamente controlada (yoked), equiparados um a um aos sujeitos do grupo autocontrolado. A tarefa, com demanda de equilíbrio, consistirá em andar de pedalo por certa distância no menor espaço de tempo possível. Todas as tentativas iniciarão com o pé contralateral à hemiparesia. Um cronômetro será utilizado para medir o tempo de movimento (TM), ou seja, o tempo necessário para andar com o pedalo da linha de partida até a linha de chegada. A pesquisa constará de uma fase de aquisição, onde os participantes realizarão 20 tentativas de prática, e uma fase de retenção, 24 horas após a fase de aquisição, em que realizarão quatro tentativas de prática. Aos sujeitos do grupo self, será informado que poderão utilizar o suporte para apoio dos membros superiores nas tentativas em que acharem necessário. Aos sujeitos do grupo yoked, será informado que em algumas tentativas deverão utilizar o suporte e em outras não. A fase de retenção será realizada sem auxílio do suporte em ambos os grupos. Antes da realização do teste, os sujeitos serão informados que deverão realizar a tarefa na maior velocidade possível

Apprendre de nouvelles habiletés motrices est fondamental à l'expérience humaine et à l'exécution des activités quotidiennes. L'apprentissage moteur peut être défini comme un ensemble de processus associés à la pratique ou à l'expérience menant à la capacité d'exécuter une nouvelle habileté motrice. À l'origine de ces mécanismes d'apprentissage, un contrôle moteur précis et une intégration sensorimotrice adéquate sont essentiels. De plus, la capacité d'identifier une séquence dans des évènements sériels et de reproduire avec précision la série de mouvements détectés est également importante en ce qui concerne l'apprentissage des séquences motrices présentes dans de nombreux comportements humains. Si l'un de ces processus élémentaires est compromis par une pathologie, on peut s'attendre à observer des difficultés à apprendre différentes habiletés motrices. Les études qui composent la présente thèse avaient pour objectif principal de caractériser les capacités d'apprentissage moteur dans deux populations cliniques présentant une anomalie sensorielle ou motrice avec la tâche de temps de réaction sérielle (TTRS). Dans l'article 1, les conséquences de la surdité sur l'apprentissage moteur ont été étudiées. Peu d'études ont examiné les capacités motrices chez les sourds profonds et ces quelques études ont suggéré la présence de déficits en dextérité manuelle et des retards dans la production de mouvements. Avant la publication de cet article, la capacité d'apprendre des séquences motrices complexes n'avait pas été explorée dans une population adulte sourde. L'apprentissage non-spécifique et spécifique à la séquence à la TTRS a été analysé en fonction des caractéristiques individuelles liées à la perte auditive. Les résultats ont révélé des différences significatives entre les groupes dans l'apprentissage spécifique à la séquence, les sujets sourds étant moins efficaces que les contrôles à acquérir les connaissances spécifiques à la séquence. Nous avons interprété les résultats à la lumière de la plasticité intermodale et de l'hypothèse d'échafaudage auditif. Dans l'article 2, l'apprentissage moteur, le transfert intermanuel d'une habileté motrice nouvellement acquise et la modulation du débordement moteur électrophysiologique (mouvements miroirs physiologiques; MMp) ont été évalués dans une grande famille de quatre générations avec des mutations du gène Deleted in Colorectal Cancer (DCC) et des mouvements miroirs congénitaux (MMC). Les MMC sont des contractions musculaires involontaires de l'autre côté du corps survenant lors d'un mouvement unilatéral volontaire. Ils ont été associés à une mutation dans le gène DCC, entraînant des voies cortico-spinales anormales et une inhibition interhémisphérique réduite (IIH). Comparativement aux membres de la famille sans MMC et aux contrôles sains non-apparentés, les MMp des individus avec MMC ont été significativement augmentés après l'exécution de la TTRS. L'apprentissage moteur et le transfert intermanuel ne différaient pas entre les groupes. Cependant, lorsque les participants avec la mutation DCC, avec ou sans MMC, étaient spécifiquement comparés aux participants sans la mutation DCC, l'apprentissage non-spécifique d'une séquence motrice était significativement réduit chez les personnes atteintes de la mutation DCC. Ces données suggèrent qu'une augmentation de l'activité miroir physiologique chez les patients atteints de MMC est associée à une réduction de l'IIH. De plus, les diminutions d'apprentissage moteur non-spécifique chez les porteurs de la mutation DCC pourraient être liés aux altérations de l'activité cérébelleuse et de la connectivité rapportées antérieurement. En résumé, les études comprises dans la présente thèse ont approfondi nos connaissances des capacités d'apprentissage moteur dans les contextes de déficits sensoriels ou moteurs. / Learning new motor skills is essential to the human experience and to the performance of everyday activities. Motor learning can be defined as a set of processes associated with practice or experience leading to the ability to skillfully perform a new motor skill. At the root of these learning mechanisms, precise motor control and adequate sensorimotor integration are critical. Additionally, the ability to identify a sequence in serial events and accurately reproduce the series of detected movements is also important with regards to learning motor sequences that are present in many human behaviors. If any of these fundamental processes are compromised by any pathology, one can expect to observe difficulties in learning different motor skills. The studies that compose the present thesis had as a main objective to characterize the motor learning abilities in two clinical populations presenting a sensory or motor abnormality with the serial reaction time task (SRTT). In article 1, the consequences of hearing impairment on motor learning were investigated. Few studies have examined motor capacities in the profoundly deaf and these studies have suggested the presence of deficits in manual dexterity and delays in movement production. Before the publication of this article, the ability to learn complex sequential motor patterns had not been explored in a deaf adult population. Non-specific and sequence-specific learning on the SRTT were analyzed in relation to individual features related to the hearing loss. The results revealed significant differences between groups in sequence-specific learning, with deaf subjects being less efficient than controls in acquiring sequence-specific knowledge. We interpreted the results in light of cross-modal plasticity and the auditory scaffolding hypothesis. In article 2, motor learning, intermanual transfer of a newly acquired motor skill and activity-dependent modulation of electrophysiological motor overflow (physiological mirror movements; pMM) were assessed in a large, four-generational family with a Deleted in Colorectal Cancer (DCC) gene mutation and congenital mirror movements (CMM). CMM are involuntary muscle contractions in the opposite side of the body occurring during voluntary unilateral movement. They have been associated with a frameshift mutation in the DCC gene, resulting in abnormal corticospinal tracts and reduced interhemispheric inhibition (IHI). Compared with family members without CMM and unrelated healthy controls, pMM were significantly increased in CMM individuals following execution of the SRTT. Motor learning and intermanual transfer did not differ between groups. However, when participants with the DCC mutation, with or without CMM, were compared with participants without the DCC mutation, non-specific learning of a motor sequence was significantly reduced in individuals with the DCC mutation. These data suggest that increased physiological mirroring in CMM patients is associated with reduced IHI. Furthermore, impairments in non-specific motor learning in DCC mutation carriers may be related to the reported alterations in cerebellar activity and connectivity. In summary, the studies comprised in the present thesis significantly increase our knowledge of motor learning abilities in the contexts of sensory or motor deficits.

本研究は，視聴する映像を学習者自身で選択させることによる運動学習効果を検討する事が目的であった．本研究の結果，学習者自身が映像を選択する事で，実験者によって選ばれた映像を視聴した場合と比較して，映像と学習者の運動イメージとの認知的な一致度を高めた．さらに，観察角度や選択の方法の違いが運動学習の向上に寄与する事を明らかにした．これらの知見は，運動指導や体育授業における映像の視聴方法や選び方といった提供方法の提案に繋がるだろう． / This study aimed to examine the motor learning effects of allowing learners to choose their own footage to watch. As a result, this study showed that the learner's chosen footage enhanced the cognitive consistency between the video and the learner's motor imagery, compared to the case in which the experimenter chosen video was shown. Furthermore, we found that differences in observational angle and the method of choice contributed to the improvement of motor learning. These findings would be led to propose a method of providing the video, such as how to watch them and how to choose them on a motor instruction and physical education. / 博士(スポーツ健康科学) / Doctor of Philosophy in Health and Sports Science / 同志社大学 / Doshisha University
