Cognitive Abilities and their Influence on Speech-In-Noise Information Processing : a Study on Different Kinds of Speech Support and Their Relation to the Human Cognition / Kognitiva förmågor och deras influens på informationsbearbetning av tal-i-brus : en studie på olika typer av talstöd och deras relation till mänsklig kognition

Sjöström, Elin January 2017 (has links)
In this paper, top-down and bottom-up processing were studied regarding their effect on speech-in-noise. Three cognitive functions were also studied (divided attention, executive functioning, and semantic comprehension), and the effect they have on the speech processing and on each other. The research questions asked were if a difference in speech-in noise perception can be observed regarding the different levels of top-down and bottom-up support, if speech-in-noise is related to any of the researched cognitive abilities, and if there exists any correlation between these abilities. The method is a within-subject experimental design, consisting of four different tests: PASAT, to measure attention, LIT, to measure semantic comprehension, TMT, to measure executive functioning and SIN, to measure speech-in noise. The results showed a significant difference between top-down and bottom-up processing, a significant difference between top-down processing in decreasing and increasing conditions could also be seen. A negative correlation between the benefit of top-down support and the semantic comprehension task was found. Regarding the cognitive abilities a few correlations were found; the semantic comprehension task had a positive correlation to both the central executive task and the attentional task, the attentional task had a negative correlation to the central executive task, and both of the central executive subtasks had a positive correlation to each other. Most of the findings were expected, built on earlier cognitive hearing theories and studies.

Relação entre funções cognitivas e perdas adquiridas na visão de cores de pacientes com esclerose múltipla tipo remitente recorrente / Relationship between cognitive functions and acquired color vision loss in patients with relapsing-remitting type of multiple sclerosis

Rosaní Aparecida Antunes Teixeira 12 September 2012 (has links)
A Esclerose Múltipla (EM) é uma doença inflamatória autoimune caracterizada por desmielinização e degeneração do sistema nervoso central (SNC) duas a três vezes mais frequente em mulheres. A etiologia da EM é dividida em dois subtipos principais: o tipo remitente-recorrente (EMRR) mais comum, caracterizado por dois ou mais episódios de agravamento dos sintomas que envolvem diferentes locais do SNC, separados por pelo menos 1 mês e remisão dos sintomas e o tipo progressivo é a forma menos comum, caracterizada por um contínuo agravamento dos sintomas desde o início geralmente sem recaídas claras ou remissões. A presente pesquisa teve por objetivo avaliar o comprometimento da visão de cores e de sua relação com perdas de atenção, memória visual imediata, memória visual tardia, memória operacional e funções executivas dos portadores de esclerose múltipla tipo remitente recorrente. Método: participaram 41 pacientes com esclerose múltipla de idades entre 20 e 58 anos (35,4±12,2) e 37 controles com idade (34,7±12,1) e escolaridade semelhante. A discriminação de cores foi avaliada com o Cambridge Colour Test (CCT) e a avaliação de funções neuropsicológicas foram utilizados subtestes da bateria Cambridge Neuropsychological Testing Automated Battery (CANTAB) - Pattern Recognition Memory, Spatial Span, Spatial Recognition Memory, Information Sampling Task, Stop Signal Task e Rapid Information Processing; Escalas de Depressão e Ansiedade de Beck e Escala de Determinação Funcional da Qualidade de vida (DEFU). Resultados: A visão de cores está prejudicada de forma difusa em 24% dos pacientes com esclerose múltipla, tanto em pacientes com histórico de neurite óptica quando em pacientes que não tiveram neurite óptica. Na parte cognitiva, os pacientes demonstraram lentidão em executar as tarefas, comprometimento na atenção, na memória visual de curto e longo prazo, na memória operacional, na memória visuoespacial, além de lentidão no processamento de informações. Há uma relação entre alterações na visão de cores e alterações de memória visual somente em testes em que os estímulos são complexos e com inúmeros detalhes / Multiple sclerosis (MS) is an autoimmune inflammatory disease characterized by demyelination and central nervous system (CNS) degeneration. It is two times more frequent in women. It can be presented in two subtypes: the relapsing-remitting (RR), most common type, characterized by two or more episodes of focal disorders in different sites of the CNS, and remission of the symptoms; and the progressive subtype, less common, characterized by a continuous worsening of the symptoms, since the beginning, usually with no remissions. The present research evaluated color vision impairment and its relationship to attention loss, short-term memory, long-term memory, working memory and executive function in patients with the relapsing-remitting MS type. Methods: 41 patients with multiple sclerosis (20 to 58 years, 35.4 ± 12.2 in average) and 37 controls matched to age (34.7 ± 12.1 in average) and years of education participated of the study. Color vision was tested using the Cambridge Colour Test (CCT) and the neuropsychological assessment was performed using tests of the Cambridge Neuropsychological Testing Automated Battery (CANTAB) - Pattern Recognition Memory, Spatial Span, Spatial Recognition Memory, Information Sampling Task, Stop Signal Task, Rapid Information Processing the Beck Depression and Anxiety Inventories and the Functional Assessment of Multiple Sclerosis quality of life instrument. Results: Color vision was diffusely impaired in 24% of the MS patients, with or with no history of optic neuritis. Patients also showed a delay during the tasks execution, impairment in attention, short and long-term visual memory and working memory, and slowness in the information processing. There was a relationship between color vision loss and visual memory impairment, but only in tests with complex and highly detailed stimuli

Problematika reliability a validity u dynamické diagnostiky / Reliability and Validity Issues of the Dynamic Assessment

Holeyšovská, Kateřina January 2018 (has links)
(in English): This thesis introduces the issue of reliability and validity of the dynamic assessment methods. In the theoretical part, the author briefly presents specifics of the dynamic assessment and various ways of verifying reliability and validity in the context of dynamic assessment. The text then summarizes ways of verifying reliability and validity for specific methods of the dynamic assessment based on experience from mostly foreign studies. The empirical part of the thesis aims to examine the relationship between the outputs of the ACFS method and characteristics of the assessors and subsequently to propose an optimal approach to the examination of the dynamic assessment methods. The results showed that the assessor was a statistically significant factor to the magnitude of the change in all ACFS scales. However, a more detailed analysis showed that the difference between the assessors varied across subtests. The qualitative analysis did not signify any relevance of specific characteristics to the differences between the assessors.

Diagnostika pozornosti u dětí v předškolním a mladším školním věku / Attention Assessment of Children at Preschool Age and Early School Age

Šnoblová, Vladěna January 2017 (has links)
Attention is one of the key competencies which has to be adequately developed in preschool children to support their good school adaptation and acceptation of school demands. This work describes current approaches to assessment of attention and related cognitive functions in children at preschool and early school years. On the basis of the methods which are accessible we introduce a new assessment tool, which could serve as screening of attention and other necessary competencies of children aged 5-7 years. The empirical part of this work shows results of a validization study of our method (Coloured trail making test for children), and its reliability the tool. Results proved strong correlations among our method and three other assessment tools from larger batteries of tests (Woodcock - Johnson Tests of Cognitive Abilities, IDS and CAS II). However, the outcomes of the tests are also different enough to conclude that each of four methods which we used can be important in the process of attention assessment in preschool children; and each of these methods can bring valid information about children's abilities. The work also includes normative data for Coloured trail making test for children, which can be used as a screening tool to detect minor difficulties of children's attention or it can help to...

Aktivizace seniorů jako odborná profese / Activation of Older People as a Professional Qualification

Zaworová, Neli January 2021 (has links)
The "Activation of Older People as a Professional Qualification" diploma thesis deals with the activation of older people and with the professionalization and professionalism of activation staff as professional workers. The thesis also focuses on the designing of activation methods as a professional tool that is to be beneficial to any pre-defined objectives of the activation and also successfully finalized. A key element in the process is the emphasis placed on the professional knowledge of activation, its principles, the possibility of designing the procedures from a holistic point of view, and the subsequent planning of activation collectively, with respect to a team, as well as individually, in a manner that is tailored to the client. In this thesis, I define the profession of an activation worker as highly professional, requiring an active dialogue between the activation worker as the guarantor of activation and the activated, as a person who needs to achieve predetermined goals through activation. This work also addresses the demographic development of the population in the Czech Republic (as a factor which confirms the need to professionally elevate this profession). It also defines the health, psychological and social aspects of old age in practice. However, this thesis focuses in...

Les effets aigus de l’exercice sur la réponse cérébrovasculaire et la performance cognitive chez des personnes coronariennes stables

Bérubé, Béatrice 08 1900 (has links)
Les patients coronariens (PC) sont plus à risque de présenter des déficits cognitifs et certains types démence. Les fonctions cognitives des PC ont été étudiées au repos, mais jamais au cours d’une séance d’exercice aigu. L’exercice aigu à haute intensité peut affecter négativement la performance cognitive chez des personnes saines. Bien que les PC soient plus à risque de dysfonctions cérébrales et cardiovasculaires, cette relation n’a jamais été étudiée au sein de cette population clinique et peut permettre de mieux comprendre l’axe coeur-cerveau. Il était postulé que la performance cognitive sera affectée par l’exercice à haute intensité due à une diminution de l’apport en oxygène seulement chez les patients coronariens. Trente-huit PC et 16 participants sains ont été recrutés. Les participants ont complété les mesures suivantes : (1) des tests neuropsychologiques et une familiarisation à la tâche de Stroop modifiée informatisée (2) un test mesurant la consommation d’oxygène jusqu’au pic de l’effort (VO2pic) et (3) la tâche de Stroop à 30% et 70% de leur puissance maximale atteinte au VO2pic tout en pédalant sur un ergomètre. L’oxygénation cérébrale a été mesurée grâce à la spectroscopie proche infrarouge. Les résultats ont démontré que la performance cognitive est restée stable entre les deux intensités pour les deux groupes. Chez les PC, le volume sanguin cérébral était affecté négativement par l’effort physique à haute intensité comparativement à l’intensité modérée et aux participants sains. La maladie coronarienne affecte négativement l’oxygénation cérébrale pendant un effort à haute intensité. D’autres études sont nécessaires afin de déterminer si un test cognitif administré pendant un effort physique pourrait permettre d’identifier les patients coronariens à risque de déclin cognitif. / Coronary heart disease (CHD) patients are at higher risk for developing cognitive deficits and certain types of dementia. The cognitive functions of coronary patients have been studied at rest, but never during an acute exercise session. Acute high intensity exercise negatively affects cognitive performance in healthy people. Although coronary patients are at higher risk of cerebral and cardiovascular dysfunction, this relationship has never been studied in this clinical population and could help better understanding of the heart-brain axis. The aim of this study was to measure the effects of an acute exercise at two different intensities on cognitive performance and cerebrovascular response in CHD patients. It was hypothesized that higher exercise intensity will impair executive performance and cerebrovascular response only in CHD patients. Thirty-eight CHD patients and 16 healthy controls completed neuropsychological assessments, maximal cardiopulmonary exercise testing and two exercise bouts at 30% and 70% of their individualized maximum capacity on an ergocycle while performing a cognitive test including non-executive and executive conditions. Cerebral oxygenation and perfusion were measured during both intensities in all participants with near-infrared spectroscopy. The results demonstrated that the cognitive performance remained stable between the two intensities for both groups. In CHD patients only, cerebral blood volume was negatively affected by high intensity exercise compared with moderate intensity. Coronary heart disease negatively affects cerebral oxygenation during high intensity exercise. Further studies are needed to determine whether a cognitive test administered during physical exertion could identify coronary patients at risk of cognitive decline.

Guidelines for the improvement of reading comprehension skills with reference to the learning disabled secondary school pupil

Lategan, Irene Anne Stewart 11 1900 (has links)
In the secondary school situation, a pupil needs to read to learn, therefore it is imperative to comprehend what is read. Reading comprehension is one of the two functions of reading and it is dependent on the abilities of the reader, the reader's interpretation of the text and the context in which the text is read. In examining reader characteristics, it is evident that it is very difficult for learning disabled pupils with a reading comprehension deficit to comprehend successfully. Their · unique problems can be exacerbated by such external factors as text components and the context in which the reading takes place. Reading comprehension has been instructed to learning disabled secondary school pupils using reading methods and strategies, to facilitate reading comprehension. From this practical experience and the literature studied, guidelines have been formulated for teachers to use to improve the reading comprehension skills of learning disabled secondary school pupils. / Educational Studies / M.

Le profil des récidivistes en matière de conduite avec capacités affaiblies par l’alcool : une étude des caractéristiques neuropsychologiques et psychologiques des contrevenants selon leur sexe

Fillion-Bilodeau, Sarah 06 1900 (has links)
Durant les dernières décennies, les différences intersexes en matière de conduite avec les capacités affaiblies par l’alcool (CCAA) ont suscité l’attention, alors que le comportement est en augmentation chez les femmes tandis qu’il diminue chez les hommes. Les données suggèrent que, chez les femmes, la CCAA s’associe à des caractéristiques psychologiques différentes de celles qui se retrouvent chez les contrevenants masculins (c.-à-d. davantage de problèmes liés à l’alcool et aux drogues et de psychopathologies, mais moins de recherche de sensations et de comportements délinquants). Malgré ce profil différentiel, les femmes contrevenantes de la CCAA demeurent une population hautement méconnue, particulièrement en ce qui a trait au profil des récidivistes. Alors que chez les hommes, des données émergentes indiquent que des limitations cognitives sont présentes chez les récidivistes et qu’elles constituent potentiellement un mécanisme sous-jacent au comportement, le profil cognitif des femmes récidivistes demeure inexploré. Des données exploratoires obtenues chez les contrevenantes et la documentation de champs de recherche connexes suggèrent que les femmes se distinguent notamment en ce qui concerne leur fonctionnement exécutif qui pourrait être préservé, alors que leur fonctionnement visuospatial serait déficitaire en comparaison de leurs vis-à-vis masculins. L’objectif de la présente thèse est d’approfondir les connaissances sur les caractéristiques des femmes récidivistes, ce qui permettra de mieux comprendre l’hétérogénéité de cette population et de générer des hypothèses au regard des mécanismes cognitifs sous-jacents à la répétition du comportement de CCAA. Plus spécifiquement, la thèse a pour objectif premier d’étudier les différences entre les sexes en matière de fonctionnement visuospatial et de mémoire visuelle, d’attention et de fonctionnement exécutif (c.-à-d. flexibilité cognitive, abstraction, inhibition). L’objectif secondaire consiste à comparer ces contrevenants au regard de leurs caractéristiques psychologiques (problèmes liés à l’alcool et aux drogues, impulsivité, recherche de sensations, traits antisociaux, anxiété et dépression). L’hypothèse examinée soutient que les femmes et les hommes récidivistes de la CCAA performent moins bien que les femmes et les hommes non-contrevenants en termes de fonctionnement visuospatial, attentionnel et exécutif. En outre, il est attendu que les femmes récidivistes présentent des performances inférieures à celles des hommes récidivistes en ce qui a trait aux fonctions visuospatiales. Par ailleurs, l’hypothèse prévoit que les hommes récidivistes aient des performances inférieures à celles des femmes récidivistes sur le plan exécutif et attentionnel. En matière de caractéristiques psychologiques, il est attendu que les femmes et les hommes récidivistes présentent significativement plus de problèmes liés à l’alcool et aux drogues, d’impulsivité, de recherche de sensations et d’indices de psychopathologies (tendance antisociale, dépression, anxiété) que les non-contrevenants. En outre, il est attendu que les femmes récidivistes présentent plus de problèmes liés à l’alcool et aux drogues et d’indices de dépression et d’anxiété que les hommes récidivistes. Enfin, il est attendu que les hommes récidivistes présentent significativement plus d’impulsivité, de recherche de sensations et de traits antisociaux que les femmes récidivistes. Ces hypothèses se confirment partiellement, alors que les hommes récidivistes (n = 39) présentent des performances inférieures à celles des hommes non-contrevenants (n = 20) et des femmes récidivistes (n = 20) sur le plan attentionnel et exécutifs. Toutefois, les femmes récidivistes ne se distinguent pas des femmes non-contrevenantes (n = 20) en matière de fonctionnement neuropsychologique. En ce qui a trait aux caractéristiques psychologiques, les résultats soutiennent partiellement les hypothèses. La discussion met en lumière que les femmes et des hommes récidivistes présentent des caractéristiques similaires, hormis en ce qui a trait au fonctionnement attentionnel et exécutif qui semble jouer un rôle dans la récidive au masculin, alors que cela n’apparaît pas être le cas chez les femmes chez qui le comportement pourrait être davantage situationnel. La nécessité que des études futures soient réalisées au moyen de devis expérimentaux, de même que les difficultés inhérentes au recrutement des femmes récidivistes sont discutées. / During the past decade, female driving while impaired by alcohol (DWIA) have gathered more attention as DWIA is increasing in females while decreasing in males. Data suggest that DWIA risk in females is associated with distinct psychological characteristics from those of male offenders (i.e. more alcohol and drug-related problems, and psychopathology, while less sensation seeking and delinquency). Despite this differential profile, female DWIA offenders remain a highly unknown population, especially regarding recidivism. In addition, growing data, mostly based on male offenders, support the idea that cognitive limitations are present in recidivists and represent a potential underlying mechanism to their behavior. Exploratory data collected in female offenders and data from other germane research fields suggest that female recidivists are cognitively distinct, especially in terms of executive functioning that could be relatively spared while their visuospatial functioning would be more impaired in comparison of male offenders. The objective of this dissertation is to enhance knowledge on female recidivist’s characteristics. This will allow a better comprehension of the heterogeneity of DWIA recidivist’s population and generate hypotheses concerning potential mechanisms that underlie their repetitive DWIA behavior. The thesis is especially targeting neuropsychological and psychological characteristics of female recidivists. More specifically, the study’s first aim is to examine DWIA recidivists sex differences regarding visuospatial functioning, attentional and executive functions (i.e. cognitive flexibility, abstraction, inhibition). The secondary objective is to compare offenders on psychological characteristics (alcohol and drug use, impulsivity, sensation seeking, anxiety, depression and antisocial tendencies). It is hypothesized that female and male DWIA recidivists would present a lower performance than their respective non-offender counterparts in terms of visuospatial, attentional and executive functions. In addition, it is expected that female recidivists would present a lower visuospatial performance than male recidivists. It is also hypothesized that male recidivists would exhibit lower attentional and executive performances than female recidivists. Regarding psychological characteristics, it is expected that recidivists would present more alcohol and drug-related problems, impulsivity, sensations seeking and psychopathology (antisocial tendencies, depression, anxiety) than non-offenders and that female recidivists would present more alcohol and drug-related problems, depression and anxiety than male recidivists. Finally, hypotheses suggest that male recidivists would present more impulsivity, sensations seeking and antisocial tendencies than female recidivists. These hypotheses are partially supported as male recidivists (n = 39) present lower attentional and executive performances than male non-offenders (n = 20) and female recidivists (n = 20). However, female recidivists do not significantly differ from female non-offenders (n = 20) in terms of neuropsychological functioning. In regard to psychological characteristics, results partially support hypotheses. The discussion highlights female and male similar characteristics except for attentional and executive mechanisms that seem to play a role in male recidivism, while it is apparently not the case in female recidivists whose behavior could be more situational. The need for further studies with experimental design as well as difficulty in female recruitment are discussed.

Zprostředkované učení - významný faktor pomoci sociálně znevýhodněným žákům (v procesu učení) / Mediated training as a possibility for socially disadvantaged students

Škopková, Pavla January 2015 (has links)
This Master thesis aims to solve the question of developmentally-creative possibilities in the schooling process. This question is contextualized education of socially disadvantaged pupils. Because in shaping the learning competencies, this area is not developed enough and specific methods are somewhat rigid, it will be introduced one of the option how to to develop learning skills and abilities of the pupils , and which are in the teaching competencies deemed as essential. In this context will be introduced stimulatory and intervention program of Instrumental Enrichment as a concrete form of execution of Mediated learning and also as an effort of perspective innovation of curriculum. With the intention to point out the limitless possibilities of developing pupil's learning potential, the text focuses on the theoretical and conceptual bases, which constitute the entire program. The program is the instrumental set of tools that lead to the activation of cognitive structures and their subsequent enrichment. Therefore, except the theoretical foundations are also presented cognitive strategies metacognitive training that simplify cognitive modifiability, and that lead to the development of pupils' learning potential.
