The aim of this dissertation was to investigate whether improving metacomprehension accuracy via the monitoring process impacted learning strategy selection implemented by the control process so that comprehension was also improved. A new paradigm—the multi trial metacomprehension paradigm—was introduced to investigate this aim. Participants studied a text using an effective or ineffective learning strategy, made metacomprehension predictions about their future comprehension, and took a comprehension test; there were three trials of this procedure. The goal was to determine whether metacomprehension accuracy improved—leading to improved comprehension accuracy—for the third trial. Experiment 1 tested whether metacomprehension accuracy improved across multiple trials when compared against single trials. Although no difference in metacomprehension accuracy between multiple and single trial conditions was found, comprehension accuracy did improve with multiple trials. However, for a subset of participants whose metacomprehension accuracy across trials did improve, their comprehension accuracy also improved. Although there was no effect of learning strategy on either metacomprehension accuracy or comprehension accuracy overall, the effective learning strategy produced the highest metacomprehension accuracy on the first trial, leaving no room for improvement at later trials. Metacomprehension accuracy only improved when using the ineffective learning strategy if it was used on multiple trials, but never to the same degree as when using an effective learning strategy. Experiment 2 tested whether improved metacomprehension accuracy affected the control process of learning strategy selection by allowing participants to select which learning strategy to use during the third trial. Participants overwhelmingly selected the ineffective learning strategy, even in case in which metacomprehension accuracy improved across trials. This finding calls into question the theory that improved monitoring accuracy informing the meta level leads to better implementation of control process on the object level. However, while metacomprehension accuracy might be necessary to improve comprehension accuracy—and to result in selection of effective learning strategies toward that end—it might not be sufficient. Students should not just be told to use an effective learning strategy; they should also be taught how to use cues during the monitoring process that are diagnostic of future comprehension.

Calibrated Judgments of Learning (CJOL) represent the degree to which students' judgments of learning (JOL) relate to their actual learning. Although a substantial amount of research has been conducted on calibration and JOL in various domains of psychology, only a growing number of studies have begun to address the use of CJOL in applied educational settings. This study investigated the use of CJOL in university developmental math courses. Study participants included 185 men and 100 women with ages ranging from 18 to 61 years (M = 23.48, SD = 5.95). Study results indicate that these developmental math students were fairly accurate in their perceptions of their math performance. When inaccurate, students most commonly under estimated their performance. Students' accuracy was also greatly influenced by the difficulty of math questions on the tests. High performing students were consistently more accurate than lower performing students. Over the course of the study, students received feedback on their accuracy in an attempt to facilitate improved accuracy. Results indicated that students' accuracy decreased with time; likely this was due to the increase in the difficulty of math questions on each test.

Within the self-regulation is the metacognitive monitoring, the ability with which the individual follows and evaluates their own cognition. The present study was divided into two studies, both aimed to investigate the metacognitive monitoring of illiterate adults using the metacognitive judgement, a measure of the metacognitive monitoring, in cognitive tasks that evaluate the general factor of intelligence, processing speed and short-term memory. The relation between the real performance and the estimated performance was also investigated, including in which cognitive task the real performance related more to the estimated performance. In addition, we investigated which type of judgment model – the only difference between the two studies – was the most accurate. The participants of Study (1) included 34 functional or fully illiterate adults, from both genders, and age between 40 and 60 years old; and participants of Study (2) included 15 functional or fully illiterate adults, from both genders, and age between 20 and 74 years old. The instruments utilized were: Initial Interview, R-1 Test and subtests Digit Symbol-Coding, Symbol Search and Digit Span from the Wechsler Adult Intelligence Scale III (WAIS III), Judgment Register from 0 to 10, Judgement Register from 0 to 100 and Judgement Register with the use of a metric object. Results indicated that the real performance of the subjects, in both studies, were lower when compared to subjects with a greater level of education, and, according to the Pearson product-moment correlation coefficient, there was a significant correlation between the real performance and the estimated performance in the subtest Digit Symbol-Coding in Study 1, and significant correlation between real and estimated performance in the subtests Digit Symbol-Coding, Digit Span and Symbol Search in Study 2. In addition, results indicated that the judgment made with a metric object presented he most accurate measures. / A autorregulação refere-se aos pensamentos, sentimentos e ações que são planejados e ciclicamente adaptados para o alcance dos objetivos traçados pelo indivíduo. Dentro dessa totalidade, encontra-se o monitoramento metacognitivo, que é a habilidade pela qual o sujeito “acompanha” e avalia sua própria cognição. Foram realizados dois estudos, ambos com o objetivo investigar o monitoramento de adultos analfabetos, por meio do julgamento, entendido como uma medida do monitoramento metacognitivo, sobre o desempenho em tarefas cognitivas que avaliam o fator geral de inteligência, a velocidade de processamento e a memória de curto prazo. Também foi investigada a existência de diferenças nas relações entre desempenhos reais e estimados e em quais tarefas cognitivas o desempenho real mais se relaciona ao desempenho estimado. Além disso, investigou-se qual o modelo de registro de julgamento foi o mais acurado, sendo o tipo de modelo utilizado a única diferença entre os estudos. Participaram do Estudo (1) 34 analfabetos funcionais ou absolutos, de ambos os gêneros e com idade entre 40 e 60 anos, e, no Estudo (2), 15 analfabetos funcionais ou absolutos, de ambos os gêneros e com idade entre 20 e 74 anos. Os materiais utilizados para a coleta de dados foram: Entrevista Inicial (EI), Teste R-1 e os subtestes Código, Procurar Símbolos e Dígitos da Escala Wechsler de Inteligência para Adultos III (WAIS III), Registro de Julgamentos de 0 a 10, Registro de Julgamentos de 0 a 100 e Registro de Julgamentos a partir de um objeto de medida. Os resultados indicaram que, em ambos os estudos, os escores reais dos participantes foram mais baixos quando comparados com sujeitos de maior escolaridade das amostras normativas dos instrumentos. A partir das correlações de Pearson, observou-se no Estudo 1 uma correlação significativa entre o desempenho real e o julgamento do desempenho no subteste Códigos; e, no Estudo 2, correlações significativas entre o desempenho real e o julgamento de desempenho nos subtestes Códigos, Dígitos e Procurar Símbolos. Ainda, os resultados indicaram que o julgamento de desempenho a partir de um objeto de medida foi o que apresentou as medidas mais acuradas.

Tracking the identity of occluded objects requires binding an object’s features to its location to represent exactly which objects are located where, relying heavily on capacity-limited visual working memory. This dissertation aims to examine the capacity and stability of object working memory, and the complexity and fidelity of object working memory representations, in toddlers and young children. A series of four experiments used a novel task to examine 28- to 40-month-old toddlers’ and 5- to 6-year-old children’s visual working memory recall of specific objects in specific locations. I predicted capacity limits would vary with age, presentation/occlusion type, and complexity, and that older children would be able to monitor these limits successfully. Children observed arrays of featurally-distinct objects that were hidden from view either simultaneously (Chapter 2, Experiment 1 and Chapter 3, Experiments 1 & 2) or sequentially (Chapter 2, Experiment 2) and were asked to recall an object’s location. When objects were hidden simultaneously, toddlers showed a capacity of 3 feature-location bindings (Chapter 2, Experiment 1) and 5- to 6-year-old children showed a capacity of 4 feature-location bindings (Chapter 3, Experiment 1), and both showed capacity development, supporting the hypotheses. When objects were hidden sequentially, toddlers’ performance was impacted by whether they had the easier (set size 2) or harder (set size 3) block first, suggesting the structure of the task may have influenced how children divided attention between maintaining and encoding of representations in working memory. Additionally, in Chapter 3, the number of feature bindings that children had to maintain was varied. Children could remember more single-feature objects than multi-feature objects (limit of 4 vs. 3, respectively), suggesting that binding additional features to a representation taxes cognitive resources, as hypothesized. Finally, the study in Chapter 3 explored children’s ability to monitor the fidelity of their visual working memories by asking them to gauge their confidence by placing bets with tangible, at-risk resources. Children modulated their bets appropriately, betting more after providing correct answers and fewer after incorrect answers, as hypothesized. Together, these data help to inform our understanding of visual working memory for feature-location bound objects across early development.

Studies in the field have produced instruments and measures designed to assess metacognitive performance, many of them based on Flavell s Model of Cognitive Monitoring andas well as Nelsons and Narens model. The present study focused on gaining a better understanding of metacognitive monitoring, which is usually assessed through judgements, which represents one way of measuring metacognition. The aim of the present study was to investigate children s metacognitive monitoring during the execution of three subtests of the BMI (Multidimensional Battery of Child Intelligence), based on the Cattell-Horn-Carroll s model of intelligence. The subtests chosen assessed quantitative knowledge, crystallized intelligence and fluid intelligence. Participants were 44 fifht-year students, and each child was individually evaluated. Following each of the subtests, children were asked to estimate their performance. Results showed that children s repertoire included metacognitive abilities, and some metacognitive monitoring rates were better for quantitative knowledge . When these abilities were compared relative to cognitive performance, those with the highest scores on the intelligence subtests demonstrated better metacognitive monitoring. These results, obtained with Brazilian children, are compared with results reported in the international literature, and the implications in terms of promoting metacognitive training are discussed. / A metacognição pode ser entendida como o conhecimento que o indivíduo possui sobre seu próprio funcionamento cognitivo, o que lhe permite planejar, monitorar, regular e avaliar suas atividades cognitivas. Estudos da área têm sido conduzidos para produzir instrumentos e medidas confiáveis do desempenho metacognitivo dos indivíduos, diversos deles tendo como referencial teórico os modelos formulados por Flavell e Nelson e Narens. Alguns destes instrumentos são escalas de autorrelato. O monitoramento metacognitivo, foco do presente estudo, é avaliado com frequência por meio dos julgamentos, que constituem outra ferramenta de avaliação da metacognição. O presente estudo teve como objetivo investigar o monitoramento metacognitivo de crianças durante a realização de três subtestes que compõem a Bateria Multidimensional de Inteligência Infantil: Desempenho em Matemática, Vocabulário Geral e Indução. O referencial teórico desta bateria é o Modelo Cattell-Horn-Carroll de inteligência e os subtestes referidos são destinados à avaliação das capacidades de conhecimento quantitativo, inteligência cristalizada e inteligência fluida, respectivamente. Participaram do estudo 44 alunos do quinto ano do Ensino Fundamental. Eles realizaram, individualmente, os três subtestes da BMI, e foram solicitados a emitir estimativas acerca de seu desempenho; estes julgamentos correspondem ao monitoramento metacognitivo. Os resultados indicaram que a amostra já apresenta habilidades de monitoramento cognitivo, e algumas medidas de monitoramento mostraram-se significativamente melhores para o subteste Desempenho em Matemática. Quando as habilidades de monitoramento foram comparadas de acordo com o desempenho cognitivo dos indivíduos, foram observados melhores índices de monitoramento metacognitivo nos indivíduos com melhor desempenho nos. Os dados são relevantes para confirmar, na população nacional, as informações da literatura internacional, e também para discutir a importância do incentivo e estímulo ao treinamento das habilidades metacognitivas.

La première partie de ce travail de thèse est une revue de la littérature portant toutd'abord sur les origines du concept de métacognition et sur les différentes définitions etmodélisations du concept de métacognition proposées en sciences de l’éducation etpsychologie développementale. Sont ensuite abordées les expérimentations proposées dans lechamp de la psychologie cognitive et les études menées dans le domaine spécifique de lamétamémoire. L’utilisation en psychologie cognitive du concept de métacognition estégalement évoquée, à travers la littérature portant sur les liens existants entre métacognition etconscience de soi. Enfin, le dernier point abordé dans cette revue de la littérature porte surl’utilisation en pratique clinique du concept de métacognition, notamment concernant lesaltérations métacognitives dans la schizophrénie.La deuxième partie de la thèse est consacrée aux études expérimentales réalisées.L’objectif de ces études était de développer et d’explorer dans une population non clinique lescaractéristiques d’un outil de mesure de la conscience métacognitive sur la mémoire à courtterme, la mémoire de travail, la mémoire épisodique verbale, les fonctions exécutives, et lacognition sociale. Nous avons évalué dans une première étude l’impact de cette procéduremétacognitive sur les performances cognitives. Une deuxième étude avait pour objectifd'explorer la pertinence de l’utilisation de l’évaluation « on-line » de la consciencemétacognitive, pendant la tâche neuropsychologique, comparativement à une procédure «end-line », juste après la passation du test neuropsychologique, ainsi que l’impact des mesuresd’estime de soi, anxiété et symptomatologie dépressive sur les scores de consciencemétacognitive « on-line ».Dans la troisième partie de cette thèse, les résultats sont discutés, et mis enperspectives avec l’objectif, à savoir utiliser cet outil de mesure de la consciencemétacognitive auprès d’une population de sujets souffrant de schizophrénie. / The first part of this thesis is a literature review focused on the origin, the differentdefinitions and models of the concept of metacognition in educational science anddevelopmental psychology. This literature review focused also on the cognitive psychologyexperiments, in the specific area of metamemory. The use of cognitive psychology concept ofmetacognition, through the literature on the links between metacognition and self-awarenessis then discussed. Finally, the last point in this literature review focused on the clinical use ofthe concept of metacognition, particularly concerning metacognitive alterations inschizophrenia.The second part of the thesis is devoted to experimental studies. The aim was todevelop and explore the characteristics of a metacognitive awareness measurement tool onshort-term memory, working memory, episodic memory verbal, executive functions andsocial cognition in a non-clinical population. The impact of this metacognitive process oncognitive performance, the relevance of an "on-line" metacognitive awareness measure(during the neuropsychological task), and an "end-line" metacognitive awareness measure(just after the award of neuropsychological testing) were explored. The impact of measures ofself-esteem, anxiety and depressive symptoms on metacognitive awareness scores "on-line"were studied.The third part of this thesis proposed to discuss the different results found and theappropriateness of using metacognitive awareness assessment tool with persons sufferingfrom schizophrenia.
