Analyzing this fact, the task of this dissertation points the phenomenon above the psychology view focalizing the family or the dynamic family as the main reason to children when they have problems in learning; to understand the dynamic family that make difficulties in each of its components. Have the standards been adopted in new families that promote this sensation of incapacity? What are the measurements corrections and preventions ones that can be done or not? To answer these questions was used a methodology of background knowledge and the main idea from this indirect interview was the research done in Maceió city, in the state of Alagoas with three mothers who have children having difficulties in learning. All of them studying in a private school. The results confirm the complexity involving social, cultural and educational aspects shown in this task and the importance of a dynamic family as a path to manage these families / É cada vez maior o número de crianças que apresentam dificuldades de aprendizagem. Atento a este fato, o presente trabalho de dissertação estuda esse fenômeno sob a ótica da psicologia atendo-se, mais especificamente, à família ou dinâmica familiar como fator promotor das dificuldades de aprendizagem, no intuito de compreender que dinâmica familiar é a que produz essas dificuldades em seus componentes; que padrões estão sendo adotados nas novas famílias que promovem esta sensação de incapacidade; que medidas corretivas e preventivas podem e/ ou devem ser tomadas. Para responder a este objetivo foi utilizada uma metodologia de natureza qualitativa O instrumento de coleta de dados foi a entrevista semidirigida e o cenário da pesquisa foi a cidade de Maceió, capital do Estado de Alagoas. Foram entrevistados os pais de crianças, com dificuldades de aprendizagem, oriundas de escola particular. Os resultados reafirmam a densa gama de aspectos sociais, culturais, pedagógicos e cognitivos envolvidos nestas questões, bem como destacam a relevância da dinâmica familiar na gênese e manutenção das mesmas

This study investigates student and instructor perceptions of the causes and effects of anxiety and motivation's effect on a student's ability to learn a second language. The study focused on the participant's perceptions of the causes and effects of anxiety, and relationships between anxiety and motivation, in both short-term and long-term learners.

Learning styles and readiness for self-directed learning were identified for 125 adult employees enrolled in self-paced training courses. The success of the self-paced instruction was measured by confidence to perform learned skills on the job. Confidence scores were compared across learning style types and self-directed learning readiness. It was concluded that self-paced training programs can be effective for a variety of learning style preferences. Additionally, adult employees who are highly self-directed will experience greater success in self-paced instruction than those less self-directed. The implication for businesses and academic institutions seeking to employ technology based, self-instructional programs is that a return on investment can be maximized by an examination of the target audience. Training programs which are self-paced may not generate the desired success which will translate into effective job performance for those adults who are not ready for self-directed learning.

The basis for this study was work done by Joy Reid (1987) of Colorado State University. Reid's work analyzed the pref erred perceptual learning styles of several groups of English as a Second Language students and one group of American students. The learning styles concept has been established on the theory that students have a particular mode through which they learn best. The learning styles analyzed in this study were: auditory, visual, kinesthetic, tactile, individual, and group. The objectives of this study were to determine the relationships that exist between the preferred perceptual learning styles of P.R.C. and American students and such variables as country where student is studying, native language, length of time in the U.S., and sex.

In this thesis, Stroop task performance was investigated (using behavioural, electrophysiological and functional magnetic resonance imaging (fMRI) techniques) in late and proficient adult bilinguals currently living in the second language (L2) environment. Monolingual participants, matched for age and handedness, were recruited as controls. The Stroop colour-word task was considered an appropriate tool to test the general hypothesis that bilingualism might influence executive or cognitive control processes. In Study One, a dual-task paradigm was used for assessing the lateralisation of language functions (given the linguistic nature of the Stroop paradigm used here) in the bilinguals (Macedonian-English/M-E). Bilinguals showed a more bilateral hemispheric involvement, for both languages, compared to monolinguals. These findings also provided supporting evidence for the hypothesis of greater right-hemispheric involvement for language in bilinguals. In Study Two, two behavioural Stroop task paradigms (manual and verbal) were used in order to assess the magnitude of the Stroop effect between the groups. Bilinguals (M-E, German-English/G-E) showed a trend of smaller interference scores across both languages compared to monolinguals. In Study Three, manual Stroop task performance with concurrent electroencephalograph (EEG) recording revealed that bilinguals had temporal shifts in the N400 component (of about 30-40 ms) for the interference comparison for both languages compared to monolinguals. Also, relative to monolinguals, M-E bilinguals (for both L1 and L2) and G-E bilinguals (for L2) had fewer electrodes over frontal and central sites with a significant amplitude difference in the interference comparison (i.e., a reduced interference effect). In Study Four, the neural substrates engaged during Stroop task performance were investigated using fMRI. In general, monolinguals showed greater activation in regions such as the prefrontal cortex and anterior cingulate (regions associated with good executive control). This suggested that relative to bilinguals, monolinguals require more neural resources to accomplish conflict resolution. Taken together, Stroop task performance in late and proficient bilinguals currently living in the L2 environment differed from that of monolinguals across all methods of investigation. It appears that cognitive processing changes at the executive level can be observed as a result of bilingualism. The results also provide some evidence for changes in L1 processing following late L2 acquisition, as similar results across both languages and tasks were observed for the M-E bilinguals. It is also possible that slight modifications to cerebral laterality as a result of the late learning of (and continuous exposure to) a second language could contribute to these differences in executive functioning. The language environment might therefore be a major factor in the lateralisation of language processing and executive functioning in bilinguals. These conclusions, though tentative and require further investigation, have important implications for language and executive processing in general and for theories regarding cognitive flexibility in bilinguals. / Auckland University Doctoral Scholarship
