The encouragement of reflective writing through the development of self-regulation in planning and producing textAgafonoff, Annabel, n/a January 1997 (has links)
The dual problem space model of writing (Scardamalia, Bereiter and Steinbach,
1984) shows how writers develop their knowledge and understanding of the world
by reflecting on problems of substance and problems of presentation in planning a
composition. Reflective thought is attributed to a two-way communication
between a content problem space and a rhetorical problem space. The content
space involves the development of ideas, while the rhetorical space is concerned
with achieving various purposes in composition.
This thesis reports an instructional experiment comparing alternative approaches to
teaching the self-regulatory strategies required for the two-way process of
reflection. The experiment compared the dialogue approach of current practice,
which relies on the teacher to provide the linking operations between the two
problem spaces, with two experimental approaches which promote development of
self-regulatory strategies of reflection, so that students are able to sustain such a
two-way process independently. The experimental approaches are described as a
guided discovery approach proposed by Evans (1991) and an approach described
as cognitive apprenticeship developed by Scardamalia, Bereiter and Steinbach
(1984).
Three instructional programs were prepared by the author to represent the three
alternative approaches examined in the present study. The control program utilised
the dialogue approach of current practice in which the dialectical process is carried
on between teacher and student. The two experimental programs focused on promoting processes of self-questioning rather than questioning by an external
agent such as a teacher. The guided discovery program consisted of activities
which prompted self-questioning processes. The cognitive apprenticeship program
employed scaffolding in the form of procedural facilitation cues to stimulate the
self-questioning process.
A pre-test and post-test control group design was used involving three groups, two
experimental (guided discovery and cognitive apprenticeship) and one control
(dialogue), with instructional method as the independent variable and rated
reflectiveness of writing as the dependent variable. Instruction was concentrated on
teaching the two-way problem formulating and problem solving strategies of the
reflective process for opinion essays and factual exposition essays. The experiment
compared the effectiveness of programs by measuring changes in overall
reflectiveness of writing. Significant improvements were obtained for the
experimental teaching methods withrespect to opinion essays. This research
provided some support for the hypothesis that instruction which fosters self-regulation
of the planning process through processes of reflection results in more
reflective writing than instruction in which such regulation is prompted by the
teacher.

The Relationships Between Body Image, Leisure Time Physical Activity, And Composition Among People Living With Spinal Cord InjuryBassett, Rebecca 11 1900 (has links)
<p>Body image is an important component of physical and psychological health. Cash's
(2002) cognitive-behavioural model of body image is useful for understanding factors
related to body image, such as body composition and leisure time physical activity
(LTPA). Changes in body composition and LTPA following spinal cord injury (SCI)
may increase the risk of developing an unhealthy body image and may jeopardize the
overall health and well-being of people with SCI. Unfortunately, little research had been
conducted to explore factors related to body image in the SCI population.</p><p>The object of the current thesis was to examine body image in people with SCI, within
the framework of Cash's (2002) model. Specifically, we examined the relationships
between appearance and functional satisfaction, LTPA, and body composition in 61 men
and women with SCI. Pearson's correlations were calculated to examine the relationship
between body composition and body satisfaction. In order to compare body satisfaction
between men and women who engaged in some LTPA versus no LTPA, separate 2 (sex) x
2 (LTPA) ANOVAs were calculated for appearance satisfaction and functional
satisfaction.</p><p>We hypothesized that body composition would be negatively related to appearance
satisfaction and functional satisfaction such that higher body weight, percentage body fat
and waist circumference would be associated with lower levels of satisfaction. Further,
we hypothesized that after controlling for body composition, participants who engaged in
LTPA would have more appearance and functional satisfaction than those who did not.Finally, we hypothesized that body satisfaction would be more strongly related to
moderate-intensity LTPA versus mild-intensity LTPA, and resistance-LTPA versus
aerobic-LTP A.</p><p>In partial support of our hypothesis, body composition was significantly related to
appearance satisfaction for women only. Body composition was not significantly related
to functional satisfaction for men or women. The results of the ANOVAs indicate that
women were more dissatisfied with their appearance than men. However, contrary to
hypothesis, appearance satisfaction did not differ between men or women who engaged in .
LTPA versus those who did not. For men and women, those who engaged in mild or
moderate intensity LTPA were less satisfied with their physical function than those who
did not. Further, participants who engaged in resistance-LTPA were less satisfied with
their physical function that those who did not.</p><p>Results are discussed within the framework of Cash's model. Findings suggest that
people who engage in LTPA are less satisfied with their bodies than people who do not.
This finding was surprising because LTPA has been shown to improve body image in the
SCI population (Hicks et al., 2003). However, dissatisfaction with physical appearance or
physical function may motivate individuals to engage in LTPA. The theoretical and
practical implications of the current thesis are discussed. Prospective research is
necessary to further understand the directionality of the relationship between the
constructs of Cash's (2002) model, and to test SCI-specific variables as potential
mediators and moderators of the relationship between LTPA and body image.</p> / Thesis / Master of Science (MSc)

Prédiction des habiletés et habitudes de conduite automobile sécuritaire chez les conducteurs âgés : apport de la neuropsychologie cliniqueHazel, Mylène 12 1900 (has links)
L’insécurité routière chez les conducteurs âgés est attribuable en partie, aux effets délétères du vieillissement normal sur le fonctionnement cognitif. Les méthodes d’évaluation neuropsychologique par les tests ayant montré une certaine efficacité dans le cas du dépistage des habiletés de conduite chez les conducteurs âgés atteints d’affections neurologiques pathologiques, la présente thèse vise à évaluer la pertinence de cette approche chez les conducteurs vieillissants de la population générale. Le principal objectif de cette thèse est ainsi d’obtenir une vue d’ensemble sur le rôle et la sensibilité des mesures neuropsychologiques dans la prédiction des habiletés et habitudes de conduite automobile sécuritaire chez les conducteurs âgés. Dans la même perspective, la thèse explore d’autre part le rôle de variables sociodémographiques et psychologiques.
L’article 1 évalue la validité prédictive de sept tests des fonctions visuo-attentionnelles et de la mémoire de travail en regard des habiletés de détection périphérique chez 50 conducteurs âgés de 62 à 83 ans. L’étude sur simulateur de conduite comprend une condition de conduite simple et une condition plus soutenue incluant une distraction téléphonique de type « mains-libres ». Selon les résultats, certains tests cognitifs prédisent bien les temps de détection. En outre, la validité prédictive des tests est plus importante dans la situation de conduite plus exigeante. Cela dit, les résultats de l’article 2 révèlent que le recours aux stratégies d’évitement des situations exigeantes est plus prononcé chez les individus qui présentent des faiblesses à certains des tests neuropsychologiques proposés. Les résultats indiquent en outre que l’utilisation des stratégies d’évitement routier est plus fréquente chez les conducteurs ayant tendance à déprécier leurs habiletés de conduite générales, à exprimer une moindre perception de contrôle ainsi qu’une attitude défavorable à l’endroit des situations de conduite complexes ou risquées. Les stratégies d’évitement se révèlent donc comme des réponses autorégulatrices proportionnelles aux limitations cognitives et aux perceptions individuelles.
Dans les deux études, l’âge ne permet pas d’expliquer les différences individuelles, ceci ni en termes d’habiletés de détection périphérique ni de tendances autorégulatrices. Le rôle du genre est cependant plus nuancé.
Ainsi, le principal apport de la présente thèse réside dans la constatation que si d’une part, certaines limitations neuropsychologiques sont associées à une réduction des habiletés de détection périphérique, ces mêmes limitations s’accompagnent aussi de mesures autorégulatrices qui peuvent contribuer à réduire le risque routier. Il appert conséquemment que les méthodes de dépistage de l’insécurité routière chez les conducteurs âgés se basant sur l’évaluation des limitations cognitives et attentionnelles doivent également rechercher et évaluer la teneur de leurs comportements routiers autorégulateurs. Dans le contexte de vieillissement de la population, des interventions pourront également miser sur le renforcement de ces comportements. / The increase of crash rates in elderly population can be attributed in some part to the effects of normal aging on cognitive functioning. In the other hand, older drivers are likely to adopt self-regulated driving behaviours, such as driving habits to restrict their exposure to less complex situations. Neuropsychological assessments have shown some efficacy in the field of fitness-to-drive screening of older drivers suffering from neurological disorders. This thesis aims to assess the relevance of clinical neuropsychology in screening methods considering older drivers population. The main goal is thus to study the contribution and the sensitivity of neuropsychological testing in the prediction of skills and habits of safe driving among older drivers. In the same vein, the thesis investigates the role of other socio-demographic and psychological variables.
To this end, article 1 evaluates the predictive validity of seven tests of visuo-attentional functions and working memory efficiency in relation to peripheral detection task performances in 50 drivers aged from 62 to 83 years in a simulated car driving environment. The driving simulation consisted of a simple driving condition and a condition including a "hands-free" cell phone distraction task. The results indicate that some neuropsychological tests, as opposed to age, are good predictors of detection performances. In addition, the predictive validity of the tests is more important in the most challenging driving condition. The Corsi Block Tapping test, assessing visuospatial working memory, is revealed as on of the best predictor of detection skills.
Article 2 was carried from previous neuropsychological testing and self-administered questionnaires related to avoidance driving behaviours, drivers perceptions and attitudes. The results indicate that individuals who show higher difficulties in tests assessing visuospatial working memory, processing speed, and divided and selective attention capacities are significantly more likely to adopt avoidance driving strategies. The results also demonstrate that driving avoidance is higher among drivers who tend to depreciate their general driving skills, to express a lower perception of control and an unfavourable attitude towards risky driving. Avoidance strategies are thus proven to be self-regulatory responses which are proportionate to cognitive limitations and individual perceptions.
In summary, this thesis demonstrates that peripheral detection performances of older drivers in a simulated car study, are well reflected in neuropsychological testing assessing working memory and other attentional abilities. Since detection skills are crucial for driving safety, an indirect link can be established between neuropsychological measures and road safety among older drivers. It also seems that those drivers, who have greater cognitive limitations, are more likely to avoid challenging driving situations, thereby balancing their crash risk. It is concluded that fitness-to-drive assessments based on neuropsychological screening need to be complemented with the assessment of self-regulatory behaviors. In the context of an aging population, new interventions should focus on strengthening self-regulatory behaviors of older drivers.
