High-Risk Sexual Behaviour, Computer Experience And The Internet, Amanda E. Nosko
High-Risk Sexual Behaviour, Computer Experience And The Internet, Amanda E. Nosko
Theses and Dissertations (Comprehensive)
This study examined the relationships between computer use, sexually explicit material found on the Internet, and sexual attitudes and behaviours and the use of the Internet for conducting large surveys. The first issue explored if and how computer experience contributed to online behaviour and perceptions about sexually explicit material. In addition, sexual attitudes and behaviours were examined with respect to computer experience to assess potential relationships. The methodological question contrasted the use of traditional supervised paper-and-pencil survey techniques with supervised and unsupervised use of the Internet. This design allowed for comparison of use as a function of supervision and format …
Intuition And Correspondence Between Implicit And Explicit Self-Esteem, Mervyn Lee Whitfield
Intuition And Correspondence Between Implicit And Explicit Self-Esteem, Mervyn Lee Whitfield
Theses and Dissertations (Comprehensive)
Implicit self-esteem has recently been the focus of much research. Implicit self-esteem is distinct from explicit self-esteem and uniquely contributes to the prediction of behaviour. Relatively little is known about the nature of implicit self-esteem, however. This research examines moderators of the relation between implicit self-esteem and self-reports of self-esteem. A stronger focus on intuition was expected to increase the relation between implicit self-esteem and self-reports of self-esteem. Study 1 concerned whether high faith in intuition was associated with self-reports of self-esteem that more closely reflect implicit self-esteem. Implicit self-esteem, explicit self-esteem, and faith in intuition were measured. This study …
A Policy Analysis Of Two Preschool Prevention Programs In Ontario, Seema Aggarwal
A Policy Analysis Of Two Preschool Prevention Programs In Ontario, Seema Aggarwal
Theses and Dissertations (Comprehensive)
The purpose of this research was to examine issues relevant to best practices for preschooler mental health prevention policy so as to inform future prevention policy. Data were gathered through the examination of two preschool prevention programs, Ontario Early Years Centres (OEYCs) and Healthy Babies, Healthy Children (HBHC). These prevention programs were examined with respect to four major issues: (a) the ideology and origins of the program, (b) theoretical underpinnings, (c) research base, and (d) implementation and adaptation issues. To explore these four issues, qualitative methods were used in the form of document reviews (two documents for the Early Years …
Towards A Good Life: One Family's Experiences With Individualized Supports, Alison Baxter
Towards A Good Life: One Family's Experiences With Individualized Supports, Alison Baxter
Theses and Dissertations (Comprehensive)
Individualized funding and supports for people with a disability have emerged in Canada as an alternative to traditional supports such as group homes and day programs. In this thesis, I examine one family's experiences with individualized disability-related supports. From the perspective of an individual with an intellectual disability and her family members, friends, support workers and service providers, the benefits and challenges of individualized supports are profiled. Furthermore, how individualized supports impact upon relationships and community inclusion for this individual is explored along with the experiences of parents, siblings and support workers. As a qualitative study, information was gathered from …
Cross-Sensitization/Tolerance Between Wheel Running And Amphetamine And Morphine In Rats, Clint Inkster
Cross-Sensitization/Tolerance Between Wheel Running And Amphetamine And Morphine In Rats, Clint Inkster
Theses and Dissertations (Comprehensive)
Two experiments were conducted to determine whether cross-sensitization/tolerance between wheel running and the drugs amphetamine and morphine is possible in male Sprague Dawley rats. Each experiment compared a non-wheel control group and a chronic wheel access group of rats. Following a 24 day period of wheel access all animals were presented with a drug and saline challenge test (counterbalanced) with either 1 mg/kg of amphetamine (Experiment 1) or 10mg/kg or morphine (Experiment 2). Prior to the challenge tests all animals were habituated to the novel testing environment in two 1 hr sessions (Experiment 1) or one 2 hr session (Experiment …
Listening To The Voices Of Women Living With Hiv/Aids: A Qualitative Study Of Psychosocial Impact And Quality Of Life Issues, Edna Aryee
Theses and Dissertations (Comprehensive)
In spite of the increasing number of women infected with HIV around the world, little is known about the psychosocial experiences of these women. In the mid-1990s, medical advances dramatically altered the experiences of living with HIV/AIDS. The shifting medical climate raised new social and psychological questions such as coping strategies and the possibility of gaining access to resources and services in the community. In this qualitative study, I examined how 5 women living with HIV/AIDS in Southern Ontario deal with their daily psychosocial needs and challenges. Based on a life history methodology, responses of participants were coded and analyzed …
Syntactic Processing In Individuals With Dyslexia: Using Erp To Address The Debate, Hilary Brown
Syntactic Processing In Individuals With Dyslexia: Using Erp To Address The Debate, Hilary Brown
Theses and Dissertations (Comprehensive)
Behavioural and ERP data were collected from university and college students with and without dyslexia to determine if a deficit in syntactic processing in post-secondary students with dyslexia can be explained by the degree of phonological processing deficits. Participants read and listened to sentences of differing syntactic complexity and working memory load, particularly object relative and subject relative sentences. Slow cortical waves showed greater negativity for the objective relative sentences as the sentence progressed for the control participants regardless of presentation format. The same result was seen for the participants with dyslexia when presented with sentences in an auditory format. …
'If I Wasn't Friends With These People, I Probably Wouldn't Have Adjusted Too Well': Friendship Development And University Adjustment Among First-Year University Students, Vanessa Buote
Theses and Dissertations (Comprehensive)
Two studies sought to examine the relationship between new friendship quality and university adjustment. In Study 1, 706 students completed the Openness subscale of the NEO-FF Form S and the Openness to Friendship Scale in August 2005. In November, these students completed the Student Adaptation to College Questionnaire and the McGill Friendship Questionnaire-Friends Functions. Results indicated that a significant positive relationship existed between quality of new friendships and university adjustment. Significant differences emerged between commuter and residence students in terms of number of new friendships, openness to new friendships and adjustment. Study 2 consisted of an in-depth qualitative interview with …
The Development Of Wheel-Induced Feeding Suppression In Male And Female Rats, Olivia Dalton-Jez
The Development Of Wheel-Induced Feeding Suppression In Male And Female Rats, Olivia Dalton-Jez
Theses and Dissertations (Comprehensive)
Access to a running wheel causes a feeding suppression in adult rats (Afonso & Eikelboom, 2003) but it appears this wheel induced feeding suppression is not evident in weanlings (Cortright, Chandler, Lemon, and DiCarlo, 1997). This ad lib wheel and food model (ALWF) has been suggested as an animal model of anorexia nervosa (AN). Two characteristic features of AN are the disorder's very specific age of onset and the marked sex difference in incidence, with the majority of cases first becoming evident in females during puberty. It is not clear how much of the genesis of and expression of this …
Prerequisites For Reading Proficiency In Preschoolers, Iuliana Elena Faroga
Prerequisites For Reading Proficiency In Preschoolers, Iuliana Elena Faroga
Theses and Dissertations (Comprehensive)
The impact of a training program that combined phonological awareness activities with instruction in the alphabetic principle and teaching of basic vocabulary items (Zimmer, 2003) and commonly used words in school (Scarborough, 2003) was evaluated through a repeated measures design with a control group. The intervention targeted low-income preschool English-as-a-second language children (ESL) and low-income English speaking children, as well as middle-class ESL children. The results show that the children participating in the intervention group showed significantly better performance on phonological awareness and trained vocabulary measures than children in the control group. Additionally, ESL trained children demonstrated significantly better performance …
Pigeons' Memory For Sequences Of Light Flashes When Gap Duration Is Controlled, Dwayne Keough
Pigeons' Memory For Sequences Of Light Flashes When Gap Duration Is Controlled, Dwayne Keough
Theses and Dissertations (Comprehensive)
In Experiment 1, pigeons were trained at a 1-s dark and a 1-s houselight illuminated delay interval to discriminate between sequences of two and four flashes of light (feeder illumination). These sequences could be discriminated on the basis of the number of flashes, the number of gaps, or the duration of the gap between flashes. A choose-few bias was obtained at extended dark delays, but no biased forgetting was observed at extended illuminated delays. The pigeons may have confused long dark delays with the longer gaps between flashes on few sample trials. In Experiment 2, additional sample sequences were included …
Planning For The Close And Distant Future: The Impact Of Temporal Distance On Task Completion Prediction, Johanna Peetz
Planning For The Close And Distant Future: The Impact Of Temporal Distance On Task Completion Prediction, Johanna Peetz
Theses and Dissertations (Comprehensive)
Accurate project completion estimates are part of successful project completion. Thus, it is important to identify factors that reduce the tendency to make overly optimistic project completion predictions (Buehler et al., 2002). This research investigated the effect of temporal distance on project completion predictions. A review of past research provided evidence that could lead to a prediction of either increased or decreased optimism with increasing temporal distance. In a first study, participants predicted the completion date of a hypothetical school assignment that would begin either tomorrow (close future) and next term (distant future). Participants predicted to complete the project earlier …
Longing To Be Heard: Examining Sense Of Community And Participation Through The Voices Of Youth, Marcie D. Mckay
Longing To Be Heard: Examining Sense Of Community And Participation Through The Voices Of Youth, Marcie D. Mckay
Theses and Dissertations (Comprehensive)
Youth often feel powerless and alienated in their communities and have expressed that they are not seen as contributing citizens. This study investigates the relation between sense of community and participation of youth aged 12-15 residing in a disadvantaged Atlantic Canadian community. The research design is a one-group, pre/post-test survey, and an intervention. The intervention is the formation of a youth action committee (YAC) from a self-selected stratified sample (N=36) drawn from randomly selected classrooms within three schools. The YAC worked collectively on a number of issues in their community using an action model. Results highlight the concerns and outcomes …
Assessing Quality Of Life For Clients Of Langs Farm Village Association: A Case For Inclusion Of The Social Determinants Of Health Approach In Addressing Quality Of Life In A Community Health Centre Setting, Annette A. Penney
Theses and Dissertations (Comprehensive)
In my master’s thesis research I investigated the relationship between participant inclusion in Langs Farm Village Association, a local community health centre, and quality of life. A quality of life survey which I developed based on prior research conducted by the Canadian Policy Research Network (2001) was administered to 130 individuals, 65 participants who attended a program and/or service at Langs (Langs group), and 65 participants who did not (non-Langs group). Results of multivariate ANOVA indicated group differences of statistical significance on four out of eleven subscales of my quality of life survey. Community residents who participated in a program …
Conceptualizing And Analyzing The Pleasure Travel Decision-Making Process, Wayne William Smith
Conceptualizing And Analyzing The Pleasure Travel Decision-Making Process, Wayne William Smith
Theses and Dissertations (Comprehensive)
This dissertation explores methodological approaches to the study of the pleasure travel decision-making process. Specifically, this dissertation explores methodological approaches to studying the relative importance of motivations and constraints in the travel decision-making process. Three segmentation approaches were used, principle components analysis, cluster analysis and unidimensional sequence alignment. 522 students from two South-western Ontario, Canada universities participated in this study examining their decision-making in relation to potential travel plans for reading week (February 2005). The results indicate that individuals potentially have a multitude of constraint levels to over-come as part of the initial travel decision-making process. If these base constraints …
The Effects Of Meritocracy Beliefs On Women’S Well-Being After First-Time Gender Discrimination, Mindi D. Foster, E. Micha Tsarfati
The Effects Of Meritocracy Beliefs On Women’S Well-Being After First-Time Gender Discrimination, Mindi D. Foster, E. Micha Tsarfati
Psychology Faculty Publications
This study examined how meritocracy beliefs may buffer women from the negative psychological effects of an acute situation of gender discrimination. Although some research indirectly suggests that believing the meritocracy exists may increase well-being, group consciousness theories (e.g., Bartky, 1977) suggest that disbelieving the meritocracy exists will enhance psychological adjustment to gender discrimination. Women who reported little past experience with discrimination, and either believed or disbelieved the meritocracy exists were exposed to either a laboratory situation of discrimination or a non-discrimination failure (control) condition. Consistent with group consciousness theories, women experiencing discrimination reported greater well-being if they disbelieved the meritocracy …
Experiences And Expectations: What Prompts An Educator To Use Computers In The Classroom?, Craig Ross
Experiences And Expectations: What Prompts An Educator To Use Computers In The Classroom?, Craig Ross
Theses and Dissertations (Comprehensive)
Charged with the task of providing today's youth with the education they need, many school boards across North America have invested large sums of money in computer technology. However, although the technology is being installed in the schools, many educators are not using the technology to its full potential as a learning tool. In the present study, elementary (n = 148) and secondary (n = 150) educators completed one survey which assessed two domains believed to influence an educator's decision to integrate computer technology into his/her classroom. The first domain was comprised of gender and teaching level (elementary versus secondary), …
Cultural Diversity At Family And Children's Services Of The Region Of Waterloo: An Evaluation Of A Cultural Competency Training Program, Jessica Leigh Vinograd
Cultural Diversity At Family And Children's Services Of The Region Of Waterloo: An Evaluation Of A Cultural Competency Training Program, Jessica Leigh Vinograd
Theses and Dissertations (Comprehensive)
Cultural competence among child welfare practitioners is imperative given rapidly changing Canadian demographics, current inadequacy in the delivery of social services due to ethnocentric bias, and the insufficiency of educational programs in providing multicultural training for future practitioners. This study investigated the extent to which a specific training program influences multicultural competencies. In Ontario, child welfare employees (N = 61) completed the Multicultural Awareness Knowledge and Skills Survey (MAKSS) (D'Andrea, Daniels, & Heck, 1991) on two separate occasions. A 2 (pre, post) x 2 (experimental, comparison) mixed-model design was used to test the hypothesis that experimental participants would score significantly …
Does A Past Conflict Still Sting? The Influence Of Recall Style And Self-Esteem On The Impact Of Conflict Memories, Huan Jacqueline Ye
Does A Past Conflict Still Sting? The Influence Of Recall Style And Self-Esteem On The Impact Of Conflict Memories, Huan Jacqueline Ye
Theses and Dissertations (Comprehensive)
The current research examined whether the impact of people's past conflicts on their current relationships is associated with (1) the way people think about the conflicts, (2) their self-regard. Specifically, we expected that people's relationships should be more negatively influenced if they recall conflicts in a vivid manner, focusing on "how" the conflicts happened and recalling them in vivid detail, rather than if they recall conflicts in a pallid manner, focusing on "why" the conflict occurred and recalling little detail. We also predicted that past conflicts are more likely to adversely affect the appraisals of the relationships of low self-esteem …
A Comparison Of Techniques For Measuring Automatic Retrieval In Conceptual Priming, Jennifer C. Major
A Comparison Of Techniques For Measuring Automatic Retrieval In Conceptual Priming, Jennifer C. Major
Theses and Dissertations (Comprehensive)
The speeded response technique has provided pure estimates of automatic retrieval in perceptual memory tasks. The present study was designed to investigate whether pure automatic retrieval could also be evidenced in a conceptual task. Subjects were encouraged to generate category exemplars using strictly automatic retrieval by presenting practice trials that did not allow responding with previously studied items and by encouraging speed of responding. This speeded condition was compared to a baseline condition in which conscious retrieval was not possible and to an explicit condition in which conscious retrieval was required. Average RTs in the speeded condition were the same …
Fmri Study Of Cutaneous Illusions, Peggy Joanne Planetta
Fmri Study Of Cutaneous Illusions, Peggy Joanne Planetta
Theses and Dissertations (Comprehensive)
We conducted three block-design experiments using functional magnetic resonance imaging (fMRI) to investigate the cortical areas involved in: 1) processing passively presented pneumatic stimulation, 2) the perception of tactile apparent motion (TAM), and 3) the perception of the cutaneous “rabbit.” In the first experiment (Arm Localizer), periods of random pneumatic stimulation delivered to the ventral right forearm were alternated with periods of rest. The results were consistent with previous research showing activation in the contralateral precentral and postcentral gyri, as well as higher parietal cortical areas. In the second experiment (Apparent Motion), periods of consecutive air puffs presented along the …
Becoming: Stories Of L'Arche Children, Caroline A. Currie
Becoming: Stories Of L'Arche Children, Caroline A. Currie
Theses and Dissertations (Comprehensive)
In this study, I explore what it means to be a child of L’Arche from a combined narrative and autoethnographic approach. L’Arche is an international federation of intentional communities where individuals with a developmental disability and non-disabled individuals live together in the spirit of the Beatitudes. While much is written about the history and philosophy of L’Arche, and the personal experiences of its adult members, L’Arche’s narrative does not include the voice of its children. Therefore, my study aims to give voice to the stories of L’Arche children so they may be included in the narrative of L’Arche. It is …
Why Do Young Children Forget Where They Learned Information? The Relation Between Source Monitoring, Theory-Of-Mind Understanding And Suggestibility, Angela D. Evans
Why Do Young Children Forget Where They Learned Information? The Relation Between Source Monitoring, Theory-Of-Mind Understanding And Suggestibility, Angela D. Evans
Theses and Dissertations (Comprehensive)
In Study one, Fifty young children (3- to 5- year-olds) watched a video and were then interviewed about the video by a Knowledgeable interviewer, who had watched the video with the children, and a Naive interviewer, who had not seen the video. Children were asked yes/no recognition questions, half of which contained misleading suggestions. After five to seven days, children were asked the same yes/no recognition questions by a third Naïve interviewer. Children then completed a source-monitoring task Followed by three theory-of-mind tests. Study two followed the same methodologies as Study one but with an increased sample size (72 children), …
Children's Ability To Use Time-Lines To Recall The Order And Duration Of Single And Repeated Actions, Leanne Lynn Gosse
Children's Ability To Use Time-Lines To Recall The Order And Duration Of Single And Repeated Actions, Leanne Lynn Gosse
Theses and Dissertations (Comprehensive)
This study examined the ability of children aged 4-8 to recall temporal information verbally and using a visual 'time-line'. Forty-five children participated in an activity (making a picture of the sky at night) with the researcher, followed by a series of recall tasks. Children were asked to recall location, duration and sequencing information about single autobiographical events that parents provided, as well as single and repeated events from the activity. Results demonstrated developmental increases in children's ability to provide temporal information. The 7-8 year olds were always more accurate than the 5-6 year olds, followed by the 4 year olds. …
Forging And Severing Connections Between Historical Injustices And Current Experience, Gregory Roy Gunn
Forging And Severing Connections Between Historical Injustices And Current Experience, Gregory Roy Gunn
Theses and Dissertations (Comprehensive)
Past research on temporal self-appraisal theory has revealed that individuals are able to maintain a positive sense of self by subjectively moving favourable past events forward and unfavourable past events backward in time. The current study extends past work by examining whether individuals alter subjective distance from historical injustices to protect their collective identity. Men, as members of a perpetrator group, may perceive past injustices against women as a threat to their collective identity. As such, men may be motivated to subjectively move past injustices backward in time. On the other hand, women, as members of a victim group, may …
The Effect Of Delta9-Tetrahydrocannabinol (Thc) And Cb1 Antagonists On Sucrose And Quinine Palatability: Direct Measurement With The Taste Reactivity Test, Maegan Jarrett
Theses and Dissertations (Comprehensive)
Anecdotal reports suggest that cannabinoid agonists enhance palatability and that antagonists reduce palatability; however there has been little direct experimental evidence for these claims. The taste reactivity (TR) test is a direct measure of palatability in rats (Grill & Norgren, 1978). In Experiments 1 and 4, the taste reactivity (TR) test was used to evaluate the potential of delta-9-tetrahydrocannabinol (THC) to modify both sucrose and quinine palatability. The TR test revealed that THC (0.5 mg/kg) increases the palatability of sucrose solutions at 120 min post-injection, regardless of the sucrose concentration. THC (0.5 mg/kg) also decreased the aversiveness of the quinine …
Resident Participation Across The Lifecycle Of A Primary Prevention Initiative, Alexandra Kissin
Resident Participation Across The Lifecycle Of A Primary Prevention Initiative, Alexandra Kissin
Theses and Dissertations (Comprehensive)
Resident participation is a key aspect of primary prevention initiatives that follow a community-driven approach. This study examines the evolution of resident participation at three Ontario sites (Guelph, Cornwall, and Walpole Island) of the primary prevention initiative Better Beginnings, Better Futures. The main research questions were focused on discovering the nature, barriers, facilitators, and impacts of resident participation and the roles that residents played at each of the three phases of the sites' lifecycles (i.e., the early years, the middle years, and the later years). Data collection involved a review of archival documents for the early and middle years and …
Examining The Factors That Promote Sustained Engagement In Young People, Marla C. Pender
Examining The Factors That Promote Sustained Engagement In Young People, Marla C. Pender
Theses and Dissertations (Comprehensive)
Little research to date has explored the kinds of factors that promote sustained engagement in young people. In order to address this gap in the literature, 20 individuals who attended national youth conferences (the goal of which being to promote engagement above and beyond the conferences themselves) between one and 14 years earlier were interviewed about their experiences before, during, and after the conferences. Specifically, participants were asked to discuss their levels of involvement in their schools and communities after attending the conferences, as well as the factors that sustained or hindered their participation. Four emerging themes---the nature of the …
Prediction Of Childhood Externalizing Disorder Outcome: A Variable-Oriented And Person-Oriented Analysis Of Better Beginnings, Better Futures Data, Stephanie C. Cerutti
Prediction Of Childhood Externalizing Disorder Outcome: A Variable-Oriented And Person-Oriented Analysis Of Better Beginnings, Better Futures Data, Stephanie C. Cerutti
Theses and Dissertations (Comprehensive)
The current study identified risk factors associated with childhood externalize disorders. Intervention outcomes of children that took part in a community-based, early childhood prevention project, Better Beginnings Better Futures, were studied longitudinally from Grade 3 to Grade 6. Three intervention sites in Ontario (Cornwall, n = 108; Sudbury, n = 134; Highfield, n = 131) and two matched comparison sites in Ontario (Ottawa-Vanier, n = 116; Etobicoke, n = 87) were examined. Risk factors examined at multiple levels of analysis, including the individual, family, and community levels of analysis, were considered. It was expected that higher risk children would respond …
Biased Forgetting Effects In The Assessment Of Memory For Filled And Empty Intervals: Evidence For The Instructional Failure/Confusion Hypothesis, Stephen Gagne
Theses and Dissertations (Comprehensive)
According to the instructional failure hypothesis, the contextual similarity of the intertrial interval (ITI) and the delay interval (DI) is responsible for the choose-short bias that occurs when memory for filled intervals is tested. This hypothesis may also explain the choose-long bias for empty intervals, if birds confuse an extended DI with a long empty interval. In the present study, pigeons were trained in a within-subjects design to discriminate durations of a filled interval (2-s and 8-s of light), and durations of an empty interval (2-s and 8-s bound by two 1-s light markers). In order to disambiguate the ITI, …
