Recently, equine assisted learning (EAL) has emerged as a novel approach to building resiliency competencies in at-risk youth. This mixed-methods study presents evaluation results for an 8-week community-based EAL program with 83 young women (age 13-18 years) with a history of interpersonal trauma. Analyses examined changes in self-reported mental health symptoms (posttraumatic, depression) and resiliency factors (sense of mastery, sense of relatedness, emotion regulation) from pre- to post-test and at 1-month and 6-month follow-ups. Changes in outcomes were also correlated with intervention processes (attendance, session ratings) to see if program experiences were associated with differential outcomes. Results showed that EAL has potential in improving resiliency outcomes, at least for those participants who derived greater satisfaction and value from the sessions. Many improvements were sustained over the long term. Participants' qualitative feedback provided insight into their subjective experiences and highlighted the unique role that horses played in the EAL process.

Physical activity and classroom design changes are beneficial means to reduce stress, and enhance well-being. Results across some studies however, are mixed. Shanker Self-Reg™ supports the use of physical equipment and design as a means of managing arousal and tension levels. Previous research lacks rich description of educators' understanding of equipment and design, Self-Reg, and how this understanding affects the way it is implemented. In the current study, educators' understanding of Self-Reg, how this understanding influenced educators' approach to the school environment, and if one workshop was enough to inspire individuals to adopt a Self-Reg approach were explored using thematic analysis. Participants included educators from schools with beginner and intermediate-level experience in Self-Reg. The analysis produced eight themes and 8 sub-themes. Participants' knowledge of Self-Reg influenced their approach to their environments. Although one workshop may have inspired interest in the framework, it was not enough to shift educators' current practice.

There is little research devoted to exploring psychology's historical and discursive development. Psychological knowledge is generally presented as the contributions of individuals, but without context. The social, political, and economic aspects of psychology's development are scarcely discussed, including how the discipline came to be considered a science. This thesis project explored the history of the development of psychology. Specifically, psychology's claim to scientificity via the appropriation of the medical model of disease, and accordingly, the instantiation of the categorical paradigm of mental illness were examined. The discontinuous events that shaped psychology and its hallmark of scientificity were explored, including extensive concept transformations, political agendas, and marketing strategies. These practices were then explored in a practical way using the conception of clinical depression and the role of antidepressants as the first-line treatment for depression in the USA. This exploration revealed psychology's socio-historical contingencies and its agenda of prediction and control.

ABSTRACT

The Propensity Toward Extremist Mind-Set as Predicted

by Personality, Motivation, and Self-Construal

Nick Fauset

Multivariate regression analyses were used to determine the effects of Personality (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness), Motivation (External, Amotivation, Intrinsic, and Identified), and Self-Construal (Independent and Interdependent) on three domains of Extremist Mind-Set (Proviolence, Vile World, and Divine Power). Participants consisted of first year undergraduate students (209 females, 76 males) enrolled in Introductory Psychology (N=279) and/or Introductory Economics (N=7), whom participated for course credit. The Motivation measure was problematic for students to complete and this variable was dropped from the model due to missing data. Decreases in Neuroticism, Openness, Agreeableeness, and Interdependent were significantly correlated with increases in Proviolence. Decreases in Agreeableness were correlated with increases in Vile World. Decreases in Openness, and increases in Agreeableness and Interdependent were significantly correlated with increases in Divine Power. These observations provide an interesting perspective on the types of Canadian undergraduate students who are more likely to score highly on measures of Extremism.

This research project focused on the positive behaviour changes in First Nations youth as a result of participation in a community-based recreation program. The study was a secondary analysis based on a qualitative data set. Both adults and youth were interviewed in one-on-one and focus group settings in 12 First Nations communities across Ontario. The data was analyzed using a grounded theory approach and a substantive model was formed based on the themes that emerged from the data. The most significant of these themes were the job of the role model, self-esteem and self-efficacy. The issue of overcoming shyness and peer mentoring are also discussed.

Using rodent models, it is possible to study the behavioural and physiological outcomes of early life stress and the influences on normal mammary gland development and carcinogenic risk. Results demonstrate that the experience of three weeks of prolonged maternal separation (LMS; 4 hrs/day) increased the susceptibility of adult, but not pubertal, female BALB/c mice to engage in higher levels of depressive-related immobility behaviour and lower levels of active floating (a suggested adaptive coping behaviour) in the acute forced swim test, than offspring that experienced three weeks of brief separation (BMS; 15 min/day) events. Despite the increased immobility behaviour, adult LMS female offspring demonstrated lower basal corticosterone levels relative to BMS females. However, the experience of chronic early-life stress, regardless of the length, results in greater changes between non-stressed and stressed corticosterone levels (i.e. stressor reactivity) in adult females compared to their male counterparts. These changes were associated with decreased glucocorticoid receptor and coactivator-associated arginine methyltransferase 1 protein expression in mammary gland of female LMS mice at young adulthood, highlighting potential mechanisms underlying their heightened risk of mammary tumourigenesis. These data suggest that early life environments can induce behavioural and physiological alterations observed in adulthood, which may have an influence on the likelihood of malignancies developing in the breast.

Addiction can lead to a plethora of health, social and economical problems. Substances are used for mood regulation, and therefore, waking day mood is extremely important during recovery of alcohol and drug addiction. The current study examined the effects of Meditation and Sleep Mentation Therapy on mood levels. All participants were male, and currently in treatment programs or early stages of recovery from alcohol and drug addiction. Participants were tested for anxiety and depression and were asked to provide a recent dream, prior and post to participating in the intervention. Dreams were scored using Hall and Van de Castle guidelines for scoring imagery. Results are consistent with previous research in that mood levels changed over the course of the meditation period. Implications for future research are discussed as well as applications of Sleep Mentation Therapy and Meditation in clinical and applied practice.

Wetlands were once widespread in southern Ontario, but many have been drained through land use changes. Using a case study of twelve landowners in the Kawartha region, I explored motivations for restoring wetlands. Psychological research suggests that people who are more connected to nature and attached to place are more likely to behave sustainably. Results showed that having land available and receiving funding were necessary preconditions. Connectedness to nature and place attachment were motivations, as were personal benefits and having a supportive social community. Challenges included: the Permit to Take Water, paperwork and bureaucracy, delays and timing, and economic restrictions. Positive outcomes were: increased property value and crop productivity; personal enjoyment of wetlands; and improved wildlife habitat and water quality. Negative outcomes were: `nuisance' wildlife, trespassing, and a lack or excess of water. This is a novel study exploring nature connectedness, place attachment and wetland restoration qualitatively in southern Ontario.

Dreams that occur in bereavement have been mainly overlooked in the psychological literature. This study focuses on the most memorable dreams of the bereaved that contain imagery of the deceased. There were 52 participants who completed the study via email. The main goal of the study was to investigate the occurrence of common themes in the dreams that have the deceased as a character. It was hypothesized that the most memorable dreams are memorable because they positively influenced the dreamers waking life grief process, which was partially supported. Furthermore, it was expected that that the most memorable dreams will have a greater frequency of positive elements and a lower frequency of negative elements than the normative data on dreams, which was partially supported. These findings support past research on dreaming of the deceased and expand the impact that these types of dreams can have on the grief process.

Near-hand benefits are seen when individuals are able to process targets more quickly, accurately, and with greater precision when a hand is placed near, rather than far from a target. One possibility is that near-hand stimuli recruit visual-tactile bimodal cells. Research reports that placing a hand near a target delayed immediate saccade onset and speeded delayed saccade onset. Study 1 examined saccade onset to targets appearing near a real hand, a realistic fake hand, or a non-hand visual cue. Immediate saccades were facilitated and delayed saccades were slowed with a real hand in the display, in comparison to a fake hand and no-hand. To establish the link between near-hand effects and bimodal cells, Study 2 used repetitive transcranial magnetic stimulation (rTMS) to depress cortical activity in PMd. RTMS did not induce a reversal of interference induced by near-hand, congruent targets. However, a reversal of the hand effect was found in the stimulation group; a real hand in the display may delay immediate saccades and improve delayed saccades post-stimulation. This finding may double dissociate the effect of the real hand from the fake hand and may be inconsistent with the hypothesis that the hand is attracting attention.
