Alcohol and cannabis use are prevalent among young adults in Canada. Additionally, heavier substance use is associated with an increased likelihood of experiencing negative consequences resulting from use. Given the potential for harmful consequences resulting from alcohol and cannabis use, it is important to understand why people use these substances. Childhood maltreatment has been identified as an important predictor of alcohol and cannabis use. However, less is known about the mechanisms underlying this relationship, though it seems emotion regulation may play an important role. This study explores the relationship between maltreatment and emotion dysregulation, in addition to the relationship between maltreatment and affective motives for using alcohol and marijuana. Results indicate that drinking to cope mediates the relationship between all measured forms of maltreatment and alcohol consequences. However, none of the motives individually significantly mediated the relationship between maltreatment and marijuana use consequences. Results, limitations, and future directions are discussed.

“Homeostatic beliefs” (HBs) denote a sense that one’s life path will remain stable in the long-term despite short-term disruptions. Two studies have been undertaken to explore whether HBs exist independent of other constructs, and to develop a scale with which to measure them. In Study 1, 158 undergraduate students completed a draft HB scale and theoretically related scales. Convergent and divergent validity were assessed with correlational and regression analyses: HBs are most strongly related to, but not redundant with, optimism, trait extraversion, and satisfaction with life. Using exploratory factor analysis, a six-item HB scale was derived. Study 2 is in progress, and will assess the construct validity of the HB scale by attempting to manipulate HBs to possibly influence individuals’ reactions to a mortality salience manipulation. We hypothesize that high HBs may buffer individuals from transient disrupting stimuli such as a mortality salience cue.

This thesis began largely as an exploration into right-wing political ideology and its relationship to The Authoritarian Personality proposed by Adorno, Frenkel-Brunswick, Levinson and Sanford (1950). It had initially been envisaged that contemporary examples would manifest themselves within many neo-Fascist or ‘White Pride’ style organisations and as an adage to their supposed historical underpinnings, would therefore be representative of modern day authoritarianism. As previously discovered by Eysenck and Coulter (1974) in their examination of British Fascists and Communists, the authoritarian syndrome is somewhat more complex to explain by way of reference to a number of radical semi-political organisations. Subsequently, the thesis was to take on a deeper and more philosophical direction as various parts of the literature were analysed and critiqued. And indeed to some extent the original proposal was abandoned in favour of a richer and more conceptual approach to our understanding of authoritarianism. This was discovered to be distinctly missing from the majority of the current literature in the field.

The goal of this dissertation was to examine how people pursue their personal goals in the context of an intimate relationship. Two studies were conducted; a daily diary study of dating partners’ joint activities and a longitudinal study of newly dating couples. In the daily diary study, people reported on their daily joint activities with their dating partners regarding whether their goals were met and how they were feeling during the given activity. The results showed that when people’s goals were met in an activity, their partners were able to accurately perceive that their goals were being met. However, when their goals were not met in the activity, their partners’ accuracy regarding their goals was only at chance levels. The partners’ overall levels of goal congruence did not predict the proportion of goal-congruent activities the partners participated in. However, the partners’ level of goal congruence predicted increases in life satisfaction, relationship commitment, and relationship satisfaction, as well as decreases in negative affect over time. In the longitudinal study, newly dating couples filled out measures of their goals, well-being, and relationship quality during their initial session. Three months later, the couples filled out measures of these same constructs again and answered questions about the goals that they reported pursuing during their initial session. Results showed that concurrently, the partners’ levels of goal congruence were associated with greater ability to make goal progress and higher relationship satisfaction, both of which, in turn, were associated with higher subjective well-being. Longitudinally, initial levels of goal congruence did not predict changes in goal progress and relationship quality over time. However, analysis of the individual goals indicated that people adjusted their goal pursuits based on the level of goal conflict between their own goals and their partners’ goals, such that people were more likely to stop pursuing or devalue goals that conflicted with their partners’ goals over time. Furthermore, the tendency to adjust goals over time was associated with increasing relationship commitment. The results of these studies show that conflict between relationship partners’ goals has important consequences for their relationship, goal progress, and personal well-being.

The current investigation compared the fit of three models of internalizing in middle childhood: (1) a unitary factor model, (2) a two-factor model corresponding to the DSM-IV Anxiety/Depression distinction, and (3) a two-factor model corresponding to the Fear/Distress distinction observed in structural studies of adult psychopathology (Krueger, 1999; Slade & Watson, 2006). Mothers of 344 children (50.6% female, mean age = 9.97, SD = .82) reported on childhood internalizing symptoms and personality traits. Confirmatory factor analyses revealed acceptable fit indices for all three models. The unitary factor model provided the most parsimonious fit to the data. Although the structural analyses suggested that internalizing subfactors were not differentiated in middle childhood, hierarchical regression analyses revealed that personality dimensions uniquely predicted fear and distress disorders. These results suggest that personality foreshadows later psychopathology structure before it is manifest at the symptom level.

Controversy exists over the validity of child Openness to Experience (OE), which is typically considered a major trait in adult personality models. In an effort to establish construct validity for child OE, data were collected for 346 children (51% girls) approximately 9–10 years of age (M = 9.92, SD = 0.83). Parents completed questionnaires about their children’s personality, temperament, and behavioral problems and competencies. Factor analyses of relevant personality and temperament facets revealed a robust and measurable OE factor made up of three facets: Intellect, Imagination, and Sensitivity. Evidence for convergent and discriminant validity was established via associations with other higher-order personality traits, behavioral problems, and behavioral competencies. The results underscore the importance of drawing from both temperament and personality literatures in attempts to establish construct validity for child trait domains as well as of moving beyond the higher-order domain and examining facet-level associations between OE and child behavior.

An individual`s eyes provide a wealth of information during social interactions. The present research investigates the social adjustment implications of one gaze behaviour, specifically, shared attention, which is the tendency to follow an interlocutor`s directed gaze to attend to the same object or location. Recent clinical research suggested that gaze control reflects the capacity to differentiate self from other at the attentional level, since patient populations with poor gaze control abilities (i.e., schizophrenic patients) were also found to exhibit difficulty in differentiating between the self and another agent. Four studies were conducted to examine whether flexible gaze following behavior, specifically the ability to inhibit gaze-following, when the situation warrants, would be positively linked with two markers of adaptive social functioning: sociocognitive abilities and self-close other(s) differentiation. Based on previous research that gaze cues linked to upright (but not inverted) faces trigger reflexive gaze following mechanisms, an upright face condition was used to assess social cueing mechanisms and an inverted face condition, as a control for non-social cueing mechanisms in a gaze control task with realistic (Study 2) and schematic faces (Studies 1, 3, and 4). Studies 1-4 showed that more flexible gaze following behavior predicted superior sociocognitive abilities, as indexed by higher capacity to infer the mental states of others in both young and older adults (Studies 1-3), as well as in clinical populations (i.e., Parkinson’s Disease [PD] patients, Study 4). Studies 2-4 further revealed that poorer gaze control predicted decreased self-close other differentiation in both younger and older adults. In Study 2, poorer gaze control performance characterized young adults from enmeshed family systems, which allow limited private space and emotional autonomy. In Studies 3 and 4, poorer gaze control predicted decreased cognitive-affective differentiation from one’s spouse and lower marital quality in healthy elderly couples (Study 3) and elderly couples, where one spouse had PD (Study 4). The present findings argue for the existence of a unified sociocognitive network, perpetually shaped by one’s interpersonal history, and which encompasses perceptual mechanisms, specialized for face and gaze processing and higher-order cognitive mechanisms, specialized for processing the meaning (s) of social environments.

The current dissertation employed a multi-method approach to examine gratitude as a mediator of the well-established relation between agreeableness and relationship quality. Study 1 examined this hypothesis in a sample of 158 same-sex best friend pair recruited from the Introductory Psychology subject pool at the University of Toronto, Mississauga. Each friend made self- and informant ratings of agreeableness and dispositional gratitude. Friends also made self-ratings of friendship quality. Structural equation model analyses with latent factors revealed that dispositional gratitude fully mediated the effects of agreeableness on friendship support, intimacy, and affection. Study 2 extended the findings of Study 1 by examining whether frequency of grateful affect was a more proximal mediator of the relation between agreeableness and marital quality. One hundred and ninety-seven family triads (student, mother and father) were recruited from the Introductory Psychology subject pools at the University of Toronto, St. George and Mississauga. Each member of the triad made self- and informant ratings of agreeableness, dispositional gratitude, frequency of grateful affect, and relationship quality. Structural equation model analyses with latent factors showed that frequency of spouses’ grateful affect fully mediated the effects of spouses’ agreeableness on marital support and intimacy and partially mediated the effect of agreeableness on marital companionship and affection. In sum, the findings of the current dissertation suggest that gratitude is one way in which agreeable individuals maintain good quality friendships and marital relationships. The implications of these results for current theories of gratitude as well as relationship research are discussed.
