What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul

Theses and Dissertations (Comprehensive)

Memory is undoubtedly one of the most important processes of human cognition. A long line of research suggests that recognition relies on the assessment of two explicit memory phenomena: familiarity and recollection. Researchers who support the Dual Process Signal Detection (DPSD) model of recognition memory link the FN400 component (a negative ERP deflection peaking around 400 ms at frontal electrodes) with familiarity; however, it is currently unclear whether the FN400 reflects familiarity or implicit memory. Three event-related potentials (ERP) studies were conducted to determine whether implicit memory plays a role in setting up encoding strategies, and how these encoding strategies …

Can "Slacktivism" Work? Perceived Power Differences Moderate The Relationship Between Social Media Activism And Collective Action Intentions Through Positive Affect, Mindi D. Foster, Eden J.V. Hennessey, Benjamin T. Blankenship, Abigail Stewart

Psychology Faculty Publications

We argue that the often-used critique of social media activism as merely a ‘feel-good’ mechanism can be countered by conceptualizing social media activism as a necessary type of collective action (i.e., consensus mobilization), incorporating theory on the benefits of positive feelings for activism, and by examining how power may affect these relationships. Women from two different samples (MTurk and university) were randomly assigned to recall a high- versus low-power experience, view real-world events of sexism, and then complete questionnaires assessing endorsement of social media activism, positive affect, and collective action intentions. A dual moderated mediation analyses at the second stage …

Processing Youth Adventure Wellness Experiences: Poetic Representations Of Youth’S Peace Bus Experiences, Ty Th Nguyen

Theses and Dissertations (Comprehensive)

This narrative inquiry explored how youth are processing their Peace Bus program experiences two and a half years after program completion. The purpose was to gain an understanding of (1) what program components the participants reflect on, (2) how they conceptualize their program experiences, and (3) what factors contribute to their reflection processes. This research sought to address the gap in literature where little is understood about the ongoing experiences of program participants of adventure wellness programs and the processes that lead to positive changes. As the researcher, I conducted a qualitative study using narrative inquiry and poetic representation methods. …

Second Language Acquisition And Acculturation Differences Between Immigrants And Refugees, Ali Jasemi

Theses and Dissertations (Comprehensive)

The main difference between refugees and immigrants lies in the reason for their migration. Economic immigrants migrate to other countries voluntarily, while refugees are forced to leave their countries due to fear of death or persecution (UNHCR, 2018). Such fears may lead to psychological trauma among refugees. Research has shown that the presence of trauma can negatively impact language learning (Iversen, Sveaass, & Morken, 2014), which may have important implications for both second language (L2) acquisition and acculturation, particularly in refugees. In addition, strong linguistic abilities in a first language (L1) may be beneficial to acquire other languages (Cook, 2003). …

"Use It Or Lose It": How Online Activism Moderates The Protective Properties Of Gender Identity For Well-Being, Mindi D. Foster

Psychology Faculty Publications

Regardless of criticisms that online activism does nothing but increase positive feelings, there is merit to understanding the role of online activism for well-being. This research sought to integrate two separate but complimentary lines of research (the well-being effects of activism and social identity) by suggesting that online activism may enhance the ability of social identity to protect against the negative well-being consequences of pervasive discrimination. Three studies, each with different operational definitions of online activism, showed a similar pattern: online activism enhanced the relationship between gender identity and well-being. Consistent with theory on activism’s role as a dynamic predictor …

Exploratory Study Of The Use Of Community Treatment Orders With Clients Of An Ontario Act Team, Magnus Mfoafo-M'Carthy, Cara Grosset, Carol Stalker, Irene Dullaart, Linda Mccoll Dr.

Lyle S. Hallman Social Work Faculty Publications

Community Treatment Orders (CTOs) have raised questions about coercion, lack of autonomy, and effectiveness in reducing hospitalizations and improving service users’ quality of life. This study examined the experiences of clients and clinicians when CTOs are used in combination with Assertive Community Treatment (ACT) in a recovery oriented approach. Eleven clients who were or had previously been on a CTO and eight ACT clinicians were interviewed. Although most clients had negative feelings about CTOs, some acknowledged their lives had improved. Clinicians reported that the decision to employ a CTO is sometimes debated within the team but they agreed that combining …

The Walk-In Counselling Model Of Service Delivery: Who Benefits Most?, Manuel Riemer, Carol A. Stalker, Livia D. Dittmer, Cheryl-Anne Cait, Susan Horton, Narges Kermany, Jocelyn Booton

Psychology Faculty Publications

The walk-in counselling (WIC) model of service delivery has been found to reduce psychological distress more quickly than a traditional model of service delivery involving a wait list. A question remains, however, as to the relative benefit of the WIC model for different client groups. The present study uses graphical inspection and multilevel modeling to conduct moderator analyses comparing two agencies, one with a WIC clinic and the other with a traditional wait list approach, and their relative impact on psychological distress. Key findings regarding the differential benefits for different types of presenting problems as well as clients at different …

Picture This: Using Photo-Research Exhibits As Science Outreach, Eden J.V. Hennessey, Mindi D. Foster, Shohini Ghose

Psychology Faculty Publications

Is a picture worth a thousand words? This paper discusses a unique science outreach initiative–provocative photo-research exhibits on sexism in science.

Gender imbalance in science, technology, engineering, and math (STEM) is not only a concern from a social justice perspective, but also has negative consequences for scientific innovation and the economy, given that lack of workplace gender diversity is associated with lower revenue and returns. Science outreach (i.e., public outreach by scientists) could be particularly impactful in Waterloo, Ontario – a region known as ‘Canada’s Silicon Valley’ that contributes over $30-billion annually to the global economy. Portraying complex social issues …

Prosecutors’ Perceptions On Questioning Children About Repeated Abuse, Kim Roberts, Martine Powell, Kimberlee S. Burrows, Sonja P. Brubacher

Psychology Faculty Publications

The purpose of the present study was to elicit guidance from prosecutors across Australia on questioning children about repeated events. Two focus groups were conducted; the first sought broad feedback concerning questioning children about repeated events. The second focused more specifically on eliciting feedback about techniques for aiding children in describing specific instances of repeated events. These techniques were derived either from empirical research, best practice interview guidelines, or both. Data from both focus groups were compiled because themes were highly similar. Thematic analysis of the focus group discussions revealed three broad themes in prosecutors’ perceptions about questioning children about …

Auditory Erp Differences Across A Continuum Of Psychotic Symptoms In Non-Clinical Population, Anaya Rehman

Theses and Dissertations (Comprehensive)

Psychosis is a term given to a mental state described as a loss of contact with the real world. The aim of this thesis was to examine early non-specific psychotic experiences in a healthy population by means of two self-report screening tools: Prime Screen and Youth Psychosis At-Risk Questionnaire-Brief, and place individuals on a psychosis continuum. Across this psychosis continuum, three event related potential (ERP) components were assessed: P300, Mismatch Negativity and N100. There is evidence that P300 and mismatch negativity amplitudes diminish in individuals with psychosis. Similarly, impaired N100 amplitude suppression (increased N100 amplitudes) during vocalization has been observed …

Social Problems, Biomedical Answers? How Causes Of Social Problems Affect Choice Of Solutions, Bianca C. Dreyer

Theses and Dissertations (Comprehensive)

With rapid advances in behavioural genetics, scientists are identifying an increasing array of genetic influences on human behaviour. Public misconceptions about the function of genes often lead to the oversimplification of the role of genes in behaviour (Dar-Nimrod & Heine, 2011). To date, no study has systematically investigated whether simply learning about genetic causes of behaviour affects people’s preferred solutions to problematic behaviours. The present research program includes three studies that were designed to examine the psychological effects of exposure to genetic etiology for problematic behaviour, in particular aggression, and investigated how this information influences endorsement of solutions, rating of …

Tweeting About Sexism: The Well-Being Benefits Of A Social Media Collective Action., Mindi D. Foster

Psychology Faculty Publications

Although collective action has psychological benefits in non-gendered contexts (e.g., Drury et al., 2005), the benefits for women taking action against gender discrimination are unclear. This study examined how a popular, yet unexplored potential form of collective action, namely tweeting about sexism, affects women’s well-being. Women read about sexism and were randomly assigned to tweet, or to one of three control groups. Content analyses showed tweets exhibited collective intent and action. Analyses of linguistic markers suggested public tweeters used more cognitive complexity in their language than private tweeters. Profile analyses showed that compared to controls, only public tweeters showed decreasing …

The Relationship Between Collective Action And Well-Being And Its Moderators: Pervasiveness Of Discrimination And Dimensions Of Action, Mindi D. Foster

Psychology Faculty Publications

Given the negative impact of perceiving gender discrimination on health (e.g., Pascoe & Smart Richman, 2009), there is a need to develop interventions to attenuate this effect; collective action may be one such intervention. Study 1 (N = 185) used an experimental paradigm to investigate whether undergraduate women in Waterloo, Ontario, Canada perceived pervasiveness of discrimination would interact with their collective action-taking to predict negative mood and well-being. Results showed that among those perceiving pervasive gender discrimination, informing friends/family and informing the media led to greater well-being than doing nothing, whereas among those perceiving gender discrimination as isolated, doing nothing …

Everyday Confrontation Of Discrimination: The Well-Being Costs And Benefits To Women Over Time., Mindi D. Foster

Psychology Faculty Publications

Taking action against discrimination has positive consequences for well-being (e.g., Cocking & Drury, 2004) but most of this research has focused on collective actions and has used methodologies assessing one point in time. This study therefore used a diary methodology to examine how women’s everyday confrontations of discrimination would affect measures of subjective and psychological well-being, and how these relationships would change over time. In a 28-day online diary study, women indicated their daily experience of discrimination, described their response, and completed measures of well-being. Results showed that at the beginning of the study, using indirect confrontation predicted greater well-being …

How Do Interviewers And Children Discuss Individual Occurrences Of Alleged Repeated Abuse In Forensic Interviews?, Sonja P. Brubacher, Lindsay C. Malloy, Michael E. Lamb, Kim Roberts

Psychology Faculty Publications

Police interviews (n = 97) with 5- to 13-year-olds alleging multiple incidents of sexual abuse were examined to determine how interviewers elicited and children recounted specific instances of abuse. Coders assessed the labels for individual occurrences that arose in interviews, recording who generated them, how they were used, and other devices to aid particularisation such as the use of episodic and generic language. Interviewers used significantly more temporal labels than did children. With age, children were more likely to generate labels themselves, but most children generated at least one label. In 66% of the cases, interviewers ignored or replaced …

Perceiving Pervasive Discrimination Over Time: Implications For Coping, Mindi D. Foster

Psychology Faculty Publications

This study suggests the effects of perceived pervasiveness may be dynamic over time. The hypothesis was that participants who perceived discrimination to be highly pervasive would initially be more likely to engage in inactive coping strategies than those who perceived low pervasiveness. However, those who continued to perceive high pervasiveness over time would ultimately show greater evidence of using active strategies than those perceiving low pervasiveness. Using a 28-day diary, women and ethnic minorities described their daily experiences of discrimination and indicated their appraisals of its pervasiveness as well as their coping strategies. Results showed that participants who initially perceived …

The Dynamic Nature Of Coping With Gender Discrimination: Appraisals, Strategies And Well-Being Over Time, Mindi D. Foster

Psychology Faculty Publications

Female introductory psychology students at a Canadian university (N = 31) participated in a lab simulation of discrimination, completed coping and well-being measures and then an online survey of well-being one year later. Expectations were that active (inactive) coping would initially be related to decreased (increased) well-being. A reverse pattern was expected for relationships between coping and well-being one year later. Results showed that among those perceiving high pervasive discrimination, active and inactive coping was related to decreased well-being immediately after the discrimination was portrayed, but among those perceiving low pervasiveness inactive coping was related to increased well-being. One year …

The Tactile Motion Aftereffect, Peggy Joanne Planetta

Theses and Dissertations (Comprehensive)

The tactile motion aftereffect (tMAE) is a perceptual phenomenon in which illusory motion is reported following adaptation to a unidirectionally moving tactile stimulus. Unlike its visual counterpart, relatively little is known about the tMAE. For that reason, the purpose of this dissertation was to gain a better understanding of the tMAE using both psychophysical and neuroimaging techniques. In a series of five experiments the skin was adapted using a plastic cylinder with a square-wave patterned surface. Chapter 2 consists of two experiments, both of which adapted the glabrous surface of the right hand. Experiment 1 showed that the prevalence, duration, …

List Composition Effects For Masked Semantic Primes: Evidence Inconsistent With Activation Accounts, Jennifer C. Major

Theses and Dissertations (Comprehensive)

Priming is the benefit that an event receives when its processing has been preceded by the processing of a related or identical event. Context effects on priming are evident when priming changes as a function of some feature of experimental trials. The most commonly explored context effect is that of relatedness proportion (RP), where it has often been shown that the magnitude of priming (semantic or repetition) is directly related to the proportion of related trials: Increasing the related trials results in greater priming. Although previously thought to depend on strategic processing, recent evidence of context effects from designs using …

Particularisation Of Child Abuse Offences: Common Problems When Questioning Child Witnesses, Martine B. Powell, Kim P. Roberts, Belinda Guadagno

Psychology Faculty Publications

Prosecuting child abusers is often difficult due to lack of particularising details. Two possible ways of addressing this difficulty are: (a) to change the justice system to better serve prosecution for repeated offences (i.e., allow generic testimony), and (b) to bolster children's testimony. As this article has illustrated, there is still considerable potential for increasing (b). Given the low prosecution rates of child abuse offences, the need for exceptional interviewer training programs coupled with resources for ongoing supervision is now critical. While there have been some major improvements in child witness investigative interviews over the past two decades, there are …

Responding To Discrimination As A Function Of Meritocracy Beliefs And Personal Experiences: Testing The Model Of Shattered Assumptions, Mindi D. Foster, Lisa Sloto, Richard Ruby

Psychology Faculty Publications

We examined whether the model of shattered assumptions (Janoff-Bulman, 1992) could be applied to the reactions of victims of discrimination. Consistent with this model, it was hypothesized that those whose positive world assumptions are inconsistent with their negative experiences of discrimination would report more negative responses than those whose world assumptions match their experience. Disadvantaged group (both gender and ethnicity) members’ responses to discrimination (self-esteem, collective action, intergroup anxiety) were predicted from their meritocracy beliefs and personal experiences of discrimination. Regression analyses showed a significant interaction between meritocracy beliefs and personal discrimination such that among those who reported personal discrimination, …

A Narrative Approach To The Evaluation Of Supportive Housing: Stories Of Homeless People Who Have Experienced Serious Mental Illness, Geoffrey Nelson, Juanne Nancarrow Clarke, Angela Febbraro, Maria Hatzipantelis

Psychology Faculty Publications

We present the findings of a narrative approach to the evaluation of supportive housing for formerly homeless people who have experienced serious mental illness. According to the accounts of 11 men and 9 women, their youth and adult years were piled with personal problems, troubled relationships, and a lack of adequate social resources. Since entering supportive housing, participants noted more stability in their lives and the beginning of journeys to recover positive personal identities, restore or develop new supportive relationships, and reclaim resources vital to leading lives with dignity and meaning. The findings add to the literature on housing interventions …

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 …

When The Advantaged Become Disadvantaged: Men’S And Women’S Actions Against Gender Discrimination, Mindi D. Foster, Stacey Arnt, Jill Honloka

Psychology Faculty Publications

Intergroup theories suggest that different social identities will either discourage or encourage the taking of action against discrimination (Bartky, 1977; Jost & Banaji, 1994). However, research (e.g., Branscombe, 1998) has shown that discrimination is a less negative experience for men than for women. As such, it is possible that men may take greater action than women, regardless of identity. However, men’s responses to their perceived disadvantage has not yet been tested. Among those induced to ascribe to a gendered stereotype identity, men endorsed more action than women did.Among those induced to ascribe to an identity based on a gendered social …

The Role Of Hardiness In Moderating The Relationship Between Global/Specific Attributions And Actions Against Discrimination, Mindi D. Foster, Kenneth L. Dion

Psychology Faculty Publications

In this study, we proposed that individual differences in hardiness may moderate the relationship between global attributions and actions against discrimination. Specifically, global attributions were expected to predict decreased endorsement of actions to combat discrimination among low hardy women. In contrast, global attributions were expected to predict increased endorsement of actions among high hardy women. High and low hardy women were exposed to a laboratory situation of discrimination, and their attributions for, and responses to, discrimination were then assessed. Results showed the expected interaction, but in the opposite direction: among low hardy women, global attributions predicted stronger endorsement of action.Among …

Minimizing The Pervasiveness Of Women’S Personal Experiences Of Gender Discrimination, Mindi D. Foster, Lydia C. Jackson, Ryan Hartmann, Shannon Woulfe

Psychology Faculty Publications

Given the Rejection-Identification Model (Branscombe, et al., 1999) which shows that perceiving discrimination to be pervasive is a negative experience, it was suggested that there would be conditions under which women would instead minimize the pervasiveness of discrimination. Study 1 (N = 91) showed that when women envisioned themselves in a situation of academic discrimination, they defined it as pervasive but when they experienced a similar laboratory simulation of academic discrimination, its pervasiveness was minimized. Study 2 (N = 159) showed that women who envisioned themselves experiencing discrimination minimized its pervasiveness more so than women reading about discrimination …

Dispositional Hardiness And Women’S Well-Being Relating To Gender Discrimination: The Role Of Minimization, Mindi D. Foster, Kenneth L. Dion

Psychology Faculty Publications

Three studies examined whether personality-based hardiness would be associated with mental health benefits in contexts of gender discrimination. Hardy women encountering both a laboratory simulation and a hypothetical scenario of discrimination showed greater self-esteem and less negative affect than low hardy women. However, these benefits were mediated by the use of specific attributions, suggesting that the well-being in hardy women may have been achieved through minimizing the pervasiveness of discrimination. Study three showed this mediation pattern occurred only for participants exposed to higher threat scenarios versus lower threat scenarios of discrimination. Thus, minimizing the pervasiveness of discrimination may have been …

The Motivational Quality Of Global Attributions In Hypothetical And Experienced Situations Of Gender Discrimination, Mindi D. Foster

Psychology Faculty Publications

Traditionally, global attributions have been thought to reduce instrumental behavior aimed at resolving negative events. However, the present research shows global attributions for gender discrimination are related to taking action against unfair treatment. In Study 1, women ( N = 157) completed a questionnaire assessing attributions for hypothetical scenarios of discrimination and collective responses to discrimination. In Study 2, women ( N = 79) were placed into a laboratory situation of discrimination and asked to indicate their attributions for and responses to their unfair treatment. In both studies, hierarchical regression analyses showed that global attributions were related to both individual …

Positive And Negative Responses To Personal Discrimination: Does Coping Make A Difference?, Mindi D. Foster

Psychology Faculty Publications

Although psychological research has found that perceiving personal discrimination is associated with negative psychological symptoms, group consciousness theories suggest that perceiving personal discrimination can be empowering. To attempt to reconcile these presumably opposing findings, the present study suggested that how one copes with perceiving personal discrimination may better predict whether the outcomes are negative or positive than the perception of personal discrimination alone. American female university students ( N = 262) completed a questionnaire assessing their perceptions of personal discrimination, psychological symptoms and psychosocial behaviors. A series of hierarchical regression analyses indicated that coping mechanisms predicted psychosocial behaviors over and …

Utilization Of Global Attributions In Recognizing And Responding To Gender Discrimination Among College Women, Mindi D. Foster

Psychology Faculty Publications

Although learned helplessness theories suggest that global attributions for gender discrimination may serve to promote feelings of helplessness about responding to discrimination, group consciousness theories suggest they may instead be a precursor to enhancing collective actions against discrimination.

To examine this theoretical discrepancy, college women completed measures of attributions for gender discrimination, political consciousness (as measured by common fate), participation in collective action, and helplessness behavior among college women. To examine the unique role of global attributions, participants were included if they made external and unstable attributions for discrimination (N = 231). Structural equation modeling showed hat recognizing discrimination occurs …
