False memory production: effects of self-consistent false information and motivated cognition

Brown, Martha 06 June 2008 (has links)
Remembrance of one's personal past and the development of false memories have recently received intense public scrutiny. Based upon self-schema (Markus, 1977) and self-verification (Swann, 1987) theories, two studies were conducted to investigate the hypothesis that a self-schema guides cognitive processing of self-relevant information and thereby influences the construction of a memory that includes false information, particularly more so if this information is self-schema consistent than inconsistent. Study 2 also investigated the hypothesis that the cognitive processing goal of understanding a negative outcome (motivated cognition) would interact with self-consistent expectations to enhance the likelihood that a false memory would be created. Self-schematic Type A and Type B individuals (only self-schematic Type A individuals participated in Study 2) participated in a team problem solving task (the to-be-remembered event) and returned a week later for a "questionnaire" session during which a narrative was read that contained self-consistent or self-discrepant false information. In both studies, chi-square analyses showed participants given self-consistent false information were more likely to report this information on a recall and a recognition test than were participants given self-discrepant false information. Study 2 included team performance feedback (failure or neutral), which was presented just before participants read the narrative containing the false information. The purpose of this procedure was to assess the moderating effect of motivated cognitive processes on the acceptance of self-consistent false information on memory. A loglinear analysis provided confirmation for the expected interaction. The following pattern was obtained for false recall and false self-description (description of team problem solving behavior using the false information trait adjectives): Consistent/failure > Consistent/neutral > Discrepant/neutral = Discrepant/failure. Unexpectedly, this pattern was not obtained on the recognition test data. These findings expand current understanding of processes that contribute to the production of a false memory and extend the traditional, post event false information paradigm. The results are discussed in the context of the false memory debate and future research directions are noted. / Ph. D.

The emergence of female leaders: the effects of self-monitoring, priming and task characteristics

Buchanan, Laurie Birch 14 August 2009 (has links)
Despite the growing number of women in the workforce, women still emerge as leaders in organizations less often than men. In order to understand this phenomenon, the current study explores the effects of self-monitoring, task characteristics, and priming on emergent male and female leaders. 160 high and low self-monitors performed one of two tasks (production or interpersonal task) in mixed sex groups of four, with a priming manipulation given to half of the groups. It was hypothesized and found that high self-monitors emerged more often as leaders than low self-monitors. The second hypothesis received partial support, as males emerged as leaders more often in a production task, but females did not emerge more often in an interpersonal task. Other hypotheses also received partial support, showing that high self-monitoring males emerged more often as leaders than females even during interpersonal tasks. Females did not emerge more often as leaders even if they were high self-monitors or if they were given a priming manipulation before completing a specified task. The implications of these findings and directions for future research are discussed. / Master of Science

Examining Gender Role Conflict in Strong Black Women's Romantic Relationships Using a Mixed Methods Approach

Gaskin-Cole, Gabriella Jacinta 07 1900 (has links)
The strong Black woman (SBW) schema is a racialized gender role characterized by emotional control, independence, and self-sacrifice. Little is known about how internalization of the SBW schema may influence Black women's romantic relationships. The current study explored the link between endorsement of the SBW schema and relationship flourishing through gender role conflict (the discrepancy between societally prescribed and personally enacted gender roles) and considered how these associations may vary based relationship type (queer or non-queer). One hundred eighty-eight Black women (Mage = 32.28, SD = 11.52 years) completed measures assessing SBW schema endorsement, gender role conflict (GRC), and relationship flourishing, as well as opened-ended questions about their romantic relationship. A mixed-method approach was used, and data was analyzed using a mediated moderation analysis utilizing PROCESS Macro and the thematic analysis method. Results revealed a significant negative correlation between the SBW schema and relationship flourishing. Additionally, GRC did not mediate the association between SBW schema and relationship flourishing, nor was that association moderated by relationship type. However, post-hoc analyses demonstrated that external GRC moderated the association between SBW schema and relationship flourishing. Themes revealed that participants experienced gender role conflict in their relationships both interpersonally (i.e., desire for boundaries, feeling disregarded, feeling prioritized, causing disagreements, and providing support) and intrapersonally (i.e., feeling unsupported, feeling emotionally and physically depleted, and feeling disconnected).

The Impact of Colour on Purchase Intention in the Cosmetics and Personal Care Industry : A Gender-Based Analysis

Thorstensson, Emilia, Ydreborg, Maja January 2024 (has links)
Abstract Background: The packaging design of a product, primarily the design element colour, affects purchase intention extensively. This has been stated in prior studies. However, whether colour has the same effect in the Swedish market has not been researched. Furthermore, there has been limited research on the difference between the genders' perception of gendered colours on product packaging and colours' effect on purchase intention in the Cosmetics and Personal care industry. Therefore, these elements are the focus of this research.   Purpose: This research aims to evaluate the effect of product packaging colour on Swedish residents' purchase intention in the Cosmetics and Personal Care industry. Furthermore, the relationship between gendered colours on product packaging and purchase intention will be analysed, comparing females and males.   Method: This study is deductive research, and it is based on a positivism paradigm. It uses a quantitative approach of gathering data through an online questionnaire. The sample consisted of 194 Swedish residents gathered through convenience sampling. Moreover, the data was analysed using Cronbach alpha coefficient, Spearman's rank correlation coefficient and Ordered logistic regression to test the hypotheses.    Findings: The theoretical framework identified a research gap concerning the impact of product packaging colours on purchase intention and how gender-specific packaging colours affect males and females differently. Based on the existing literature, five hypotheses were formulated. The findings confirmed that product packaging colours for all Swedish residents, had a significant positive influence on purchase intention, leading to the acceptance of H1. Moreover, both males and females demonstrated a significant positive effect on purchase intention when exposed to packaging colours associated with their respective genders, resulting in the acceptance of H2 and H4. However, both genders demonstrated a non-significant effect on purchase intention when exposed to packaging colours associated with the opposite gender, leading to the rejection of H3 and H5.   Conclusion: The results show that product packaging colour has a positive effect on purchase intention among Swedish residents. Moreover, it shows that the Gender Schema theory is still relevant in today's society, which shows contribution to theory. Further, marketers should continue to use gendered colours in their product packaging.

Different Bodies, Different Selves: The Role of Physical Disability in the Formation of Personal Identity

Anderson, John 01 January 2006 (has links)
The variables that contribute to the acquisition of personal identity are many, and the interactions that occur before someone realizes "I am ... " are complex, to say the least. The process of ' identification' that is, the aforementioned acquisition of the self is not a static process that is the same for each person. Although some similar patterns of existence may occur, it is ultimately a unique occurrence. I propose that in the 'construction of the self that there are three broad facets of existence that should be addressed in answering questions concerning personal identity the physiological, the psychological, and the social. Each of these factors contributes to the process of becoming that is personal identity. This is in line with modem psychological models. The present work seeks to bring to light some of these facets of personal identity in general. More than this however, an attempt will be made to examine some of the ways in which physical disability can affect one's sense of personal narrative that is woven into "Who I am and whom I wish to be." In the course of this work several topics will surface. First an emphasis will be placed on the physical expressions and ' limitations' of the body as an extension into space. The concept of the "body schema" will be explained here to illustrate the ways in which the body is integrated into the self. Next, the psychological effects of physical disability will be addressed with a focus toward the reconstruction of mental representations of the 'normal' body and the resultant effects of this reconstruction. Here, the "body image" of the disabled individual will be discussed using data from

Who Carries the Burden of Strength? The Impact of Colorism on Perceptions of Strong Black Women

Jean-Ceide, Cassandre Jennie 05 1900 (has links)
Using intersectionality as a guiding framework, the current study examined how gendered and racialized perceptions of Black women as "strong Black women" may be shaped by colorism. This experimental study sampled 314 Black and White participants from the community. Participants were presented with a vignette that described a Black woman coping with workplace stress in one of two ways, one congruent with strong Black womanhood (emotional restriction) and one incongruent with strong Black womanhood (emotional vulnerability), alongside the image of a light skin or dark skin Black woman. Then, participants were asked to rate how "strong" they perceived the woman in the vignette to be. A factorial ANCOVA was conducted to test how perceptions of the woman in the vignette varied based on her emotional response to workplace stress and skin tone, while controlling for perceptions of likability and competence. As hypothesized, we observed that participants perceived the woman responding to workplace stress with emotional restriction as stronger than the women who responded with emotional vulnerability. However, skin tone, nor the interaction between emotional response and skin tone had a bearing on participants' perceptions. There were also no differences in perceptions based on participant race. Through its intersectional framing, this study challenges scholars and practitioners to consider how the interplay between racism, sexism, and colorism shapes how Black women are seen by others and, in turn, how they may see themselves as strong Black women. Implications of the findings, limitations, and future directions are discussed.

Adaptation du modèle de la Construction-Intégration de Kintsch à la compréhension des énoncés et à la résolution des problèmes arithmétiques complexes / Understanding and solving complex word arithmetic problems : adaptation of the Construction-Integration model of Kintsch

Lebreton, Olivier 21 January 2011 (has links)
Cette recherche a pour objet la compréhension des énoncés de problèmes arithmétiques complexes et leur résolution. Les problèmes complexes choisis combinent des problèmes simples de types Changement et Combinaison. Ce travail s’appuie sur le modèle de la Construction-Intégration de Kintsch. Les résultats montrent qu’il existe une relation entre le niveau d’expertise en compréhension de textes narratifs et la résolution des problèmes arithmétiques complexes. Comprendre un texte narratif ou un énoncé de problème complexe exige de la part des lecteurs la construction d’un réseau propositionnel hiérarchisé et les résultats suggèrent, entre autres, une sensibilité des élèves aux propositions textuelles et aux ellipses contenues dans les textes. La formation des macropropositions est un processus fondamental et les résultats montrent une relation entre le nombre d’objets contenus dans les énoncés de problème et la procédure préférentiellement choisie par les élèves. Ils suggèrent d’une part, la mise en oeuvre du processus de catégorisation au cours du processus de compréhension et d’autre part, l’affaiblissement des liaisons entre les macropropositions élaborées et le schéma de problème Parties-Tout qui leur sont liés. D’un point de vue pédagogique, les résultats montrent que les questions relatives à l’activation d’une part des concepts superordonnés et d’autre part des schémas de problèmes Parties-Tout ne sont pas à privilégier pour aider les élèves. Finalement, les connaissances du lecteur sont essentielles à la compréhension. Cet élément est confirmé ici et la compréhension des problèmes complexes nécessite des connaissances solides relativement aux problèmes arithmétiques simples. / This research deals with text comprehension processes and complex arithmetic word problems resolution by 9-10 years old children in Reunion Island based upon the CI model of Kintsch. The complex word arithmetic problems used in this research are a combination of Change simple problems and Combine simple problems. The results show a relation between subject’s level of expertise in narrative texts comprehension and complex arithmetic word problems resolution. In order to understand a narrative text or to resolve a complex arithmetic word problem, subjects have to elaborate a coherent hierarchical propositional network : bridging inferences and macropropositions are involved to achieve complex arithmetic word problems resolution too. More precisely, the results suggest children are sensitive to the number of propositions and to the ellipsises. Macropropositions formation is an integral process of reading. The results show a relation between number of objects in complex arithmetic problems and procedure naturally used by children to solve them. They suggest on the one hand, categorization processes are an integral part of reading and on the other hand, some links between macropropositions and arithmetic hypothesis become weaker. Consequently, questions about superordinate concepts and arithmetic hypothesis attached to them are not helpul to resolve complex arithmetic word problems. Finally, reader’s knowlegde is a key element of comprehension processes and to achieve complex arithmetic word problems, problem schemata about simple arithmetic word problems are crucial. The results show a relation between subject’s level of expertise in simple arithmetic word problems and complex arithmetic word problems resolution.

This is a challenging problem, since the same concept is often represented by disparate elements in the schemas. The traditional instances of this problem involved a pair of schemas to be matched. However, recently there has been a increasing interest in matching several related schemas at once, a problem known as Schema Matching Networks, where the goal is to identify elements from several schemas that correspond to a single concept. We propose a family of methods for schema matching networks based on machine learning, which proved to be a competitive alternative for the traditional matching problem in several domains. To overcome the issue of requiring a large amount of training data, we also propose a bootstrapping procedure to automatically generate training data. In addition, we leverage constraints that arise in network scenarios to improve the quality of this data. We also propose a strategy for receiving user feedback to assert some of the matchings generated, and, relying on this feedback, improving the quality of the final result. Our experiments show that our methods can outperform baselines reaching F1-score up to 0.83. / Casamento de Esquemas é a tarefa de encontrar correpondências entre elementos de diferentes esquemas de bancos de dados. É um problema desafiador, uma vez que o mesmo conceito geralmente é representado de maneiras distintas nos esquemas.Tradicionalmente, a tarefa envolve um par de esquemas a serem mapeados. Entretanto, houve um crescimento na necessidade de mapear vários esquemas ao mesmo tempo, tarefa conhecida como Casamento de Esquemas em Rede, onde o objetivo é identificar elementos de vários esquemas que correspondem ao mesmo conceito. Este trabalho propõe uma famı́lia de métodos para o problema do casamento de esquemas em rede baseados em aprendizagem de máquina, que provou ser uma alternativa viável para o problema do casamento tradicional em diversos domı́nios. Para superar obstáculo de obter bastantes instâncias de treino, também é proposta uma técnica de bootstrapping para gerar treino automático. Além disso, o trabalho considera restrições de integridade que ajudam a nortear o processo de casamento em rede.

兒童故事基模發展與電視卡通暴力訊息解讀之關聯性研究 / Children's story schema development and its relation to decoding television violent cartoon

李秀美, Li, Hsiu Mei Unknown Date (has links)
兒童的電視暴力行為模仿是存在的,常人由個人經驗和媒體的顯著個案報導對此現象建立表象的印證;而學者透過研究也證實電視暴力具有不良示範作用,和閱聽人─尤其是兒童─日常生活的攻擊行為脫離不了關係。但學界卻忽視了兒童的認知節目能力與電視暴力訊息的互動關係:兒童看過有暴力訊息的節目後,電視暴力訊息在兒童腦海裡會留下什麼印象;並進一步告訴常人如何扼止這些印象可能引起的不當後果。   本研究企圖應用故事基模理論於電視暴力訊息的研究,探討電視暴力訊息如何透過故事基模的運作,在兒童腦海中留下何種的印象。研究方法為場地實驗法配合問卷調查及深度訪談等多重方法設計。   研究發現,兒童的電視故事基模具有層級效果,愈上層回憶愈抽象。電視暴力訊息的高低和呈現方式,對兒童組織故事的方式沒有顯著的影響;但視覺呈現的高暴力訊息會使兒童對故事產生較多的推論;如果故事一開始就出現大量的高暴力畫面,則能強化兒童對故事開始情節的記憶。年齡和先備知識是有力的解釋變項。年長的、先備知識豐富的兒童電視故事基模較強,回憶數多、理解高、偏差少、推論多,顯見故事基模的形成一方面是自然的成熟因素,同時也受環境經驗因素的作用。   然而年幼兒童對於最易產生暴力訊息的反應和企圖事件的回憶數及詳細層次,與年長兒童無顯著差異,但對行為後果(施暴下場)記憶較簡略,可能因此產生施暴並無不可的解禁心理。此外,父母教育程度高、社會成績好、電視知識豐富的兒童故事基模亦較佳,尤其是男生可能因興趣使然,對本研究的故事記憶更好,且詳細記得反應和企圖事件。   根據研究發現,本研究建議未來電視暴力研究觀察互動情形、加強實驗設計、進行特定對象研究、進行長期研究;並對電視節目製作者提出加強故事張力減少暴力情節、不得不保留的暴力情節應淡化處理、發展電視識讀材料等實質建議。 / This study applied story schema theory to understand how children decoded the violent messages in television cartoon by a multi-method design. in-depth interviews were conducts with 60 subjects immediated after watching a TV cartoon with different violent level and media presented in a experiment. The same interviews were conducts again after one week.   The study demonstrate the 'effect level'in childern's TV story schema and find the top recall level is more abstract. No significant relationship between story schema and violence decoding were found, but visual-presented high violence may increase inferene and enhance memory on the beginning episode. These results correlated closely with age and story-relevant previous knowledge. Finally, the author make some suggestions to TV program producedr.

Clinical psychology : development of measures for schema therapy

Louis, John Philip January 2018 (has links)
Schema therapy is a leading contemporary approach to treating mental illness. The therapy integrally uses self-report measures of negative schemas (“long lasting patterns of emotions, cognitions and memories”), and the negative parenting patterns that are linked to the development of these schemas. However, the negative parenting measures are insufficient, and there are no corresponding measures of positive schemas or positive parenting patterns. Study 1 focused on the development of a measure for positive schemas, the Young Positive Schema Questionnaire (YPSQ). Study 2 focused on the development of a measure for positive parenting patterns, the Positive Parenting Schema Inventory (PPSI). Finally, Study 3 empirically showed that the subscales of the Young Parenting Inventory (YPI) were not robust, and it provided a revised alternative (YPI-R2). For all three studies combined, community samples (n = 204 to 628) were collected from five countries in Asia (India, Indonesia, Malaysia, Singapore, and the Philippines) as well as the United States. The factor structure of the three instruments (the YPSQ, PPSI and YPI-R2) was stable in both Eastern and Western samples (in multigroup confirmatory factor analysis). All three scales showed prediction of mental health over and above what was possible with previous measures (incremental validity). The scales were not simply proxies for previously measured constructs (divergent validity). These scales also demonstrated significant associations with other established measures of parenting (construct validity). They also showed associations with negative schemas, well-being and ill-being (convergent validity). This thesis provides the tools needed to include a focus on positive as well as negative schemas and parenting patterns in both research and clinical practice. It also shows the benefits of so doing.
