Predicting The Adoption Of Password Managers: A Tale Of Two Samples, Shelia Kennison, D. Eric Chan-Tin

Computer Science: Faculty Publications and Other Works

Using weak passwords and re-using passwords can make one vulnerable to cybersecurity breaches. Cybersecurity experts recommend the adoption of password managers (PMs), as they generate and store strong passwords for all accounts. Prior research has shown that few people adopt PMs. Our research examined PM adoption in a sample of 221 undergraduates from psychology courses and a sample of 278 MTurk workers. We hypothesized that PM adoption could be predicted using a small set of user characteristics (i.e., gender, age, Big Five personality traits, number of devices used, frequency of using social media, and cybersecurity knowledge). The results showed that …

Exploring The Role(S) Of Trait Emotional Intelligence & Personality In Help-Seeking Behaviour Among Undergraduate Students, Nikola Cuvalo

Electronic Thesis and Dissertation Repository

Trait emotional intelligence (EI) and the Big Five personality factors represent promising constructs in the individual differences literature that have been investigated in relation to help-seeking behaviour. This quantitative work explores the relationship between individual differences in trait EI, personality, and attitudes toward – as well as future intentions to engage in – help-seeking behaviour among undergraduate students at Western University. Stepwise regression modelling was used to determine which dimensions of personality and trait EI best predicted help-seeking outcomes and whether attitudes toward help-seeking predicted intentions to seek help from university-provided mental health sources. Resultsindicated that several individual facets of …

Individual Differences In Social Play Behaviour Predict Alcohol Intake And Control Over Alcohol Seeking In Rats, Heidi M. B. Lesscher, E. J. Marijke Achterberg, Stephen M. Siviy, Louk J. M. J. Vanderschuren

Psychology Faculty Publications

Rationale

Social play behaviour is a rewarding social activity displayed by young mammals, thought to be important for the development of brain and behaviour. Indeed, disruptions of social play behaviour in rodents have been associated with cognitive deficits and augmented sensitivity to self-administration of substances of abuse, including alcohol, later in life. However, the relation between social development and loss of control over substance use, a key characteristic of substance use disorders including alcohol use disorder (AUD), has not been investigated. Moreover, it remains unknown how inherent differences in playfulness relate to differences in the sensitivity to substance use and …

Understanding Individual Differences Within Large-Scale Brain Networks Across Cognitive Contexts, Katherine L. Bottenhorn

FIU Electronic Theses and Dissertations

Historically, human neuroimaging has studied brain regions “activated” during behavior and how they differ between groups of people. This approach has improved our understanding of healthy and disordered brain function, but has two key shortcomings. First, focusing on brain activation restricts how we understand the brain, ignoring vital, behind-the-scenes processing. In the past decade, the focus has shifted to communication between brain regions, or connectivity, revealing networks that exhibit subtle, consistent differences across behaviors and diagnoses. Without activation-focused research’s constraints, connectivity-focused neuroimaging research more comprehensively assesses brain function. Second, focusing on group differences ignores substantial within-group heterogeneity and often imposes …

The Role Of Cognitive Load And Individual Differences When Interpreting Human-Resource Data Visualizations, Zachary Hesson

University Honors Theses

Data visualizations (e.g., bar graph, dashboard) can be used as decision-support and storytelling tools that aid users’ interpretation of sometimes complex information, including within the human resource management (HRM) context. As HRM evolves towards implementing more data-informed decisions, it is important to understand how users interpret data visualizations. The aims of this thesis are to (a) identify whether cognitive load affects the amount of time users spend arriving forming and interpretation and the accuracy of their interpretations, and (b) to evaluate whether cognitive load moderates the association between individual-difference variables and interpretation time and accuracy. The individual differences that are …

Intense News : The Role Of Emotion In The Perception Of (Fake) News, Allison Marie Wilck

Legacy Theses & Dissertations (2009 - 2024)

Today’s widespread access to the internet and social media platforms has vastly enhanced our ability to communicate stories and ideas. This includes the dissemination of both accurate and false information. Since 2016, the popularity of the term ‘fake news’ has skyrocketed, referring to the circulation of claims that were created with the intention to spread inaccurate information. Because of its inherent falseness yet widespread presence, fake news provides a rich outlet for exploring the variables that cause a claim to appear believable. Recent empirical explorations have well-established the presence of emotional information as a hindrance to overcoming susceptibility to misinformation …

The Effect Of Individual Difference On The Continued Use Of False Information: Intelligence And Personality, Brandy F. Mcneil

Brescia Psychology Undergraduate Honours Theses

The current study aimed to assess whether individual differences in fluid intelligence, as measured by abstract reasoning, emotional intelligence, and the Big Five personality traits would predict susceptibility to the continued influence effect. A total of 29 undergraduate students at Brescia University College read a news story that contained both misinformation and a retraction and were then tested on that news story. Participants also completed three additional questionnaires measuring personality traits, emotional intelligence, and abstract reasoning. It was predicted that individuals with lower levels of fluid and emotional intelligence, as well as those who scored higher in neuroticism and extraversion …

Examining The Development Of Hippocampal-Dependent Cognition In Young Children: Neuroimaging And Behavioral Approaches, Vanessa Vieites

FIU Electronic Theses and Dissertations

The current dissertation examined neurological and behavioral approaches to studying the development of large-scale spatial cognition and its underlying neurobiology in young children. Study one reviewed the literature on the development of the neurobiology of spatial navigation and reorientation, including the hippocampus and the parahippocampal, parietal, and prefrontal cortices, and discussed how researchers can overcome the challenges of studying these brain-behavior relations in young children. One solution, I propose, is to employ a hippocampal-dependent form of associative learning known as Pavlovian Trace Eyeblink Conditioning (EBC) to assess hippocampal functioning indirectly and safely in pediatric populations. For the following two empirical …

Normative Analysis Of Individual Brain Differences Based On A Population Mri-Based Atlas Of Cynomolgus Macaques, Qiming Lv, Mingchao Yan, Xiangyu Shen, Jing Wu, Wenwen Yu, Shengyao Yan, Feng Yang, Kristina Zeljic, Yuequan Shi, Zuofu Zhou, Longbao Lv, Xintian Hu, Ravi Menon, Zheng Wang

Brain and Mind Institute Researchers' Publications

The developmental trajectory of the primate brain varies substantially with aging across subjects. However, this ubiquitous variability between individuals in brain structure is difficult to quantify and has thus essentially been ignored. Based on a large-scale structural magnetic resonance imaging dataset acquired from 162 cynomolgus macaques, we create a species-specific 3D template atlas of the macaque brain, and deploy normative modeling to characterize individual variations of cortical thickness (CT) and regional gray matter volume (GMV). We observed an overall decrease in total GMV and mean CT, and an increase in white matter volume from juvenile to early adult. Specifically, CT …
