Can Mere Possession Of A Consumer Product Boast Your Self-Efficacy? : A Cultural Perspective, Yixuan Gao

Lingnan Theses (MPhil & PhD)

Beggan (1992) introduced the mere ownership effect, suggesting that people evaluate owned objects more positively. Beggan argued that ownership fosters a psychological bond between people and their possessions, driven by self-enhancement motives (e.g., “I am good, thus my object must be good”). Yeung et al. (2017, 2020) extended the mere ownership effect, showing that ownership influences self-evaluations (e.g., I own a book so I am knowledgeable). Previous studies on the “person-based” mere ownership effect have primarily focused on East Asian participants. This thesis aims to compare cross-cultural differences, if any, in the “person-based” mere ownership effect (Study 1), and systematically …

Background

Summer vacation is a time when youth gain excessive weight. A key driver of unhealthy weight gain is poor dietary quality. The absence of consistent structure (e.g., school), is hypothesized to be one of the reasons for lower diet quality during summer. This study examined differences in school and summer dietary quality among a diverse cohort of children across three years. We also examined the impact of attending structured programs on children’s diets.

Methods

Parents of 1,032 children (age 5–14 years, 48% girls) completed a time use diary each day for 14-days during school (April/May) and again in summer …

Parents Of Adolescents On Electronic Use And Attention Deficit Hyperactivity Disorder: Parental Perspectives, Sleep, Internalization, Jessica Wiepking

Walden Dissertations and Doctoral Studies

ADHD in adolescents is a common diagnosis, with exposure to daily electronic use. There is strong evidence for a relationship between electronic use and ADHD in adolescents. However, there is a gap on electronic use, internalized feelings, and sleep behaviors in ADHD adolescents and how sleep behaviors might impact that relationship. ADHD has its core symptoms that impact the individual daily. These symptoms need to be taken into consideration when looking at internalized feelings and sleep behavior patterns. The theoretical framework that aligns with this study is the Dopaminergic Dysregulation Theory (DDT). This theory is a module that suggests that …

Moral Judgment Toward Individuals In Consensually Non-Monogamous Relationships As A Function Of Moral Foundations And Disgust Sensitivity, Dylan Selterman, Jeff Bowen, Ria Datwani, Amy C. Moors

Psychology Faculty Articles and Research

In two experiments we demonstrate how participants perceive individuals in consensually non-monogamous relationships (e.g., polyamory) more negatively compared to those in monogamous relationships, as a function of moral foundation variables and trait-level disgust sensitivity. In Study 1, we experimentally presented participants with vignettes depicting characters in one of two relationship types (monogamous or non-monogamous), after which participants completed character judgments (ethics) and relationship impressions. Participants viewed the characters in a monogamous relationship as more ethical and having higher relationship quality, and these associations were fully mediated by perceptions of the characters as pure, loyal, caring, fair, and honest. Participants high …
