Role Of Feedback And Social Anxiety In Dating Situations, Kanika Singh

Masters Theses

Social anxiety has been linked to both the Fear of Negative Evaluation (FNE) and the Fear of Positive Evaluation, suggesting that receiving feedback (whether positive or negative) is difficult for persons with social anxiety. However, little research has examined whether receiving feedback in an evaluative setting (e.g., dating) can directly affect social anxiety levels. Thus, this study examined whether varying types of feedback (negative, positive, and neutral) can affect the levels of social anxiety for individuals in a dating scenario. Feedback was provided to participants and examined in relation to their levels of FNE and FPE. Participants consisted of undergraduate …

Pathway Lasso: Pathway Estimation And Selection With High-Dimensional Mediators, Yi Zhao, Xi Luo

Faculty, Staff and Student Publications

In many scientific studies, it becomes increasingly important to delineate the pathways through a large number of mediators, such as genetic and brain mediators. Structural equation modeling (SEM) is a popular technique to estimate the pathway effects, commonly expressed as the product of coefficients. However, it becomes unstable and computationally challenging to fit such models with high-dimensional mediators. This paper proposes a sparse mediation model using a regularized SEM approach, where sparsity means that a small number of mediators have a nonzero mediation effect between a treatment and an outcome. To address the model selection challenge, we innovate by introducing …
