Love Is Blind: The Ironic Effect Of Fans’ Experience On Taste Perception, Jennifer L. Stoner, Maria A. Rodas

Marketing Faculty Publications

Many consumers may proclaim a love for a certain sensory experience (e.g., the taste of chocolate for “chocoholics”). These fans may have a wealth of experience consuming the product they love. In three studies, we find that these fans’ love actually blinds them in their ability to report nuances about the products they consume because of the use of top-down information processing. However, when presented with novel brand information, fans switch to a more bottom-up approach which allows greater discernment of the consumption experience. Prompting mindful consumption can also impact a fan’s ability to report a product’s nuances more accurately.

Chronic Exertional Compartment Syndrome: Surgical Treatment Vs Conservative Care, Molly Ruebke

Physician Assistant Scholarly Project Papers

Chronic exertional compartment syndrome (CECS) is a relatively rare pathology characterized by pain, tightness, and/or numbness in the affected calf upon performance of repetitive physical activity, most commonly with running or serving in the military. CECS usually has a delay in diagnosis due to low levels of awareness among clinicians and a wide range of differential diagnoses for chronic exertional leg pain. The natural course of CECS is often not self-limiting and therefore requires intervention, as symptoms can be severely debilitating and eventually force patients to avoid any provoking activity. The purpose of this literature review is to take a …
