Campus Recreation Student Employee Professional Development Curriculum: Perceived Student Employee Outcomes, Amanda Alpert Jessee

Electronic Theses and Dissertations

Kuh and colleagues (2008) use the term high-impact practices (HIPs) to describe co-curricular programs that are particularly effective in advancing student learning. The original list of HIPs does not include campus employment, which McClellan et al. (2018) argued should be added. According to the results from the 2019 NASPA survey reported by Burnside et al., recreational services is one of the top three areas in the number of student staff members. These student employees tend to come from a diverse academic background (Kampf & Teske, 2013) and may not be pursuing a future career within the recreation field. Campus recreation …

Single Versus Dual Response Demands In An Event-Based Prospective Memory Task With Context, Anne Elizabeth Vogel

Electronic Theses and Dissertations

Prospective memory (PM) refers to memory for future-based intentions. Previous research has explored how contextual information can support PM performance by lowering the cost to the ongoing task. For example, a study by Smith et al. (2017) demonstrated that knowing the contextual information of proximity to PM targets can affect attentional resource allocation. This was seen empirically as faster reaction times (RTs) when participants knew they were far from the target location, but longer RTs as participants knew they were approaching a target location. However, Vogel and Smith (in prep) found discrepancies in this pattern. This current study investigated these …

Examining The Relationship Between Toddlers’ Sleep Patterns, Negative Parenting, And Executive Function, Morgan Elizabeth Harris

Electronic Theses and Dissertations

Negative parenting can often be described as having three domains (i.e., laxness, verbosity, and over-reactivity, Arnold et al., 1993; Rhoades & O’Leary, 2007), which may have relations to toddlers’ behaviors, like executive function (EF) and sleep. However, this field is understudied, especially in early childhood development. One possible explanation for the lack of research in this field is that it can be difficult to study executive function in toddlers due to variability in the stability of regulatory behaviors and emerging regulatory abilities at this age range. Although positive sleep patterns (e.g., quality and quantity) have been linked to executive function, …
