The Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting, Geoffrey Reliquias
The Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting, Geoffrey Reliquias
Honors Theses
Previous research has indicated that aspects of cognitive inhibition may be enhanced after engaging in acute exercise. Notably, cognitive inhibition has been theorized as a potential mechanism for a form of active forgetting known as retrieval-induced forgetting (RIF). Given that cognitive inhibition may explain the RIF phenomenon, and is also influenced by exercise, it is plausible that acute exercise may directly influence RIF. To our knowledge, only one study has examined whether acute exercise has an effect on RIF. The findings of that study did not find a statistically significant effect for RIF; however, we believe that the rather small …
Effects Of Mindfulness Meditation On Selective, Sustained Attention, Brain Neural Oscillations, And Short-Term Memory, Anamaria Guzman
Effects Of Mindfulness Meditation On Selective, Sustained Attention, Brain Neural Oscillations, And Short-Term Memory, Anamaria Guzman
Honors Theses
The following extended literature review and research proposal study started initially as a complete research proposal but, due to the challenges COVID-19 has brought, it has become a stand-alone piece of work without data collection. The goal is to synthesize a broad range of literature and previous research on mindfulness meditation and its effects on attention, memory, and brain activity and thus, offering a new perspective and a proposed research path on this subject. This proposed research study, besides previous studies, indicates that mindfulness meditation is expected to improve and enhance selective and sustained attention, which results in better attentional …
The Effects Of Insulin-Like Growth Factor-1 (Igf-1) And Insulin-Like Growth Factor Receptor (Igfr) Regulation On Cognition And Structure Of Astrocytes, Sariya Khan
Honors Theses
Insulin-like growth factor-1 (IGF-1) is a neuroendocrine signaling hormone that plays an integral role in bone and tissue growth and development. Inhibition of this hormone is known to disrupt the chemistry of the brain, resulting in cognitive impairments such as those seen in many common neurodegenerative diseases. While much research has been conducted on neurons and their relation with IGF-1, the role of astrocytes still needs to be explored. Our research investigates how astrocytes are affected as a result of IGF-1 regulation. Preliminary studies in our laboratory established a connection between IGF-1 and glial fibrillary acidic protein (GFAP), and in …
Biomarkers And Neuropsychological Change: A Pilot Study Of Three Months Of The Interactive Physical And Cognitive Exercise System (Ipaces™) For Older Adults, Jessica Stark
Honors Theses
The current pilot study of the interactive Physical and Cognitive Exercise System (iPACES™) examined the relationship between biomarkers and cognitive change over three months of neuroexergaming, wherein older adults pedaled and steered along a virtual bike path to complete a list of errands (Memory Lane™). Executive function and saliva were measured at baseline, mid (6-week), and three months. Results revealed moderate to large correlations between executive function and salivary biomarkers cortisol, BDNF, and IGF1. These findings suggest that neuroexergaming interventions such as iPACES™ may impact both cognitive and neurobiological pathways and perhaps could be an effective way to promote healthy …
Mindful Meditation And Physical Exercise: Neuropsychological Effects, Emma Stein
Mindful Meditation And Physical Exercise: Neuropsychological Effects, Emma Stein
Honors Theses
An abundance of prior research has indicated the robust relationship between physical exercise and cognition (Colcombe & Kramer, 2003). More recent research has investigated the cognitive and stress-relieving benefits of mind-body exercise, involving a combination of mindful meditation techniques with physical movements (Wayne, et al., 2014). Among these two cognitively enhancing techniques, is “exergaming,” which provides interactive physical exercise with a virtual environment. Research on exergaming has found additional cognitive benefits of interactive mental and physical exercise compared to regular physical exercise (Anderson-Hanley, et al., 2012). However, it remains unclear as to which type of mental engagement is required during …
Cognitive Effects Of Combined Physical And Mental Exercise: Interactive Vs. Synchronous, Caitlin Moore
Cognitive Effects Of Combined Physical And Mental Exercise: Interactive Vs. Synchronous, Caitlin Moore
Honors Theses
Many high quality randomized clinical trials have now clarified the strong relationship between exercise and cognition (Colcombe & Kramer, 2003). A growing area of exercise research has been focused on the effects of “exergaming” on cognitive function. Exergaming provides an individual with the ability to physically interact with a virtual environment (O’Leary et al., 2011). Recent research has shown an added cognitive benefit of interactive mental and physical exercise, when using a virtual reality-enhanced stationary bike. It is unclear whether interactivity is required, or if added cognitive benefit is "simply" from doing two things at the same time and reaping …
Electrophysiological Indices Of Aesthetically Stimulated Processes In Art-Experienced Individuals As Compared To Art-Naïve Individuals, Katharine E. Hartnack
Electrophysiological Indices Of Aesthetically Stimulated Processes In Art-Experienced Individuals As Compared To Art-Naïve Individuals, Katharine E. Hartnack
Honors Theses
Aesthetic judgment processes were investigated in art-experienced and art-naïve individuals. Previous electrophysiological data suggest that aesthetic judgment is a two-stage process (Hofel & Jacobson, 2007). The first stage of aesthetic judgment is impression formation which is not spontaneous, and is reflected by an early Event Related Potential (ERP) frontocentral deflection. The second stage reflected by a lateralized late ERP positivity, evaluative categorization is also not spontaneous. Participants in the current study were instructed to either simply view black and white geometric patterns or were instructed to contemplate the beauty of the patterns. Results suggest that aesthetically stimulated processes differ between …
Neuropsychological And Neurophysiological Effects Of Low-Intensity Strengthening Exercise On Cognition, Vadim V. Yerokhin
Neuropsychological And Neurophysiological Effects Of Low-Intensity Strengthening Exercise On Cognition, Vadim V. Yerokhin
Honors Theses
With the growing aging population, it’s becoming increasingly important to find ways to either deter or prevent dementia. To date, most research has concentrated on the effects of aerobic exercise on cognition. Unfortunately, a large portion of older adults are often contraindicated to perform aerobic exercise due to different risk factors, which increase with age. Alas, alternate ways of exercise are necessary. Low-intensity strengthening exercise is a type of exercise aimed at improving balance and strengthening muscles without requiring one to overstrain. The current 11-week long exercise study test neuropsychological effects of exercise with a neuropsychological battery and neurophysiological effects …
