The Effects Of Caffeine And Expectancy On Short Term Memory, Sara O'Brien Oct 2011

The Effects Of Caffeine And Expectancy On Short Term Memory, Sara O'Brien

Doctoral Dissertations and Master's Theses

Although caffeine is the most widely used drug in the world, research on the effects of caffeine on mental performance tasks (especially short term memory tasks) is inconclusive. One possible explanation for this limited understanding is the lack of studies accounting for participant expectancy surrounding caffeine. This study examined the effects of caffeine dosage (0mg, 200mg, and 400mg) and expectancy related to past caffeine use (positive, negative) on short term memory span task. A two-way Analysis of Variance showed that the two independent variables (caffeine dose and expectancy), did not significantly influence the short term memory span score. However, the …


Neural Correlates Of The Implicit Association Test: Evidence For Semantic And Emotional Processing, Jason R. Themanson, John K. Williams Aug 2011

Neural Correlates Of The Implicit Association Test: Evidence For Semantic And Emotional Processing, Jason R. Themanson, John K. Williams

Jason R. Themanson, Ph.D

The implicit association test (IAT) has been widely used in social cognitive research over the past decade. Controversies have arisen over what cognitive processes are being tapped into using this task. While most models use behavioral (RT) results to support their claims, little research has examined neurocognitive correlates of these behavioral measures. The present study measured event-related brain potentials (ERPs) of participants while completing a gay-straight IAT in order to further understand the processes involved in a typical group bias IAT. Results indicated significantly smaller N400 amplitudes and significantly larger LPP amplitudes for compatible trials than for incompatible trials, suggesting …


The Effect Of Choice In Exercise Intensity On Affect And Cognition, Annegracien Delaunay Aug 2011

The Effect Of Choice In Exercise Intensity On Affect And Cognition, Annegracien Delaunay

Masters Theses & Specialist Projects

While there are studies linking positive psychological outcomes with exercise, few have focused on choice as a moderating factor. The research that has examined choice as a moderator yielded mixed results. Currently no research has looked at the impact of choice of exercise intensity on the psychological benefits of acute exercise; specifically, affective and cognitive gains. According to Landers (2008), acute exercise refers to a single bout of exercise usually lasting a short duration, whereas chronic exercise refers to long term repeated bouts of exercise (e.g., weeks, months, or years). Participants in this study consisted of 117 collegiate psychology students. …


The Behavioral Effects Of Increased Physical Activity On Preschoolers At Risk For Attention Deficit Hyperactivity Disorder, Jasmin L. Roberts Jan 2011

The Behavioral Effects Of Increased Physical Activity On Preschoolers At Risk For Attention Deficit Hyperactivity Disorder, Jasmin L. Roberts

Masters Theses 1911 - February 2014

Physical activity (PA) has many health benefits, both physical and psychological. PA has been linked to improved cognitive functioning, superior overall health, and enhanced emotional well-being in populations ranging from school-age children to older adults. There has been less research, however, examining the benefits of PA in atypical preschool populations.

The present study examined the efficacy of a PA intervention in preschool-aged children at risk for attention deficit hyperactivity disorder (ADHD). ADHD symptomatology, response inhibition, and physical activity were measured at three time points over a 6-month period. Results provide support for the efficacy of PA as an alleviative tool …

Beyond Tolerance: Consciously Using Universal Energy Laws, Discernment, And Harmonious Relationship Principles, Carroy U. Ferguson Dec 2010

Beyond Tolerance: Consciously Using Universal Energy Laws, Discernment, And Harmonious Relationship Principles, Carroy U. Ferguson

Carroy U "Cuf" Ferguson, Ph.D.

Every day we, as human beings, maneuver through a myriad of circumstances in our individual and collective life spaces. Central to our experiences is the nature, kind, and quality of our relationships. When we encounter differences (racial, ethnic, cultural, religious, economic, sexual orientation, the mentally and physically challenged), a common issue that often emerges in our experiences is the extent to which we use tolerance in relating to other people and circumstances. For this reason, I want to discuss the nature of tolerance and its limitations, and how to move beyond tolerance by consciously using Universal Energy Laws, discernment, and …
