Does Physical Activity Influence Semantic Memory Activation In Amnestic Mild Cognitive Impairment?, J. Smith, Kristy Nielson, John Woodard, Michael Seidenberg, Matthew Verber, Sally Durgerian, Piero Antuono, Alissa Butts, Nathan Hantke, Melissa Lancaster, Stephen Rao Jul 2014

Does Physical Activity Influence Semantic Memory Activation In Amnestic Mild Cognitive Impairment?, J. Smith, Kristy Nielson, John Woodard, Michael Seidenberg, Matthew Verber, Sally Durgerian, Piero Antuono, Alissa Butts, Nathan Hantke, Melissa Lancaster, Stephen Rao

Kristy Nielson

The effect of physical activity (PA) on functional brain activation for semantic memory in amnestic mild cognitive impairment (aMCI) was examined using event-related functional magnetic resonance imaging during fame discrimination. Significantly greater semantic memory activation occurred in the left caudate of High- versus Low-PA patients, (P=0.03), suggesting PA may enhance memory-related caudate activation in aMCI.


Physical Activity And Brain Function In Older Adults At Increased Risk For Alzheimer’S Disease, J. Carson Smith, Kristy A. Nielson, John L. Woodard, Michael Seidenberg, Stephen M. Rao Jul 2014

Physical Activity And Brain Function In Older Adults At Increased Risk For Alzheimer’S Disease, J. Carson Smith, Kristy A. Nielson, John L. Woodard, Michael Seidenberg, Stephen M. Rao

Kristy Nielson

Leisure-time physical activity (PA) and exercise training are known to help maintain cognitive function in healthy older adults. However, relatively little is known about the effects of PA on cognitive function or brain function in those at increased risk for Alzheimer’s disease through the presence of the apolipoproteinE epsilon4 (APOE-ε4) allele, diagnosis of mild cognitive impairment (MCI), or the presence of metabolic disease. Here, we examine the question of whether PA and exercise interventions may differentially impact cognitive trajectory, clinical outcomes, and brain structure and function among individuals at the greatest risk for AD. The literature suggests that the protective …


Cognitive Bias Modification: Past Perspectives, Current Findings, And Future Applications, Paula T. Hertel, Andrew Mathews Mar 2014

Cognitive Bias Modification: Past Perspectives, Current Findings, And Future Applications, Paula T. Hertel, Andrew Mathews

Paula T Hertel

Research conducted within the general paradigm of Cognitive Bias Modification (CBM) reveals that emotional biases in attention, interpretation, and memory are not merely associated with emotional disorders but contribute to them. After briefly describing research on both emotional biases and their modification, we examine similarities between CBM paradigms and older experimental paradigms used in research on learning and memory. We also compare the techniques and goals of CBM research to other approaches to understanding cognition/emotion interactions. From a functional perspective, the CBM tradition reminds us to use experimental tools to evaluate assumptions about clinical phenomena and more generally, about causal …


Maritime Traffic Management: A Need For Central Coordination?, Fulko Van Westrenen, Gesa Praetorius Jan 2014

Maritime Traffic Management: A Need For Central Coordination?, Fulko Van Westrenen, Gesa Praetorius

Gesa Praetorius

Traffic management is not formally organised in the maritime domain. Ships are autonomous and find their own way. Traffic is organised through rules, regulations, and “good seamanship”; it is a distributed system. In areas of high traffic-density support is proved by vessel traffic service (VTS) to promote traffic safety and fluency. VTS does not take control. This organisational structure has proven itself in situations with sufficient resources. When resources become insufficient (e.g. not enough sailing space), the traffic needs an organising mechanism. In this article, the authors argue that the most promising way to do this is by organising centralised …


Hemispheric Processes In The Perception Of Art, A Literature Review, Megan Levy Jan 2014

Hemispheric Processes In The Perception Of Art, A Literature Review, Megan Levy

Megan Levy

A literature review on Jeffrey Coney’s and Christine Bruce’s “Hemispheric Processes in the Perception of Art” (Journal of the International Association of Empirical Aesthetics, Empirical Studies of the Arts, Vol. 22(2) 181-200, 2004) presenting the results of their exploratory study on lateral asymmetry in the aesthetic evaluation of European art. This literature review proposes that Lateralization Theory, and specifically hemispheric preferences in art, are vast fields full of mystery and surprises, which require continuous research work within a deep understanding of the historical context. Coney’s and Bruce’s study is an example of interesting hard work which invites curiosity and replication, …
