Mindfulness-Based Stress Reduction is a secular behavioral medicine program that has roots in meditative spiritual practices. Thus, spirituality may partly explain Mindfulness-Based Stress Reduction outcomes. Participants (N = 279; M (SD) age = 45(12); 75% women) completed an online survey before and after an 8-week Mindfulness-Based Stress Reduction program. Structural equation modeling was used to test the hypothesis that, following Mindfulness-Based Stress Reduction, the relationship between enhanced mindfulness and improved health-related quality of life is mediated by increased daily spiritual experiences. Changes in both spirituality and mindfulness were significantly related to improvement in mental health. Although the initial mediation hypothesis …

Specific Contributions Of Ventromedial, Anterior Cingulate, And Lateral Prefrontal Cortex For Attentional Selection And Stimulus Valuation., Daniel Kaping, Martin Vinck, R Matthew Hutchison, Stefan Everling, Thilo Womelsdorf

Attentional control ensures that neuronal processes prioritize the most relevant stimulus in a given environment. Controlling which stimulus is attended thus originates from neurons encoding the relevance of stimuli, i.e. their expected value, in hand with neurons encoding contextual information about stimulus locations, features, and rules that guide the conditional allocation of attention. Here, we examined how these distinct processes are encoded and integrated in macaque prefrontal cortex (PFC) by mapping their functional topographies at the time of attentional stimulus selection. We find confined clusters of neurons in ventromedial PFC (vmPFC) that predominantly convey stimulus valuation information during attention shifts. …


Paradoxical Reversal Learning Enhancement By Stress Or Prefrontal Cortical Damage: Rescue With Bdnf., Carolyn Graybeal, Michael Feyder, Emily Schulman, Lisa M Saksida, Timothy J Bussey, Jonathan L Brigman, Andrew Holmes Nov 2011

Paradoxical Reversal Learning Enhancement By Stress Or Prefrontal Cortical Damage: Rescue With Bdnf., Carolyn Graybeal, Michael Feyder, Emily Schulman, Lisa M Saksida, Timothy J Bussey, Jonathan L Brigman, Andrew Holmes

Stress affects various forms of cognition. We found that moderate stress enhanced late reversal learning in a mouse touchscreen-based choice task. Ventromedial prefrontal cortex (vmPFC) lesions mimicked the effect of stress, whereas orbitofrontal and dorsolateral striatal lesions impaired reversal. Stress facilitation of reversal was prevented by BDNF infusion into the vmPFC. These findings suggest a mechanism by which stress-induced vmPFC dysfunction disinhibits learning by alternate (for example, striatal) systems.

The exploits of Martina Navratilova and Roger Federer represent the pinnacle of motor learning. However, when considering the range and complexity of the processes that are involved in motor learning, even the mere mortals among us exhibit abilities that are impressive. We exercise these abilities when taking up new activities - whether it is snowboarding or ballroom dancing - but also engage in substantial motor learning on a daily basis as we adapt to changes in our environment, manipulate new objects and refine existing skills. Here we review recent research in human motor learning with an emphasis on the computational …


“It Can Start From Anything”: An Existential Phenomenological Investigation Of Athletes’ Experiences Of Psychological Momentum, Greg Young May 2011

“It Can Start From Anything”: An Existential Phenomenological Investigation Of Athletes’ Experiences Of Psychological Momentum, Greg Young

Doctoral Dissertations

Psychological Momentum (PM) is a commonly recognized phenomenon in sport, yet remains one of the least understood (Taylor & Demick, 1994). Previous research examined PM using archival data (Gayton & Very, 1993; Gilovich, Vallone, & Tversky, 1985; Koehler & Conley, 2003; Silva, Hardy, & Crace, 1988), hypothetical and contrived scenarios (Eisler & Spink, 1998; Miller & Weinberg, 1991; Perreault, Vallerand, Montgomery, & Provencher, 1998; Vallerand, Colavecchio, & Pelletier, 1988), and actual performance (Mack, et al., 2008). More recently, Jones and Harwood (2008) used semi-structured interviews to examine participants’ …


Value Co-Creation With Customers Through Design Toolkits: The Importance Of Preference Fit And Psychological Ownership, Tingru Cui, Hua Ye, Hock Hai Teo Jan 2011

Value Co-Creation With Customers Through Design Toolkits: The Importance Of Preference Fit And Psychological Ownership, Tingru Cui, Hua Ye, Hock Hai Teo

Faculty of Engineering and Information Sciences - Papers: Part A

The information technologies increasingly enable companies to set up websites for customers to design and purchase their own individualized products. Although customer co-design offer benefits for both suppliers and customers, how to manage the co-design process, especially the central interface features of design toolkit have emerged as a contentious issue among researchers and practitioners. This paper focuses on the effects of both utilitarian and psychological customer-design product value (i.e., perceived preference fit and psychological ownership) on customers' purchase decision. Based on the self-determination theory, we propose that the effectiveness of the value increment mechanisms is influenced by three leading toolkit …
