Cognitive control of physical activity and sedentary behavior is receiving increased attention in the neuroscientific and behavioral medicine literature as a means of better understanding and improving the self-regulation of physical activity. Enhancing individuals' cognitive control capacities may provide a means to increase physical activity and reduce(More)
This study investigated the effects of a brief tailored intervention on self-efficacy beliefs and exercise energy expenditure in active and inactive overweight and obese women. Participants were randomly assigned to either control (N = 50) or intervention (N = 47) conditions, and their exercise self-efficacy was assessed three times over a 12-week period.(More)
Exergames are becoming increasingly popular as a way of motivating people to exercise. However, merely adding exercise elements to a game may not achieve the desired level of motivation and long term adherence. By designing an exergame which takes into account the user's personality profile, the user's level of motivation to play the game and thus exercise(More)
Reading is a complex process, drawing on a variety of brain functions in order to link symbols to words and concepts. The three major brain areas linked to reading and phonological analysis include the left temporoparietal region, the left occipitotemporal region and the inferior frontal gyrus. Decreased activation of the left posterior language system in(More)
Exercise video games show promise as a tool for increasing physical activity by providing intrinsic motivation to play the game. Immersion is an aspect of gaming which can lead to increased motivation and enjoyment. Due to the recent rise of consumer level Head Mounted Displays (HMDs), high levels of immersion are possible. In this paper, we evaluate(More)
Guided by social cognitive theory (SCT), we investigated whether exercise self-regulatory efficacy beliefs can be activated nonconsciously in individuals experienced and inexperienced in exercise self-regulation, and whether these beliefs are automatically associated with exercise self-regulation processes. The study used a 2 (Exercise Self-Regulation(More)
Choosing the appropriate response given the circumstance is integral to all aspects of human behavior. One way of elucidating the mechanisms of choice is to relate behavior to neural correlates. Electrophysiological evidence implicates the ERP feedback-negativity (FN) and the P300 as promising neural correlates of reward processing, an integral component of(More)
