Based on Bandura’s Social Cognitive Theory, we tested how efficacy beliefs (self-efficacy and perceived collective efficacy) reciprocally influence activity engagement (work and task vigor, dedication and absorption) both directly and indirectly, through their impact on positive affect (enthusiasm, satisfaction, and comfort) over time. We conducted two longitudinal studies using independent sam...

People are good for your brain. Decades of research have shown that individuals who have a larger number of people in their social network or higher quality ties with individuals within their network have lower rates of morbidity and mortality across a wide range of health outcomes. Among these outcomes, cognitive function, especially in the context of brain aging, has been one area of particul...

Commonly, military training games and simulations depend on participants engaging in the immersive environment and then stopping to glean the meaning of their behaviors through (admittedly, increasingly sophisticated) After Action Reports. In order to derive the meaning of their experience, they must break cognitive engagement with their experience. This is, of course, sub-optimal. While it is ...

Drawing on the self-system model, this study conceptualized school engagement as a multidimensional construct, including behavioral, emotional, and cognitive engagement, and examined whether changes in the three types of school engagement related to changes in problem behaviors from 7th through 11th grades (approximately ages 12-17). In addition, a transactional model of reciprocal relations be...

Engagement in activities is crucial to improve quality of life in dementia. Yet, its measurement relies exclusively on behavior observation and the influence that behavioral and psychological symptoms of dementia (BPSD) have on it is overlooked. This study investigated whether quantity of movement, gauged with a wrist-worn accelerometer, could be a sound measure of engagement and whether apathy...
