Self-paced versions of many paradigms could have utility in probing cognitive systems. To validate several self-paced n-back paradigms, fourteen subjects performed four variations of the working memory task using visually presented letters as stimuli. Several areas in the frontal lobe, the anterior cingulate and a parietal network were consistently activated in the four variations: identity of ...

OBJECTIVE The goal of this research was to study whether a fast-paced television show immediately influences preschool-aged children's executive function (eg, self-regulation, working memory). METHODS Sixty 4-year-olds were randomly assigned to watch a fast-paced television cartoon or an educational cartoon or draw for 9 minutes. They were then given 4 tasks tapping executive function, includ...

OBJECTIVES The goal of this analysis was to determine the appropriate biventricular pacing target in patients with heart failure (HF). BACKGROUND Cardiac resynchronization therapy (CRT) decreases the risk of death and HF hospitalization. However, the appropriate amount of biventricular pacing is ill-defined. METHODS Mortality and HF hospitalization data from patients undergoing CRT in 2 tri...

conclusions de-stress training program significantly decreased the stress of mothers with show paced children, and the training effect was persistent. results data presented a significant difference between the control and experiment groups. also, results did not show a significant difference between the post-test and follow up. it means that the effect of training was persistent. background ha...

In order to investigate the influence of learner-controlled pacing in educational animation on instructional efficiency, three versions of an audio-visual computer animation and a narration-only presentation were used to teach primary school students the determinants of day and night. The animations were either system-paced using a continuous animation, learner-paced using discrete segments or ...

This paper presents a novel e-learning instructional model and its application to teaching a Java language programming course for information technology specialists working for the Spanish public administration. This is a general-purpose instructional model, based on the concept of learning objective and composed of learning objects. Additionally, a blended approach to the learning process in w...

OBJECTIVES The purpose of this study was to evaluate the rate of recognition of atrial fibrillation (AF), use of warfarin and prevalence of cerebrovascular accident (CVA) in paced versus unpaced patients during admission to a tertiary care teaching hospital. BACKGROUND The presence of AF underlying a continuously paced rhythm may be under recognized and result in a lower rate of anticoagulati...
