The role of pedagogical agents in multimedia learning as an element that gives students social cues to promote cognition has been demonstrated in terms of enhancing students' academic performance and intrinsic motivation. Cognitive load is an important factor in measuring the effectiveness of multimedia learning, but the results of pedagogical agents' effects on learners' cognitive load have been consistently inconsistent. In this study, a meta-analytical approach was used to comprehensively analyse 24 empirical studies to investigate the effects of pedagogical agents on students' cognitive load in multimedia learning and the moderating factors in their process. The results showed that the teaching agent only slightly reduced the cognitive load. Moderating analyses show that the pedagogical agent appearance, pedagogical agent role, subject domain, form of media mix, intervention duration, and learning pace play a moderating role in the process of the pedagogical agent's influence on cognitive load, and can significantly reduce the cognitive load of learners.

Introduction: Exoskeletons have the potential to reduce workplace injuries; however, their use could increase cognitive load. While prior studies have explored the cognitive load impacts of passive and active back-support exoskeletons, research comparing their effects in construction-related tasks remains limited, particularly using electroencephalogram theta brainwave activity as a cognitive load indicator. This study assesses and compares the cognitive load implications of active and passive back-support exoskeletons relative to a baseline (i.

Human vision deals with two major limitations. First, vision is strongly foveated and deteriorates with eccentricity. Second, visual attention selectively prioritizes some stimuli over others.

Objective: To clarify the potential risks and causative mechanisms of glare from nighttime road fill lights on driving safety, this study investigates the dual interference of glare-induced visual cognitive load and physiological stress.
Methods: A field driving experiment involving 20 drivers was conducted, with real-time collection of visual data (e.g.

Background: Alzheimer's disease (AD) patients and animal models exhibit an altered gut microbiome that is associated with pathological changes in the brain. Intestinal miRNA enters bacteria and regulates bacterial metabolism and proliferation. This study aimed to investigate whether the manipulation of miRNA could alter the gut microbiome and AD pathologies.

Background: Clinical communication is central to the delivery of effective, timely, and safe patient care. The use of text-based tools for clinician-to-clinician communication-commonly referred to as secure messaging-has increased exponentially over the past decade. The use of secure messaging has a potential impact on clinician work behaviors, workload, and cognitive burden.
