Lying is known to evoke stress and cognitive load. Both form cues to deception and lead to an increase in sympathetic nervous system (SNS) activity. But in reality, deceivers stick to the truth most the time and only lie occasionally. The present study therefore examined in an interactive suspect interview setting, whether deceivers still have clearly diverging cognitive and emotional processes from truth tellers when only having the intention to lie incidentally. We found that deceivers who lied constantly diverge from truth tellers in SNS activity, self-reported cognitive load and stress. Across all interviews, SNS activity correlated stronger with self-reports of cognitive load than stress, which supports the cognitive load approach. Furthermore, deceivers who told the truth and lied on only one crucial question, particularly diverged in self-reported stress from truth-tellers. In terms of SNS activity and self-reported cognitive load, no differences were found. Theoretical and practical implications are discussed.

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.

Limiting cognitive resources negatively impacts motor learning, but its cognitive mechanism is still unclear. Previous studies failed to differentiate its effect on explicit (or cognitive) and implicit (or procedural) aspects of motor learning. Here, we designed a dual-task paradigm requiring participants to simultaneously perform a visual working memory task and a visuomotor rotation adaptation task to investigate how cognitive load differentially impacted explicit and implicit motor learning.

Although ultrasound (US) appears to complement traditional anatomy teaching, limited objective data exist on its efficacy. Existing literature often relies on student perceptions rather than performance-based outcomes. Additionally, the role of spatial understanding (SU)-the ability to mentally manipulate and interpret 3D anatomical relationships-and cognitive load (CL)-the mental effort required to learn-remains underexplored in the context of US-based instruction.

This study aimed to evaluate the association between a dietary education approach grounded in the transtheoretical model and cognitive load theory and glycemic control and pregnancy-related outcomes in patients diagnosed with gestational diabetes mellitus (GDM). A retrospective analysis was performed using clinical data from 126 pregnant women with GDM who received care at our hospital between September 2021 and September 2023. Participants were grouped based on the type of nursing intervention received: a control group that underwent standard care and an observation group that received an additional cognitive load-informed dietary education program based on transtheoretical model.
