Cognitive Load

The goal of this observational study is to measure the cognitive load (mental effort) of anesthesia nurses during real surgical procedures at Hospital Clínic de Barcelona, Spain. The main questions it aims to answer are: * Does cognitive load vary across the three phases of anesthetic care (induction, maintenance, and emergence/recovery)? * Is cognitive load higher during general anesthesia than during spinal anesthesia with sedation? * How do surgical specialty and patient complexity relate to cognitive load? * How does monitor alarm perception relate to cognitive load during surgery? Participants (anesthesia nurses) will complete the NASA Task Load Index (NASA-TLX) questionnaire - a validated 6-item tool measuring mental effort - three times per surgical case: after induction or spinal block, during maintenance, and after patient awakening or sedation reversal. They will also answer 4 brief questions about alarm management at the end of each case. No changes are made to clinical care. Participation adds approximately 11 minutes per surgical case.

This study aims to evaluate and compare the effects of using standardized patients versus static manikins in nursing education for arterial blood pressure monitoring and stabilization training. The primary objective is to investigate the impact of these two different simulation methods on students' cognitive load, clinical skills, and self-efficacy levels. Arterial pressure monitoring is a critical, invasive intervention commonly performed in intensive care units and operating rooms, requiring a high degree of precision. While traditional technical skill assessments usually focus solely on procedural success scores or completion speed, this study utilizes the framework of Cognitive Load Theory to examine the mental toll (intrinsic, extrinsic, and germane load) and psychological readiness (self-efficacy) experienced by nursing students during the procedure. The study will be conducted as a randomized controlled experimental trial with 3rd-year nursing students who have successfully completed their Medical-Surgical Nursing course. Participants will be randomly assigned to either the experimental group or the control group: The Experimental Group will receive theoretical and practical training, followed by performing the arterial pressure monitoring line stabilization on a "Standardized Patient" (an experienced healthcare professional acting a scenario with a moving limb to mimic real clinical chaos without any actual invasive intervention). The Control Group will receive the same training but will perform the stabilization procedure on a traditional static medical manikin. Data will be collected using a Descriptive Information and Performance Recording Form (to measure procedural time and error rates), the Cognitive Load Scale, and the Self-Efficacy Scale for Clinical Skills. Measurements will be taken at baseline (pre-test) and immediately after the intervention (post-test). The findings of this study are expected to provide evidence-based guidance for developing "mind-friendly" nursing curricula and safer, more realistic simulation protocols that enhance student self-efficacy while ensuring patient safety before entering actual clinical environments.

This study aims to determine how different levels of physical fatigue influence cognitive load and performance during dual-task activities. 1. To assess the changes in cognitive task performance under varying levels of physical fatigue. 2. There is an association between cognitive loading and physical fatigue.

* The aim is to determine the impact of cognitive load on balance recovery mechanisms following perturbations in young adults. * To evaluate how secondary task is influenced by cognitive load and vice versa. * To compare the impact of cognitive load on balance recovery mechanisms following perturbations in male and female young adults. * This study interrelates the cognitive load, postural stability, balance recovery in the result of perturbation and effects on participants.
