title: EC-CEI01 25A: Neurological and Physiological Data from Simulated and Authentic Presentation Scenarios in Innovation and Entrepreneurship Education

description: This dataset was collected as part of a quasi-experimental study designed to compare neurophysiological responses in two instructional conditions: (a) a simulated practice environment where students rehearsed and received instructor feedback, and (b) a real presentation environment involving an external industry partner (socio formador). The study was developed within the context of Educational Innovation Management at the School of Humanities and Business, incorporating entrepreneurial learning elements and authentic evaluation scenarios. Two data collection sessions were conducted: Pre-phase (2025-06-03): Simulated Scenario Students participated in a simulated practice session in which they refined their pitch, rehearsed their presentation structure, and received formative feedback from their instructor. During this session, the environment was controlled, low-stakes, and focused on preparation, iterative improvement, and guided practice. Post-phase (2025-06-10): Real Presentation Scenario Students presented their opportunity proposal to an external industry partner (socio formador). This session represented a high-stakes, authentic evaluation environment in which students were expected to demonstrate professional communication, clarity of value proposition, and persuasive argumentation. Both sessions replicated the same presentation tasks; however, the emotional, cognitive, and contextual demands differed significantly due to the presence of a real external evaluator in the post-phase. Biometric Devices Used Muse 2 EEG Headband : Neurophysiological activity was recorded using the Muse 2 EEG headband, which captures brain electrical signals at high temporal resolution. ● Sampling rate: 256 Hz ●Electrode channels: TP9, AF7, AF8, TP10 ● Frequencies captured: delta, theta, alpha, beta, and gamma bands. These signals allow the characterization of cognitive states such as attention, alertness, mental fatigue, and cognitive workload throughout both the simulated and real presentation phases. Embrace Plus Wristband (Empatica): Physiological activity was recorded using the Embrace Plus, a multimodal wearable device designed for continuous monitoring of autonomic nervous system responses. The device captures several biomarkers relevant to cognitive and emotional states. Biomarkers collected: ●Electrodermal Activity (EDA): Records phasic and tonic skin conductance responses associated with arousal, stress, engagement, and emotional activation. Sampling frequency: approximately 4 Hz. ●Blood Volume Pulse (BVP): Measures peripheral blood flow through photoplethysmography (PPG), supporting the calculation of: ●Heart Rate (HR), Heart Rate Variability (HRV), Indicators associated with stress regulation, workload, and autonomic balance. ●Skin Temperature: Captures peripheral thermoregulation changes related to stress, cognitive effort, and affective responses.Sampling frequency: ~1 Hz. These multimodal signals support the examination of students affective and physiological responses during both practice and real evaluation conditions, enabling analyses of stress, engagement, attentional changes, and autonomic activation.
