EC-CEI02 25A: Neurophysiological and Physiological Dataset from MBA Business Pitch Presentations

This dataset was collected as part of an applied educational research study focused on analyzing neurophysiological and physiological responses during entrepreneurial pitch presentations delivered by graduate-level students. The data collection was conducted within the context of business education at EGADE Business School, involving students enrolled in an MBA program presenting their business ideas. The data were collected on July 2, 2025, during a single experimental session structured into two consecutive presentation turns. The session design allowed for the observation of multiple teams under comparable contextual conditions while managing logistical and temporal constraints. Session Structure: Single session with two presentation turns - Turn 1: Four student teams participated. - Turn 2: Three student teams participated. 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. 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.
