EC-CEI03 25A:: Neurophysiological and Physiological Data in Negotiation Training (Neuro-negotiation)

This dataset was collected as part of a quasi-experimental study designed to analyze neurophysiological responses during a high-stakes negotiation exercise focused on persuasive communication, emotional regulation, and crisis-handling strategies. The activity, referred to as the NeuroNegotiation Challenge, exposed students to scenarios requiring real-time decision-making, persuasive framing, and adaptive management of objections or conflicts. Two data-collection phases were conducted to compare cognitive-emotional variations over time: -Pre-phase (2025-04-22) -Post-phase (2025-06-30) Biometric Devices Used Muse 2 EEG Headband: Neuroelectrical activity was recorded using the Muse 2 EEG headset, enabling fine-grained monitoring of cortical oscillations associated with executive functions relevant to persuasion and crisis management. Device specifications: ● Sampling rate: 256 Hz ●Electrode channels: TP9, AF7, AF8, TP10 ●Frequency bands captured: delta, theta, alpha, beta, gamma These signals support characterizations of attention, alertness regulation, inhibitory control, cognitive workload, and mental fatigue during the negotiation phases. Embrace Plus Wristband (Empatica): Physiological activity was recorded using the Embrace Plus multimodal wearable, which monitors biomarkers associated with autonomic nervous system activation in emotional and stress-laden situations. Biomarkers collected: ●Electrodermal Activity (EDA): Phasic and tonic conductance responses linked to arousal, emotional activation, stress, and heightened engagement (approx. 4 Hz sampling). ●Blood Volume Pulse (BVP): Peripheral pulse wave enabling the derivation of Heart Rate (HR) , Heart Rate Variability (HRV). Both reflect sympathetic–parasympathetic balance, cognitive effort, and adaptive stress regulation. ●Skin Temperature: Peripheral thermoregulation indicator sensitive to stress reactivity, cognitive workload, and affective shifts (~1 Hz sampling).
