Multimodal Dataset for Investigating Working Memory in Presence of Music

Year: 2024
N: 20
Access: PhysioNet — free download, requires free account
Tier: 3

Overview

Combines hemodynamic (fNIRS) with peripheral physiological responses during n-back tasks with and without music. The music intervention modulates affect and arousal, enabling cross-modal affect detection and cognitive workload studies.

Signals

Modality Signals
Forehead fNIRS (hemodynamic response)
Wrist EDA, HR, PPG
Behavioral Response time, accuracy

Relevance

Useful for studying how sensory stimulation (music) interacts with cognitive load — relevant to understanding how environmental stimuli might modulate arousal in ASD populations. The fNIRS + peripheral physiology combination allows investigation of central vs. autonomic contributions to cognitive load.
