Rigid and Non-rigid Facial Motions in Holistic and Featural Emotion Perception
Listed in ScienceDB
Naturalistic emotional encounters involve dynamic facial signals, comprising rigid (e.g., head turning) and non-rigid (e.g., muscle contractions forming facial expressions) movements.
Description
However, the neural mechanisms underlying the integration of featural (eyes, mouth) and holistic (whole face) cues during dynamic emotional signaling remain unclear. The current study employed a 2 (emotion: happy vs. angry) × 2 (study face: moving vs. static) × 3 (test face: whole face vs. eyes vs. mouth) design in two experiments (conducted in 2023-2026), with Experiment 1 examining rigid motion (N= 45, 31 females; age range = 18 - 26 years, M = 20.16, SD = 1.77) and Experiment 2 non-rigid motion (N = 42, 34 females; age range = 18 - 26 years, M = 20.71, SD = 1.84).
Participants performed an emotion-matching task.This dataset contains behavioral and electrophysiological data from both experiments, organized into two files: (1) behavioral results and (2) EEG data.Electrophysiological recordings were obtained using a 64-channel Ag-AgCl electrode system (NeuroScan, Charlotte, NC, United States). Vertical electrooculography (VEOG) was recorded via two electrodes placed supraorbital and infraorbital to the left eye, while horizontal electrooculography (HEOG) used two electrodes positioned 1.5 cm lateral to the outer canthi of both eyes.

All electrode impedances were maintained below 5 kΩ. Data were acquired at a sampling rate of 500 Hz with a 0.05-100 Hz band-pass filter, using a physical reference electrode located between Cz and CPz according to the 10-20 system. For preprocessing, EEG data were analyzed using Letswave toolbox in MATLAB R2021a (The MathWorks, Natick, MA).
Epochs were extracted from -200 to 800 ms relative to test stimulus onset, with a 200 ms pre-stimulus baseline correction. Data were band-pass filtered (0.1-30 Hz) and re-referenced to the average of all electrodes (Reutter et al., 2017). Ocular artifacts were removed through independent component analysis (ICA), with components exceeding ±75 μV amplitude rejected.
Forty ICA components were evaluated per participant, with a mean of two components removed per subject. No trials were excluded based on behavioral performance due to high response accuracy.
