Abstract
The Subliminal Affective Priming Effect (SAPE) can be accomplished on the arousal level, which manifests that the effect appears when the subjects judge the arousal values of the target stimulus. Based on Electroencephalogram (EEG) signals, this paper analyzes whether the SAPE appears on the arousal level. For effectively solving the problems of the modal aliasing and reconstruction error for EEG study, we introduce the Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN) algorithm. And Multi-scale Permutation Entropy (MPE) is a common method for the time series. According to the nonlinear characteristics of EEG signals, this paper combines CEEMDAN with MPE to the judgement of SAPE. Firstly, this paper introduces the principle and computational procedure of the analysis method of SAPE. Then, we perform a one-way repeated-measures ANOVAs (ORANOVAs) for the arousal values. At last, the experimental results are analyzed. The experimental results show that the SAPE occurs in the negative priming group, but SAPE is not observed in the positive priming group, which demonstrates that the analysis method can be used to judge whether the SAPE exists on the arousal level. We also further verify this conclusion by performing the ORANOVAs.
