Creativity incorporates both domain-general and domain-specific ideas. While previous studies have explored the impact of emotional intelligence (EI) on creativity in both domains, a consensus has not been reached, and the mechanism is currently unclear. In the present study, we examined which aspect of creativity EI was most strongly associated with in a group of undergraduates. Moreover, we explored the moderated mediation effect between EI and domain-specific creativity. In Study 1, 532 undergraduates completed questionnaires measuring EI, convergent and divergent creative thinking, and creative achievement. The results revealed that the most reliable positive correlations were between EI and domain-specific creativity. In Study 2, 926 undergraduates completed measurements of EI, resilience, gratitude, and creative achievement. The results revealed that resilience mediates the relationship between EI and creative achievement. Furthermore, gratitude moderated the indirect effect of EI on creative achievement through resilience. The indirect effect of EI on creative achievement was stronger for high-gratitude individuals than for low-gratitude individuals. This orientation and other results are discussed. Overall, our findings add further nuance to the relationship between EI and creativity in different domains. This study serves as a basis for other contributions aligned with these concepts.

Brain-Computer Interface (BCI) is a direct communication pathway between the brain and the external environment without using peripheral nerves and muscles. This emerging topic is suffering from serious issues such as malicious tampering and privacy leakage. To address this issue, we propose a novel communication scheme for BCI Systems. In particular, this scheme first utilizes high-dimensional chaotic systems with hyperbolic sine nonlinearity as the random number generator, then decorrelation operation is used to remove the physical characteristics of the output sequences. Finally, each of the sequences is applied in differential chaos shift keying (DCSK). Since each output sequence corresponds to a unique electrode, the communication data of different electrodes will not interfere with each other. Compared with popular multi-user DSCK schemes using Walsh code sequences, this scheme does not require the channel data of all electrodes while decoding. Therefore, this scheme has higher efficiency. Experimental results on communication data indicate that the proposed scheme can provide a high level of security.
