“…On the other hand, expressions of negative emotions can induce negative emotions in the partner (Friedman et al, 2004;Kulesza et al, 2015). An imbalance in non-verbal communication would be observed during subjectively positive rated conversation (Numata et al, 2021). In fact, emotional mimicry is not a merely automatic response of facial expressions in humans, and facial expressions are used as means to communicate social intentions.…”

Virtual agents (computer-graphics-based agents) have been developed for many purposes such as supporting the social life, mental care, education, and entertainment of both young and old people individuals. Promoting affective communication between young/old users and agents requires clarifying subjective feelings induced by an agent's expressions. However, an emotional response model of agents to induce positive feelings has not been fully understood due to differences in emotion perception between young and old adults. We investigated subjective feelings induced when facing with a non-human computer-graphics-based agent's emotional responses in consideration of differences of emotion perception between young adults and old adults. To emphasize the differences in emotion perception, the agent's expressions were developed by adopting exaggerated human expressions. The differences in their emotion perception of happy, sadness, and angry between young and old participants were then identified through a preliminary experiment. Considering the differences in emotion perception, induced feelings when facing with the agent's expressions were analyzed from the three types of emotion sources of the participant, agent, and other, which was defined as subject and responsibility of induced emotion. The subjective feelings were evaluated using a subjective rating task with 139 young and 211 old participants. The response of the agent that most induced positive feelings was happy when participants felt happy, and that was sad when participants felt sad, regardless emotion sources in both young and old groups. The response that most induced positive feelings was sad when participants felt angry and emotion sources were participant and the agent, and that was angry when the emotion source was other. The emotion types of the response to induce most positive feelings were the same between the young and old participants, and the way to induce most positive feelings was not always to mimic the emotional expressions, which is a typical tendency of human responses. These findings suggest that a common agent response model can be developed for young and old people by combining an emotional mimicry model with a response model to induce positive feelings in users and promote natural and affective communication, considering age characteristics of emotion perception.

Time-Frequency (T-F) analysis of EEG is a common technique to characterise spectral changes in neural activity. This study explores the limitations of utilizing conventional spectral techniques in examining cyclic event-related cortical activities due to challenges, including high inter-trial variability. Introducing the Cycle-Frequency (C-F) analysis, we aim to enhance the evaluation of cycle-locked respiratory events. For synthetic EEG that mimicked cycle-locked pre-motor activity, C-F had better frequency and time precision compared to conventional T-F analysis, even when the number of trials was reduced from 50 to 20. Preliminary validations using EEG data during both unloaded breathing and loaded breathing (that evokes pre-motor activity) suggest potential benefits of using the C-F method, particularly in normalizing time units to cyclic activity phases and refining baseline placement and duration. The proposed approach could provide new insights for the study of rhythmic neural activities, complementing T-F analysis.
