Background Quantitative electroencephalography (EEG) analysis offers the opportunity to study high-level cognitive processes across psychiatric disorders. In particular, EEG microstates translate the temporal dynamics of neuronal networks throughout the brain. Their alteration may reflect transdiagnostic anomalies in neurophysiological functions that are impaired in mood, psychosis, and autism spectrum disorders, such as sensorimotor integration, speech, sleep, and sense of self. The main questions this study aims to answer are as follows: 1) Are EEG microstate anomalies associated with clinical and functional prognosis, both in resting conditions and during sleep, across psychiatric disorders? 2) Are EEG microstate anomalies associated with differences in sensorimotor integration, speech, sense of self, and sleep? 3) Can the dynamic of EEG microstates be modulated by a non-drug intervention such as light hypnosis? Methods This prospective cohort will include a population of adolescents and young adults, aged 15 to 30 years old, with ultra-high-risk of psychosis (UHR), first-episode psychosis (FEP), schizophrenia (SCZ), autism spectrum disorder (ASD), and major depressive disorder (MDD), as well as healthy controls (CTRL) (N = 21 × 6), who will be assessed at baseline and after one year of follow-up. Participants will undergo deep phenotyping based on psychopathology, neuropsychological assessments, 64-channel EEG recordings, and biological sampling at the two timepoints. At baseline, the EEG recording will also be coupled to a sensorimotor task and a recording of the characteristics of their speech (prosody and turn-taking), a one-night polysomnography, a self-reference effect task in virtual reality (only in UHR, FEP, and CTRL). An interventional ancillary study will involve only healthy controls, in order to assess whether light hypnosis can modify the EEG microstate architecture in a direction opposite to what is seen in disease. Discussion This transdiagnostic longitudinal case–control study will provide a multimodal neurophysiological assessment of clinical dimensions (sensorimotor integration, speech, sleep, and sense of self) that are disrupted across mood, psychosis, and autism spectrum disorders. It will further test the relevance of EEG microstates as dimensional functional biomarkers. Trial registration ClinicalTrials.gov Identifier NCT06045897.

Purpose: An interview is a form of verbal communication that utilizes prosody to influence the heuristics of listeners, in which quick and guided understanding is realized. To date, this sort of heuristics coupled with prosody information (HP) is not fully researched. This study attempts to explore how HP is organized to affect the fast judgment of listeners that grantees the desired communication in the context of WTO debate interviews. Method: This study builds a corpus of interview videos from WTO official website on WTO rules. A threshold value of acoustic sound is employed to automatically segment HP from common prosodies. These HPs are further classified into 9 categories. The distribution of specific HP showing the availability and scarcity of heuristics is done with Kurt Function. Conclusion: This study finds that the prosody is closely related to heuristics, and is constructed into heuristic prosody to impact the communication by guiding listeners’ judgment and understanding. Self-efficacy is the most prosodized heuristic in WTO interviews. Implication: Educational and training organizations, media interviewers, and interviewees who focus on the impact of communicative effects through acoustic cues may improve speakers’ performance with the practice of HP and ensure the expected communicative effect in interviews.
