| Outline of Research at the Start |
Mental representations of phonemic contrasts have been claimed to be asymmetric with a combination between specified and underspecified features. This project investigates asymmetries in mental representations and processing of lexical pitch contrasts focusing on Tokyo Japanese (a pitch-accent language), compared to Mandarin Chinese (a tone language) and German (an intonation language). Specification vs. underspecification of lexical prosody will be discussed to incorporate the findings of this project into current spoken-word recognition models, speech technology and language didactics.

| Outline of Annual Research Achievements |
1.Literature Review: I conducted an extensive review of relevant literature on phonological asymmetries, cross-linguistic studies of pitch contrasts, and electrophysiological methodologies.
(April to August 2023), 2. Experimental Design: I designed experimental paradigms for the planned two main studies, refining auditory-visual semantic priming experiments for the ERP study and developing a passive oddball paradigm for the MMN study. From this stage, I collaborated with Dr. Michele Gubian at the university of Munich, Prof. Dr. Bettina Braun and Prof. Dr. Carsten Eulitz. (August-November). 3. Stimulus Preparation: I prepared stimuli for both experiments while based in Germany, receiving valuable programming assistance from my collaborators (December - January 2024). 4. EEG Setup: I set up EEG equipment in Germany, ensuring readiness to start gathering data. This comprehensive approach demonstrates meticulous preparation and attention to detail, leveraging resources effectively in the German academic environment (January) 5. Collaboration: I collaborated with the aforementioned researchers for programming support and utilized resources at the respective universities enhancing the robustness and interdisciplinary nature of our research efforts.
Moving forward, I am poised to commence data collection and analysis, leveraging our collaborative efforts, technical expertise, and preparedness.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The literature review phase of the research project has been completed successfully. Extensive efforts were made to thoroughly review relevant literature on phonological asymmetries, cross-linguistic studies of pitch contrasts, and electrophysiological methodologies. The review provided a solid theoretical foundation for the research objectives and guided the development of experimental designs.
The experimental design phase of the project has been meticulously executed. The designs were carefully tailored to address the research questions and ensure the validity and reliability of the experimental outcomes.
Stimuli for both experiments were meticulously prepared while based in Germany, with valuable programming assistance received from Michele Gubian. The stimuli were designed to elicit specific responses relevant to the research objectives and were tailored to the linguistic characteristics of each language group.
The setup of EEG equipment was completed successfully in Germany, ensuring readiness to commence data collection. This included configuring the EEG equipment, conducting calibration tests, and preparing the experimental environment for data acquisition. The setup process was conducted with careful consideration of technical specifications and experimental requirements, laying a solid foundation for data collection and analysis.
Effective communication and collaboration with my collaborators facilitated the smooth execution of experimental procedures and enhanced the interdisciplinary nature of the research project.

| Strategy for Future Research Activity |
1) Data Collection: Commence data collection for ERP and MMN studies in Germany (Konstanz). Implement rigorous data quality control measures with the help of the group of Prof. Dr. Eulitz.
Data Analysis: Analyze EEG data using statistical methods to identify significant differences in pitch contrast processing across languages. 2)Results Interpretation: Interpret findings in the context of existing literature and theories of phonological processing. Consider practical applications in speech technology and language education. 3) Manuscript Preparation: Draft manuscripts for publication in peer-reviewed journals. Collaborate with co-authors to refine drafts and address reviewer feedback. 4)Conference Presentations: Prepare presentations for academic conferences to disseminate research findings. Engage with fellow researchers for feedback and discussion. 5)Project Documentation: Maintain comprehensive documentation of research activities. Organize project files and data systematically for future reference.6) Collaboration and Networking: Maintain collaboration with colleagues and seek interdisciplinary networking opportunities to enhance research impact. 7) Grant Applications: Identify grant opportunities to support future phases of the project. Submit applications with detailed research plans and budgetary requirements. 8)Project Review and Reflection: Conduct regular project review sessions to assess progress and adjust strategies as needed. Solicit feedback from collaborators and stakeholders.
