Over the course of the CODE-V project, a comprehensive research programme was implemented to investigate heritage language development among Turkish speakers in Norway and Turkey. The work began with a thorough preparation phase, including obtaining ethical approvals, selecting and adapting background questionnaires, and developing experimental materials and visual stimuli in collaboration with a professional animator. Pilot studies with monolingual participants were conducted to refine the experimental design.
Data collection was carried out in both Turkey and Norway, resulting in a robust sample of monolingual and heritage speakers, both adults and children. While the use of an online experimental platform enabled remote participation, data from child participants were collected in person to ensure reliability. All procedures adhered to ethical standards, including informed consent and GDPR-compliant data handling. Minor challenges in recruiting heritage adults were successfully overcome through extended outreach and collaboration with community centres.
Advanced statistical modelling techniques were applied to both offline and online (eye-tracking) data, focusing on how speakers process grammatical cues such as case marking, word order, and prosody. The analyses revealed important developmental and cross-linguistic patterns in heritage language processing. While most tasks were completed as planned, one analysis task was postponed and will be addressed in future work.
Dissemination activities exceeded expectations, with findings presented at numerous international conferences and workshops. Several manuscripts are in preparation or have been submitted to leading journals, and outreach activities were conducted at community centres in Oslo, East London, and Stockholm.
Training and career development were integral to the project, with regular meetings, seminars, and workshops contributing to professional growth. The fellow completed training in experimental platforms and open science practices, and participated in a Norwegian language course to facilitate community engagement.
Project management was strengthened through regular meetings with the supervisor and advisory board, careful planning and budgeting, and the recruitment and coordination of collaborators across multiple countries.
All major deliverables and milestones were achieved, and the project has made significant contributions to scientific understanding, educational practice, and policy relevant to heritage language maintenance and multilingualism.
