Abstract

Objective

This study aims to investigate how cognitive impairment and social presence influence goal attainment in an ecological virtual environment. It also examines the role of interactive features in improving computer-assisted cognitive training for older adults, both with and without mild cognitive impairment (MCI).

Materials and Methods

A virtual supermarket was used to simulate a realistic exploration task, incorporating social interactions and adaptive assistance strategies. Error analysis was conducted to identify performance patterns linked to cognitive profiles.

Results

Participants with MCI exhibited a significantly higher frequency of wandering and uncorrected orientation errors, compared to cognitively healthy older adults. While verbal support was beneficial in facilitating virtual task progress, it did not fully mitigate performance deficits in those with MCI. Additionally, all older participants, regardless of cognitive status, reported significantly lower perceptions of social presence compared to younger participants.

Conclusion

Virtual environments constitute a promising tool for the assessment and enhancement of functional abilities in older adults with neurocognitive impairments. The integration of tailored cognitive training protocols and adaptive support strategies holds potential to optimize cognitive stimulation and task performance.

期刊介绍： IRBM is the journal of the AGBM (Alliance for engineering in Biology an Medicine / Alliance pour le génie biologique et médical) and the SFGBM (BioMedical Engineering French Society / Société française de génie biologique médical) and the AFIB (French Association of Biomedical Engineers / Association française des ingénieurs biomédicaux). As a vehicle of information and knowledge in the field of biomedical technologies, IRBM is devoted to fundamental as well as clinical research. Biomedical engineering and use of new technologies are the cornerstones of IRBM, providing authors and users with the latest information. Its six issues per year propose reviews (state-of-the-art and current knowledge), original articles directed at fundamental research and articles focusing on biomedical engineering. All articles are submitted to peer reviewers acting as guarantors for IRBM''s scientific and medical content. The field covered by IRBM includes all the discipline of Biomedical engineering. Thereby, the type of papers published include those that cover the technological and methodological development in: -Physiological and Biological Signal processing (EEG, MEG, ECG…)- Medical Image processing- Biomechanics- Biomaterials- Medical Physics- Biophysics- Physiological and Biological Sensors- Information technologies in healthcare- Disability research- Computational physiology- …
