Title: The Efficacy of Robot Assisted Group Cognitive Training in Elderly Adults Without Cognitive Impairment
Brief Summary: Previous studies about cognitive intervention targeting older adults revealed that cognitive training had effects on the improvement of cognitive function.However, researches are rare that investigated direct changes of brain structures after cognitive training.

The advanced scientific technique allowed us to develop service robots designed to assist human work, which can be important with an increase in the aging population and high costs of elderly care. In this regard, the investigators considered robots for elderly's cognitive training and developed 17 cognitive programs in collaboration with Center for Intelligent Robotics at Korea Institute of Science and Technology.

The purposes of this study were to demonstrate the effects of the investigators newly developed robot assisted group cognitive training programs on the brain in older adults and to identify whether they can help to improve cognitive function or mood in the elderly compared to the conventional cognitive training or control group that were not involved in any cognitive training.
