Robot personality for cognitive training

Robots are becoming more present in our daily activities and in particular in the health context. To improve the human-robot interaction in a training session it is important to design and develop social behavior and personality in robots. Recent studies found that personality is an essential feature for creating socially assistive robots. For this purpose, I want to investigate if the robot personality (extrovert or introvert) can improve the user's cognitive performances in elders with Mild Cognitive Impairments during one-o-one cognitive training.
