Music Therapist Robot for Individuals with Cognitive Impairments Adriana Tapus University of Southern California Los Angeles USA tapus usc edu Cristian T a pus Google Inc 1600 Amphitheatre Parkway

the 1 2 percent rate for the world s population as a whole This difference is expected to increase rather than diminish so that by 2050 the number of individuals over the age 85 is projected to be three times what it is today Most of these individuals will need physical emotional and cognitive assistance In this paper we present a new system based on the socially assistive robotics SAR technology that will play the role of a music therapist and will try to provide a customized help protocol through motivation encouragements and companionship to users suffering from cognitive changes related to aging and or Alzheimer s disease We present a new system based on the socially assistive robotics SAR 3 that aims to provide a customized help protocol through motivation encouragements and companionship to users suffering from cognitive changes related to aging and or Alzheimer s disease This work aims to validate that a robotic system can establish a productive interaction with the user and can serve to motivate and remind the user about specific cognitive exercises The research work presented in this paper focuses on the study of the adaptable social interactive and cognitive aspects of robot behavior in an assistive context designed for the elderly and or individuals suffering from dementia Therefore in this work we have developed a new learning and adaptation system that allows for maximizing the user s performance on a cognitive task In addition to serving as a social and cognitive tool the robot will also be capable of providing detailed reports of patient progress to caretakers physicians and therapists In this study we aim to address the following research questions Keywords assistive robotics adaptative systems machine learning 1 INTRODUCTION The American Alzheimer s Association 2 reported that more than one million residents in assisted living residences and nursing homes have some form of dementia or cognitive impairment this population is also growing steadily The rapidly increasing number of people suffering from this disease could have a crippling effect on the healthcare services in the next few decades Alzheimer s disease is a specific form of dementia Dementia is a disorder that progressively affects the brain People with dementia may not be able to think well enough to perform daily activities such as getting dressed eating speaking etc They usually lose their ability to solve problems or control their emotions The frequency of dementia increases with age from 2 in 6569 year olds to more than 20 in 85 89 year olds While there is no cure to dementia medication and special therapy may improve symptoms or slow down the progression of the disease Non pharmacological treatments focus on physical emotional and mental activity Engagement in activities is in fact one of the key recognized means of dementia care Activities e g music therapy 1 arts and crafts help individuals with dementia and cognitive impairment to maintain their functional abilities and can enhance quality of life Other cognitive rehabilitation therapies and protocols focus on recovering and or maintaining cognitive abilities such as memory orientation and communication skills APPROACH Can elderly individuals with dementia and or cognitive impairments maintain attention to music with the help of a robot in an intervention specifically designed to promote active listening How does user performance and responses compare to those of well elderly who participated in the study and elderly how have not participated in the study What if any short term effects are there of attention training with the elderly who are suffering from dementia and or other cognitive impairments Does the music based cognitive game with the robot help the elderly individuals with dementia and or cognitive impairments to increase desirable positive behavior smiling speaking and participating in group activities 3 EXPERIMENTAL DESIGN This experiment is designed to improve the participant s attention and consists of a cognitive game called Song Discovery or Name That Tune by finding the right button for the song pressing it and saying the name of the song A physical robot and or simulated robot uses the following transcript We will play a new music game In it we will play a music collection of 1 2 3 or 4 songs The songs are separated by silence You will have to listen to the music and push the button corresponding to the name of the song being played Press the button marked SILENCE during the silence period between the songs The robot computer will encourage you to find the correct song 3 1 Hypotheses This work aims at testing two main hypotheses Hypothesis 1 The social robot will help in improving or maintaining the cognitive attention of individuals with dementia and or cognitive impairments through its encouragements in a specific music based cognitive game Active listening provides a potential method for engaging cognitive skills in people with Alzheimer s and or dementia Hypothesis 2 Individuals with dementia and or cognitive impairments will prefer the physical robot to the computer simulation The more physically engaging the interaction technology is the better received it is by the participant and the more effective it is in encouraging the therapeutic game A computer is the less engaging than a human like robot 4 EXPERIMENTAL RESULTS TO DATE The initial pilot experimental group consisted of 10 participants 5 male 5 female from our partner Silverado Senior Living care facility All the participants were seniors over 70 years old suffering from cognitive impairment and or Alzheimer s disease The cognitive scores given by the Standardized Mini Mental State Examination SMMSE test were the following 2 mild 1 moderate and 7 severe Due to the total unresponsiveness of 6 of the severe participants only 1 severe participant was retained for the rest of the experiments therefore having a final group of 4 participants To test the role of physical embodiment of our robot and its impact on the users the two conditions mentioned above were tested with each
