Abstract
Physical activities, according to the embodied cognition theory, are an important manifestation of cognitive functions. As a result, in this paper, the Activate Test of Embodied Cognition (ATEC) system is proposed to assess various cognitive measures. It consists of physical exercises with different variations and difficulty levels designed to provide assessment of executive and motor functions. This work focuses on obtaining human activity representation from recorded videos of ATEC tasks in order to automatically assess embodied cognition performance. A self-supervised approach is employed in this work that can exploit a small set of annotated data to obtain an effective human activity representation. The performance of different self-supervised approaches along with a supervised method are investigated for automated cognitive assessment of children performing ATEC tasks. The results show that the supervised learning approach performance decreases as the training set becomes smaller, whereas the self-supervised methods maintain their performance by taking advantage of unlabeled data.
Highlights
Executive functions are higher-order mental processes that allows us to successfully plan, multitask, focus, remember instructions, and coordinate, forming the foundation of cognitive development
The main focus of this chapter is applying self-supervised visual representation learning for human activity recognition in Activate Test of Embodied Cognition (ATEC)-system recorded videos
The ATEC system includes both recording and administrative interfaces, which were designed to streamline the assessments without any interruptions
Summary
Executive functions are higher-order mental processes that allows us to successfully plan, multitask, focus, remember instructions, and coordinate, forming the foundation of cognitive development. They mostly rely on brain functions such as working memory, mental flexibility, motor skill, etc. Children affected with neurological conditions such as attention deficit hyperactivity disorder (ADHD) exhibit motor abnormalities [1,2], especially when it comes to balance. When such impairments are not treated in a timely manner, they can have an impact on a person’s daily activities. The motor system, the perceptual system, physical interactions with the environment, and the world assumptions built into the organism’s structure are all examples of physical features
