This workbook is aimed at readers who interact with people with intellectual disabilities in their daily lives, whether professionally or privately. Often, questions arise about how to understand their behavior, why they cannot learn certain things, and why educational attempts frequently fail. The book aims to help readers see exactly what constitutes a person's intellectual disability and what their prerequisites are for navigating the world and their own bodies. In direct engagement with them, the focus is on learning to comprehend and describe how they experience themselves and their environment, as well as the abilities and deficits they have compared to us non-disabled individuals in their efforts to cope with life's challenges. A central theme is the sensomotor foundation of intelligence development, which is the basis of our abilities conveyed through senses and movement.
