UNDERSTANDING THE CONCEPTS PERIPERSONAL SPACE, BODY SCHEMA AND BODY IMAGE

Sammanfattning: This study will look into to the concepts of Peripersonal Space, The Body Schema and The Body Image. It examines how the terms are typically used and describes the various views about the concepts found in the literature, as well as the contradictions between these views. In the section “The Difficulty to Differentiate the Concepts” the reader gets a deeper understanding of which criteria researchers use to differentiate the concepts from one another. The fact that there are changes in kineamethic model and sensation in humans when they are using a rake is proposed as support for the idea that also the body schema is involved in tool use. In differentiating the Body schema – Body Image from each other (and other types of body representation) we come to the conclusion that positive definitions about different representations is needed and that researchers should unite their views what the definitions should be. We also mention a problem based on the possibility on infinite body representations and a solution by a Bayesian model is proposed that looks at the input as well as the output in experiments.
