This document discusses perception, communication, and their importance for facilitating collaboration and learning. It makes three key points:
1) Perception is how our brain receives, processes, and interprets information from our senses, while communication involves transmitting and receiving signs, data, and knowledge between individuals.
2) For facilitating groups, it is important to consider both the individual spaces of perception as well as the common space where individuals learn together through cooperation.
3) The quality of cooperation depends on the quality of communication, as individuals working together rely on communicating their goals, methods, roles, and building a shared body of knowledge over time.
