In the piolt experiment, a team of two visual communication designers was asked to design a video film. Findings show that private imagery experiences remain only partially accessible to the team members, and these inadequacies have serious implications for the synergy of the teamwork. Access to each other's descriptions and sketches was insufficient for understanding the details and richness of their personal imagery experiences. The vital details, such as understanding of the size, scale, proportion, and 3-D movement of the objects, background music, and lighting conditions, were seldom communicated, making way for ambiguity and assumptions. Both designers had to share the effort to discuss and sketch while continuing their mental involvement in creative efforts. Besides the personalization of the language-imagery relationship, the vagueness of the sketches made access to other people’s imagery more difficult.
