Introduction

• Things in the distance are pictured smaller?
• In how many directions can they get smaller?
• Depth? Answer Yes
• Very well known
• Vertical? Left/Right (horizontal)? Answer Yes
• BUT not well known!!! To be explained tonight!
• What did Esref do? What do C54 students do?

Conclusion

• Only one person converged in 3-directions like
  Esref
• 1 subject / 46 tested
• Esref converged in 3 directions with cubes
  arrayed to the left
• Sighted person converged in 3 directions with
  cubes arrayed in depth
• Drawing development peaks at 3-direction
  convergence?
