You Look But Do You See? Observing Accurately and Understanding Perspective

PSYCHOLOGY AND SCIENCE OF COGNITION  Workshop – Speaker Katie's Notes


Students record their visual observations of the classroom (timed, 10 minutes).

  • How many things did you observe? 
  • Did you both see the same things?
  • Did you notice the same things when you first entered the room? What was different? Was anything the same?
  • Did the exercise become easier or more difficult as time went on?


Students close eyes while new objects are placed around the room. Record changes (timed, 5 minutes)

  • How many new items are there?
  • What are they?

Discuss the reasons why certain items were seen while others were missed - placement, size, color


Discuss binocular vision and how it works.

  • What changes when you use only one eye?
  • Why do some animals have forward facing eyes while others have eyes on the sides of their head?


Discuss perspective and learn how to visually measure objects with sight sticks.

  • What is it?
  • How do you know how far away objects are? How accurate is your perception?
  • Standing up, sitting on the floor, and standing on chairs: How did objects’ angles change?


Discuss two-dimensional and three-dimensional.

  • What are the differences?
  • Can you draw an object that is 2D? An object that is 3D?


Discuss 1 point and 2 point perspective. 

  • Terms: horizon line, vanishing point, orthogonal lines, transversal lines
  • How-to drawing lesson

Optional homework:
When in a familiar environment (such as your bedroom), take a moment to look around and see if there are things in the room you don’t normally notice. Then take a pencil or a ruler (or any implement that can be used as a sight stick) and hold it up to different objects in the room. Try to find the different perspectives and vanishing points.
