    • CORNEA

    • IRIS

    • PUPIL

    • LENS

    • RETINA

    • OPTIC NERVE

  • 1. Choose two of the 6 senses from your chart. Create a Venn Diagram comparing these two senses.

    • At least three similarities in center.

    • At least three differences on the sides.


Sensation and perception

Sensation and Perception

The Biological Basis of Behavior: Unit III


I sensation
I. Sensation

  • A. occurs anytime a stimulus activates one of the receptors in your sense organs


What if we could sense everything
What if we could sense everything?

Life would hurt…

so we can only take in a window of what is out there.


Ii perception
II. Perception

  • A. definition –The process of organizing and interpreting information our sensory information.

Don't read the words -just say the colors they're printed in, and do this aloud as fast as you can.


Iii principles of perception
III. Principles of Perception

  • 1. Stroop effect

    • Recognizing and naming colors requires more of our attention than reading.



  • 2. Gestalt

    • a. tendency to integrate pieces of information into meaningful wholes

    • b. we see patterns and groupings, instead of small, individual pieces.

  • 5. optical illusions relation to prior perceptual experiences

    • SOMETIME OUR VISUAL PECEPTION TRICKS US!


Impossible figure
IMPOSSIBLE FIGURE relation to prior perceptual experiences

This optical illusion works because we try to assign a three dimensional aspect to a two dimensional picture. The technique of perspective angles has been used.


Do you see grey dots
Do you see grey dots? relation to prior perceptual experiences

Explanation: The eye, which responds to an amazingly wide variety of light sources from moon light to direct sunlight, tries to adjust to the present light levels. In this optical illusion, the contrast between the black and white is so strong and irregular that the white ends up looking gray.


Which line is longer
Which line is longer? relation to prior perceptual experiences

This is one of the most studied optical illusions. It was created by a German psychiatrist named Franz Müller-Lyer in 1889. It is not well understood why this optical illusion works


Which box has the smaller man
Which box has the smaller man? relation to prior perceptual experiences

The tunnel creates a believable sense of perspective in this optical illusion. The second man looks bigger than it is because it seems to fill up the tunnel.


Are the lines below straight or are they curved
Are the lines below straight or are they curved? relation to prior perceptual experiences

Bell Ringer 10/29 relation to prior perceptual experiences

  • 1. What is perception?

  • 2. Yesterday we went over four different laws of perception. Describe at least two of these laws.


Iv depth perception
IV. Depth Perception relation to prior perceptual experiences

  • A. definition – the ability to see objects in three dimensions although the images that strike the retina are two dimensional.

  • B. we use perceptual clues to determine distance and depth



  • 2. Relative Size - perceive it as closer if we know that two objects are similar in size, the one that looks smaller is farther away

  • 3. Relative Height - things higher in our field of vision, they look farther away

  • 4. Linear Perspective - Parallel lines seem to converge with distance


Relative height size
Relative height & size perceive it as closer




  • Relative size dust) . Clearer objects seem closer.

  • Linear perspective

  • Aerial perspective

  • Relative height

  • Interposition
