Cognitive Processes

What is Cognitive Psychology?

 How we process information about the world.

 Normally we live without examining how we experience our lives.

 Artists, engineers, product designers, entertainers must consider how we process our world – to do their jobs well.

 Consider The Rokeby Venus by Diego Velázquez (British National Gallery)

What’s wrong with this

picture?

 With the mirror in this position, it would be impossible for her to see her face.  We would see our faces or the painter’s face with the mirror at this angle.  See would see us or the painter.

 Her face is too large – it is actual size, not smaller as it would really be.

 75% of people asked said she is looking at herself.

What should the artist paint?

 Is it better to paint the woman’s own face or what would really appear in the mirror?

 Artist’s must understand how we perceive in order to paint an image that looks real.  If artists painted things the way they would really appear, the painting would look “wrong” to viewers.

Mind as a “Black Box”

Input: Sensation

Output: Behavior

What happens inside the “box” to produce the observed behavior?

Information Processing

A computer metaphor is used to

conceptualize mental activity:

 Mental processes operate upon

mental representations

“Ops on Reps”

 Flowcharted steps

A Functional Approach

Mental activity is described in

functional terms.

Brain location, brain processes

and neural representation are

ignored.

 Neuroscience allows us to test functional ideas.
