Q

What does Broadbent’s early selection filter theory suggest?

A
  1. Our ability to process information is capacity limited
  2. A temporary buffer system receives all information and passes it to a selective filter.
  3. Selection is based on physical characteristics of information - one source is selected and others are rejected.
