Attention and its effects on stimulus processing - The level at which selection occurs

4 important questions on Attention and its effects on stimulus processing - The level at which selection occurs

What is early selection

Filtering out irrelevant information before the completion fo sensory and perceptual analysis

What is the broadbent model

  1. Sensory input
  2. selective filter (early selection: open or closed)
  3. limited-capacity channel
  4. higher processing and response selection
  5. response   

What is the treisman's early selection model

  1. Sensory input
  2. selective filter (early selection, relative attenuation)
  3. analysis of meaning (includes context)
  4. response

What do the more recent models propose

Sensory information might be filtered out or selected at relatively early processing stages according to basic physical characteristics such as color or pitch

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
