29
Q

brown and poultons (driving attention)

A

Two conditions

  • Drive in residential (few inputs)
  • Drive in car park (larger inputs)
  • played tape of numbers had to identify difference between sequences

30

Miller (memory)

A

Limits to people’s short term memory

Should chunk information into 7 chunks that mean something
