  5. Theoretical Models of Attention

  6. Theoretical Models of Attention x x x • Broadbent (1958) conceptualized attention as information processing • Used a cuing paradigm to show that attentional selection of one channel dramatically biased perception • Believed that unattended inputs were filtered out altogether o o o x o o "Was there an x in the bottom left square?" "Was there an o in the bottom left square?"

  7. Early Selection • Early Selection model postulated that attention acted as a strict gate at the lowest levels of sensory processing • Based on concept of a limited capacity bottleneck
