According to Broadbent's filter model of attention, which of the following sequences is correct?

  • A.Sensory registration, Attention, Selective filter, Perceptual process, STM
  • B.Attention, Sensory registration, Selective filter, Perceptual process, STM
  • C.Sensory registration, Attention, Perceptual process, Selective filter, STM
  • D.Attention, Sensory registration, Perceptual process, Selective filter, STM

Answer: B

The keyed answer is attention, sensory registration, selective filter, perceptual process, short-term memory. In Broadbent's filter model, input arrives at sensory registration, a selective filter passes only one channel, and the perceptual process then works on it before short-term memory. The other options reorder these, but I could not confirm why the key puts attention first, so this follows the official key. The point of the filter model is that attention selects one channel early, before meaning is analysed, and only the selected channel reaches short-term memory.
