1. What was the critical result behind Lavies perceptual load hypothesis?

  • No resources were dedicated towards target detection so pps performed equally in both tasks
  • There was a noticeable dual task decrement from only the high load condition
  • The compatibility effect only arose for the low load condition (small no of non-targets), no corresponding effect for high load condition
  • The compatibility effect only arose for the high load condition (small no of non-targets), no corresponding effect for low load condition

2. What is the central claim of late-selection theories (e.g Deutsch Deutsch, 1963)?

  • All messages are analysed to the level of response set, selection of attention based on PHYSICAL PROPERTIES. Contradicts early-selection models
  • All messages are analysed to the level of stimulus set, selection of attention based on MEANING. Contradicts early-selection models
  • All messages are analysed to the level of response set, selection of attention based on MEANING. Contradicts early-selection models
  • All messages are analysed to the level of stimulus set, selection of attention based on PHYSICAL PROPERTIES. Contradicts early-selection models

3. What is the concept of 'Categorising'?

  • Once a category is establish, members are selected on the basis of bias to the category rather than on physical features
  • Only processing events which belong to a particular category. Takes practice to establish categories/members
  • Selection of events with particular physical features = processing

4. Which of these is NOT a component of the filter model? (Broadbent, 1958)

  • A rehearsal mechanism
  • Long term store
  • Selective filter (channel selective)
  • Limited capacity channel
  • Short term store

5. What is selective attention?

  • The ability to discriminate and direct attention to different stimuli
  • A result of processing resources
  • The ability to divide attention
  • The ability to recall info from unattended channels
