Auditory Selective Attention

HideShow resource information

1. What does Treisman's attenuation theory not entail?

  • The meaning is extracted after the attenuation process
  • The filter distinguishes information on physical differences
  • One of the inputs is allowed through the filter based on its physical characteristics
  • The filter is an attenuator which reduces the impact of the unattended channel

2. How did Broadbent not account for his findings?

  • This filter prevents overloading the limited capacity of the mechanism which processes input for meaning
  • Two stimuli presented at the same time gain access in parallel to a sensory buffer
  • All information from both channels is attended and processed semantically
  • The sensory buffer is the point at which stimuli is filtered

4. In Treisman's study, the Czech text in the unattended channel was read with an English accent. How many participants detected this characteristic?

  • 8/30
  • 4/30
  • 25/30
  • 11/30

5. What does Deutsch and Deutsch's model not entail?

  • The late filter distinguishes information on physical differences
  • Irrelevant information is filtered out at the time of STM storage
  • Both channels are processed to the same degree
  • Meaning of the information is extracted before the filtering process takes place
