- Background
- Cherry's Cocktail Party Effect: if you hear your name in another convo it draws your attention from your own
- Aim: rigorous, empirical test of Cherry's findings
- Pre-Test
- Found equivalent volume for each participant
- Experiment 1
- Sample: undergrads & research workers
- Procedure
- simple word list spoken into ear as shadowed or rejected message
- asked to remember any words from rejected list
- recognition task of 21 words: 7 from shadow, 7 from reject, 7 similar
- Results
- 4.9 words recognised from shadow
- 1.9 words recognised from reject
- 2.6 words 'recognised' from similar list
- Experiment 2
- Sample 12 undergrads & research workers
- IV: name given or not DV: frequency respondence to instruction
- Procedure
- 2 different passages read into each ear
- shadowed right ear unless told otherwise
- Some gave name (affective) some didn't (non-affective)
- 10 tasks with dif instructions
- Results: 20/39 affective heard; 4/36 non-affective heard
- Conclusion: more likely to hear affective instruction
- Experiment 3
- Sample: 28 in 2 groups
- IV: asked about shadow numbers DV: mean number of digits remembered
- Procedure
- asked to shadow message
- number was either in shadow or reject or both
- No significant results; numbers aren't enough to break block
- Ethics: all kept
- Conclusions
- reject can't break block if attention on shadow
- short word list can't be remembered from reject even if repeated
- important messages can break block
- difficult to make neutral material able to break block
- Ethnocentrism specie specific behaviour but language could shape different people
- Reliability & Validity
- IR: highly controlled lab setting
- ER: pattern found but sample to small & similar
- IV: possible demand characteristics
- EV: not normal in daily life
- Debates: Usefullness
- evidence for cocktail party effect, helps understandin
- Summary
- Cognitive: attention is cognitive
- Attention: see if 'unattended' material can break barrier
