- Simons & Chabris
- Background
- Inattentional Blindness: failure to see event as focused on another element
- Neisser tested IB using basketball game with woman and umbrella walking through
- Aims
- Is IB more likely if unexpected event and attended event are similar
- more likely to see a particularly unusual event?
- does task difficulty have an effect?
- Effect of transparent or opaque video type
- Sample: students 228 observed but 192 analysed, given sweets or money
- IV: video type; gorilla or woman; task difficulty DV: saw unexpected event or not
- Procedure
- Instructions given to either count passes (easy) or bounces and passes (hard)
- Shown video of 2 teams playing basketball
- asked to keep score mentally and wrote it down after
- Asked if saw anything unusual and to describe it if they did
- debrief after
- Results
- Saw gorilla more likely if watching black team: white, 8 saw black, 67 saw (transparent, easy, gorilla)
- saw umbrella woman more as taller: 100 saw woman, 42 saw gorilla (opaque, easy, white)
- hard task made seeing more difficult: 67 saw gorilla with easy. 25 (transparent, gorilla, black)
- opaque video easier to see: transparent: 8 opaque: 50 (hard, gorilla, white
- Ethics: broke deception
- Ethnocentrism: dif jobs require dif attention
- Reliability & Validity
- IR: replicable of Neisser
- ER: large sample, no fluke
- IV: similar to Neisser but some could have seen before
- EV: artificial scenario
- Link to Debates: useful in court, witness could miss something
- Summary
- Cognitive: attention is cognitive
- Attention: no conscious perception wittout attnetion
