What is the Triesman & Geffen Experiment for?
Purpose: Attenuation model.
87% tapped for the correct word on the attended side
8% tapped for the correct word on the unattended side.
Kahneman is famous for what?
The capacity model: there is a specific amount of attention which can be used depending on the state of arousal. If this is exceded then a mechanism has to allocate attention to the different tasks.
What did Allport and colleges do?
They showed that capacity depends on the SIMILARITY of the task. Experiment: shadow auditorily while being presented with A:words B:pictures.
Results: A:Poor B:Excellent

What experiment did Triesman & Davies do?

What did Sullivan do?
Task Difficulty:
It was easier to do the dichotic listening task when there was simple message shadowing going on than complex shadowing.
What did Schneider & Shiffrin show?
They showed that if the distrators are in a different category (Consistent Mapping) then set size and memory size has little effect on the performance. If the distractors are in the same category (Varible Mapping) They do, and it takes longer as the sets get bigger.
What does the instance theory state?
The competition between memory and calculation occur with activities such as 2 + 5 =7; If we were asked this before we could simply say 7 w/o calculations; however if can't remember or it will take alot of time to remember we just recalculate it
