- Define Cognitive neuroscience.
- The examination of cognitive processes in the brain.
- Define Cognitive psychology
- the study of the processes by which the sensory input is transformed, reduced, elaborated, stored, recovered, and used.
- What is artifical intellegence?
- A branch of computer science that attempts to produce computer programs that can perform intellectually demanding tasks.
- What is Broadbent known for?
- The filter model
- 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?
-
TASK SIMILIARITY
They had people respond to either Audio or Visual stimulus and detect audio or visual stimulus.
A/V ; V/A = easy A/A ; V/V = hard - 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 is the Stoop effect.
-
Purpose: show automatic skills.
It takes longer for people to read through a list of colored words if the color and the word are not the same
(example red writting with blue ink) - What does the Kahnema & Henik experiment prove?
- Attention matters in the skill automatic function, not reading. You don't read the word yet you still process it.
- 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
