Cognitive modelling
Fichas del conjunto (17)
- 1What are benefits & disadvantages of using models?Pros: Formal specification of a theory(working code), gives something concrete to discuss about(code), make predictions, understanding by building
Cons: - 2What are the benefits of models for industry/practice?Usability test, trying out models "in the wild"
Have human-like experiences
Make apropriate decisions due to understanding of user - 3What is a unified theory of cognition?Develop one theory that can describe (almost) all facets of human behaviuos. Describe interactions between theories of different domains/situations/components
- 4What is difference between cognitive model and cognitive architecture?The architecture sets the framework of that has a funtion and a structure. Within this framework it is then possible to model a specific task or process
- 5What is relationship of cognitive models and architectures with strong/weak AI, Turing machine, over & under constrained theoryTuring machine and strong AI are theories that have architectures that surpass human cognition. In order to build models that do tasks in a "human way" it is needed to constrain the underlyting theorys. Under constrained leads to a more powerful architecture. Over constrained leads to weaker.
- 6What are different levels of abstraction, their characteristics, benefits, disadvantages (Newell and Marr perspective)Newell: Abstraction different time spans. From ms to months and years.
Marr: Abstraction in terms of different aspects of behavior. - 7Describe each of Marr’s 3 levels(C&P)Computational: why do we do what we do?
Algorithmic: how is a computational theory implemented?(detailed algorithms)
Implementation: what is the physical implementation?(neuoscience, where in the brain a process occurs) - 8What was Marr’s criticism of cognitive systems that were not rooted in CL?(C&P)That the goal of those systems would be mimicry and not understanding.
- 9What are limitations of CL?(C&P)CL explations does not take into account the mechanism and process that it demands. Therefore, the theories CL makes have limited predictive utility. Also cant measure response time when conducting a experiment
- 10What are limitations of IL?(C&P)Hard to understand higher cognitive processes at the neural level. Given action at neural level it is difficult to "reverse inference" back a related cognitive-level process
- 11What is the value of tying the CL or IL to the ARL?(C&P)To degrade the optimal solution to a suboptimal which corresponds more to a human-like performance
- 12What is the value of specifying a model in a cognitive architecture(C&P)The architecture gives a cognitive system with interacting functional components. A mordel in this architechture can therefore make use of all three levels
- 13Describe each of Newell’s 4 bands. How do they relate to time units and systems?Biological(ms) - basic cognition, muscle movements
Cognitive(s) - dial number, say sentence
Rational(min) - Drive to store, find gas station
Social(days,months) - Keep in touch with friends and family - 14What is the decomposition thesis?Claims that learning occurring at the social band can be reduced to learning occurring at lower bands
- 15What is the relevance thesis?Claims that instructional outcomes at the social band can be improved by paying attention to cognition at lower bands
- 16What is the modeling thesis?It says that cognitive modeling provides a basis for bridging between events on the small scale and desired outcomes on the large scale
- 17Why is the “unit-task” level useful for each thesis?It is useful for assessing the theses
