CognitionThe mental processes that are involved in perception, attention, memory, problem solving, reasoning, and making decisions
Cognitive Level of AnalysisLooks at how cognition can
affect human behaviour
A brief recap….

People are active information processors We perceive and interpret what is going on around us This is often based on what we already know There is a relationship between our mental
representations and the way we perceive and think about the world
Human behaviour is determined by a set of mental tasks/processes
Mental tasks/processes include; perception, thinking, problem solving, memory, language and attention (a.k.a cognitions)
1. Human beings are information processors and mental processes guide
behaviour
![Page 27: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/27.jpg)
Cognitive psychologist see these cognitions/mental tasks as active systems
In between taking in and responding to information a number of processes are at work.
Information can be transformed, reduced, elaborated, filtered, manipulated, selected, organised, stored and retrieved
Therefore the human mind is seen as an active system processing information, and cognitive psychologists aims to study these processes.
Central to this information processing approach is the computer metaphor.

The Computer Metaphor People, like computers, acquire information from the environment
( input) Both people and computers store information and retrieve it when
applicable to current tasks Both are limited in the amount of information they can process at a
given time Both transform information to produce new information; both return
information to the environment ( output). This information processing approach can be seen in;
◦ Models of memory◦ Schema theory
(more about each of these later).

Who can remember the three principles of the cognitive level of analysis???
A brief recap
![Page 39: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/39.jpg)
1. Human beings are information processors and mental processes guide behaviour
2. The mind can be studied scientifically
3. Cognitive processes are influenced by social and cultural factors
The principles of CLOA
![Page 40: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/40.jpg)
Defines cognitive systems as mental representations of knowledge
Mental representations (schemas) are stored in categories in memory
These schemas provide guidelines for interpretation of incoming information when people try to make sense of the world
Schemas influence cognitions in that they create expectations about what will happen in certain situations
Schema theory can, to a large extent, explain reconstructive memory and stereotyping
Principle 1 demonstrated in Schema Theory
![Page 41: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/41.jpg)
Darley and Gross (1983) Performed experiment in which showed videos of a girl
playing in a poor environment and then a wealthy environment
Then saw a video of the girl in what could be an intelligent test
When the participants were asked to judge the future of the girl they all said that the ‘poor’ girl would do worse than the ‘wealthy’ girl
Study demonstrated how people actively process information based on a few salient details to form an overall impression that may not necessarily be correct
Principle 1 demonstrated in Schema Theory
![Page 42: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/42.jpg)
Cognitive researchers use a number of scientific methods to study the mind
These include lab experiments, neuroimaging, case studies, interviews and archival research
The most used method was, for a long time, the lab experiment because it was considered to be the most scientific
2. The mind can be studied scientifically
![Page 43: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/43.jpg)
Performed experiment to test reconstructive memory in relation to EWT
Aim: see whether misleading questions could distort memory Participants were shown a video of a car crash and were
asked to estimate the speed of the car based on question “how fast was the car going when it smashed/hit/bumped/contacted the other car”
The word smashed elicited higher speed estimations Because the experimental method was used it was possible
to establish a cause and effect relationship between the use of specific words and estimation of speed.
Experimental research on memory has, however, been criticised for lacking ecological validity
Principle 2 demonstrated in Loftus and Palmer (1974)
![Page 44: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/44.jpg)
Used MRI scan to observe exact damage to H.M’s brain
HM suffered from amnesia due to a brain operation where the hippocampus and adjacent areas were removed to eliminate his epilepsy
Scans confirmed damage to those areas
Principle 2 demonstrated in Corkin et al (1999)
![Page 45: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/45.jpg)
Research has shown that cognitive processes such as perception, memory and thinking are influenced by sociocultural factors
Bartlett (1932) introduced the concept of ‘cultural schema’
Suggested that schemas influence memory in that they lead to distortion or “reconstructive memory”
Other researchers suggest that the environment in which people live leads to specific cultural and social demands that influence the way that they process information
3. Cognitive processes are influenced by social and cultural factors
![Page 46: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/46.jpg)
DiMaggio (1997) suggests that schemas are: Representations of knowledge (e.g.
Stereotypes and social roles) Mechanisms that simplify cognition in the
form of ‘cognitive shortcuts’ that are shaped by culture
Schematic cognition is shaped and biased by culture (e.g. Cultural based stereotypes)
3. Cognitive processes are influenced by social and cultural factors
![Page 47: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/47.jpg)
Suggested memory is guided by schemas and culture can influence schemas
Previous knowledge determines the way people interpret incoming information and memory
He asked British participants to read an unfamiliar Native American story and reproduce it
Participants changed the details of the story to fit with their own cultural schemas
Principle 3 demonstrated in Bartlett (1932)
![Page 48: Cognitive Level of Analysis](https://reader036.fdocuments.in/reader036/viewer/2022062501/5681642d550346895dd5f4a0/html5/thumbnails/48.jpg)
