The principles that define the cognitive level of analysis.
Cognitive psychology concerns itself with the structure and functions of the mind. Cognitive psychologists are involved in finding out how human minds come to know things about the world and how it uses this knowledge.
The mind can be conceptualized as a set of mental processes that are carried out by the brain. These processes include:
- •PROBLEM SOLVING
Cognition is based on mental representations of the world, such as, images, words and concepts.
Remember people have different experiences so people’s mental representations are not universal.
One of the most fundamental principles of cognitive psychology is that human beings are information processors and that mental processes guide behaviour. Psychologists see the mind as a complex machine – rather like an intelligent, information processing machine using hardware (the brain).
The second principle of cognitive psychology is that the mind can be studied scientifically by developing theories and using a number of scientific research methods.
The third principle that defines the cognitive level of analysis is that cognitive processes are influenced by social and cultural factors. One of the first to state this was British psychologist Fredrick Bartlett, who coined the term schema, which is defined as a mental representation of knowledge.

[Week beginning Monday 8th Dec Tuesday P3-4]
[LO 2.1] Evaluate schema theory with reference to research studies.
We hold pre-stored mental representations called cognitive schemas, mental representations’.
A theory of cognitive process: schema theory.
Cognitive theorists would call “how to store knowledge” a schema, and schema theory is a cognitive theory about information processing. A cognitive schema can be defined as networks of knowledge, beliefs and expectations about particular aspects of the world.
Schema theory suggests that what we already know will influence the outcome of information processing. The idea is based on the assumption that humans are active processors of information. People do not passively respond to information. They interpret and integrate it to make sense of their experiences, but they are not always aware of it. If the information is missing, the brain fills in the blanks based on existing schemas, or simply invents something that seems to fit in. These mistakes in our interpretations are called distortions.
Schema theory and memory processes
Schema theory has been used to explain memory processes. Cognitive psychologists divide memory processes into three main stages.
- •Encoding: transforming sensory information into meaningful memory.
- •Storage: creating a biological trace of the encoded information in memory, which is either consolidated or lost.
- •Retrieval: using the stored information.Please click below to access the key powerpoint. (Ref: psychlotron.co.uk)

Assessment. Please write up an essay 750-1000 words for this learning outcome.
Key theorists: Fredrick Bartlett (1932) Anderson & Pichert (1978) Bower et al
[WB 12 Jan 2015]
[LO 2.2] Evaluate two models or theories of one cognitive process with reference to research studies.
This learning outcome asks to evaluate two models of memory. From the three models that we will investigate, please keep in ming the question only asks for two. First of all we shall look at Atkinson and Shiffrin (1968) ‘The multi store model, which by todays research methods seem simplistic, but it offered a model on how information is processed. Following, Baddeley and Hitch (1974) suggested the ‘Working memory model’, based on the multi-store model. However, they challenged the view that the STM is a single store.
Please access the link to the powerpoint that evaluates these models of memory. (ref: IBO The Cognitive Level of Analysis)
[LO 2.3] Explain how biological factors may affect one cognitive process
Memory and the brain.
For this outcome we will focus on memory as cognitive process. The key aspects to focus on are biological and memory processess. The key biological factors include the hippocampus and amygdala which are central to memory processes. The role of levels of cortisol have also been researched. The key case studies that we shall investigate are Clive wearing; we will also revisit HM. We will also be investigating the degenerative disease known as alzheimer’s and how it affects memory. You need to complete the section in your workbooks and evaluate all of the above.
Key case studies: HM; Clive Wearing.
[Lo 2.4] Discuss how social or cultural factors affect one cognitive process. [WB 2:2:15]
Cross-cultural research – the role of schooling on remembering.
Cognitive psychologists have traditionally conducted research in western countries. If one assumes that cognitive processes follow universal laws, then all humans all over the world, regardless of culture, would perform the same cognitive tasks with the same results. Following this logic, the same memory test could be applied globally. However, this is not the case. When researchers from the west performed tests with participants in non-western countries, they found that they did poorly on many tests. This was not always interpreted correctly – that is, there was a western bias in the test and it is therefore not valid when applied to another culture.
This is related to the third principle that state socio-cultural guide behaviour and the early studies by Bartlett and “The War of the Ghosts” supports this. The key theorists and studies that we will be examining is Cole and Scribner (1974) who wanted to investigate memory strategies in different cultures.
[LO 2.5] Evaluate the extent to which a cognitive process (memory) is reliable.
The cognitive process again focuses on memory. The key concept is to refer back to Bartlett’s theory of schemas (representations of knowledge) We discussed how reliable or unreliable memories can be. We know they can easily distorted. One area where the reliability of memory is crucial, but often flawed is eye-witness testimony. The legal system uses eye-witness testimony, which relies on the the accuracy of memory to decide whether a person is guilty of a crime or not. Normally, juries in a court of law take eye witness testimony very serious but, recently, the use of DNA technology has demonstrated what some psychologists have claimed for years: eye-witnesses can be wrong. Researchers such as; Elizabeth Loftus have demonstrated that memory may not be as reliable as we think. Memories may be influenced by other factors than what was recorded in the first place, due to the reconstructive nature of memory.
The key information is on the powerpoint CLOA Slides. There are two You-tube clips you can access below. We will also be watching a video Understanding Psychology; Eyewitness testimony. Online classroom limited.
Assessment. As a group project you will design and film an incident. (a crime/event) assign roles. Think about the format and the way you can use language and questions to mislead eye-witnesses.
Write an essay 750 words “Evaluate the extent to which cognitive processes are reliable. We will also be working how to upload the essays on to Google/Docs

[LO 2.6] Explain the use of technology in investigating the cognitive process.
Use of modern technology to investigate the relationship between cognitive factors and behaviour.
Neuro-imaging techniques allow researchers to obtain images of brain functioning and structures. The knowledge gathered is used to understand the relationship between cognitive processes and behaviour. There are a number of techniques , and these are continually being developed to perform even more advanced research.
Although we have previously investigated brain imaging techniques you need to be aware that the research is specific to cognitive behaviours. In groups investigate and present imaging techniques and the key studies that support. There is supporting information in your workbooks. Each group must present a powerpoint to the rest of the class.
3.2 Cognition and Emotion
Evaluate the extent to which cognitive and biological factors interact in emotion.
Evaluate one theory of how emotions may affect one cognitive process.According to brain researchers, emotions serve as a guide to evaluate how important situations are, and it is not necessarily a conscious process. Cognitive psychologists like Lazarus and Folkman have suggested that it is not the emotion as such that is important, but rather how people appraise the situation and cope with it. Cognitive appraisal is simply an interpretation. A perceived dangerous event or stimulus will result in a psychological response known as fight or flight, which prepares the individual for direct action to confront the danger or avoid it, and a cognitive appraisal of the arousal – that is, a decision about what to do, based on previous experience.Click below to access the powerpoint.
