The Cognitive Approach Flashcards
What is the cognitive approach?
The term ‘cognitive’ has come to mean ‘mental processes’, so this approach is focused on how our mental processes (I.e. Thoughts) affect behaviour.
What are internal mental processes?
‘Private’ operations of the mind such as perception and attention that mediate between stimulus and response.
What is a schema?
A mental framework of beliefs and expectations that influence cognitive processing. They are developed from experience.
What is inference?
The process whereby cognitive psychologists draw conclusions about the way mental processes operate on the basis of observed behaviour.
What are the key assumptions of the cognitive approach?
- they believe that internal mental processes lie between stimulus and response
- these mental processes are not observable so cognitive psychologists study them indirectly by making inferences about them, these can be modelled and tested scientifically
- people are information processors and the mind operates in the same way as a computer
- humans actively organise and manipulate information from the environment (schemas)
What is the information processing model?
Cognitive psychologists compare the human mind to a computer (the computer analogy) arguing that there are similarities in the way that information is processed.
Like computers, human beings are information processors and so it should be possible to identify the different forms and stages of processing which explain our behaviour.
The information processing model suggests that information does through the cognitive system in a sequence of stages that include input, transformation, and output.
Many different kinds of mental processing contribute to information processing. These include selecting important information (attention), using it to solve problems (thinking), storing it retrieving it when needed (memory).
In the following example, identify the three stages of information processing:
Rob, a young man, is in a supermarket when he sees an old lady struggling to reach the top shelf for a pack of biscuits. He offers to get them down for her and then reaches up for them.
Input: seeing old woman struggling
Transformation: deciding whether to help her or not
Output: offering to help
How does the cognitive approach study these mental processes?
They study them indirectly by inferring what is going on. This enable cognitive psychologists to develop theories about the mental processes and how they work.
One way to study internal processes is through the use of theoretical models such as the information processing model.
What are theoretical models?
These models are simplified representations of mental processes based on research evidence which therefore supports a scientific approach to enquiry and testing. They are usually represented by boxes and arrows which show how information flows through the cognitive system in a sequence is stages.
Research on these models can then be carried out to confirm, refute, or modify them by testing observable behaviour using experiments.
Give an example of a theoretical model
The multi-store model
Why is the mind compared to a computer?
Because there are similarities in the way information is processed.
Cognitive psychologists use the computer metaphor to simulate human mental abilities in artificial intelligence to perform tasks that require decision making.
Give an example of a computer simulation and what it does
One early example of computer simulation is the general problem solver (GPS) that completes simple sequential puzzles such as the tower of Hanoi.
What is artificial intelligence?
It is concerned with producing machines that behave intelligently. Expert systems are programmed with a body of knowledge and then used to deal with real world problems to replace the work of humans.
Give an example of artificial intelligence
The dendral programme which has been used to help chemists to establish structure of complex molecules.
Cognitive processing can often be affected by a person’s bellies or expectations, often referred to as a schema. What is a schema?
Schemas are packages of ideas and information gathered through experience that often distort our interpretation of sensory material.
