Describe the cognitive approach in psychology. Evaluate the research methods used by a cognitive psychologist (16 marks)

The cognitive approach focuses on internal mental processes such as memory, perception and thinking. These processes occur between a stimulus and a response. As they are not directly observable, cognitive psychologists make inferences about them based on observable behaviour. This means conclusions about mental processes are drawn indirectly from what people say or do.

The approach uses theoretical models to represent internal processes. For example, the multi-store model of memory explains how information flows through different stores, including the sensory register, short-term memory and long-term memory. These models help simplify complex processes and allow psychologists to test predictions about how the mind works.

The cognitive approach is often described as machine reductionist because it compares the mind to a computer. In this analogy, the brain is the hardware and mental processes such as coding, storage and retrieval are the software. This comparison has been useful in developing an understanding of how information is processed. Another important concept is the schema, which is a mental framework developed through experience. Schemas help individuals organise information efficiently, although they can sometimes lead to errors and distortions.

The emergence of cognitive neuroscience has strengthened the approach by linking mental processes to brain activity. Techniques such as brain scanning allow researchers to observe which areas of the brain are active during specific tasks, providing a biological basis for cognitive processes.

Cognitive psychologists often utilise case studies to gain a detailed insight into internal mental processes, particularly following trauma. For example, Wilson et al. conducted a longitudinal study over 21 years, using qualitative observations and brain scans to investigate Clive Wearing, who suffered both anterograde and retrograde amnesia following a viral brain infection. Their research provided detailed insight into the effects of memory damage and supported distinctions within long-term memory, as well as aspects of the multi-store model of memory. This is a strength because case studies allow cognitive psychologists to gain rich, in-depth data about complex mental processes that would be difficult to study using controlled experiments. This has improved our understanding of how memory functions and how it can be disrupted. However, a limitation is that case studies typically focus on a single individual, meaning the findings may lack generalisability. For example, Clive Wearing’s condition is extremely rare, so the extent to which these findings can be applied to the wider population is limited. This reduces the overall validity of conclusions drawn about memory as a whole, as they may not reflect typical functioning. Therefore, while case studies provide valuable and detailed insights into cognitive processes, their lack of generalisability means they offer a limited explanation of how memory operates in the general population.

Cognitive psychologists also rely heavily on laboratory experiments to investigate mental processes. For example, research into memory often involves controlled tasks such as word list recall, where variables can be carefully manipulated. This is a strength because lab experiments allow for high levels of control, meaning cause and effect relationships can be established. The use of standardised procedures also means studies can be replicated, increasing the reliability of findings. However, a limitation is that these tasks are often artificial and lack ecological validity. Remembering word lists in a lab does not reflect how memory is typically used in everyday life. This means the findings may not accurately represent real world cognitive processes, reducing the validity of conclusions.

Another strength of the cognitive approach is its use of scientific methods, particularly through cognitive neuroscience. For example, brain scanning techniques such as fMRI allow researchers to observe brain activity during cognitive tasks. This provides objective and quantitative data, increasing the scientific credibility of the approach. It also allows psychologists to link specific mental processes to particular brain regions. However, brain scans only show correlations between brain activity and behaviour. This means it is difficult to establish cause and effect, as increased activity in a brain area does not necessarily mean it is responsible for the behaviour. Therefore, while cognitive neuroscience enhances the scientific nature of the approach, it cannot fully explain the complexity of mental processes.
