Describe the evidence that pain perception is not entirely dependent on physical injury
Each individual have experience pain differently. This is usually due to the factors of ethnicity, genetics and sex. This is known as pain perception. Different pain experiences are usually based on the location and severity of pain of an injury. However, evidence has shown that pain perception is not entirely dependent on physical injury; when pain perception is less/greater than expected from the extent of a physical injury, cases where the site of injury and site of pain differs.
Pain perception can be less than might be expected from the extent of a physical injury. This was proven by a scientist called Susana Bantick, Oxford University, and colleagues who carried out a study on the influence of attention distracting pain processing (Bantick et al, 2002). During the experiment, brain processing was measured by measuring brain activity using fMRI. Participants rated pain from 1-10 when noxious heat stimulus was applied to their hand in the scanner. She then followed the same process but gave them a task which required cognitive processing; reducing the amount of focused attention on pain. Bantick, therefore, showed attention distraction can reduce the amount of pain perceived by the individual, also pain processing to the brain was reduced. This provides vital evidence that pain perception does not just depend on the injury alone.
Another study has proven pain perception can be less
