Final answer:
During the Facial Recognition Task (FLT), visual sensory areas, integrating areas, and motor areas are active in the brains of both East Asians and European Americans. Neuroimaging studies reveal that up to 80 percent of the brain may be utilized, with cultural differences influencing brain activity. fMRI and PET scans are commonly used to study these neural patterns.
Step-by-step explanation:
When East Asians and European Americans perform the Facial Recognition Task (FLT), several areas of the brain are recruited. In such cognitive tasks, visual sensory areas become activated, as people visually process faces. The integrating areas of the brain work to combine different types of sensory information to form a cohesive understanding of the visual stimuli. Furthermore, the motor areas responsible for moving the eyes and the motor areas needed to press a button are engaged during this task.
Studies using functional magnetic resonance imaging (fMRI) show that diverse brain regions are activated during such tasks, debunking the myth that we use only 10 percent of our brain. In fact, it is suggested based on blood flow analysis that about 80 percent of the brain may be utilized during well-defined activities. It is important to note that these brain activities occur while the body remains mostly stationary in an MRI machine, without taking into account language responses or autonomic functions.
Cultural differences have also been noted in neurological responses to such tasks. For example, research by Masuda and Nisbett among others has demonstrated variation in information processing based on cultural backgrounds. In these scenarios, neuroimaging techniques like fMRI and PET scans provide insight into the complex dynamics and cultural influences on brain function during tasks such as the FLT.
