In order to study fear, a neuroscientist connects Natividad to an electroencephalograph (EEG) and then shows her a brief movie o
f scary animals. These include wasps, snakes, and alligators. He then observes as Natividad shows activation in her amygdala. At which level of analysis has this scientist made his observations?
Biological level, category: Physiology and Behaviour
Explanation:
According to the LOA (Levels of Analysis), this test was conducted on a biological level.
This level observes the physical features of the brain, and how its physiology change or reacts to different kinds of stimulus, thus, studying its behavior.
Physiology is the scientific study of the functions and mechanisms which work within a living system. As a sub-discipline of biology, the focus of physiology is on how organisms, organ systems, organs, cells, and biomolecules carry out the chemical and physical functions that exist in a living system.
