Attempting to learn more about the physiological aspects of depression, dr. paul observes levels and areas of brain activation in equal numbers of male and female subjects as they are viewing images of people exhibiting angry, sad, and fearful facial expressions. what is dr. paul most likely to observe? a. chances are better that 2 to 1 that the subject is male if brain activation levels are significantly suppressed. b. brain activation is markedly less in subjects diagnosed with depression. c. brain activation is significantly greater in subjects diagnosed with depression. d. chances are better that 2 to 1 that the subject is female if brain activation is significantly less than normal.

B. Brain activation is markedly less in subjects diagnosed with depression.

Explanation:

It is likely that the researcher shown in the question above realizes, based on his experiment, that brain activation is significantly less in individuals diagnosed with depression. This is because depression has the ability to "age" the brain and, consequently, decrease the synaptic density, not allowing the nervous cells to pass impulses and transmit information to each other.

For this reason, in the research shown above, people diagnosed with depression will show less brain activity, that is, less sensitivity and reaction to the images viewed by them.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
