A primary way in which psychologists assess an individual's self-schema would be to

A) examine how that person perceives and uses information presented to them.
B) use neuroimaging studies to assess how the brain functions in different situations.
C) engage in naturalistic observations of the individual in different settings.
D) employ a personality questionnaire like the MMPI.

Psychologists typically assess an individual's self-schema by examining how that person perceives and uses information presented to them. This can be done through interviews, questionnaires, or other methods of self-report, where the individual's cognitive processes regarding self-relevant information can be observed and analyzed. Neuroimaging studies, naturalistic observations, and personality questionnaires may provide useful information, but they are not primary ways to assess an individual's self-schema.
