Final answer:
Flat affect and catatonia could be considered native symptoms if you are referring to 'negative' symptoms, specifically in the context of schizophrenia. The term 'native symptom' is not commonly used in psychology. It could be interpreted as 'negative' symptoms in mental health disorders.
Step-by-step explanation:
The term 'native symptom' is not commonly used in psychology.

They relate to the presence or absence of behaviors, with positive symptoms being behaviors that are added to a person's normal behavior, and negative symptoms being behaviors that are lacking. The options you provided (a. flat affect b. sleep c. depression d. catatonia) seem to be different symptoms often associated with mental disorders.
