In research on suicide, abnormal serotonin levels and a dysfunctional depression-related brain circuit seem MOST related to:

• A. Shame
• B. Aggression
• C. Selfishness
• D. Introversion

Answer: (B)

Biological factors that regulate mood and impulse control are what connect to suicide risk. Serotonin helps regulate aggression and the ability to control impulses; when serotonin signaling is abnormal, people can become more prone to impulsive or aggressive actions, including self-directed aggression. A depression-related brain circuit that includes mood-regulating regions in the limbic system and regulatory areas in the prefrontal cortex can malfunction, leading to intensified negative mood, irritability, and poorer control over actions. Put together, these neural factors point most strongly to aggressive and impulsive tendencies as linked to suicide risk, rather than traits like shame, selfishness, or introversion, which are not the primary biological correlates highlighted by this research.
