What effect does damage to the prefrontal cortex have on aggression?

• A. Improved long-term planning
• B. Heightened emotional control
• C. Increased impulsivity and focus on the present
• D. Enhanced understanding of consequences

Answer: (C)

Damage to the prefrontal cortex is associated with increased impulsivity and a heightened focus on immediate circumstances, which can lead to aggressive behaviors. The prefrontal cortex plays a crucial role in regulating emotions and controlling impulses, as it is involved in decision-making, social behavior, and the evaluation of consequences. When this area is compromised, individuals may find it difficult to inhibit their aggressive impulses and may prioritize immediate rewards over long-term consequences. This can result in more reactive and aggressive behaviors in situations where they might otherwise exhibit self-control or consider the broader implications of their actions.

In contrast, other options suggest an improvement in cognitive functions like long-term planning and understanding consequences, which are typically impaired when the prefrontal cortex is damaged. Heightened emotional control is also unlikely to result from damage to this area, as it is primarily responsible for emotional regulation and impulse control.
