Magnetic Resonance Imaging (MRI) allows us to visualize and measure deep, primitive brain
regions involved in desire and emotion.

Key Areas
1) Development. Age-specific changes in regional brain development can impact behavioral choices.
2) Contexts. Emotionally charged contexts may lead to emotional brain regions “hijacking” prefrontal control circuitry leading to poor behavioral choices.
3) Individuals. Variation across individuals (impulsivity, sensation seeking, emotional reactivity) impacts choice behavior.

How does Regional Brain Development map onto Behavioral Development
• Hallmark of behavioral development is a gain in ability to suppress an inappropriate action in favor of an appropriate one (impulse control).
• Individual Differences• Influence of Context

ConclusionsThe behavioral and imaging studies of emotion regulation and self control provide evidence for:-significant individual and developmental differences in these abilities.-potential for change in these abilities by social and psychological contexts.

ConclusionsThe behavioral and imaging studies of emotion regulation and self control provide evidence for:-significant individual and developmental differences in these abilities.-potential for change in these abilities by social and psychological contexts.All 3 can lead to imbalances between control and emotional systems, yielding suboptimal choice behavior.and require careful consideration when considering approach for behavioral change!
