Questions and Answers
What role does the amygdala play in decision-making, according to De Martino et al. (2010)?
What role does the amygdala play in decision-making, according to De Martino et al. (2010)?
The amygdala acts as a 'cautionary brake' in decision-making, relating to loss aversion.
How did participants instructed to engage in emotion regulation perform in terms of loss aversion?
How did participants instructed to engage in emotion regulation perform in terms of loss aversion?
They showed reduced loss aversion due to decreased amygdala responses to losses.
What was the primary finding of Studer et al. (2015) regarding patients with damage to the ventromedial prefrontal cortex?
What was the primary finding of Studer et al. (2015) regarding patients with damage to the ventromedial prefrontal cortex?
Patients with damage showed greater risk appetite and poorer risk adjustment compared to healthy controls.
In what way does the ventromedial prefrontal cortex influence decision-making under risk?
In what way does the ventromedial prefrontal cortex influence decision-making under risk?
What were the implications of Sokol-Hessner et al.'s (2013) findings on emotion regulation and decision-making?
What were the implications of Sokol-Hessner et al.'s (2013) findings on emotion regulation and decision-making?

Amygdala's role in loss aversion
Amygdala's role in loss aversion
The amygdala acts as a cautionary brake in decision-making, influencing our responses to potential losses.
Emotion regulation and loss aversion
Emotion regulation and loss aversion
Reducing emotional involvement in decision-making tasks can decrease loss aversion, potentially by decreasing amygdala responses to losses.
Ventromedial Prefrontal Cortex (vmPFC) and risk-taking
Ventromedial Prefrontal Cortex (vmPFC) and risk-taking
Damage to the vmPFC results in elevated risk-taking, particularly when the probability of success is low, impacting both gains and losses.

Study Notes
Brain Areas and Risky Decision-Making
- Amygdala damage eliminates loss aversion. This suggests the amygdala acts as a cautionary signal in risky decisions.
- Emotion regulation reduces loss aversion. This is likely because emotion regulation decreases amygdala responses to losses.
- Damage to the ventromedial prefrontal cortex leads to elevated risk-taking, especially when the probability of success is low.
- Studer et al. (2015) found patients with ventromedial prefrontal cortex damage had increased risk appetite (particularly when risky actions were disadvantageous) compared to healthy controls.
- Patients with ventromedial prefrontal cortex damage showed poor risk adjustment (adjusting bets based on winning probabilities).
- Poor risk adjustment and risk appetite in patients with ventromedial prefrontal cortex damage led to poor overall decision-making in their betting performance.
- The ventromedial prefrontal cortex is key for risk processing and successful risk-based decisions.
