Two systems in brain
Reasoning vs. Emotion/Intuition
4 things of emotional system of brain
Results in a “good” or “bad” feeling
Faster: automatic and effortless
Associated with somatic (body) states (e.g., sweating)
Two parts of brain that emotional system covers
Involves amygdala and ventromedial prefrontal cortex
Cognitive system in brain
Effortful Reasoning and Cognitive Control
Utilitarian (considers costs vs. benefits)
Slower: uses attention and working memory
Resolves conflict when reason and emotion don’t agree
Suppress inappropriate or unwanted automatic behavior
Two parts of brain for cognitive system
Involves lateral prefrontal cortex and anterior cingulate cortex
Head injuries cause
ventromedial prefrontal damage
In the lab...
Patients with ventromedial damage fail to show anticipatory sweating when contemplating a decision with negative consequences
Two roles of amygdala
Role in emotional learning and responses, especially to aversive stimuli (fear)

Role in perception of fearful facial expressions

Lack of a fear response through conditioning or explicit learning

Difficulty with Fearful
Facial Expressions
Responsibilities of cog system
Detecting conflict between automatic and effortful processes
Overcoming conflict
Suppressing Inappropriate/automatic Behavior
Evidence of cog system
Anterior cingulate cortex and lateral PFC activity when there is high response conflict and errors`
Greene test results
Experiment 1 Results

People treat these dilemmas differently because the personal dilemma evokes an emotional response.
Personal and impersonal
Personal: Pushing the big guy over the bridge to stop the train
Impersonal: Hitting the switch so the train hits the man
