Example ScenariosCurrent Lecture Ted talk - Rebecca Saxe: How We Read Each Others Mindso Don’t study criminals, study juryo TMS to RTPJo Takes a long time to develop throughout childhood Cortical Structures Consistently Implicated in Emotional Processing (Testable)- Role of RTPJ (role of consequences)- Look past actual results and consider what the actors intentions were (not results), valence/weight persons morals or intended bad outcomeo Intended vs incidental harmo Not moral decision making part of brain, but RTPJ waits (what they intended to happen, how severely judged should they be?) Humans with Amygdala DamageThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Judgments of trustworthiness (of strangers in strange situations) are markedly skewed from normal Ventromedial PFC: Holding the Amygdala in Check- Optimizing survival and reproduction requires a balance between being paralyzed by fear and engaging in calculated risk-taking (overcome by apprehensions)o Optimum scenario is compromise between risk scenario/paralyzed fear (Darwinism)- The primary brain structure in control of extinguishing conditioned fear responses is the vmPFCo vmPFC is “reciprocally connected” with the amygdala o We can take an objective analysis, but we cant extract emotional PFC: The morality factor?- General principle of cog science:o Cortical processing is absolutely required for normal conscious experience- Motion blindness results from damage to specific areas of cortical damage (to structuresin dorsal visual stream)- Following PFC damage:o Absence of anger, sadness, pleasure etc…o Little to no empathy or regard for the rights of otherso Act zombie-ess, space cadet, become passive vmPFC Damage in Adults- Damage to vmPFC occurring in adulthood (due to disease or accident) often leaves “theoretical social judgment” abilities intact while greatly impairing ones ability to apply these judgment in real-life situations- Emotional dysregulation and instability, low frustration tolerance, heightened irritability, elevated anxiety… etc… BUT…- … NO RELATIONSHIP between cog abilities (which may be quite high) and real-world competencies (which are typically very impaired) Example Scenarios- Table 11.1 o Brownies- nonmoralo Speedboat- impersonal moral scenarioo Lifeboat- personal moral
