162-458: A diagnosis and the selection of appropriate treatment. But naturalistic decision-making research shows that in situations with higher time pressure, higher stakes, or increased ambiguities, experts may use intuitive decision-making rather than structured approaches. They may follow a recognition-primed decision that fits their experience, and arrive at a course of action without weighing alternatives. The decision-maker's environment can play

243-417: A two-alternative forced choice task involving rhesus monkeys found that neurons in the parietal cortex not only represent the formation of a decision but also signal the degree of certainty (or "confidence") associated with the decision. A 2012 study found that rats and humans can optimally accumulate incoming sensory evidence, to make statistically optimal decisions. Another study found that lesions to

324-404: A belief or a course of action among several possible alternative options. It could be either rational or irrational. The decision-making process is a reasoning process based on assumptions of values , preferences and beliefs of the decision-maker. Every decision-making process produces a final choice , which may or may not prompt action. Research about decision-making is also published under

405-405: A decision turned out to be sub-optimal). The psychologist Daniel Kahneman , adopting terms originally proposed by the psychologists Keith Stanovich and Richard West, has theorized that a person's decision-making is the result of an interplay between two kinds of cognitive processes : an automatic intuitive system (called "System 1") and an effortful rational system (called "System 2"). System 1

486-501: A decision-making process called GOFER, which they taught to adolescents, as summarized in the book Teaching Decision Making To Adolescents . The process was based on extensive earlier research conducted with psychologist Irving Janis . GOFER is an acronym for five decision-making steps: In 2007, Pam Brown of Singleton Hospital in Swansea , Wales , divided the decision-making process into seven steps: In 2008, Kristina Guo published

567-498: A decrease in the amount of gray matter in the ventromedial prefrontal cortex. The decrease in gray matter and effect on behavior is analogous to a person having lesions throughout their medial prefrontal cortex. Specifically, the pyramidal cells of the ventromedial prefrontal cortex are known to be linked with drug seeking behaviors . Both an increased and decreased level of activity in these pyramidal cells has shown to lead to extinction of cocaine-seeking behaviors depending on when

648-836: A greater risk to health than they thought), but do not differ from adults in their ability to alter beliefs in response to good news. This creates biased beliefs, which may lead to greater risk taking. Adults are generally better able to control their risk-taking because their cognitive-control system has matured enough to the point where it can control the socioemotional network, even in the context of high arousal or when psychosocial capacities are present. Also, adults are less likely to find themselves in situations that push them to do risky things. For example, teens are more likely to be around peers who peer pressure them into doing things, while adults are not as exposed to this sort of social setting. Biases usually affect decision-making processes. They appear more when decision task has time pressure,

729-419: A group improves the quality of decisions, while the majority of opinions (called consensus norms) do not. Conflicts in socialization are divided in to functional and dysfunctional types. Functional conflicts are mostly the questioning the managers assumptions in their decision making and dysfunctional conflicts are like personal attacks and every action which decrease team effectiveness. Functional conflicts are

810-719: A lack of logic or reasoning, but more due to the immaturity of psychosocial capacities that influence decision-making. Examples of their undeveloped capacities which influence decision-making would be impulse control, emotion regulation, delayed gratification and resistance to peer pressure . In the past, researchers have thought that adolescent behavior was simply due to incompetency regarding decision-making. Currently, researchers have concluded that adults and adolescents are both competent decision-makers, not just adults. However, adolescents' competent decision-making skills decrease when psychosocial capacities become present. Research has shown that risk-taking behaviors in adolescents may be

891-474: A part in the decision-making process. For example, environmental complexity is a factor that influences cognitive function. A complex environment is an environment with a large number of different possible states which come and go over time. Studies done at the University of Colorado have shown that more complex environments correlate with higher cognitive function, which means that a decision can be influenced by

972-578: A person's decision-making process depends to a significant degree on their cognitive style. Myers developed a set of four bi-polar dimensions, called the Myers–Briggs Type Indicator (MBTI). The terminal points on these dimensions are: thinking and feeling ; extroversion and introversion ; judgment and perception ; and sensing and intuition . She claimed that a person's decision-making style correlates well with how they score on these four dimensions. For example, someone who scored near

1053-500: A sense of reward from risk-taking behaviors, their repetition becomes ever more probable due to the reward experienced. In this, the process mirrors addiction . Teens can become addicted to risky behavior because they are in a high state of arousal and are rewarded for it not only by their own internal functions but also by their peers around them. A recent study suggests that adolescents have difficulties adequately adjusting beliefs in response to bad news (such as reading that smoking poses

1134-406: A single choice about how to face the problem. Although these steps are relatively ordinary, judgements are often distorted by cognitive and motivational biases, include "sins of commission", "sins of omission", and "sins of imprecision". Herbert A. Simon coined the phrase " bounded rationality " to express the idea that human decision-making is limited by available information, available time and

1215-755: Is "a gap between the volume of information and the tools we have to assimilate" it. Information used in decision-making is to reduce or eliminate the uncertainty. Excessive information affects problem processing and tasking, which affects decision-making. Psychologist George Armitage Miller suggests that humans' decision making becomes inhibited because human brains can only hold a limited amount of information. Crystal C. Hall and colleagues described an "illusion of knowledge", which means that as individuals encounter too much knowledge, it can interfere with their ability to make rational decisions. Other names for information overload are information anxiety, information explosion, infobesity, and infoxication. Decision fatigue

1296-423: Is a bottom-up, fast, and implicit system of decision-making, while system 2 is a top-down, slow, and explicit system of decision-making. System 1 includes simple heuristics in judgment and decision-making such as the affect heuristic , the availability heuristic , the familiarity heuristic , and the representativeness heuristic . Styles and methods of decision-making were elaborated by Aron Katsenelinboigen ,

1377-449: Is a correlation between emotional disregulation and dysfunction in real world competencies. The amygdala plays a significant role in instigating the emotional reactions associated with anger and violence. With the vmPFC’s outputs to the amygdala, the vmPFC plays a part in preventing such behavior. Evidence has shown that impulsive murderers have decreased activity in the prefrontal cortex and increased activity in subcortical areas such as

1458-406: Is a multi-step process for making choices between alternatives. The process of rational decision making favors logic, objectivity, and analysis over subjectivity and insight. Irrational decision is more counter to logic. The decisions are made in haste and outcomes are not considered. One of the most prominent theories of decision making is subjective expected utility (SEU) theory, which describes

1539-415: Is another occurrence that falls under the idea of extinction by instinct. Groupthink is when members in a group become more involved in the “value of the group (and their being part of it) higher than anything else”; thus, creating a habit of making decisions quickly and unanimously. In other words, a group stuck in groupthink is participating in the phenomenon of extinction by instinct. Information overload

1620-558: Is complementary to decision-making. See also mental accounting and Postmortem documentation . Decision-making is a region of intense study in the fields of systems neuroscience , and cognitive neuroscience . Several brain structures, including the anterior cingulate cortex (ACC), orbitofrontal cortex , and the overlapping ventromedial prefrontal cortex are believed to be involved in decision-making processes. A neuroimaging study found distinctive patterns of neural activation in these regions depending on whether decisions were made on

1782-434: Is done under high stress and/or task is highly complex. Here is a list of commonly debated biases in judgment and decision-making : In groups, people generate decisions through active and complex processes. One method consists of three steps: initial preferences are expressed by members; the members of the group then gather and share information concerning those preferences; finally, the members combine their views and make

1863-417: Is generally seen as the best or most likely decision to achieve the set goals or outcome. It has been found that, unlike adults, children are less likely to have research strategy behaviors. One such behavior is adaptive decision-making, which is described as funneling and then analyzing the more promising information provided if the number of options to choose from increases. Adaptive decision-making behavior

1944-496: Is similar but more severe. It is also considered central to the physiology of anxiety and mood disorders. However, the precise mechanisms by which vmPFC contributes to affective processing are not fully understood. Patients with bilateral lesions of the vmPFC develop severe impairments in personal and social decision-making even though most of their intellectual ability is preserved. For instance, they have difficulties in choosing between options with uncertain outcomes, whether

2025-405: Is somewhat present for children, ages 11–12 and older, but decreases in presence the younger they are. The reason children are not as fluid in their decision making is because they lack the ability to weigh the cost and effort needed to gather information in the decision-making process. Some possibilities that explain this inability are knowledge deficits and lack of utilization skills. Children lack

2106-423: Is still highly debated as there are many MCDA methods which may yield very different results when they are applied to exactly the same data. This leads to the formulation of a decision-making paradox . Logical decision-making is an important part of all science-based professions, where specialists apply their knowledge in a given area to make informed decisions. For example, medical decision-making often involves

2187-450: Is that more complex principles of fairness in decision making such as contextual and intentional information do not come until children get older. During their adolescent years, teens are known for their high-risk behaviors and rash decisions. Research has shown that there are differences in cognitive processes between adolescents and adults during decision-making. Researchers have concluded that differences in decision-making are not due to

2268-477: Is the process of investigating the given information and finding all possible solutions through invention or discovery. Traditionally, it is argued that problem solving is a step towards decision making, so that the information gathered in that process may be used towards decision-making. When a group or individual is unable to make it through the problem-solving step on the way to making a decision, they could be experiencing analysis paralysis. Analysis paralysis

2349-440: Is the state that a person enters where they are unable to make a decision, in effect paralyzing the outcome. Some of the main causes for analysis paralysis is the overwhelming flood of incoming data or the tendency to overanalyze the situation at hand. There are said to be three different types of analysis paralysis. On the opposite side of analysis paralysis is the phenomenon called extinction by instinct. Extinction by instinct

2430-416: Is the state that a person is in when they make careless decisions without detailed planning or thorough systematic processes. Extinction by instinct can possibly be fixed by implementing a structural system, like checks and balances into a group or one's life. Analysis paralysis is the exact opposite where a group's schedule could be saturated by too much of a structural checks and balance system. Groupthink

2511-422: Is when a sizable amount of decision-making leads to a decline in decision-making skills. People who make decisions in an extended period of time begin to lose mental energy needed to analyze all possible solutions. Impulsive decision-making and decision avoidance are two possible paths that extend from decision fatigue. Impulse decisions are made more often when a person is tired of analysis situations or solutions;

2592-419: The lateral hypothalamus , the hippocampal formation , the cingulate cortex , and certain other regions of the prefrontal cortex . This huge network of connections affords the vmPFC the ability to receive and monitor large amounts of sensory data and to affect and influence a plethora of other brain regions, particularly the amygdala. Functional differences between the orbitofrontal and ventromedial areas of

2673-594: The ACC in the macaque resulted in impaired decision-making in the long run of reinforcement guided tasks suggesting that the ACC may be involved in evaluating past reinforcement information and guiding future action. It has recently been argued that the development of formal frameworks will allow neuroscientists to study richer and more naturalistic paradigms than simple 2AFC decision tasks; in particular, such decisions may involve planning and information search across temporally extended environments. Emotion appears able to aid

2754-513: The DECIDE model of decision-making, which has six parts: In 2009, professor John Pijanowski described how the Arkansas Program, an ethics curriculum at the University of Arkansas , used eight stages of moral decision-making based on the work of James Rest : There are four stages or phases that should be involved in all group decision-making: It is said that establishing critical norms in

2835-528: The ability of patients with vmPFC lesions to categorize gender-specific names, attributes, and attitudes compared to patients with dorsolateral prefrontal cortex lesions and control subjects. Whereas the patients with dorsolateral prefrontal cortex lesions performed similarly to the control subjects on tests indicating gender stereotypes, patients with ventromedial prefrontal cortex lesions demonstrated impaired stereotypic social knowledge. Frequent cocaine users have been shown to have lower than normal activity in

2916-402: The activation takes place. Inactivation of these cells was needed to inhibit cocaine-seeking behavior after a longer duration of time, whereas activation was required to reduce the behavior soon after using cocaine. Decision-making In psychology , decision-making (also spelled decision making and decisionmaking ) is regarded as the cognitive process resulting in the selection of

2997-410: The amygdala, being associated with a decrease in cortisol levels. It should also be noted that damage to the vmPFC can promote higher amygdala activity. There are only a few reports of people with early-onset vmPFC damage during childhood, but these individuals tend to have severe antisocial behavior and impaired moral judgment. Compared to individuals with damage later in life, their behavior pattern

3078-528: The amygdala. This imbalance can enhance actions that are created by negative emotions and limit the ability of the prefrontal cortex to control these emotions. Lower activation in the prefrontal cortex is also correlated with antisocial behavior. The dysfunction of the ventromedial cortex seems to, in part, be caused by lower levels of serotonin release. The vmPFC also is involved in courage. In experiments with participants allowing snakes to come near or away from them, acts of courage correlated with activation in

3159-406: The basis of perceived personal volition or following directions from someone else. Patients with damage to the ventromedial prefrontal cortex have difficulty making advantageous decisions. A common laboratory paradigm for studying neural decision-making is the two-alternative forced choice task (2AFC), in which a subject has to choose between two alternatives within a certain time. A study of

3402-405: The boundaries of the area. Different researchers use the term ventromedial prefrontal cortex differently. Sometimes, the term is saved for the area above the medial orbitofrontal cortex , while at other times, 'ventromedial prefrontal cortex' is used to describe a broad area in the lower (ventral) central (medial) region of the prefrontal cortex, of which the medial orbitofrontal cortex constitutes

3483-412: The capture of material (the main constituent element of a chess position). The objective is implemented via a well-defined, and in some cases, unique sequence of moves aimed at reaching the set goal. As a rule, this sequence leaves no options for the opponent. Finding a combinational objective allows the player to focus all his energies on efficient execution, that is, the player's analysis may be limited to

3564-457: The cognitive-control network changes more gradually. Because of this difference in change, the cognitive-control network, which usually regulates the socioemotional network, struggles to control the socioemotional network when psychosocial capacities are present. When adolescents are exposed to social and emotional stimuli, their socioemotional network is activated as well as areas of the brain involved in reward processing. Because teens often gain

3645-440: The decision-making process. Human performance has been the subject of active research from several perspectives: A major part of decision-making involves the analysis of a finite set of alternatives described in terms of evaluative criteria. Then the task might be to rank these alternatives in terms of how attractive they are to the decision-maker(s) when all the criteria are considered simultaneously. Another task might be to find

3726-402: The decision-making process. Decision-making often occurs in the face of uncertainty about whether one's choices will lead to benefit or harm (see also Risk ). The somatic marker hypothesis is a neurobiological theory of how decisions are made in the face of uncertain outcomes. This theory holds that such decisions are aided by emotions, in the form of bodily states, that are elicited during

3807-436: The degree of extinction memory. Patients with larger vmPFCs tended to have lower responses to the extinct conditioned stimulus, therefore suggesting a superior extinction memory. In general, the ventromedial prefrontal cortex plays a major role in the later stages of memory consolidation . Ventromedial prefrontal cortex lesions were also associated with a deficit in processing gender specific social cues. One experiment tested

3888-431: The deliberation of future consequences and that mark different options for behavior as being advantageous or disadvantageous. This process involves an interplay between neural systems that elicit emotional/bodily states and neural systems that map these emotional/bodily states. A recent lesion mapping study of 152 patients with focal brain lesions conducted by Aron K. Barbey and colleagues provided evidence to help discover

3969-494: The dorsolateral PFC is associated with vulnerability to depression. The right half of the ventromedial prefrontal cortex was associated with regulating the interaction of cognition and affect in the production of empathic responses. Hedonic (pleasure) responses were also associations to orbitofrontal cortex activity level by Morten Kringelbach . This finding contributes findings suggesting ventromedial prefrontal cortex being associated with preference judgement, possibly assigning

4050-529: The founder of predispositioning theory . In his analysis on styles and methods, Katsenelinboigen referred to the game of chess, saying that "chess does disclose various methods of operation, notably the creation of predisposition-methods which may be applicable to other, more complex systems." Katsenelinboigen states that apart from the methods (reactive and selective) and sub-methods randomization , predispositioning, programming), there are two major styles: positional and combinational. Both styles are utilized in

4131-423: The game of chess. The two styles reflect two basic approaches to uncertainty : deterministic (combinational style) and indeterministic (positional style). Katsenelinboigen's definition of the two styles are the following. The combinational style is characterized by: In defining the combinational style in chess, Katsenelinboigen wrote: "The combinational style features a clearly formulated limited objective, namely

4212-569: The idea that the ventromedial prefrontal cortex is an important component for reactivating past emotional associations and events, therefore essentially mediating pathogenesis of PTSD. Dysfunction of the vmPFC has also been identified as playing a role in PTSD-affected parents' response to their own children's mental states. Treatments geared to the activation of the ventromedial prefrontal cortex were therefore suggested for individuals and parent-child relationships affected by PTSD. The right half of

4293-579: The label problem solving , particularly in European psychological research . Decision-making can be regarded as a problem-solving activity yielding a solution deemed to be optimal, or at least satisfactory. It is therefore a process which can be more or less rational or irrational and can be based on explicit or tacit knowledge and beliefs. Tacit knowledge is often used to fill the gaps in complex decision-making processes. Usually, both of these types of knowledge, tacit and explicit, are used together in

4374-453: The left hemisphere. One particularly notable theory of vmPFC function is the somatic marker hypothesis , accredited to António Damásio . By this hypothesis, the vmPFC has a central role in adapting somatic markers—emotional associations, or associations between mental objects and visceral (bodily) feedback—for use in natural decision making. This account also gives the vmPFC a role in moderating emotions and emotional reactions because whether

4455-441: The location. One experiment measured complexity in a room by the number of small objects and appliances present; a simple room had less of those things. Cognitive function was greatly affected by the higher measure of environmental complexity, making it easier to think about the situation and make a better decision. It is important to differentiate between problem solving , or problem analysis, and decision-making. Problem solving

4536-494: The lowermost part. This latter, broader area, corresponds to the area damaged in patients with decision-making impairments investigated by António Damásio and colleagues (see diagram, and below). The ventromedial prefrontal cortex is connected to and receives input from the ventral tegmental area , amygdala , the temporal lobe , the olfactory system , and the dorsomedial thalamus . It, in turn, sends signals to many different brain regions including; The temporal lobe, amygdala,

4617-441: The metacognitive knowledge necessary to know when to use any strategies they do possess to change their approach to decision-making. When it comes to the idea of fairness in decision making, children and adults differ much less. Children are able to understand the concept of fairness in decision making from an early age. Toddlers and infants, ranging from 9–21 months, understand basic principles of equality. The main difference found

4698-530: The mind's information-processing ability. Further psychological research has identified individual differences between two cognitive styles: maximizers try to make an optimal decision , whereas satisficers simply try to find a solution that is "good enough". Maximizers tend to take longer making decisions due to the need to maximize performance across all variables and make tradeoffs carefully; they also tend to more often regret their decisions (perhaps because they are more able than satisficers to recognize that

4779-450: The neural mechanisms of emotional intelligence . Decision-making techniques can be separated into two broad categories: group decision-making techniques and individual decision-making techniques. Individual decision-making techniques can also often be applied by a group. A variety of researchers have formulated similar prescriptive steps aimed at improving decision-making. In the 1980s, psychologist Leon Mann and colleagues developed

4860-509: The pieces directly partaking in the combination. This approach is the crux of the combination and the combinational style of play. The positional style is distinguished by: "Unlike the combinational player, the positional player is occupied, first and foremost, with the elaboration of the position that will allow him to develop in the unknown future. In playing the positional style, the player must evaluate relational and material parameters as independent variables. ... The positional style gives

4941-441: The player the opportunity to develop a position until it becomes pregnant with a combination. However, the combination is not the final goal of the positional player – it helps him to achieve the desirable, keeping in mind a predisposition for the future development. The pyrrhic victory is the best example of one's inability to think positionally." The positional style serves to: According to Isabel Briggs Myers ,

Research in developmental neuroscience also suggested that neural networks in the ventromedial prefrontal cortex are rapidly developing during adolescence and young adulthood supporting emotion regulation through

5103-456: The product of interactions between the socioemotional brain network and its cognitive-control network . The socioemotional part of the brain processes social and emotional stimuli and has been shown to be important in reward processing . The cognitive-control network assists in planning and self-regulation. Both of these sections of the brain change over the course of puberty . However, the socioemotional network changes quickly and abruptly, while

5184-399: The rational behavior of the decision maker. The decision maker assesses different alternatives by their utilities and the subjective probability of occurrence. Rational decision-making is often grounded on experience and theories that are able to put this approach on solid mathematical grounds so that subjectivity is reduced to a minimum, see e.g. scenario optimization . Rational decision

5265-482: The rationality of these considerations is from the point of view of the person themselves, so a decision is not irrational just because someone else finds it questionable. In reality, however, there are some factors that affect decision-making abilities and cause people to make irrational decisions – for example, to make contradictory choices when faced with the same problem framed in two different ways (see also Allais paradox ). Rational decision making

5346-503: The right vmPFC showed a loss of empathy and theory of mind , showing that the brain regions is directly involved in empathy and mentalizing . The capacity for mature defense mechanisms such as intellectualization, compensation, reaction formation, and isolation has been tied to proper functioning of the right ventromedial prefrontal cortex, while more primitive defense mechanisms such as projection, splitting, verbal denial, and fantasy have been found to rely on other regions, primarily in

5427-425: The solution they make is to act and not think. Decision avoidance is when a person evades the situation entirely by not ever making a decision. Decision avoidance is different from analysis paralysis because this sensation is about avoiding the situation entirely, while analysis paralysis is continually looking at the decisions to be made but still unable to make a choice. Evaluation and analysis of past decisions

5508-470: The uncertainty is in the form of a risk or of an ambiguity. After their lesion, these patients have an impaired capacity to learn from their mistakes, making the same decisions again and again even though they lead to negative consequences. These patients choose alternatives that give immediate rewards , but seem to be blind to the future consequences of their actions. However, the underlying mechanisms of this behavior are not yet fully understood. Damage to

5589-422: The ventrolateral prefrontal cortex, being active during emotion regulation, was activated when participants were offered an unfair offer in a scenario. Specific deficits in reversal learning and decision-making have led to the hypothesis that the ventromedial prefrontal cortex is a major locus of dysfunction in the mild stages of the behavioral variant of frontotemporal dementia . A study of patients with lesions in

5670-416: The ventromedial prefrontal cortex (especially in the right hemisphere) has been connected with deficits in detecting irony , sarcasm , and deception . Subjects with damage in this area have been found to be more easily influenced by misleading advertising . This has been attributed to a disruption of a "false tagging mechanism" which provides doubt and skepticism of new beliefs . People with damage to

5751-508: The ventromedial prefrontal cortex a key role in constructing one's self. fMRI scans have found that the vmPFC is active when people think about themselves. There are cultural differences in the use of this region based on cultural differences in self-perception. Chinese subjects who think of the self in relation to the community have been found to utilize the vmPFC when thinking about their mothers, whereas American subjects do not. Studies with post-traumatic stress disorder (PTSD) also supported

5832-508: The ventromedial prefrontal cortex are more likely to endorse self-serving actions that break moral rules or cause harm to others. This is especially true for patients whose damage occurred the earliest in life. Emotions and an understanding of social norms are used to provide reasoning of the moral nature on our behaviors, beliefs, and the people around us. The vmPFC works as the neural basis in allowing emotion to influence moral judgement. In functional imaging studies, increased activity in

5913-478: The ventromedial prefrontal cortex still retain the ability to consciously make moral judgments without error, but only in hypothetical situations presented to them. They are severely impaired in making personal and social decisions. There is a gap in reasoning when applying the same moral principles to similar situations in their own lives. The result is that people make decisions that are inconsistent with their self professed moral values. People with early damage to

5994-436: The ventromedial prefrontal cortex. When asked to perform certain tasks that rely heavily on activation of this area of the brain, the cocaine users perform worse and have less prefrontal cortex activation than the control subjects. The quantity of cocaine used was found to be inversely proportional to the level of activation. The prefrontal cortex is also physically affected by cocaine use. Chronic use has been shown to lead to

6075-405: The vmPFC after extinction training. The specific role played by the vmPFC concerning extinction is not well understood, but it is believed that it plays a necessary role in the recall of extinction learning after a long period of time. Studies show that it aids in the consolidation of extinction learning. A separate study has implicated the correlation between the cortical thickness of the vmPFC and

6156-450: The vmPFC decides the markers are positive or negative affects the appropriate response in a particular situation. However, a critical review of this hypothesis concluded that there is a need for additional empirical data to support the somatic marker theory. Another role that the vmPFC plays is in the process of extinction , the gradual weakening and eventual cessation of a conditioned response, as studies have shown increased activation of

6237-605: The vmPFC is associated with thinking of these personal moral situations, while making harmless decisions does not. Patients with vmPFC lesions made the same decision in impersonal and personal dilemmas. Dysfunction of the vmPFC causes failure in using correct moral emotion , which explains why these patients showed less emotional responses when facing these dilemmas. The vmPFC plays an important role in regulating and inhibiting our response to emotions. VmPFC seems to use our emotional reactions to model our behavior and control emotional reactions in certain social situations. The inputs of

6318-483: The vmPFC provide it with information from the environment and the plans of the frontal lobe, and its outputs allow the vmPFC to control different physiological responses and behaviors. The role of the vmPFC is especially highlighted in people with damage to this region. A damaged vmPFC causes impairments of behavioral control and decision making , consequences which are rooted in emotional dysregulation. The first and most famous case of someone with defects to this region

6399-402: The vmPFC show personality changes such as lack of empathy, irresponsibility, and poor decision making. These traits are similar to psychopathic personality traits. In addition, a correlation between individuals with a history of physical violence and decreased grey matter density in the vmPFC has been evidenced. Lesions to the vmPFC are associated with resistance to depression, whereas lesions to

Patients with vmPFC lesions show defects both in emotional response and emotion regulation. Their emotional responsiveness is generally diminished and they show markedly reduced social emotions such as compassion, shame and guilt. These are emotions that are closely associated with moral values. Patients also exhibit poorly regulated anger and frustration tolerance in certain circumstances. Patients with focal lesions in
