Are You Excited Yet? Anxiety as “Excitement” to Improve Performance

Alison Wood Brooks

Alison Wood Brooks

People can improve task performance in public speaking, mathematical problem solving, and karaoke singing, by reappraising anxiety as “excitement,” according to Harvard’s Alison Wood Brooks.

Using silent self-talk messages (“I am excited”) or reading self-direction messages (“Get excited!”) fosters an “opportunity mind-set” by increasing alignment between physical arousal and situational appraisal.

Jeremy Jamieson

“Excitement” is typically viewed as a positive, pleasant emotion that can improve performance, according to Harvard’s Jeremy Jamieson and colleagues.

In contrast, anxiety drains working memory capacity, and decreases self-confidence, self-efficacy, and performance before or during a task, according to Michael W. Eysenck of University of London.

Despite these differences, anxiety and excitement have similar physiological arousal profiles, but different effects on performance.

Michael Eysenck

Efforts to transform anxiety into calmness can be ineffective due to the large shift from negative emotion to neutral or positive emotion and from physiological activation to lower arousal levels, noted Brooks.

Such efforts to calm physiological arousal during anxiety can result in a paradoxical increase in the suppressed emotion, reported Stefan Hofmann and colleagues of Boston University.
However, most people in Woods’ studies said they believed that this is the best way to handle anxiety.

Stanley Schachter

Physiological similarities can confuse experiences of anxiety and excitement, demonstrated in studies by Columbia’s Stanley Schacter and Jerome Singer of SUNY.
Anxiety’s similarity to excitement can be used to relabel high “anxiety” as “excitement.”
This shift can mitigate anxiety’s negative impact on performance.

Brooks elicited anxiety among volunteers by telling them that they their task was to present an impromptu, videotaped speech.

For some participants, she explained that it is “normal” to feel discomfort and asked them to “take a realistic perspective on this task by recognising that there is no reason to feel anxiousand “the situation does not present a threat to you…there are no negative consequences...”
She also instructed volunteers to say aloud randomly-assigned self-statements like “I am excited.”

People who stated I am excitedbefore their speech were rated as more persuasive, more competent, more confident, and more persistent (spoke longer), than participants who said “I am calm.”

Brooks evaluated peoples’ reactions to another anxiety-provoking task, performing a karaoke song for an audience, and rated by voice recognition software for “singing accuracy” based on:

  • Volume (quiet-loud),
  • Pitch (distance from true pitch),
  • Note duration (accuracy of breaks between notes).

This score determined participants’ payment for participating in the study.

Before performing, she asked participants to make a randomly-assigned self-statement:

  • “I am anxious,”
  • “I am excited,”
  • “I am calm,”
  • “I am angry.”
  • “I am sad.”
  • No statement.

Following their performance, volunteers rated their anxiety, excitement, and confidence in their singing ability.
People who said that they were “excited” had higher pulse rates than other groups, confirming that self-statements can affect physical experiences of emotion.

Volunteers who said “I am excited” had the highest scores for singing accuracy and also for confidence in singing ability.

In contrast, those who said, “I am anxious” had the lowest scores for singing accuracy, suggesting that anxiety is associated with lower performance.

Brooks elicited anxiety on “a very difficult IQ test…under time pressure” that would determine their payment for participation.
To evoke further anxiety, she concluded, “Good luck minimising your loss.”

Before the test, participants read a statement:

  • “Try to remain calm” or
  • “Try to get excited.”

Those instructed to “get excited” produced more correct answers than those who tried to “remain calm.”

Reappraising anxiety as “excitement” increased the subjective experience of “excitement” instead of anxiety, and improved subsequent performance in each of these tasks.

Stéphane Côté

Stéphane Côté

These reappraisals of physical experiences evoked an “opportunity mind-set” and a stress-is-enhancing mind-set, found University of Toronto’s Stéphane Côté and Christopher Miners.
These appraisals enabled superior performance across different anxiety-arousing situations.

In contrast, inauthentic emotional displays can be physically and psychologically demanding, and often reduce performance.

People have “profound control and influence…over…emotions,” according to Woods.
She noted that “Saying ‘I am excited’ represents a simple, minimal intervention…to prime an opportunity mind-set and improve performance…

Advising employees to say ‘I am excited’ before important performance tasks or simply encouraging them to ‘get excited’ may increase their confidence, improve performance, and boost beliefs in their ability to perform well in the future.”

to investigate whether feelings of power are associated with different outcomes in professional interviews.

Collaborating with David Dubois of INSEAD, Tilburg University’s Joris Lammers, and Derek Rucker of Northwestern University, they asked job applicants and business school admission candidates to write about a time they felt powerful or powerless.

Joris Lammers

Joris Lammers

Independent judges, who were unaware of the different instructions, rated “applicant’s” written and face-to-face interview performance.
Evaluators assigned highest scores to those who recalled power experiences.

Derek Rucker

Derek Rucker

Judges preferred power-primed applicants, citing their greater persuasiveness and confidence.
These candidates received more offers of job roles and business school admission than those who wrote about powerless experiences or situations unrelated to feelings of power and powerlessness.

Sian Beilock

An earlier post highlighted Sian Beilock’s investigation of writing as a coping tool in stressful academic situations.
Her collaborators at University of Chicago, Vanderbilt, and Pace Universities showed that students could manage test anxiety by writing about their concerns to maintain a calm mindset.

Recalling an experience of personal power can influence impressions of persuasiveness, competence, and likeability in professional interviews.
This effect can be enhanced by writing about power experiences to increase confidence and optimism when working toward desired goals.

Anxiety Undermines Negotiation Performance

Maurice Schweitzer

Maurice Schweitzer

Anxious negotiators make lower first offers, end negotiations earlier, and earn lower profits than calmer negotiation counterparts.

 Harvard’s Alison Wood Brooks and Maurice E. Schweitzer of University of Pennsylvania found that these negotiations patterns occurred due to participants’ “low self-efficacy” beliefs.

Alison Wood Brooks

Alison Wood Brooks

Brooks and Schweitzer induced anxious feelings or neutral reactions during “shrinking-pie” negotiation tasks.
Negotiators who reported feeling anxious expected to achieve lower profits, presented more cautious offers, and responded cautiously to proposals by negotiation counterparts.

Negotiators who achieved better outcomes managed their emotions with strategies including:

Julie Norem

Julie Norem

  • Strategic optimism, by calmly expecting positive outcomes, according to University of Miami’s Stacie Spencer and Julie Norem of Wellesley,
  • Reattribution, by considering alternate interpretations of events.

Approaches with mixed results include:

  • Andrew Elliot

    Andrew Elliot

    “Self-handicapping”, defined as creating obstacles to explain poor outcomes and preserve self-esteem, according to University of Rochester’s Andrew Elliott and Marcy Church of St. Mary’s University,

  • Defensive pessimism, marked by high motivation toward achievement coupled with negative expectations for future challenges, leading to increased effort and preparation, according to Wellesley College’s Julie Norem and Edward Chang of University of Michigan.
Edward Chang

Edward Chang

Norem and Cantor concluded that defensive pessimists performed worse when told that that they could expect to perform well on anagram and puzzle tasks.

Defensive pessimism among university students was related to lower self-esteem, higher self-criticism, more pessimism, and frequent discounting of previous successful performances, according to Norem and Brown’s Jasmina Burdzovic Andreas.

Jasmina Burdzovic Andreas

Jasmina Burdzovic Andreas

However, they also found that self-esteem increased to almost the same levels as optimists during university years.
Pessimists’ precautionary countermeasures may have resulted in strong performance, which built credible self-esteem.

Defensive pessimism may be an effective approach to managing anxiety and performance motivation.

Anxiety Linked to Risk of Behaving Unethically

Sreedhari Desai

Sreedhari Desai

Anxious people were more likely to act with self-interested unethical behavior in studies by University of North Carolina’s Sreedhari Desai and Maryam Kouchaki of Northwestern.

Maryam Kouchaki

Maryam Kou

Anxiety was also associated with increased threat perception and decreased concern about personal unethical actions in simulated subordinate–supervisor pairs.

Desai noted that “individuals who feel anxious and threatened can take on self-defensive behaviors and focus narrowly on their own basic needs and self-interest.
This can cause them to be less mindful of principles that guide ethical and moral reasoning – and make them rationalize their own actions as acceptable
.”

Charles Carver

Charles Carver

Engaging in unethical behaviors may offer more options and greater control over outcomes, found University of Miami’s Charles Carver and Michael Scheier of Carnegie Mellon.
Unethical behavior was also associated with feelings of greater autonomy and influence, particularly in ambiguous situations, according to Ohio State’s  Roy Lewicki.

Michael Scheier

Michael Scheier

People who violate ethical norms can experience a cheater’s high‘ instead of guilt, found University of Washington’s Nicole E. Ruedy and Celia Moore of London Business School.

Roy Lewicki

Roy Lewicki

Cheaters in Ruedy’s research reported emotional uplift and self-satisfaction instead of guilt, and Paul Ekman of University of California, San Francisco referred to this exuberance among some cheaters as “duping delight.”

Nicole Ruedy

Nicole Ruedy

In Ruedy’s studies, nearly 180 people completed a four-minute anagram task to earn $1 for every correctly unscrambled word.
Participants then rated current feelings from positive to negative, both before and after the task.

Celia Moore

Celia Moore

Volunteers’ actual answers on the task were compared from imprints between their answer sheets to determine which participants reported inaccurate results.

More than 40% of these volunteers wrote in additional answers to increase their earnings, and reported significantly positive feelings after cheating on the task.

Even when Ruedy’s team told volunteers that researchers knew participants may be providing inaccurate reports in an insoluble anagram task, more than half the participants reported implausibly high scores.

Cheaters had higher levels of positive affect even when confronted with the team’s awareness of their potential deceit.
They also showed higher levels of self-satisfaction and feeling clever, capable, accomplished, satisfied, and superior.

Earning more money didn’t add to the “cheater’s high,” suggesting a top threshold for positive feelings associated with cheating.

These findings suggest that organizational leaders can increase employee quality-of-life and diminish unethical workplace behaviors by clarifying roles, which reduces anxiety.

Leaders also can reduce employees’ anxiety by:

Emotional Awareness Enables Focus, Risk-taking Even When “Stressed”

Jeremy Yip

Jeremy Yip

Greater emotional understanding enables people to quell the “incidental emotion” of anxiety while they focus on decisions, according to Wharton’s Jeremy Yip and Stéphane Côté of University of Toronto.

Stéphane Côté

Stéphane Côté

Incidental emotions that influence decision-making have been called “the affect heuristic” by University of Oregon’s Paul Slovic, Melissa Finucane of the East-West Center, Ohio State’s Ellen Peters, and Donald MacGregor, then of Decision Research.

Paul Slovic

Paul Slovic

People with greater emotional intelligence can separate unpleasant thoughts and feelings from decision making and are less likely to show the affect heuristic bias in risky decisions.

Sigmund Freud

Sigmund Freud

Sigmund Freud considered this ability to separate unpleasant thoughts and feelings as a defense mechanism deployed unconsciously to reduce anxiety and preserve self-esteem.
He called this experience “isolation,” contrasted with “compartmentalization,” which he defined as separating unpleasant emotions from each other.

Roy Baumeister

Roy Baumeister

Florida State’s Roy F. Baumeister, with Karen Dale then of Case Western, and Baruch College’s Kristin L. Sommer, documented recent studies that demonstrate “isolation” as a defense mechanism or coping strategy to contain negative feelings, “emotional contagion,” and “spillover.”

John Mayer

John Mayer

Yip and Côté demonstrated the relationship among emotional intelligence, evoked anxiety and propensity to make riskier choices in their lab studies of more than 100 volunteers, who completed the Mayer-Salovey-Caruso Emotional Intelligence Test developed by Yale’s Peter Salovey and David R. Caruso with John D. Mayer of University of New Hampshire.

David R Caruso

David R Caruso

One group received an anxiety-provoking assignment:  One minute to prepare a videotaped speech shown to peers studying “academic and social standing” at the university.
The other group was given a less stressful assignment:  Prepare a grocery list.

Volunteers in both groups could choose their compensation for participating in the study: Receive $1, or take a one in 10 chance to receive $10.

Melissa Finucane

Melissa Finucane

For those given the stressful speech-writing task, people who scored higher on emotional intelligence chose the riskier option to receive $10 three times as often as those who scored lower on emotional intelligence.

In contrast, volunteers who completed the low-stress task made similar choices for compensation no matter the level of emotional intelligence.

Ellen Peters

Ellen Peters

However, people can learn emotional awareness skills to enable mental focus and contain unrelated incidental emotions, according to related studies by Yip and Côté.

They demonstrated this ability to contain anxiety when some volunteers in the speech-writing task were told they “might feel worried” because making a speech is an anxiety-producing task.
Other speech-creators received no further instructions.

Kristin Sommer

Kristin Sommer

Yip and Côté “primed” no emotion among some grocery list-creators by saying that they “may feel no emotion” or no instructions.
Participants were then primed to separate their emotions from their decision-making by being told that their emotions were irrelevant to their decisions.

 Volunteers read information about the benefits of receiving flu injections and consequences of no inoculation during flu season.
Then participants were given the option to register for nearby flu injection clinic.

The reminder that emotions were irrelevant to decisions changed previous results, by increasing the frequency that participants with lower emotional awareness chose the riskier option of not attending the flu injection clinic.

 The findings suggest that adults can reduce emotional bias in decision-making by explicitly identifying emotions and separating them from critical thinking processes

Questions that enable people to separate emotions, thoughts, and decisions include:

  • How do I feel right now?
  • What is causing me to feel that way?
  • And are my feelings relevant to the decision I need to make?

-*How do you avoid the affect heuristic when making decisions?

Evidence-Based Stress Management – Physical Exercise – Part 5 of 5

Michael Hopkins-David Bucci

Michael Hopkins-David Bucci

“The positive stress of exercise prepares cells and structures and pathways within the brain so that they’re more equipped to handle stress in other forms,” argue Michael Hopkins, FC DavisMichelle VanTieghemPaul Whalen and David Bucci of Dartmouth.

Michelle VanTieghem

Michelle VanTieghem

They compared effects of a single exercise session or repeated sessions on non-exercising volunteers who were genotyped to determine brain-derived neurotrophic factor (BDNF), a nerve growth factor important in long-term memory.

Paul Whalen

Paul Whalen

Participants were measured on novel object recognition (NOR) memory and mental health dimensions before and after engaging in a 4-week exercise program or a single exercise session.

More frequent exercisers performed better on object recognition memory and said they experienced less stress, but only when their 4 week program included a final test.
In contrast, a single exercise session did not affect recognition memory and resulted in increased perceived stress levels.

This study found no relationship between exercise-induced cognitive benefits and changes in mood and anxiety, suggesting that perceived stress is controlled by a different neural system.

Timothy Schoenfeld

Timothy Schoenfeld

In contrast, Princeton’s Timothy Schoenfeld, Pedro Rada, Pedro Pieruzzini, Brian Hsueh, and Elizabeth Gould, reported different results with mice.
They investigated the paradox of exercise:  It promotes new, excitable brain cells that can aid learning and memory, yet exercise can induce calm in various brain areas.

Elizabeth Gould

Elizabeth Gould

Schoenfeld and team controlled for pre-existing nervousness in adult mice and allowed half to exercise and half to remain sedentary over a six week period.

Exercisers were more willing to cautiously explore and spend time in open areas, suggesting they were more confident and less anxious than their sedentary counterparts.

Brian Hsueh

Brian Hsueh

The runners’ brains developed new, excitable neurons in the hippocampus’ ventral region, associated with processing emotions and releasing GABA, which inhibits brain activity such as the subjective experience of anxiety.

All animals encountered the physical stress of cold water for five minutes, and showed many immediate early genes indicating neuron firing.
However, the runner rats calmed more rapidly due to their release of GABA after this physical stress.

Though this study was conducted with animals, the findings suggest that physical exercise builds capacity to recover more rapidly from stress by regulating anxiety through ventral hippocampus inhibition.

Brett Klika

Brett Klika

Like other stress management recommendations, regular exercise is difficult for many to adopt as an habit.
For reluctant exercisers, Brett Klika and Chris Jordan of Human Performance Institute offer a rapid but challenging solution: “Seven Minutes of Steady Discomfort.”

Chris Jordan

Chris Jordan

Their Scientific 7-Minute Workout includes 12 exercises using a chair, wall and body weight, for interval training alternating large muscles in the upper and lower body.
Each exercise is performed for 30 seconds, at a discomfort rating of 8 on a scale of 1 to 10, with a 10 second rest between.
Though quick, this routine may not be easy, and further willpower may be needed to adopt this approach.

Kirsten Burgomaster

McMaster University’s Kirsten BurgomasterKrista Howarth, Stuart PhillipsMaureen MacDonaldSL McGeeMartin Gibala with Mark Rakobowchuk now of Brunel University validated Klika and Jordan’s proposed Seven Minutes of Discomfort.

Stuart Phillips

They noted that even a few minutes of training at an intensity approaching maximum capacity produces molecular changes within muscles comparable to those of several hours of endurance training like running or bike riding.

John Salamone

Motivational help may be available by activating nucleus accumbens dopamine, which can regulate motivation and lead to goal initiation and persistence, according to University of Connecticut’s John Salamone and Mercè Correa of Universitat Jaume I of Castellón.

Mercè Correa

Mercè Correa

They refined the common assumption that dopamine is associated with reward systems and noted that nucleus accumbens dopamine, involved in appetitive and aversive motivational processes, may provide a biochemical approach to managing motivation and task persistence.

Though it may be difficult to muster the motivation to exercise regularly, these research findings suggest that regular exercise can lead to increased coping and cognitive abilities.

Evidence-Based Stress Management – Social Support – Part 3 of 5

George Vaillant

George Vaillant

Personal relationships and social support have been shown to buffer the negative effects of stress inside and outside the workplace, according to George Vaillant, then of Harvard, with colleagues SE MeyerKenneth Mukamal, and Stephen Soldz.

Kenneth Mukamal

Kenneth Mukamal

They evaluated data from a 50-year prospective multivariate study of 223 men and found that engaging with others during a stressful event improves mood, but withdrawing from others increases anxiety, depression, and stress.
In this sample, friends seemed more important than closeness to spouse and to children for sustained physical health.

Lawrence Fisher

Lawrence Fisher

Social  relationships that buffer stress and anxiety include family closeness and connectedness, problem-focused family coping skills, clear family organization, explicit decision making, and direct communication  according to University of California, San Francisco’s Lawrence Fisher and Karen Weihs of University of Arizona.

Stephen Soldz

Stephen Soldz

In contrast, lack of social connections can increase both stress and susceptibility to disease agents due to alterations in the neuroendocrine system, according to Vaillant and team.

Karen Weihs

Karen Weihs

Undermining relationship characteristics include hostility, criticism, and blame within the family; family perfectionism and rigidity; and psychopathology, according to Fisher and Weihs.

Stress-reducing social support can come from animal companions, according to SUNY Buffalo’s Karen AllenBarbara Shykoff, and Joseph Izzo, who demonstrated that “nonevaluative social support” from animal companions reduces blood pressure in response to mental stress.

Joseph Izzo

Joseph Izzo

Forty-eight hypertensive volunteers were assigned to random comparison groups:  One group had animal companions in addition to an anti-hypertensive medication (angiotensin-converting-enzyme inhibitor or ACE inhibitor) and the other group received medication only.

Before participants received medication, volunteerss in both groups had similar physical responses to stress, measured by blood pressure, heart rate, and plasma renin activity.

Allen, Shykoff, and Izzo monitored these physical indicators after experimental mental stressors (serial subtraction and speech), compared with baseline measures.
They found that although medication alone lowers resting blood pressure, social support from animal companions was associated with lower blood pressure in response to mental stress.

Mark Ellenbogen

Mark Ellenbogen

Like some other stress management recommendations, this research-based finding requires willingness, and commitment to engage with others when it may seem easier and more appealing to be alone.

Oxytocin may promote seeking social support when experiencing stress and the impulse to withdraw from others, shown in research by Concordia University’s Mark Ellenbogen and Christopher Cardoso.

Christopher Cardoso

Christopher Cardoso

They demonstrated that oxytocin can increase a person’s trust in others following social rejection.
Volunteers received oxytocin nasal spray or a placebo, then experienced experimentally-induced social rejection when confederates challenged, interrupted, and ignored the participants.

Volunteers who inhaled oxytocin before the experimental social rejection and who reported greater distress on mood and personality questionnaires also said they generally invest greater trust in other people.
In contrast, oxytocin had no effect on trust among volunteers who were not bothered by the evoked social rejection.

These findings suggest that oxytocin may help individuals experiencing stress access the benefits of social support and may become an additional stress management option.

Evidence-Based Stress Management – Vitamins, Probiotics – Part 1 of 5

The majority of U.S. adults experience significant anxiety and stress each day, often compounded by the use of multiple electronic devices, cognitive overload, and “social comparison” when participating in social media.

Amy Arnsten

Amy Arnsten

General stress and anxiety can negatively affect work performance because it can undermine prefrontal cognitive abilities and eventually lead to architectural changes in prefrontal dendrites, according to Yale’s Amy Arnsten.

John Medina of Seattle University concurred, noting that prefrontal cortex structural damage occurs when catecholamines and glucocorticoids are released during stress experiences.

John Medina

John Medina

He amplified Arnsten’s findings by linking these substances to declines in processing language and math, working memory, and attention regulation as well as to increased fear conditioning and memory for negative emotional states.

Stress management recommendations abound, and this series of five blog posts reviews research evidence supporting suggestions that usually require commitment and willpower, such as eliminating multi-tasking and reducing internet usage.

Michael Roizen

Michael Roizen

If reducing media usage is an unappealing prospect, heavy users can cite  Michael Roizen‘s findings at Cleveland Clinic, that the internet can be a vehicle for stress management.
He reported that internet-based stress management programs are effective.

Two familiar nutritional suggestions have been reconfirmed in recent research:  Include vitamins as well as probiotics (beneficial bacteria) found in fermented foods such as yoghurt, kefir, sauerkraut, tempeh, soft cheese, miso, sourdough bread, sour pickles or supplements.

Bonnie Kaplan

Bonnie Kaplan

University of Calgary’s Bonnie Kaplan validated claims that vitamin and mineral supplements can enhance mental energy, manage stress, enhance mood and reduce fatigue for those prone to anxiety and depression as well as for healthy adults.

Kaplan found that among 97 adults with diagnosed mood disorders, higher vitamin and mineral intake over three days were significantly correlated with enhanced mood, better mental functioning and reduced stress.

Sara-Jayne Long

Sara-Jayne Long

David Benton

David Benton

Similarly, Sara-Jayne Long and David Benton of University of Swansea showed that people who took a multivitamin pill for a month experienced a 68 percent reduction in anxiety and perceived stress, but not depression, fatigue or confusion, in their meta-analytic review.
Supplements containing high doses of B vitamins may be more effective in improving mood states.

Kirsten Tillisch

Kirsten Tillisch

Kirsten Tillisch of UCLA and 10 collaborators demonstrated the cognitive benefits of eating foods containing probiotics.
Tillisch and team reported that women who regularly consumed probiotics in yogurt showed altered brain function in managing stress and anxiety both while in a resting state and in response to an emotion-recognition task.

Participants were women between ages 18 and 55, divided into three groups who consumed different dietary products:

  • Yogurt containing a mix of several probiotics twice a day for four weeks
  • Dairy product that looked and tasted like the yogurt but contained no probiotics
  • No fermented milk product

Functional Magnetic Resonance Imaging (fMRI) scans before and after the four-week study and found that women who consumed the probiotic yogurt were better able to modulate experimentally-induced anxiety and stress.

Participants showed decreased activity in the insula when they viewed a series of pictures of people with angry or frightened faces and matched them to other faces showing the same emotions.
In addition, volunteers had somatosensory cortex activity during the emotional reactivity task, demonstrating better stress coping.

During the resting brain scan, participants in each group showed differing activity patterns in the brainstem’s periaqueductal grey area and the prefrontal cortex, confirming the impact of dietary change on signals to and from the intestine to the brain.

Probiotics were associated with enhanced stress management, with the benefits popularized by journalist Michael Pollan.

For those unenthusiastic about foods containing probiotics, supplements may complement vitamins in a stress-containment program.

Genes and Neurotransmitters Influence Investment Risk-Taking: Implications for Taking Career Risks?

Camelia Kuhnen

Camelia Kuhnen

Brian Knutson

Brian Knutson

Camelia Kuhnen, then of Stanford with her Stanford colleague Brian Knutson and Vanderbilt’s Gregory Samanez-Larkin posit a small but meaningful genetic basis to risk-averse financial investing, providing a biological basis for findings that women hedge fund managers outperformed male counterparts.

Volunteers with two short serotonin transporter genes (5-HTTLPR) reported that they tend to worry, and this pattern was associated with chosing less risky investment choices.

Gregory Samanez-Larkin

Gregory Samanez-Larkin

“Short allele carriers” also showed higher levels of the personality trait “neuroticism,” but no significant difference in cognitive skills, education, or financial status.
Kuhnen estimates that less than 30 percent of variance in risk-taking is attributable to short 5-HTTLPR, and the remaining difference is derived from experience, culture, education, and social environment.

Kuhnen and Knutson reported the neural basis of financial risk taking using event-related fMRI.
They observed that the nucleus accumbens was activated before volunteers made risky choices and made risk-seeking mistakes.
In contrast, they found that the anterior insula was activated before risk-free choices and risk-aversion mistakes.

They proposed that different neural circuits are associated with differing emotions as volunteers anticipate gain or loss associated with financial choices.
This emotional activation “signature” can lead to specific investment choices, favoring or avoiding risk, and may lead to investing mistakes.

In unpublished research, Kuhnen found that short-allele carriers showed increased anxiety before making a decision in a trial-and-error risk discovery task, but reacted no differently than long-allele carriers when they observed a negative outcome.

She noted that volunteers differ in how they anticipate and react to a potential decision before they make it rather that in their reactions to actual outcomes of investment decisions.

Joan Chiao

Joan Chiao

Kuhnen, now at Northwestern collaborated with Northwestern colleague Joan Chiao to investigate the impact of both the 5-HTTLPR gene and the DRD4, gene, which regulates dopamine transmission.
These genes and their related neurotransmitters have been linked to emotional behavior, anxiety and addiction.

Their research replicated Kuhnen’s earlier finding that individuals with two short 5-HTTLPR alleles take 28% less risk than people with other combinations, and they demonstrated that the double DRD4 7 allele carriers took 25% more risk than people with other combinations.
They conclude that serotonin is associated with risk-averse investment choices, whereas dopamine is associated with riskier choices.

Kuhnen and Chiao argue that risky investment behavior shares commonalities with other risky behaviors like drug use, gambling, unsafe sex, dangerous physical and social pursuits, and more.

-*How do you determine the right amount of risk to undertake in career development and financial investing?
