Listening to up-tempo music synchronized to low- or moderate-intensity exercise can distract from fatigue and discomfort and reduce oxygen consumption, according to Sheffield Hallam University’s CJ Bacon and TR Myers, and Brunel University’s Costas Karageorghis.

They found that cyclists who listened to synchronous up-tempo music used 7% less oxygen than those who cycled in silence.

Listening to music synchronized with exercise elevates mood, increases endurance, reduces perceived effort and increases metabolic efficiency, according to University of South Queensland’s Peter C. Terry, who collaborated with Karageorghis to produce a comprehensive review of psychophysical effects of music in sport and exercise.

Karageorghis collaborated with Brunel colleagues Denis A. Mouzourides, Tariq A. Sasso, Daley J. Morrish, and Carolyn L. Walley with David-Lee Priest of University of East Anglia,  to conclude that “
motivational qualities of music have considerable bearing on how long participants might endure a repetitive activity and their feelings during the task.”

David-Lee Priest

David-Lee Priest

They pointed to the public health and social implications of their findings when they asserted that “motivational synchronous music may serve as an important tool to underpin current initiatives of Western governments to improve public health and lessen the financial burdens on public health services.”

Still Fulfilling Your New Year’s Resolutions?

-*Did New Year’s Resolutions fade as quickly as the month of January?

Katherine Milkman

Katherine Milkman

If so, University of Pennsylvania Katherine Milkman has a recommendation to resume the good intentions toward goals: “Nudges”—small environmental interventions that can shift behavior to increase adherence to challenging commitments, whether at work or in personal life.

Hengchen Dai

Hengchen Dai

Milkman collaborated with Wharton colleague Hengchen Dai and Harvard’s Jason Riis to investigate “temporal turning points” – moments that feel like a new beginning, like New Year’s Day or beginning a new job or school.

Jason Riis

Jason Riis

Milkman, Riis, and Dai reported several examples of the “fresh start effect”:  They found that the number of online Google searches for the term “diet” increase following temporal landmarks like the beginning of a new week, month, year, or semester; a birthday or a holiday.
The largest increase—82% above the baseline—occurred immediately after New Year’s Day for nine years they studied.

Similarly, the number of gym visits of 12,000 undergraduates over 18 months increased in January, then declined, with smaller increases at the beginning of each week, each month, and each term.

 This pattern also occurred among 43,000 participants in a goal-setting website, stickK, over 30 months.

Members can set goals and contractually agree to consequences for failing to attain them, such as community sanctions to monetary payments to disliked organizations.
The greatest number of contracts—145% above the average rate—were signed at the beginning of the New Year, and more contracts were signed at the beginning of each week.

Richard Thaler

Richard Thaler

Commitments to pursue and return to goals increase after these “notational boundary,” described by Richard Thaler of University of Chicago.
A temporally-triggered “fresh start” can compensate for limited willpower and persistence by giving people a chance to restart their commitments.

Besides “temporal turning points,” self-designed “nudges” can be contingency plans for a specific corrective action when confronted with the temptation to deviate from the goal path: “Whenever situation x arises, I will initiate the goal-directed response y.”

Peter Gollwitzer

Peter Gollwitzer

New York University’s Peter Gollwitzer calls these mitigation plans “implementation intentions,” which result in better adherence to goal-directed efforts when developed before tempting situational cues.

Stephen Ciccone

Stephen Ciccone

The stock market’s “January Effect” of better-than-average performance early in the year may result from the “fresh start” phenomenon, although Stephen J. Ciccone of University of New Hampshire argues that it may be more affected by investor optimism and the “false hope syndrome.”

Janet Polivy

Janet Polivy

University of Toronto’s Janet Polivy and C. Peter Herman describe the “false hope syndrome’s” unrealistic expectations about the likely speed, amount, ease, and consequences of self-change attempts, and subsequent disappointment of these optimistic aspirations.

Ciccone found that investor sentiment, as measured by the University of Michigan’s Index of Consumer Confidence, peaks in January and suggested that optimistic bid up stock prices of firms with higher levels of uncertainty.

C. Peter Herman

C. Peter Herman

Typically, these firms are unable to meet the optimistic expectations, and disappoint investors when they under-perform.
However, this pattern continues each year, probably due to the combined impact of  “fresh start effect” and the “false hope syndrome.”

Unrealistic optimism has been well-documented in overestimates of personal abilities, future performance and the impact of achieving goals, as well as underestimates of the time and effort to achieve goals.

Jeffrey Jensen Arnett

Jeffrey Jensen Arnett

Jeffrey Jensen Arnett of Clark University found that both 200 adolescents and more than 200 adults held optimistic biases regarding the risks of smoking even though the strong majorities of smokers and nonsmokers in these groups agreed that smoking is addictive and causes death for “most people” who smoke.

However, the adolescent and adult smokers doubted that they would die from smoking even if they smoked for 30 or 40 years, and most adolescents believed that they “could smoke for a few years and then quit.”

Roger Buehler

Likewis Roger Buehler

Likewise, most people underestimate time required to complete tasks, called “planning fallacy”  by Wilfred Laurier University’s Roger Buehler, Dale Griffin of University British Columbia and University of Waterloo’s Michael Ross.

Dale Griffin

Dale Griffin

They found that 465 volunteers:

  • Underestimated their own but not others’ completion times for academic and nonacademic tasks
  • Focused on future plans rather than comparing with similar past experiences when making completions time estimates
  • Attributed their past errors in predicting completion times to external, transient, and specific factors, implying less personal accountability for misjudgments.
Mike Ross

Mike Ross

Volunteers were able to eliminate their bias toward inaccurately optimistic estimates when they explicitly considered connect relevant past experiences to inform current estimates.

Fiona Jones

Fiona Jones

The optimism bias can be reduced by setting modest, attainable goals, according to University of Leeds’ Fiona Jones and Adrian Coggins with Peter Harris of University of Sussex and University of Hertfordshire’s Hilary Waller.

They compared 119 volunteers’ expectations about their participation in a twelve-week-long exercise course and their actual attendance, and found that participants who set smaller goals were more likely to achieve and maintain the goal behavior over time.

Loneliness, Happiness Affect Gene Expression, Health

Loneliness not only feels bad, but it’s also bad for your health.

Steve Cole

Steve Cole

Subjective social isolation is a known social epidemiological risk factor that has been linked to heart disease, viral infections and cancer.

In addition, loneliness has physical effects on gene regulation and expression, according to DNA microarray analyses of 209 gene transcripts (the first step in synthesizing a protein) out of more than 20,000 in white blood cells of 14 volunteers.

Louise Hawkley

Louise Hawkley

UCLA’s Steve Cole, Jesusa Arevalo, and Caroline Sung collaborated with Robert Rosen of University of Texas and University of Chicago’s Louise Hawkley and John Cacioppo to report that individuals who reported high loneliness on Daniel Russell’s UCLA Loneliness Scale showed different gene expression in circulating leukocytes than volunteers who did not report loneliness.

Daniel Russell

Daniel Russell

Lonely individuals were less able to ward off inflammatory responses and viruses, and less able to produce antibodies because controlling genes were under-expressed.
In contrast, lonely individuals were at risk for greater inflammatory responses and more active immune systems  because the related genes were over-expressed.

These volunteers showed “down-regulation” of genes supporting mature B lymphocyte function and type I interferon response, when researchers controlled for effects of circulating cortisol levels, demographic, psychological, health risk, medications, or social network factors.

The social experience of loneliness desensitizes glucocorticoid receptors and reduces cortisol’s immune control and anti-inflammatory effects.

Cole’s team found that loneliness was more dependent on the number of close relationships rather than the total number of acquaintances.
This suggests the importance of cultivating meaningful social relationships for both social support, reciprocity, and for enhanced health.

Barbara Fredrickson

Barbara Fredrickson

Cole, and Arevalo collaborated with UCLA colleague Jeffrey Ma and University of North Carolina’s Barbara Fredrickson, Karen Grewen, Kimberly Coffey, Sara Algo, and Ann Firestine to consider the impact of different types of happiness on gene expression in 80 adult volunteers.

They evaluated two types of happiness:

  • Eudaimonic well-being,“ a Socratic ideal based on leading a virtuous life, striving toward a meaningful purpose, pursuing “worthwhile” service, and more fully developing personal capabilities
  • Hedonic well-being,” focused on pleasure, consumption, and enjoyment.
Karen Grewen

Karen Grewen

Fredrickson’s team compared leukocyte basal gene expression profiles for volunteers who reported hedonic well-being in contrast to those who reported eudaimonic well-being.
The team also considered negative psychological and behavioral factors.

People with high levels of hedonic well-being showed “up-regulated” pro-inflammatory genes and decreased expression of genes involved in antibody synthesis and type I IFN response in peripheral blood mononuclear cells during stress [conserved transcriptional response to adversity (CTRA)].

Kimberly Coffey

Kimberly Coffey

In contrast, volunteers with high levels of eudaimonic well-being showed CTRA down-regulation, suggesting less stress on body systems.

Fredrickson and team concluded that “genes can tell the difference” between a purposeful life and a more pleasure-centric life, even when self-reports do not distinguish between these two types of happiness.

Ann Firestine

Ann Firestine

These finding suggest the importance of pursuing prosocial purposes and developing meaningful, trust-based relationships with others to experience greatest health and happiness – down to your genes.

Explicit Gratitude Increases Well-Being, Reduces Materialism

Robert Emmons

Robert Emmons

Gratitude, or appreciating a beneficial outcome, has significant benefits to physical and emotional health, according to Robert Emmons at the University of California.

He found that volunteers who kept a gratitude journal exercised more frequently, reported fewer physical symptoms of pain, were more optimistic about the upcoming week, and showed greater progress towards personal goals over a two-month period than people who kept journals that reported events factually or allowed them to complain.

Jeffrey Froh

Jeffrey Froh

Emmons worked with Hofstra’s Jeffrey J. Froh and Giacomo Bono of California State University, Dominguez Hills to consider gratitude in contrast to happiness among 700 middle school students, who completed measures of gratitude, prosocial behavior, life satisfaction, and social integration, with re-measures after 3 months and 6 months.

Giacomo Bono

Giacomo Bono

Emmons and team found that students who expressed gratitude initially showed greater social integration after 6 months, and these dimensions enhanced each other.
Theyposit that gratitude may help young people develop greater emotional and social well-being, and prosocial contribution to their communities.

Jennifer Wilson

Jennifer Wilson

This team was joined by Hofstra’s Jennifer Wilson and Noel Card of University of Arizona in another study of young adults who practicing daily gratitude exercises.

These volunteers reported higher levels of alertness, enthusiasm, determination, attentiveness and energy compared to people who focused on social comparisons with people in better or worse life situations than they.

Noel Card

Measuring and Increasing Hope to Improve Performance, Health

Hope shifts focus from the present moment to action paths (“pathways”) required to achieve future goals and motivation to follow these goal routes (“agency”).

Some advocates of mindful attention to the present moment question cultivating hope because it focuses on the future instead of the present, despite abundant empirical evidence that hope is positively associated with academic achievement, health outcomes, and more.

Benjamn Franklin

Benjamn Franklin

Buddhist thinkers argued that hope is illusory and prolongs human suffering and even America’s sage, Benjamin Franklin, noted that one who lives on hope will die fasting.

C. RIck Snyder

C. RIck Snyder

In contrast, hope investigator University of Kansas’s Charles “Rick” Snyder substantiated the health and performance benefits of hope and distinguished hope from learned optimism, self-efficacy, and self-esteem.

He developed and validated measures of hope as a trait and as a state, evaluating “pathways” and “agency” beliefs, with collaborators Cheri Harris, John R Anderson, Sharon A. Holleran, Lori M Irving, Sandra T. Sigmon, Lauren Yoshinobu, June Gibb, Charyle Langelle, and Pat Harney.

Snyder and team reported that children and adults across ethnic and gender groups who scored higher in hope demonstrated:

He offered tips for setting goals and enhancing “pathways” and “agency” toward goals, including:

  • Prioritizing self-selected goals
  • Developing multiple paths for each goal
  • Expecting positive outcomes while designing ways to remove potential obstacles.
Pam Omidyar

Pam Omidyar

One practical application of Snyder’s Hope Theory is Re-Mission,video game for cancer patients, developed by HopeLab’s Pam Omidyar, Pam Kato, and UCLA’s Steven Cole.

Pam Kato

Pam Kato

Adolescent patients in remission with acute leukemia, lymphoma, and soft-tissue sarcoma are required to continue daily chemotherapy treatments for up to several years.
Those who miss even 20% of their daily treatments increase their mortality risk by 200%.

Steve Cole

Steve Cole

Kato collaborated with Cole, West Virginia University’s Andrew Bradlyn and Brad Pollock of University of Texas to evaluate video-game interventions to improve young people’s medication adherence.

 They conducted a randomized trial with baseline and 1 month and 3 month assessments at 34 medical centers in the United States, Canada, and Australia.

Brad Pollock

Brad Pollock

Volunteers were 375 males and females between 13 to 29 years old undergoing chemotherapy for at least 4 months.
Participants in the video game tailored to young cancer patient increased adherence to chemotherapy by 50%, and showed increased self-efficacy and knowledge, compared with those who played commercial video games or no video games.

fMRI studies showed that their brains were most active when they played the game instead of observing the game interface.
Most active areas were:

  • Limbic structures including caudate, putamen, and nucleus accumbens, measuring anticipatory excitement before securing a reward
  • Thalamus, “the internet of the brain”
  • Hippocampus, the link between experience and long-term memory

Cole further evaluated Re-Mission and Zamzee, a motivational system to promote physical activity among young people, and now leads HopeLab’s Re-Mission 2 to further amplify positive health behavior and resilience.

Improving Visual Information Processing for Better Performance – Boston Subway Map and More

Transit maps are one example of graphic displays that require the viewer to rapidly process visual information to make quick decisions in often crowded and noisy conditions.

MBTA Map 2013

MBTA Map 2013

Cognitive scientists have studied this type of challenging task load in human performance, but seem not to have been consulted when Boston’s Massachusetts Bay Transportation Authority (MBTA) sponsored a contest to redesign the system map in Spring 2013.

Michael Kvrivishvili

Michael Kvrivishvili

Michael Kvrivishvili, a graphic designer at Moscow’s Art Lebedev Studio, submitted the winning design, which was judged by aesthics and presumed usability.

MIT’s Ruth Rosenholtz, Lavanya Sharan, and Shaiyan Keshvari empirically scrutinized Kvrivishivili’s design using computational modeling to analyze the design’s potential visual clutter and its impact on peripheral vision.

Ruth Rosenholtz

Ruth Rosenholtz

Team Rosenholtz’s model generated “mongrels,” or  alternate representations of Kvrivishvili’s redesigned subway map, that abbreviate and abstract visual elements like color, text, space, line orientation before processing in the visual cortex.

Lavanya Sharan

Mongrels can account for peripheral vision’s generalized synthesis of information outside direct line-of-sight, which provides an overall impression while sacrificing details to speed information processing.

DesignEye tool enables A/B comparisons between designs and judgments about the quality of a design through simple design visualization.

Design optimization seeks to remedy effects of visual clutter, or excessive and disorganized items that can cause:

  • Crowding
  • Masking
  • Reduced recognition due to occlusion
  • Decreased ability to segment scenes
  • Poorer visual search performance.

 Rosenholtz’s group investigated reliable measures of visual clutter to help designers optimize displays for more effective information processing.

Saudi Women’s Driving Campaign meets “When Everything Changed”

Saudi Women Driving CampaignSaudi Women’s Driving Campaign occurred near the time that New York Times columnist Gail Collins discussed her book When Everything Changed: The Amazing Journey of American Women from 1960 to the Present  at Harvard’s Radcliffe Institute for Advanced Studies.
Though separated by oceans and time zones, both events refer to the continuing challenge of women achieving parity in societies and workplaces.

Sheikh Saleh bin Saad al-Luhaidan

Sheikh Saleh bin Saad al-Luhaidan

Although there is no law mandating that women do not drive cars in Saudi Arabia, it is actively discouraged by religious leaders like Sheikh Saleh bin Saad al-Luhaydan, who asserted that driving injures women’s pelvis and ovaries and causes birth defects in children of women.

Saudi Woman DrivingSaudi Police detained women who drove cars on 26 October 2013, Saudi Women’s Driving Day, until their “guardians” arrived.
At that time, women were instructed to sign an affidavit stating that they would not drive a car in the future.

Jennifer Psaki

U.S. State Department spokesperson Jennifer Psaki said, “We support the full inclusion of women in Saudi society…. we would support their ability to drive.  We support, of course, the right of women everywhere to make their own decisions about their lives and their futures and the right to benefit equally from public services and protection from discrimination.”

According to Collins, “everything changed” for women in the U.S. in the 1960s, although many might say that many issues toward equity remain unresolved.
So far, everything has not changed for Saudi women, but they may find encouragement and even humor in Collins’ chronicle of women’s experience toward parity in the U.S.

Word of Mouth, Social Media Expand Silicon Valley Networking with a Purpose

Networking with a Purpose

A professional development collaboration among Cisco, Citrix, eBay, EMC, Ericsson, Intel, Oracle, and other Silicon Valley technology companies using the IEEE model of “Birds of A Feather” discussion topics was introduced in a previous blog post.

IEEE

Anna Van Rijswijk, formerly of Cisco, developed this program based on survey data indicating that unstructured professional networking can feel awkward, stressful, and uncomfortable to many potential and actual participants.

Anna Van Rijswijk

Anna Van Rijswijk

Networking with a Purpose format provides structure and focus found in Speed Networking, Tom Jaffee’s business-focused adaptation of Rabbi Yaacov Deyo’s Speed Dating to enable members of his congregation to meet potential life partners. Yaacov Deyo

A Columbia alumnus, Jaffee noted that “at business functions, people often find themselves spending too much time with a small group rather than establishing multiple contacts throughout the function.”

Tom Jaffee

Tom Jaffee

To provide a solution, he built a company that offers events to increase chances that participants will make valuable business connections, much like the no-cost, self-organizing alternative, Networking with a Purpose.

Word of Mouth Marketing (WOMM) and social media mentions on Networking with a Purpose LinkedIn Group, Twitter (#SVBOF), and Facebook dramatically increased demand for registration at Silicon Valley Networking with a Purpose in-person events, and no-cost tickets typically “sell out” within minutes of posting the event invitation. WOMMA

The fifth Networking with a Purpose event is scheduled for Wednesday 20 November 2013 at eBay in San Jose, California, with popular discussion topics including:

  • Enhancing Personal Brand
  • Communicating Upward
  • Career Planning and Accountability
  • Design Thinking
  • Sketchnoting and Graphic Facilitation
  • Think Big, Play Big
  • Work Life Integration
  • Salary Negotiation
  • Office Feng Shui
  • iPhoneography

Silicon AlleyOrganizers have received strong post-event ratings from participants and have been contacted by colleagues in Silicon Alley – New York City – who wish to replicate this approach to professional networking.

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.

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.

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

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 – Music – Part 4 of 5

Many people intuitively turn to music when they want to regulate energy and mood.

Valorie Salimpoor

Valorie Salimpoor

Listening to music evokes sympathetic nervous system activity, a sign of emotional arousal measured by changes in heart rate, respiration, electrodermal activity, body temperature, and blood volume pulse, according to Rotman Research Institute’s Valorie Salimpoor, McGill’s Mitchel Benovoy, Gregory Longo, Jeremy Cooperstock, and Robert Zatorre.

Mitchel Benovoy

Mitchel Benovoy

The researchers asked twenty-six participants to select and listen to “pleasurable” music and researchers selected “neutral” music for participants based.
Pleasure ratings and emotional arousal measures were strongly related, and those who did not experience pleasure also showed no significant increases in emotional arousal.

Gregory Longo

Gregory Longo

This finding suggests that listening to preferred music can be used as a mood-enhancement and stress management approach.

Lori Gooding

Lori Gooding

Kentucky University’s Lori Gooding and Olivia Yinger validated music’s stress management benefits for surgical patients.
They found that listening to music can reduce anxiety, subjective pain, and requests sedative medication following surgery.

Olivia Yinger

Olivia Yinger

Slow music expedited relaxation and reduced pain, suggesting that music tempo, rhythm and volume can contribute to reduced anxiety, improved treatment experiences, with lower medical costs in medical intensive care units.

Nick Perham

Nick Perham

Besides managing stress, listening to background music before task performance can increase attention and memory by evoking arousal and positive mood, according to Nick Perham and Joanne Vizard, then of University of Wales Institute Cardiff.

Joann Vizard

Joann Vizard

However, listening to music during a task decreased serial recall among adult volunteers, again pointing to the value of listening to music before but not during tasks that require acute concentration.

Kristie Young

Kristie Young

Beyond passively listening to music, performing music by singing during a complex task can decrease performance.
Monash University’s Genevieve Hughes and Kristie Young with Christina Rudin-Brown of Transport Canada found that singing while performing complex, attention-requiring task increases mental workload and distraction.

Christina Rudin-Brown

Christina Rudin-Brown

They asked participants to learn the lyrics two popular songs, then sing them while operating a simulated car during a 6.6 km urban trip with four speed zones and encountering expected and unexpected traffic events.

Volunteers who sang while “driving” scanned their visual field less often, focused on the area directly ahead (“cognitive tunnelling”), and were less aware of potential hazards during a peripheral detection task (PDT).
However, singing reduced “driving” speed and enabled volunteers to maintain position in their “lanes.”

Efforts to compensate for the increased mental workload associated with singing and listening to music appeared ineffective, suggesting that listening to music during complex tasks impairs performance.

Jim Blascovich

Jim Blascovich

In contrast to performance-disrupting impact  of listening to music while performing complex tasks, SUNY Buffalo’s Karen Allen with Jim Blascovich of University of California, Santa Barbara reported that surgeons worked more quickly and accurately when they listened to preferred music, and physical stress was reduced, indicated by cardiac and electrodermal autonomic responses, hemodynamic measures.
Those who listened to no music did not perform as quickly and accurately as those who listened to their preferred music.

Stress-reducing and performance impacts of music appear related to both personal musical preferences, and musical temp and genre.

Leigh Riby

Leigh Riby

Northumbria University’s Leigh Riby found that “uplifting” music can boost mental alertness, attention and memory.

Volunteers pressed a keyboard space bar when a green square appeared on screen but not when they saw different-colored circles and squares under two conditions: in silence and while listening “uplifting” concertos (Vivaldi’s Four Seasons).

Riby measured brain activity with an EEG and found that participants responded accurately more quickly when listening to the ”uplifting” Spring concerto in contrast to performing with no music or the slower, more somber Autumn concerto.
The Spring concert “seemed to give rise to particular imagery in the brain and evoke positive, contented feelings which translated into higher levels of cognitive functioning,” according to Riby.

The underlying mechanism of music’s effects on attention, concentration, and performance is dopamine release in response to music that elicited “chills” or ‘‘musical frisson” — changes in skin conductance, heart rate, breathing, and temperature that were correlated with pleasurability ratings of the music.

Salimpoor and her McGill team, including Kevin Larcher and Alain Dagher, used PET and fMRI brain imaging techniques to measure anticipation and consumption of music as a reward, and demonstrated that volunteers who listen to preferred, “pleasurable” music experience greater release of dopamine, which is associated with emotional arousal and pleasurability ratings.

This is one of the first demonstrations that an abstract, cognitive, non-tangible reward can lead to dopamine release, and that different brain circuits are involved in anticipating (caudate) and experiencing (nucleus accumbens) musical tension and resolution.

University of Miami’s Teresa Lesiuk reported improved task speed, performance, and new ideas with information technology specialists who listened to preferred music.

She attributed these positive effects to reduced stress and improved mood, and found that people who were moderately skilled at their jobs benefited most, but experts experience no benefit.
Consistent with findings that music can be a distraction in cognitively-demanding tasks, novices found that music undermined performance.

When people’s minds wander, music can help focus on the present moment, according to Amit Sood of Mayo Clinic, who advocates music’s value in developing and reinforcing Mindful Attention – another approach to managing stress.
