¿Las personas inteligentes oyen rock y heavy metal?

 
Todos hemos visto alguna vez a un ‘melenudo' embutido en unos pantalones elásticos, llevando una camiseta de Metallica y escuchando música en su mp3. Le observamos mientras menea su cabeza suavemente, suponemos que al ritmo de alguna canción de Iron Maiden, Black Sabbath o alguna otra banda de heavy metal. Sin darnos cuenta, nos vienen a la mente todos esos estudios clásicos que dicen que las personas que escuchan este tipo de música tienen más tendencia a ser agresivos, o que incluso tienen un mayor riesgo de suicidarse.

Y sin embargo, más allá de los estereotipos, podríamos estar frente a un superdotado que intenta deshacerse de todas las tensiones y relajarse. Al menos así lo cuenta un estudio de la Universidad de Warwick. Tras preguntar a más de mil estudiantes con altas capacidades intelectuales, encontraron que el rock era el estilo musical preferido por estos chavales de entre 11 y 18 años. Aquellos estudiantes comentaron que utilizaban el heavy metal para alcanzar una catarsis, como una forma de superar sus emociones negativas y afrontar la presión académica a la que estaban sometidos.

¿Escuchar heavy metal es propio de personas inteligentes?

Un trabajo presentado en la 18th Annual Conference of the Association for Psychological Science en Nueva York, mostraba que las personas que preferían la música alternativa, el rock y el heavy metal obtuvieron puntuaciones más altas en una medida objetiva de inteligencia. Eran particularmente mejores en la capacidad de abstracción. Los autores del trabajo plantearon la posibilidad de que esto se debiera a la mayor frecuencia de metáforas y lenguaje abstracto que existe en las canciones propias de este estilo, al que están expuestos de forma recurrente los fans. 

¿Cómo son los ‘rockeros' y los ‘metal heads'? El rock, la música alternativa y el heavy metal fueron definidos en otra investigación como música ‘intensa y rebelde'. Según este estudio, preferir este tipo de música se asocia con frecuencia a ciertos rasgos de personalidad como estar abierto a experiencias nuevas, disfrutar con el riesgo y ser físicamente activo. Sin embargo, no encontraron relación con el neuroticismo, como sería esperable según los estereotipos que asocian este estilo musical con las emociones negativas.

En definitiva, lo que está claro es que las apariencias engañan.

Una música para cada actividad


Daniel J. Levitin, exproductor musical de grandes figuras como Stevie Wonder o Carlos Santana, neurocientífico y actual director del Laboratory for Music Perception, Cognition and Expertise de la Universidad McGill, en Montreal (Canadá), confeccionó no hace mucho una exhaustiva lista de recomendaciones sobre qué género musical es más apropiado para realizar cada actividad cotidiana. Así, asegura que mientras leemos o estudiamos asignaturas como Historia o Literatura, la música clásica, el jazz, el blues y el tecno favorecen la concentración.

Si lo que queremos es aumentar el rendimiento mientras hacemos ejercicio, una buena opción sería oír I Feel Good de James Brown, con 146 bpm (pulsos por minuto), casi el mismo ritmo que el single de Madonna titulado Hung up, también recomendado por Levitin. Antes de ir a dormir conviene bajar a 60-70 bpm, con piezas como la Canción de cuna de Brahms. La música de Beethoven, sin embargo, no es una buena opción cuando pretendemos relajarnos.


¿La música que escuchamos dice mucho de nuestra personalidad?


Los psicólogos Peter J. Rentfrow y Samuel D. Gosling, de la Universidad de Texas han demostrado científicamente que las preferencias musicales de cada individuo definen su personalidad. Hace unos años idearon el “Test Corto de las Preferencias Musicales” (STOMP, por sus siglas inglesas) y sometieron a varios centenares de jóvenes a sus preguntas.

Según se deduce de sus resultados, publicados en la revista Journal of Personality and Social Psychology, si usted es amante del blues o del jazz probablemente será una persona lista, imaginativa, tolerante y liberal, además de abierta a nuevas experiencias. Los consumidores de heavy metal coinciden en su elevada inteligencia, pero son además especialmente curiosos, atléticos y habituales “cabecillas” sociales. Extroversión, locuacidad, energía y una elevada autoestima son los rasgos que predominan entre los fans del hip-hop y el funky. Y quienes escuchan las canciones de la popular Madonna, o la banda sonora de Bailando con Lobos, suelen ser sujetos conservadores, adinerados, felices, agradables y, con frecuencia, emocionalmente inestables.


How to Prevent Burnout from Stress: Live like a Sprinter, not a Long Distance Runner

When we expend energy, we draw down our reservoir. When we recover energy, we fill it back up. Too much energy expenditure without sufficient recovery eventually leads to burnout and breakdown (Overuse it and lose it). Too much recovery without sufficient stress leads to atrophy and weakness (Use it or lose it).
-Jim Loehr and Tony Schwartz, The Power of Full Engagement
How to Prevent Burnout from Stress: Live like a Sprinter, not a Long Distance Runner
There needs to be an equal balance between stress and recovery- too much of either one has negative consequences
 
Nature is constantly oscillating- think of tides moving in and out, the seasons changing, or the sun rising and setting. We as human beings naturally follow a similar rhythm with our energy levels. Our natural state is to oscillate between rest and activity, similar to a sprinter. Unfortunately, our society of technological innovation socially sanctions living like a long distance runner- we ignore rest and fail to recognize its necessity for preventing burnout and sustaining high performance.
 
Ignoring recovery for too long causes burnout- symptoms of being burned out include emotional exhaustion, loss of motivation, detachment, isolation, and irritability.

Are your addicted to living like a long distance runner?

Living in a state of stress produces an adrenaline rush, and over time, this becomes addictive, and we lose the ability to relax. Common sense would tell us we need to take breaks and rest, but instead we overindulge in work, and face the consequences. Researchers have found that self-described workaholics have a significantly higher than average incidence of stress-related illnesses, divorce, and alcohol abuse.

Are you creating artificial relaxation and alertness?

If you regularly rely on alcohol, marijuana or sleeping pills to calm down, you may be trying to create relaxation (artificially). Similarly, if you rely on stimulants such as caffeine or amphetamines, you are trying to create alertness (artificially). Both of these artificial means of oscillation are masking the bigger problem- you are still living life like a long distance runner.

Are you creating artificial importance?

Do you like the feeling of importance when you become busier? Even when it means being unavailable to your friends and family? This artificial importance will only create artificial success, as you are still living life like a long distance runner.

Are your work habits putting you at risk to karoshi?

Karoshi is the term in Japan which means “death from overwork”. This is apparently a fairly common occurrence. In fact, I just read about a Toyota engineer who worked himself to death today (he died of heart disease). Additionally, I have known several people in the workforce who have had heart attacks after working extreme long hours under high pressure.

Research shows that these five key factors contribute to karoshi:
  • Extreme long hours that interferes with normal rest patterns
  • Night work that interferes with normal rest patterns
  • Working without holidays or breaks
  • High pressure work without breaks
  • Extremely demanding physical labor and continuously stressful work
Here are some tips for preventing burnout (or karoshi!), and living like a sprinter:

Tips for Preventing Burnout from Stress and Living like a Sprinter

1) Balance stress and recovery to achieve your best performance

Push yourself beyond your ordinary limits, and regularly seek recovery, and you will grow. This is similar to lifting weights at the gym. The problem with people who live like long distance runners is that they don’t allow themselves to recover, and get burned out as a consequence. This brings us to the topic of tip 2.

2) Create a ritual of disconnecting

New technologies such as Blackberries/PDA’s, and social networking tools (ex. Facebook, Twitter), make it easy for us to never truly disconnect. Several people I work with will bring their work phones/laptops with them on vacation, and check e-mail/take phone calls the entire time. This is faulty, socially-sanctioned “live life as a long distance runner” logic.
It is a very good plan every now and then to go away and have a little relaxation… When you come back to the work your judgement will be surer, since to remain constantly at work will cause you to lose the power of judgement.
-Leonardo Da Vinci
Da Vinci’s advice still applies to us today. To prevent work burnout, create a daily ritual (read my post on creating consistent daily habits) of completely disconnecting- have a daily stopping point. For example, if you are a business traveler, make a habit of not working during your commute, and instead, relax and read books/magazines. If you are on vacation, completely disconnect from your work- don’t bring your PDA or laptop.

Another option for preventing work burnout is to disconnect during your lunch. A lot of people fall into the habit of eating at their desk, or eating with coworkers and discussing work-related topics. To truly disconnect and use your lunch break to recover, you may need to eat by yourself.

3) Create healthy breathing, eating, sleeping, and exercising habits

Breathing: This is an easy way to relax and prevent burnout- throughout your day, make a habit of breathing in to a count of three and out to a count of six, for several minutes. This will help you relax deeply.

Eating: Eat small meals at regular intervals (five to six times a day is recommended), in amounts that are satisfying (not over or under filling). Try to eat primarily foods that are low on the glycemic index, as these will provide a steadier source of energy. And don’t forget to drink plenty of water!

Sleeping: Get 7-8 hours of sleep. If you are able to, take at catnap in the afternoon. Winston Churchill was a proponent of this, explaining that a catnap helps you get two days in one, as you wake up more alert and sustaining energy.
 
Exercising: Work out 3-5 times per week, and add some form of strength training to your routine (read my post on losing weight by gaining muscle). Strength training is just as important as cardiovascular training, especially as we age- on average, we lose one-half pound of muscle mass each year after the age of forty in absence of exercise.

People who exercise on work days are happier, suffer less stress and are more productive


People who exercise on work days are more productive, happier and suffer less stress than on non-gym days, scientists revealed today.

University of Bristol researchers found that employees who enjoyed a workout before going to work - or exercised during lunchbreaks - were better equipped to handle whatever the day threw at them.

It also found that people's general mood improved on days of exercise but they became less calm on non-exercise days.

The research, published in the International Journal of Workplace Health Management, is the first of it's kind to prove that exercise during work hours has mental, as well as physical benefits.

Jo Coulson, Research Associate in the University's Department of Exercise, Nutrition and Health Sciences, said: 'Our statistical results were very important.

'On exercise days, people's mood significantly improved after exercising. Mood stayed about the same on days they didn't, with the exception of people's sense of calm which deteriorated.

'Critically, workers performed significantly better on exercise days and across all three areas we measured, known as mental-interpersonal, output and time demands.'

The study group was made up of 200 university staff and employees working for a pensions company and an IT firm.

Each employee completed a questionnaire about their mood, workload and performance on days when they exercised.

The data was compared to answers from days participants opted not to exercise.

The workers, who were already in the habit of exercising, chose their own mode, frequency and intensity of workout to better reflect a real-life situation.

Most used a gym and did classes while some did weight training and team sports.

The key findings were: 

Seventy two per cent reported improvements in time management on exercise days compared to non-exercise days.

Seventy nince per cent said mental and interpersonal performance was better on days they exercised.

Seventy four per cent said they managed their workload better.

The questionnaire scores were 27 per cent higher on exercise days in categories such as dealing calmly with stress and 41 per cent higher for feeling motivated to work.

Those who exercised were also 21 per cent higher for concentration on work, 25 per cent for working without unscheduled breaks and 22 per cent higher for finishing work on time.

Feedback from focus groups found that people who built exercise into their workday were re-energised, calmer and more able to solve problems.

Ms Coulson added: 'It's generally well-known now that there are many physical and mental health benefits that can be gained from regular exercise.

'If people try to fit an active break into their working day, they might also experience the added bonus of their whole day feeling much more productive.

'And that always feels good in our busy lives.

'The study also begs the question whether employers can afford not to be encouraging active breaks.

'The suggestion is that employers who are ahead of the game in offering proper on-site facilities actually get less from their employees on days that they don't exercise.'
