Managing Workplace Interruptions

Edward Sykes

Most office workers spend an average of two hours a day doing unplanned tasks, according to Sheridan Institute’s Edward Sykes.
These work interruptions are associated with:

Unplanned tasks decrease productivity and are characterized by:

  • Intrusions – Unplanned interactions initiated by others: Synchronous communication including instant message, phone call, or a coworkers visiting to talk,
  • Distractions – Unplanned focus change from a task to environmental conditions like other conversations,
  • Breaks – Unscheduled task stoppage to rest, visit the restroom, have a meal,
  • Discrepancy Detection – Unplanned task stoppage to correct errors or redirect work effort toward a revised objective.

Unplanned workplace interruptions are increasingly prevalent due to rising incidence of:

  • Open and collaborative workspaces,
  • Technological interruptions,
  • Meetings.

Open space floor plans increase unplanned interruptions, perceived stress, and “cognitive fatigue,” due to greater noise levels and reduced privacy for employees.
These factors also reduce employees’ job satisfaction, found Carnegie Mellon’s Sheldon Cohen and E. M. De Croon and team of University of Amsterdam.

Synchronous communications are more disruptive than asynchronous communications, which allow response at a convenient time and mitigate the negative impact of task-shifting on cognitive load and stress level, noted University of Texas’s Julie Rennecker and Lindsey Godwin, now of Champlain College.

Strategies to mitigate the impact of work disruptions include time management and boundary setting, according to Tulane’s Greg Oldham, Carol Kulik of University of South Australia and Florida State University’s Lee Stepina.
 They suggested that employees:

-“Batch” communication to check email and returning phone calls at specified intervals,

-Block technology pop-ups, alerts, sounds to avoid startling interruptions,

James Tyler

-Organize tasks around energy peaks, with tasks requiring the most effort and concentration earlier in the workday and after a break, also advocated by Purdue’s James Tyler and Kathleen Burns of University of Wisconsin,

-Take active breaks, such as walking outside to breathe outdoor air,

-Schedule interruption-free intervals, to increase perceived control over interruptions and reduce stress, also cited by Duke’s Andrew Carton and John Aiello of Rutgers,

-Create “work-arounds” for open space floor plans by:
.Installing higher cubicle dividers,
.Providing noise-cancelling headphones,
.Offering white noise machines to reduce ambient notice,
.Designating reservable private work rooms for audio privacy,

-Reduce meeting frequency to focus on issues that require group discussion, consensus, commitment.

A counterpoint argument is that task interruptions provide benefits, proposed by Rutgers’s Quintus Jett, and Jennifer George of Rice University.
The argued that unplanned and planned interruptions :

    Prevent widespread rework when employees alert colleagues to a work discrepancy or error,

  • Increase productivity during repetitive or well-learned tasks that may lead to boredom, errors, or lost task focus.

Brief Aerobic Exercise Increases Attention, Reading Performance

Michele Tine

As little as 12 minutes of aerobic exercise increased selective attention and reading comprehension scores for low-income young adults at a highly selective, ”academically elite” (“Ivy League”) US undergraduate university, reported Dartmouth College’s Michele T. Tine and Allison G. Butler of Bryant University.

Even these highly-skilled participants, admitted to one of the US’s top academic institutions, had significantly different scores on Selective Visual Attention (SVA) and reading comprehension pre-test tasks, depending on their socio-economic status.

Selective Visual Attention (SVA) is the ability to focus on visual targets while ignoring irrelevant stimuli, and an Executive Function” (EF) required for academic and on-the-job learning, according to University of Oregon’s Courtney Stevens and Daphne Bavelier of University of Rochester.

Specifically, selective attention predicts skills in:

according to University of Oregon’s Stevens with Brittni Lauinger and Helen Neville.

Executive Functions, like Selective Visual Attention (SVA,) are positively correlated to socioeconomic status, found University of Pennsylvannia’s Daniel A Hackman and Martha J Farah, indicating that people with financial advantages often perform better on Executive Function tasks than people from disadvantaged backgrounds.

One well-validated measure of Selective Visual Attention (SVA) is the d2 Test of Attention, rapid trials of a manual letter cancellation task, developed by Rolf Brickenkamp and Eric Zillmer of Drexel University.
Participants Tine and Butler’s investigation indicated when they observed the target character among visual distractors.

One intervention to increase Executive Function skills, including Selective Visual Attention (SVA) is aerobic exercise, according to University of British Columbia’s John Best.

In addition to increasing Executive Functions, aerobic exercise increases levels of cortisol and brain-derived neurotrophic factor (BDNF).
These elements are associated with cognitive performance including Selective Visual Attention (SVA), reported Texas Tech’s Lee T Ferris and Chwan-Li Shen with James S Williams of Texas State University, as well as University of Dublin’s Eadaoin W. Griffin, Sinead Mulally, Carole Foley, Stuart A. Warmington, Shane M. O’Mara, and Aine M. Kelly.

Likewise, stress increases levels of cortisol, and lower-income people tend to experience more chronic stress, leading to higher levels of cortisol, according to Northwestern’s Edith Chen and Gregory E. Miller with Sheldon Cohen of Carnegie, and separately by Cornell University’s Gary Evans and Michelle Schamberg.

Tine and Butler investigated these diverse findings by asking volunteers to:

Gary Evans

Items include:

  • My parent was fired from his/her job
  • I was a victim of a crime
  • A close friend or family member had health problems
  • My parents divorced or separated
  • I had problems being liked by classmates

Participants also completed three reading comprehension tasks from Sharon Weiner Green and Ira K. Wolf’s GRE Preparation items.

After 45 minutes, participants monitored heart rate to ensure that it was within 10 beats per minute of pre-test measures of resting heart rate.
Brief aerobic exercise sessions eliminated the gap between “Executive Function” performance scores for talented volunteers from lower-income and high-income backgrounds.

Lower-income participants who exercised aerobically had reading comprehension scores comparable to their higher-income counterparts, around 90%,
Likewise, people who exercised significantly improved Selective Visual Attention (SVA) scores, but the video-viewers’ scores did not change, suggesting that exercise was the “active ingredient” in these performance improvements.

In addition, volunteers who exercised and reported higher chronic stress level achieved higher SVA scores and greater SVA score improvement than those who reported less chronic stress.
Cognitive performance improvements were maintained 45 minutes after exercise.

These findings suggest aerobic exercise as an effective, low-cost intervention to reduce achievement differences between people from lower-income and more affluent backgrounds, and this could contribute to increasing the number of diverse applicants in selective higher education settings and skilled employment – as well as increasing endurance, cardiac health, and reducing stress.

-*How have you seen workplaces encourage participation in aerobic exercise for the next generation of potential employees as well as current employees?

-*Do organizations receive more benefit from reducing health care costs and health-related absences or from increasing attention, innovation, and productivity?
