Multi-Tasking and Performance – Most People are NOT Supertaskers

This reprint from The Ergonomics Report reviews studies investigating multi-tasking that found that people are generally limited to performing two mental tasks at any given time; that most people exhibit performance decrements under multi-task conditions; a small percentage of people, labeled "supertaskers," are able to perform two tasks at a time without any performance degradation (sorry, but chances are, you're not one of them).

Stretching and Ergonomics

Why, when implemented in the workplace, do resolutions that encourage workers to partake in on-the-job exercise programs, install and use stretch-break reminder software at their computer workstations, or commit to a personal wellness plan, so often get confused with ergonomics?

Listening: A Powerful Macroergonomic Tool

Workplace problems must be addressed in context, and the key to understanding context is careful and respectful listening. In this reprint from The Ergonomics Report, renowned Ergonomist Andy Imada shares workplace experiences and solutions with journalist Jennifer Anderson. Imada's insights take us well beyond a typical ergonomics risk factor focus by considering psychosocial factors that often trump workstation-based improvement efforts. For example, according to Imada, "people will not remember you for what you did, or what you said or how many millions of dollars you saved. They will remember you for how you made them feel."

We Told Them to Lift with Their Legs, But They Just Won’t Listen!

Common wisdom says we should lift with our legs, not our backs. Some companies mistakenly base much of their ergonomics strategy on training employees to "lift with your legs." This research study sheds light on why many people typically don't lift with their knees, and instead use a back-lift strategy. In this article, reprinted from The Ergonomics Report, study reviewer Peter Budnick offers his thoughts on how companies can apply this new knowledge.

Hospital Bed Research to Improve Patient and Nurse Safety and Performance

Researchers have devised new methodologies and metrics to analyze patient migration while laying in hospital beds. The results of the study reviewed here should help hospital bed designers better understand patient migration patterns and influence new designs that will reduce migration, as well as reducing the pressure ulcers and skin tears migration can cause, and reducing the caregiver patient repositioning tasks that lead to high rates of back injury among nurses.

Research Review: Value of Back Injury Prevention Training Questioned (reprint)

While a staple of many health and safety programs, the value of back injury prevention training is strongly challenged by a review of eleven recent studies.

Thumb Reach Distances and Envelopes for Handheld Devices

Applied researchers Otten, Karn and Parsons where tasked with designing a handheld consumer camera requiring thumb operated controls. They were surprised to find that very little data was available for such devices, so they embarked on a collaborative research and design project to collect their own data, which they later shared in the published journal Human Factors. Peter Budnick reviews their work, describing it as a good example of "informed design," which he describes requiring an ergonomic, human-centered approach. The researchers also used novel techniques to collect thumb reach distance and envelope data, and also applied the "Mr. Potato Head" method to investigate control location preferences.

You Can’t Achieve Six Sigma Without Ergonomics (reprint)

Reprinted from a 2002 issue of The Ergonomics Report: Any team presented with a big project that seemingly becomes more and more complex might groan at the prospect of putting ergonomics into the mix. But with a Six Sigma project, ergonomics neither conflicts with nor takes resources from other management or process systems that may already be implemented within a company. Instead it adds to the proper execution of the Six Sigma process. Authors: Jeanie Croasmun, Rachel Michael. Contributors: Ben Zavitz, Mike Wynn.

Participatory Ergonomics: A Path to Sustainable Ergonomics

Following up on his popular Participatory Ergonomics webinar, Peter Budnick further discusses the importance of Respect for People in Continuous Improvement systems like Lean, arguing that it's impossible to achieve Operational Excellence without Ergonomics, and that Ergonomists can play a valuable leadership and participation role in such initiatives. He illustrates the importance of Respect for People with examples from his work with Ergonomists Without Borders, and also shares his slides and a recording of the webinar for interested readers.
