A preliminary study of cognitive failures in open plan offices

an article by Brian Purdey (Bond University, Gold Coast, Australia) and David Leifer (University of Sydney, Australia) published in Facilities Volume 30 Issue 11/12 (2012)

Abstract

Purpose
The purpose of this paper is to describe the application of a new method using instruments with increased ability to objectively assess and quantify the performance impacts on office workers in built environment settings.
Design/methodology/approach
A Distractibility Index (DI) was calculated for sample employees, who then used a computer-based instrument in two settings to evaluate cognitive impairment
Findings
There was measured cognitive impairment in higher distracting work environments. There is potential to use DI to predict performance detriments and aid better workplace design/management.
Research limitations/implications
The study employed only a small sample size. The level of noise and other distractions in the settings studied need to be measured objectively. There is a need to differentiate between various sources of distraction in terms of their impact on cognitive impairment.
Practical implications
The findings of this paper can help to improve workplace performance, with less reliance on physical design solutions.
Originality/value
Workplace performance evaluations typically use subjective measures and self-assessments. Modern work is increasingly cognitive, and hence new computer-based and more objective tools are required. The tool used in this research has been highly validated in other applications.

The “Myth” of Media Multitasking: Reciprocal Dynamics of Media Multitasking, Personal Needs, and Gratifications

an article by Zheng Wang and John M. Tchernev (The Ohio State University, Columbus, USA) published in Journal of Communication Volume 62 Issue 3 (June 2012)

Abstract

The increasing popularity of media multitasking is frequently reported in national surveys while laboratory research consistently confirms that multitasking impairs task performance. This study explores this apparent contradiction.

Using dynamic panel analysis of time series data collected from college students across 4 weeks, this study examines dynamic reciprocal impacts of media multitasking, needs (emotional, cognitive, social, and habitual), and corresponding gratifications. Consistent with the laboratory research, cognitive needs are not satisfied by media multitasking even though they drive media multitasking in the first place. Instead, emotional gratifications are obtained despite not being actively sought.

his helps explain why people increasingly multitask at the cost of cognitive needs. Importantly, this study provides evidence of the dynamic persistence of media multitasking behavior.
