Trusted by Researchers, Universities & Industry
For more than 25 years, the Purple Framework has been used in university psychology laboratories, clinical trials, human-performance studies and applied research across a wide range of disciplines from chewing gum to defence. Its reliability, flexibility and scientific grounding have made it a preferred tool for investigating stress, cognition, attention and multitask performance in demanding environments.
Professor Andrew Scholey
Professor of Human Psychopharmacology, Northumbria University
“I have used the Framework in numerous trials over the last three decades, including at the Human Cognitive Neuroscience Unit (now the Brain, Nutrition and Performance Research Centre) at Northumbria and the Centre for Human Psychophamamcology in Melbourne, as well as with academic and industry collaborators in New Zealand, Australia, US and Europe. It it my preferred approach for assessing the potential for herbal extracts and nutraceuticals to relieve stress and improve performance. The system has many advantages over other stress paradigms in experimental psychology and psychopharmacology, particularly the ability to repeatedly use the platform with little attenuation of the behavioural stress response.”

“We used the Multitasking Framework (MTF) as a computerized stress test in a human nutrition clinical trial. The MTF allowed us to measure changes in subjective and physiological stress markers before and after participants consumed different bioactive compounds designed to reduce stress responses. Our clinic staff found the MTF very easy to implement and use.””

“One of the easiest interfaces I’ve encountered on a PC — so simple to use I had to remind myself I wasn’t on a Mac. Its flexibility makes it ideal for both research and undergraduate teaching.”
Professor Ronan O’Carroll
Department of Psychology, University of Stirling
“We found the Framework extremely useful in our research on individual differences in psychophysiological reactivity to cognitive stressors. The ability to modify the difficulty of the tasks was particularly valuable, and the system itself is exceptionally user-friendly.”
Howard Taylor
Department of Psychology, University of Stirling
“The programme works well. The tasks are clearly explained, demo mode helps eliminate confusion, and features like concealed scoring and adjustable workload make it a highly flexible research tool.”

BBC Horizon – How to Sleep Well with Michael Mosley (2022)
In this clip, Michael Mosley uses the Purple Framework to assess how a sleepless night affects his ability to concentrate and multitask. The segment highlights how reduced sleep can significantly impact cognitive performance.

Laser Eyetracking Study
Researchers used the Purple Framework as a controlled test environment while analysing gaze patterns with a laser eye-tracking system. The multitasking demands offered a reliable benchmark for studying attention and visual behaviour under pressure.
