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 multi-task performance in demanding environments.

“We have used the Framework in several trials assessing the potential for herbal extracts and nutraceuticals to relieve stress. 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.”
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.”

Department of Psychology, University of Central Lancashire
“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.”
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 multi-task. 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 multi-tasking demands offered a reliable benchmark for studying attention and visual behaviour under pressure.
