Plymouth university webinar 12jun2003 judy edworthy fraser reid liz hellier


Judy Reed Edworthy is Professor of Applied Psychology, in the School of Psychology of the University of Plymouth, whose specialty is psychoacoustics. Her work has centred on auditory alarm implications throughout different areas. Her studies seek to improve auditory alarms.She is a Fellow of the Academy of Social Sciences.

Her two main areas of research interest are the applied cognitive psychology of sound and the psychology of music. In terms of the applied cognitive psychology of sound, her main interest is in the design, application and underlying theory surrounding the use of alarms in both everyday environments and specific high-workload applications. Here, she carries out both research and commercial design work. Her second area of research is in the cognitive psychology of music, and her current interest lies in the aesthetics of popular song, particularly the impact of complexity, repetition, and song structure on the enjoyment of popular song. She also has interests and publications in the psychology of visual warnings.

She appeared on BBC's 'The Code' in 2011. Judy illustrated the relationship between sound and mathematics demonstrating that certain sounds affect us our brains decipher their patterns.
