A Simple Model to Demonstrate the Critical Flicker Fusion Frequency Using Microsoft Office Powerpoint

Background: The critical flicker fusion frequency (CFF) is the frequency at which a flickering light isperceived as a continuous light. It is an index of visual temporal processing. It is affected in several diseaseconditions like hepatic encephalopathy, multiple sclerosis, age related macular degeneration and cataract.We wanted to demonstrate the phenomenon to undergraduate medical and health science students to helpthem understand the concept using a personal computer with Microsoft office power point suite.Aim: The aim of the study was to demonstrate this concept of CFF using a personal computer with Microsoftoffice power point suite in small groups to undergraduate medical and health science students and to take asurvey from the students regarding the demonstration and its outcome in understanding the concept of CFF.Material and Methods: It is a cross sectional survey obtained from the medical, dental and allied healthscience students following the demonstration of CFF using the personal computer with Microsoft officepower point suite in small groups.Results: Our results have shown that the demonstration have helped 94% of the students in understandingthe concept of the CFF. 91% of the students felt that the demonstration has helped them in reviewingthe topic.98% of the students felt that they would recommend the demonstration to future batches of thestudents. 86% of the students said that the demonstrations made the learning fun and exciting.Conclusions: The demonstration of CFF using the Microsoft office power point suite have helped thestudents to understand the concept evoking interest and enthusiasm as they were able to relate the conceptby demonstration and seeing it for themselves.
