The purpose of this Master’s Thesis is to study the relationship between the use of information systems and age. Aging brings along changes in people on physical as well as cognitive levels. Decrease in efficiency of memory processing, deterioration of vision and other facts might have influence on the ability to adopt and use information systems. The number of aging people particularly in western countries is on the increase. They are becoming a significant consumer group whose needs and special features should be taking into consideration while developing information systems. The theory section of the study focuses on cognitive ergonomics, memory and usability. Interviews were conducted to collect data on the influence of age on adoption of the information systems to support the theory. The purpose of the interview was to find out which facts influence the use of information systems, computer and mobile appliance in this case. The theory reveals that age does affect learning and adoption. Learning and bringing information back to memory requires more time and repetition. Taking a new program or operating system into use might feel demanding and frustrating. Age does not take away the ability to learn though cognitive functions decrease. A positive attitude, enthusiasm and motivation play a large role. The brain remains very elastic during the whole lifespan as long as it is put to work and the mind is kept open for new things.
