The study examined the impact of instruction presentation modes in computerized cognitive training on its acceptance among older adults aged over 65 without known cognitive impairments. The research involved 128 participants with a mean age of 71.5 years, of which 70% were female. Two types of instructions were compared: without visual cues and with visual cues. Results showed that instructions without salient visual cues were more acceptable for complex functional games. Individuals with lower confidence in their cognitive abilities were less receptive to cognitive training, except for highly familiar games. The study emphasizes the importance of simple and personalized instructions to improve acceptance of computerized cognitive training and highlights the need for tailored interventions for older people.
