Abstract
|
|
|
|
A series of cognitive tests (memory, attention, language, executive function) were administered to 67 young and old participants aged from 20s to 70s. Each task was programmed using a computer software and performed on the computer. For the memory and language tests, participants responded verbally to the instructions and for the attention and executive function tasks, they responded by pressing big-sized buttons designed for people with disabilities. The study demonstrated overall age-related cognitive deficits in older adults but showed that some cognitive functions, such as attention and language, seemed more resilient to aging than others. The results also showed that memory impairments in older adults seemed due to a lack of encoding rather than retrieval; education level turned out to be an important factor in language but not to other cognitive functions and generally attention declined as people got older and their attention deficits were even more prominent while doing more complex attention tasks. Statistically controlling for attention, however, did not directly affect the test results of other cognitive functions.
