Article Abstract:
Older adults may have problems with route learning, though aging does not affect all aspects of learning routes. Research using two experiments shows that older adults may recognize landmarks as well as younger adults but they may not choose landmarks that are most relevant to identifying a route. Older adults tend not to perform as well in tasks involving temporospatial organization. There are individual differences among older adults in their ability to translate 2D models into 3D space.

Article Abstract:
Memory can be categorised in two ways, explicity memory involving retrieval, and implicit memory. Alzheimer's Disease patients have their explicit memory affected, as is shown by a study involving the performance of reading tasks by three groups of people, Alzheimer's patients, older adults and younger adults. These patients initially find reading and rereading meaningless texts to be difficult. Alzheimer's patients appear to have all priming mechanisms intact, as do older adults.

Article Abstract:
Ageing is associated with slowing of behavior, and processing speed can affect cognitive measures. A survey of 105 older adults and 144 younger adults tested geometric, alphanumeric and motor speed. The results show that factor loadings and factors did not vary across age groups, while unique variances, variance-covariance matrices and interfactor correlations did vary across age groups. The results also indicate dedifferentiation as age increases.
