Methodological control of semantic priming in Alzheimer's disease
Article Abstract:
Semantic priming exhibited by individuals with Alzheimer's disease (AD) is greater than normal in long stimulus onset asynchrony (SOA) condition, but normal in short SOA condition. A study using probable AD and older normal persons reveals that methodological manipulation can elicit hyperpriming and normal priming in AD subjects. AD subjects slow down in the long-SOA condition, whereas older normal individuals speed up. The results suggest that the increase in priming by AD subjects is related to controlled processing rather than degradation of semantic networks.

Age-related reduction in 3-D visual motion priming
Article Abstract:
It has been established that 3-D visual motion priming is initially similar in younger and older adults but deteriorates rapidly in the elderly. Three experiments were used to compared 3-D motion priming in younger and older adults. These experiments investigated whether older adults show motion priming for 3-D objects and, if so, whether motion priming is comparable in younger and older adults. It is possible that changes in the temporal characteristics of motion mechanisms could account for reduced 3-D motion priming in older adults.

Age-related priming effects in social judgments
Article Abstract:
Older adults are likely to form impressions biased toward the primed trait constructs, while younger adults are more aware of the primed information and are more conscious of its perceived influence. This was found in a study of age-related priming effects on judgments about people. Results affirmed the hypothesis that declines in the efficiency of controlled processing mechanisms associated with age during adulthood are related to increased susceptibility to judgment biases.
