Larger nondeclarative than declarative deficits in learning and memory in human aging
Article Abstract:
A comparison of classical conditioning, using two paradigms of the nondeclarative eyeblink classical conditioning (EBCC), with verbal learning using the declarative California Verbal Learning Test (CVLT), reveals significant age variations in the EBCC task. The 400 ms and 750 ms paradigms of the EBCC task initiated larger and equal age differences, respectively, than those in the CLVT task. The results invalidate the theory that nondeclarative learning and memory sustain the impact of aging more than declarative learning and memory in same subjects.

Predictors of eyeblink classical conditioning over the adult age span
Article Abstract:
Eyeblink classical conditioning was believed to be affected by age-dependent factors. Using this as a hypothesis, a study was conducted among individuals between 20 to 89 years old to determine the predictors of eyeblink conditioned response and its correlation with age differences. Results indicated that variables such as blink reaction time and explicit memory did not predict conditioning while lesions in the cerebellum affected timed-interval tapping and performance.

Number of trials needed to assess human eyeblink classical conditioning
Article Abstract:
A study shows that eyeblink classical conditioning performance is reliably assessable in 63 trials. Trials exceeding this limit do not yield further conditioning effect. Use of fewer conditioning trials increases efficiency in research and makes eyeblink classical conditioning more practical for both research and diagnostic purposes. These results are based on study with groups of young, middle-aged, and elderly normal and patient adults.
