Abstract/OtherAbstract:
The authors examined 400 ms delay eyeblink classical conditioning in 20 participants with Fragile X syndrome ages 17 to 77 years, and 20 age-matched, healthy control participants. The participants in the Fragile X group demonstrated impaired learning and abnormal conditioned response timing. Adults with Fragile X (n=16) were also tested at two successive 12-month follow-up sessions to examine reacquisition and long-term retention. Participants in groups who were older and younger than 45 years demonstrated significant learning during each reacquisition session. Younger participants demonstrated greater retention of the conditioned stimulus/unconditioned stimulus association at each follow-up session than older participants. Fragile X impairs the acquisition and timing of conditioned eyeblink responses, but with repeated training adults with Fragile X syndrome show significant plasticity.
