ref: Brown-2001.11 tags: Huntingtons motor_learning intentional implicit cognitive deficits date: 0-0-2007 0:0 revision:0 [head]

PMID-11673321 http://brain.oxfordjournals.org/cgi/content/full/124/11/2188 :

  • 16 genetically-confirmed Huntington's patients (and matched controls) trained on a task using trial and error learning (intentional), and implicit learning (unintentional).
  • the task setup was simple: they had to press one of four keys arranged in a cross (with center) either in response to commands or while guessing a sequence of a few keys.
  • Within the random, commanded task there was a sequence that could/should be noticed.
  • Huntington's patients performed worse on the intentional learning segment, but comparably on the implicit learning / implicit sequence awareness, though the latter test seems rather weak to me.
