White matter volume predicts reaction time instability

  title={White matter volume predicts reaction time instability},
  author={Kristine B. Walhovd and Anders M. Fjell},
Information processing speed is a central concept in cognitive psychology and neuropsychology. Previous studies have mostly focused on mean reaction time (RT), and largely ignored intra-individual differences (the standard deviation of the RT: sdRT). Still, intra-individual inconsistency across trials has been shown to correlate with age, neurological disorders, intelligence, and performance on cognitive tests. However, sdRT has not been correlated with neuroanatomical variables. Such knowledge… CONTINUE READING
