  Title Correlates of Within-Person (Across-Occasion) Variability in Reaction Time Type Journal Article
  Year 2005 Publication Neuropsychology Abbreviated Journal  
  Volume 19 Issue 1 Pages 77-87  
  Keywords reaction time; within-person variability; age; Aging; Repeated Measures  
  Abstract A total of 420 adults between 18 and 91 years of age carried palm pilot (Palm M100; PalmOne, Milpitas, CA) devices and performed several reaction time trials when prompted at random times during the day. On the average, within-person variability in median reaction time from one occasion to the next was nearly the same magnitude as the between-persons variability in across-occasion mean reaction time. Analyses controlling the variation in one variable when examining relations involving the other variable suggested that an individual's mean reaction time is a more powerful predictor of relations with age and with the level of various cognitive abilities than his or her across-occasion SD.
