Another study on sense of time
Vrabel, Christopher J. (2009) Sense of Time, Inhibition and Working Memory in College-Aged Students. PhD dissertation. Indiana University of Pennsylvania.
Inhibition was not related to time reproduction or time discrimination. In addition, time reproduction was not related to working memory, ADHD or trait anxiety. However, time discrimination was related to working memory, self-report symptoms of ADHD and trait anxiety. Subsequent analyses showed that visuospatial working memory predicted above and beyond verbal working memory. When tested in a stepwise fashion, self-report measures of ADHD and trait anxiety both predicted significant variance in time discrimination ability above and beyond working memory. Further analyses showed that, although participants were able to solve medium level time discrimination items using working memory, as the level of difficulty increased and exceeded the capacity of working memory, participants were forced to rely more on their sense of time. The results of this study provide evidence that symptoms of ADHD and anxiety are related to “purer” deficits in sense of time as related to an internal clock.
