  • Values are median (interquartile range).

  • Scoring systems used: (a) number of idea units recalled; (b) time to complete task (with the penalty for errors) in seconds; (c) number of digits recalled correctly; (d) number of items identified correctly; (e) number of original ideas; (f) number of different categories of ideas; (g) total number of ideas.
