Odiont‚ Wolters & van Giezan (2012)‚ tested the effect of questioning participants multiple times as well as over a specific duration. The study showed that participants had lower accuracy when he or she was questioned much later‚ but did not show a significant decrease in amount of recalled information. The repeated questioning also did not affect the participant’s ability to correctly recall the event

and the pragmatic quality. Inherent quality is mainly concerned with the accuracy and correctness of information whereas the pragmatic quality involves the value the correct and accurate data possesses that could support in the business operations (Ravichandran and Lertwongsatien‚ 2005‚ pp. 237–276). It should be noted that the data or information that has no value for the business is of no quality‚ despite its accuracy or correctness‚ for the enterprise.
